Release bearing noise

[dieselDaryl]

I've got the infamous 'chirping cricket noise' coming from my release bearing on my 12HT. I was just replaced the clutch, pressure plate, releae and pilot bearings. It made the cricket noise before but it seems worse now. Is this just an inherint trait in HJ61s? There is no return spring on the the clutch fork like the 3Bs so I am assuming the npoise is from the bearing touching the clutch forks ever so slightly. If I push the pedal in a bit it goes away. It did this before and after the rebuild. Has anyone put a spring in between the clutch fork and master cylinder?

curious, did you install the bearing the right direction? did you push JUST on the inner race when installing the bearing on the sleeve?

IIRC if you put a spring on the slave cylinder it will pull the piston back into the cylinder too far. This will cause you to have too much free play and you will need to move the pedal too far before it contacts the pressure plate.

Yes, the rounded side is towards the clutch fingers. And yes, I used a socket and pressed against the inner race only.

Mickldo: thanks for the verification. I guess I wil have to live with the noise for now. My truck has always done it once warmed up, I was hoping changing the Release Bearing would make it go away.

Might pay to check the slave cyl to see if it bottoms out and has a threaded adjustment or whether it has a floating piston and is adjusted hydraulically. The manual adjustment models need a spring but the auto adjusting models don't have one because of the reasons listed above.

AFAIK all cruisers stopped using the threaded rod in 1980, now of course Oz could be different...
a spring would work but only if it is light strength. enough to hold the fork back but not enough to compress the fluid back into the master...

i've had that cricket in my BJ74 for three years now, Daryl. Ever since I received it from Japan it's made that noise and hasn't gotten any worse. I spoke with Sheldon about it a couple of years ago, and he recounted a story similar to yours regarding his BJ70. He rebuilt the H55f with a new clutch and new through bearing, and for some reason he couldn't get rid of the cricket. Exact same symptoms...push in the clutch ever so slightly, and the noise goes away.

I had the same problem. I picked up a spring from rona/revy that looked like it was for an old lawn chair. Pretty weak spring but enough to pull back the fork ever so slightly. Used some galvanized cable for hanging pictures and secured one end to the fork and the other to the far side of the slave cylinder.Totally non tech setup but works and has for 2 plus years If you need I will take a picture of it.


Now only if I can get rid of my PTO lever noise. Serenity now!!

LOL!!! Sounds like you and I should go to group therapy together. I've acquired selective deafness to my PTO noise...I barely notice it now.

Cool. Its barnyard but sounds like it works well. I will see if I can rig up something similar. That is, if I can't filter out the noise shortly..Thanks for the confirmations guys.

SO it puzzles me as to why it makes a cricket noise. A brand new bearing doesn't make that noise. I'm thinking that the hub must wobble back and forth ever so slightly on the front tranny cover. The FSM has a step in the clutch section about measuring the runout of the clutch forks, I wonder if making sure they are all within spec would help? Just thinking out loud here.

As far as the PTO gear, I've found that that’s the one noise that actually decreased. In my experience, Cruisers seem to maintain 'balance'. If you make one noise go away, another suddenly appears or if you fix something, the next day something else starts spewing out its innards. Just the law of averages I guess.

If you have a look at the clutch release fork out of any BJ7 or HJ6 you will notice that the the two points where it contacts the bearing are polished like chrome.. I am pretty sure that is it. Things wobble just enough to get those parts rubbing back and forth.
I guess one could put on some brake lubricant or something that won't harm the friction surface of the clutch but who knows how long it would last. Cruisers just have crickets.

Been about 10 years since I've worked on the more mature cruisers so my memory is a little hazy. Just covering my bases.

Burger, you should keep an eye on the free play of that wire. As the clutch wears that wire could hold the fork against the clutch.

It looks like Princess Auto spring #3806262 saves the day again (See https://forum.ih8mud.com/showthread.php?t=64590)

I used this spring and doubled it back around the starter ground wire. Now it sounds like a cricket far far away rather than a field of them under the truck. For a cleaner install, I might try a slightly stiffer spring and not double it back..


Thanks all.
