25 Hydraulic Wet Kit Information WET KIT DIAGRAM SPEED OF FLOOR IN RELATION TO ENGINE RPM With a Fuller 3 or 5 speed transmission, a bottom mount 8% series 44/489 Chelsea power take off, and a Commercial P5 pump with a / gear, the floor movement in relation to pump output is as follows*: TRUCK RPM 950 RPM 70 RPM 430 RPM 750 RPM 900 RPM PUMP OUTPUT 30 gallon 40 gallon 45 gallon 55 gallon 60 gallon FLOOR MOVEMENT* 8. ft./minute.0 ft./minute.5 ft./minute 5.0 ft./minute 6.4 ft./minute * Above specifications are for KEITH drive unit with 80mm bore cylinders. These are approximate feet per minute only and should be used strictly as a guide. Note: Drive unit is not designed to exceed 60 GPM. 8/9/03 7.5

26 Hydraulic Wet Kit Information Transmission: This wet kit is designed for a Fuller 3 or 5 speed transmission. All of the following information applies to this transmission. (P.T.O. specifications may vary with other transmissions. Please check with Keith Mfg. Co. for specifications.) Oil: Chevron AW46 hydraulic oil or equivalent. PTO: Chelsea series 44/489 bottom mount (6 or 8 bolt) 8% power take off (electric over speed is highly recommended), or Muncie P.C. 65 with electric over speed. Pump: Commercial P5 A97BE (Spl.) 55 ( four bolt suction) with Anchor W4333 flange. Filter: Filter should be 0 to 30 micron on the return line. Filter should be a double element Zinga (or equivalent). Filter head #DF55. MF 5500 Filter element #LE0 or LE30 (The filter element should be changed after 6 hours initially, and then every 6 months thereafter. This may vary with the operating environment.) Hydraulic Reservoir: Should hold approximately gallon for every gallon per minute you plan to pump, i.e. 40GPM = 40 gallon reservoir. Reservoir should hold a minimum of 40 gallons of oil. Suction Line: Suction line from the tank to the pump should be no more than 5 in length and a minimum of inside diameter. Example: SAE00R4 (This type of line has a spiral wire to keep the hose from collapsing under suction.) Pressure line: Hose from truck to trailer should be 6 SAE00R. Return Line: Hose from trailer to filter should be 6 SAE00R. Hose from filter to tank should be /4 0 SAE00R. Pressure Relief Valve: Example: Cross #RDD Note: It is critical that this relief valve is set at ess no l than 800 PSI and no more than 3000 PSI. 8/9/03 7.6

27 Trouble Shooting GuideSwitching Valve Unloading Problem: Floor does not run at all. Check: All items on STARTUP check list:. Is your entire system plumbed to the plumbing diagram?. Pump: Will it pump 3035 GPM at pressure? 3. Relief Valve: Is it set at PSI? 4. Oil: Have you filled the reservoir? 5. P.T.O.: Is it engaged? 6. Quick Disconnects: Are they completely engaged? 7. Ball Valve: Is the ball valve on the drive unit closed? 8. Is the pressure line on the trailer attached to the pressure line on the tractor and the return line attached to the return line? The pressure and return lines must attach to their proper rtspo on the switching valve. Problem: Cycle starts then floor stops.. Specific trouble: Drivers side cylinder (#) moves toward the front of the trailer, center cylinder (#) moves toward the front of the trailer, passenger side cylinder moves toward the front of trailer; then the system stops. Solution: The threaded rod nuts on the switching valve are not adjusted correctly. Break the two nuts apart and adjust toward the rear of the trailer.. Specific trouble: All three cylinders move toward the rear of the trailer; then the system stops. Solution: The threaded rod nuts on the switching valve are not adjusted correctly. Break the two nuts apart and adjust toward the front of the trailer. (See note) 3. Specific trouble: Floor runs fine empty or with a light load, but will not cycle with a heavy load. Solution: This means that the nuts on the threaded rod are slightly out of adjustment or that you dont have enough hydraulic pressure. Repeat previous solutions. (See note) Note: If floor stops in the full rear position and the switching valve has switched, you may not have enough oil pressure. Less pressure is required to move the load than to pull the slats /3 at a time under the load. 8/9/03 7.7

28 Trouble Shooting GuideCheck Valve Unloading Problem: Does not cycle correctly.. Specific trouble: Cylinders (#) and (#) extend together toward the front of the trailer while unloading. Solution: The check valve at the forward end of cylinder (#) has malfunctioned. Replace the check valve.. Specific trouble: Cylinders (#) and (#3) extend together toward the front while unloading. Solution: The check valve at the forward end of cylinder (#) has malfunctioned. Replace the check valve. 3. Specific trouble: All cylinders extend together toward the front while unloading. Solution: The check valves at the forward end of cylinders (#) and (#) have malfunctioned. Replace the check valves. Loading Problem: Does not cycle correctly.. Specific trouble: Cylinders (#) and (#3) extend together toward the rear of the trailer while loading. Solution: The check valve at the rear end of cylinder (#3) has malfunctioned. Replace the check valve.. Specific trouble: Cylinders (#) and (#) extend together toward the rear while loading. Solution: The check valve at the rear end of cylinder (#) has malfunctioned. Replace the check valve. 3. Specific trouble: All cylinders extend together toward the rear while loading. Solution: The check valves at the rear end of cylinders (#) and (#3) have malfunctioned. Replace the check valves. Note: When empty, some trailers will cycle in sequence forward 3, then back 3, (instead of all slats moving back together.) This is not a malfunction; no repairs are needed. When a load is put on a trailer, the drag will cause the floor to sequence properly. 8/9/03 7.8
