I just installed a new 168 tooth flywheel and clutch kit in my 1965 C10 with a T5 transmission. I am really enjoying the new parts. The clutch engages smoothly. For years now, the clutch I had would shudder occasionally when taking off from a standstill. Apparently the pressure plate was not doing the job properly.
Last week I damaged my old pressure plate. I had removed the pressure plate and clutch disc when I changed transmissions and accidentally installed the clutch disc backwards when I put everything back on the fly wheel.
I realized my mistake before trying to drive the truck, but the damage was already done. I then removed the pressure plate and clutch disc and installed everything correctly. However, the pressure plate was damaged enough that I was not getting complete release of the clutch disc. That meant the transmission input shaft stayed energized even though the clutch pedal was depressed. If I wanted to change from a forward gear to reverse, I needed to shut the engine off, shift the transmission, and then restart the engine.
All new parts now and it’s a lot better than before.
