24) After removing the C-clip (33B), pry out seal adapter (33) with a screwdriver.
25) Check seals (32) and surfaces of plunger base (25).
26) Remove crankcase cover (4). Loosen inner hexagon screws (24A) on the connecting rods (24) and push con rod halves

as far into the crosshead guide as possible.

CAUTION: Connecting rods (24) are marked for identification. Do not twist connecting rod halves. Connecting

rod is to be reinstalled in the same position on crankshaft journals.

27) Check surfaces of the connecting rod (24) and crankshaft (22).
28) Take out bearing cover (14) to one side and push out crankshaft (22) taking particular care that the connecting rod (24)

doesn’t bend.

29) Reassemble in reverse order: Regulate axial bearing clearance - minimum 0.1mm, maximum 0.15mm-by means of fitting

disc (20A). The crankshaft (22) should turn easily with little clearance. Tighten inner hexagon screws (24A) to 30 ft.-lbs.

CAUTION: Connecting rod (24) has to be able to be slightly moved sidewise at the stroke journals.

30) Reassemble cover (4) and seal (5) onto crankcase (1). Fasten with hexagon screws (10).
31) Reinstall shim (33C), and seal adapter (33) with radial shaft seal (32), and o-ring (33A) onto crankcase (1).

CAUTION: Radial shaft seal (32) must always be installed so that the seal-lip on the inside diameter faces the oil.

32) Reinstall remainder of fluid end as described above.
