Cam Sprocket Shims
Anyone have a spare shim or two they'd be willing to mail to me in an envelope? I just checked sprocket alignment and I'm .51mm shy on the right side. I'd hate to have to place an order just for two shims....
 Mike...

Tom,
Rechecked measurements this morning and came to realization that I need to remove, not add shims...  . Thx for your offer to help though. As others have already said on other threads, you're a great guy....  Mike...

If you have 3 on the left and 4 on the right, you're motor is sprocket alignment is probably good. What was your measurement technique?

Chris,
I actually started with 5 on the left side and 4 on the right based on what was in there previously. Followed the procedure in Wayne's book and determined that I had to remove one on the right side. Rechecked measurements several times to confirm. Installed new intermediate shaft sprockets and sent the cams out to be reground, so I couldn't assume the original shim stacks were correct. Also, noticed signs of misalignment wear on the back side of the right hand sprocket, further confirming the measurements. Mike...

Little known fact (at least I didn't used to know), the shims are the same as the ones on your alternator pully.

I did a little digging and they are the same part number for a '73 but somewhere along the line the fan shim got a different part number. I checked '83 and an '87 901 105 561 00 for the cam shim 930 106 564 00 for the fan shim I wonder if the fan shim changed dimensions at some point? -Chris

HI Chris
the shim has changed on the outside, it is smaller to fit in the double pulley on the SC fan. regards mike

Since we are talking cam shims...
During my recent rebuild on a stock '75 (911/44) I found that my shims were 0.5 mm thick. Wayne's book described them as being 0.25 mm thick. Is this a unique abberancy? I also noted that the thrust washers were of slightly different thickness - (3.9 vs 4.0 mm or something like that) presumably to allow finer cam alighnment adjustment?
