Our 1955 TEF20 had been suffering from less than effective braking, and coupled with some obvious staining we concluded it was down to knackered axle seals letting oil and the like in to the drums. The Fergie has a lip type seal fitted in the end of the axle housing to stop the rear end oil from sloshing in to the drums. Unfortunately for us this is what the sealing area on the half shaft looks like Attachment DeletedThe dark ring is where the seal runs, and the wear there is very pronounced. Changing the shaft for another one is a right pain as the bearing retaining collars need to be shrunk on and other such work so we'd like to know if anyone can suggest any other solutions |

That looks like a job for a Speedy-Sleeve. These are very thin-walled tube that you gently warm and slide over the shaft, they then cool and shrink down providing a nice smooth surface, barely any higher than the original, that the seal can run on.

Thanks Huffo, that's what the owner's club suggested too. They do a 2"/50.8mm one for about £30 and for that price its worth a go. We may need to heat it and lubricate the shaft a bit to fit the sleeve all the way down but as you say it should do the job nicely. |

Another way is to see if you can source the seal size in a different material - flouroelastomer or leather seals are much more tolerant to localised ridging in the journal, as both can bridge the gap more effectively, although you have to ensure with both that the ridge has no stand-up on either side (when viewed from the side with a magnifying glass or camera close-up). If you have a stand-up, then you need to dress the ridge with a whetstone before trying a new seal.
Do you have any option to position the seal in a slightly different position to the present fitment? This is quite permissible on older vehicles, and was encouraged by Landrover on many rebuild-jobs for transmissions and axles.
Finally, don't disregard the need to find-out what is pressurizing the oil-void within the casing; improving gearbox / axle venting can help considerably in most cases.
