Aluminum body, NOT cast iron.
Shaft size is 3/4" 11 spline.

This pump replaces bobcat part numbers 6673911and 6672829. It has the 4 bolt flange for the pressure port and was originally used on the following machines.

The older part number 6672829 with O-ring Boss fitting also updates to this pump but requires additional fittings.

There was a problem with the fittings leaking and this new pump resolves this issue by using a 4 bolt mounted fitting instead of the original O-ring type. We can ship these items with the pump if you are converting to this new pump, but it is not included in this sale as most buyers are replacing only rather than upgrading.

This is a standard flow pump, not high flow. If you have high flow, check these links:
