Ransomes mg6 oil problem

[vhgmcbuddy]

Hi I have just got my ransomes crawler running and have noticed the oil level in the engine is rising.
I have been running the engine with the air supply hose between the carb and the air filter removed as it is poor condition. I am wondering if it is fuel getting into the sump any advice would me most welcome

If your tractor has not run for some time it may be that the crank shaft chamber has collected a quantity of oil which now you are running the engine is being drawn out by the scavenger pump and fed back into the oil tank. This should stop when the chamber is empty. Take a sample of oil out of the tank and see if it smells of petrol to check if it is fuel related. Is it just the hose to the air filter that is in poor condition if so Neil Jarrett carries a stock of these.

Hi thanks I will drain some oil of and see if it smells of fuel

Drain off some oil and it smell of petrol
Tried running the engine but the oil level started to rise
Starting to wonder if fuel is leaking at the fuel pump into the sump
Any one got any ideas

I would say that is definately your problem.

That sounds the likely answer maybe the diaphragm has split

[vhgmcbuddy]

I will order a new diaphragm for the fuel pump
As that looks like the problem
Then change the oil once I am sure the pump is not leaking into the sump

sounds like a good plan Alec

Have now changed the oil after fixing the fuel pump and all seems well
But I may do a second oil change as I found that there was no felt washers at the end of the oil filter.
Neil does not have this spare
Has any one got a fix ? Could I fit a rubber one ?

Sometimes the felt sticks inside the filter housing may be worth checking with a torch.
I made a new one a while ago using carpet felt I used two layers of felt which I soaked with water and put in the freezer and then cut the hole whilst frozen .
