sd22-waterpump pulley needed

[crzhors]

Greetings, I need a pulley for the SD22 waterpump. The plot thickens,I've recieved a automotive WP for my Marine style(M4-33) sd22.But the Marine style has a longer shaft and elongated Pulley. Anyone got a spare standard pulley? and then I'll figure how to get it to Panama.

Jeff: I noticed the "deep offset" of your marine pulley but ....
photo angles can be decieving. If there are any automobile junk
yards available to you, it's a -possibility- you'll find a
substitute IF an automotive SD22/SD25 specific pulley cannot be found. The hub demensions might be more common than you think.

I ran across an ebay listing for the SD-33 FORKLIFT water pump. $112 usd. It appears identical respect to the pulley offset ... and the pump housing. Note the greater distance from the flange to the casting compared to the SD22 truck version.
