    Tacho Not Reading Right

    My tacho on my R160 has recently started reading low. Sits about 10mm below zero when idling, was reading about 1800rpm at idle before this shit started . Still works just not reading right. Anybody have this problem before.
    Done a search couldnt find any info.
    Looks like another call to FX on Monday morning. Must be getting fuken sick of me ringing with problems.

    Gonna start leaving it in bad neighborhood overnight hopefully some one steals it.

    Sounds like the needle has slipped on it's spindle.
    Easily fixed.

    I'm assuming the TNT dash is similar to the Tornado. If so, there are two allen head screws on the front, and six pozidrive screws on the back. Remove them all and separate the two halves.

    Don't use a phillips head screwdriver on pozidrive screws. They don't play well together.

    DON'T TOUCH THE DIAL FACES. If you get oil from your skin on them, you won't get it off.

    Make up a thin cardboard cover with a thin (1-2 mm) slot in it to slip between the tacho needle and the face. With your finger nails, gently lever the needle off it's spindle. Yours should already be loose, but if not, and the finger nails aren't up to it, use two small flat screwdrivers and the two face screws as fulcrums.
    Once the needle is off, just slide it back onto the spindle lined up with zero.

    I've just opened up PKRS' dash. It was sealed with black silastic which needed to be carefully cut with a scalpel.
    To get the needles off this time I tried just spinning them anticlockwise against the stop while pulling upward. They came off much more easily than trying to lever them straight up.
    With your tacho needle, once loose, simply rotate it all the way around to 0, then push it back home.

    Thanks mate.
    How the hell do I get the tacho out from behind the alloy dash cover. I've got the plastic covers off and the two Allan bolts out from each side but where do o go from here. Confusing.

    I can't help with that bit. You'll have to wait for someone with a TNT to tell you.

    Anyone?
