Blimey that's a bugger! Buy the whole thing. And hope there's no damage. Prime prime and prime again.
 
I've got an old front cover with that plate on it but I wouldn't risk it. But your welcome to have the cover ( or the whole thing) for postage. Wait mine is gems but I don't think it matters TBH.

I'm with grrrrrr. They should be silly money. But there actually reasonable. Hobourn the original maker went bust. But the new ones are identical and must be made at the same place.( Boxed sh#_&part)
 
Hobourn Eaton made the pump internals, don't know about the main casing.
We had a 'spare' front cover but I'd not risk a secondhand piece unless it was surface ground flat first.
New cover assembly was £200+ last time I looked. (£193 plus carriage and VAT)
They are listed as part of the Dana Corporation.

Very easy just line up the square dots and push on to the crank woodruff. The cam is just held with a notch on cam and gear. And secured with a bolt( on the gems anyway)
Different styles of timing gear is available. Floppy or stiff matron? Not sure what's best TBH.or where from. But the cam sensor is triggered from the cutout in the top gear meaning it's Thor or gems specific.

As Johnnyb70 alluded to above, the timing gears are identical in number of teeth between Thor and Gems engines, but the gears are easy to identify, GEMS has equal cutouts in the gear face, Thor has unequal shaped cutouts.

Strangely enough, a Thor engine will run with a GEMS timing gear, but it is better with the correct one!
