HWH Compartment

My HWH compartment is pretty oily and dirty inside, caked on road grime. I would also like to check the fluid and check each connection for tight. Does anybody have any handy hints on cleaning this area and keeping it clean afterward. Brake Kleen, contact cleaner, Simple Green? A quick look tells me I need to be Plastic Man to get in there and fiddle around with stuff.

The electronics box is also a little beat up looking. Is there anything in there that may require a little attention?

I checked the manual and I didn't find anything specific.

While we're on the subject of keeping things clean, has anybody come up with a solution to a filthy battery compartment?

I just used WD-40 and paper towels. I don't like using water or harsh chemicals around electronics.

Terry, we have a 2005 FDQS. It has the same HWH compartment. I use simple green. If you have oil film it means that something is leaking.

When I have had this problem (twice). It was the hex plugs on the top of the manifold were loose. Also check the o'rings on the loose plugs to make sure they are not cracked.

The 'HWH' compartment is just one of those areas that is going to be a mess. The hydraulic vent on reservoir is going to vaporize some of the fluid when the cylinders are retracting and create a mess. Only when I have to work in that area do I clean it up. Wolfe's advice not to use cleaners is a good one! WD 40 and water hose is what I use. Think about the greasy mess around the driveline joints and just ignore it! I have bushes to prune and weeds to pull!

I was having an oil leak also and it would drip on the ground. I finally found the leak at the rear check valve cap. I removed the cap nut with difficulty and replaced the split o-ring. The top manifold has 4 check valves which are hard to see so I had to work by feel mostly.

Thanks all,

I think I'll clean it up and check all the hoses and O-rings, top off the fluid and just keep it from getting too bad going forward.

Hey Beagle,

I'm in So Cal, There ain't nuthin growin in my yard. Plenty of time for waxing the driveway and dusting the rain gutters
