I’ve seen videos quoting the “rule of 9” for a 4-cyl, 4-stroke engine - when valve 8 is fully open, adjust 1, when 7 is fully open, adjust 2, and so on.

I'm amazed someone is working on a zetor errr, bobcat tractor that I can comprehend. Good stuff.

I hold the pushrod down as I rotate to make sure it's all the way down. If your marks are off the pushrod won't be all the way. Never trust timing marks especially on a motor with a harmonic balancer

[gogogeedus]

This is the method recommended by manufacturers because it's a time saving method.

[marsvanesch]

thank you, i realy enjoy the way you explain this

It's best to final adjust when engine is hot.

[mikegoodman]

The technically correct way to do it is to set the intake valve when the exhaust valve just starts to open, and the exhaust valve when the intake valve just starts to close. The lifter is on the base circle of the cam which is EXACTLY where you want to set the clearance. Only a hack would set it your way. As always do it like the manufacturer recommends if you don't know any better. If you did it your way on a MACk with a "Jake" brake you would be in for rude awakening.

Hello is the same method for a c3.3b cat engine?

[IsleOfFeldspar]

I just did my old 3-cyl kubota and oddly 2 of them were out of spec loose (.33 mm instead of .2) but the other four were tight! How could four of them have no clearance after 42 years and 1500 hours? I don’t get it, but I backed them off until all 6 were .2 mm. I turned the crank through multiple full strokes to make sure none of them exceeded.2 at any point.

Is it ok to set tappet loose after a fresh engine rebuild? the idea is to let valve seat to adjust properly cause they were built new too.

Have You Got To Re Torque The Cylinder Head Bolts/Nuts On That Engine After Its Been Run ?

[arinzeuzoma]

Please I thought that the inlet and outlet valve are meant to bear different adjustment

[tebogobaloyi]

So the correct measurement is 0.25m on the filigage?

[kelvinbridglal]

Does the intake and exhaust valves carry the same clearance?
Thought the exhaust valves carries a larger clearance than the intake.

[tangowiskey]

Why not just roll the engine over in firing order and adjust ?

[ChrispineMusumali-vh]

So when you set cylinder 1do we need to turn the engine set 3

How to adjust cylinder number three on diesel engine four cylinders

[philiplewis]

Great video, very informative! How much torque did you apply to the head bolts? We have been recommended 20kgm
