Finally found some time to work on the Bamford today after quite a long while.
Started by stripping off all the fuel system, fuel lines, injector, pump, filter etc, quick lube and clean.
Then all ancillary items from the head, rocker lubrication panels, front, rear and side panels, and exhaust. Again quick clean.
Then put the head on the bench and had a good look.
Found a lovely old wasps nest almost completely blocking and clogging the exhaust valve outlet and exhaust. Combustion chamber pretty sooted up. Inlet value pretty clear. After a good cleaning with wire brushes and various fluids it came up pretty well and both valves, seats and springs looking good. Decided not to completely remove valve assembly at this stage as it seemed to be functioning.
Piston looked quite clean and cylinder didn’t appear to have much wear or any pitting.
Drained oil. Removed all the bolts to allow the crank case to pivot, and had a quick look inside. Quite clean actually, everything well lubricated and operating smoothly.
On to the various covers I’d removed, degrease and clean and then even a bit of paint.
Many of the bolts don’t look original and some have been welded and repaired or modified. On inspection most of the brass fittings a well worn and again soldered, repaired and modified.
The pumps working well along with the injector, although the injector has a bit of pitting on the shaft.
The flywheels and associated governor system had a good clean and lube and appear functional.
At this stage everything looks to be in working order and hopefully it should only be a matter of getting the fuel and valve timing right to get her going. I hope.
Anyway plenty more cleaning and painting to go before she goes back together.
Last photo silver wheel/disc on the side of the fuel pump mount, advances/retards fuel timing, but which way?
