Where do these get rusted up at? We sprayed lube up inside on the release bearing area, Helped some but not there yet. Thanks, LB 79 GMC General with Cummins
That's not a hydraulic clutch is it? If it has a cable I'd lube that, before I'd spray any kind of lube inside the clutch, unless you've got a good view to see where you're spraying, but if you had that good of view I wouldn't think you'd be asking.
Could be the pivot shaft bushings in the bell housing,,, there should be a grease zerk on each side where the shaft goes thru. Also make sure the spring is still on there where the linkage hooks to the pivot shaft.
