Still fine tuning a custom mount. This pump is fighting being put on this buggy.................


What pump is it? my understanding was they could not handle the rpm's that the engines turn.

Thats a regular gear pump with Scott's support bearing.
Theoretically gear pumps do not like to be spun fast, but given how long your average rockcrawler will be driven in its life, they have been proven to hold up quite well.

What will happen in the long run is that the gears will wear and the pump will internally bypass (problematic at low rpm).

@Timjus is using one and I beleive he got something like 5 years out of his before changing it.

The support bearing is called an overhung load adapter, common part.

not sure who scott is, but I assume that's a specific one made or modified to mount the automotive ribbed pulley ?
