gearbox salvage and repair

[Lawrie]

recently I seem to have caught up on the PM on my old fords, so got into sorting my workshop.
On the bench was a rough looking gearbox casing (78 -7006).
It had a half baked repair on the rear cluster gear thrust face.
I cleaned it up and dummy assembled a gear set into it.
Measured the end float and worked out what thickness spacer to machine up.
I then found that the cluster gear thrust washer was RS and one of the very hard to get ones.
In my spares I had new 8M-7129 ( readily available), so did a small machining job on the cluster to fit the new thrust washer on .
then, I worked out the dimensions of the spacer and machined one up, I made it so the 8M-7128 washer would fit in and locate on the spacer.
I machined some oil grooves into the spacer to allow more oil to get rear cluster bearing area.(over kill I think)
I also made a dowel to stop my spacer from turning.
All in all ,it turned out better hat I expected.
Now I have a real good spare with an 022A series gearset.
