Hello all. i own a 1995 hijet and for some odd reason, i can't find any info anywhere with regards to the rear diff pinion seal. mine leaks. anyone help please?
I think there is a flange, held by one nut. Undo the nut, and use a gear puller to pull the flange off. This will expose the seal. Use a seal puller to pull it out. Now for the hard part, identify the seal. then buy a new one and install it.
And when you have the flange out check teh outside of it, where it goes through the seal, to see if it has a groove in it. sometimes after lots of miles they and the seal both wear and the leak develops. I’d pull it first to see. But if the guys who listed parts numbers can get numbers for it, you might want to order one.
I’ve only ever needed to replace the flange once, and that was on an old F1 Ford. But that seal is down in the constant dust, and if it starts to weep a bit of oil, I’d expect that it will grab the dust/grit, and start to wear. I know that the front seal on the torsion dampener Of many engines, frequently develops the wear ring, and won’t seal even with a new seal installed. For the dampeners they sell a chromed sleeve which slides over the snout and gives you a good clean surface again. On my venerable Toyota Hilux, with the 20R engine, it developed an oil leak about once every 80-kmiles, and I had to install the two of the sleeves on it.
Speedy Sleeves can be found in many different sizes and can be used in most any application where a seal has worn a groove. Just be very careful and pay close attention to the instructions when installing them as they are a bit touchy to install. I have used them many times in the past. Fred
