Time to install the assembly then. Well, you can see it went in okay but it took a while to get in.... The retaining nut and washer came off very easily but the driven gear wouldn't pull out with a magnet. Or a pair of pliers. Or welding rod slid under the gear and pulled up.
So, time for a bit of thought and a coffee. Key in the ignition and cranked it over a couple of times and the gear rises up the shaft easily and could be pulled out.
Dropped the new assembly in but the top plate wouldn't settle down fully. Slight panic - was the shaft too long? A dry assembly without the "O" ring showed that it was okay and that's how it has to stay for the time being. Unfortunately the engineering company removed the AHM one when machine the the top cover and misplaced it so I need to get a new one. I attempted to use one from the old top plate but it was too wide and had to be cut down. Even then it was too thick or the groove in the cover plate too shallow as it just wouldn't fit into the engine with the seal in place.
So now I'm waiting for a new one from AHM now... Hope Adie stocks them!
