  1. There is also the problem that affects all rover diffs, and that is the crown wheel deflecting under high loads.

    Diff pegging solves that.

    the solution was to grind a narrow spiral in the shaft to increase oil flow between the gears and the carrier shaft

    That looks simple and effective, and does not need any extra parts. I like it!

  2. More vapour build!

    It is said that 99% of Rover diff failures are caused by pin failure. That is caused by the diff spinning and melting the planet gears to the pin. With two planet gears melted to the pin and the diff trying to spin...bang! Bye, bye pin!

    Planet gears and pin could be moddified in the lathe and some bearings added (similar to those used in chainsaw engine crankshafts).

    Feasible or too crazy idea?

  3. Does Mikeno really exists? In late 60s Rover/Land Rover created the brand "VELAR" and badged with this brand the first Range Rovers protos. That way the motor press never knew nothing about the new Land Rover until it was launched. Is the Mikeno the new Defender in disguise?

  4. Truck engine in a series!, what next?

    Amphibious body? :rofl:

    what box / transfer case??

    Getrag GFT MT82 (Ford Mustang, Transit, Ranger, LR Defender '07 onwards, rated to something above 500Nm). LT230.

    Rover axles with Ashcroft treatment.

    How much does it weigh

    No idea. Shouldn´t be much more than a Santana 3.5 six

    - How much torque does it put out?

    - How many cylinders is it?

    417Nm@1300rpm, 137HP@2600rpm, four pot.

    What would you do about gearing?

    The 109 is taxed as goods vehicle, so anything above 55mph will be illegal. For that speed there is no need for high gearing or high revving engine. Engine revs up to 3000rpm

    There's also the question of space & cooling, have you measured the engine, and how much radiator does the truck have?

    70cm wide, 80cm long (add 15cm for flywheel cover), 70cm high up to the top of the intake pipe, add 15 cm for sump.

    x6md.jpgI forgot measuring the rads

    why not put in a 2286 petrol? Or a 2495 petrol?

    No thanks. I love diesels. Will be used daily (80 km).

    rd28 was favourite in land rovers

    Plenty of them here, as it was used in locally built MQ160s. Will prefer a LR Tdi instead of one of those.

    not consider overpowering a Series LandRover in the first place. Not without changing the whole drivetrain anyway

    This engine swap will need to be part of a whole vehicle upgrade

  5. The 2.25 diesel of the 109 is certainly underpowered. I have allways thought about the 200Tdi, but if I´m going to swap both the original engine and box, why not something bigger?

    ISUZU 4BD1T is a great engine, fitted from factory in aussie perenties, but impossible to locate here in Spain.

    EBRO, a spanish light/medium truck builder, was bought by NISSAN in the 80´s, so their extreamly popular range started to use spanish built japanesse engines.

    At work we have two EBROs, both with the NISSAN B4.40 engine. The 5 ton one is N/A, 90hp. No power, but still going strong with nearly half a million miles on the clock. The 8 Ton unit has the "Eco system" (Turbo + intercooler). 135HP. This is the one I usually drive. It´s a real pleasure. Feels more powerfull than the 180HP Renault we also use (if you are not carefull with your right foot you can end with speeding tickets!), no breakdowns (half a million kilometres on the clock), low fuel consumption (lorry is 3m high, 2.3m wide, 15/16 L/100km), axhaust valve for engine breaking, built in air compressor, easy to locate both engine and spares, well known by local whorkshops...but here is the big question: what about the rest of the world? EBRO lorries were sold only in Spain and Portugal. Whas this engine marketed in Europe and Africa? Any known transplant on Landies?

  6. This is another aproach...tridem!

    .ajp9.png

    Axles 2 and 4 will be lifted 95% of the time. If the terrain is soft, all three axles will give extra flotation. Need a super reduced turning circle? Lower axle 2 and lift axles 3 and 4.

    Making the tridem compact could be possible using narrowed series axles for 2 and 3 and a widened coiler axle. Could be easy with the correct offset reversible wheels, just in the same way as seen in front vs rear axle in twin wheeled vans.

    That will give an axle arrangement similar to Nazi tanks.

    .panzer-tank-blog480.jpg

    Problem? If you need to take out one wheel from axles 2 or 4, you will need first to take out axle 3´s wheel.

    Packing transmissions for 3 axles in so little space is another challenge...

  7. .Series diffs have a bolt on pinion seal housing fasted by 6 5/16'' bolts I drilled and retapped the bolt holes out to 3/8" to bolt the dropbox on but there is an additional brace welded to the diff casting that bolts to the drop box for extra support.

    Unfortunatelly I have no access to one of those. Even our SI LWB hearse has Series III style diffs, with no six bolt seal housing
