Removal

Drain Plug, Left (2):

Drain Plug, Right (2):

1 Drain coolant.

CAUTION: The drain plugs (2) are arranged at the left and right of the cylinder crankcase. The lateral crankshaft bearing cap bolts (arrows) should not be confused with the coolant drain plugs.

Installation

CAUTION: When installing a new engine after a previous bearing failure, carefully flush oil hoses, renew oil cooler. Disassemble and clean oil damper.

18 Check engine mounts, coolant, vacuum, oil and fuel hoses, renew if required.

CAUTION: When installing the refrigerant compressor carrier (steel version) it is important to ensure stress-free assembly.
The carrier (steel version) must be checked for distortion. It must rest evenly on all contact points of the cylinder crankcase without gap. This condition should be checked before tightening the bolts.









The bolts must be tightened in the following sequence:
a) Install bolts (17, 6 and 5) finger-tight.
b) Tighten bolts (17) at engine front.
c) Tighten bolt (6) and nut (5) at side of engine.

19 Install and connect engine.
20 Install rear engine mount without tension. Tighten set screw to 30 Nm.
21 Ensure that all drain plugs are tight.
22 Fill in oils (exchange engines and overhauled engines initial operation oil according to Specifications), coolant and refrigerant.
23 Check cooling system for leaks with leak tester. Check antifreeze capacity of coolant.
24 Connect control linkage and check function.
25 Clean air filter and renew if necessary.
26 Clean air cleaner and renew if necessary.
27 Set idle speed and exhaust gas value.
