Good question Bob! I doubt they have done it and the cars were running
anyway.
Thanks,

Has anyone bothered to check whether the factory ever balanced the drums or
even worried about it? It’s not that I don’t care, it’s just I’d like to
know if anyone has heard of that happening at the factory. Bob, 61BT7.

With all this noise about balancing brake drums I thought I had better
take a look at the ones on my BN2.
I'm in the process if machining them back to balance now.
Bit of a task on my 12" lathe but it's happening.

Hendrix welded more material to my drums as needed and it seems to

might affect the integrity of the drum by making it thinner,
effecting the heat distribution and strength. Just some rambling

Mike – I would think that would be the likely explanation for
having sections of the drum rim machined off.

Al, list,
The drums for my BN2 has sections of the raised rim machined
off. Does this mean my drums were balanced in the past?

Bob: If you are wondering about brake drum balancing methods, you
may be interested in the two methods used on my Healeys.
One shop trimmed off the fins as needed to balance the drums, one
needing more trimming than the other – but they both came out
well.
A different shop welded rod material onto my current BJ-8’s drums
to balance them. I think these drums were more out of balance than
on prior cars. They were careful to call me ahead of the operation
to ask how much clearance I had between the wheel and drum, and I
was able to take them a wheel and hub so they could see how it all
fit together. The results are just fine, also.

Harold,
How did you balance the drums - add or remove material? Care to
provide any details?

Another consideration for balancing the rear tires is the
brake drums. I have the original BMC brake drums and was
surprised at how out of balance they were. I static balanced
the brake drums to go with the separately balanced wheels and
tires. No vibrations, shimmies or skuttle shakes so far.

Here in Brisbane there’s at least one place (near me) that
does on-car balancing. The wheels on my 100 don’t have a
central hole, so can’t be balanced on a regular machine. That
said, the last set of Khumo Ecowing ES31s I bought are fine
with no balancing!

I made up my own adaptor using a used hub and knock-off
(spinner). I had a machinist mount the hub on the lathe and
ensure that it was true on the inside edges (where the
bearings fit) and had him put a slight chamfer on the edges
to provide better registration for the standard cones on a
modern balancer. Then we machined the centre out of the
spinner so that when the wheel is mounted on the hub and the
spinner is tightened, the outer cone on the balancer fits
through it and registers on the hub. That part is a little
tricky as if you machine the hole too big, the spinner will
end up in two pieces – measure carefully! Hub and spinner
was $25 at a swap meet and machining was $50. I believe this
adaptor will work on any post-war wire wheels except the
Jags, which had different hubs. Worked a treat on my TC
wheels. Healey is running vibration-free- so leaving it
alone for now.
I too liked on-wheel balancing and in my simple thinking it
balanced the drum or disk at the same time – as long as you
remembered to mark the position of the wheels when you took
them off and did not rotate them (to a different position on
the car)! That is likely one reason they are not used
anymore, because if your drums were out of balance and you
added weights to the wheel that balanced them out, then every
time you removed the wheel, you’d loose the balance, unless
it went back in exactly the same position. Anyhow it’s a
moot point as I have not seen an on-wheel balancer for
decades. I imagine that disks run very true anyhow, but
when I balanced the drums on the TC they were significantly
off. I hear balancing Healey drums brings good results, but
never felt the need as my BT7 has always run pretty smooth.
If anyone in Ontario (Canada) wants drums balanced, Garland
and Sons in Scarborough did great work for me.

It looks like the kit is designed to follow the Dunlop/MWS
recommendations for balancing. See attached. It should be a
good piece of kit.
