Paul Evans - Internal Fire Museum of Power
Engine partly stripped. Spent a number of years in a seized condition with many parts missing. Large number of new replacement parts with the engine.
Estimate 95% complete
Flywheel end is frost damaged around the skull. Head removed and crack ends drilled, welded and sealed with Belzona.
Timing end head removed and inspected.
Replacement head gaskets made in Klingersil as the originals were not useable.
One new sprayer fabricated to match the original as the two new sprayers that came with the engine had problems with the ball seat in the sprayer.
Improvement but 20 thou nozzles blocked quickly on both sprayers due to the lack of inline filters to the pumps.
Noise from the governor area when running - governor stripped and checked but no obvious wear found. The pump drive eccentric strap had witness marks showing it had been hitting the main bearing cap. The eccentric was moved to give clearance.
Big ends checked, No 1 clearance tight so stripped and found to have picked up slightly.
