Gearbox stuck on

[Chris306]

Right then lads I don't know if any of you have come across this before but the hdi box on my xud engine just will not come off at all, there's no driveshafts all the bolts are out an there's nothing attached holding it, I can get the box away from the block by about a good inch and a half and then it stops and won't go no further, iv tryed big hammer the ode special love stick ( big pry bar), I did also try playing with the clutch arm which seams to pull the box back on if twisted so to speak, this to me sound like the clutch fork holding the box on in some way, but I don't know what to do now to seperate the two.

Anyone shed a little light on this for me please
