variety of OM617 tachs
variety of OM617 tachs
the numbers visible on the two tachs are: 230/154/1 14000Hz, on the one i was cutting up; and 230/107/15 6000Imp., on the one from a cluster which is elsewhere stamped 1982. unfortunately i don't know where the butchered one came from.
do these two units work the same? the numbers 6000 and 14000 sure make me wonder.
cheers!

hi folks, i was butchering a five-cyl tach to convert it when i noticed that the other one i had on hand was different. the VDO part numbers differ as do the signal jacks and circuitboards.

I imported one of those, and bought a VR sensor (for a 6BT) myself but haven't quite got to the stage of seeing if it actually works yet...

The one with 14000 is meant for '84-'85 cars with EGR computer. They had a VR sensor on the flywheel with ran off the starter ring teeth. You can bypass the EGR computer however.

thanks Scott! since i don't have the flywheel sensor, i guess i need an older tach.... cut up the wrong one. onwards and upwards!

If i remember correct i took a w124 or w201 diesel tacho and installed it in the w123 cluster 1 year ago. Had an om606 in that car from a w124. Only drove some km with it before i sold it.
