Hey, Geoff.

Hows that CY-50 going, has it still got original grey motor & what year is it.

I have a CYF-50 (Friction clutch) converted to CY-50 (Torque converter) , I got the original build card from clark USA, it was built in 1964 with Holden greymotor. It now has a 186 red motor. Mine also has short mast, I can only just load onto top of container.
I had lots of problem with slip when hot. Ended up being the floor pan modification ! The brake pedal was not returning enough & when every thing was hot the master cylinder pushrod had negative clearance & was activating the inching valve.
So bashed th floorpan & adjusted the pushrod & now all is sweet.
