Picked up some lovely Z1 MCRs recently to put on the Univega ( or maybe the UFO as its still with me )

SAnyhow..can;t seem to access the manuals on Marzocchis website and was wondering if anyone can help with instructions or possible problems and repair.

The lever appears to do nothing.

In fact any help with service/maintainence would be appreciated.

Regards

K

ECC is extension control circuit. It's essentially the predecessor to the ETA (extension travel adjust?) but works the opposite way round. The ECC works by restricting the oil flow on the rebound circuit so when the fork is compressed and the ECC is on the oil can't flow back through the circuit keeping the fork locked down. That’s all from memory and it's been a while so I could be wrong...

I'm guessing one of two things is wrong:

1. There's no/not enough oil in the cartridge/leg.
2. I think there's a little grub screw that locates into a slot on the cartridge shaft. Sometimes they unwind and allow the adjuster to just turn (the slot normally limits the movement to about 90degs).

I'm guessing 1 is the most probable because if 2 was the case then it would lock-out at some point in the adjustment range.
