measurements show 2 cam shims per side

[hcoles]

Hello Folks,
Now measuring for cam shim check. Is it unusual to have the calculations come out to two shims to be added per side. Motor has 77k miles. As I recall the gears had wear patterns on the front of the car side which makes sense. If someone replies I'll go recount the number of shims that were there when the motor came apart if needed.

I'm using a new Stomski tool and a digital caliper and taking readings a bunch of times until I get good and consistant at it and then taking an average with the Stomski bar flipped one way and then the other. I think the bar is straight however as I put it on the granite block at work and no gaps.

Thanks,

-Henry

I have an excel spread sheet with a diagram and data but I don't know how to attach it...

That tool is great isn't it? I would try measuring with another caliper. I've measured less than a dozen motors but every one of them had (or should have had!) 3 shims on the left and 4 on the right.

Chris,

After checking my math again and remeasuring and remeasuring I think I'm back to the same number of shims that were in there to start with. I still need to count them. I'm about tired of this for today. The Stomski tool works very well as you say. In Wayne's book the shims are described as 0.25mm thick on page 159 but all the ones I bought and were in the engine are about 0.51mm or so.

Thanks for the reply. This situation seems about resolved...now on to the next one.

after all the measuring and fussing around I finally got my measurement technique improved and triple checked and ended up with 3 on the left and 4 on the right and this put me inside the +/-0.25mm tolerance. I used the Stomski tool and a digital caliper, in addition I measured flipping the Stomski bar and also turning the cams 90 degress for each measurement set, this gives 8 readings per side and was used to get the average. If you have done this you know how careful you need to be....it is easy to get measurments that are .2 to .3mm off and this will mess up the average measurement. I made a spread sheet that can be used, send me an email and I'll send it back, includes a diagram with the numbers in Waynes book and shows how the numbers all add up/etc. If Wayne wants he can have it as a submission to the tech. notes entries.
