Pinion seal on two speed rear end

[jsd245]

Anyone ever do one of these on the big trucks? It seems fairly straightforward without a lot of the complications on rear ends with the crush sleeves. It’s seems I can unbolt and pull the yoke, and just replace the seal. Since the bearing races are shimmed it doesn’t seem like the torque on the bolt that secures the yoke isn’t that critical? The service manual doesn’t really have instructions for this style rear end I can find.

I can't speak for the big boys specifically, but if your flange has a groove where the seal rode, it'll leak again with a new seal. I've had good results repairing with a speedi-sleeve made by SKF. You have to pull the flange, measure the diameter of the shaft, then look up to see what size will fit....

Pull the yoke..make sure no pitting or wear groove...install new proper seal carefully.

If yoke has a groove -new speedi-sleeve required.

Install as directed.

 No crush sleeve used in your Eaton 1350...tighten as per shop book torque specs.

Of course oil the seal lip.

So I finally got this done- in case anyone needs it-the Eaton 1350 two speed axle in these 1.5 ton trucks seal and Speedi sleeve parts numbers-

 

seal- SKF 22425

speedi sleeve for the yoke- 99225
