A couple of years ago I bought a 300B backhoe. It had been sitting in the guys pasture for 2-3 years. We dragged it back to the shop and tried to start it. No luck. So I did a compression check. 100-0-300 psi. No good. So I ordered a in-frame rebuild kit, installed it and did a valve job...
The tractor recently refuses to run. It started off staying running for only about a minute and cant throttle or anything. Then it would stall out. Now it will not run at all. Changed fuel filter and fuel pump. Cleaned out the injectors. Next thing I can think of would be the Injection Pump...
Hello to all,
I have a 1983 JD300B with 3pt hitch that will lift implements but will often need to be jerked or manually helped to do so. I looked through the Hydraulic fill cap hole and can see spraying oil from the top, if I jerk the lift harms manually,the implement lifts very well and the...
Where could I find this hose, or what could i use? I can not seem to find low pressure hydraulic lines and I do not want to leave my system drained for days.
Thanks!
Hi, I am new here, at least as a member. Have been following this site for years and it has been very educational and there is a lot of knowledge base.
My issue again is with the hydraulics of a 300B with loader and backhoe. I have read the previous posts, followed the advice and learned a lot...
Searching for information for a friend. Looking for a manual for a 300B specifically how to replace the transmission filters. He took them off and doesn't know the order to replace the screws and other parts. If anyone can direct us to a resource it would be greatly appreciated.
Im having intermediate loss of hyd pressure for the loader and hoe. Cleaned suction screen, changed fluid. I understand the Pressure Control Valve (AR65882) can cause my problem and have removed it and cleaned it. Inside there is a cup shaped part that the parts manual calls an orifice, however...
Hello all !!!
Last month I bought a 70's vintage John Deere 300b tractor with a loader and a cab. After 1/2 hour of using it, the hydraulics start to shutter. If I let it rest for 10 min it will start to work again. I have changed the hydraulic oil and both filters. I also (watched a...
I have a 300b john deere that has always seemed to have a slow loader, boom up and tilt atleast. I have noticed that the first time I start it after its been sitting for a couple days if I raise the loader as soon as it starts it raises very fast. after the first time it hits its stand-by...
Hello everyone. I am new member who could use some advice. I have a 1972 JD 300b backhoe diesel that has a starting issue. When it sits for a day or so it starts right up after running it if I shut it down it barely turns over and will not turn fast enough to start. Battery voltage checks...
Hi I have a 1980 john deere 300b backhoe/loader. The hydraulics only work at full rpm and are somewhat slow.....I was told the pump sounded good. I am lost and need some help figuring out why the hydraulics are acting up. This is not just the loader, it is the backhoe and power steering. Once...

Has anyone found a good source for loader pins for a 1974 John Deere 300D Industrial tractor? I have a part number out of the manual but nothing comes up when Goggled. Mine are shot. Thanks.# AU42550 Loader bucket pins.
My father-in-law just bought a old John Deere 300B backhoe/loader, he figures its a 70's vintage. Interestingly enough it might even be one he helped build when he was at John Deere Dubuque Works many years ago. This one is a project, but he was able to get it started and drive it the 10 miles...

Have recently inherited an older JD300B w/ loader, no backhoe but does have 3 pt hitch. When running, I can hear a noise from the hyd pump in the front when NOT under load. I'm not a mechanic so all help will be appreciated.
Put under load and noise goes away.
W/ load or not, the 3 pt will...
I was on the other day asking about these hydra. issuse I have. Somone said to see if any valves are getting hot. The line and valve going to the front bucket gets alittle warm the rest are cold. I guess this could be my internal leak. I have two questions. Is the front loader valve a closed...

I own a 1970 300B John Deere. Last week, the front axle broke off where the kingpin joins into the axle.
I can't seem to find an axle for it in South Africa (out of production at John Deere) and I'm thinking of importing a second hand front axle for the 300B...
