As primised the upgraded diff kit arrived today. Yahoooo...Now I know I should not get excited about this but im in the north of scotland and next day delivery is rare..



And so to the garage I go.........Right then I started by plonking the new fibre washers over the pinion gear shaft things. gonna call them "Bob" because I have no idea what the real name is.



Note I have fitted the spring clips as instructed. Next I put "Bob" in his cage.



Then I placed the new copper looking washer thing in the cage and then the new planet gear on top. Is this the planet gear or is it "Bob"?





Next up was to slide the new diff pin in and place the center bit that seperates the two Planet gears on the pin as it slides through. Make sure you are keeping the slot in the end of the diff pin in possition for the roll pin to fit. Also note the possition of the middle bit. The fork bits that stick out should face "bob"



Then the last planet gear and copper looking washer go on the other end and the diff pin can be pushed all the way in.



At this stage you will realise why it was important to keep the slot in the diff pinn lined up because if you cant see through this hole you wont be able to put the roll pin in.





Make sure it sits flush or even slightly inside the hole. Now I put the other "Bob" into the crown wheel.



And bolted the crown wheel back onto the cage. Dont forget the bits that go behind the bolts.



Then I torqued them up to 56 ntm and knocked over the tabs. I dont know the correct torque for these bolts so I just guessed at 56 being enough.



The Diff bearings went on next with the help of my deep ball joint socket and the hammer.



And there you have it, 1 rebuilt and upgraded diff.

I have placed it on the gear box for a nice picture, and then put the diff housing over to keep the dirt off for now.





Yes I did paint the diff housing!!! I know Im a sad old git!!!

Next will be the gaskets and time to get the shims sorted, I kept the old ones nice and safe so I am just going to bung them back in and try it. But I have a sellection of shims from two other boxes so im fairly confident I can get it sorted.

See ya!
