[Healeys] Brake backing plate bolts

[Mark Donaldson]

To all of you who replied to my question - Thank you.

 

Bill, I think you are right on the button with your assumption.  

Half of the Nyloc nuts had little or no locking nylon and were visibly
'chewed', quite likely by a Neanderthal mechanic.  Luckily I had good spares
to replace them.

 

Dusting off the shelves at the back of my memory banks I remembered I had an
old rear axle in my loft.

There were the nuts - in perfect condition - protected by decades of oily
road film and dust - with no washers, as you had all told me.

 

Cheers,

 

Mark

Sounds like someone was using the original nylocks and didn't trust them to
lock a second time. Thus the redundant lock washers.

I recently disassembled a rear end to convert to disc brakes. The backing
plates were held on only with nyloc nuts - no washers.

Learned gentlemen,

 

When I took the backing plates off the rear axle of my '62 BT7 race car the
four bolts each side had Nyloc nuts, with lock washers underneath.

With the lock washer in place the top of the thread did not connect with the
nylon - but it did with the washer removed.

The parts book shows just the bolts and nuts.  It does not show any washers.

As the car was built in Hayward, CA, in the mid-seventies as a track car,
there is much about it which is not standard.

 

My questions are:  

1.	Are the Nyloc nuts correct and, if not, what should be there?
2.	Is it correct to have no washers under the nuts?  I would have
though it correct to have at least a thin flat washer, even though the parts
book appears to show none.
