Tachometer Cable

[93Bandit]

Not sure which section to post this in, so I'll start here. Are there any tips to keep the tach cable from unscrewing from the head? I've tightened it multiple times but every time I check it, it's loose and theres oil seeping. I'm getting tired of messing with it. This is on my 850 by the way.

Is there still an Oring in there?

Replace the seal in there - procedures are on either Basscliff's or BWringer's websites. Also get a new cable

I usually add an o-ring inside the fitting.

Not for sealing, and this isn't the sealing band or the seal. The o-ring just gives the fitting something to "squish" against and keeps it from vibrating loose.

Just rummage through an assortment and find a size that will go inside the fitting on the head and stay without falling out. Then screw in the cable and carefully give the fitting a little extra tweak with pliers and it should stay just fine.

Also, OEM cables seem to work a little better in this respect. The aftermarket crap is not very well made and fits a little loose.

It's a new cable and it's aftermarket, so a crap loose fit is probably the issue. I'll try the o-ring method.

I have used aftermarket cables before, with few problems. They do loosen up, unless you have them REAL tight. I use channel-locks to snug them up real tight, but then there is the problem of trying to loosen them when you need to. I just replaced the cable on my son's bike with an OEM cable, we'll see how it goes.

As far as the oil leakage goes, there are two seals involved. One goes around the housing to seal against the head, the other goes inside. It looks a lot like a valve seal, but seals against the cable itself.

I've used channel locks the last 3 times but it still loosens. If I grip it any tighter I fear crushing the sleeve. I'll make sure both seals are in place.

Consider using blue Loctite.

Consider using blue Loctite.

Don't do this. The sleeve is very thin metal (at least it was on both the OEM and MotionPro cables I have) and you probably wont be able to get enough force to break the blue Loctite without first breaking the sleeve. And getting the remainder of the sleeve out of the threaded portion of the tach cable insert is not fun, trust me.

Loctite makes red, blue, and purple thread locker. The red is high strength, blue is the medium. The purple is a low strength, it might be suitable for this application if the blue is too strong.
