J type o/d and spitfire o/d gearbox put back together

[hardhatharry]

I have diverged from my project build thread as this might get complicated

 

Quite a while ago I "won" an ebay auction for an o/d, gearbox and bell housing for a 1500 spitty, they were in 3 parts and described as bought from a previous owner who stated "it failed in 4th when o/d not engaged". Quizzing the guy who I bought it off and found out thats the only info he received when he bought the bits. I have done a bit of visual inspection and there doesnt seem to be anything obviously wrong. My plan is to connect the 3 bits back together and build a j type o/d test bed as seen on a few youtube vids. The three separate parts seem complete and just need screwing together but how? Looks at a few exploded diagrams but they all are of each separate bit not connected together

The first question concerns the location of 2 circlips and spacer washer pictured. Where do they go?

Initially I thought the large one went here

But there already is a circlip on the bearing that sits in that recess.

I have no idea where the spacer washer or the smaller circlip goes by they are of a similar size.

The next question is what goes here in the hole?

Is it the rod from the selector like so?

Third question I assume there is a certain setup in the gearbox you need to select when first setting up the box with the o/d, can someone advise?

Any help gratefully received

Shame!😟. But seriously, My 1984 Haynes GT-6 manual seems to show circlips in both bearings front and rear of the `box. Is that what you have?.

Yes both front and rear bearings have large and small circlips on them

[PeteH]

Do you have the Manual?. I don`t know how well the Diagrams would scan?.

As its this far apart I would carry on and look at the critical mainshaft tip and layshaft needle bearings. You might get it to run smoothly on a test bed but it wouldnt be transmitting any torque so theres nothing like a close visual inspection....

on the circlip front the small one with the plier holes is used behind the rear case and the input shaft  bearings  which seem already fitted 

the  large is a spare that fit around the bearing outer ring to control its position in the case   both yours are fitted ,

so they are spares 

the OD pump cam is held on a woodruf key and a round wire circlip to retain the cam in position  ...it looks in place ok

your right with the remote rod but as i puzzled about this nasty linkage  earlier n,  ive not done a J on  a single rail mix.

I have never stripped the gearbox but this attachment might help.
