I have a 450C that I just installed all the clutches in. OUCH If they are similar I can give you some pointers but I am not familiar with a 350C?

Thanks Jim, unfortunately there is not a ton of info on this that I understand and was hoping someone on here might have a bit of experience with these valves. I have looked inside these valves and see very little wear. I believe this pressure might need to be there but would like to understand it a...

Hi, I am installing a thumb on my backhoe and I have "luckily" found an original backhoe control valve that I have installed inline to operate the thumb. I have put everything back together and I pressure checked the entire assembly (7 valves) to see if I have any orings leaking before I install thi...

Hi, just wondering if there was anyone here that has possibly added a thumb to a 450C backhoe attachment and if anyone would have an additional valve to do this that they might want to sell? I am also looking for 14" track pads for this with a bar? Has anyone ever welded Tbar on their pads as well? ...

Hi all, So I have put ALL new clutches in my 450C and what a job. It was obvious that this was tore into before and had not been put together quite right to combine the final sumps. There were a few little ring groves but nothing terrible so I had someone just touch them with a lathe and they turned...

Thanks for the reply. I guess my question would be what is possible to make the pressure drop in gear? I would think even if the HLR discs were worn it would not cause a drop. Is there a hydraulic line inside trans that could cause this OR is something in the valve body itself causing the process to...

Pulling the pins and hoses should be it but it is extremally heavy so dont get a toe in the way. Remove the nose housing and I kept the rad on. I unbolt the bell housing and it should start to slide out. I actually did mine by myself. It sucks but that should tell you how easy it is.

Hi all, I need a little input from the pro's. I have just gotten my stuff back together, new main clutch, cleaned and de-glazed rear steering clutches, etc and I was setting my HLR pressure. At around 1800rpm I seem to have around 160ish psi which seems good but when I go into gear my pressure drops...

Is this a 450B or C??

Hi Jack, I just watched a documentary on the real Jack the ripper (NOT PRETTY) :lol: Even the smartest nut jobs mess up in the end. Last week I just tore down both sides of my 450C and replaced the bands and looked at my clutches. I originally started this project because of the same scenario you ju...

Hi All, Looking for an idea to re-tap the lower mount bolt holes that mounts the backhoe attachment plate on the rear of the tractor. On one side the mounts pulled away and pulled the bolts with it. The last 1/4 of the threads are still there (inner most part) but rest is wallowed out. The holes are...

I just replaced both of mine. Found one side way gone and grinding metal. These adjustments are really time consuming and you need 2 people. When you pull the top plate off you will need to remove the brake adjuster then roll the liner out to see the actual pad.
Good luck

Hi all,

Believe it or not I am now in the middle of rebuilding my battery box on my 450C and had a question, 1-does anyone have a pic they would share of the actual battery plate they sit in?? 2-AL do you have anymore trays and hold downs??

I was going to post some pics for you guys but I can not for the life of me figure out how to do it unless I am not allowed but it shows a pic attachment. Any ideas?

Any discount if i purchase 2??
Do you have 4 of those seals??
