Thanks...It should take the worry out of those fast hairpin bends. and im told it will help reduce the torque steer aswell.

What's the final spec on this going to be Andy?

Hi..the engine spec will stay the same, but im changing the wide ratio box out for a standard ratio gearset...Im removing the 3.1 diff and going back to the 3.44...With the cross pin diff..Im runing 12 inch wheels so top speed will be around 100mph at 6000 revs...but the 0-60 time should come down quite a bit...Also the engine power will become more useable on the twisty roads. I was pretty much in 2nd and 3rd the whole time with the old set up...It was fun when the cam was "on" but 2nd to 3rd was a big jump in ratios, so not easy to get the right gear every time...So this new set up should be a lot more fun...if a little noisy on the "A" road cruise..

Hello folks...Tonight ive been building up my new cross pin diff with the 3.44 crown wheel and output shafts from an old diff that was in my Mg Metro..

Old Diff..




All stripped down..



62 divided by 18 = 3.44..



Stripping the cross pin diff, First I removed the short pin by shoving a small screwdriver through the access hole in the other short pin...I had a huge blonde moment with this bit and had to phone John at Guessworks, he was very nice and explained how to remove the short pin...he never laughed at me either...nice bloak..



Once its out you can remove the planet gear it holds in and then push out the long pin.



Once the long pin is out its easy to remove the last short pin which is part of the center section. thats it all stripped..

[AndyMiniMad.]

Rebuilding it is pretty much a reversal of taking it apart, Although you simply plonk in the old output shafts...using the new fibre washers of course..I used an old coffee jar to hold it all.








All done!!



Does any one know how tight it should be? I cant turn the output shafts by hand. but they do move a tiny bit untill the slack gets taken up..is this correct?

[danny1]

might be tight because of the new fibre washers that are in the diff, once its been used and done a few miles it should get better

Not much been happening with the 1312 build this week...But in other news...I bought a clubman...yep! Im officially nuts..the wife isnt speaking to me..Haggis is in bits. im trying to build a 1312 at the back of the garage and ive gone and bought another project..its going to be a busy winter...Pics will be along shortly.

[afoggo]

you have two engines so at least you have another car to put the 1312 in turbo'd clubman and 1380 haggis

[AndyMiniMad.]

The clubman has one of my other engines in it at the moment...I built the 1275 MG metro engine about a18 months ago with the intention of keeping it as a spare, but it somehow found its way into this clubman and has sat in the garage ever since. Any way its coming home now. The guy I bought the car off just never had the time to get it back on the road and ive been pestering him to sell it to me for about a year. so thats it then A very busy time ahead.

[AndyMiniMad.]

So the white clubman has been named "Tatties". He is a bloak just like "Haggis"...Just need a yellow mini now and ill have the full "Burns" supper....lol..

You like riding in a bloke? Will be good to see the new beast!

Thats a bit harsh!! The engine is a girl...but the car is a boy...Its confused about its sexuallity...

Does anyone remember that Cooper S cylinder head?

Well its back from the machine shop, they took 20 thou off the face and it came up pretty good...



Except for this...



So its a door stop!!

In other news...my cross pin diff has been giving me a bit of a hard time..built it up 5 times with new and old fiber washers and it still locks up every time I tighten the crown wheel bolts....

So I spoke to john at Guessworks who informs me that sometimes the new pinion gears can be a bugger to lock onto the old output shafts...something to do with the machining...any way the answer is to fit the old pinion gears onto the new diff pins and see if that cures the problem..

Anyone else had this problem..

[AndyMiniMad.]

Thats me spat out my dummy and chucked the cross pin diff in a box...Its winging its way back to Guessworks as I type this...Fecking thing.. I spoke to martin at MRA this morning and got some good advice, but it still wont turn when the crown wheel bolts are done up, even just finger tight. So bugger it Ive sent it back to get done by the Guru..He will probobly bung it together in five mins and think im a pillock!

Im off to play with the buggy and them off to the pub for the afternoon!! BEER!! the answer to, and cause of all lifes problems...lol..

[AndyMiniMad.]

Thats blown a few cowebs out...Mooocho fun with the buggy!!



Click on the picture to play the vid..Sorry the quallity is rubbish..
