gearbox problem
Turbo Mini Forums

hi again i was just out in my turbo came round a bend and the steering went stiff then as i pulled in to let a car through i went to set of and there is no go now it goes in 1st 2nd 4rth rev but not 3rd but iven in 124 i let the clutch out and there is no movement any ideas

echhhhhhhhhhhhhhhh...........

sounds like..........?

the diff pins gone

yep diff pin/mainshaft. happy days.

ahhh is it easy to fix or is it engine out time

was just talking to pot dan about you. he said it still drove in 1,2,4 thats why i didnt think it was the diff pin! lol!

or maybe i wasnt reading right!

But you can do these with the engine in on metro cant you?

are the mg and turbo diff pins the same

if it is the diff pin replace it with a competition
pin.

you got any ideas of where i can get one

any of the big mini dealers.check the mags.

ive havnt had a decent comp diff yet which has been better than a genuine rover one.

ive used all so called makes and have found that the diametrer of the pin is very slightly thinner than the genuine ones, we are talking microns but it does seem to make a difference. plus the oil slots i dont think work as good as the criss cross set of the gen pin.

this is another reason i think half decent turbo motors realey need 4 pin diffs. as well as sc gears.

always looking for them bigger bunches of bannanas

also dont forget to replace the planets, not just the pin.

right lads got my car on ramps ready to remove the diff just draining oil at the mo can anyone give me some tips on wat to do and wat not or should i just rip the bloody thing off
do you remove the shafts or repair the diff in place
cheers lee

mettyturbos first thread stated that it did not drive but he could engage the gears except 3rd

metty:
my advice to you is remove the btm balljoints
pull the shafts out of the couplings and remove the pot joints

i think it may be possible to remove the diff housing with the engine still in on a metro?

but my advice to you you would be to remove the engine incase you have to go furthure into the problem.

this is the best option

but some may disagree

Hes only just got the engine back in too :(

On that metro i just undid the top ball joints and leaned the hubs, that made them pop out for me to get the pot cup things out.

I was wondering, what gasket do you use for the dif housing? Of just some universal blue?

some of the later metros were glued together with that hideous blue stuff hylomar.

and diff shimming to tolerances were all machined to suit

if you found this before its the above then hylomar

but if not use the gaskets.

good check is, remove the drive shafts as surgested, then grap each output shaft with your hands and then push together and twist in opposite directions if it is nice and smooth then i may sugest it could be somthing a bit more than a smashed diff. as it will go in 3 gears and not in 3rd sugest not a diff as it would be the same for allgears (well in theory any way).

could be a shredded 3 rd gear on either the lay shaft or 3rd on the main shaft.

but i could be wrong but hope you get it sorted.

right got the diff of its tottaly disintagrated but all the gears have gone into my gear box i dont think this is looking good i think engine rebuild number 3 is on the cards

sorry to hear that buddy well opt for a minispares 4 pin diff next time metty

happy rebuilding
