Got the new gauge face today, well packaged and overall I'm really impressed with the quality !! I got the face fitted today but not after some drama, which I could have probably avoided if I'd read a bit more before starting.
Minor issue: I'd got some chrome bezels from a 330 cluster some time back and was waiting for this job to install them. Didn't realise they were only held in with some mastic it seems so need to source some to fit them permanently. No biggie.
Major issue: Managed to break 3 out of the 5 stepper motors when removing / installing the needles 😭 After much researching it seemed this was a common issue and I just needed to be more careful with the removal / install. Conveniently I have 2 spare clusters (one from the bezels and one for my CAN development) to rob parts from !! I tested the one which was still complete and all motors worked well ... considered using that whole cluster and doing the EEPROM plus coding thing, but that seemed like another layer of drama I'd prefer to avoid, and I still needed to remove / install the needles.
What I ended up doing was removing all 5 stepper motors from the good cluster and swapping them into my otherwise good board. Turned out to be incredibly easy and everything is working perfectly again !!! Top tip was to use compressed air to blast out the liquid solder instead of using a wick or sucker.
General & pics: As I'm driving the tacho via my Arduino it was relatively simple to re-calibrate this to suit the new RPM range.
I also fixed up the left hand stalk which has never clicked 👍
