Rear drum dust excluder

[kevin powles]

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?

[kevin powles]

hi jordan, no these are for stoping dirt/mud/water getting into the brake drums, check out the illustartion, i will post up a picture this week.

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.

[Lynn Eades]

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.

[Lynn Eades]

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.

Wow,driving your daughter to the school ball in your carrier,major cool,Marc!

I had thoughts of taking my date to the School Ball in my Dad's old carrier, but then I thought about the physics of a Ball Dress and high heels.... I shall leave the rest to your, I am sure, very vivid imaginations....

I once, many years ago took my carrier to the battalions Officeers mess summer ball near Cambridge at a big Stately home with a realy long drive. It was as an interest point after thier meal, some of the other guys took a Ferret Sout car. when they came out to view the "Then and Now " RECCE vehicles. Well they had all had a few "drinkies" during the meal so they were a little happy to say the least. Anyway we ended up giving rides down the 1 mile long drive in both the Carrier and the Ferret. At one point i had my Colonel (drunk as a skunk) standing in the commander position of the carrier leaning forward of the front armour with sword drawn, shouting at the top of his voice "CHARGE" as we rattled down the drive with several of teh "ladies" in the back. They were all wearing very expensive frocks with lots of lace (not the Col !). in the morning both the carrier and the Ferret were full of very pretty lace tatters.
On another note we did a school summer ball last year for a local girl and won "best arrival vehicle".
All good fun !!!!

I am really looking forward to tomorrow evening! My only worry is the wheather forecast.....

Hi, I have today, cleared out the old asbestos dust excluder and put in 7/16" square graphite bearing keep packing, go's in a treat. ready for a run up the beach off a landing craft now.

[Marc van Aalderen]

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,

[kevin powles]

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.
