Paul H Posted February 6, 2020 Report Share Posted February 6, 2020 Hi. Just giving my Vitesse some fresh air , and a clattering noise as if something is loose . Only comes on under load so at 30 mph in 4th all ok , open her up and clattering starts , slow down and the noise stops Only thing that has happened is the clutch was stuck on , one day I will learn to leave it out of gear . To release I put the car in reverse ( I drive into my garage ) and started the engine and it freed almost straight away . Could I have done any damage ?

Iain T Posted February 6, 2020 Report Share Posted February 6, 2020 Hi Paul, do you have original gearbox? I have a type 9 and they do clatter at low revs, it's the nature of the beast. Just stir the box to get revs up and all's OK. Iain Link to comment Share on other sites More sharing options...
Nigel Clark Posted February 6, 2020 Report Share Posted February 6, 2020 Where does the noise seem to come from? It's possible the jolt freeing the clutch could have damaged the clutch friction plate, causing spring(s) to loosen and rattle. However, that would likely go quiet under load.

Nigel Hi Nigel clatter coming from gearbox though can never be sure , dip the clutch and clatter stops . Was wondering if I’d done in a Uj on the prop with the jolt Paul Link to comment Share on other sites More sharing options...
Iain T Posted February 6, 2020 Report Share Posted February 6, 2020 Hmmm, if it's a new noise then something may have gone array. I don't have any experience with Triumph 'boxes so I have to bow to the greater wisdom in the Forum. Iain Link to comment Share on other sites More sharing options...
Iain T Posted February 6, 2020 Report Share Posted February 6, 2020 Paul, I would have thought if the UJ was damaged the noise would occur in various gears when under load and slowing down plus probably driveline vibration. How long ago was the gearbox reconditioned? Did you replace the clutch release bearing? Iain Link to comment Share on other sites More sharing options...
dave.vitesse Posted February 6, 2020 Report Share Posted February 6, 2020 Paul, It may be something to do with the clutch release mechanism. Have a look around the release fork. Dave Link to comment Share on other sites More sharing options...

Iain T Posted February 6, 2020 Report Share Posted February 6, 2020 I would make sure the arm moves smoothly back and forth. From memory it pivots on a ball mounted on the side of the bell housing and the arm is retained by a spring clip in a depression in the arm. Is there any driveline vibration?

Pete Lewis Posted February 6, 2020 Report Share Posted February 6, 2020 i would also look at crank endfloat and fan fixing bolts'bushes i would not expect a lightly stuck disc to wreck the damper springs as it didnt take much to free it off if you have the tunneloff feel the throw out lever when the noise appears , is doing any odd vibrations ??

Iain T Posted February 6, 2020 Report Share Posted February 6, 2020 Paul, silly question but has this noise occurred on first drive after seized clutch? Pete, surely end float would be an issue every time the clutch was operated and in whatever gear? Iain Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 6, 2020 Report Share Posted February 6, 2020 do make sure this is gearbox ??? related , not something daft like a loose front number plate ...they make a good racket Pete Link to comment Share on other sites More sharing options...

Pete Hi Pete . Fan fixing bolts , do I just check if they are tight ? Endfloat check . This is inserting smallish wrecker bar to see what movement there is ? Checking the throw out lever with the cover off makes good sense Was my clutch freeing off method wrong ? Paul Link to comment Share on other sites More sharing options...

Stuck clutch yesterday , freed off and left to idle for 10 mins . Today was first run since freeing the clutch Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 6, 2020 Report Share Posted February 6, 2020 fan sits on rubber bushes give it a good wiggle lots of ancilliaries can make a racket even a dry fan belt nothing wrong with freeing off method. if it was seriously stuck things can get gorilla mode and still survive pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 6, 2020 Report Share Posted February 6, 2020 thinking out the box, has a pushrod jumped out of its rocker ?? yes Ian endfloat making flywheel foul rear plate all /any time is this engine knock, what happens in 1st 2nd 3rd 4th ?? frequency of the clatter engine related or prop rev related ?? pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted February 6, 2020 Report Share Posted February 6, 2020 7 minutes ago, Pete Lewis said: frequency of the clatter engine related or prop rev related ?? pete Or simply speed related? Something blowing about underneath when over a certain speed? Make sure it's not the rad moving back into the fan and hitting the blades as air resistance pushes it back - check everything that might come into contact with fan blades.

Iain T Posted February 6, 2020 Report Share Posted February 6, 2020 I would take gearbox cover off and check arm operation engine off and on, car stationary. Is there a rattle and if so does it go away when the clutch is operated? You can hear better with the cover off and then take it for another spin to see if you can identify where the noise is coming from, if you are in 3rd and low revs then accelerate does the noise still occur?

Iain Hi Iain pretty sure it was ok in third accelerating , issue seems to happen when it’s under load ie 4th haven’t been able to check overdrive yet . Will remove the cover and test drive again Paul Link to comment Share on other sites More sharing options...
Iain T Posted February 6, 2020 Report Share Posted February 6, 2020 Those out there with Triumph gearboxes is it normal'ish to have a noise/gear rattle under load at low revs in top? As I said given the same conditions my type 9 (rebuilt and uprated by BGH last year) rattles and if I remember my XR4i did. Iain Link to comment Share on other sites More sharing options...
johny Posted February 6, 2020 Report Share Posted February 6, 2020 No the gearbox is pretty noisy if driving with the cover off but once on I dont get any rattles loud enough to hear. How about getting the car securely up on axle stands, then get it in 4th and have a listen.... Link to comment Share on other sites More sharing options...
