Series 3 Enough teeth left to chew with?

I've been topping the oil up in the gearbox and transfer box of the '78 Santana I bought before Christmas, but I decided to change it all today.

Having drained it, I ran a magnet through the old stuff that had been in the gearbox.


She's lost a few teeth hasn't she? Still works perfectly in all gears though (although there is a tendency to sneak out of 1st when nobody's looking).

Should I be worried about this?

Err in a word. YES

I'll have to google that and do a bit of research into how I can go about that. Is the syncro hub thingy likely to be the culprit of the "slipping out of 1st" issue?

Honestly though, it runs really well in all gears. I treat the gbox like a baby, unlike the previous owner obviously. In fairness, he did tell me about that issue, and also noteworthy is that it only happens when not moving or engine breaking on hills. I just hold it in gently with a fingertip which works easily.

it is,though dog teeth on gear will be worn too, the inner hub outer teeth break away from either side of the 3 slots

Thanks James. I appreciate the heads-up. I'm reading stumpies page http://www.stumpie.com/tech/gearbox/

I'll have to educate myself rápido
