Stuck Tachometer cable

(1/3) > >>

Greg65:
Hi all,

I have a noisy cam chain so need to take the engine out. The tacho cable is prooving reluctant to leave its current location. I have removed the screw in the engine but can not remove the cable, I have tried some heat from a hot air gun and have left it covered in WD40. If this fails and I disconnect the tacho from the instrument and then remove the engine followed by the cover, is there any risk of damage to the drive? Failing that any other hints.

Thanks for all advice.

It normally just pulls out, like the speedo cable.  It's obviously corroded in place.   Heat, oil and pliers should shift it.

Chris400F:
Agreed, corrosion is most likely your problem as once the screw is removed there is nothing else holding the cable in place.
I wonder if gripping the metal part on the cable end and trying to rotate it might help free it.
The cable end is round, in a round hole, so it should be able to be turned when not fixed in place.

Steel in Al alloy....cable in place for years and years plus hundreds of hot/cold cycles !
Plus Gas then gentle turning with pliers.
They often weep oil past the drive seal which can help prevent them sticking.

Thanks for that. Finish work late Saturday so will give it another spray with WD40 and see what I can achieve Sunday.
