Clutch fork greasing (chirping sound!)

Hey guys,

Wondered if anyone else has suffered with a high pitch chirping noise coming from the clutch fork/slave cylinder contact.

Before people jump on the wagon of saying I need a new clutch, throw out bearing, input shaft (seems to be the consensus when I searched originally) the clutch was replaced about a year ago when the gearbox was rebuilt and I've never had any issues with shifting and I'm positive it's coming from the clutch fork area.

Originally I tried greasing up the pivot with copper grease but given a few weeks the noise just slowly returned. I then thought I would try a high temp grease (the sort you use on caliper sliding pins) but the clutch just creaks when you put the pedal down. Just as irritating!

The manual says to use Urea grease and that I should be able to get this direct from Honda. Is that my best option? And secondly should I be greasing the pivot point of the clutch fork just inside the gearbox housing also?

Can't remember the brand of clutch but the guy who rebuilt the gearbox used to do a lot of maintenance for Honda, and he was happy with the clutch I supplied. Remember having to choose from two brands and the one we used was down to him inevitably.

In regards to the tapping/chirping It doesn't do it when the engine is off as its caused by the clutch fork tapping against the slave cylinder when the clutch is out. Doesn't change dependant on speed. However with the high temp grease it creaks if you push the clutch in regardless of whether the engine is running.

@mercutio not sure if you had mistyped but I'm happy with the clutch and think it's simply down to a lack of grease on the clutch fork pivot points

We had that on the Accord. I think it was due to the assembly being too clean. The release fork and pivot both need a bit of grease.

Any thoughts on the grease I should use? Seeing as copper seize and the high temp stuff hasn't worked out :(

So this is after you've released the clutch, not when you've got your foot on the clutch, right?

Exactly right :)

The green Honda urea grease should do it if it's the pivot ball. I think I used graphite bearing grease on a similar job ages ago.
Also, there might be a small pip on the ball which won't help. It can be filed off - gently.

Does the noise go away with the slightest actuation of the pedal, ie: taking up the slack?

If you push the pedal just a hair in then the noise disappears entirely. Before any resistance is felt through the pedal. I'll probably give the urea grease a go - after all it's what is recommended. ideally just need a grease which doesn't thin out and sticks there!
