Hello all,
I am the relatively new owner of a wonderful old
Allied Seawind 2 equipped with the "mighty" W30. After stamping out a few demons associated with the
Balmar alternator consuming belts at a prodigious rate, I am left with one more
engine room
project. That being the alignment of the
raw water pulley with the crank sheave. No matter how I approach this, I can't achieve better than a 3/16 parallel offset alignment between the crank and the
Jabsco water pump pulley. Angular alignment is good. Since the mounting bracket for the
water pump itself is non adjustable, the only way I see to achieve proper alignment is to runout the pulley on the
water pump shaft--which then leads to the pulley bore being no longer completely on the shaft.
The belt manufacturers, namely Gates indicates in their engineering documents that this amount of difference is within limits, but I am still generating some dust in this area as a result. Does anyone have any ideas concerning alternate pulleys that might be available?
Thanks
