1969 MGC GT Speedometer Angle Drive Repair
Вставка
- Опубліковано 5 лют 2025
- My speedometer, odometer, & trip meter suddenly stopped working in my 1969 MGC-GT. The fact that it quit suddenly instead of gradually, made me suspicious it was a problem with the cable not turning rather than an actual instrument failure. I discovered that the angle drive which connects between the transmission and the speedometer cable had literally blown apart. This video documents finding the issue and replacing the angle drive.
Great video again Today Ken of you fixing the speedometer of the angle drive repair well done for getting it mended Keep up with the good work Ken 👍 And I can not believe it is The 3rd Day of Autumn already in the United Kingdom
Thank you for watching. Autumn, finally. Was in the high 60's (F) all day today. Love it.
Your Welcome Ken I Really enjoy watching your youtube videos and putting a comment on every video Well Autumn is Great in the United Kingdom From Tonight The United Kingdom Has got a Weather Warning for Heavy Rain from 21.00 until 23.45 Tomorrow Night the United Kingdom has had the coolest Summer since 2015 Keep up with the good work Ken 👍
Hi Ken, based on the damage "hit" marks on the old unit, and views in the video of both it, and the new one, installed, the car likely has failing engine and transmission mounts, which are allowing the tail of the transmission to sit too low, in the proximity of the chassis cross-member. This is allowing the angle drive to strike on the cross member, either when the clutch is being let out, and/or during acceleration or deceleration, or when going over bumps.
Thank you for watching and taking your time to comment. I will check this out.
@@kensshowtell A 1:45 in the video, there's an excellent shot of broken angle drive, sitting very close to the flanged lip of the cross-member, and if the video is paused, the resolution is good enough that plier jaw marks are seen to the right, where a pair of pliers has been used to bend the flange downward, out of the way of the tail cone of the overdrive transmission. But in the area of the angle drive, this was not done.
If it were mine, and since I'm not flying it to the moon, I would "fold" that entire flange, down and completely out of the way. If that didn't provide the clearance I thought was necessary AND the engine and transmission mounts didn't look like they were aging and sagging or torn, I'd probably use large diameter fender washers, to shim the transmission to sit higher up into the tunnel. A single washer between the base of the mount, and the frame of the car, or between the trans and the mount, might be all it would take.
@@austinado16 Thank you for looking at my video in such detail. I see what you mean. I know it is possible for the rubber in the engine and transmission mounts to sag or be compressed and still have a smooth and vibration-free ride. My 1954 Chevy is occupying the lift space right now waiting on her annual service. When I finish that job, I will move the MGC over there and take a look. Again, I value your observations.
@@kensshowtell Happy to help Ken. My training is in diagnostics, so I'm always looking for the cause of an issue.
I don't know the history of your car, but is it possible that it wasn't originally equipped with the overdrive transmission and that was put in later? I ask because of the clearance that someone created by using pliers to bend that flange on the cross-member out of the way. Maybe initially that was all that was needed, because fresh engine and trans mounts created sufficient clearance.
Looks like it'll be easy to remedy, especially since you have that sweet lift.
@@austinado16 The car was completely restored in 2009, and the overdrive transmission was added at that time. You have an excellent eye for detail.
Well done fixing it mate ! lucky the service notes about the washer came with it ;-)
Thank you for watching and your lovely comment. Yes, it was originally a factory bulletin, but Moss discovered that mechanics and owners were unaware of this, so they decided to include this little gem.
