Depends on whether it is a torque drive or a conventional clutch. If its a straight clutch, you need to remove the foot plates in the cab & then remove the bell housing upper half between the engine & gearbox. Tight getting out but comes out engine side. You will need to remove exhaust manifold for space. Then you have access to the drive shaft to the gearbox which has a splined collar that will slide over the shaft when the pins are removed. Also the clutch thrust yoke shaft needs to be removed. Lift away then & you engine should come out OK. If its a torque drive, you need to disconnect the torque unit from the flywheel bolt by bolt rotating the engine for each 1. Access is through a large bolt located beside the starter on the engine bell housing. Make sure the pump & front pulley connection is disconnected before attempting to lift. Also make sure the replacement engine is a good one!! You dont want to be doing this too aften. Replace the full clutch assy. & front & rear engine seals anytime the engine is out on these. well worth the cost.......you wont regret it. Good luck.
