JD60 no oil pressure

garyedward · Apr 19, 2022

I Started my JD60 during a cold spell last month and had no oil pressure. Discovered ice in the crank case. I cleaned it out, changed the filter and added new oil. Now,I do not have any pressure in the line going to the gas shut off or the pressure gauge. How can I check if the pump is bad without tearing everything apart. Any advice is welcomed. There are no 2 cylinder mechanics left anymore around my neck of the woods so I'm on my own with limited skills.

I hand started a 37A one frosty morning and had a catch in it, stopping the flywheel, so I backed up the flywheel and gave it a real twist and it turned just fine and started. Drove it to the high school ag shop 12 miles away...at its leisurely top gear.

Come to find out, I had broken the coupling driving the oil pump in the crankcase! It amazes me why that engine did not seize, leaving me stranded on the road that cold morning. Leo

Most likely, the coupler that connects the pump drive to the oil pump shaft is broken. You will need a service manual and a helper. The coupling that you will probably need is B250.

Pull the top cover & you will see the coupling is gone that drives the pump.

Not a Put put guy. Why not with ign. off take oil line off gauge at block and spin it over you should get oil spurting out if not then deeper in to it.

Leo,My niece married a civil engineer,they own a Ranchette,kids and all,so he bought a 450 IHC gas,my brother went threw it all and changed the fluids etc,and hauled it out there,so my brother and wife went out to visit one time, he tells my brother to go get the 450 and hook on to such ans such,so brother goes over there checks the oil first ,nothing on the stick,ends up it was out of oil,how long he drove it like that is unclear, but it still runs !! Them old tractors are tough!

Nobody will believe this story, but seen it happen!

One day a mid 60's Pontiac 389 came in with zero oil pressure, lifters hammering.

Dropped the pan, oil pump was locked and the shaft twisted off. Opened the pump, there was #8 hex nut caught in the gears. How, I can't explain, other than the clogged suction screen lifted enough to let it get by the relief valve.

Cleaned the screen, put a new pump in, started it up, had good pressure, no apparent damage, but I'm sure it didn't do it any good.

Owner said it was driven all the way from his house that morning with the oil light on, about 6 miles!

Customer left his Farmall 450 gas tractor parked near the road at night. Next day, gets on it and starts plowing. Didn't get too far and tractor stalls. He starts looking around and checks the oil. None, plug missing from oil pan.

Then he thinks, well yes, my crescent wrench was in a different spot on the tractor this morning. Don't usually leave it there.

Anyway, he comes to town and gets a plug for pan, fills it up with oil and drives it . About two years later it broke the crankshaft and all the bearings showed signs of oil starvation.

While you have the cover off I would check the rod bearing. I hope it didn't ruin the mains. Too replace the mains you will need a 2 cylinder mechanic and a matching machine shop. Did a similar thing to a 46 flat back A. Had the valves ground in the winter. After putting the head back on I started the tractor and let is set to warm up, ice was blocking the oil pickup and it soon started knocking. Pulled the cover it had one insert rod and one with babbit. Hunted up another insert rod and installed new bearing, the crank was perfect.

as others said, number 8 needs replaced.

no need to drop the whole oil pump. Remove the plate #28 and lower the shaft down so you can get new coupler on it. Be sure to replace gasket #27 with one from JD so you get the proper clearances on the gears.

Thanks for your comments. It was a broken coupling which I was able to find both pieces. Got a new one coming from Yesterdays tractors. Just for my own knowledge are there other old JD parts suppliers that I could also use to find parts?

I've had good luck with Sharps Tractor Parts.

You'd be surprised how many parts DEERE still supplies for these tractors.

The coupling is still available from DEERE for nearly the same price and there'd be no shipping if ordered on a stock order, so it would actually be cheaper if you have a dealer close by to order it and pick it up there!

As a side note, I believe the original couplings were cast iron and broke pretty easily if the pump was stuck by ice or for other reasons, preventing more serious damage.

AFAIK, the new ones sold now are (tougher) machined steel and don't break as easily, just another reason to be sure no water accumulates in the crankcase!
