g'day mate

Is the navara a TD27?? or a petrol? Now the prob lays in which i think the terrno is electronic i think. If not is a straight forward conversion.. A bit more info in reguards to the navara and the terrano will make it easier

d21 navara diesel 2wd man td27

d21 terrano diesel 4wd auto td27t

my problem is the flywheel from the navara doesnt bolt to the terrano motor,do i need to use a terrano turbo manual flywheel?

want to use the terrano td27t with my 2wd gearbox-it does bolt on,just need ot suss out a clutch

Just get a flywheel to suit the terrano crank and mix and match a pressure & clutch plate. But in saying that the spline count on the terrano manual and navare manual is brob the same.

OR redrill navra flywheel to suit new motor that way you keep the same clutch,, but would get a heavy duty clutch kit.

Personnaly i would just get a 2nd hand terrano flywheel and mix and match clutch parts to mate it to your g/box.. But im sure you will find that both manual g/boxes share the same input spline count..

do you think it matters that the terrano is an ex auto gearbox?

like the crankshafts arnt different betweeen auto and manual destined motors?

a guy i know is a nissan specific wrecker and hes looking for one,but hasnt had any luck so far

have you done the conversion yourself?

Yeah mate,, i cant see a diesel engine not having a thrust brg on the crank.. SOME early petrols didnt have crank thrust brgs becoz an auto has no clutch that pushes on the crank..

NOW i cant imagine that it would be that hard to find a manual terrano.. but you will find that if worst comes to worst you could re-drill ur orginal flywheel to suit. Are there the same amount of bolts in each? Most likly it only the PCD that has changed or where the flywheel sits over the end of the crank.

I havent specifically done this conversion but ive re-drilled a lot of flywheels cranks and bell-housings to do one off jobs. Yes the easiest way put of it would be to get a hold of a flywheel to suit..

Try bolting a VW combi van g/box to a L16 nissan motor,, Had to make adaptor plate, re-drill flywheel to suit nissan crank, ( still used H/D VW clutch this way)

If you can get some pics up i might be able to help you more

Sure can

my Navara flywheel is the same bolting pattern,its just that there is a small lip on the mounting surface that 85mm in diameter and prevents it from slipping over the Terrano crank end which is 95mm in diameter.

the other problem i have is the terrano crank sticks out from the end of the block a further 5mm

please see pics,also note that ruler does not read right due to camera is so close.its more there to show what i measuered.

Much better with pic!!

Now this might seem like a silly question but i got hug up on this when i was about 14y/old with a L18 dato motor that was an auto..

That extra bit on the end of your terrano crank is a spacer, give it a few light taps with a hammer... Im not kidding i think its that simple because you look,, how would you change the rear main seal??? Its larger in diameter than the seal and i know that they have a conventional oil seal.

You will find a lot of engine that were oringinally manuals then manufactures started putting autos behind them just made up the spacer to move the flex plate, being a lot thiner than a flywheel..

The spacer is prob just rusted onto the crank a bit. The dowel you see in the end of your narvara crank will be whats stuck the spacer to the crank on the terrano motor...

Hope this helps,, but im 99% sure that all that is, is a spacer
