Re: low engine oil pressure

Check the coolant level to see if it has gone down. If it has gotten into the engine oil, that might explain the pulsating squirt. Anti freeze doesn't mix with oil and is thin enough to lessen the pressure. It also doesn't lubricate and can cause bearings to spin.

Re: 1010 gas dozer

Just to add to Jim's procedure, be sure the distributor shaft is turning and the points are opening.

Re: JD350 crawler loader engine

I'd recommend cranking the engine over with the valve cover off before running it. You should see that there is oil getting topside. I rebuilt a 350B and took the head to a very reputable machine shop that I've used for years. I got lucky, in a sense, because the injection pump was faulty it wouldn'...

Re: JD 2010c Diesel No Start

Wow Stan!!!
That thing sounds nearly as bad as glow plugs with starting fluid.

Re: 350B pump

Not trying to be a smart a$$ but, you didn't put something up into the suction line, to stop dripping, when you pulled the pump off did you? I known of such getting pushed up into a line out of sight during re-assembly and causing a blockage. Did the drive coupling mesh? Good morning Jim, Found the...

Re: 350B pump

Another silly question---Is there-where is the hydraulic fluid filter for the front pump?(blade reservoir)

350B pump

I had to replace the seal in a 350B dozer hydraulic pump. Turned out to have a 1010 pump on it which, I figure JD was using up left over 1010 pumps. I filled it with fluid and have the proper amount of fluid in the reservoir but, it doesn't pump and it worked fine before it was removed. What did I d...

Re: Engine will not turn over

Sounds like you spun a bearing. Before trying to get it running, you might want to drop the oil pan and take a look. If a bearing is at fault, you could cost yourself a lot more money by running it.

Re: JD450C third head gasket This is getting old

Peace of mind---bite the bullet and replace it. If it grenades, you'll make a mess of your new engine. Think about you've invested. Just my opinion, gregjo1948

Re: JD 2010c Diesel No Start

I'm not sure about the 2010C machines but, when I had a1010C, it was a hard starter. It had glow plugs and a primer also. In the dead of winter I had to resort to starting fluid. (without glow plugs) It's not recommended to use starting fluid on the 1010 or the 2010. I guess it can break the top rin...

Re: hydraulic pump

If it has some oil in it, not washed out and completely dry, it should pull oil through it just fine if you have the reservoir filled to the proper level before starting the engine. The reservoir is above the pump so gravity helps. Just curious on the seal. What was the part number for the one you ...

hydraulic pump

350B dozer w/6way--Replaced the outer shaft seal. I got help here for the part # and called the local JD for availability. Happy to find that it was in stock but, when I got there I found the seal was too large so, I had the parts guy check the seal for a 1010 pump and found it to be the correct siz...

Re: JD350C question

I replaced mine that, I believe, I got from Lavoy. You should take note of the shafts that the coupler is connecting. If the splines are poor on them, it will shorten the life of the coupler. There are a couple reasons why the coupler goes bad. If the housings have loose bolts, allowing the housings...

Re: 350B pump seal

Jim B--WOW!!!! Your knowledge on these old machines amazes me. Between you and Lavoy, seems there's no question you can't answer. I think I need to remeasure this pump I'm working on. I guess I should use the mics instead of my calipers. I got OD 1.112--ID .830--tall/thick .245... I'll measure with ...
