Ditto on blocking heat hose from any coolant passing through it. Heater hose on my '91 JD 4255 has had heater hose cut-off valve closed since 1994. Is radiator, condenser, evaporator & AC filters very clean from dirt/debris????? Next one needs to attach AC gauges to determine if refrigerant...

Many yrs ago I installed an adjustable flow control valve on boom circuit on a M4900 that had a Kubota FEL. Feathering cable controlled FEL spool valve while handling 1000 # rd bales with a 49 HP with sufficient rear counterbalance weight didn't suit this Old Man that had been operating...

Check to be sure fuel tank vent is open/not clogged. Many yrs ago I had a M4900 that lacked power. After I performed most common fuel diagnostics procedures the local Kubota dealer service manager advised me to closely inspect gallies in water separator housing. I found a small screen on fuel...

How many hrs of use since hyd filters were changed?

Check/clean all 4 battery cable connections.

I think I read post # 1 of this thread but my "OLDTIMERS" is rearing it's ugly head therefore I can't remember if I read post #1 of this thread but that wouldn't have affected my reply if I had remembered reading 1st reply!!;)

The title of this thread clearly states ""Anybody having problems with Messicks web site?""

Messicks parts site opened like normal for me on my PC using Chrome. https://www.messicks.com/catalogs/kubota/m7040hd/engine/300001-crank-case-old-s-no-8s0230-note-order-by-ref-no-010-and-fig-no-315001-or-03-ref-no-040-070-080-new-parts

I agree as it sounds as if hyd oil was contaminated with water. I suggest to check trans case vent to be sure it's not clogged. One could test old hyd ooil by placing a small amount in a pan then heating to determine if heated oil emitted a crackling sound.

Normally hyd pump's don't just suddenly bite the dust! I suggest to perform good hyd diagnostic procedures before entertaining idea of replacing the hyd pump. I suggest checking hyd pressure with a gauge. I've also owned a ''11 M7040 since 2012. My guess is debris is in hyd relief valve...

Do you know if shuttle/reverser control is manual or relay controlled? My M7040 is manual via a cable controlled & some other model Kubota's are relay/electronically controlled.

You could utilize a product such as observed in the following link to detect water in fuel...

I'll suggest to check for good fuel flow from tank to inj pump. Is fuel tank vent open? Many yrs ago I had a similar fuel problem on a Kubota M4900 tractor that local dealer service manager advised me to check for blockage in water separator housing. Upon closer inspection I located a tiny...

I suggest to perform good hydraulic diagnostic procedures. My guess is your tractor has a faulty hydraulic relief valve or possibly 3pt hitch is raised too high due to maladjusted 3pt feedback rod. Over my many yrs since 1965 of being associated with repairing tractors I've read/heard of many...

My having owned both synchronized & hyd reverser type Kubota tractors I'll recommend hydraulic shuttle over synchronized shuttle. Hydraulic shuttle uses hyd reverser clutch instead of a dry traction clutch to control tractor fwd/rev motion. The Sync reverser om ,y Kubota M4900 failed @ 1500 hrs...
