Motorcycle Starter Clutch Rebuild How To
Vložit

- This video shows you how to rebuild a slipping motorcycle starter clutch. This is a very common item to wear out in these old bikes simply due to age but is unfortunately something that can keep your bike from starting. This will be a very similar process on your CB750s, CB900, GL1100, GL1200, CB550, GL650 and many more!
On this CX500 you can see that one spring was actually broken with another being compressed and worn. These two things keep the bike from starting. Note that I looked for a long time for any broken spring material and did not find any. It would have been very soft metal and not able to cause damage anyway.

I haven’t worked on bikes in years. I really appreciate these videos so when I do get a bike project I’ll be a bit ahead of the game. Thanks young man!
Thank ya much!
I have none of these bikes but it's always a pleasure watching good craftsmanship :)
🙏🙏
I love your teaching videos. I don't have a Honda, but love videos like these anyway
I very much appreciate that! The way I see it is that none of this is bike specific. You can use the fundamentals and problem solving on anything.
Another excellent instructional video. I hope my CX500 won't need this soon. Engine was just out and back in...don't want to repeat that too soon.
Lucky its not too terrible once in there should you need to
Very helpful, made me confident to pull the engine on my 85 Goldwing 1200, thank you!
Happy you found it helpful! It applies to many bikes of the era
Another super how to video, dude you are awesome! Glad I have 2 CXs so I can ride one and fix the other. Such high quality explanations and video work
Glad it was helpful!
You don't want to have to change out the starter clutch on a Honda CBX engine, that job requires splitting the cases to do that, as all the hardware for the clutch & rollers is mounted on the jackshaft assembly. Barrel of fun to replace! If your CBX is apart, this is the time to inspect/replace those rollers & springs before crankcase assembly.
Great video, keep 'em coming!
Definitely Mark. The CBX engine is fully disassembled now and will absolutely get thr clutch components replaced
Love your work, good video.
I did the same job on my V Star, when you pull the flywheel it's difficult to hold it together, top tip, tuck/slide a rag behind the flywheel to prevent bits dropping into the crankcase.
I appreciate it Richard! Solid tip
Honestly, I've never had enough guts to look in there fearing there might be some funny stories putting it back together. But I also wondered what sort of a mechanism is there that releases the flywheel so fast, precise and soft in a way. I knew there were these kegs but to think it's pretty much just a little spring pushing them to create friction is making me smile for some reason. I am no mechanic but it kind of makes me wonder how common this kind of a mechanism is among the petrol, diesel automotive world. Anyway, as always - a great video, focus on details and the format itself.
Pretty common setup actually
One way sprag rollers are common in automatic transmissions and can sometimes even be found in Continental aircraft engine starters.
BAM, engine drops and you laugh - jack goes out - haha! Once again your skills amaze me BJ. Even in your backyard tiny garage, I learn something everytime I watch one of your videos. Among the many informative, demonstrative, and well explained things in this video, my favorite is hearing that nonexistent torque wrech click click click!! 🤔💪🍻❤🤙
Oh man that jack was giving me problems. You can see when we dropped the engine originally I wasn't able to lower it all the way down. We noticed it was almost stripped but decided it had one more lift left in it....WRONG! 🤣 It lasted 5 years so no complaints. Also I HAD to include the torque wrench to make a point lol
@@BrickHouseBuilds Love it!
Have the same with my old Kawasaki 750. All best from England ❤
Definitely similar across many manufacturers
Excellent work and explanation, thank you very much for sharing it!
🤘🤘 hopefully it comes in handy should you need it
My old cb450s had the 3 torque screws come loose. Heard about ut multiple times on the forums too. On that one you need to remove the crankshaft to get to is, since its between the crank bearing holders. That was such a blessing lol. Cleaned it out ultrasonicly and drowned the threads in green locktite.
Thats a lot more work there!
Thanks for the info BJ definitely good to know
Thanks Robert 🤘
Great as always thank you!
🙏🙏 much appreciated
Another cracking video, man! Love the way you explain what's what and how you go about sorting it! Excellent content again!
Keep it up! 🍻🤘💜
Much appreciated, really hoping people find this one as its such a common problem
I'm curious as to where is the other piece of broken spring ended up at, did you find it?
Edit: Never mind I read the description and got my answer.
huge thanks for this!
Hope it proves helpful!
