Perentie 6x6 LT95 Gear box

[PerentieNZ]

Hi Guys,

Can anybody tell me if part number FRC9392 with is the High Gear from the transfer box will fit the Perentie LT95 6x6 gearbox?

Best place to source this part? Would you recommend sticking with LR part or after market.

Need to get one asap as the truck is up on hoist.

Cheers

That is the correct part number for the hi range gear on the intermediate shaft. The gear it mates with on the centre diff is FRC4032. You will be lucky to find an aftermarket one. Genuine LR ones will cost you around $1K.

Hi,

The high gear from the Perentie has roller bearings and a machined space for bearing and the ordinary LT95 gear has needle bearings and different centre shape/size.

So the ordinary LR part will not fit in Perentie box unless you go back to needle bearings, correct?

Just want to make sure I get the right part?

That part number is the correct one for the TRB shaft on the perentie. And no the standard one will NOT fit in the perentie even if you change the bearings. You would have to change the complete intermediate shaft and you don't want to go that way!!

Hi Bearman, I now have the gears needed, thanks for your help! Do you know the torque settings for the intermediate shaft bolt? Cheers

125 - 140 ft/lb is the figure for the intermediate shaft bolt. If you have added new bearings and gears you had better check the preload on the gears in a vice before putting it in the vehicle. The original shim may not be correct now.

Hi Guys,

I have torqued the shaft bolt up to 125 Ft/lb with the largest shim 4.6mm FTC397 and it appears i need to space it out more. Have just replaced output and high gears.

The shims start at 3.5mm so i can not double up on a smaller shim, whats the trick here, can you take a very thin shim (which one, make, part number) and put the two together??

I have a feeling this all started from the shaft bolt not being torqued to correct spec originally as it was jumping out of high!!!

FTC399 which is 4.8mm is the biggest shim available and I have found from experience that you usually need this one to obtain the correct preload. I have never used one less than 4.5mm. You can use your current shim to make another small one out of shim material (.2mm)instead of buying the larger one. Unfortunately you can't use 2 of the smallest shims (3.5mm) I haven't done one yet that needed 7.0 mm. Make sure you have seated the bearing races fully in the gears you have replaced. How worn was the plug the bolt threads into that fits into the front of the transfer case? A loose bolt will allow the bearings to rotate and wear grooves into the plug and it then requires a bigger shim, machining to remove the grooves or replacing if it is worn too much. The correct preload is when you can easily rotate all of the gears by hand when you have the bolt fully torqued. Another way to fix it if you don't have access to shim material is to remove a bearing race from the centre input gear and machine or sand it down on a belt sander or lathe.

Thanks Bearman, get it back on the rd tonight[emoji1303]

[Bearman]

Did you get it all sorted?

[PerentieNZ]

Yes thanks mate, must of been wrong since build as I saw you mention in another post that you had found the shaft bolt not at correct torque on a few boxes. Well my box had the biggest shim. So I would say that there were a lot of boxes but together with the thickest shim and then torqued as tight as the gears would allow instead of getting new shims made up. Runs a dream now, would pay for everyone to take top cover off and tighten shaft bolt if it's below spec as everything would of worn a little since new build and maybe causing it to jump out of high range, mine would push out every time in reverse. Runs like new now.

On a side note are the Cab sills on the Perentie 6x6 able to be replaced from another Land Rover model, mine were missing from the start? Cheers

Good to hear it's all working good now. Which are the sills you mean, the ones under the doors?

[PerentieNZ]

Yes, was trying to find some secondhand ones or new from a non military version that would fit, are they Series or defender sills on the Perentie?

Neither, I haven't seen them on any other vehicle. Must have been sourced locally I reckon.
