Supplied by AirComParts as part of the ACS Kellogg clone replacement line.\u003c\/p\u003e\n\u003cp\u003eOn a 352 or 462 the intake and exhaust valve assemblies are clamped into the cylinder head by a hold-down rather than bolted through. The hold-down takes every pressure pulse the valve makes, so it is a wear item: once it is distorted, cracked or pitted at the seat face the valve no longer sits square, and the pump loses pressure, runs hot and blows gaskets. If you are already in the head, renew the hold-down with the valve.\u003c\/p\u003e\n\u003ch3\u003ePart reference\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eK4012:\u003c\/strong\u003e hold-down, low pressure, 352 and 462 pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eK4013:\u003c\/strong\u003e hold-down, high pressure, 352 and 462 pumps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePump fitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e352 \/ 352TV \/ 352TVX:\u003c\/strong\u003e 10 HP, two-stage, two-cylinder, 34 CFM at 175 PSI, 645 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e462 \/ 462TV \/ 462TVX:\u003c\/strong\u003e 15 to 25 HP, two-stage, four-cylinder, 81.5 CFM at 175 PSI, 775 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDo the screws at the same time\u003c\/h3\u003e\n\u003cp\u003eThe eight valve hold-down screws for the 352 and 462 are a separate part, AirComParts K4365. Hold-down screws stretch and the heads round off after repeated removal, so it is worth fitting a fresh set whenever the valves come out. The matching valve gaskets are K4360 (HP), K4361 (LP) and K4366 (cylinder to head).\u003c\/p\u003e\n\u003cp\u003eAirComParts low-pressure and high-pressure valve hold-downs for Kellogg-American 352 and 462 air compressor pumps, stocked alongside the complete 352 and 462 valve group: valve assemblies, gaskets, hold-down screw sets, cylinder head plates and pistons.
