Re: Hydraulic pump Maintance? Reply #26 – December 16, 2016, 04:25:03 pm Ya, I have no problem with 25,000 miles or every 3 years unless here is a problem in the system. These systems are pretty well sealed and stay pretty clean. Again, I am NOT suggesting a complete fluid change unless there is contamination. Just change what is in the reservoir and change the filters. Even the top gasket doesn't need to be changed unless is leaks (you will see oil on the outside of the reservoir. You loose zero oil changing the lid gasket. Quote Selected 1 Likes
Re: Hydraulic pump Maintance? Reply #27 – December 16, 2016, 10:49:19 pm I have an oil "weep" or leak at the seal on the hyd motor shaft for the radiator fan...... how big of a deal is this? Quote Selected

Re: Hydraulic pump Maintance? Reply #31 – December 17, 2016, 08:14:10 am I had some small leaks that had gotten pretty dirty over time on mine. Bernd guys cleaned and pulled the motors and replaced the shaft seals. I also got a complete hydraulic fluid and filter change as part of the work. So far, everything seems to be running good.Rich Quote Selected

It was a very dirty job but the money saved was well worth it to me. Quote Selected
Re: Hydraulic pump Maintance? Reply #33 – December 17, 2016, 01:45:29 pm I swapped to hydraulic fluid for my hydraulic system. Reason being, hydraulic fluid has more additives designed for hydraulic systems (pumps, motors, etc). Shepard says it is acceptable for the steering box. Quote Selected 1 Likes
Re: Hydraulic pump Maintance? Reply #34 – December 17, 2016, 11:24:18 pm By far the best way to drain the tank is to blow the main hydraulic line that goes from the pump to the first fan motor. That'll help you really get ALL the oil out of the system For what it's worth I use Rotella non-synthetic in the hydraulic system while I use T6 in the engine and generator. Hope it's good stuff.

Remember, this is a sealed system and not exposed to outside contamination. Quote Selected

Re: Hydraulic pump Maintance? Reply #37 – December 18, 2016, 12:49:37 pm Hey Chuck, that is how we changed our Hyd oil out last winter on trip. First going down the 285 to Hilton Head from 95 the hose blew and left a nice line down the Hwy. Fixed that one with new hose then a few weeks later the top seals in Steering box blew so again the coach and car and hwy around Gulf was "oiled" so another fix and new oil. I think the regular way to drain it is a better idea but this does do the whole lot.JohnH Quote Selected
