some one solve this for me.......... buggy question

Post by NICK »

You take a navara transfer case which has a left hand drop and fit it to a moon buggy with a commodore v6 and auto, 60's landcruiser diffs. easy


do you need to flip the diffs?


second question, if you were to use a 350, 2 speedglide and GQ transfer and make the motor run backward would you need to flip the diffs?


Yes i have way to much time on my hands.

Front, I would say yes. Rear, I don't know.

No. But I don't know if the speedglide & transfer would like to run backwards.

how could you flip one and not the other, this would drive the 2 diffs toward each other.

as for the glide and transfer. the transfer would be no different to driving a normal truck in reverse for a period of time, however i cant get my head around the auto drawing the fluid through the pump ruther than pumping it. i think it would close the valve body off and cause the converter to flair.

You need to flip diffs in both situations.

Now that you have too much time on your hands...

Pen and paper or work this out in your head.

draw pic of diffs and their direction being forward

draw pic of motor to t/case in standard position... now turn it around...

diff direction is now backwards because the transfer case is now rotating in the wrong direction giving a reverse drive to the diffs... flipping the diffs around reverses the drive back again to forward.

Hope that helps..

The first one yes you will still need to flip the diffs. And move the pumpkin over on the front to suit the LH drop.

The second one if we are still talking a moon buggy then no you would not need to flip the diffs as long as it was also possible to get the auto to run backwards. Ive never seen that done though. The motor is a simple mod to run it backwards though as its done in a lot of inboard boats.

if you turn the gearbox around the out put is now on the RH side matching the 60s diffs before flipping them, this is how i got confussed with the rotation of the drive shafts or the flippin of the diffs.

Correct but you would then have 4 reverse gears and one forward if you dont flip the diffs ;)

In theory maybe.. but in practise its almost impossible.
The engine would need custom oil pump, water pump, camshaft and distributor. The powerglide is another drama. The pump won't work if spun backwards, neither will the torque converter.
If you did somehow manage to get it going backwards the transfer wouldn't like it much as the bearings and shafts are set up to take the load (primarily) in one direction only.

mount motor and gearbox backwards ???

water pump at back and transfer at front ??

as above - getting a auto or petrol motor to run backwards is NOT easy...

The Evolution Warthog that was a TTC07 Alternate this year ran the motor in the back, into a powerglide, then a marine V-drive to send drive forward to a Stak 3 speed transfer.

Its a simple marinising kit. As i said its common in boats. Very common.

Sorry for the hijack but, why is it common in boats?
Something about countering the torque in twin engine setups or something?

Marinising makes the engine run backassed how? :roll:

Left and right hand rotation chev's are common in boats, PCM mercruiser etc, mainly for twin enigine setups

Camshaft,oil pump,distributor,water pump and starter motor. I prob shouldnt have called it a marinising kit either as that is the common term for a way of cooling an inboard engine as most use sea water to cool rather than a radiator. Commonly they suck the water in and blow it back out the exhausts. I prob should have called it a counter rotation kit. Which as someone said above is used a lot in twin inboard engine applications.

Never seen a counter clockwise ENGINE kit as suggested. ONLY ever seen reverse rotation legs.

Not just Mercury(Mercruiser) but most manufacturers make a reverse rotation leg for twin engine setups ..EG: Shark cats

"Due to the higher production costs and the advent of fuel injected gasoline engines bristling with computer modules and sensors, engine manufacturers discontinued reverse rotation engines in most cases. Since then, engine outputs have been handled by reduction gears capable of reversing engine output rotation. Both engines are standard left hand rotation but the reverse reduction gear changes the starboard engine output to right hand rotation. This is a much simpler, less expensive way to handle the need for opposite rotating engines. "

That would explain why I've never come across it.
Its a discontinued practise in smaller boats especially petrol engined inboards.
PS. Why would you say you must be 'talking out your ass' because I've never come across it?

Go and order a new crate 350 from PCM, Mercruiser and all the others and when they ask if you'd like a counter rotating motor, tell them they're idiots :armsup:

PCM website says LH or RH PROP rotation with the output through a 1:1 transmission. NO mention of reverse rotation engine.
This is getting off topic and I may very well be wrong but I can't find anything to say the engines run backwards.

Is there any reason why you couldn't flip the rear diff as per standard practise, and rotate upsidedown the front third member, but leave the housing as is so the drop suits the Navara transfer? Surely this would be easier than flipping the front and then moving the diff again.

Yes, its only the diff centre that needs to be flipped, whether you flip the centre only or the whole diff housing is irrelevant, as long as the diff centre is upside down to its normal position it will work in a rear engine set up.

have to flip the front cover of the diff housing too, or mightaswell cut it off and weld on a stronger cover for it anyway
