Change of gearbox

Post by **psjorge** » Thu Mar 19, 2009 6:29 pm

Hi,

I'm afraid that my question may be absolutly nonsense but I'l make it anyway...

Is it physically possible to couple to an 948 cc engine the gearbox used in conjunction with the old sidevalve 918cc engine?

If so, is that feasable or just a funny way to reck both components?

Thanks,
Pedro

Anything is possible if you engineer it - but this would not in any way be a 'bolt on' operation.

If you want to maintain the "magic Wand" gearstick that goes through the floor further forward ie. no remote linkage, I beleive this can be done with the later box.The best person to talk to is John Evans who advertises in the club mag.

Dear Longdog,

You read my mind! In fact have a January '54 Series II (whitch means previous to the major changes that took place on October that year) that should have a 803cc engine and corresponding gearbox. I write should because it hasn't! Someone has changed it to the later 948cc engine and later type gearbox. Eventualy I'd like to bring the car back to its original engine but have failed to find one until now. The reason because I would like to do this is to keep things as original as possible. As you pointed out, the gearstick is different, a bit more backwards. This means that I have to use a later type gearbox cover and the correct-for-the-year pattern of carpeting does not fit and also have to use the later type handbrake lever because the correct one is too long for such a backwards positioned gearstick and interferes with it!

Due to the fact that I found a 918cc engine and corresponding gearbox I thought that it might be feasable to swap them.

I understand now that it is not so I'll try to contact Jonh Evans as you advise me.

My thanks,
Pedro

"Pauln" has a suitable gearbox and cover for sale - in the Parts for Sale section! Even if you only use the gearlever etc and fit the bits to your 948 box, probably worth the money.
