I'd be looking at the small screen in the return to the injection pump. If the governor ring goes, it plugs up that screen leans out the engine (rev up) and then it cant start.
You might pull the timing cover on the injection pump and hold a rag under see if you have governor ring pieces there.

Re: JD350 Broken Crossbar Bolt Replacement
Nice repair work ! I almost always have to throw quite a bit of heat at the broke bolt to get them to spin out. They can be a real pain.

Re: model c roosamaster injection pump leaking fuel at throttle pinion lever.
I will second it's better to send them off and have the whole unit rebuilt. All the seals are the same age as the one that is leaking...

Re: 450C steering clutches oil
Yes, the screen is at the bottom of the sump. It's going to be alot of oil be prepared to catch all that.

Re: 450C steering clutches oil
Mine does not have common sump. I have to check all three separately. Most people seem to suggest if the fill plug is removable ie not lock tighted in they do not have the common sump done.

Re: Trans fluid draining into final drive
Sounds to me like the bottom port of the common sump is plugged not allowing fluid to drain back.

Re: JD350B Brakes
Is there any chance this is just a really weak motor? Doesn't have the power to turn both sides? I guess i'm trying to think outside the box here.

Re: 450b capacty data and spec sheet
I think the 450b will be more like the 450c than the 450's. Are you looking for something specific ?

Re: 450c needs a squirt of ether to start then runs and starts fine
Mine is the exact same way even after having the injection pump rebuilt. Been that way the entire time I've owned it. I know I need to rebuild the motor as it has low oil pressure (but enough) I assume it's a lack of compression causing the issue but I certainly do not know for sure. The people on t...

Re: Need help hydraulic oil
As stated that will probably work in the hydraulic system but you should not run that in the HLR. You will have to keep 2 oils around, which no one likes to do that is why most of us run a hydraulic/transmission oil in everything. I purchase mine in bulk 55 gallon barrels from Petrochoice and save a...

Re: John Deere 450b
If it's like my 450c the oil pressure sending unit is right rear of engine. It should have a filter in the tank yes, you'll have to open the top of the tank to service it. Mine had fallen off and was in the bottom of the tank.

Re: 350c thrown track
Probably so, if it's an original style adjuster, remember you do not need to take the bolt all the way out just loosen it till grease starts to flow out the hole. Then you are less likely to loose the BB.

Re: 350B injection pump rebuilder
I highly recommend "thepumpguysc" from the heavy equipment forums. You can send him a message with what your have and he's very responsive, I had my pump back in less than 10 days total.
