John Deere B - no oil pressure at pipe to gauge

[andy r]

I have a late model John Deere B that I wanted to get running again. Needs a new battery and probably starter work, but the engine does turn over well by turning the flywheel (had taken the cover off). Filled crankcase with oil. Took the little pipe off at the top of the crankcase that goes to the oil pressure gauge. I cannot get oil to come out of the fitting. Can almost continously turn the engine over by hand with the spark plugs out and no oil it coming out of that fitting. The coupler is on the oil pump drive shaft and it is turning. I have not changed the filter. I don't think water got in the crankcase and froze something, but that could be a possibility. Ideas??? Thanks.

If the oil pump is turning I would check for a plug around the screen to the pump or a broken line to a bearing. Maybe you need to turn it faster. Ron MN

Probably not turning fast enough to create pressure.

Probably not turning fast enough to create pressure.

We are not talking about pressure here, just simply flow.

I've seen the filter/screen cause problems after sitting 10 years or more

Get the starter working & spin it for a while.

Right, I just wanted to see some oil flowing.

Generally on my 2 cylinders you get oil flow just turning it over slowly.

A new filter, new oil, a good crankcase cleaning, and at operating rpm I now have good oil pressure.
