morris 1100 transplant.
Riley
I've got the chance to get my hands on a morris 1100. I thought it would
make a nice transplant to my '68.
Is it a straight drop in, with regards to the gear change? did the M1100
have a remote change?
If all this is successful, my other concern is that of final drive. What
would the final drive be in a M1100?
What sort of top speed could I expect with 10 inch wheels? If the final
drive was too low, could I put the final drive from an 850 into the 1100? Is
there any strength problems in using an 850 finaldrive with an 1100
motor?Any other info I may need please feel free to dispay...
mini regards.

You mini probably has 3.44:1 final drive ratio, in the UK the 1100 had 4.1:1
I've used 1100 final drive gears on a mini rally car, they are
interchangeable. 4.1 is too low for road use, like being stuck in third
gear, or maybe like a 5 speed close ratio box without fifth. Perks up the
acceleration though.
When you have the diff out, check the diff pin and planet gears, they are
probably knackered and it is cheaper and easier to change them before they
break and come out through the casing.
Sorry I don't know if the 1100 gear linkage is the same as a mini or
different.

My mate's Austin 1300 had rod change, the Morris 1300 we got an engine out had
a remote change that was not compatible with the mini one. Take the gearchange
from the morris 1100, in case it is different. The changes are the same
length, but had a different flange to bolt to the gearbox.

Problably higher or the same. My mate's Austin 1300 had a 3.65:1 final drive.
The 850 has a high final drive ratio as well...

The gears are interchangable and you don't have take either engine off the
gearbox. Don't forget you need to swap both the pinion and the crown wheel!

850, 3,76:1
1000, 3,44:1
1100, 4,13:1(!) (at least when fitted to Morris 1100)
1300, 3,65:1, the same in a 1275GT (usually)
But this was the case in Europe, don't know if Aus. where different.........
Amazingly; the pinions for the 3,76 and the 3,65 is listed with the same
part#'s.
Hope this is some help,

bothered to change it for the mk2's.
The wheels were 5,60 or 5,50X12", later 155R12".
A few of the earliest 1275GT's are rumoured to have had 4,13:1 also, but
I've never come across one.

The front engine mounts are different as well (2 on the 1100 - 1 on a mini).
If you want to use the 1100 gearbox, and don't want to dismantle the engine
to change the front mounting plate the offending brackets (at least the one
under the generator from memory) needs to be removed. This is commonly done
by cutting it of with an oxy cutter - messy though - much better to change
to mounting plate, might as well replace the timing chain and tensioners at
the same time while its all in bits. The mini mounting hardware bolts on to
the 1100 gearbox OK.
Even though the gearbox casing and diff housing are machined as a pair I
have also seen instances where a different diff housing with the appropriate
gear selector mechanism has been fitted (1100s (1275) into an 850 mini using
the 1100 gearbox and final drive and using the 850 diff housing to retain
the standard gear lever) This was many years ago - the car had terrific
acceleration but not much in the way of top speed (or brakes).

I have successfully transplanted a manual Morris 1300 engine, and had to do
nothing to the morris engine mount plate. It does not foul the mini body in
any way. You just bolt the mini radiator mounting block to the end of the
gearbox and thats it.

You can use the morris gearleaver if you do not want to try and find a
suitable diff cover. Not all diff covers will fit. I personally have tried
this and it wouldn't fit. If you have a selection you may find one that does
fit.
