I have posted this on the Interceptor list but will post here as well as some poor soul may find it helpful.
Just in case someone is going to do this in the future (or if I forget)
here is the easy way to pull the powerunit on a Rickman Enfield.
Remove the primary side cases, exhaust, the horn, top engine mounts
and the forward engine mounts. The lower stud will remain
in place.
Remove the TS frame to rear engine mount, two bolts on frame
one through back of cast mount. You can leave the DS untouched.
Place jack under the engine itself.
Remove the four nuts that retain the rear engine mount casting.
Remove the cast mount to rear and out.
Double nut the studs for same and remove all four.
Remove the bottom gearbox to frame bolt.
Lift and remove gearbox to TS.
You can now tip the engine over to the TS to clear the frame
top rails and then lift clear.
As I was working alone and the lump is bloody heavy for an old
fool so I used a cargo tie down strap to lift it out.
Lots of fiddly stuff to do but actually it went easily enough.
You probably do not have to pull the carbs off or the timing
cover but the lump is going to be broken down so in my case
it made sense.
