Mark69 Posted June 21, 2021 Report Share Posted June 21, 2021 Looking for recommendations for clutch release bearing , had the box out again due to excessive noise. Found the new rhp bearing contained particles of metal swarf . Quote Link to post Share on other sites
Drewmotty Posted June 21, 2021 Report Share Posted June 21, 2021 (edited) There are a few new old stock RHP bearings about one of which I’ve recently fitted to my TR4. When the new bearing was unpacked it felt a bit notchy. I put this down to the old grease settling and going hard in storage. A few minutes with a heat gun had the grease re distributed and the bearing spinning smoothly. It’s only done 300 miles so far but time will tell.

RogerH Posted June 22, 2021 Report Share Posted June 22, 2021 (edited) Hi Mark, was the noise due to the bearing and not the GB itself? I see that the Moss bearing GRB211 is apprx £20. I'm sure I paid twice this from them about five years ago. and my RHP is working well. Revington sell this https://www.revingtontr.com/search.asp?for=clutch release bearing&cartype=tr6cp and more like the right money.

Kevo_6 Posted June 22, 2021 Report Share Posted June 22, 2021 Hi Mark, I went for the Revingtons H/D release bearing with the phosphorus bronze carrier, very happy with it. If I recall correctly the bearing was marked up as Toyo. Quote Link to post Share on other sites

I’ve ordered a new one, but I’ve also cleaned out the old new one thoroughly with petrol and an airline runs whisper quite. Contemplating repacking with grease.

My mistake cleaned the original bearing also, I think that’s were the contamination came from. These RHP bearings aren’t 100% sealed , so cleaning out and repacking shouldn’t be a problem.

Hi Andrew, mine was really notchy but very noisy, now that I’ve cleaned it I’m sure it will be ok to use once regreased. Quote Link to post Share on other sites
Z320 Posted June 22, 2021 Report Share Posted June 22, 2021 (edited) This bearings indeed are not sealed, but how should dust come in? I used the old one that came with the car for further 12 years without any problem. It's not in use anymore because of a Sachs concentric unit - but well stored. Just an idea: could it be something else is your problem? In which situations "something" was noisy, and how was it noicy, please? Edited June 22, 2021 by Z320 Quote Link to post Share on other sites
Andy Moltu Posted June 22, 2021 Report Share Posted June 22, 2021 Manners sell a Koyo bearing as the uprated version. Being slightly heavier it will eventually eat into the clutch cover but the driven plate will wear out first. The quality of the supplied RHP “originals” has been iffy for years and personally wouldn’t bother. I know some re-grease them prior to fitting, but if you fell that needs doing the logical extension is that other aspects of quality may be similarly deficient.

Mark69 Posted June 26, 2021 Author Report Share Posted June 26, 2021 (edited) Thankfully not the gearbox, put the box back in last night complete with a new release bearing . Tested this morning box is now whisper quite. Happy days. Edited June 26, 2021 by Mark69 Quote Link to post Share on other sites
