We're moving a 400 series loader from one D17 without power steering to another D17 with power steering. The problem I'm having is that the D17 we're moving the loader to has a stand alone power steering pump that is run off a second belt from the main pulley. Since the main pulley is set up for 2 belts, there's no clearance for us to mount up the casting the shaft slides into to run the loader hydraulic pump off the front of the engine. The casting is a 4 bolt set up and there are only 3 holes tapped into the main pulley. Has anyone else ran into this same scenario and is there a different casting that Allis made that is a minimum clearance for this type of set up?

3-hole pulley is from a Gleaner combine engine, not a tractor.

Good luck your going to need it. The frist time was a pain time two we switched engines from a gleaner. we also switched pullys.

Sounds like you'll have to either change some parts around to get the proper pulley down there, or make a custom coupler with 3-hole pattern.

Making these things isn't difficult, as long as you have a metal lathe and some various materials available. If not, you're kinda stuck.

The Gleaner 3 bolt coupler uses a left hand thread shaft to drive the pump. Get the shaft and the coupler.

There's not room for the combine parts....front support is in the way......drive coupler has to be countersunk in the pulley.

Priced a new pulley, coupler and hydraulic pump shaft from Agco today....almost $1100 for all 3! $457 just for the pulley...wow.
