tim hunt Posted August 16, 2021 Report Share Posted August 16, 2021 I fitted proper new (and expensive!) Timken bearings 10 years ago, together with an anti-pad knock off kit from TRE and I have not touched the hubs since. By judicious shimming I was able to achieve undetectable end float with zero binding and this condition is unchanged after 55K miles. I note that the 4A owners handbook recommends re-packing these bearings every 24K miles for a car in 'normal' use, as mine is. What is the received wisdom - am I on borrowed time or should I work on the basis of 'It it ain't broke don't fix it'? Tim Quote Link to post Share on other sites
Hamish Posted August 16, 2021 Report Share Posted August 16, 2021 You could ask TRE ? but after 55k think I’d be tempted to have a look and give them some fresh grease H Quote Link to post Share on other sites

Drewmotty Posted August 16, 2021 Report Share Posted August 16, 2021 I’d inspect and repack at that mileage. Quote Link to post Share on other sites
tim hunt Posted August 16, 2021 Author Report Share Posted August 16, 2021 Thanks Hamish and Andrew, I'll err on the side of caution and give them a check/repack. Tim Quote Link to post Share on other sites
dingle Posted August 16, 2021 Report Share Posted August 16, 2021 I would also check that the end float is at least .003". The manuals gives the spec. as .003-.005", but to me, .005" seems excessive. Some end float is necessary to allow for expansion when hot. Berry Quote Link to post Share on other sites

Andy Moltu Posted August 18, 2021 Report Share Posted August 18, 2021 Are the Timken bearings currently available? TRE used to sell them but no mention on their web site these days. Quote Link to post Share on other sites

Rod1883 Posted August 20, 2021 Report Share Posted August 20, 2021 Could I ask what might be a silly question. When "repacking" - exactly how much grease is packed? e.g. For the Front, does the middle chamber need to be be filled/partially filled, or is it just working grease into the bearings themselves?

Drewmotty Posted August 20, 2021 Report Share Posted August 20, 2021 I fully pack the bearing races and just smear a bit around the hub cavity to prevent rusting. Quote Link to post Share on other sites
Hamish Posted August 20, 2021 Report Share Posted August 20, 2021 (edited) as andrew says its really about getting as much grease into the bearings themselves both the inner and outer race. in the old days with motorcycle chains you used to warm a pan of grease so its more fluid, put the chain in and let it cool so it sets again and remove the congealed mess and wipe off the excess not tried it with a bearing yet but it would ensure it is filled.

Rod1883 Posted August 20, 2021 Report Share Posted August 20, 2021 ..I remember doing that with bicycle chains Hamish. I recall there was a branded tin of grease for the purpose I think. Thanks for the comments. It's strange isn't it, all those things we've done before, perhaps with our Fathers advice in our youth, but now either can't recall the detail, or start to overthink it or wonder if we have been doing it right.....

Hamish Posted August 20, 2021 Report Share Posted August 20, 2021 you can still get something similar it seems https://www.ebay.co.uk/itm/124153487479?mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338785333&toolid=10029&_trkparms=ispr%3D1&amdata=enc%3A17Ry1f2rnQ8SG6hSOPeeTgQ45&customid=s%3AGS%3Bgc%3AEAIaIQobChMIiPLqt6i_8gIVuWDmCh3E0gPpEAQYASABEgKbOvD_BwE Quote Link to post Share on other sites
Z320 Posted August 20, 2021 Report Share Posted August 20, 2021 What about fitting grease nipples there? Ups.......a new project? I have to get this out of my mind again..... Supido, supido, stupido (my matra for today) Quote Link to post Share on other sites

Sprays on as a runny liquid and dries as a thin waxy film. Good for the bike and works well on leaf-springs too because it penetrates between the leaves. Quote Link to post Share on other sites
