Wow, this mechanic knows where he's talking about! Great. Only things missing, are protective gloves, since the ring gear is extremely hot and could cause severe burns on your hands.
On the install you can also put the fly wheel in the freezer for about an hour if you don't have a oxy/ace torch. Then a LP torch should work. As always great vide!!!! thumbs up!!!
Whenever I did a clutch job on my old Fords I would always check the teeth on the ring gear closely. The compression of the engine often meant it stopped frequently at the same point of rotation. The starter gear would wear the ring gear more in that one area. What I do is heat the ring gear with the oxy acetylene torch to expand it, carefully drive it off the flywheel with a blunt punch (brass punch is best..). Keeping it hot (or reheating it) I flip it over and carefully drive it back onto the flywheel giving all of the ring gear teeth a brand new surface for the starter gear to engage. Like a brand new ring gear, but for zero cost.
Thanks a bunch guys! I'm about to change the ring gear and starter in an old Timberjack cable skidder with an old Continental engine on it. wasn't quite sure what I was getting into as it will be my first attempt at changing a ring gear. I feel confident with attempting it now. Thanks again guys! Keep up the great videos!
Perfect instructional video from an expert. Thank You, My ring gear replacement went as easy as you demonstrated. Did I say thank you? Thank You (smile).
Thank you so much man, You just made my day. I have a Isuzu NQR with a Bad Flywheel. They wanted $685.63 for a new one. You just saved me a few hundred dollars. Thanks Man ..ONE LOVE MON
My mechanic & I watched this video. When he gently tapped it & it came right off, we both looked at each other with a "Yeah, right" look. Then he heated the new one and dropped it right on. My mechanic & I were laughing by now. We know how it looks so easy, but in reality it never works that way. HOWEVER, when we did ours, it worked exactly like the video!! We couldn't believe it worked so smoothly. Thanks for the great instructional video!!
Back in the day the old AMC 6 cylinders used Ford starters with a longer drive gear. When some idiots used a regular Ford starter the shorter drive gear would only engage about 1/8th of an inch of the ring gear teeth. Needless to say mechanics got to replace a whole lotta AMC ring gears back then.
I don't see why you'd need the shim between the flywheel and crank. You took material off the clutch surface of the flywheel, but the pressure plate bolts to the same surface. So even if you took a good amount of material off, the pressure plate would end up moving towards the engine along with the clutch disk. The only thing that would possibly need adjusting is the clutch linkages since the pedal would have to move a little farther for the throwout bearing to contact the pressure plate. A shim between the flywheel and crank wouldn't affect the distance between the clutch disk and flywheel anyway, since the pressure plate is bolted directly to the flywheel.
First one I did at 14 years old, just hack saw it of and then split last part with coal chisel and the put new ring gear in fire until just starts to glow slightly and then it slide on fly wheel and let cool down any way good video to teach people who get ripped of by mechanics saying you need a new fly wheel.
If the hardened ring gear starts to glow at all in the fire, then the heat treatment of the teeth is damaged. Teeth are hardened to over 40 Rockwell C, getting it red would drop that to under 10. Much better is to put the ring in your kitchen oven on full for about 30 - 45 minutes.
You don’t need to heat the ring gear to remove it. A few wacks with the chisel and it will pop off. Heat the new ring gear up and drop it on. Let it cool and you’re good to go. I do this and have done this hundreds of times working in a fleet ford shop.
Just had a manual Honda Civic with a spinning ring gear. I wasted money on starter motors, I had no idea these could come loose. Must have heated up when the old clutch (replaced) went bad. I spot welded a few points on the interface, rather than do an entire replacement job. Don't know if it will work, but my initial starter test is good.
What do you suppose was the cause of the damage on the original ring gear? Was it a bad starter or was it driver error for starting a vehicle that's already running?
Thank you. Why cant i just clean up teeth with angle ginder and turn ring gear over. Chamfer on my ring gear is big enough on both sides to sit down flat. Also why the shim, surely if clutch is bolted to flywheel the whole assembly just moves back .020".I have a hydraulic system and i can adjust push rod from slave cylinder to compensate the difference.
Good point. The body of the ring gear should be relatively soft, the teeth are hardened. Should be able to drill through the body then split with a cold chisel.
i found the ring gear on my 7.3 bad in four different places, apparently the engine always stopped and wore in four different places, thats where the starter always slammed into the gear. replaced it easily
Ive just had my flywheel machined and i dont believe they have used a shim to push it forward, its making a ticking noise from the flywheel now. Would anyone know if that would be the cause of the ticking?
@RegniA Short answer is ring gears are installed on factory flywheels in a similar way - heated and layed/pressed on) - so this method is not much different although a bit slower to do.
hi, I dont under stand why machining the flywheel will make the distance from the disc to the flywheel too short. Movine the disc too far towards the end of input shaft of trans, ???
On transmission with hydraulic slave cylinders on the transmission bellhousing, you need to maintain a distance between the clutch mating surface and throw out bearing.
do you have any idea of what is the perfect math of ring gear for a chevy s10 1996 v6, manual trans.. there is 2 a 142 thooth and 168... a need help...
Good point, better to re-surface the flywheel AFTER fitting the new ring gear. It can be surprising how much force the shrink fit can apply to the flywheel.
no man the concept actually relies on uneven heating causing the ring to heat and expand much more than the flywheel itself. this rapid heat and expansion allows the expanded ring to be hammered off. if you were to do this in an oven the flywheel would expand at the same rate as the ring which would leave you with the same sort of tension you experience at lower temperatures. but it would be hot... and you would be frustrated...
I think his question is for installing the new gear...If no torch is available, just take a chisel and put it between 2 teeth on the installed gear, and give it a smart whack. go around the gear in 8-10 or more equal spaced places and it should fall off. Each little 'ding' stretches the outside diameter a little, and usually works. Yes, putting the gear in the oven @500 would do it. Takes about half hour to get it hot enough, after the oven is hot!! Put the flywheel on the floor right beside the oven, cause you will not make it any further with the hot and expanded gear. Seconds count here!! Don't 'grab' it with a metal object.. heavy gloves!
A kitchen oven would be fine. Don't want to get it to much more than 400 - 450 or the hardness of the gear teeth will be reduced. Let it soak in the heat for about 30 minutes, then it should drop on fine.
Ya' gotta' love how he heats one side and lets it cool while he heats the OTHER side, then installs it back on the flywheel!!!! You only have to heat 4 or 5 inches of it.
I heard of another way of putting on by putting the fly wheel in dry ice to shrink it, that way the ring gear would slide on would that work as well? anybody try that method before? thanks for the video, never thought of the shim i better look into that. got to get my 50 ford back on the road!
You need to make the temperature difference between the two of them to be around 300 - 350 F. Either heat the ring by that much or cool the flywheel by that much or a bit of both. Cooling the flywheel by 300F would be very difficult and would make it rather brittle, perhaps cracking it even.
imo his ASE certification explains quite a lot , SMH ! Just knock the daxn thing off clean appropriately heat the new one & set it on ! & have never seen 15 or so thousands off a flywheel face do anything to a clutch !
Totally ludicrous that he said to put a shim between the flywheel and the crankshaft. All he did was move the flywheel away from the crank. The clutch disc is bolted directly to the other side of the flywheel smashed between the pressure plate and it did not move the clutch plate away from the flywheel I cannot believe that anybody would believe that. Anyone that thinks for one second that he needed that shim rethink the physics! And yes you heat the ring gear to make it expand it falls off the flywheel you heat the new ring gear so it expands and it falls onto the flywheel. But think about the other part if you surface the flywheel it's still the same distance when you bolt the pressure plate on nothing changes except the throw out bearing moves a Little closer to the engine. Which means all you do is adjust your clutch linkage ever so slightly would you have to do anyway because you just installed a new clutch disc. Once again the shim is ludicrous.
Another professionally informative video, thanks for everything you do. I'm just a household DIY'er and I enjoy watching your videos.

