Manual Transmission Clicking Noise

Posted by TimE On 2021/1/25 14:21:55

Hello fellow enthusiasts, so I have had my 41' Clipper for nearly a year and have been working on getting the car road worthy since I purchased it. The car has not ran since approximately 93' and is now a fantastic running and driving car. Now for my problem, the car has an annoying ticking noise at idle, in 1st and 2nd gears while driving. I can't tell if the noise is present in third. The noise goes away when the clutch pedal is depressed and will resume when released. I removed the transmission, inspected every gear and bearing and only replaced the clutch shaft bearing and driving shaft assembly due to less than ok preload and slight roughness, everything else looked perfect. Unfortunately this did not even change the noise for the better or worse. I have since used an app to determine the noise frequency, calculated the speeds of every rotating transmission component in relation to engine speed measured with a tach and found the noise to be at the exact speed of 1st gear on the driving shaft. This was already replaced so I'm a little perplexed at this point. I also calculated the possible bearing fault frequencies for every internal bearing and the only one close is the cage for the pocket bearing between the clutch and driving shafts. Any thoughts or cases of this on anyone's car?

Thanks in advance,

Tim
