This is a replacement kit for a pressure control valve in a Hydro-Gear hydrostatic transaxle assembly used in riding lawn mowers. It includes a spring, ball and pin that work together to limit the pressure of the fluid flowing between the fluid power system and the transaxle case. After fluid flows through the system, lubricating the pistons and other parts, a charge pump pushes it back into the flow. If the fluid isn't needed to increase the pressure in the system, the unneeded fluid is passed back through the charge relief valve into the transaxle case. The charge relief valve may need to be replaced if the engine becomes noisier than usual, if the transmission fluid is dirty, if the spring becomes worn or damaged or if the check ball isn't seated properly. This requires disassembling the center section of the transaxle assembly and removing the pin, spring and ball. This can be accomplished by using a clean, flat screwdriver to depress the charge spring, allowing the pin to slide out. This kit can be used in several brands of lawn mowers including Endore, Scag, Hustler Turf and Big Dog. This is an OEM part sourced directly from the manufacturer and is sold individually.
This is a replacement bump knob for a gasoline-powered string trimmer used for cutting light weeds and edging lawns and driveways. The bump knob is a hard plastic attachment that is snapped onto the end of the cutting head assembly of the trimmer. Also known as a bump feed knob, this part releases about one inch of line or string from a spool inside the cutting head assembly each time the operator taps it on the ground or pavement. This enables the operator to keep operating the trimmer without stopping to advance a worn or frayed string manually. Pushing down on the bump head also releases the end of the trimming line so a new spool of line can be installed. The bump knob is simple to install, by snapping it onto the bottom of the gearbox shaft. It may need replacing due to normal wear and tear or after cracking or scraping on hard surfaces. This part fits several models of Craftsman and MTD string trimmers, also known as weed whackers. This is a genuine OEM part sourced directly from the manufacturer and is sold individually.
