So I replaced the differential pinion oil seal. Again. It was leaking after only two years.
It was me who fitted the wrong one last time. I really should learn to check parts thoroughly before I fit them.
First drain the oil and check what comes out. There wasn't much magnetic stuff (on the end of the screwdriver) but several large lumps of non-magnetic stuff that turned out to be road grit! Now how did that get there?
With the van on the floor, limited space and my knackered hands, it was going to take more strength than I had available to get the pinion nut off. I fitted it with some heavy grade loctite before.
Cue a special tool to hold the flange (jammed against the chassis), a 3/4 drive socket and a trolley jack to turn it.
That's serious unscrewing power there.
The sleeve of the flange had a deep wear groove which needed sorting. For the first time ever I used the equivalent of a Speedi-sleeve. Filled the wear groove with JB Weld and slipped the sleeve on over the wet epoxy.
As I said it's a first for me and I'm really pleased with the results, compared with getting the component remachined.
New oil seal fitted, and tapped flush with the housing.
The exact correct seal doesn't seem to be available, so I bought one with correct housing and shaft dimensions from a bearing supplier. At last, one that fits!
Reassembled. Refilled with oil. Test drove. Dry as a chip. Job done.
