Re: New hydraulic pump and now a pressure question

Yes 77Ford, the pump up front. The splines were worn to a knife edge and ready to wipe away.

Re: New hydraulic pump and now a pressure question

Oh boy.... This is why forums are so valuable. I apparently had no idea. Yeah a little embarrassing but if I don't ask, I won't learn. So I have not had a chance to check the pressure at the 1500 RPM range. I was getting prepared to add the shim or penny to boost it up some if it is low. I know it u...

Re: New hydraulic pump and now a pressure question

Thank you Bruce. I appreciate the info. If it is in the manual I missed it. Glad the parts are working well for you. I enjoyed making them. Could not have done it without you and Stan. :)

New hydraulic pump and now a pressure question

Crawler is a 1975 JD450CJ with 6 way blade. I have replaced the 4219 engine with an upgraded 4239 as detailed in the 3rd head gasket thread. While I had it apart I found the hydraulic pump had bad splines, close to wiping them clean off the shaft. The old pump made good pressure. I made sure to get ...

Re: JD450C third head gasket This is getting old

Thank you. The engine project quickly snowballed into a very expensive set of apologies to the wife for promising to keep it under 4 grand. I went way past double that. I fired it up a couple months ago while everything was under snow and ice. I wanted to rotate a shipping container to reposition it...

Re: JD450C third head gasket This is getting old

Track man Spokane Wa. Nice folks. I would have to find the file for the price. 500ish? It is built better than the one that is coming off. I need to change it out. The track pin removal is keeping me from proceeding. That and a truck build occupying the shop space needed to wrestle with the machine....

Re: JD450C third head gasket This is getting old

I want to apologize to the folks that have sent me PM's. I have not been back in a while and assumed I would get an email notification when a PM came through. Not so, I will check back more frequently. I have sent out responses and again, sorry... I will be back with more 450C projects this summer. ...

Re: JD450C third head gasket This is getting old

Funny, I just wandered into this site to see what was up. I was surprised to see this build thread on the front page. I enjoyed the build. It still starts with less than a full revolution. I have only put about two hours on it since getting it running. It is under a tarp next to my old JD400 backhoe...

Re: 450C how to bar over engine?

I had the hyd pump drive off for my rebuild. I bought a cheap 13? spline shaft and cut it short. Then welded a very large nut on it. Easy quick and now I can turn the engine over with a wrench. As long as the pump spline drive is off and out of the way. I think there is a picture of it in my long 3r...

Re: JD450C third head gasket This is getting old

They don't want to move easily. Mine were a regular tug O war too. I am sure you probably saw what I made to get the liners out. I have a drawer with several crawler specific tools in it now. Most custom made and a couple bought ones. I will probably never use them again. :mrgreen: I better go knock...

Re: JD450C third head gasket This is getting old

Thanks guys.. I wish I did not have so much on my plate. I would like to get after the brakes and check the steering clutches. I see in the notes from two owners ago had issues adjusting the left brake. Probably issues in there. But the crawler just purrs and starts instantly. I will do some work wi...

Re: JD450C third head gasket This is getting old

I finally got to use my crawler after a full winter of rebuilding everything forward of the key switch. The motor did not even get a full revolution before firing off. It purrs and is amazing compared to what it used to do. After a pretty disappointing experience (again) with Stewart Warner I can sa...

Re: JD450C third head gasket This is getting old

Well I wanted to post a follow up. My Stewart Warner gauges have failed. The IGN post was grounding out to the dash and only when the terminal nut was tight. That kept me busy for a bit to find that. With yet another set of gauges with crooked faces crimped in position, I decided that I am done with...
