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.
7. Assemble pistons and connecting rods:
Arrow on piston crown must point towards front, i.e. timing belt, end of engine.
Numerical markings on connecting rod must face towards intake side of block (starter motor side).
Install wrist pin circlip and check that the circlip springs apart and locks in the groove.
The circlip opening should point downwards.
Later Volvo 850s have two different types of piston, which differ in terms of the upper compression ring.
Version number 1 can be replaced by version number 2 without having to replace all the pistons; but version number 2 can not be replaced
by version number 1.
Connecting Rods, replacement:
Connecting Rods are symmetrical and can face either way round.
Assemble connecting rod (tighten bolts to 20 Nm) and check that bearing end cap is pointing the right way.
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.
8. Install piston rings as follows:
Use piston ring pliers tool No. 998 5424, or equivalent.
Turn rings so gaps are approx. 120° apart.