Excellent vedio gentlemen. Very well done.
Thank ya!
Great video
Thank you
I need to do the proper mechanical seal fix this winter, so while I have the back cover off it seems like I might as well do this, since it seems like it's cheap and easy when everything is apart anyway.
Absolutely replace the springs and likely plungers if you are in there
I've done this job twice. Once on a 1983 CB1100f and once on a 1978 GL1000. The inline fours are definitely easier than a Goldwing because you don't have to pull the engine. I'm getting ready to do the job on my 1980 GL1100 now. It sounds like shaking a can full of rocks when I hit the button.
Great video

Thanks Nick
The starter would spin during cold weather starts on my 07 Goldwing. I switched from synthetic oil to conventional oil and that fixed it.
That wouldn't fix this issue.
@@BrickHouseBuilds Agreed, but in some cases switching to DINO oil will make the dogs grip. Worth trying if the starter spins in cold weather, but works other times.
You are exactly right Ronald Cooper. Never use synthetic or semi synthetic, always use mineral oil. Mineral is recommended by the manufacturer.
Always love watching your vids. Always super detailed and very well explained. Btw, being from Puerto Rico, parts are usually a bit of a pain to come by. Do you have any go-to sites for oem pieces and very specific engine internal components? Much appreciated if you or anybody in the comment section could share some knowledge.
Btw keep on killin' it man 🍻
Thank you! For oem sites I use partzilla, cmsnl, and ebay
@@BrickHouseBuilds sweet! Thank you, really appreciate it a ton.
How do you like the HF transmission jack compared to your old scissor jack? I recently bought a Handy lift. I also bought a Handy motorcycle tire machine and electronic balancer. My local shop just retired and there are no other shops with that equipment for around 75 miles in any direction!
Only used it this time so no real feedback yet. I don't like how fast it tries to loft though
Good job enjoyed your video. That particular application seems like it could be maybe a little easier than some others idk I have an '86 cmx450c that has a problem with the starter clutch.
Yours would be very easy as it is accessible from the side of the engine
Thanks for making this video and being so detailed.
My pleasure. Hopefully people find it helpful
I'm also re-furbishing an 81 CX500. It has a CDI ignition. I'm installing a Koso digital tach. Could you give me some guidance on where the signal should come from?
Your gauge will come with a sheet listing the preferred tach signal options. You will have to fine tune it as well with signal selection
great video thx and what kind of puller is that different than a harmonic balancer puller..also about the thrust washer what is its job thankyou!
That is a flywheel or starter clutch removal tool. You can see many on motion pro. A thrust washer is always to take up slack to eliminiate any play a shaft will have.
@@BrickHouseBuildsI did my starter clutch and it made a strange intermitted tapping sound and I can not recall ever seeing that thrust washer until your video so I ordered one and about to do the job again thx BHB
Love the builds! Do you use some sort of software to first design the bikes before working on them or do you just start with an idea and change as you go?
Thank you much! They start with a list of goals like what the bike needs to do. Then they get built to fit. No drawings or anything
Hello very nice and good prefsional guy.. I habe me to one cx650.. But i need some parts. Like tank and pipes of hier filter hiw i can find it please?
Thank you. Your best bet is to simply search online in your area
@@BrickHouseBuilds i am in irland.. I don know how to find online do you have eny place wich i can search and find... I see in one vide you make it by your self the pipes wose lovely...
Im in the process of doing the same thing and when I hit it with the pneumatic impact, it stripped all the threads clean out
Hi I have replaced 2 of the units on my kz1100 and its gone again, any ideas as to whats going on? I replaced the starter clutch with new ones only a month and a half ago and gone again
Are they new replacements or used?
Just did this to my 1100 Goldwing, was an engine out but honestly wasn’t that bad.
Yeah luckily the goldwing isn't too bad to pull. These aren't bad either just sucks that it has to happen
My VFR750 i had to do 2 times, first time was the bearings, the second time the middle part cracked, its common problem with the VFR, i accidentality ordered the wrong bike starter clutch but found the core was the same so after a bit of work and light tacking it worked out real well, its not a bad job on a bike that has it accessible on the side of the engine.
Nice video, did you find the other part of the spring by chance. lol
Thats definitely frustrating. No I did not find the other part of the spring. Who knows how long ago it vanished. I don't think It could cause any damage though being such a soft bit of metal. I assume it would get caught in the pickup at the worst
Not sure if it has been asked already but about how many hours does it take for this repair on the CX-500?
