Kubota b7100d. Engine question

[Pierrecnwl]

I have a b7100 with a d750d. Manual i found a part tractor but hst instead with 2500 hous less on the motor I suppose just the flywheel is different hopefully i didn’t buy it too fast?
Thaks for your advice

The flywheel and clutch should be identical between the two machines.
