Exup servo motor probs today..

[ogri48]

Had a similar issue a few years ago. Exup valve free as a bird, cables looked fine but changed them for slinky glide ones. Intermittent 7K on the tacho. In the end I bought a second hand servo and fitted it, no more 7K on the Tacho. :woot

I noticed the pulley on the old servo was much harder to turn than it was in the replacement.
Dismantled it and cleaned it up, everything moving freely. Reassembled it still the same.
Pulley would move freely when disassembled, but not when assembled.
Took it apart a few times, but could find absolutely nothing wrong anywhere on the gear system.  :rolleyes
I even tested the motor and it was spinning freely. Totally baffled, I put it in a box in the garage and it is still there :lol

I have the AIS removed which made replacing the EXUP Servo easier.

Take pictures of the way things are routed and how they are located before you dismantle anything.

Cheers mate pics are a good idea. Been laying stone today will give it a go tomorrow, be interesting to see if my problems is the same as what happened to you. It seems to work intermittently, though mike did tell me it doesn't take a lot of resistance anywhere in the system for it to register the fault and essentially put the servo in safe mode. I havnt got a warm garage I've got a cold container....:-(
