Hi

Does anyone know if the 22g1100 slots directly in place of the 22g232 without the need to replace/change anything else, in other words is it a direct replacement? Is it the same 22g1100 as used on the sprite, midget etc? Also, minispares and somerford do the 22g1100, are these pattern parts or as good as new old stock/originals?

If anyone has a new old stock 22g232 or 22g1100 then I'd be very interested in buying it.

Basically the box has been in to be refurbed but he says he can't get a replacement laygear, I've said the 22g1100 is the same and is available but he says it won't fit without changing other bits and it will be poor quality anyway, in other words don't bother. The laygear that's in has some pitting on the first gear end, not really bad, but since the rest has cost a lot it seems a false economy to leave it in as it will be the 'weakest link'. He won't be drawn on how bad he thinks it is, he says it may last 5 minutes or 20000 miles, so.... He also said there is another part "that's a bit chewed where the teflon is coming away but still slots in", does this make any sense to anyone? "Teflon" in a mini?

Gearbox is a 3 synchro 22g68 Cooper 998cc box with a 22g232 laygear.

Any help greatly appreciated. Pretty stressed over this tbh as it's cost double what I thought and still has problems. Just wondering whether to make do with the laygear and "teflon" part as it is and accept it's 50 years old, despite the outlay already.

Many thanks

This will give you an idea of what real bad is or isn't. Might be worthwhile to post your location/country too as people all over the world browse this forum. They may have the parts you need but shipping may not be economical.

This document states 22g232 has been re numbered to 22g1100. Have heard modern lay shafts are a bit naff though.

Teflon was invented in 1938 but I doubt it would be in a mini. Without being more specific I couldn't even guess what he is on about, unless it's something to do with the gearstick.

22g1100 is a direct replacement for 22g232 however reproductions can be of varying quality so it can be very hard to find nos gears.

I've just fitted a Minispares 22G1100 laygear to my Mk1 S gearbox....it has lasted more than 5 miles so far I know of other people who have done the same without issues. One thing we did find was that we had to take a little bit of meat off one of the thrust washers to get the gear to slot in nicely. Oh and they apparently ship without the circlips and spacer that you'll find hold the bearings in the correct place in your original gear.

Maybe he means the molybdenum material on the cone , where the balk ring grips , these had chipped away on my box , causing gear crunching

Thanks for all the replies.

He also said he had to cut down the layshaft to fit. Does that make sense? It's a 3 syncro, seems these layshafts are available without the need to bodge? I know there were two lengths, the 4 syncro being longer. Got a feeling he's just bought a 4 syncro kit and then 'made' it fit. He said he'd bought a 'kit' from minispares and they only appear to have a 4 syncro one. Feel free to tell me I've made a mistake going to him. Anyone know someone oop north who could check it over and do the remedial work, someone I can trust.

Cheers.

BLT , where are you located ?

We are in south warwickshire and do loads of 3 syncro box,s

Hello,this topic is very timely for me,as I am about to rebuild/restore my Mk 1 Cooper S gearbox.Most of the parts to be used are genuine N.O.S BMC or Leyland items.However the options for the laygear at present seem to be the pattern ones in the images attached.Does anyone have experience with the long term reliability of these laygears? Are there any better options readily available?Any employees of well established Mini spare parts suppliers can PM me if they so desire,information will be treated with the strictest confidence! Thank you.

I'd also be very interested in the experiences people have had with these aftermarket/reproduction parts.

I'm after a 22G232 or 22G1100 original nos laygear(in wanted section) for my Cooper box. I know the 22G1100 is available from various places but I assume these are all reproductions. So much has been said about 'Italian' ones etc being made of 'chocolate' but what is this based on? After all they make some good cars so why not gears, in fact why are they made in Italy?

Anyway, I have an Italian(I think) repro one here and it looks really good, but unlike a door handle or some external bit, if it turns out to be rubbish and disintegrates then all sorts of carnage may result. I've read they are inferior steel and the hardening is not good. But is this really true? Therefore I'm not sure whether to use it in case it tears the gearbox apart.

So are the repro's actually any good, Italian or otherwise and where are the best ones sourced, or are they all from the same supplier? Also, does anyone have any direct experience of them, have you got one in your gearbox that's lasted and working fine or disintegrated after a few miles?

Thanks in advance for any advice.

BTW, 251 ENG, I'm in North Yorkshire

I'm using a Minispares 22G1100 laygear on my S box, bought in 2013. So far, no problems and it has taken some abuse. I wonder how many people try to fit A type first synchro hubs to these B type gears (because originals are most of the times thrashed) and then complain the new gears break.
