what is the difference internally between a std weiand 177 and the merc 525sc version ? I know the pulley is different and the case is for a 4500 carb, but looking for a shaft, bearings, etc, thanks Rob

I rebuilt my merc 525sc blowers with 177 parts. I installed the keyed shafts so I could get pulleys in various sizes. Bearings are run of the mill which I got at a local bearing house, gaskets I got off an ebay site. Everything else from jegs/summit.

Do the std 177 automotive blowers have an oil resovior on the rear or are they sealed bearings?

what year were yours ?? seems they made 3 different blowers with different lenth shafts, and only the 9.9 lenth shaft is available now...so this does not look good....Rob
