Peter Douglas Winn Posted August 30, 2021 Report Share Posted August 30, 2021 Is there anywhere a list of gearbox noises? i.e. a whiring only in top gear with O/D could mean ..... Loud noise when under load could mean ..... another noise only in certain gears could mean the layshaft bearings etc. Put the foor in the clutch and the noise has gone etc. The logic being, if the cog or whatever is not being used or rotating it can't be the cause of the noise or vica versa. I am not an G/B expert. I hear noises and I then have a worrying drive, thinking the worst. The then next drive and I don't notice it. The drive thereafter Oh God the G/B is falling apart. All very nerv racking. Quote Link to post Share on other sites
Xiberras Posted August 31, 2021 Report Share Posted August 31, 2021 Bonjour Moi j'ai un bruit (ronronnement léger) en 4ème OVD pourtant j'ai entièrement refait boîte, OVD et même le pont arrière tous les roulements ont été changés... J'ai peur que quelques chose m'ai échappé dans l'ovd... Bien cordialement Julien Quote Link to post Share on other sites
DRD Posted August 31, 2021 Report Share Posted August 31, 2021 I only thing I'm aware of is that a loud whining in 2nd or 3rd is probably the layshaft bearings. Quote Link to post Share on other sites
Xiberras Posted September 1, 2021 Report Share Posted September 1, 2021 J'ai peur que cela vienne des 3 planétaires et de la couronne dentée du cône Quote Link to post Share on other sites
Peter Douglas Winn Posted September 1, 2021 Author Report Share Posted September 1, 2021 Ok another one. I believe a whine when stationary an going from neutral to 1st gear is the thrust beaing going dry. Quote Link to post Share on other sites
Peter Douglas Winn Posted September 1, 2021 Author Report Share Posted September 1, 2021 Xiberras This is the type of problem that made me ask is there a list. If not, then we should make one. There is a tremendous amount of knowlegde in the club. In fact this question could be extended to other clubs who have simular drive trains. Quote Link to post Share on other sites
Peter Douglas Winn Posted September 1, 2021 Author Report Share Posted September 1, 2021 Can I correct my statement a bit. When activating the pedal and no load then it is normally it is the clutch bearing. Quote Link to post Share on other sites
Xiberras Posted October 9, 2021 Report Share Posted October 9, 2021 Bonjour, Voici la vidéo où l'on peut entendre le bruit de transmission qui se manifeste surtout en 4ème avec et sans OVD sur ma TR6 Pi de 1969. Le pont a été refait entièrement ainsi que la boîte et l'ovd (sauf les roulements des planétaires). Si quelqu'un a le même phénomène n'hésitez pas... Bonne journée Julien Quote Link to post Share on other sites

Bonne journée Julien Hi Folks, here is a translation of Julien's post Hello, Here is the video where we can hear the transmission noise which manifests itself especially in 4th gear with and without OVD on my 1969 TR6 Pi. The bridge has been completely redone as well as the gearbox and the ovd (except the bearings planets). If someone has the same phenomenon do not hesitate ... Good day Julien Roger Quote Link to post Share on other sites
Peter Douglas Winn Posted October 9, 2021 Author Report Share Posted October 9, 2021 That's a new one for me. The coming and going seems to be connected with no load or light load on the transmission. I could not tell if it was in O/D or not. Quote Link to post Share on other sites
John L Posted October 9, 2021 Report Share Posted October 9, 2021 I would say its the diff making the noise. John Quote Link to post Share on other sites

Bonne journée Julien Hello Julien, the noise is clearly a dying differential. I would fix it soon. Teeth break out of the ring gear. That makes a big bang. Not funny. Many greetings Ralf Quote Link to post Share on other sites

Mk2 Chopper Posted October 10, 2021 Report Share Posted October 10, 2021 Can I add my drive train noise here: A kind of droning sound that starts to be heard above 20/25mph, that is quieter/louder/quieter/louder and so on. Can be heard in or out of gear above the 20/25mph. Thanks Gareth Quote Link to post Share on other sites
Mike C Posted October 10, 2021 Report Share Posted October 10, 2021 Have you checked the oil in the diff for both level and metallic particles? It's an easy job to start with. Quote Link to post Share on other sites
Mk2 Chopper Posted October 10, 2021 Report Share Posted October 10, 2021 I've topped up the diff a few times over the years, noise seems to be present regardless. Wondered if a wheel bearing would make that kind of sound (very hard to describe a sound). Gareth Quote Link to post Share on other sites

Peter Douglas Winn Posted October 12, 2021 Author Report Share Posted October 12, 2021 I think we are going at it, the wrong way round. I think the different parts should be listed i.e. Mainshaft Bearing + the noise it can make and when. e.g In all gears and O/D a high frequence screaching or Low frequence Rumbling or or whatever. Perhaps we could build up a data bank on TR noises. Quote Link to post Share on other sites
