R.E.D Posted January 20, 2022 Share Posted January 20, 2022 My s cam bushings are shot..I plan on doing an rear end complete overhaul pretty soon..I go to the mack dealer for an unrelated part and ask for a quote for all the brake components for the two drive axles.i ask for the metal s cam bushings not the plastic..guy at the counter says he has never heard of metal s cam bushings..and he has been working for mack for 14years...I didn't want to sit there and argue with the guy so I played dumb and got my part and left...but I remember I installed brass or bronze s cam bushings on my Rd before .does anyone have the part number for the bronze bushings?crd92 93 I believe.. thanks Red Quote Link to comment https://www.bigmacktrucks.com/topic/69087-s-cam-bushings/ Share on other sites More sharing options...

Onyx610 Posted January 20, 2022 Share Posted January 20, 2022 I heard that the metal bushings are better for like dump trucks and the plastic are fine for highway trucks. As the dumps are mostly stop and go and lots of brake applications….

mechohaulic Posted January 20, 2022 Share Posted January 20, 2022 77 is NOT an excuse ;;;; it's a REASON ..LOL . i'm on my way to 71. challenge is trying to answer questions on the forums when the brain thinks of the 60's=70's applications , comical when a post says " i have an old truck 20--; that's new to us old timers. to the topic, bronze bushings were used in all applications then. it was a world with out plastic parts. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69087-s-cam-bushings/#findComment-487516 Share on other sites More sharing options...
theakerstwo Posted January 20, 2022 Share Posted January 20, 2022 I started in 1965 so i still think of those trucks and alot of them in the later 50s were made in the 50s. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/69087-s-cam-bushings/#findComment-487518 Share on other sites More sharing options...

Mark T Posted January 20, 2022 Share Posted January 20, 2022 I've seen adds for a different kind of bushing. EtCon ??? or something like that. I've often wondered if they would be better than plastic. I almost think they don't require grease either...... not many of those free magazines come anymore, used to see them in the back pages.

Joey Mack Posted January 20, 2022 Share Posted January 20, 2022 for me, at $500.00 per barrel of grease, I would get pissy when I saw piles of grease on the floor.. couldnt get a few of them to just watch for it to purge before it hits the floor.. anyway,,, grease is GOOD. we know that... jojo 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69087-s-cam-bushings/#findComment-487524 Share on other sites More sharing options...

R.E.D Posted January 20, 2022 Author Share Posted January 20, 2022 I pump untill new grease shows , except scams, because as mechaulic suggested they fill , the brake shoe with grease and could create unwanted problems.

Onyx610 Posted January 20, 2022 Share Posted January 20, 2022 Pumping until the old grease is out and new grease shows was suggested by bendix. If the seals are working correctly it should never go towards the brake shoes. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69087-s-cam-bushings/#findComment-487529 Share on other sites More sharing options...
