When the spring loses its tension or snaps, the chemical injector fails to cycle, leading to uneven nutrient delivery, stunted crop growth, or total system shutdown. With peak summer demand nearing and global supply chains remaining unpredictable, waiting for a failure to happen is a risk to your project deadlines. Maintaining a backup stock of these essential components ensures you can perform immediate roadside or field repairs, keeping your clients satisfied and your systems running without the frustration of long lead times or back-ordered shipments.\u003c\/p\u003e\u003cp\u003eThe Dosatron D128R Wishbone Spring is engineered with higher fatigue resistance than generic aftermarket alternatives, ensuring a more reliable snap-action movement within the motor assembly. By using genuine OEM parts, you reduce the frequency of maintenance intervals and prevent the premature wear of connected internal components. This precision-calibrated spring allows your crews to restore factory-spec dosing accuracy in minutes, saving billable labor hours and avoiding the high cost of total unit replacement. Staying well-stocked with these high-wear items provides you a competitive edge by minimizing downtime and proving your reliability to commercial and agricultural clients alike.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-Grade Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eDosatron International\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eD128R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eD14MZ and Select D128 Series Injectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Type\u003c\/td\u003e\n\u003ctd\u003eWishbone Actuator Spring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eInert Metallic Finish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThe D128R Wishbone Spring is specifically sized for the D14MZ series and related 14 GPM models; however, we carry a full inventory of Dosatron seal kits, check valves, and piston assemblies.

Use a standard non-marring tool to access the motor assembly and inspect the surrounding plastic housing for debris or wear that could interfere with the spring movement. Always refer to the manufacturer schematic to ensure the spring is seated properly in the actuator grooves, as incorrect positioning can lead to cycling failures or decreased dosing accuracy.\u003c\/p\u003e","brand":"Dosatron","offers":[{"title":"Default Title","offer_id":52158387454241,"sku":"120656","price":6.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/120656_PR.png?v=1766409777","url":"https:\/\/asiwsupply.com\/products\/dosatron-d128r-wishbone-spring","provider":"ASIW","version":"1.0","type":"link"}
