Thanks, Johathan. I don't have the ribbon gauges, but mine are about 4 inches long, so maybe I can do it in at least a couple locations. Looks like another tool purchase...

I did it for years with regular gauges, they will work. Just harder to hang on to.

I got the block back from the shop yesterday and started to reassemble. Got the main bearing, governor and tappets in, then discovered in installing the camshaft that I need a .005 shim. Clearance (side to side play) was .013, spec is .005 to .010. Ordered the shims. That will be next week.

SDD, on your bearing plate shims, the gasket set, if you haven't already got it, should have several shims of different thickness included. The 1450 I did last spring, I had to use 'em all to get the correct clearance.

Did you have your guy check the runout on the ends of your cam with a dial indicator?

I'm on the way to NAPA this AM to drop off another 14HP for machine work.
Keep up the good work!

The gasket set does have the bearing plate shims, but no camshaft shims as far as I could see. The machine shop has not looked at the camshaft. Can you be more specific on the runout measurement?

My machine shop only wants the bare block, they don't do any other work--dis assembly or re assembly.

Another member here had suggested to me that I have that checked as a possible source for the "Kohler Knock" that I have in 2 of my tractors one of which was done last spring and right off the bat has that sound.

"Runout" is a term that basically means warpage. Let me give an example. On the PTO end of the crankshaft, once installed in the engine, you put a dial indicator on the very end of the nose riding on the round part. You then spin the crank with the dial indicator on it and see if the end of the crank is "bent". On most engines there is a runout limit. So, if the runout is .002" and you measured .003" The crankshaft is bent, and would require the nose to be machined.

Now, Kohler does not give a spec on crankshaft runout, and the only spec for the cam is lift, and endplay. I really don't know what you mean finsruskw. Are you saying he should check to see that the cam isn't bent? Or that he needs to check endplay? There is no camshaft runout limit.

Well then, I stand corrected! I'm a retired trucker and not a machinest!!

I feel he meant end play as in the very end of the cam was not square with the horizontal axis and sent pictures of the cam in a lathe w/the dial indicator touching the end.

Sorry if this is not the correct terminoligy

Piston skirt clearance is 6 or 8 mils, Ring end gap measured .015. Waiting on camshaft shims...

mils , are you saying 6 or 8 millimeters or ?
