Well I had a rummage around and found this one I’ve had for a few years as a replacement for the buggiscopic, it came off a suitcase conveyor from the airport

it’s also what is in my jcb520-40 a 4 cylinder Perkins

So had to remove the auto transmission and a few other bits like the old mounts to be left with this after the torque converter had been removed

So pulled the pump from the old motor and need to mate the two together

ive got to make an adaptor out of the drive from the Perkins to the doughnut pump drive

so after a hour on the lathe a bit of careful measurements managed to get the drive mounted on the new engine

not too bad for a mornings work (surprising what you can do without any distractions)

got to make an adapter to mate the two together then I can mount the pump on the engine then concentrate on the engine mounts (which are nowhere near where they need to be)
hope your happy now
