Valve clearance adjustement, finding the right cranckshaft postion

This is an easy and fast method for valve clearance adjustment, it is about the how and why and a practical method, Works on any four stroke , four cylinder engine.

[@sierushop]

Doing so, identifying 'that notorious moment' in the combustion cycle for Cylinder 1, in which EX valve is closing and IN valve is just opening, allows him to find TDC (on the compression stroke) for Cylinder 4. Then, all he's got to do is to turn exactly 180° the crankshaft pulley to find TDC compression for the remaining cylinders in the order of the firing order of the engine. In this case, after cyl 4, will come cyl 2, then cyl 1, and then cyl 3. Pretty ingenious !

THANK YOU! My husband said this was an excellent video. He never thought about it like this. (he has been doing this for years and never thought of it this way) He is currently working on a N844LT Shibaura motor. Thanks again!! -Phillip & Kirsten

[@rogerdibbens4084]

You come across as having one of the best approaches to life sir. I like to understand how and why. It helps with troubleshooting too. This valve clearance method is probably the best and I used it last night on my Spitfire MkIV. Thank you.

[@wattymolly1926]

sir your chartout firing order is a very helpful scientific formula.

[@D3Sshooter]

Thank you

[@robertobarahonamattas4865]

Finally somebody explain properly.

[@edstimator1]

very thorough explanation. Best one I've seen. Much easier to remember with context.

[@johnculley8648]

Thankyou for making this video. I have used my new found knowledge to adjust the clearances on my old Perkins boat engine and it runs a lot quieter and makes less smoke. Amazingly it also seems to have cured a water leak on the other engine in the boat. You truly are a magician.

[@D3Sshooter]

Glad it helped

[@magdisiam1244]

Fantastic.... Thanks a lot for your explaining on board... It is not a disease but the perfections..... Please can you make the same lesson for 2 cylinder engine..... Firing order is 2....1 where cylinder arrangement 1..2 from flywheel side....... Thx again too much......

[@D3Sshooter]

Thanks for the comments

[@ROAlexa1981]

All this for understanding that all the valves must be closed wen you adjust the valve clearance on one cylinder and the motor must be cold...the most important things.
A good method if you do not a another. Stay to one method if already now one or stay on this one if you learn this one, do not mix them ! Good explanation, i can see that you know very well how an engine works !
All the beast !

[@D3Sshooter]

ROAlexa1981 txs for the comments, and yes you are right. I have tried here to give an explantion why we do the things the way we do. . For those who like to get an in depth understanding. Of course one can adjust valves without knowing all this. However IMO understanding why is as importend as the how . Have a great day. Txs again for your comments

[@D3Sshooter]

ROAlexa1981 txs for the comments. Indeed the how is one element and can be enough. However IMO , the why is as important and helps for a better understanding from which people can develop their own methods.

[@classicvolvorestorations3848]

The Volvo B18 and B20 method you rotate to TDC, half valves will be loose so set those, rotate 360 degrees and other half will be loose so set these.

[@tracyoliver550]

Great job on the video! I have factory markings on my flywheel, both 1/4 and 2/3, but when aligned the rockers are not at their most “relaxed” position. I have to rotate a few degrees further to get them there. If I adjust at the markings, the clearance would be huge when the rocker reaches its highest lift. Suggestions? Ignore the factory markings?

[@thintheherd8891]

Love your videos. I've learned more in three videos than I have in the past month by reading about my tractor. Just bought a Massey furguson 25 and gonna restore it. Great videos!👍

[@lasource811]

After watching a lot of videos yours finally explained the twenty or so questions I was having so perfectly. Great job. Subbed so I can watch more of your videos.
Two question though if you dont mind. My tractor is a two cylinder, you mentioned this would only work on a four cylinder. Why would it not also work on a two, as it is half the cylinders. Also it being a diesel means it is a four stroke, no oils added to the fuel, would that be correct.

[@lasource811]

Ah now i see why it only works on four cylinders. After thinking about it a bit more. it is because on four cylinders at the point where you see the out and intake valve being in the correct position on a two cylinder engine, cylinder number two would be in the wrong position for addjustment. Maybe spinning a full turn, instead of a half turn; what do you think. Great method.

[@TAXOPAREI]

excellent presentation and thank you for your effort, for first time i did this job on my one tractor engine I completely adjust my three-cylinder engine in a different way, I turned the crank until both valves of each cylinder were closed, is this wrong ?

[@bluefallon6374]

Please do a video on a 3 cylinder diesel with no TDC marks.

fyi . I just checked and adjusted valves on CASE1294 .
over 4000 hours on engine . all were 0.009 to .013"
a clean engine , but the fan belt was very worn and pulleys do Not line up Exactly. 😕
a new lift fuel pump and glow/preheater will be added.

[@WilliamMcGurk-j3j]

Thanks for the excellent explanation, but i must still be missing something. Why can't you adjust cylinders 1 &4, rotate half a turn, and then adjust 3 & 2? The cylinders are in their top positions regardless of whether you're finishing the compression stroke or the exhaust stronke... right?

[@itsgonnarain100]

if you have cylinder 1 on TDC why dont you set cylinder 1 valves ? why set NO.4 when NO.1 is TDC? if NO.1 is TDC then the both valves on NO.1 are closed, right.

@@D3Sshooter thank you

[@garED1678]

Sir, how about 6 to 8 cylinder firing order?

[@D3Sshooter]

Its the same method, 2 full crankshaft rotations to fire all 6 or 8 pistons, so 720 degrees / 6 = 120 degrees one cylinder fires for an 8 cylinder that is 90 degrees
