eddeere Posted April 16, 2015 Share Posted April 16, 2015 Decided to check the front brakes and drums. Being not sure on reassembly thought I would check the end play. I could not feel any so I thought would check with a dial indicator. Could not find any movement on dial no mater where I pried or pushed. What is the correct way to reinstall these bearings ? Thanks for any Help. Quote Link to comment https://www.bigmacktrucks.com/topic/39715-b-61-front-wheel-bearings/ Share on other sites More sharing options...
Freightrain Posted April 16, 2015 Share Posted April 16, 2015 I always just did it like a car, snug and spin the hub. Find the spot where the lock bolt goes in and its good. Haven't had an issue. I have the off road repair manual, and likely has the "How to" but never looked. Quote Larry 1959 B61 Liv'n Large......................

wingman Posted April 17, 2015 Share Posted April 17, 2015 Never checked my "Bs" front hubs. I guess I should. Are they wet hubs or grease? Quote Link to comment https://www.bigmacktrucks.com/topic/39715-b-61-front-wheel-bearings/#findComment-286913 Share on other sites More sharing options...
eddeere Posted April 17, 2015 Author Share Posted April 17, 2015 They are grease filled. I finally found the procedure to adjust and repack the bearings in my tec. & service manual under Wheels. Who would have thought ? End play .002 - .008 makes sense. Fill the hub cavity with grease to level of bearing cups and fill the hub cap ( dust cap ) COMPLETELY with grease. Any thoughts on all this grease ? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/39715-b-61-front-wheel-bearings/#findComment-286981 Share on other sites More sharing options...
Gmerrill0516 Posted April 17, 2015 Share Posted April 17, 2015 Never filled things to that level but it won't hurt anything if you do. I just changed the bearings on the front of the 49 LS85 and packed them like my Dad showed me...gobs of grease in the palm of my hand and dap the end of the bearing in till it hits my palm then repeat x 1000...it forces the grease up to the top of the rollers from teh bottom and fills the roller assembly completely. I installed and put some extra all around the area where the bearing sits. I didn't fill it but was not stingey either. It's how I've done car and truck hubs without problems forever... I think the spec on end play is ok too as when they get warm everything will grow and get tighter...too tight is broken. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/39715-b-61-front-wheel-bearings/#findComment-286984 Share on other sites More sharing options...
Freightrain Posted April 17, 2015 Share Posted April 17, 2015 I suppose the grease will loosen up and flow around once warmed, but why? I do mine like above. Enough to pack the bearings, then a bit more mushed around as I install it. Granted I don't run heavy or fast so it hasn't been an issue. I have the bigger axle, wonder if it changes anything on the specs? Quote Larry 1959 B61 Liv'n Large......................

Vladislav Posted April 17, 2015 Share Posted April 17, 2015 My old Mack book (1945) tells "turn the nut up to the end than loose back for 3 notches"It comes about 1/8 of a full rev.I was also searching for the correct way to pack the bearings and was told from the axle factory specialist that with modern grease you need just to pack bearings well and it's enough for 100000 km. Everything else you put in a cavit will just stay there.

Timmyb Posted April 18, 2015 Share Posted April 18, 2015 I use a needle on a grease gun. Bit faster and bit less messy. And I pack a bit of grease in between the bearings as well as a bit of moreys. I tighten them up just enought to remove and free play, and that if I push the tyre from 12 o'clock to 3 o'clock it should do at least one full revolution. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/39715-b-61-front-wheel-bearings/#findComment-287017 Share on other sites More sharing options...
eddeere Posted April 18, 2015 Author Share Posted April 18, 2015 I think what Vladislav said makes sense. My manual is dated July 1, 1961. That's what I get for reading the directions.

gearhead204 Posted April 18, 2015 Share Posted April 18, 2015 better too loose than too tight! i thghten them as tight as i can then roll the hub back and forth then retighten the nut keep doing this till you dont gain movement on the nut, this will have all componets fully seated then loosen nut till loose then bring up till snug (finger tight } then install lock and jam nut. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/39715-b-61-front-wheel-bearings/#findComment-287114 Share on other sites More sharing options...

Vladislav Posted April 25, 2015 Share Posted April 25, 2015 No, the book was for Mack NR 6x4.I'm pretty shure it's a stock front axle used in a LF or BX Mack.
