Title: LT95 Center Diff.
Post by: circlework on February 24, 2015, 04:41:02 PM

Hi All,

Wondering if the center diff cross pins in a Perentie are a single unit, or two pieces.   The parts list says two pieces, but a few people have told me it's one piece.
Could someone put me straight please.

Thanks Philthy.   Nice crosshatching, better than expected.
Are the pics of your unit?   If so, how many clicks has it done and how much wear was there?

Pretty sure it is the same cross shafts as the LT230, which means the one piece cross pins from Jacmac are suitable as an upgrade.

No thank goodness the image is one that has chewed itself up ...

Just lifted the image as it answers your question better than words.

Double check your part numbers before you buy at a distance as they maybe the same as a LT230.?

I can confirm that they are the same crosspin in the LT95 and LT230.

Thanks guys.

With all the negative press for this part, I'm inclined to go for a one piece pin from either Jacmac or Ashcroft and steel shims.
Is there a preference between the two?
I currently have the original LT95 out of 49-181 being rebuilt down in Hobart, so I may as well get the diff done properly, as from memory, when the TB oil was drained, it rained brass.
I'm hoping that I'll be doing a lot of sand-hill work this year and upgrading is more of an insurance policy.
And no, the budget won't stretch to a Quaife, although, if I win Tatslotto ....   :)

Good decision Daryl. I can vouch for the Jacmac ones, I have used a few of them without any hassles. As you say, good insurance.

Oooops ... all superfluous now ... box is finished, or at least, the CD is, so I'm too late.
I've been told that the box failed due to .... wait for it ....
a 'missing roller bearing between the two main shaft halves'.   The only thing keeping the whole shebang together was the baulk ring, which eventually wore out.    It took 5000km to fail.   At least, that's the distance done in my care.
What I find amazing, is the fact that through all that torture, there was never any associated noise.   No whining, nada and no record of replacement in the service record book.   I think myself lucky it never 'let go'.

Some pretty sloppy work done by some of the transmission repairers. I saw one that had no rear layshaft bearing cup installed in it. As expected was making some noises. ::)
