Between you and @Daan your dictating how I do my build lol. Seriously you've put thoughts in my head, from studying previous measurements I can fit something in there bloody tight but doable I think. Nothing on the net suitable so going to have to make something from scratch. Inner axle case bore is 69mm and halfshaft diameter at splines is 42 mm, so that gives me 27mm to make a single acting hollow bore pneumatic cylinder, my ARB lockers only have O rings to keep air pressure in so I will also go down that route using the return spring built into the diff to push the piston home when air pressure released. The beauty of this is that the diff lock mechanism will be totally protected by double thickness axle cases Also I could install a back up cable system that could be stored away until needed pending a failure of pneumatic cylinder, thoughts and reactions are compulsory lol regards Stephen Edited December 31, 2021 by Stellaghost 3 Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 31, 2021 Share Posted December 31, 2021 I accept no responsibility - people should know better than to listen to idiots on internet forums! The reason I suggested concentric clutch release is that it doesn't need compressed air - the Volvos use engine vacuum, but a simple cable or passive hydraulic master/slave also appeal for simplicity of operation. Not sure why you'd need to include a backup system, if it fails surely it's not too hard to lock it up by hand somehow if really needed?

True, but I'm thinking if I put a manual system in so I don't have to crawl under a vehicle that could possibly be stuck in mud, having said that I could winch to dryer land Regards Stephen Quote Link to comment Share on other sites More sharing options...

So having listened to said idiot lol a bigger idiot has started to see how doable it actually is, so the pictures below give an idea on the limited packaging space available Inside diff case With halfshaft installed going to have to remove some of that inner casing bulb diff lock mechanism ,cylinder is going to need to move around 30mm diameter of bore to play with 69.7mm Slightly undersized cylinder wall fitted to give an indication this may end up being a lot of work for nothing but as I've said before nothing ventured nothing gained potential problems Fitting some sort of thrust bearing / mechanism to push on diff lock cog face Choosing internal o ring type to withstand air pressure, axial and possibly rotational movement thinking ptfe ?? Feeding cylinder with compressed air once installed, insert air pipe through axle cases?? Fastening cylinder in place so it can be removed for seal replacement, i have ideas on this may get away with an aluminium crush tube arrangement that will nip cylinder in place once portal hubs installed and nipped up Anyone think of anything else or even just say its a load of carp Thoughts appreciated as always regards Stephen Edited January 2, 2022 by Stellaghost Quote Link to comment Share on other sites More sharing options...

That axle casing looks very tight - at least the Volvos are square and have a bit of wiggle room, the mogs seem to have just filled all the available space with more metal just in case Quote Link to comment Share on other sites More sharing options...

Stellaghost Posted January 10, 2022 Author Share Posted January 10, 2022 So my mog axle lightweight project now has a new name, this will keep me straying close to names associated with other Unimog/ Landrover/ Buggy projects on this forum. Name related to some comments here... and because it's built to last....... So from now on it is affectionately being called..............

Stellaghost Posted January 11, 2022 Author Share Posted January 11, 2022 So been having a wee bit of sedate pottering over the last couple of days exploring " idiot" suggestions Started making pneumatic cylinder on lathe slid into position not as far up as I wanted but bore tapers in so I will have to adapt from diff side bench testing rig Halfshaft in More to follow regards Stephen 1 Quote Link to comment Share on other sites More sharing options...

Popular Post Stellaghost Posted January 11, 2022 Author Popular Post Share Posted January 11, 2022 Happy with bench test will be better in axle when no scope for movement Next issue is fitting some sort of thrust bearing so cylinder piston does not spin and wear o rings prematurely Cue one landrover clutch release bearing cut plastic insert out make carrier bush to press into piston and then press clutch release bearing on Fit it together how it will look so all I need to do now is package it into axle...... that will be another story...... regards Stephen 5 Quote Link to comment Share on other sites More sharing options...
miketomcat Posted January 11, 2022 Share Posted January 11, 2022 Those bearings just press off the plastic carrier, no need to cut the plastic. Just saying. Mike Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted January 12, 2022 Author Share Posted January 12, 2022 Think I've got this packaging sussed Managed to trim bulb with plasma cutter because this didn't work next problem cannot quite reach with disc grinder so bodging in order.. one shaft from knackered grinder some heavy wall pipe pressed together Grinder tightening nut welded on sorted then cleaned up with die grinder, burr and flap wheel had to thread air line through axle to achieve this air cylinder piston cut to length Placed into axle tube and air pipe connected I then installed diff, video to follow What's left to do, obviously make another one for rear axle Solder copper pipe in and feed through axle case, just don't know best way yet Roll up an aluminium crush tube to keep cylinder tight in bore Think that's about it regards Stephen 3 Quote Link to comment Share on other sites More sharing options...
