[AJD] Model B Rod Torque

[bill gray]

Bill ,
  Thanks for the input. The Shims are laminated with .003" thick wafers. I will try to get the other dimentions tomorrow. 
  I thought the same as you, when I removed the rods I was prepared to remove some of the shims but when I checked the fit with Plastigage I found the gap was nearer .002 than .003 on the # 1 piston rod.  The fit on #2 was good.  I purchased this tractor last year and it was obvious that it had had some engine work in  the past.  I can only assume some if the shims had been removed at that time.
   
  Unfortunately I have had to go further into the engine than I had planned.  I only planned to replace the manifold, the muffler, and the airstack.  The previous owner had cut the flange off of the manifold and mounted a muffler with a coupling such that it pointed down towards the ground and the airstack had been broken off.  In the process of replacing the manifold I broke off several bolts so I removed the head for repair. Then I noticed the block attachment bolts were loose so I removed it and found the gasket was shot (the reason for sgnificant oil deposits on top of the engine I assume).  I then found the block needed boring so I am now into a total engine rebuild. Such is life with old tractors!

I've never had the need for more shims, since as engines wear you take shims
out, not put more in. I bought a whole box of shims years ago at an
auction. If you send me a picture and dimensions maybe I have what you
need.

Bill,

According to my IT manual; the torque should be 62.5 ft-lb. 

I think shims are still available from Deere. Sometimes you can find them
on ebay. The fastest and probably the cheapest place is a tractor salvage
yard.

I am in the process of reassembling a John Deere 1950 model B that still has
the babbitted rods. Does anyone know what the torque should be on the rod
bolts? Also I am looking for a source of shims for the rods. Any help
would be appreciated.
