Piston: Service and Repair

Fig. 31 Piston & rod assembly:

Assemble pistons to connecting rods as shown in Fig. 31.

PISTONS
A .001 inch oversize piston is available for service use so that proper clearances can be obtained for slightly worn cylinder bores requiring only light honing. In addition, oversizes of .020 inch, .030 inch and .040 inch are available. If the cylinders have less than .005 inch taper or wear, they can be reconditioned with a hone and fitted with the .001 inch oversize piston.

ROD BEARINGS
Connecting rod bearing inserts are available in standard size and undersizes of .001 inch, .002 inch, .010 inch and .020 inch. The bearings can be replaced without removing the rod assembly by removing the cap and replacing the upper and lower halves of the bearing.
