smo Posted August 10, 2007 Share Posted August 10, 2007 I'm planning on fitting my Jak Mac diffs this weekend - what sealant do i need to use when fitting the casing back on, and do i need to bother with the LR paper gasket??? Quote Link to comment Share on other sites More sharing options...
rick Posted August 10, 2007 Share Posted August 10, 2007 my personal preference is for one of Loctite's excellent flange sealants, 518 for rigid assemblies, (used on my Rock Crusher diff cover and stub axles) or their RTV Silicon type Blue Max if the surface isn't true Quote Link to comment Share on other sites More sharing options...
Troddenmasses Posted August 10, 2007 Share Posted August 10, 2007 My personal preference is for a tube of B&Q's finest silicone sealant. Don't bother with the paper gasket, just clean the sealing faces with a knife, then apply a nice thick bead to the casing. Of all the parts of my landy that leak oil, around the diff has never been one of them. Quote Link to comment Share on other sites More sharing options...
smo Posted August 10, 2007 Author Share Posted August 10, 2007 Thanks guys - to save me going back outside again does anyone know what size the nuts are as i ought to put new ones on Quote Link to comment Share on other sites More sharing options...
Guest WALFY Posted August 10, 2007 Share Posted August 10, 2007 Are they not the same as propshaft nuts Quote Link to comment Share on other sites More sharing options...
Troddenmasses Posted August 10, 2007 Share Posted August 10, 2007 as i ought to put new ones on Ok, If you are thinking about putting new nuts on, even though you haven't had to cut the old ones off, we are obviously talking a different language about Land Rovers. In that case, you had probably get one of those nice Land Rover paper gaskets, and smear it with proper jointing compound. Quote Link to comment Share on other sites More sharing options...

LOL - not really but i dont see the point in using old carp on somthing so important when new nuts are pence each! Quote Link to comment Share on other sites More sharing options...
Mark90 Posted August 10, 2007 Share Posted August 10, 2007 Yep same as propshaft nuts, 3/8" UNF. I use a gasket smeared with grease if faces are true and don't leak, if trying to stop a leak I'd use RTV instead of grease on the gasket.

Guest WALFY Posted August 10, 2007 Share Posted August 10, 2007 B&Q's best silicon sealant for me :D Quote Link to comment Share on other sites More sharing options...
white90 Posted August 10, 2007 Share Posted August 10, 2007 RTV for me never leaked on any I've done and it is the correct stuff Quote Link to comment Share on other sites More sharing options...
B reg 90 Posted August 10, 2007 Share Posted August 10, 2007 If you greese the gasket you can manage to remove the diff in the field and reuse the paper gasket as it will not have stuck. Added bonus is not scraping silicone/RTV off the diff and axle faces. I'd use paper any time. Adrian Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted August 11, 2007 Share Posted August 11, 2007 I've always used the paper gaskets with no leaks so far. Mo Quote Link to comment Share on other sites More sharing options...
mmgemini Posted August 11, 2007 Share Posted August 11, 2007 You should have a paper gasket. That's what the gasket is for. To seal the joint. You don't need anything else. I use a smear of grease to hold the gasket in place. mike Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted August 11, 2007 Share Posted August 11, 2007 Grease and gasket for me if you have them (they're only pence and come apart much more easily), RTV if not. B&Q now do aerosol sillo - very handy thing to have in the truck for all your roadside repairs. Quote Link to comment Share on other sites More sharing options...
Troddenmasses Posted August 11, 2007 Share Posted August 11, 2007 Grease and gasket for me What utter, utter rubbish - you are the one who taught me to use silo, and are the only person I know who bodges things more than me. For about 3 years, instead of buying 4 self tapping screws to hold your Landy stereo in, you used a bit of stick - wedged between the bottom of the stereo and the seat box...

Turbocharger Posted August 11, 2007 Share Posted August 11, 2007 Re-read my post. I never said I'd actually owned a diff gasket, just that I would use one if I did. Besides, the stick has now passed into legend and has Grade II listed status - it is preserved behind the passenger seat and will one day enter my collection in a museum.

will_warne Posted August 12, 2007 Share Posted August 12, 2007 I've used both RTV and the propper paper gaskets. RTV never leaks even if you're sloppy preparing the surfaces. Gaskets work as long as you grease and ensure the surfaces are clean. As Adrian said, the latter allows for easier removal / field repairs and that's how my diffs are at the moment. Oh, and slightly OT. A chap I know was pulling a diff yesterday, slipped, tried to catch the diff and caught the mouting face (which was sharp) and ended up with an inch long cut at the base of his thumb that was down to the bone. On that note, enjoy Sunday Lunch Quote Link to comment Share on other sites More sharing options...
CosZuki Posted August 12, 2007 Share Posted August 12, 2007 why would you be repairing the diff in the field anyway? surely they dont break that often? Quote Link to comment Share on other sites More sharing options...
