The oem clutch push rod worked just fine when new, though the weirdass angle that the girling slave was mounted could have definitely been improved upon. I'm working onna prototype bracket for that now that we May end up offering as a service part along with a set of wilwood master and slave assembly for s80 and four cylinder s800.
But your clutch release problem is not related to the push rod unless your push rod is bent, that is very common.
The problem is...your throwout collar and throwout fork are worn way beyond limits.
The "throw" of the s80 clutch release is very poorly engineered, the travel of the girling slave does not match the travel of the girling master, and the leverage of the throwout fork doesn't match anything! Those parts didn't work worth crap on any british vehicle back in the day either!
But we can make this work properly, just like when it was new.
I "recondition" the clutch throwout fork where the tips are worn down. And those tips have caused two badly worn "divots" in the throwout collar. And most likely the oilite bushing in the throwout fork is worn out along with the pivot bolt. None of these parts are available new. But we do offer reconditioned parts that will work as new.
In order to service this assembly, the transmission and bell housing must be removed. Ya wanna replace the clutch disc (at least), and the pilot bearing and throwout bearing at the same time. And rebuild the master and slave cylinders unless they show no sign of any fluid leakage.
Call Jeff at ihon and tell him ya need a reconditioned clutch throwout set for a Scout 80. Then he'll generate an order to me for the stuff and I'll drop ship directly to you. There will be a core charge for your used parts which must be returned if ya want a credit for the cores! I have cores right now that are ready for reconditioning, just place the order!
The set will include a reconditioned throwout fork, collar, and revised pivot bolt.
Here's a pic of one tip (there are two) of a badly damaged fork, yours will look like this one (or worse). The throw out bearing collar will likewise have two divots worn in the slot that match the worn fork tips. Between the two worn parts, all your clutch slave travel is now gone.
If...ya extend the push rod, you will most likely get a few more miles...but then the clutch fingers and cover are going to eat completely though your throwout fork and it will break into pieces, possible get caught in the flywheel and trash everything inside the bell housing. Extending the push rod is just a juryrig that will fail!
hope this helps.
