datsqik Posted August 13, 2005 Share Posted August 13, 2005 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.

Japtastic-UK Posted August 13, 2005 Author Share Posted August 13, 2005 This is the stage I'm at now, which part do mean I have to remove next?

Japtastic-UK Posted August 13, 2005 Author Share Posted August 13, 2005 This part seem to have moved up a bit, is that what needs to come out?

SteveL Posted August 14, 2005 Share Posted August 14, 2005 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 ??

Japtastic-UK Posted August 14, 2005 Author Share Posted August 14, 2005 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! Link to comment https://www.sau.com.au/forums/topic/83976-has-any-one-removed-the-insides-of-their-diff/#findComment-1521981 Share on other sites More sharing options...
Packy Posted October 1, 2005 Share Posted October 1, 2005 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??? Link to comment https://www.sau.com.au/forums/topic/83976-has-any-one-removed-the-insides-of-their-diff/#findComment-1615053 Share on other sites More sharing options...
