Re: JD440 gasser steering clutch drama.

With that much money spent, you could have bought a working JD 350. For a shop that should have all the knowledge and tools to repair a machine like that, they certainly over charged you. I don't know how they can justify those ridiculous fees. I took the head from my 350B to a local machine shop an...

Re: Missing voltage regulator on my JD 450C

Delco-Remy alternators can have an internal regulator.

Re: JD 450 crawler won't stay running

It's sad that a machine that size is rendered disable from a $30.00 part. Good luck rebuilding the pump. If it's your first pump rebuild, pay very close attention to how it's disassembled. There are about 1,000,000 parts in there and they seem to need to be reinstalled properly. I've gotten to the ...

Re: New 450B purchase, worth it?

Probably the backhoe runs off the hydraulic pump which, I think is at the front of the machine.(it is on my 350B)

If the check valve solves the short term problem, it's not the long term solution.
Why do you think it's not the "long term solution"?

Re: JD 450 crawler won't stay running

I had a JD 300B diesel tractor that would start and run a few minutes then quit. Turn out to be a faulty check valve on the return line going into the injection pump. It's just a little fitting just before the pump that has a little ball inside. Don't know if your 450 has it but, it's worth a look. ...

Re: 350 Steering clutch driveshaft

Can you see any marks where the washers have rubbed. If so, I'd think maybe someone did install them as spacers. If you've replaced bearings and races, you shouldn't need to put the washers/spacers in.

Re: John Deere 350b reverse problems

I would say the problem is with the reverser flow accumulator. If I remember correctly,this is mounted on the left side of the reverser housing and I don't think it can be removed without removing the reverser housing.I don't remember for sure but, I don't think there is room enough to remove the mo...

Re: Replacing cylinder liners cracked block

Did you follow the correct torque sequence? Seams like coolant would follow the cracks down to the oil pan. The crack to the bolt hole will allow coolant to the bolt hole and try to get up into the top of the head and then to the oil pan. Maybe if some sealant is applied to the head bolt, it would s...

Re: Tough time with JD 420 transmission or clutch, or who knows?

I'd pull it back apart to the point where you could move the wheels by hand with the shaft. Apply the brakes. block the wheels, keep the machine from rolling and try turning that shaft again. If the shaft turns, start looking into where it stops turning. If the shaft won't turn, then look at reverse...
