<html><body><div style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10pt; color: #000000"><div>Hi Bob,</div><div>Is the collar really preventing the stubaxle from being pulled out? I think that the small bearing housing (the one bolted onto the diff case with 4 screws) is doing that by keeping the outer bearing ring in place? Then , if the bearing can slide on the half shaft, the half shaft and flange can move outwards. I suppose the normal position of the bearing is against that collar. I'm talking about an TR4a IRS : maybe all IRS diff's are not the same : on a TR4A that collar is pressed upon the half shaft not machined and the bearing is on the diff side of the collar.</div><div>Marcel</div><div><br></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>Van: </b>"Robert Lang" <robertlangtr6@yahoo.com><br><b>Aan: </b>"fot" <fot@autox.team.net>, "van mulders marcel" <van.mulders.marcel@telenet.be><br><b>Verzonden: </b>Dinsdag 14 april 2020 14:02:59<br><b>Onderwerp: </b>Re: [Fot] Fwd: TR6 inner shaft bearing<br></div><div><br></div><div data-marker="__QUOTED_TEXT__"><div class="ydp7b2d24fdyahoo-style-wrap" style="font-family:'helvetica neue' , 'helvetica' , 'arial' , sans-serif;font-size:13px">
<div dir="ltr">Hi,</div><div dir="ltr"><br></div><div dir="ltr">It's funny how some things seem to happen coincidentally - I had a customer car in the shop this week with a leaky stub axle. I had a re-conditioned stub axle on the shelf and bolted it in. The seal was clearly not riding on the axle seal surface. I took a test spin and "leak city". Pulled the stub and re-positioned the bearing away from the collar on the axle by about 1/4" to 3/8" (around 6 or 8 mm) and bolted it back up. Leak-free!</div><div dir="ltr"><br></div><div dir="ltr">The bearing moved fairly easily on the shaft.</div><div dir="ltr"><br></div><div dir="ltr">The flange, on the other hand - I have had them on a press and used 30 tons of force and the stub and flange did not separate. Note that when you use a press, do not use a universal collar to support the flange or you will bend the flange.</div><div dir="ltr"><br></div><div dir="ltr">Regarding whether there's a"fix" for the bearing walking on the shaft, the answer is: there's a collar machined on the differential side of the stub axle that keeps the axle stub from pulling out and if forces try to push the stub towards the differential eventually the bearing bottoms on the output flange. But that stub position can move around a bit.<br></div><div dir="ltr"><br></div><div dir="ltr">Good luck!</div><div dir="ltr"><br></div><div dir="ltr">Regards,</div><div dir="ltr">Bob Lang<br></div><br>
