13.3.5) Water pump shaft - removal
See Pic. 115 and 116.
It is an advantage to loosen the impeller already when
dismantling the engine (with crankshaft locked).
Otherwise block water pump drive gear Q with
suitable tool. Unscrew impeller using impeller
wrench 877 295 to avoid damage to the impeller
blades. Place ignition cover on a suitable plain
surface and press water pump shaft out with a
suitable punch W. Remove drive gear Q.
Inspect water pump shaft E for wear. Pay
attention to possible corrosion at the thread
end R. If engine is run without antifreeze,
formation of corrosion is possible in this posi-
tion.
If corroded, replace the water pump shaft.
◆ NOTE: The shaft has a conical end T.
