Manual trans dilemma
I have a weird problem with my ‘60 F-100. Last weak my slave cylinder gave up the ghost and today I swapped in a new one. I thought it would fix another small problem I have always had but it did not. The truck shifts fine while driving. If you shift into neutral and leave it in neutral for an amount of time longer than it takes to shift between gears it will grind trying to bring it into any gear. My adjustments are where they should be. I am now thinking pressure plate. It has been like this since I bought it in ‘17.

Re: Manual trans dilemma
I'm thinking pilot bearing/bushing. I don't see how the pressure plate would cause the issue. Either way it requires dropping the transmission. Once it is out at the very least the release bearing and the pilot should be replaced. If the fingers on the pressure plate are warped or weak then you might as well replace it and the clutch plate.

Re: Manual trans dilemma
I also am leaning towards the pilot bearing/bushing.

Re: Manual trans dilemma
I'm leaning towards Alaska Jim's thoughts. If you pull the trans to check the pilot bushing/brg, take a close look at the trans front Brg retainer. Badly worn pilot bushing can put stress on the retainer and crack it, as the input shaft is not being held in proper position. Ask
me how I know this! |

Re: Manual trans dilemma
Something is allowing the main input to turn when it should've coasted to a stop with the clutch disengaged. The pilot bearing would be the most likely cause if the clutch is in fact fully disengaged.

Re: Manual trans dilemma
When sitting in neutral with the clutch pedal out and engine running, you must give the trans time to slow down when you step on the clutch pedal. All that stuff in there is running at 5 or six hundred RPM's. Then, push gently towards second gear and then pull to first. I hope you don't have to pull the trans.

Re: Manual trans dilemma
Thanks for all the replies. Pilot bearing makes sense to me. The trans is in need of a good gone through so maybe this winter it is time to do that. I will let you know what I find. Clutch master is also old and that will be looked at as well.

Re: Manual trans dilemma
I agree that it is old but I drop it down into first when I come to a light or long stop and keep my foot on the clutch pedal. If it was slowly releasing the truck would start to go forward which it does not. Something else I beleive inside is dragging and the bearing is a thought I did not have.

You need (IMO) to lie underneath and have someone depress the pedal. Ascertain if there is a correct air gap between the flywheel, disc and plate (or if the disc is warped). I would do that before pulling the trans.
