If anyone needs any advise on building a Midlands let me know....I think I'm becoming an expert!

 

The Midlands got an up-grade!

 

Thanks Nathan. I downloaded it, I'll need that soon enough. I should buy one that's already blown and fix it so I'll have one ready when mine finally gives up.

 

I found a service manual on line for this and printed it out I can scan it if needed.

 

Dang. That looks like so much fun, now I wish I had a blown Midlands.

 

Seems I'm the CR guru now

 

Here's a few photos regarding the C clamps and my straight cut gear set.



This is what happens with low oil.



The 3 types of Mini synchro rings. Peugeot uses the one piece non fiber ring




For sure the torx bolts will round off so I weld a nut on. When rebuilding a Midlands it is always wise to buy the 4 C clamp bolts and at lease 1 or 2 bearing plate bolts.



When the C clamp wear the 5th gear inner hub gets worn away



The forks wear away too!



Here's a worn and broken C clamp.



New clamps from Eminiparts.com



I collect the Midlands boxes mainly for spares.



The Peugeot gear set has a C clip instead of a nut



Straight cut set with Gripper LSD. I went for the straight cut synchro set instead of the dog box because my Mini is a daily driver.



When the gears or crown wheel let go the casing is always busted.



My swap from a normal gear set to straight cut. I went for a straight cut crown wheel and pinion too!



This is what happens when you don't change the oil on a regular basis! Sludge in the oil ways....not good.



Peugeot rings.

 

Amazing. Hope all is well Chris.
