hydraulic fan oil and filter

[maureyroad]

Why should the hydraulic fan oil be changed every six months as
directed by the owner's manual? Thanks

I think that is overkill. I bet caution is because the tank reservoir
is where the expansion takes place and the cold oil airspace leaves
room for condensation. when you mix water with the hydrolic oil you get
a foam. the foam air can pack airpressure in the lines and screw with
the pump and rams. (the steering gets spongy) the fan pump and oil also
runs the steering on the pt's.--- In

You are right, it runs the power steering
and fan using 10w – 30 motor oil. 20 quarts. I wonder if there is a
way to extend the change interval. The instructions say to run the engine
at 2100 rpm and if the red light on the rear switch panel comes on then change
the oil and filter. I don’t know how one man can run the engine at
2100 rpm and check the light on the rear switch panel at the same time.
Seems like the light should be on the dash somewhere.

Not shure but I think the light signals that the filter is clogged
enough to cause a filter bypass path to be used??? I think high
filter pressure opens a valve (and glows a light). the open valve
lets oil bypass the compramised filter to continue a path of which is
now unfiltered hydrolic oil???? many oil filters have a bypass
spring in the bottom to prevent pump damage. if the pump doesnt pass
fluid it burns up cause it spinns constant with or without fan or
steering use.

Dan: I have run my oil in the power steering for more than 6 years
without a problem. Oil still looks clear and clean.

Yes, mine is so clear that I wonder if it
is 10w-30 motor oil. But still my owners manual says in one place to
change it every six months and in another place to change it every oil change,
which would be twelve months. Does your manual also mention changing it?

Like Ron's mine has been going four years since the change without adding any oil. All looks well, and yes my manual says to change oil and filters every 6 months or 25,000 whichever comes first. I am now about 5,000 miles away from 25K miles on the change. I will decide what to do at that point. I just cannot see changing those filters every 6 months. That would mean I change them before and after the winter. I have not driven the coach this winter but I start it once a month.

Haven't had time to check the manual. It probably says the same as
yours, but several other scheduled items really don't need that much
attention either.

Ron, I drew a sample from the canister and
sent it in for testing. The fluid may have been clear on top but the
fluid I drew from the bottom of the canister was brown. You know, it
would be nice if someone with some fleet management software could enter all
our coaches in a data base and help manage the maintenance and record keeping
for us. I should have the lab results back by mid week and can give you
the results if you are interested.

Dan: Have you had the coach out on the road recently. If oil is
brown on the bottom, then it sounds like it has been setting still and
some solids have settled. Please do inform me of the analysis.

I use a software to keep all my records. It is called Rolling Stock.
It was designed by a friend of mine and several fleets use it. Not
sure what it cost right now. I was a Beta Tester on it several years
back. If you are interested in it, I'll send you a URL to look at it.
It has a Reminders page to let you know when the next services are due.
