Installing hydraulic pump

After installing 2 or 3 hydraulic pumps I finely got smarter and cut a couple bolt heads off for studs in order to align the pump to the engine. That makes it a lot easier to install the bolts.

Has anyone welded the two back motor mount bolts to the frame? Seems like a easy way to install the nuts on the bolts. I have had a hard time holding the bolt in place then using wrench to tighten the nuts. :weld1:

I don't know about welding the bolts in.. The Loaders - 646 are so totally different from the 300 - 400's. But in the case of my 646 I put helicoils into the holes in the frame, which is about 3/8" thick on a 646 so I can run the bolts in without nuts on the bottom on them..

How about welding nuts under the frame and run the bolts in from the top? :peace: Harry

That would work also. The only problem is the clearance on the flywheel shout.
I'm going to try both ways later and let you know how it goes.
