anybody had this problem

I had no idle for weeks ..stepper reset would not reset it

anyway took it apart today

and it appears that the pinion gear has come loose on the stepper shaft - the shaft no longer turns the gear

I'm going to try and glue it on with retainer glue - obviously all will be cleaned before i do it - opinions?

The torque loading is high for such a thin shaft, two strong springs each side of the butterfly. I've greased the snail cam and plunger lightly.
on advice from friend I wheeled the shaft between two files to raise knurls ...then added the high strength glue .and pushed it on - I could feel a bit more resistance as I pushed it on
Now I wait for 24 hours, before putting it back together ..crossed fingers , arms , legs etc

all the best..mark

I’ve not come across that before - I hope your fix works ?

The car is now 24 years old - and had an amount of furred up alloy inside the housing ..must have got on the pinion and caused it to strain a bit ...so maybe as a 20 year service item, its worth taking a look, giving mechanism a clean and adding small amount of grease.- before you have a large bill for a new stepper motor .
