Gearbox question !

[bmcecosse]

Is a 1275 Spridget gearbox in any way different to a 1098 Minor gearbox ?

[Matt]

It will definately fit and work (ok... if the box works anyway...). I think the ratios are very slightly different, but not particularly. They also have a provision for a reversing light switch!!!

Thanks Matt - I was wondering about the splines on the input shaft - will it take the Minor clutch plate ok ?

I think you will find that some of the gears run needle bearings.

I think you will find that some of the gears run needle bearings.

is that on the input shaft/ and out put.
all these g/boxes have needle rollers on the layshaft.

what you could do is find the part number for the sprite clutch and see if its the same for the minor.

[Matt]

Im pretty sure the box will fit...

[bmcecosse]

Thanks all so far. Did the Spridget box ever get the 4 syncro gears from the Mini ?

[Matt]

no

[les]

Brixton, I cannot answer your question with any certainty, but it is my understanding that the needle bearings fitted are in additional areas to those in the Minor box.

[bmcecosse]

Which is why I asked if the 4 syncro ever reached the Spridget box - because it was around that time that the Mini box gained needle rollers under the main gears.

[Willie]

The spridget 1275 gearboxes had needle roller bearings on the 2nd/3rd
gears instead of the Minors bronze bushes.

[bmcecosse]

Ok - many thanks again.

i have a 1275 midget gearbox in my van and it works just fine, clutch is a bit harder but apart from that it is ok and stronger for the 1275 engines a good combination

[bmcecosse]

Aye - well if I can just find an in-line 1275 engine !! Got 4 Mini 1275s in stock, but no in-line ones up here these days !
