Hi,
I need some advise if possible
I have owned my little 135 for 2 years now and have recently been having problems with the oil pressure dropping when hot. The engine has been running fine and I have been topping and saw benching since I have had it with a fairly constant oil pressure.
I had an engine oil leak from the bell housing so split the tractor, replaced the clutch, clutch release bearing, clutch fork, split crank seal, gearbox input seals, flywheel starter ring, injector seals, leak off seals, new engine and gearbox oil, new oil filter, couple of fuel pipes and all new gauges. Only to find that it was still leaking when we put it all back together! So front axle off, sump off and new gasket set on the sump, oil leak all fixed.
I have run the tractor for 10-11 hours now and have noticed as soon as the temperature gets up the oil pressure drops. On one gauge it is dropping until it rests on the pin, on a second gauge it drops just into the red.
I have run Mig wire all the way down the gauge tube to the block to make sure it is clear, I have changed the oil to a good 10W40 and done an oil flush by running it for 2 hours and then draining again. Tonight I'm going to see if it does any better with a fixed grade 40 oil and maybe a new oil filter
Can anyone think of anything else I could have done to effect the oil pressure? or could the bottom end bearings or oil pump have worn in a matter of hours?!
Thanks
Karl
