You can also find on the side of the block of this engine, on its raised machined area, a stamp that says K25. We can also help identify the age of other brands of forklifts. This engine also has a hydraulic/timing cover and a set of hydraulic pump drive components. for assistance identifying the age of Hyster or Yale forklifts built prior to 1995. The letters “I,” “O,” and “Q” are not used since they are easily misread. Since 1995, the last character (letter) of a Hyster or Yale forklift serial number designates the year of manufacture. OSHA states: “Do not operate a truck with an illegible or missing nameplate.”

In addition to the serial number, the capacity plate also lists the model number, fuel type, and various capacity ratings at different lift heights. The capacity plate, also known as a name plate or data plate, should be attached to the forklift near the operator seat (sit-down forklifts) or within easy eyesight (stand-up forklifts). The first step in identifying the age of a Hyster or Yale forklift is to locate the serial number, which is stamped into the capacity plate.
