Hudraulic Fluid Change

Yahoo Message Number: 5392
The "book" says to drain the hydraulic reservoir and replace the fluid (16 quarts). No problem. Except - what is the best way to drain the reservoir? It does not have a drain plug on the bottom.
Do we remove one of the hoses from the bottom?

Thanks in advance for any help.

-Hi J Brown,

Consider either siponing it out with a clear plastic hose or use a $8 drill pump and garden hoses either purchased from any ACE hardware.
Word of caution - don't let any foreign material get in the fluid you replace. There are 3 filters that need replacement.

J & MJ Brown,

I called CC with the exact same question. I was told that the system is a closed system that only required changing the filters every 15,000 miles. This advice was based on the fact that nothing from the outside had contaminated the system. I was told the filters will remove normal contamination, but the oil itself will not break down.

Interesting topic. Not sure where there is a reservoir that holds 16 qts. Can you be more specific on the hydraulic system you are referring to? I assume you are talking about the reservoir in the engine area? Or, are you talking about the reservoir in the LH forward service bay for the slide system? Both take Dexron III, I believe. Or, is it something else?

Jim,

We're referring to the hydraulic reservoir that is located in the engine bay. It has 3 stacked filters. The system runs the radiator fan.

Hope this helps........

Gentleman,

That system also runs the power steering, I changed mine filters and fluid and I noticed that the pulsating I had, in the steering wheel, while turning the wheel at low engine Rpm's went away, so it's important to check this fluid.

Gentleman,

One more note you should not use Dexron (even though the CC manual says you can) in the HWH slide out system. This is because if you ever have a leak the Dexron will make a mess and they say it will soften the grout in the floor tiles and also it will make a real mess and is hard to clean up. HWH makes a special oil for the slide out pump system, and it can be found at camping world.

I guess if your in a jam you could use the Dexron, it will work but if you ever get a leak the above could happen and leaks will happen at some point and time.

Steve,

Thanks for the info. I was wondering what the interval and requirement was for that specific system was. I have just never noticed it in the manuals before. I sure wish Country Coach would take all the scheduled maintenance items and put them on a chart. It sure would make things a whole lot easier than digging through all the manuals.

I am in the process of setting up a maintenance log in the VMSpc system I have. The fluid and filters for the fan motor and steering hydraulic systems will be another one to add.
Based on someone else's comment on the HWH slide fluid, I assume that their has been not problem using Dexron III in the reservoir in the engine bay? Where are the stacked filters you referred to located? I have an ISC330 in my coach and I looked at it briefly this weekend. From what I see, I assume the filters are located inside the reservoir assembly? Is this a do-it-yourself job for someone who is mechanical? Anyone have a part number and source for them?

I would think that the entire system holds 16 quarts because the reservoir looks like it will hold maybe 8 quarts at best. I wonder how important it is to get all the old fluid out of the system? I am always concerned about mixing old unknown fluids with new. There could be a perferred method to purge out the old fluid downstream somehow.

I enjoy the challenges.

Jim,

I have the 350 ISC but I assume they are the same. Looking in the rear engine access the tank is on the right, just inside. It has a vent & dipstick on top. The tank is approx 9" X 20". There is a sticker on top referring to using 10 micron filters and checking fluid level hot. It gives a Nelson part #84220A. I checked around but never found a source for Nelson filters. I get mine from CC---$34 including shipping.

Remove the top after cleaning to avoid contamination & inside you'll find a large wing nut, washer & spring. Remove the wing nut and the filters slide up & off a shaft easily. Replace in reverse order. One of the easiest & cleanest maintenance procedures there is to do.

Hope this helps

Do you have the part no. name, and cost for the filters for the hydraulic system to run the radiator fan. I tried to find these in the past and no one seemed to know what filters they took. Happened to be going to

Camp Country Coach and ended up having them change them out for me. Neglected to get filter name and part no.
Thanks

The filter number is documented in your manual. My coach is a 2003 Intrigue with the Cummins 400 ISL engine. It uses the Nelson 84220A filter available at most Cummins parts locations. I think most Country Coaches use the same filter. Your filter number may even be printed on the top of the filter canister. I happened to buy mine from the Cummins parts store near Lazydays. They were $28.34 for the set of 3.

Since we're the ones who started this discussion about the hydraulic fluid change, let us add a few tidbits of information. Yes - the part number for the filters is Nelson 84220A. However, in some parts of the country, Cummins is not the Nelson distributor. Here in West Virginia, the Nelson filters are sold through Fleet-Pride stores.
The part number in the CC manual (with the exploded view of the reservoir) is apparently a CC number - neither Cummins nor Fleet- Pride recognized that number.

Also - for those of you who are working on a "complete" maintenance schedule - there's a coolant filter located just forward of the engine oil filter. This coolant filter is supposed to be changed at 15,000 miles (or one year). You might figure on changing it at the same time as the engine oil filter - because it's next to impossible to remove and replace with the engine oil filter in place.

And - there are probably more items that require replacement/change at various intervals - the CC books are difficult to decipher sometimes.

Hi J,

My Coach is 30780 so were real close on numbers. I can't go 15,000 miles on the Coolant Filter, 6,000 is just about right. I do all my own maintenance and at 6,000 miles, the DCA level is out of range.
The best bet is to check it with a DCA strip to see were it's at.
You may be in the low range before reaching 15,000. You can also try different fleetguard filters with more or less DCA depending on what you need.

On my hydraulic reservoir, I pumped out the fluid when I changed the filters. Probably wasn't necessary, but it was no big deal. At least the reservoir got fresh fluid.

A note of caution to anyone changing their coolant filters, be sure to TURN THE VALVE back on when your finished...

Tom: Just about the time I think I have these acronyms figgered out, somebody comes up with another one. What the duce are the DCA levels in the cooling system? I have a 350 ISC in a 99 Intrigue and have changed the coolant filter once in 40k. Since it is clear that you do know what your doing, how about a little advice: My engine is prone to overheating on long grades and in hot weather if I don't down shift manually and keep the RPM's up. At least, I have had the red light come on once or twice before I began to watch the gauge closely and keep the "R''s up. I have never had a light for more than a few seconds and have never had to shut down. The most extreme condition last year was in 100' ambient temperature up some steep grades pulling a Honda. I got down to 25 MPH in second gear just to keep the temp light from coming on. Does the aformentioned DCA level and the change of filters have anything to do with the cooling properties of the anti-freeze, or is it just to keep the system clean?(which may be the same, huh?) Also, have you heard of the high-temperature coolants some folks run as replacements for conventional anti-freeze? Thanks,
Larry
