Oil accumulators on tractors

[digger2]

JJ,
You may be right about cost,i dont know.I can see now that its not just a matter of slappin a tank on the tractor,plumbing it up to my oil system,
and let it rip.But,this whole idea of mine started with the fact that it takes about 3 full seconds(maybe more in the winter)to build oil press. on my tractor.It really bothers me.It only does it from a dead cold start,the rest of the day,it doesnt do it no matter how long it sits that day between start ups,
its fine......the pressure builds up right away and the idiot light goes off instantly.
Maybe its some kind of oil "drain back" thing.I dont know.
I do know,its not the oil weight,or filter as i've already tried different weight oils and different filters.Same thing.The tractor works great,it just bothers me.........................Digger2

Where is your oil pressure signal coming from, at the oil filter, lower part of the engine, or from the top part of the engine?

Has anyone ever heard of a Kubota damaged by low startup oil pressure?

Ever???

While it may not 'feel right', Kubota's design engineers must have thought about that possibility and didn't see a need to deal with it. Seems to me that adding complexity just adds more potential points of failure - say if you snag a line in brush, or overlook tightening a secondary filter cannister.

Maybe talking to someone who owns a 30 year old Kubota (with the number of hours on it that you expect to put on yours) would be reassuring.

I had a Moroso accumulator on my race car and took it off. The problem was when the engine was cold,and the oil pressure high,it would push more oil into the accumulator thus lowering the oil level in the pan. When the engine got warm and the oil pressure was lower less oil would be in the accumulator making the oil level in the pan to high. It might not make much difference on a tractor but on a race car when you are measuring time to .0001 of a second, the crank splashing in oil makes a difference.Mine was plumed into the oil galley between the oil pump and the filter so the oil went through the filter. Also for the accumulator,electric selenoid valve, hoses, and pressure switches I have about $700 invested.

Thanks Hooked,
Yeah,i understand about the crank running in the oil thing.I used to run a windage tray in my old '65 mustang i had built up for the street(those where the days).
Anyway,i'm starting to reconsider this whole thing.I guess as already said,the engineers at Kubota are'nt stupid.............Digger2
