The Landrover Cummins (12v 6BT) Conversion

[darrenjlobb]

Bit more progress, finished bolting up the trans mounts, and got handbrake setup all back on / working. Then went about mounting the controls for diff lock / hi and low on the transfer box, OEM done via a second gearstick, but decided given the total re location / size of the new box, it was going to be more hassle than its worth to mount that, along with the fact that I hate the standard all in one lever anyway. Thought about mounting them on air rams with switchs, but tbh, at the end of the day , you can beat a good positive CLUNK, so you know its in.!

So have made up two levers, one operates low / high box, and the other engages / dissengages the diff lock. once finished / we have made up a new tunnel cover, will chop them down / weld gearstick bar on the end and put some knobs on them, but both work perfectly, and about 20 X more positive than the OEM system!






Then decided it was time to seal up the rest of the holes on the engine, the lorry had a big long remote oil filler neck on it, so salvaged the flange from it that fits the block, chopped it in a few places / welded it to form a new tube that runs up the side of the engine, and oil filler cap at the top, meaning engine is now "ready for oil". Didnt take photos of that..

Next big job was to sort out the clutch, In the lorry it runs an air assisted clutch (to make it lighter), so considering we have kept the onboard air compressor, decided it would be win to keep this, as super light clutch pedal is ftw, and everyone knows a "Psssttt" from the clutch every time you depress the pedal is full of win!!

So firstly rigged it all up with 100psi feed from air compressor, and few temporary fittings / lines to hook up the hydraulic side:



After deciding the plan would work, I set about mounting a new master cylinder, the landrover one has far to short a stroke, and also a very pissy bore, which wouldnt move near enough fluid to operate this thing, and we had a OEM leyland unit, so decided this needed to be mounted, which obviously was about double the size of a stock one... So chopped up the stock housing, and welded up my own supports etc to hold the leyland unit, but still retains OEM un bolt / replace ability ..



All in and bled up, and working a charm, just need a remote reservoir to hook up now and it will be sorted!

Next is plumbing up the onboard air, and power steering..which requires regulator as the onboard pump is far to chronic for landy steering box!

P.s. for anyone who hasnt already noticed, this is being built fairly "on a budget" hence alot of the steel being used here is literally offcuts...Its not pretty, but its a landrover, and its a good way to use up all that old steel you have lying around in the corner of the workshop! Shows you can do alot with scrap tbh, only main expenses so far is the engine (500 quid removed / complete from local scrapyard) and a few fittings / bolts etc...And obviously grinder discs / welding wire and gas, but overall, entire projects owes easily sub 1k
