Other shaft seals
➩ Using a suitable tool, pull the shaft seals from
the bearing seats of the crankshaft, hollow shaft
and shift(Fork)shaft.
➩ Grease the new shaft seals in the region of the
seal lip with Molycote 111.
➩ Insert the shaft seal for the hollow shaft with the
mounting sleeve, as shown in Fig. 37.
◆ Note: Use the Special tool ”Installation tool”
- ROTAX No. 676 022.
Needle and ball bearings
◆ Note: Before the inspection, lubricate the
bearing with engine oil. The inner ring
must be easy and free to turn. The
bearing must not be ‘noisy’..
◆ Note: If the bearing on one side is
damaged, always replace both
bearings.
◆ Note: Where shaft seals are installed
behind the bearings (e.g. hollow
shaft), these should also be replaced
when the bearing is replaced.
➩ Unscrew the vent screw.
➩ Unscrew the oil inspection screw using a
suitable tool (e.g. 20 Cent coin).
◆ Note: Remove the remaining components
on the housing in order to avoid
damage during heating.
➩ Heat up the housing halves with the defective
ball bearings one after the other for 10 minutes
at 150°C.
▲ Warning: When working with oven-heated
components always wear heat
resistant gloves.
