Post subject:  Torque for subframe mount bolts

I'd like to know what torque settings should be used for the subframe mount bolts/nuts (if there is any specific settings) for 1978 Clubman

Front subframe :
Tower nuts (for pair of tower bolts)
Front bolt/nuts

Rear Subframe :
Bolts into heelboard
Bolts through floorpan

Also, I need to replace all the bolts so should all these bolts be high tensile?

Thanks.

The Tower Nuts should be nylocs so they should be tight, they cannot be set with a torque wrench.

All other Nuts/ Bolts for the front subframe should be 18-20 ft/lbs.

All rear Subframe to Body bolts and nut / bolt sets are also 18 - 20 ft/lbs.

I've never bothered to torque them, just make sure they are adequately done up.

The original fasteners were Grade 5 tensile (3 straight lines on the bolt heads) and these are fine.

according to who?

the ones on my car are definitely not nylocs, they are standard nuts with a steel locking "tab" that goes underneath.

and the subframe has never been out of the car.

however it is an early mini, the later ones might have changed to nylocs. i couldn't tell you for certain though, as i don't own any wind-up window minis.

According to Leyland.

Yes early cars were fitted with normal nuts and these would have been torqued to 18 - 20 ft lbs. I don't know exactly when they changed to nylocs. The sheet metal thingy they put under these nuts has locktabs for the early cars.

<EDIT> There was also a brief time when Bolts were used in the towers in the Oz assembled Minis

I've had cars with all three varieties, the nylocs are the easiest IMHO

re the 4 rear ones in the floor, I found they tend to come loose on my road car (even with new spring washers), and I got sick of retightening them.
They now have locknuts on em. I guess putting nylocs there would work too.
