daverclasper Posted November 1, 2017 Report Share Posted November 1, 2017 Hi This is quite loud with gearbox cover off. Starts at about 1200 rpm. Does it in all gears (not sure about reverse) and also in neutral if the engines is revved up a bit. Gearbox was rebuilt by Mike Papworth about 6,000 miles ago and not had hard use. Any ideas? and something I should look at sooner rather than later? (prefer not to have to take G/B out really). Any help great please.

Pete Lewis Posted November 1, 2017 Report Share Posted November 1, 2017 does it do this if clutch is depressed ??? Pete Link to comment Share on other sites More sharing options...
Steve P Posted November 1, 2017 Report Share Posted November 1, 2017 My 2.5 engined Vitesse with saloon box makes a sort of sigh or groaning noise when the clutch is depressed,that`s after 10000 miles use,weird. S Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 1, 2017 Report Share Posted November 1, 2017 Thats down to the throwout bearing or clutch fingers Pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 1, 2017 Report Share Posted November 1, 2017 Dave have you eliminated its not engine ancilliary noise, fan belts etc. Pete Link to comment Share on other sites More sharing options...
daverclasper Posted November 2, 2017 Author Report Share Posted November 2, 2017 Hi and thanks. Noise seems to be from bell housing area and is almost a squealing noise, have noticed it's there a bit at idle in neutral as well. Very gentle pressure on the clutch pedal and it stops (my clutch disengages quite high up the pedal travel, since I fitted one of those very cheap Landy M/C) whether in neutral on driving along.

Pete Lewis Posted November 2, 2017 Report Share Posted November 2, 2017 If it stops with a light touch to the clutch pedal then its a noise from the throwout bearing This can be the bearing is in trouble , but it is often the diàphragm fingers skidding on the throwout bearing The drag of the bearing is greater than its grip against the fingers and you get squealy chirruping noises As the noise improves with a touch its not the bearing , that would get noisier if the bearing race was in trouble With foot off the only pressure applied is from the spring inside the slave Its not uncommon , but is annoying, if you pull the throwout lever back a little the niose will stop A heavier spring inside the slave would solve it, as would go back to old days and have a slave pushrod with some free end float, Having rambled about that if the squealing Does not Stop when the pedal is depressed it will need likely a new throwout and maybe a new clutch cover Link to comment Share on other sites More sharing options...
daverclasper Posted November 2, 2017 Author Report Share Posted November 2, 2017 Thanks Pete. That's great info. Noise, not too bad with G/B on so will leave it, unless it gets worse. Unless it is slowly causing wear/damage to diaphragm fingers etc?. Also is the throw out bearing also called release bearing please. Cheers, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 2, 2017 Report Share Posted November 2, 2017 Yes one and the same thing. Unfortuneate but many clutch withdrawl designs are not the best Skidding release will in time wear the fingers, as will wobbly carriers and misalignments the wear makes a groove in thenfingers and the release has to ride out of and pedal loads start to get heavier Something you won't get with a coil cover as there is a platen the release runs on not hard steel wonky diaphragm fingers Pete Link to comment Share on other sites More sharing options...
daverclasper Posted November 3, 2017 Author Report Share Posted November 3, 2017 Thanks Pete Chirruping noises is a good description of me driving along in my Triumph Aviary. Just a couple of questions please You mentioned the older slaves with some push rod play. I imagine the bearing would only be in contact with diaphragm when you press the pedal and this would cause less wear on bearing?. These slaves will be hard to get in ok condition I imagine. Any way of modifying my current one?. Or, would it be fine to fit a heavier slave spring, though I imagine the bearing would be turning all the time (years ago a mechanic told me about premature bearing failure, due to folk leaving there foot resting on the clutch pedal). Any ideas where I would get a spring from?. Sorry, that was more than 2 questions and hope I'm not banging on about irrelevant stuff. Thanks again, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 3, 2017 Report Share Posted November 3, 2017 Having the release turning at engine speed all the time is quite normal design from then70s to present day Resting foot used to destroy a carbon release which had no moving parts just a carbon thrust face. You could arrange a light external pull back spring on the outside of the lever but needs a stop to control a minimal pull back Or you loose pedal travel, taking up the 'slack' Look at the design of morris minor as a example Pete Link to comment Share on other sites More sharing options...
daverclasper Posted November 4, 2017 Author Report Share Posted November 4, 2017 (edited) Thanks Pete. Would like to go for the simpler job of a heavier S/C spring. I assume that's the conical shaped one?. Any clues where to start looking for that please?. Use car for work, so not ideal to strip it to get an idea of size at the mo.

