Hyd Tank lid o-ring

May 31, 2015, 02:41:56 pm

Has anyone replace there o-ring when changing the 3 nelson filters 84220A. I have changed them 2 times and want to change the oil and filters again. I went to Cummins NW no help, checked with Kevin no help. It looks like this system BUT it is not the same. Mine is round and this one is beveled. Any help on this would be great.

Our hydraulic oil tank looks just like the one in your link. So did the ones in our previous two coaches, both Monaco's. The part number I used to order from Ryder Fleet Products was 99955A. Our gasket/O-ring is beveled just like in the pictures. Don't see why it would not work on yours.
There have been some changes and confusion about some of these part numbers in the last few years. I think Fleetguard (Cummins) bought out some of the product lines from Nelson et al or introduced compatible competing products of their own. There are several different part numbers for the hydraulic filters out there at the moment.

FWIW,
