Paul,

To pick up on an old thread, it occurred to me the other night that if

one

were to put a set of bearings on the housing under or near the belt

portion of

the pulley, then the bending at the end of the pulley would be

eliminated and

fatigue reduced.

On the stock housing this could be done by notching out the housing,
(providing there is enough material), to allow for a flat fit for the

bearing to sit

on, the bearing to be retained by ring clip, etc.

This also could be done for the water pump housing you have designed.

This would require a newly designed pulley to accomodate the bearing,

however

the revised pulley may be simpler to manufacture in that it would not

have to

be of drawn material.

Because the revised pulley wouldn't have an unsupported end, and both

ends

are supported, alum might work.

Good idea. That pump cartridge and steel pulley is HEAVY!!!!!

Paul &Joe,
I think I suggested this previously - but it was ignored. I though it was
the best solution at the time but may not have the accommodation for the
bearing - but with a new casing and pully, anything is possible.

Sorry George. Do you have the message you sent?
