Please Verify that this will fit your machine before purchasing this pump. This is a universal pump so there might be some small changes that need to be done or dealt with. Might need longer bolts to install on engine. the popular size is 5/16 x 3 1/2 and (2) 5/16 x 2 1/2. This would be just standard hardware and spacers that can be purchased at a local store. Also look at the mounting legs to determine if your hose hook up points will match up. They usually mount up fine it just switches the hose hook up point.

Some pumps cover the drain plug on the bottom of the engine but most engines change there oil from the same spot you add to it anymore, so that is not a big issue.
