Fitted Calmini 5.14 gears recently and was disappointed with the whining noise and rattling in higher gears. took case out again to fit Twisted T shifter and when I refilled it I used 25% Moreys oil stabilizer and like magic all the noise is gone. So happy
Love that Moreys

So you used an oil stabiliser to mask a fitment issue? Not sure how thats going to work out for you long term.

You should expect a slight increase in gear whine, but rattling?

[abclarke]

Haha reminds me of that brake pad noise spray stuff. I never really liked the idea of masking a noise, basically the same as closing your eyes and fingers in your ears. If you dont know its there it cant hurt

[Built4thrashing]

lalalalalalalalala what noise lalalala

[Teracis]

The whine I can understand but rattle seems dodgy dude!

Maybe when you pulled it apart and put it back together again you got it right and the rattle left eh, just tell yourself that or something

Rattling sounds like the gear on the middle counter shaft floating around.

Shouldn't the shims stop that? But yes, I can't think of anything else that wouldn't have been ridiculously noticeable before he put it back in the truck.

They should yeah. May have been left out?

I have seen a shim(thrust washer) come out with an oil change.. It stunned me at the time but a few weeks later I fitted gears to a case and had the shim(thrust washer) fall out of place as I was installing the shaft. I noticed it had moved and fixed it up but others haven't in the past.

I put a smear of grease on the back of the thrust washers when building the case. It helps keep them located until the counter shaft is in place.

Me too! Fuckin' drives me crazy when they jump off.

[want33s]

Yeah I use a dob of grease too but it doesn't always work first go.

When gears first fitted they whined and up in higher gears 4th and 5th sounded a bit rattly on over run though this did seem to settle down. I have used Moreys in a 10 speed roadranger box in my bus/motorhome and have been happy with the noise reduction in that.
Everybody has complained about the noise of the Calmini gears so I have just offered an option to quieten them down.
Take it or leave it, but it does work.

I wasn't disputing the use of the moreys.

I was debating the need for it in a t-case with correctly installed gears.

All reduction gears will whine. So the moreys is a good solution AFAIK. But the rattling is NOT normal. You should address that.

[Macca52]

I suspect that the shim may have been put in the wrong way around the first time (not sure if that is possible because of the locator) but there has been no sign of the rattle this time and I spent a fair bit of time in low 5th yesterday in the mud at Toolangi so I am not too concerned about it.

[c1ockwork]

Just further to Macca's comments, I gave the Moreys a try in my Coily with 5.14s and it does indeed quieten down the gear noise significantly. The whine with the 5.14s, whilst liveable, is certainly not pleasant. After loads of internet searching I didn't find anyone with anything bad to say about the product, and having seen its consistency (it's like honey) I can see why it might quieten things down... I know, I know - it's a Zook, but the quieter it can be made the better! Thanks Macca.

There's also a noise that's only present in 4th and 5th low range which appears as soon as the gears are engaged and stutters on over-run, but I wouldn't refer to it as a rattle - it's almost a cavitational type noise. I didn't rebuild the transfer case (my brilliant mechanical skills preclude me from doing so) but I'm now wondering if I am suffering from the lost shim mentioned above? Is anyone else experiencing the noise that I'm failing to properly illustrate? It doesn't seem to cause any other issues....

Believe it or not, the selector dogs can actually chatter a little bit from time to time. Given its only happening in the higher gears, and only in low range, I'd say thats what it is.

And you can't 'lose' a shim. The locating tang can snap off, and the shim will spin with the idler gears and bearings on the counter shaft. It does take quite a while, but eventually it will wear the shim down, the idler gears will have room to float, and slight misalignment of the idler gear will occur under load. This places uneven forces on the needle roller bearings beneath, causeing heavy wear of the case hardening on the counter shaft. Once this is damaged, you will know, because the case will get a very definate bearig noise. ( unless your super Moreys masks the noise, in which case the wear will continue untill the gears spit their teeth off)

This is what it looks like.

Countershaft


Idler gear ( runs on counter shaft)


Other gears that don't like munching on missing idler gear teeth.....

[c1ockwork]

Fatzook - thanks for the detailed answer. That's put my mind at ease. Describing sounds is difficult at the best of times but as mentioned 'rattle' would definitely not be it, so I’m glad the likely cause is discernible based on when it happens. I'll be listening for changes nevertheless....

hey guys, i just got my WT case fitted into my Jim and im getting a rattle noise when i put my foot on the clutch and just let the car cruise along, it seems like slop in the gear or something, would these shims that everyone speak of be a likely cause?
