Hi, I have difficulty changing gears, especially from a start. It feels like clutch drag to me, but the mechanic said "it's definitely releasing." He thought it could be a transmission lubrication or possibly synchro issue, certainly possible. I asked him to verify the clutch release by jacking up one wheel and spinning that wheel by hand while someone presses in the clutch in first gear. He didn't think it was worth it to do that test, so today I did my best to test this on my own.
My procedure:
1. Jack up one wheel.
2. Secure a strap around the tire, and rotate hook to desired position.
3. Place the truck in first gear.
4. Hang a weight on the hook.
5. Slowly depress the clutch until wheel movement is seen.
(This was at about 1.5" before the floor with sufficient weight.)
6. Increase or decrease weight until decent upper and lower bounds are found.
I found it took about 24 lbs of weight (30-35 ft•lbs of torque) to turn the wheel when the clutch was pressed to the floor. If I used anything less, the wheel wouldn't move until I pulled the gearshift lever with what felt like too much force. As I moved it from first to neutral, clutch pedal still down, the wheel would suddenly release, and the weights would fall to the ground.
This definitely confirms that I have clutch drag, but how much is too much?
I used to have this problem before the clutch was changed, about a year ago. It would show up out of the blue, then sometimes slowly go away. This seems to have gotten worse almost overnight.
Possible culprits:
1. Air in hydraulics
2. Worn clutch pedal mechanism
3. Worn throwout bearing (in 8k mi??)
4. Tight pilot bearing.
Just trying to get a sense of how much drag is too much before I crawl underneath the thing and spend who knows how long trying to free the MC in in freezing weather.
Thanks for any input.
