Small end bush

To remove and to fit
Cautions:
l Do not use a reamer - specialist equipment and personnel with the correct training are needed to machine
the partially finished small end bush. For further information refer to the Technical Service Department,
Perkins Engines, Peterborough, England.
l Do not use a letter stamp to mark the connecting rod. The new letter must be engraved onto the big-end of
the connecting rod.
Clean the parent bore of the connecting rod and remove any sharp edges.
Press in the service bush, part number 3112E008.
Ensure that the lubrication hole in the bush is on the same side as, and is aligned with, the hole in the top of
the connecting rod. Machine the bush.
To obtain the correct connecting rod grade, refer to Operation 4-10.
The surface finish of the bush is RA 0,8 micro-meters, all other dimensions are given in the relevant Data and
dimensions for "Pistons and connecting rods" on page 20.
