Need to know how it is done as I am in the middle of changing mine at the moment but can't get the damn thing out, I have removed everyting including the 4 bolts you see in this picture, can any one give me a clue of how to get the main unit out?

If you have removed the 4 bolts then you need to pull the bearing caps out.You may need to give them a tap with a copper/plastic hammer and mark which side they came from.The centre can now be removed,sometimes these can be pull out by hand or you may have to use a long screw driver to lever it up on each side if it is tight.Remember these have shims on either side and need to go back in the same way and so do the bearings unless you replacing the bearings or the centre or adjusting the tooth mesh/backlash.

It should pull straight out of the housing with the caps removed. Sometimes the shims can be tight and that makes things a bit more difficult, but in those cases tapping on the side of the crownwheel (ie opposite side to teeth face) with a rubber or plastic mallet will usually free it up. The parts you mention that are loose are the spacers and shims for setting up CWP relationship.

Datsqik is on the money - make sure you mark everything and keep it all in the same relationship for re-assembly. If your changing the centre and/or the CWP the shims will almost certainly need changing, but it's rare for the bearings to give trouble (mind you, if it were me and I was changing the centre and CWP for something new, I'd have a tendency to change the bearings - esp if this was for a high HP app).

I'm probably seeing things, but that's not sealant I'm seeing around the bearing bolt holes, is it ??

No sealant where it shouldn't be.

I'm swaping an manual diff for an auto one, found one cheap and it will be good for the drag strip becuase the ratios are different, the casing is only 1cm longer so hopefully this won't cause a problem, the prop shaft moves loads any way.

Can't shift either of the guts from either unit out though.

The new auto diff didn't come with the driveshaft flanges so I was in the process of just swapping them over but they are either different or the sir clip was bent as when one went in it got stuck and won't go fully in and now it won't come out whatever I do, so I think the only option is to take it to the local transmissions shop to see if they can shift the bugger!

What a nightmare!

hmmm good someone else is doing this diff opening too.

I've got a 2way Kaaz waiting to go in. I'm a step before though, i still have the half shafts in the diff, how do you remove them???? I've got the bearing caps out, just can't figure out how to get the shafts out of the centre itself??? Any help guys???

    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
    • You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.
    • The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:
