Thread: Oil seal, between gearbox & transfer case

Despite my reluctance about pulling the gear box out, it turned out to be the best move I ever made...!

When I came to pull out the clutch linkage from the bell housing, it was to discover that one of the pins through the connecting tube, had broken into three parts. I would have been really p......d off, had I put the box back in to then discover that it would have to come out again..!

Anyway it turned out all oil seals need replacement and the seal on the main shaft, was approaching 5 on the moh scale it was that hard, not surprising really considering that I've never changed it and I've had the vehicle 40 years. But no wonder the oil was flooding past.

And so the plot thickens..! Removing the oil seal on the output shaft, revealed
that the bearing behind, had seized and was spinning within the insert...!

It's to be hoped that loctite will rescue the situation.

The clutch operating shaft is bu ..........red not to mention the bronze spherical bearing. I reckon I might be able to remanufacture the shaft and I was wondering if a high tensile bolt would suffice as a locating dowel through the connection sleeve...?

Any ideas guys..?

Thanks,

A high tensile bolt would work, but the proper pins are available and are probably harder than the HT bolt. A mild steel bolt will not work (for long).

Buying the bits and pieces to repair the clutch linkage is proving to be a costly venture, the hardened pins are $23-00 each and the minimum quantity is 10 Off.{}#%\|]{} ...??

I,m also having trouble coming to terms with the cost of the remaining items.

So I've decided to remanufacture the operating arm, using a HT 5/8" bolt as the shaft, and buying the bearing from an alternate supplier.

Does anyone know where I can get the pins, on a two off basis, nd also the spherical bronze bearing...?

Thanks,

Norm.

It is a long time since I bought mine but try L. R. Series Ltd - specialists in land rover, land rover series and range rover - gearbox, axle, transmission parts, spares and major units

Alternatively any fitter can turn down a piece of high carbon steel such as EN24, or EN26 for you and harden and temper it - I suggest temper it to a blue colour.

I can't remember the diameter of the pin but if it is 1/4", you could buy a parallel punch and use that; it would need to be softened first so that the holes could be drilled and then hardened and tempered.

If you know someone with a lathe and an oxy-set so much the better,