Pete Lewis Posted November 4, 2017 Report Share Posted November 4, 2017 Apart from browsing slave kits to find some alternative, its turn the radio up Drop the windows and let her sing A light bungy strap hooked over the arm to load a bit more contact might be a simple way Might even get that on from under the bonnet...hook the pushrod. you have to join the bodgers club Or load the pedal with a elastic thingamyjig sorry just dreaming up out the box solutions It wont take much to silence it Pete Link to comment Share on other sites More sharing options...
daverclasper Posted November 4, 2017 Author Report Share Posted November 4, 2017 Cheers Pete Don't mind the noise. Good bodgery fine by me. Trying to prevent G/B out and expense for clutch repairs is main concern. Thanks, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 5, 2017 Report Share Posted November 5, 2017 Ot doesnt take a lot of load , if you just apply a little hand pressure to the pedal it will stop the chirruping A light spring, bungy, peice of old inner tube to pull it into contact is all you need to keep it spining Nothing heavy , or you can load the crank thrust washers , just needs enough to dechirrup the chirrup. Later on you can have the box off and examine whats going on at your leisure, not that anything will show up Apart from a bit of finger wear.

Paul H Posted November 6, 2017 Report Share Posted November 6, 2017 My Vitesse has developed the Chirrup noise coming from the gearbox housing, checked and with pressure on the clutch whilst driving it stops - i did observe that with deceleration the canary is more audible - the slave cylinder is a NOS and only been in for 3 months . Is it feasible to use 2 springs in the Slave Cylinder ? Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 6, 2017 Report Share Posted November 6, 2017 No idea, You could as another out the box idea add a coil, spring to the pushrod to press the lever away from the slave there by adding small loads to the chirruper.

daverclasper Posted November 6, 2017 Author Report Share Posted November 6, 2017 Cheers Pete , and many thanks for your always good ideas on alternative ways of doing stuff. Like the spring to the push rod idea. Will give a go if can find suitable spring. Thanks, Dave Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 7, 2017 Report Share Posted November 7, 2017 there is always a way just not always acceptable can range from bizare to clever ,, There a preference here between how to solve a problem and the likes of originality Pete Link to comment Share on other sites More sharing options...
daverclasper Posted November 10, 2017 Author Report Share Posted November 10, 2017 Hi Pete, I have fitted a fairly low tension spring to the top of push rod (It's an interference fit, though can be adjusted up and down, by twisting the spring, if that makes sense). It is currently only about 2mm proud of tip of pushrod, though has silenced the Canary on a short test drive. Won't likely have put any load on the crank thrusts will it ?, do you think (as a bit paranoid of this). Thanks, Dave Link to comment Share on other sites More sharing options...
jamesdennison Posted November 10, 2017 Report Share Posted November 10, 2017 Dave, I have exactly the same issue ... may have posted on here about it ages ago. I was toying with the idea of something to take up the slack on the clutch pedal but if your solution has worked it sounds less like a bodge. Is there any chance you could post a pic of what you've done on here? I think I know what you've done, but always useful to see! Thanks.

Pete Lewis Posted November 10, 2017 Report Share Posted November 10, 2017 The sort of fairly minimal loads to silence the chirrups wont adversley effect the thrusts Riding with your foot on and partly depressing the fingers would, youre not going that far You could be onto a wonder cure sold as anti chirrup device Ha Pete Link to comment Share on other sites More sharing options...
daverclasper Posted November 10, 2017 Author Report Share Posted November 10, 2017 Hi Your idea Pete, thanks. Wayne. I'll give it some more mileage (maybe disturbing the arm, S/C cylinder has masked it temporarily) and if necessary adjust the spring position and see what happens. Will keep this thread posted. If it seems to have worked will try and put photo on. Dave Link to comment Share on other sites More sharing options...
daverclasper Posted November 13, 2017 Author Report Share Posted November 13, 2017 Hi Wayne. Done another 30 miles and still no noise, so hopefully a fix. Will try some pics. The first is what's on the car with the spring a tight fit (on a fairly new push rod, which is a tight fit. Second is an older spare, which is a bit thinner, so used 2 spring. you could fit a spacer to get the right length. Was surprised how little spring load has made the difference.