Well this took us probably 4-5 but that was working quickly on an engine I've already had the cover off of so I didn't have to fight rust or stubborn hardware
i adore these vids. I am looking at an 82 cb650 with this issue. I recall you or another youtuber that offered assistance with the honda cb carbs for ultrasonic cleaning. Was that you?
Glad you find the videos helpful. I dont do customer work any longer but you may have asked me for guidance there.
What is the bolt u used to remove the pressed on starter clutch called 3:28 and where can i find one?
That was a "flywheel puller" bolt or stator removal tool. Various names for it. You can find them on motion pro
Ok 👌👍
Well that was pretty amazing. Seems like awful little springs! Such a little part to cause such a big problem and such a major disassembly. Wow. Good job though as usual!
Yeah it's unfortunate that such a small item can cause these issues. Many other bikes the job is much easier
What kind of lube/oil did you use on the springs?
Everything was just engine oil
@@BrickHouseBuilds Thank you
6.24.24. ☝🏼As always…A Superb video🍿
🙏
Can i ask what size is the flywheel puller i have a 82 gl500i
It is an M20x1.5 this article goes over it:
motofaction.org/motorcycles/honda-cx-gl/how-remove-flywheel-honda-cx500-gl500-cx650-gl650/
@@BrickHouseBuilds i used a drain plug same pitch thanks so much for info
Do the rollers ever wear out, since i guess they are in contact with a spinning axle
They can. I've seen more worn starter clutch hubs though.
@@BrickHouseBuilds ok.thx for reply.
what tool did he use to remove the starter clutch basket anyone know ?
That was a flywheel puller. Motion pro makes a bunch of them
@@BrickHouseBuilds is there any specific size for these Honda cx500?
yup my VN 800 got this problem
my mechanic sent me this vid
I like your mechanic 🤘
@@BrickHouseBuilds XD lol was not expecting a response AND so fast
Yeah my Vulcan 800 is sitting there for like almost 2 months now
Changed the battery the charging relay,new oil & filter
He also cleaned the electromotor(not sure that's the right term in english)
And the other day when he tries to start it czcams.com/users/shortsjRmkqMWOqzs
Yesterday he says this might also be problem and shows me this vid
Anyway hope he'll finally manage to get it working,been too long now
Greetings from Romania
P.S. As a joke he said that now he can be aauthorized service on Kawasaki Vulcan 800 XD he worked so much on that bike
In my Honda experience, these clutches usually fail because the ramp piece that the rollers slide up and down on cracks. I've never taken one apart that was acting up that wasn't. I cringed when you didn't pull the cover off to inspect it. Luckily it was a broken spring and not a fracture, it would have been a bitch to put it back in and it still acted up. This is also a chronic problem with KZ650-750's I've probably done close to 10 of those.
This isn't my first rodayoh Michael. Pretty obvious what the issue is.
I might put a crank handle on mine
I found a video last night of a cx500 with a pullstart. Not sure if its real lol
whre is the rest of the spring? (breathing heavily)
Couldn't find it lol. Being a soft material I hope it just got ground up in the trans or is sitting in the oil pickup scree
Why oh why didn't I find this video 300 dollars ago.
It be like that sometimes 😬
Wondering where that half inch of broken spring went to... 🤔
May never know. Its softer so I hope the transmission diced it up
It was all nice and easy then the jack went out 😂 there's a almost always an inconvenience when we plan on doing easy repair
100% of the time in each thing I do I have something like that. I was joking with my friend Seth in the video the entire time about it and got to see it live. Even stuff like the camera not recording made me have to redo scenes 😅
Hopefully my Kawasaki is something similar.
Could I do this without pulling the entire engine out
If it is a cx500/gl500/650 no. You have to remove it
Like and comment :)
😉
Nope, I have a 1982 KZ550 bobber that's make a more horrific sound from the starter clutch. Lol
🤣🤣 well at least you know the fix
@@BrickHouseBuilds Luckily my starter clutch mechanism is all one piece. I don't need to rebuild it, once I get it out of the bike, and its still available. Seems to be a fairlycommon part on a lot of bikes. I just don't understand why Kawasaki would put it in the middle of the engine. Lol
