Crunchy gearbox

[apgodden]

Got my car moving under its own steam......  only thing is when selecting a gear it is crunchy..... especially reverse.  I cannot see any adjustments for the clutch cable.

 

Any ideas / suggestions 

 

many thanks Tony

If you're using the Sierra pedal box and clutch pedal, the adjuster is at pedal end. It's supposed to be automatic but sometimes they don't work. 

Have a look and see if there's any adjustment left on the quadrant and also see this:

I had the same problem and built the car with the same pedal setup and clutch from the doner but it never worked well.

I only drove the doner about 20 miles and clutch was good (the car had other problems) so I was supprised that it did not work as well in my exmo.

First thing I found was that the  mounting provided by robin hooh had the cable outer stop nearer to the peddle than in the doner, a stack of washers helped.

Then a couple of years later I came across a stall with a full selection of pawls for the ford pedal and fitted the largest (black as they were colour coded) and it transformed the gear change.

The s7 pedal box is terrible as originally designed and has a lot of flex, enough to cause issues the the clutch not working correctly, no matter how much you adjust it.  Initially i added 2 braces from top of pedal box front plate to the firewall,  which sorted the flex on braking, but then needed to brace the clutch pedal assembly to the front plate too.

I have ordered the Black pawl,  fingers crossed.

 

Many thanks for all the info.
