Hybrid_From_Hell Posted March 3, 2011 Share Posted March 3, 2011 http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/tongue.gif Righty Ho then - This is the Tools n Fab forum after all http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/biggrin.gif Doing more pegged diffs than ever means Steve having to remove old knackered good and bl**dy defo "On" Bearings on Diiferential Pinions. They are a piggy to get off, and there is a special tool available, we had one at KAM and it was a wobbly bendy thing that barely did the job, considering how much is was it was a joke. I was given the 2 x shells for the unit (which can be bought) and decided a HFH HD version was in order http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/smile.gif Its was this one : http://shop.dingocroft.co.uk/acatalog/Other_tools.html @ £618 FFS http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/laugh.gif So, I had a rummage around, and that Nice Man Rogue Vogue had a lumpy bit of round 30mm thick plate and I had some 30mm flat plate (as you do) coupled with some 30mm Rod and a lump of M36 threaded bar So, after an age of machining on the lathe I had a taper on the base plate, and then tack welded the falt plate to it and machined so all linned up, and poked a very large hole through the plate to allow the M36 2 x Nuts tigged together (will give stronger hold of the push bar than a single nut), and 4 holes drilled right through the entire assembly I ended up with this : Once I had done this the welds were broken and the assembly slung together to allow tack welds to go in place when all square : I then decided to have some much needed TIG practise, and used up all the left over short ends on the floor http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/rofl.gif Some considerable time later I had this : Then grabbed a knackered pinion with a "Well on" Bearing on it, and gave it a whirl - It works ! Cost ? Erm "S*d All " Really http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/smile.gif If anyone needs to pinion bearings removed give me a shout, its heavy enough not to go anywhere far http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/laugh.gif and big enough not to loose http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/smile.gif Worth looking at Making these "Special Tools" now and again vs paying for them, bit of thought and time and bits can even see a better unit than what is sometimes sold, may end up getting the threaded bar Heat Treated to give the tip a longer life, but "Suprisingly" Nothing flexed - at all http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/smile.gif Other thing I have often thought of would be a Drop arm puller for a 4 Bolt Box http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/smile.gif As and when I have the time maybe, but this is one "Needed tool" off the list http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/biggrin.gif £473 + Vat http://forums.lr4x4.com/public/style_emoticons/#EMO_DIR#/rofl.gif I am not a pro, have an old lathe an trully acient 50's milling machine, with basic tools, time and a bit thought you can make this sort of thing and save a fortune Nige Quote Link to comment Share on other sites More sharing options...
landroversforever Posted March 3, 2011 Share Posted March 3, 2011 Looks great Nige . Will it work to press them back on too? Quote Link to comment Share on other sites More sharing options...
dirtydiesel Posted March 3, 2011 Share Posted March 3, 2011 Daft question, but why not just use a hydraulic press? maybe make a bolt together press tool to go around the pinion under the bearing. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted March 4, 2011 Author Share Posted March 4, 2011 Not daft at all DD 1. Erm - I don't have a Hydraulic Press 2. Tried another method with 2 leged puller - rips cage off 3. Hence copied the "Special Bargain Value Toopl" 4. I have the bits of plate / time to make it 5. F Big enough I hopefully won't lose it in the s**tholemess workshop Nige Mmmm Hydro Press, Mmmm Likey - now where could I squeeze that in to whats beginning to look like Mr Treabus Workshop Quote Link to comment Share on other sites More sharing options...
simonr Posted March 4, 2011 Share Posted March 4, 2011 Well done Nigel - that looks very proper! Over the years I've made several 'special tools' and even though, in general I've only used them once, I'm still quite proud of them and am keeping them safe for the next time!

LandyManLuke Posted March 4, 2011 Share Posted March 4, 2011 in general I've only used them once Often, once is enough! There are situations where the time taken to make the tool has been completely warranted by the task. The bonus is, even if you don't plan on using it again, if the occassion arises, the tool is ready and waiting, and free! Quote Link to comment Share on other sites More sharing options...
dirtyninety Posted March 4, 2011 Share Posted March 4, 2011 Ive made several special tools and I always put them in that "important place where I wont forget where it is" Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted March 4, 2011 Author Share Posted March 4, 2011 Steve (ex KAM) and I used it today "With a Vengence" One pinion bearing was properly on there - we had the unit clamped in the vice and he was "Giving it large" on an !2 Drive Breaker bar with the socket on the threaded bar, the bearing actually broke partly a shoy out a lump of the inner race which missed us both , and after we had both gone "Oooer F" he pulled some more and bearing gave in and came off All in all Chuffed, however he did "Comment" as to the not insignificant weight when staggering about with it Nige Quote Link to comment Share on other sites More sharing options...
bishbosh Posted March 6, 2011 Share Posted March 6, 2011 As far as heat treating the end goes, why not drill and tap a block of steel to use as a sacrificial tip? Quote Link to comment Share on other sites More sharing options...
