Rear drum dust excluder

Hi, Has anyone ever had a go at changing the rear drum dust excluders on a canadian carrier, part number CTL 13355B Illustration 2 in the FUC-03?. I inadvertantly grit blastered mine and they need changing, would they be Asbestos?. I think these need to work well in keeping the water/dust & dirt out of your drums to keep your brakes working well.

I think they are leather. Are they the accordian style things that fit around the rod coming out the back of the drum?

I don't have a parts manual available Jordan, but I suspect Kevin is talking about the asbestos strip that runs between the backing plate and the drum.

I would suggest that perhaps the modern fiberglass rope you buy for the doors of wood stoves would work in place of the original.

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.

Hi Kevin,

Did you take any pictures of the operation? I just looked at the pictures I posted in your thread from my repair on the brake cilinder and there is no place to put the packing on the backing plate. Do you put it in the groove of the brake drum then?

Cheers,

hi, yes in the grove on the brake drum. I would say after a few miles recheck the brake drum bearing tightness of the retaining nut as per the manual, as the new seal beds in. I would recommend fitting a seal as per design, leaving it out is not an option even on road driving avoiding mud and water.

nice to meet you at Beltring.
