Front LOKKA Install on a four pinion type diff centre - L300.
Here is my installation of a Lokka Lock diff kit to my 93 Model L300(P24V). I can only add 10 photos at a time so i will have to upload then add below the rest. Sorry about this
So the official Lokka distributors are through 4WD Systems in South Australia. The Kit/Part number has been changed to "LK-77". These are a brand new kit and this is one of the first installed into the four pinion style centres on an L300. There were a few teething problems which i'll get into as i go.
When it comes to dealing and ordering with "4wd Systems", do not waste your time with the website or with emails. Just call them (Australia: +61 08 8362 5955). I sent them an email and after two weeks with no response, i called them. When i spoke to them, they told me they are the busiest they have ever been in there history and they have stopped responding to emails as there is over 5000 emails in the inbox and growing daily. So just call them. Once i called and ordered, it was sent the next day.
I wont bother with any info or photos on the actual removal of the diff centre as it is the exact same process as with the two pinion style diffs. There is plenty of info already in this forum so ill skip straight to the kit install. The most important things to remember is to keep the side gear shims, bearing caps and bearing shims in there correct pairing. Left with left, right with right. Bag and clearly mark these. DO NOT MIX UP THESE PARTS. These parts are crucial with the correct assemble of the centre back into the housing.
Here is the link for the removal of the complete diff.

So Lets Get Started
Here is whats comes in the kit "LK-77". One more spacer is included but not in the photo.
NOTE- If you read the install post on the 2-pinion type centre, you will read about the spacers needing to be machined for proper fitment. A small chamfer needed to be machined onto the inside of the spacers. This problem has been addressed with these kits, so this is not needed. Although i still did some cleaning up of the edges as i felt the machine work could be a little better. some of the edges were a bit sharp and rough.
-After following the removal procedure you arrive with the complete centre out of the housing and ready for the kit to be installed. This is where you must mark the crown wheel gear to the centre housing. This is so you can put the crown wheel back on in the exact position as it was before. IMPORTANT.
-Diff centre with crown wheel removed
-The main difference between the 2-pinion and 4-pinion type centres are the housing. The 2-pinion centre is a one piece housing while the 4-pinion type is a two piece housing with a top and a base. With a punch i marked the two halves so i could assemble them same.
-Remove the screws that were under the crown wheel. These are the screws holding the two halves together.
-The two halves come apart giving access to the planetary gears.
-Another view of the lower half of the housing with gears inside.
-Flip upside down the housing and push out the locating pins from the housing. There are 3 in total and will more than likely just fall out themselves. On the 2-pinion type centre, these pins are punched in hard, while on the 4-pinion type, they just side in there and the top plate bolts down over the top off them so they can not fall out. This makes them super easy to removal and install compared to the 2-pinion type.
-Here you can see the locating pin and how the come out
-Now the locating pins are out, you can pull/slide out the larger drive pins.
Note; This is all i could post in one go. More to follow......
