Anyone tried swapping S Cam Bushings withougt removing Cam?

good --i forgot about that--pull the cam carrier off---might have to warm around the screws a bit to make it easy--then you can pull it off and drive the bushing out--put the new bushing and seal in and good to go--- saves some money--and a lot of time
and dot cant check the outer bushing either
although it will have wear--its probabely not that bad
good luck

 

hmmm trying to get my memory working again,sometimes its slow

at the end of the s-cam---at the slack adjuster there will be a lock ring--then a washer or 2--pull those off--then take the pin out of the clevis at slack adjuster,and you can adjust your slack adjuster so it clears the clevis and be pulled off of the s-cam
then probabely another washer on cam then a lock ring

then have to take the 4 bolts out that hold the carrier to the spider--being that they are torks---makes it a bit more difficult--but a bit of heat around the screws might help--then you should be able to pull the tube off---there will be a tiny o-ring on the inside outer shoulder of the tube as well
i sure hope i am not forgetting something and it will screw the job up
iirc the inner bushing will be in the tube as well--cause the tube fits right up into the spider--now as long as the s-cam doesnt slip in or the rollers pop out you should be ok

it is kind of a messed up way to do it--i would definately prefer to do it the regular old way---
maybe do a google and see if you can get a blow up of the assy just to be sure---once the tube is off and out there wont be anything supporting the s-cam other than if is between the rollers--i would sure hate to see it fall in and then you have to take everything apart anyways

HOLD IT___HOLD IT

HOLD IT--i usually work on trucks--so i just had a huge brain fart
on the trailer--you dont have a cam carrier tube do you?---isnt the s-cam inner bushing just in a holder that is welded to the axle???
like most of the s-cam is just out there in the open?
hell yes just split that inner housing apart drive the bushing out--clean as good as you can put the new bushing in and put it all together


sorry ---i feel like a dork--i was thinking of the way trucks s-cams are held in

ok i finally found a pic--so what you have is like the lower pic right?
if so yes --you can just do th inner bushings--easy job--there is no cam tube----see i told you my memeory doesnt work some days

but on this system if your outer bushing is worn --dot can check that cause the s-cam isnt in a tube

sorry for giving you misinformation and wasting an hour of your time

 

sorry bout that--my brain went automatically to truck brake setups---the trailers tend be a little more replacement friendly----
so basically its more or less the same with the lock ring and washers
ok i have to go work on the garage--i have had my DUH moment of the day

 

good thing--glad you had no troubles

 

When the DOT checks it they just look at the top brake shoe and the bottom brake shoe if there is any difference in thickness, they know the inner bushing is worn, They can also back off the brakes and use a screw driver under the lower shoe if it moves that is the wear.
When I worked at a transport company they use to, replace the brakes and rotate the "S" cam 180 degrees the next time they pulled the hub and replaced the "S" cams and bushings. If you have worn inner bushings and adjust the brakes the bottom shoe drags, Fuel costs to much to waist.
