Diesel Specs is the leader in engine specifications reports. Our spec sheets contain torque specs, valve lash settings and other necessary information to complete an engine rebuild. Not only do we provide specifications for diesel engines, but we cover gas engines. There are hundreds of engines from a variety of engine manufacturers in our database and we are constantly adding more.

If you don't see your engine please contact us. We may be able to track down the specs that you need. The rarity of the engine specifications requested can affect response time. We appreciate your patience.