re:"and carefully drive it back onto the flywheel" Sure you drove it back on , LOL !
That’s a bloody good idea - I’m gonna give that a try 👍

Don't have access to a torch? Freeze your flywheel overnight, throw your ring gear in the oven for about an hour, and viola.
Excellent job ! Very informative for us DIY guys.. Keep up the good work !!!

+SuperKONr ya u never ever shim behind the flywheel
not about that side, it's about how the starter teeth connect.....
Great video, straight to the point !!!
Thankyou very much uploading this informative video . I admire your efforts 🙋♂️
That's very cool.I've never seen anyone do that befor.Great job and thanks for sharing it with everyone.
thanks! Think Ill leave this one to my mechanic. :o) Will pull the motor and he can do the rest.

Thank you for an informative video. I just did it. Works perfekt.
Short and informative 🐐🙏🏽
Great video, just the info I needed!
Before you start heating the new ring gear, clamp a couple of vise grips upside down just on the teeth to handle it with.
Absolutely, very nicely Done !!!
You don’t need to heat the ring gear to remove it. A few wacks with the chisel and it will pop off. Heat the new ring gear up and drop it on. Let it cool and you’re good to go. I do this and have done this hundreds of times working in a fleet ford shop.
That's what I'm talkin about
Always well spoken
Nice work guys.

