Also how did you try to find the wheel seal number ? Stemco has cross reference charts on-line. Also.. is your DM a '79 ? seal number still Visbal on old seal by picture.

Reseal it, make sure the S cam is straightish. Get the slack adjuster in a vice and wind it around and around while pumping it with grease until all the dry old grease is out I usually pump mine with diesel and then re grease When it's re assembled, the brakes should snap back otofwhenffrom when they are on, fixing a dragging brake on the side of the road os no fun Anyway, I'll leave it in your capable hands Paul I used the the stemco grit guard seal and band for years, never a problem with it. terry 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/86/#findComment-583031 Share on other sites More sharing options...

mowerman Posted Friday at 02:34 PM Author Share Posted Friday at 02:34 PM Yeah, thanks for that. I used to have a spring tool for a car. I don’t know if I still have it. I can’t find it. I’ve got way too much shit around here and I could never find anything. I lost my grease gun when we moved here 20 year ago it’s out there somewhere Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/86/#findComment-583046 Share on other sites More sharing options...

Joey Mack Posted Saturday at 08:44 PM Share Posted Saturday at 08:44 PM Bob... I looked in my Library of Mack books and I dont have info about wheel ends for any '66 Macks. What range of years shared the same wheel end parts ?

mowerman Posted Saturday at 09:42 PM Author Share Posted Saturday at 09:42 PM Well, it probably is one step up from a B model since it’s a 66 and they were still building the B model beginning of the year so it probably got the same rear ends 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/86/#findComment-583098 Share on other sites More sharing options...
Joey Mack Posted Saturday at 09:57 PM Share Posted Saturday at 09:57 PM The shield on the back of the hub resembles those on the B Model. And the inner seal as well.. i am in no way smart about B Models.. i have done a lot to a few of them, but not enough to post correctly. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/86/#findComment-583100 Share on other sites More sharing options...
