Disco-Ron Posted April 13, 2011 Share Posted April 13, 2011 Ben, you say you'r enow only getting one and a half clicks on the transfer box arm, have you tried doing it with one of the wheels in the air, so you can jiggle the wheel whilst trying to select either low or high range etc, as it may not be engaging, hence the lever not moving as far as it should.............

benthegardener Posted April 15, 2011 Author Share Posted April 15, 2011 Right finally back at a time when I could have a look. Stripped off the gearbox covers and found the transfer box linkages are ok, well apart from the missing pivotting clevis on the difflock linkage but i knew about that and stuck a bolt through for now while testing in the yard. So did the gears in high and did the gears in low nothing but whirring. no drive Difflock on and difflock off, did the gears and nothing but whirring again. no drive Jacked up each wheel individually and tested each one difflock on and off. Each turned the propshaft and the difflock engaged properly and locked the wheels out. I noticed two things When doing the front wheels the front diff is very noisy, bit like a rumbling wheel bearing noise. And much noisier than the rear. Also the difflock lever, (by which I mean the actual bit on top of the transfer box) is definitely not going as far over into the off position as it did. Is this indicative that something has jammed up inside? I guess the next step is to drain the transfer box and the gearbox and see what comes out? Anyone getting any ideas yet? I really want to get my truck back on the road asap, I really miss it, and the TD5 I have on hire seems to be doing lower mpg too. Quote Link to comment Share on other sites More sharing options...
benthegardener Posted April 15, 2011 Author Share Posted April 15, 2011 Mainshaft worn out. I am convinced after looking in the tech archive and finding this http://forums.lr4x4.com/index.php?showtopic=6840 Make a start tomorrow then!

JJB Serenity Posted April 17, 2011 Share Posted April 17, 2011 I know we all hear about the mortal perils of driving about with the diff locked on tarmac, but has anyone actually broken something as a direct result of having the centre diff locked Not broken anything but this isn't a good look: Quote Link to comment Share on other sites More sharing options...
benthegardener Posted April 17, 2011 Author Share Posted April 17, 2011 Just for a bit of closure on this. Have taken out the gearbox and transfer box etc. Gearbox mainshaft as smooth as you like. But also a good collection of water in the transfer box. Been an absolute swine with floor bolts etc, Took the opportunity and replaced the rear main seal behind the flywheel, new 130 clutch fitted up. Hopefully new box in over the next couple of evenings. Fun and Games! Quote Link to comment Share on other sites More sharing options...
poohbear Posted April 18, 2011 Share Posted April 18, 2011 Glad to hear you found the root problem! Just out of interest - any tips for removing trans as I have an lt230 to fit and suspected weeping crank oil seal to investigate. Happy fixing! Dave.

FridgeFreezer Posted April 18, 2011 Share Posted April 18, 2011 I've always found it easier to drop gearboxes out from underneath than take the floor up. Bit late now of course... Quote Link to comment Share on other sites More sharing options...
benthegardener Posted May 1, 2011 Author Share Posted May 1, 2011 May have been better going down than up, but the tech thing above is useful. I'm having a right old fight getting the box back in this evening. Goes so far, I can get 2 nuts started on the studs at the top but then wont go in at the bottom, any ideas? Have I put the clutch in backwards or something, or just being a bit gentle? Quote Link to comment Share on other sites More sharing options...
poohbear Posted May 2, 2011 Share Posted May 2, 2011 Have only mated engine to box before - rather than moving boxes around, but I found centering clutch friction plate is crucial. Also found judicial use of brute force helped! D. Quote Link to comment Share on other sites More sharing options...
