Intermittent Speedo repair?

[saint]

My analogue speedo jams every 10mph until I whack the binnacle. The digital one is fine.

 

Assuming something in the mechanism is missing a tooth, what's the chance of getting it repaired? Is it better just to replace it (lee?) and if so won't that mess up the cars reported mileage?

No teeth its a direct drive dc motor.

Needle probably come loose on shaft or similar.

It all screws together if you want to take it apart and see..

Fully working pre owned are in stock and if you are concerned about mileage then digital mileage correction will fix that issue.

 

Just drop me a PM if I can help further.

Its all in bits, anything to look for specifically? I've moved the needle with my finger and it feels the same as the others...

From an archived post:

 

"One thing to note is that the 350z has cross-coils to move the pointers, not stepper motors! If you have the meter upside down for over 15 mins then you run the risk of the silicone inside the cross-coils running out. The silicone is used to dampen the movement of the pointers and enable a smooth operation. If the silicone runs out then the pointers will not sweep correctly and show eradic movement."

 

Possible culprit but google offers no advice. Guys?

cross coils,

motor,

magnets with wires,

etc etc

 

All the same sort of stuff but no teeth on gears was the point.

Needle fits directly onto the rotating shaft out of the motor bit.

Ah fair enough, well the needle was on properly and didnt have any sticking points when I moved it manually. I guess somethings up with the motor unit then.
