JD 1830 hydraulic pump connector

[Krocker]

Hello. This is my first time trying to post something, Hopefully I can do it. I am wondering if anyone can advise me. I have a John Deere 1830 Loader tractor. The bushings wore between the Crankshaft pulley and the hydraulic pump. So I got new bushings and bolts. The bolt holes in the pulley were ob long. so I noticed two other bolt holes in the pulley. But if I use them the bushings won`t line up with the bushings on the pump. If I had a coupler that took the 4 1/2 inch spread bushings of the crank pulley and could connect with the 3 1/2 inch spread bushings on the pump, I would be good to go. Anyone know if they make such an animal

JD had 2 different size(length) clamps intended for 2 different size hyd pumps. I don't know if the larger could improvised too work or not if your tractor hasd the smaller ones.

I'd replace or repair the pulley. Maybe have a machine shop drill and tap a new set of holes 45 degrees from the current set if they could not be fixed.

Thanks. I modifyied the old clamp to get me by for now and she is working good. Maybe in winter I'll seperate the tractor and change the pulley. The tractor is 40 years old I can't be the first one to try this.
