Post Re: Fixing an unwound gearbox.
Ok, so I have some spare time, the weather outside is sunny, and my special tools came this morning - so it's game on for this gearbox.

Image

Despite looking at several photo's provided by Viking and others I still can't make out clearly what it is I'm supposed to be screwing to where. The part that I found unscrewed in there had a normal r/h thread, and I have screwed it back on to where I assumed it came from?

Image

Here's a close up...have I got it? :?
The car is in neutral now as I was able to push it out of the garage to see a little better in the daylight so that's an improvement. If I have got it back to where it should be where do I now need to peen it and how many times? It's bloody difficult to see what's what even in daylight.

As no one has had time to answer yet I'll just tag this other question on.

If I'm right in thinking that I've got this thing screwed back where it belongs two things strike me. How do I know when it's back on properly? Or is it just a case of screwing it back on as hard as I can? And secondly, when I come to peen it over what part am I trying to hit?

Am I right in thinking that I need to hit the recessed part of this (and presumably other) segment where the screwdriver point is, thus hitting it up and toward the front of the car?

Not so fast young man

Do this. Your screwdriver angle is wrong.

Don't use a center punch. It may not hold if the metal is soft. Use a screwdriver

I think I need a torch, can't see a darned thing. Thanks Viking, I'm on the right track at least then.

Right peening done, if in fact that's what I have actually done. 'Keep hitting it 'till it's dented all round' would be my explanation of what has just taken place, and the angle shown in vikings photo is impossible to acquire, I even sawed a screwdriver in half to make it shorter but the hammer still hits the bulkhead.

Old-Nail,
looks to me as though you've got it pretty well pinned down.

Been having too much fun welding a bodyshell today, otherwise I might have had a look on the forum earlier.

The main thing is that you've managed to 'persuade' metal of the selector ring into the grooves in the sliding pinion in as many positions as you can identify.
( Not into the spaces _between_ the grooves as once recommended on here... ;) )

ken

( Almost forgot, be careful when putting the lid back on that the selector rod is correctly positioned in the notches in the rods _before_ you start tightening the bolts. )

Ahh...thanks Ken. That's a better photo of what it was I should have been attempting, or at least I can easily see what's been done on there whereas I wasn't so sure before. Regarding replacing the lid, should the selector forks be set into neutral then to make the selector rod engage easier?
