seal driveflange is smaller?

[Peter - Belgium]

Hello all,

I got these new seals for the drive flange in the gearbox (1974 highroof), but when I look at the numbers the new one is smaller even though in different topics here I saw the same installed as I got being 42x67x17.6

while the ones installed are 45x72x15

the new seal is indeed very tight if I would place the flange in there so does feel wrong? Are there different types of drive flanges?

Also the circlips for this one, any reference to what I should get?

Thanks!
Peter

What's the part number on the seal? (hard to read it in your photo)

Looks to me like you probably have a later transaxle in your Bus. 091301189 is I think what I see (or with an "A") and that seal is 45 x 72 x 15.

Test fit the seal onto the flange, it should be obvious enough which seal is correct.

From Weddle's website

1976 - 1979 091 trans is 45x72x15
1969 - 1975 002 trans is 42x67x17.6

I recently went through this on a 1971 bus with original gearbox. I called Weddle to order. Those seals have been superceded by a wider seal. Then I called Bigbore in Alaska and he told me you first need to mark the side plates before removing them. Then, using a special socket tool you unscrew the side plate. On the bench you can remove and replace the seal. Then simply screw the side plate back in until you reach the same depth and align your match marks.

So, Weddle sells both seals. Your choice. Don’t forget the big oring that goes around the side plate.

PS-Bigbore sent me his spare special socket as a gift. The time I did the job I used a hammer an soft drift to remove the side plates.

It is easy to make a tool to remove the side plates.

The spacing of the holes is pretty critical. I blew it by maybe a 1/32" and used a larger bolt in one hole to compensate.

With a good seal hook to remove the old seal. The proper sized socket and a bit of metric "all thread" to instal the new seal. Those seals can be replaced without unscrewing the diff brearing threaded collars. it can be a pain sure. But in my opinion you are compramising alot more doing it the other way. But that's just one mans opinion.

Yeah, so I just replaced my flange seals, and there's absolutely no need to unthread the diff adjusting rings to replaces those seals...unless you are replacing the rubber o-ring seal on the adjusting rings, and in that case yes you'd mark them, replace and thread back in to the mark.

Otherwise use a good seal tool to remove the flange seals and press the new one's in. Pretty sure I picked up those axle flange seals for my 002 three rib from Rockauto.

Reuse your circlips, be sure they seat in the groove all the way.
