Skandic LT 443 Engine Type
To check proper clearance between bearing no. 3
and crankshaft counterbalance, use feeler gauge
(P/N 420 876 620).
Mount second bearing with distance gauge
(P/N 420 876 822) for 443 for proper positioning.

2. Distance gauge
Prior to installation, heat the bearing as per the
procedure given further in this subsection.
This will expand bearings and ease installation. In-
stall bearings with groove as per exploded view.
Skandic WT/SWT/SUV 552 Engine Type
Heat up the bearing(s) using bearing heater (P/N 529
035 969). This will expand bearings and ease instal-
lation. If required, put a suitable plate or shim to avoid
the direct contact between integrated seal and the
heating surface.
CAUTION: Bearing should not be heated to
more than 80°C (176°F). Do not heat bearing with
direct flame or heat gun or heated oil. Inappro-
priate heating procedure(s) may cause inner seal
failure.
Turn bearing(s) several times during heating pro-
cess for heating it/them properly.
NOTE: Normally it takes approximately 10 min-
utes to heat up a bearing. So in the event of replac-
ing a bearing, it is recommended to start heating
it prior to removal. Two bearings can be heated at
the same time on one bearing heater.
1. Bearings
Touch the inner race of the bearing with the tem-
perature indicator stick (P/N 529 035 970). Stick
will liquefy when the bearing reaches the proper
temperature.
