 CAUTION 

Improper gear lash can cause damage to the gear train and the lubricating oil pump.

Shims will be available in six different thicknesses in order to provide correct lash. The various thicknesses are identified by the color of the shim. Identify the number stamped on the pump (1) and the letter on the block (2). Use the following table to determine which shim should be used according to the stamped number and letter.

If a lube pump or cylinder block is replaced, the block and pump will not be stamped. In that instance, a shim must be chosen and installed. The oil pump idler gear backlash must be checked. If the backlash is not within the specification, choose another size shim and recheck the backlash. Do this until the backlash is within specification.

If the lubricating oil pump is not within specifications, the shims must be changed to proper thickness to give proper backlash.
