I did, but thought it would be out of my reach. Thanks. -
Where did you get this?

Not visible to my eye, but the camera picked it up. Macro lens Anyway, I've dressed that up as well, and reassembled the thing. Including the selector rod, but not detents, yet. I've done enough for today, turned my back on the mess and walked away. I think I've a decent overdrive, bar the input gear, and that will have to do. Such a shame no one is making new parts for them, but no demand, I suppose. Why do they fail ? Weak design or lack of lubricant? The overdrive is above the transfer box filler so must rely on drip lubrication. What's the problem with overfilling the transfer box? It's got a breather so it won't blow the seals. -

Damn. No, no I didn't see that. I'll strip it down again..... -

And, so a bodge. The macro lens showed a crack and, as the last thing I want is bits of metal rumbling around in the overdrive I ground back to the good metal. -

And I've not got a good one of those, or so it would appear. -

The third one going in, as the transfer box gear is available, should it wear. Plus the lubricant is better for this gear set. -

Next, the output shaft. The first one has tooth cavitation against the layshaft. The second has syncro damage. The third has surface corrosion on the output gear. -

First, the main shaft. I've a better one now so that's going in. Less wear on the input gear bearing surface. -

As I've now got a larger selection of parts I'm re-examining the bits I rebuilt the overdrive with the first time. -

Yep. Modern cars are very good. In general. Nicely boring.

Unfortunately. I've been thinking. How could these overdrives be improved? I mean modified to be better, not a new design or anything! Are the layshaft teeth wearing because the layshaft is too close to the mainshaft? It's possible to mill a new casing, or part casing to move the layshaft. So that's feasible. You could even cut the casing and insert a spacer plate to move the layshaft part further away by 10 mm. What layshaft or gearset could be made work with the input and output gears? Even if the output gear was ground off the shaft and a new one splined on. Again, not easy, but feasible, with wire spark erosion equipment. Ditto, I suppose, for the input gear. Damn it, I need to stop thinking. -

Yet another overdrive. I'll strip this Monday morning, see what I've got. It does turn. And very little play.... -

@Dan John That, sure, is a credit to you. I really like the tray back, such a practical configuration. -

Anyway, I'm off to get another overdrive tomorrow. If this is junk then I'll put in the best layshaft I've got and call it done. -

I beg to differ. I suspect you've more hands on experience than I do. I spend far too much time polishing a chair for a living ...... -

It's true. Sure: I can design and fabricate a bracket, or figure out if something will break, probably. But when it comes to helical gears, I couldn't probably even draw one anymore. Two years of tech drawing at secondary school does NOT an engineer make. -

Every now and then I think about making one of these from new. Then I remember I'm broke and have no engineering skill.... -

I was quoted £600 for one laygear.
