Valve Shimming

[afholderman]

Okay I would like to start off by saying that I do have Steve's valve adjustment sheet, however, there is a problem with the document thinking it is password protected so I can't use it at the moment. With that aside, lets talk shims. I checked my clearances today and here are the results:

Cylinder #; Clearance; Old Shim; New shim

Exhaust

#1 >.04mm; 2.8; 2.7
#2 .05mm; didn't pull
#3 >.04mm; 2.7; 2.65
#4 >.04mm; 2.75; 2.7

Intake

#1 .08mm; didn't pull
#2 >.04mm; 2.7; 2.65
#3 >.04mm; 2.65; 2.6
#4 .05mm; didn't pull

So if my measurements are correct, then I need to trade in a 2.8 and 2.7 for a 2.6 and 2.65 and swap my other shims around. This is my first time doing an adjustment so I just wanted to double check with the more knowledgeable folks on this forum.

If I'm reading this right it doesn't look like you need to do anything. .03-.08 are the tolerances right? I'm in the middle of doing this myself. I hope mine are this good.

Those valves tighter than .04 mm may need to move down two sizes. I'd pull that 2.65 out of 3I and try it in the other locations that are tight so you can get a proper measurement on the sizes you need. As for 3I, when you order shims make sure you have a 2.55 as well as what ever else you need after the measurement. Oh, and don't turn the engine with any shims missing.

good luck

Nessism, good idea with using the thin shim to check the others. Sometimes obvious solutions aren't so obvious.

This is nitpicky but doesn't the symbol you used denote "More Than" .04mm. I think < denotes "Less Than" but I could be wrong.

When you put the new shims in be sure to put them in with the numbers facing the valve..keeps the numbers from being worn off by the cams..little diddy that Rustybronco shared with me ..

D'oh! Didn't catch the greater than/less than signs.

Likewise, I think the tolerances are fine and no shimming is required

The document is password protected, but only for the areas that you are not supposed to be bothering.

Come on, Adler, you haven't noticed anything different in the month that you have had yours, have you?
