Dry Clutch Problem.
Hey guys,
Just after abit of advice.
Bought a Shovel with a blown gearbox (1976 FX) its got a dry clutch, with an open primary, no starter. I've bought a second hand 4 speed and mounted it. Swapped all the bits over clutch kicker and all, (bike came with no clutch cable) installed a clutch cable (supposedly oe part, length and all) but I cannot get the clutch to function at all. If the springs are set and the clutch adjustment screw is screwed all the way in till the clutch arm is pushed all the way back then backed off half a turn. Pulling in on the clutch arm doesn't give any movement what so ever. There must be something I am doing wrong. Inside the kicker cover the lever and all seems to be all aligned to the clutch rod. I believe all the clutch plates are in the correct way. Spring measurement should be pretty correct although I have a weird putter pressure plate different to most. But even then shouldn't there be a tiny bit of movement like the clutch is semi functioning? Just an fyi that the clutch was working fine when I pulled it off. Even though the gearbox was cooked the clutch still functioned.
Please any info would be highly appreaciated. Ive been going at this for a few months haha. I also have a workshop manual and it has hardly any info on this.
Thank you for your time,
Arlo.

usually the first adjustment is to get the clutch arm 5/8" from the starter so the lever inside the kicker cover is correctly aligned with the throw-out bearing. without a starter, IDK how you would verify that, but it's important, because the other adjustments work off that.
not a lot of help but that's all I got. hopefully one or two of the experts will answer soon.

the throw out bearing might have turned and not in the slot and now your pushing on the bell sideways
pull the kicker cover off and post up pictures if you need to many on here can help

The same clutch works fine with a sealed primary..long as you only put enough oil in to get some on the chain!!
As stated...even in the Good book... the Lever must be at optimum Angle...really the Fingers against the Throwout Must be at the correct angle of attack...to get proper function... You must start with the Lever at the correct position...and then proceed.

All Shovelhead clutches are effectively Dry... By Design... the Oil is drooled onto the chain [as stock] and sucked out at the back of the primary..
