    Could use some help please.
    I have to push the clutch pedal all the way to the floor, and wait for the trans to stop spinning, to get it into gear.
    I do not see a clutch brake
    I do not see a way to measure for a half inch gap between throw up bearing and clutch brake. Is this clutch even adjustable? I do not see a 5/8 adjustment bolt head.
    Do I just adjust the linkage ?
    I have about 1" play at the pedal.
    It's a real drag driving this truck in town.
    Also- is the switch missing a knob on shifter the LowLow switch?

    Looks to be a standard 8 sp, just 1 ‘low’ gear. The clutch style generally corresponds to the make of the truck, not the transmission. Go to YouTube and search for ‘clutch adjustment on___________ truck. They’re all kinds of videos for all kinds of trucks. Some trucks require 2 people to properly due a clutch adjustment.

    Crawl under the truck, and get the model number stamped on the curb side of the transmission, research that number and you will know exactly what you have.

    Big trucks normally have a pull type pressure plate and small trucks normally have a push type pressure plate. You have an in between sized truck and it can go either way. Yours has a pusher and they have no clutch brake. It should still have an adjuster in the pressure plate. Bump it around to find the adjuster. Have someone hold the pedal down and turn it to get some free play. Adjuster could be what you have taken pictures of with a bolt on each side . That one is new to me.

    It has the same 2 bolt plate in 4 places. I see nothing to adjust. I did rotate the clutch.
