Inner Oil Seal Problem (1 Viewer)

[LC_Hamma]

Both my inner oil seals have become dislodged & therefore the diff fluid dissolved all the grease in my birfs I thought about somehow adding a large washer (pictured) to retain the oil seals. Do you think I should drill & tap the housing & use countersunk screws to retain the washer? Could the birf rub against the washer even when I'm using a screw to hold out the birf at the drive flange? I'm running the Long 30's with his supplied oil seals. Thanks!

Get the new Marlin Crawler seal. Not sure what is provided with the Longs, but these look great.

Thanks for the reply. I totally forgot about those new seals from Marlin. I'd rather give those a try before I take a chance & possibly have my birfs grind on that washer

Why is this happening Chuck?


What is going on in the axle housing, causing the seal to be popped out of the seat?

What seals are these?

I have installed a few of these 30 spline Long set-ups, and have not seen any special seals with them....

Maybe the shafts aren't centered in the housing via shims on the knuckles? That's all I can think of... No, I don't have the tool to center it up, I just guessed at the shims thinkin it can't be *that far off. The seals are the one's Bobby supplies with his Supersets.

Marlin's Heavy duty inner axle oil seals:

Thanks David, but I am aware of Marlin’s new inner axle seal, and have 16 here on hand.


I was referring to the seals that Chuck was talking about that apparently come with the 30 spline Longfields now.....

The longs are machined before they are heat treated to save wear on the machines. When they are heat treated it can introduce a little bit of run out (measured as much as .026" in one case). Marlin says his new seals hold up to it. Having inspected a pair and examined them next to a set of stockers I believe him. I think they are worth the money. Especially considering the time and money he's got invested into bringing them to market.
