SPEEDOMETER WITH TWO GROUPs OF GEAR
"IN FINE" I think that the explainations of ROB are right and the speedometer owns differents meshs (gear) . Inside the speedometer one group of mesh would be engaged when the truck is in high speed and the other group when the truck is in low speed.
Unfortunaly the truck of my friend is in BELGIUM and the pics showed at the begin of these thread had been shoted on and other truck which original speedometer has disapeared.
I will ask other information about the speedometer to my friend.
MLU forum is a wonderfull mean to understand what the old mechanics knew
Thank to all