Hey thanks for such a informative video. I want your help regarding where could I find ring for the sonata nf 2006. Hope u could help
What do you suppose was the cause of the damage on the original ring gear? Was it a bad starter or was it driver error for starting a vehicle that's already running?
Excellent
Sweet thanks

Kollam pwolli saanam 👍👌
Heating the ring gear makes the teeths softer. How is this afecting the harding of the teeths? Don't they last less?
First time doing this is it not important for the teeth on the ring gear to be in the exact same spot as the old ring gear?
You can also drill a hole through the ring gear and chisel it off on some vehicles
Good point. The body of the ring gear should be relatively soft, the teeth are hardened. Should be able to drill through the body then split with a cold chisel.
i found the ring gear on my 7.3 bad in four different places, apparently the engine always stopped and wore in four different places, thats where the starter always slammed into the gear. replaced it easily

cool
@spelunkerd
The flywheel's just a thin piece of metal with a non-removable ring gear that bolts to the torque converter with a couple of bolts.
No, that's a flexplate.
How about adjusting the tortch correct
@RegniA Short answer is ring gears are installed on factory flywheels in a similar way - heated and layed/pressed on) - so this method is not much different although a bit slower to do.
hi, I dont under stand why machining the flywheel will make the distance from the disc to the flywheel too short. Movine the disc too far towards the end of input shaft of trans, ???
On transmission with hydraulic slave cylinders on the transmission bellhousing, you need to maintain a distance between the clutch mating surface and throw out bearing.
@bo diddly correct. That's why most all shops shim the throw out bearing and not the flywheel.
Is there a reason the ring gear can't be flipped to use the other side of the teeth?
U can . But i don't know is it good thing or not. When we changed our ring gear previous owner was already flipped it and used it.
Some are cut a certain way that would bind if it was flipped
What about automatic...and how did you get to it
do you have any idea of what is the perfect math of ring gear for a chevy s10 1996 v6, manual trans.. there is 2 a 142 thooth and 168... a need help...
isuzu rodeo v6 is exactly the same
Get your VIN number and call the parts guy at your dealer.
thank you sir please tata ace pickb engine flywheel ring Gear change video
where to buy the right RING.......?
Do this before resurfacing the flywheel so it doesn't become warped.
Good point, better to re-surface the flywheel AFTER fitting the new ring gear. It can be surprising how much force the shrink fit can apply to the flywheel.
If you don't have a torch. Use oven 550 2hrs
How does this look on an automatic transmission?
It doesn't! Buy a new flexplate.
Done it for 40 years and never used it torch to take it off only to put it on
No need to heat to take ring gear off . Heat to put back on .
Can you do this with an automatic transmission?
flex plate has welded ring gear. replace as a unit. Not too expensive anyway.
NO.
Does heating the ring gear change the temper of the gears teeth?
no not at all because you don't have to get it that hot
This is the real world.
I dont have axcess to a torch, how hot are you heating the gear?
could the temp be reached in a home oven?
lol
no man the concept actually relies on uneven heating causing the ring to heat and expand much more than the flywheel itself. this rapid heat and expansion allows the expanded ring to be hammered off. if you were to do this in an oven the flywheel would expand at the same rate as the ring which would leave you with the same sort of tension you experience at lower temperatures. but it would be hot... and you would be frustrated...

Ya' gotta' love how he heats one side and lets it cool while he heats the OTHER side, then installs it back on the flywheel!!!! You only have to heat 4 or 5 inches of it.
what about flipping it. it cost $350 for just ring gear on my bobcat
Tell them to keep the SOB and buy it somewhere that won't stick a gun in your face. The whole flywheel isn't worth over $75.
excellent vid. i cringed a little that you weren't wearing heat proof golves.
Legit
Put the Ring Gear in the Kitchin Oven ,,, at Plus 400 Degrees and it will be a lot easier
No reason to torch it off just a brass drift will take it off
Everything made sense until he started heating the ring gear to get it off
I heard of another way of putting on by putting the fly wheel in dry ice to shrink it, that way the ring gear would slide on would that work as well? anybody try that method before? thanks for the video, never thought of the shim i better look into that. got to get my 50 ford back on the road!

@3:30 this is called a chamfer
imo his ASE certification explains quite a lot , SMH ! Just knock the daxn thing off clean appropriately heat the new one & set it on ! & have never seen 15 or so thousands off a flywheel face do anything to a clutch !
no because its a whole different flywheel
You absolutely do not warm a ring gear to remove it. 😂
What happened when the Starters is not start the Car
The Starters just Lock don't want to turn
I just need someone to drop my transmission and take the flywheel off so I don't have to do it.
Anywhere between 500 and 700F is hot enough
700F is TOO hot, will affect the hardness of the ring gear teeth, making them softer and more prone to early wear.
Totally ludicrous that he said to put a shim between the flywheel and the crankshaft. All he did was move the flywheel away from the crank. The clutch disc is bolted directly to the other side of the flywheel smashed between the pressure plate and it did not move the clutch plate away from the flywheel I cannot believe that anybody would believe that.

Which means all you do is adjust your clutch linkage ever so slightly would you have to do anyway because you just installed a new clutch disc. Once again the shim is ludicrous.
Someone makes Flywheel Ring Gear`s for outboard Motors , Don`t Need The Ass. Someone Must no Where I can Find It
Flywheel removal
i say change the fly wheel instead of resurfacing
That was beginning to think he was smart obviously I was mistaking
What a great video!
