wishthisMackwouldwork Posted January 28 Author Share Posted January 28 2 minutes ago, Joey Mack said: SKF has a line of speedy sleeves. When you can, measure the diameter of the spindle where the seal goes. Use a caliper. The part number of the sleeve contains the measurement.. I used one of these for the seal, but the race for the inner bearing must have been spinning for a while, as it had 1/16- 1/8 of slop. It looks like they dont make them that thick. The one for the seal was paper thin.

Real man labor is in huge shortage here. Hope the JB holds. But at least its painted! Well at least it looks nice. I like the color combo and the stripe Quote Link to comment https://www.bigmacktrucks.com/topic/74995-rear-hub-disaster-in-1986-rm-with-meritor-axle/page/2/#findComment-567994 Share on other sites More sharing options...
Joseph Cummings Posted January 28 Share Posted January 28 When I was doing large industrial drives and gearboxes I bought a lot of stuff from this bearing house. They always went far out of their way to find me stuff. Shipping was fast too https://jrkbearings.com/ Quote Link to comment https://www.bigmacktrucks.com/topic/74995-rear-hub-disaster-in-1986-rm-with-meritor-axle/page/2/#findComment-567996 Share on other sites More sharing options...
Joseph Cummings Posted January 28 Share Posted January 28 $642 Holy Chit. is it made out of gold or something? Pretty soon we are going to have to go back to hardwood bearings lubricated with possum grease Quote Link to comment https://www.bigmacktrucks.com/topic/74995-rear-hub-disaster-in-1986-rm-with-meritor-axle/page/2/#findComment-567997 Share on other sites More sharing options...

Geoff Weeks Posted January 28 Share Posted January 28 I hadn't finished my coffee before I posted, so made a mistake. However, there are many options. The shaft size is 3.75 and the bore as it is now is 6.75, You could have a sleeve made to bring the O/D down to 6" and get a real common 594 bearing. That make the sleeve thick enough to not be a problem. The shaft size has more an effect on the load capacity then the OD of the bearing. It is even possible that someone in the past bored out the hub to make a repair and put that odd ball bearing in there. A good machine shop should be able to fix you with something that is a permanent repair. You need to measure the seal diameter at the spindle, if a common size, the best thing would be to press in a sleeve in the hub to take a common bearing and seal.

Joseph Cummings Posted January 28 Share Posted January 28 Janka Scale Scores: Lignum Vitae =4,500 Hard Maple, Sugar Maple 1,450 Lignum Vitae is 3 times the hardest of Maple bearings and is self-lubricating. Maple bearings are currently impregnated with oil, grease, or wax that can’t match the lubricity or low friction that Lignum Vitae offers. If you are using Maple bearings as a screw, roll or conveying machinery bearing for agriculture try Lignum Vitae wood bearings and enjoy much longer life from the bearing, less downtime and better operation. I think I'm going to plant me a couple of these suckers so I can have bearings after the EMP, zombie apocalypse, collapse of the financial system 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74995-rear-hub-disaster-in-1986-rm-with-meritor-axle/page/2/#findComment-568002 Share on other sites More sharing options...
Geoff Weeks Posted January 28 Share Posted January 28 (edited) Can't tell from pictures, but if the seal bore is or over 7.125" you could have the hub bored to accept a 776/772 combo and your done. https://www.ebay.com/itm/126201388758?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=126201388758&targetid=2299003535955&device=c&mktype=pla&googleloc=9018343&poi=&campaignid=21214315381&mkgroupid=161363866036&rlsatarget=pla-2299003535955&abcId=9407526&merchantid=118875154&gad_source=1&gclid=EAIaIQobChMIvYah3YeZiwMVWDuHAx0yvyDmEAQYASABEgIXs_D_BwE Edited January 28 by Geoff Weeks Quote Link to comment https://www.bigmacktrucks.com/topic/74995-rear-hub-disaster-in-1986-rm-with-meritor-axle/page/2/#findComment-568005 Share on other sites More sharing options...
