  • clutch adjustment.

    I have a 29 , all stock but 12 volt conversion. have just completed a 500 kilometre road test, back a year or so ago while assembling this project when it came to clutch I replaced disc and bearing . I made a finger adjustment tool as per Toms specs. everything operates smooth , no slippage . My issue is , seems like clutch pedal is off floor almost 1/2 to 3/4 of its travel to engage . by depressing clutch pedal while engine is working clutch will slip when pedal is pushed 2 or 3 inches.bit long winded on description ,but this doesn't seem right but is it a finger thing or linkage or?

    How much free play do you have at the top? Is it disengaging the trans well?

      disengages with 2 inches of movement. just seems like to much movement from bottom to when it engages.

    It seems you are describing a narrow 'friction zone'
    However, the main question to me would be, Does it grab when engaging? If not, it is prolly OK

      I agree, if it doesn't slip, shake, or grab, then it sounds OK.

      yes clutch engages smoothly , No chatter . just seems a little to much pedal travel from floor . maybe be my mind.

    Ok, here is my rule of thumb...Open the inspection/grease plate and watch the throw out bearing and depress the clutch pedal, the adjustment should be 1" (22mm) of pedal before the TO touches the pressure plate fingers. Also, it is very important to have the fingers all the same 5/8-11/16 depth from the PP ring.
    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

      Set your free play as Wiz says at 1”. No grinding or other issues I would roll with that

        TIP# 107: For QUICK, EASY Kclutch adjustment, take out the adjustment rod, drill the Khole in Kcrossbar, where the rod will just slide through. Put 2 Knuts on the rod, on both sides of the Kcrossbar. VOILLE" you have a QUICK/EASY Kadjuster goody!---Suppliers sell a similar Kthing, but this one is KCHEEP!

            Thanks Jeff, I figured because this was just a frame when I built it and the amount of things that can go wrong I would do a bumper to bumper inspection. couple of things need a extra grunt but overall not bad, front wheel bearings a little loose and headlights all cock eyed. clutch seems a little off to me but all in all a great experience .

          Most folks do set the free play at about 1". If you don't like the clutch engaging that high you could try increasing the free play another inch. As long as the clutch will completely disengage its fine. I happen to like a lot of free play.

            so Patrick you are saying that if I increase the freeplay a little it works opposite on the other end ... engage a little quicker?

        • #9
          update . to add to confusion I removed inspection cover , first thing was some grease was around end of T. O. B., No Big deal cleaned up. started engine , bearing not spinning . Free Play.... when pressing clutch peddle it drops about 2 inches ... but ... when at rest T.O.B outer lip has only 1/2 free play. I put this together a long time ago , there is all new parts on linkage with no play or odd movements. tried to take a picture but useless.

            The distance you have from TOB to fingers doesn't really matter as long as it is clear of the fingers at rest. If you are still getting full release at the pedal placement you want, you can adjust the pedal travel to your liking. I prefer to "heel toe" the clutch and when I adjusted mine, I started at 1" and since that released too high I adjusted it so I had more free pedal travel which reduced the distance it took to release the clutch.

            Make it your own, nothing in this adjustment is etched in stone. The 1" travel is there to insure you aren't constantly touching the TOB to the fingers, that's all.

          We adjusted the freeplay at 1" on a V8 clutch (3 fingers) and lightened flywheel, etc. Still had some finger-touching of the throwout bearing.So do as DA Wiz and others state to check via the inspection hole, and also check for adequate spring tension at clutch pedal return.

            update. adjusted linkage so T.O.B is 1/4 inch from fingers. clutch works excellent ,couple inches off floor engages smoothly with no issues.

                    New clutch plate, good pressure plate and flywheel. Worked good before I pulled engine and tranny for freshen up and repairs.i adjusted pp at just .010” over 11/16”.it grinds gears( all new) and if I get in gear, the car is shuddering trying to move, with the clutch pedal in.Right now, the free play needs to be loosened a turn or two on the trunion. The clutch was purchased from brattons about...

                    (Problem Solved) Multi-Disc Clutch Pack
                    by Steve Plucker
                    After assembly of the Multi-Disc Clutch Pack, I have about 1/4 inch movement up and down of the clutch discs within the assembled pack.

                    Is that normal? First time with this.

                    Thanks.

                    Clutch Chatter Diagnosis
                    by 40B1930
                    After 60 miles of shake-down drives, I am hearing clutch disc chatter with the trans. in nuetral. When I press the clutch pedal in to the point where the slack is taken up the chatter stops. After driving the car for a few miles the chatter is gone (maybe the grease on the new throw-our bearing thins after warming)?
                    1. All parts are new
                    2. Clutch disc was centered
                    3. Pressure plate...

                    Clutch adjustment
                    by Greynomad
                    Yesterday, we did a drive of a bit over 120 miles and for the last few before we reached home, the clutch decided to not disengage fully. Gear changes were "crunchy" and engaging first gear at the lights, not so good. I have about 1 1/2" free play in the pedal. The lower lever is the fabricated type and in sound condition (original style replacements are not available for RHD cars)...

                    1933 ford model B 4 cylinder needs clutch adjustment?
                    by ClaudeC
                    Broke down yesterday.
                    In heavy stop and go traffic for 1/2 hour...
                    engine stalled.
                    Could restart easily but could not get the car in gear...very heavy grinding.
                    Had car towed home.
                    Was able to restart and shift gears and drive into my garage.
                    I suspect clutch could not depress enough?
                    any suggestion about adjusting the clutch?

                    Bad clutch??
                    by Tgenardi
                    Just purchased a 1930 Model A with a 1980 Jeep engine and 1939 transmission from what I was told. It may have an adapter between bell housing and transmission. When you put the clutch in, you can change gears, but the vehicle doesn't move. The previous owner said it just went out as she had other potential buyers test driving the vehicle. The clutch pedal is kind of soft.
                    I'm looking for some...
