3406 B/C Governor Rebuild/Update/Upgrade Kit For Truck Engines

Description

Need to rebuild your governor on your 3406B or 3406C truck engine?  Look no further than our governor rebuild kit!  This kit works for all late style 3406B or 3406C truck engines and includes all of the same parts that we normally replace in every governor rebuild during our remanufacturing process.  This kit is updated with the latest style flyweight carrier, the matching late style flyweights, and late style governor races (these MUST be replaced as a set, many governors fail from mixing late style and early style components).  This kit is also UPGRADED with a new 8M-9141 Governor Spring, which will provide improved throttle response and raise your rack-setpoint/high idle to govern your engine at approximately 2100 RPM under full load (high idle with no load will be higher than 2100 rpm, this is normal.  For optimal results, set your rack setpoint/high idle with a proper rack-setpoint indicator after your governor rebuild).  Included in this kit are all of the normal wearing components, gaskets, seals, and bearings that are typically needed during a governor rebuild, please see the list of components below.  Some O-Rings are not compatible with very early 3406B truck engine governor housings, if you are unsure if this kit is right for you, please ask us for a quote, provide your engine serial number, and we will do our best to accomodate you!
