The Stovebolt Site Forums The Shop Area Driveline clutch adjustment

I probably need to adjust the clutch on my 61 GMC half ton with the 305. it doesn't take hold till pretty close to the top and I certainly am not looking forward to trying to replace it. can any free travel be felt with the hydraulic slave cylinder setup or should I just see if I can back any adjustment off till it hopefully engages at about half travel? I have in the past adjusted mechanical linkages but I know later model hydraulic clutches on Fords I have owned were pretty much self adjusting with no adjustment available best I remember

I have found it more difficult to adjust a hydraulic clutch than a mechanical clutch. You should be able to get under the truck and make sure that the through out bearing is not against the fingers on the pressure plate when the pedal is at rest.

Like Don says its best to check the freeplay at the slave cyl. You should have about 1/4 in freeplay in the fork. Its best to pull the rod out & clean up all the threads so the adjustment turns freely.

I'll try to get time to get under there this afternoon and get'r done. I replaced the rear springs yesterday. one side was a bear to get the old one off- plenty rust /broke bolt, broke spring etc. other one came out pretty good- likely it had been replaced sometime. it was a different diameter than the left one. I put a set from a late 60's I think back in. they were a little thicker and larger diameter and 2" shorter than the old ones, but I made a spacer spool to make up the difference. it stands up straighter and holds weight better now. probably too 6 hours or more labor but well worth it. I'm gett'in there.
