Need to rebuild the 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 quality parts that we replace in every governor rebuild during our remanufacturing process.
The 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).
Included in this kit are all of the normal wearing components, gaskets, seals, and bearings that are typically needed during a governor rebuild. Here is the full list of Genuine OEM Caterpillar components included in this kit.
