cliff.b Posted June 15, 2022 Author Report Share Posted June 15, 2022 Actually, I have a question about the needle bearing which is probably obvious but I can't get the hub off to see until I get the puller. What limits it's movement inwards along the driveshaft? Is it the taper? Link to comment Share on other sites More sharing options...
johny Posted June 15, 2022 Report Share Posted June 15, 2022 well you want the shaft horribly worn or really good and not somewhere inbetween😬 The needle bearing presses into the housing and has no location on the shaft so its the roller bearing that fixes where the shaft runs relative to the housing...

Ok. Just been reading again and think I understand. So the needle bearing should come away with the hub when it's removed and then you drift it out?

Josef Posted June 15, 2022 Report Share Posted June 15, 2022 Yes the needle bearing and outer ball bearing are both pressed into the hub/trunnion housing. The taper on the outer end of the axle is only to keep the actual hub flange (the bit with the wheel studs) in the correct place. Link to comment Share on other sites More sharing options...

Pete Lewis Posted June 15, 2022 Report Share Posted June 15, 2022 yes the needle roller comes out with the hsg. the main wheel bearing is very tight on the drive shaft but the bearing is a loose fit in the hsg. support the brg hsg in a vice and belt seven bells out on the shaft to remove it there are some adaptors to convert the hub puller to a bearing housing drag but ive always managed with 2 shreaded wheat approach there is a dift it back on dimension in the wsm but its just to get the shaft through enough to fit the hub and start the nut when done up tight it pulls the brg hsg. and back plate into the correct position the shaft is a right tight fit as there is no register on the shaft it sits there with all the cornering loads buy tight fit alone Pete Link to comment Share on other sites More sharing options...

johny Posted June 15, 2022 Report Share Posted June 15, 2022 Id put grease along the whole end of the shaft to help the seal and bearings all slide along. Grease can also be worked into the bearings before installation and then of course once all assembled you'll pump in grease through the nipple until the housing is full...

johny Posted June 15, 2022 Report Share Posted June 15, 2022 no use a bit of grease as youre not relying just on the taper to transmit drive or anything plus it might come apart easier next time.... Link to comment Share on other sites More sharing options...
68vitesse Posted June 15, 2022 Report Share Posted June 15, 2022 Pump grease in before refitting the shaft, I once fitted an inner seal, correct way around, which was pushed out of the trunnion housing by the grease. One from a different supplier solved the problem. Regards Paul. 1 Link to comment Share on other sites More sharing options...

Pete Lewis Posted June 15, 2022 Report Share Posted June 15, 2022 its worth a check that with all the pulling and pushing the hub flange has not been bent or drum wont fit flush etc if bent they can be skimmed in a decent lathe ( studs out ) make sure on re assy that the unused square hole in the trailing shoe is at the bottom ie opposite way up to the leading shoe common they can be upside down pete Link to comment Share on other sites More sharing options...

If it's a tight bearing on the shaft, then does it not stress the race a lot, as the load is taken up by the inner bearing area/part?. Link to comment Share on other sites More sharing options...
johny Posted June 15, 2022 Report Share Posted June 15, 2022 As the bearing is located in the housing theres not much else you can do as theres no way to pull on its inner race as would be kindest. Even the manual shows a special tool that pulls on the housing while pushing the shaft through the bearing although of course this is less stressful to the bearing than whacking. However its all a bit academic as in the end most people would put a new bearing in even if the old was not the problem and this would be pushed in using its inner race. Note though that the thread on the end of driveshaft does need protecting if whacking as its soft and theres another recent thread on here showing a mangled one☹️ Link to comment Share on other sites More sharing options...

johny Posted June 15, 2022 Report Share Posted June 15, 2022 It must have been off recently! Or was the nut not fully torqued up? Link to comment Share on other sites More sharing options...

Well it was part way through a body off refurb when I got it last year, so it could well have been apart then. But if so, why has it failed now? Might be clearer when I get it fully dismantled.
