Tm140 oil leak I can't trace

[tomildinio]

Hello
As title says, tm 140 has a considerable oil leak under the cab. Has painted the underside of cab and transmission and fuel tank. Problem is I cant find it. Have Tried steering and brakes and that while in yard but can't replicate it. Would it be something from transmission in a higher range that only happens on the road?

Thanks
To.

Have you lifted the rubber mat and then taken the panel out of the floor of the cab yet?

Check the steering again. Very common for the steering resonator (6 inch long cylinder) to spring a leak and spray underside of the floor. Access through the floor, but you will see the leak/spray from underneath.

I lifted the floor, which I had forgotten all about since last time . So thanks for that.

Thanks for the tip about the resonator. Was wondering what that was! I'll know for next time!

It was a pressure switch that gave up and was spraying oil. Found it seeping out of the wiring.

Handy fix in the end.

Thanks for the help lads.
