6. Install crankshaft rear seal:
-
Use standard handle tool No. 999 1801 and assembly tool No. 999 5430, or equivalents.
-
Oil mating surfaces between seating flange and seal, and between seal lips. Place seal on drift.
-
If there are any wear marks on the crankshaft, push seal further into the flange than before by removing a spacer ring from the tool.

Tap seal in until drift meets crankshaft.

Numerical markings on connecting rod must face towards intake side of block (starter motor side).
NOTE:

Pistons, replacement:
Later Volvo 850s have two different types of piston, which differ in terms of the upper compression ring.

Connecting Rods, replacement:
Connecting Rods are symmetrical and can face either way round.

Put the big end in a vice with copper spacers or similar.
Mark both halves with the cylinder number using a number punch or die.

-
Use piston ring pliers tool No. 998 5424, or equivalent.
