Evening All,
Back from the big city, took the head in for the hardened seats. Last head I was involved in we installed Detroit Diesel 92 Series valve seats. This time I think its a Perkins, just depends on whats available. I will order 92 series seats to use for future heads though, only 6 bucks American from my supplier.
Two weeks for the head to be ready, the only machine shop we have locally has only one self trained machinist, the rest are welders by trade, so it can take time, quite a backlog. Gives us plenty time to get the lower half of the engine ready and painted for reassembly.
Paid for 2 ST5s with AVRs and an extra AVR for my ST12 attached to my Power Anand 16/2. Gonna test out how much the AVRs knock the flicker out for myself. Planning for one to go to VA One and the other to my personal unit for either my workshop or my home in Nassau. All these generator related things are from Central Georgia Generator. Will not see the heads until the middle of June maybe, alternate shipping arrangement to get them to The Bahamas.
As for the duct going over the intake and exhaust, looking at the flange on the top edge of it, Id assume it was the beginning to duct the hot air from the engine room. Possibly to stop overheating the air in the room it was in if there wasnt a great supply of air. Suck cold air in, and blow hot out the top or side. My theory at least, only seen the last 5 VAs I was involved with saving with them on before.
No new pics, but more soon hopefully. Engine is so clean its looks like its gonna be just taking it apart to satisfy me that everything is correct, not that anything is wrong.
