Removing governor on 8.2L Detroit
Hey everyone, first time poster
I have a 1987 Ford B700 school bus I am converting to a camper but I need to remove the governor and was wondering how much work that would be and if I could do it myself or if it is a job I should hire out and if so how much that would cost
The engine is a 1986 or 87 8.2L GM/Detroit Diesel non-turbo with 151k miles, and with the governor it has on now it can not go faster than 45-50 which will just not work for cross country road trips, I bought it from the NC school system so that it is why it has the governor
Anyone know how to take it off without damaging anything? Thanks for the help

If the engine is mechanical it should use a method of intercepting the throttle linkage. Connecting the in/out ends would bypass it.
Or you could just remove the cover and see what makes it tick (please post a picture if you do!).
First, make sure your tires are rated for the higher speeds!

You seriously call yourself "tireman" and don't even know every tire has a speed rating?

Well FI I can tell you the maximum speed listed in the technical data you posted is something thats been added since I left the business in 06, but as I said they don't have a speed rating system like passenger tires where different letters = different mph, The medium truck info you posted from Bridgestone showed 75 mph max for every tire listed But for the sake of not Hijacking this thread anymore, I will not argue with you. We'll just say you're a Genius and know everything

Here is the same site from May 2006.

MAXIMUM SPEED RESTRICTIONS ON HIGHWAY SURFACES
Tire load capacity and required inflation pressure vary with vehicle speed, and therefore, must be adjusted for maximum vehicle speed.
Many states have increased commercial vehicle speed limits since repeal of the Federal maximum speed limit. Commercial vehicle speed limits are as high as 75 mph in some states.
The maximum loads published in the Tire & Rim Association (TRA) Yearbook are based on a maximum speed of 65 mph. For speeds of 66 mph to 75 mph, load reductions and pressure increases are specified in the TRA guidelines. With these load reductions the most common sizes of truck tires are inadequate to carry the 6,000 lb. required for a standard 12,000 lb steering axle at 75 mph. Tables 1 and 2 contain 2005 TRA Yearbook guidelines.

My main point of all this is that since the school system's vehicles are governed to 45mph they may have "cheaped out" and found tires with lower speed ratings to save budget expenditures. HikerMan needs to do the research on his brand/size of tires and make sure they're safe for 65-75mph.
