\'tropical\' water pump pulley.
Hi Guys - not normally on this part of the forum, but maybe someone here can help me. I'm running a Mercedes engine (240D) as a conversion in another 4x4, and I'd like to get the water pump to spin faster, for rockcrawling. I know there was a 'tropical' package available for the 404 series Unimogs with the M180 engine that had a faster ratio for the water pump drive. I also know of the 404 series, 240D powered mogs specced for Angola, so I'd assume that if the gas kit wont work on the diesel, that theres a seperate kit...So far as sedans go, the 220/230 engines have pulleys that cross over to the 240D engines, and I'm guessing that the tropical kit is probably the same.
so - anyone here have a 'tropical' pulley they'd be interested in selling, or have an idea about where/how to buy, or build the requisite smaller pulley? ( or did they change the crank pulley, to make the pump & alternator spin faster ??)
any help, advice, or suggestions would be greatly appreciated.
