Kirk,
Checking my mail this morning it looks like no one has responded to your
questions so I'll give you the "benefit" of my meager knowledge on the
subject.
Water pump and radiator are common to all multifuel M35's.
The water pump consists of a housing that bolts to the block, a cartridge
type bearing, a flange for mounting the fan , a seal to keep coolant from
leaking out, and an impeller for pumping the coolant. The impeller is
pretty much bullet proof. The seal presses into the housing and has a
spring loaded element that presses against a polished surface on the
impeller and a rubber bellows forming a seal to prevent coolant from
leaking
out. If the seal is bad coolant will leak past the seal and out through a
weep hole in the bottom of the housing. Coolant may also get into the
bearing and destroy it. Check to see if coolant has been leaking out the
weep hole. If it has, replace it.
The bearings are sealed for "life". No provision for lubrication. To check
the bearings, grab the fan blade and try to wiggle it to see if there is
any
play in the bearings. If there is, replace it.
New water pumps aren't too hard to find or a competent repair shop should
be
able to rebuild your old one with new bearings and seal (could be more
expensive than a new one).
Hope this helps. Good luck.
