What a Beautiful Mini, I cut my 14 year old teeth on Minis early 80s. At just 18 i had an Genuine 1275GT and life was great. My mate has been working on an R1 front Mounted Mini for over 3 years BUT he has parts from Japan, SUBBED/LIKED as i cannot even @ 51 now get enough of the old Classic Mini.
That Quaife unit looks a lovely bit of kit. Would the drive sprocket go again if you refitted it upside down, so that the force on the teeth tried to pull them in the opposite direction - or is it not worth messing around with, now it's off?
Hey buddy yer I agree it looks good inside, I didn’t expect it to look like that as Iv never opened one up. The sprocket is only about £60 so I’d just have another made up for me
Quaife diffs need a little grip from both wheels, if for instance you had one wheel on ice and the other in a dry road the diff would spin and no drive would go to the wheels, it would be a rare occupancy on the race track but if it was momentary it would a transient issue. I tickle of brake would cure it
Hi, thank you for the video. I also have the same diff and mine seems to have locked up for some reason. I tried to open it up for inspection, but I found nothing abnormal. Could you please share the technical info about your diff ? I would be really helpful to me.
Hi there is you send Quaife a email asking for the torque specs for your diff. It should have a part number on it they will send you all you need mate they did for me
The chain dose have a couple of tight spots just because they get worn out very fast in this car that’s why I’m trying to sores or design a drive box system
I seem to remember that he was having problems with his diff and it turned out that the inner cv pots had gall on the inside of the diff. The need a small bit of lube
Torsten diffs rely on the small gears pressing against the end plates to create friction to stop a wheel spinning. Here’s a thought. Is the molybdenum grease too slippery to generate the friction? Perhaps you need to use a different lubricant like an automatic gearbox uses? Just a thought. If I am correct you would be getting wheelspin. P.S. you shouldn’t use moly oils in synchro boxes as it cases the synchro hubs to baulk and have poor engagement. It’s necessary to use what’s called friction modifiers in the oil. Just my three penneth as in my trials car gearbox I use millers off road oil which is a moly added and adhesive oil. It’s difficult to change gear on the move but preserves my home made differential. Diffs get hammered to death in sporting trials.
Quaife told me it’s basically bearing grease like cv joint stuff and this is pretty clean and the viscosity is lovely as that’s the only maintenance Iv ever done topping it up
You're having issues because your car is too light and your motor doesn't make enough torque. You need to set the diff up as tight as humanly possible, even then it probably wont have a tight enough engagement. You shouldn't be using a helical LSD on that car anyway, a clutch type would be much better
Hope you all enjoyed me finding out it’s not the easy part haha

Thanks buddy, much appreciated. I will get some new videos up soon 👍🏻
Glad to see another of my photos on your end slide! :D Really looking forward to seeing the build of your FMITW V2.0 spaceframe!
Yer mate cracking pick buddy 👍🏻
@@skidmores.garage Just happy it's getting seen, will sit on my hard drive just gather just otherwise!
Them bolts were like a ducks arse lol. Great video matt. Hope you get the mini back on the track soon!
And quaife have given me the torque speck at 26-32lbs so they thread locked the bigger out of them
@@skidmores.garage daft as it may sound but if your getting slip. Maybe clutch? Prob have checked this already matt but just a stab in the dark?
Great video Matt hopefully it's nothing to expensive to replace
Thanks mate and I think this is a cheap fix
I’m doing the same with the diff but can you tell me why you had oval bearing carriers great job mate beautiful mini
It was for space constraints mate, I had to thin down the top so I could get the diff up higher that’s all

She doesn’t spin up much at all being sun 200hp with big slicks to be honest.

With the tooth off the sprocket is there a tight spot in the chain??
The chain dose have a couple of tight spots just because they get worn out very fast in this car that’s why I’m trying to sores or design a drive box system
Are you going to clean the diff up and check it dry, than regrease it and assemble it?
Yer mate going to measure up all the washers and make sure they are with in spec and quaife have sent all the info for that and torque specs for me
what wheels do you use?
Force racing 3 piece buddy
@@skidmores.garage awesome 👌
Chain slipping on the worn sprocket?
I don’t think your car off there mate possibly stretch chain slipping on sprocket it’s looking like
@@skidmores.garage That would be good news, easy/cheap fix. Keep up the good work!
@@MarkLD73 hope so
My mates single seater hillclimb car runs a Torsen diff. Just for your info
Busa 1600 on Methanol
That looks like a Torsen diff too
I seem to remember that he was having problems with his diff and it turned out that the inner cv pots had gall on the inside of the diff. The need a small bit of lube
If it was happening in every gear and you felt slipping. Have you considered the clutch?
i run a quaife and it was the chain slipping on the sprocket so a different chain is now on the car and its 100% better

I am inclined to a green mate. I’m in talks with quaife on one of there drive box system at the moment for the spaceframe build
