Rear drum dust excluder

Thats a blo_dy good suggestion. Yes Kevin, it is asbestos.

for what its worth on the T16 I did replace the seal. It is a square section gland material that I was able to source from a bearing and pump specialist. It is so tight though that its hard to turn the drum now. I guess it will wear in though.

Hi All,

One thing comes to my mind regarding this seal. Do we really need it with the careful use we make of our machines? I for one never go in water or mud.
This week I have removed one brake drum assembly because of a failed brake cilinder and have not seen a seal in the backing plate. There was no dirt or rust in the drum only a lot of brake dust on all parts. Pitty that the absence of the seal does not make the brake dust disappear.

The failed brake cilinder was a very nicely made reproduction but had one flaw. The pull rod was made of two pieces that had a threaded connection (6mm) and a small tig weld. Both broke off cleanly.

i used grease impregnated felt on mine which should work well enough but i haven't run it yet so i couldn't say for sure that it's ok.

It appears from your photo that the wedges are too soft. The rollers have pushed into them . This would make the load on your pull rod much bigger, as the rollers would be trying to climb out of the trench rather than climb a steady ramp.
I think the pull rod might be a weakness in the design and have seen a couple of broken ones. The pull rod I mean is not shown in your pictures.

Rick, your grease might creep to your linings.

i was not going to use any at all... thoughts being the water would run out the drum...but now i am second guessing myself, i dont intend to have it fording up a river...but the situation may arise where i would have too. hmm some thinking to be done now.

Hi Lynn, You have sharp eyes! The marks on the wedges are there but very slight, hardly indented. The home made rollers were more damaged. They had flat spots and probably did not roll but slide. I have replaced them with two rollers from a cilindrical roller bearing. Now these will probably prove so hard that the wedges will suffer more. However I had no other option at this moment as I have to drive my oldest daughter to her school ball next tuesday. Next time round I will make new parts and have them hardened so they will last.
