clicking noise from the instument cluster.
well i guess 463 ownership is settling in. now time to sort out the minor niggles :P
i noticed the slow clicking noise from the speedo area at low speed. it is very slight,but its there.
anyone else had this problem?

i think that'll be the speedo cable (i won't say dirty) but turning with difficulty at low speeds...this runs all the way back to the transfer case so maybe removing the cluster, unscrewing the cable and putting some oil in is advisable?
until more experienced members chip in with the RIGHT way to do it ;)
hi Hus the inner drive cable is probably dry and chafing somewhere along its length caused by hardened lubricant and by the way it is routed from speedo head to the geared attachment on the transfer case....not the easiest.. but the best cure is to remove the cable from the vehicle draw the inner drive from the outer sheath and inspect it for fraying or shiny wear spots... use again if not frayed.. and pump a degreasing agent down the outer sheath to remove all the dead lubricant.soak the inner cable in petrol and let it dry then smear with Sae 90 Hypoid 90 or 80 gear oil and slide it in and out of the outer sheath a few times adding more oil. repeat until you can turn the inner cable by hand and it does not jerk at the other end . do this with the cable laid in a straight line and then in a circle. re-instal making sure there are no sharp curves or tight angles. the oil acts as a lubricant and as a damper and stops the pointer fluctuating.... and eliminates the clicking.......
hmm i'm suspicious, it is like you guys are on cues or something!
how difficult of a job would you rate it, removing that cable from the car? how much disassembly is required..and more importantly, how easy is it to put back? with average tools..
Hi thinking about it!!! you could do the job by getting into the instrument cluster and unscrewing the cable at that end ..do the same at the transfer box.. leave the outer sheath insitu and apply the treatment from the speedo head end. this saves having to reroute the outer sheath but may make a mess on the floor and around the interior with 1.5mtrs of oily drive cable thrashing about....you cannot do the "in a circle" jerk test this way..... while on the subject you can apply the same technique to the bonnet release cable if it is partially siezed... you have to remove the crossmember in front of the radiator to get at the pinch bolt on the catch ......then pull the piano wire out... from inside the vehicle... clean. grease. exercise. and put back......
cheers for that, i think it might make things a bit easier doing it in situ. so the recommended lubricant for the speedo cable is hypoid gear oil, while for the bonnet release it's grease? i find it characterful of old mercs that their speedos bounce at low speeds..
for the speedo cable Hypoid oil does not wax so quickly or run to the lower reaches from the hot spots....grease drags and hardens in the cold...
i guess that's a job i'll do when i change the transfer case oil..while i'm down there. now just the small matter of waiting for some fine fine weather
yess..with the right tools ;) though it makes it much easier to remove the steering wheel before commencing...i hope yours doesn't have an airbag to worry about?
ps. the advice is not completely free..you do pay a membership don't you!
Huss I'd get a 460...lot less hassle. Two Screws and it's out :twisted:
ust a thought....talking without knowledge lol, could you not just disconnect the drive at the speedo head, then pour the oil into the sheath (using a small anywayup oil can) until the sheath is full, ie no free air just oil. i presume the transfer box end is sealed anyway so no leakeage of any degree there?
Its easier to get at the bottom end (one big nut) and I suppose you could draw the inner drive cable out...check for fraying ..clean it ..smear it with hypo' oil and shove it back in the outer sheath... might have to do it a couple of times get the oil all the way up...and do not get any grit on it as that would spell disaster within a very short time...or at least a new cable......
great minds think alike :)
lets see what fixwin has to say. :wink:
