d47u hydraulic leak

I have a d4 7u machine with a leak on the control lever where it goes in the tank.Cat says the seal is discontinued.I was wondering what that seal looks like. Looking fromm the top I cant tell.

Here you go, this is a later improvement. This improvement became effective with SN 6W14542, 7W66ll, 8W518 and 9W5641. Not having your sn it would be hard to say which one you have. But the No 44 Hydraulic controls can be reworked to include the steel washer and snap ring if need be, by deepening the seal counterbore in the case to 21/32” as shown.

look at this thread http://www.acmoc.org/bb/showthread.php?13444-7U-D4-Hydraulic-pump-removal/page2&highlight=44+control+shaft+seal

I think everyone is just stacking 2 seals in there these days instead of the original design.

Hi lj98,

I recently did that seal on my 7U...here's where I got all the info.....http://www.acmoc.org/bb/showthread.php?7627-No-44-Hydraulic-seal-leaking&highlight=no+44+seal

If you just want to see what the seal looks like, search ebay for ...oil seal 11223...plenty of pictures.
