Does anything need to happen other than bolting the A12 flywheel to the motor?
The A12 fly is thinner than that of the A15 so I was wondering if anything else needs to happen when installing. Thanks.

Yes, thinner flywheel means the Release Bearing needs to travel a different amount

To restore the correct distance (assuming it was all working correctly before swapping flywheel):
* Remove and discard the Engine Plate (if it is equipped with one)
OR
* Change the original-length Bearing Sleeve to a short one


The normal combination of A12 flywheel and 56A gearbox (regardless of engine) is:
* No engine plate
* Short sleeve (H50/120Y type)
OR
* Engine Plate
* Normal sleeve (H10/B110 type)

Awesome..
So it was working before I swapped the flywheel (56A + A15 w/ A15 fly)
So all I need to do is take the engine plate out?

That's my guess ... have you driven the car since swapping flywheels? What symptom are you experiencing, like grinding gears or clutch slipping or shifter is stuck

Havnt driven it.. Or started it. as of yet.
Just wanted to get this info before I get to far into it.

Would you know if it is possible to remove the engine plate with out taking the motor out?

Sure, it only requires removing the flywheel, which can be done with the motor in the car (remove gearbox first)

Awesome.
Thanks dude. Your a great help :)

Okay mate. Hopefully you see this comment.
Just got the ute going.

Occasionally grinding gears whilst going through them..
Grinds second gear on downshift pretty bad.
And there's a massive bang when I take off in third..

Sound like I need to remove the engine plate.
Also I think I might have put the A12 clutch in there Insted of the clutch from the 5 speed. :S

4-speed and 5-speed clutches are the same. A12 and A15 clutches are now the same, sold by Nissan and others (originally, A12 clutches were lighter duty, which would not cause grinding or banging, but might cause slipping if you used a light-duty clutch on a high-torque engine). Have you adjusted the clutch cable to spec?

If it doesn't grind going from neutral into first gear, and it goes into first gear smoothly, then the combo is working correctly
