Chris & Tom Thorn & Dave again spent the weekend on site starting to remove the removable rad grille section and the air filter frame in the passageway, to get at the motor blower inside. Chris B joined them today & by the end of the day, they had unbolted & removed the blower snail housing out through the hatch for cleaning. It is hoped the motor itself will follow soon, but due to it's weight, it will probably have to be lifted out through the roof. Ian & Pete removed all the cam followers from the power unit's B side for cleaning & to blow out the oilways with the compressor. I rewired part of the rear of the cleaned wheelslip relay board, using new brass nuts & bolts, as the original cable mounting bolts had all been sheared off sometime ago. Once the wheelslip resistors have been cleaned, and I have verified the relays are still working, the board will be reassembled & can then be fitted into the elec cubicle.
