Hello all,

apologies for the delay in reply, Family illness and bereavement from August on last year.

Anyway, lots of various issues, chief among which is vanishing oil pressure. starts fine, no knocks or smoke, gets to heat (say 20 mins) and pressure just falls away. New oil and filter done.

Next move is a new oil pump. Managed to get an oil pump body off ebay and new stator/rotor internals.. just need time to fit it!!

Any thoughts, tips, etc.?


Cheers
CAM

P.S, also looking for another one if anyone knows of a good, Road registered one?

It is quite common to have low oil pressure on a TED20, I have heard of several running quite happily with next to no pressure at all!
When you changed your oil what grade did you use, they like a straight SAE 30 or 40 in them, don't use a multigrade as the detergent will clean out accumulated build up from over the years and cause a lot of problems.
Is it low pressure on tick over but will pick up when you rev the engine or does it just drop away regardless, also what sort of oil pressure are you getting?

I'm not an expert but I think that the oil pump drive shaft from the cam shaft is inside the main oil-way to the engine bearings etc and is sealed by a flat bronze bush under the gear wheel. The camshaft rotation tends to push the gear wheel down but make sure that the distributor is pushed right into its housing so that it holds the drive shaft gear wheel against the bush

Cheers Iain,

It's had a new distributor it seems, so you may be onto something there!! Will give that a look!!

Much appreciated!

Something else we have found very common recently is the ball bearing in the Oil Pressure Relief Valve being in poor condition.
On most of the tractors we have looked at the bearing is pitted or generally in bad condition, which will allow oil to escape and pressure drop.
Those which we have replaced saw less of a drop in oil pressure once warm, one to look out for!

There is someone selling them on ebay. They also sell refurbished oil pumps with a new rotor installed.

When refitting the oil pump to engine, some believe a gasket is not required (pressure side)... personally I think its a much safer bet to install the gasket.
