Hi Pat,

Paypal payment sent.

Pinion seal is weeping and has slight play so will need doing soon but still usable (when it's not snowing).

Thanks,

Paul

It may be an idea for me to construct a fixture and special tools for overhauling these units.
I am not sure how we could work it but it would be good to have these available to the community.

I LOVE THIS PLACE

Sounds like a cracking idea Pat,

the main problem aside from the castle socket is actually holding the FD while taking apart,

I was going to make a jig, should be pretty easy,can't see what other special tools needed?

from total dread to now being do able thanks to the collective

I think you'll be on a winner with this idea Pat....
The holding frame would be a good one to start with

Some sort of jig that can be bolted to a work bench would be good.
I thought of something similar myself but don't have the facilities (or skill) you have.
Maybe a three prongs the drive could be slid onto, one through the main axle hole, the other two through the swingarm pivot points?

These nuts are plenty tight, you need a good solid fixture to hold it down.
Let me think about it.

would a windy shift it?

Doesn't Steptoe use one of these...

Unless, like Pat, you've done this job, it's very difficult to imagine just how tight the bloody nut is and how much torque you need to undo it. We are talking swinging off a scaffold pole tight and hence the jig to hold it needs to be equally mighty.

What worked for me was a jig made from 2" box section. An upright welded to this went through the axle hole. A large alloy plate bolted to the wheel carrier prevented it's rotation by being bolted to a second upright. The whole lot was clamped in a BIG vice with a 4" wooden post cut to stand from the floor to under the FD swing-arm bearing to counter the torque reaction when swinging off the scaffold pole. I also added a large bolt which screwed up against my home brewed (and rubbish) castle nut socket forcing it hard into the castle nut to prevent the socket popping off when heaved on.

Even with a 10ft pole on the socket driver, nothing shifted until I took a blowlamp to the FD housing.

It's VERY, VERY tight, honest.

We are I presume talking of torque in the region of 200Nm? Steptoe’s impact gun goes up to 400Lb/ft (thats 542Nm), whatever torque you might need to slacken it off, don't you think that gun would do it, or have I got it wrong?

Hold it... that gun costs around £250
