Description

General This section has a description and the service procedures for the parts of the frame. These parts include the frame, counterweight assembly, overhead guard, hood and seat assembly, access panels, and label positions. The procedure for removing the traction motor is also described in this section.

Description MAIN FRAME The main frame is a single weldment. See Figure 1. The main frame has mounts for the following: • Counterweight • Overhead guard, • Battery restraint and hood • Tilt cylinders • Steering axle • Drive axle assembly • Cowl assembly • Floor pedals and floor plates • Side step and fender weldments • Hydraulic tank • Pump and motor assemblies (steer, lift, and traction motors) • Control valves, and the levers The hood is part of the operator and battery restraint system. The seat is part of the operator restraint system. The floor plates can be removed for access to the traction motor. The panels on the sides of the battery compartment can also be easily removed. The hydraulic tank, lift pump motor assembly, and the steering pump motor assembly are in a compartment between the battery and the counterweight. The SCR (silicon controlled rectifier) or transistor electronic controllers and contactors are in the top of the counterweight. The top cover of the counterweight can be removed for access to the controllers and contactors for early model ERP20-30ALF (B216) lift trucks. See Figure 2. The rear cover of the counterweight can be removed for access to the controllers and contactors for later model ERP20-30ALF (B216) trucks and ERP2030ALF (ERP040-060DH) (D216) trucks. See Figure 3. There are two main frames for lift trucks made for use in North America and two main frames for lift trucks made for use in Europe. The frames are different because of the different battery compartment sizes. There are two battery compartment lengths. The battery compartment widths are also different for Europe and North

America. See Battery Specifications, at the back of this manual.

WARNING The battery must fit the battery compartment so that the battery restraint will operate correctly. A loose battery can cause serious injury and property damage if the lift truck overturns. Adjust the spacer plate to prevent the battery from moving more than 13 mm (0.5 in.) forward or backward.

WARNING Maximum clearance between the battery and battery compartment width is 13 mm (0.5 in.). Maximum clearance between the battery and the spacer plate is also 13 mm (0.5 in.). The Battery Specifications chart shows the minimum size compartment allowed. The weight of the battery is a large part of the counterweight system on an electric lift truck. Make sure that the battery is within the weight limits indicated on the nameplate. Each model of lift truck has a cast-iron counterweight that provides the additional weight necessary for the indicated capacity.

OTHER FRAME WELDMENTS These frame parts are the right-hand and left-hand side step and fender weldments, and the cowl weldment. See Figure 1. Each part is a weldment fastened to the main frame to make the frame assembly. The cowl weldment is a mount for the front of the overhead guard (see Figure 2 and Figure 3), the steering column assembly (see Figure 4, Figure 5, and Figure 6), the release linkage of the parking brake, and the instrument panel with light switches. The display panels for these models of lift trucks are mounted into the instrument panel. See Figure 4, Figure 5, and Figure 6.

The spacer plate must be adjusted for a maximum clearance of 13 mm (0.5 in.) with the battery against the rear bulkhead. There must be some clearance to allow battery removal. See the section Periodic Maintenance 8000 YRM 552 for both early and later model ERP20-30ALF (B216) trucks and Periodic Maintenance 8000 YRM 1060, for ERP20-30ALF (ERP040-060DH) (D216) models, to remove the battery and adjust the spacer plate.

A battery restraint system is installed as a safety device. See Figure 7. The function on the battery restraint system is to hold the battery in the battery compartment in case of a tip over. Part of the battery restraint system is a battery restraint rod at the rear of the battery compartment. See Figure 7. This restraint rod extends over the rear edge of the battery case to help hold the battery within the battery compartment during a tip over. A handle is used to move the restraint rod. The handle of the battery restraint must be in the DOWN position to close the hood. The handle can be moved to the DOWN position only after the restraint rod is extended over the battery. The restraint rod can only be retracted when the hood is in the UP position.

WARNING The battery must fit the battery compartment so that the battery restraint will operate correctly. A loose battery can cause serious injury and property damage if the lift truck overturns. The battery must not be able to move more than 13 mm (0.5 in.) forward, backward, or side to side.

Traction Motor Replacement

100 YRM 582

Traction Motor Replacement REMOVE This procedure will show the removal of the traction motor from the speed reducer with the drive train installed in the lift truck. See Figure 17, Figure 18, and Figure 19. For repair procedures to the traction motor, see the section DC Motor Maintenance 620 YRM 294 for all lift truck models or the section AC Motor Repair 620 YRM 1053 for lift truck models ERP20-30ALF (ERP040060DH) (D216). NOTE: The traction motor can be removed separately or as a unit with the drive train. Removal with the drive train requires the use of a floor jack and is more difficult. The lift truck must be on blocks with clearance for the jack and traction motor to be removed as a unit. The hydraulic lines from the hydraulic tank must also be disconnected if this method is used. Remove the traction motor from the speed reducer and lift truck as follows (see Figure 17): 1. Put the lift truck on blocks for easier access to the bottom bolts between the traction motor and the speed reducer. 2. Disconnect the battery connector and remove the key from the key switch. Remove the floor plates. NOTE: It is not necessary to disconnect the hydraulic line from the master cylinder to remove the traction motor. If the hydraulic line is not disconnected, it will not be necessary to remove air from the brake system after installation. The master cylinder has a cap that does not leak, so it is not necessary to remove the reservoir. 3. During the removal of the following items, make sure to install plugs in hydraulic lines that are disconnected. Install a tag on all wires or cables for correct connection during installation. Do not disassemble the pedal assemblies any more than necessary for clearance to remove the traction motor.

INSPECT WARNING Special procedures must be followed when large leaks or other repairs need welding or cutting. All work must be done by authorized personnel. If the tank is cleaned inside of a building, make sure there is enough ventilation. See the following manuals for additional information: • Safe Practices for Welding and Cutting Containers That Have Held Combustibles by the American Welding Society, F4.1 - 1999.

The hydraulic tank is a separate sheet metal tank and can be removed from the lift truck if necessary to check for leaks or for replacement. Repairs for leaks in the hydraulic tank can require special procedures described in the next paragraphs. The most common cause of leaks is from rust caused by the moisture of condensation or a plugged hydraulic tank breather. Drain any water out of the tank by removing the drain plug and letting the tank drain until there is no water in the oil.

CLEAN WARNING When cleaning the tank, do not use solutions that make dangerous gases at normal temperatures or when heated. Wear eye and face protection. Protect the body from burns.

Steam Method

Chemical Solution Method

When cleaning with steam, use a hose with a minimum diameter of 19 mm (0.75 in.). Control the pressure of the steam by a valve installed at the nozzle of the hose. If a metal nozzle is used, it must be made of a material that does not make sparks. Make an electrical connection between the nozzle and the tank. Connect a ground wire to the tank to prevent static electricity.

If the tank cannot be cleaned with steam, use the following procedure:

Use the following procedure to clean the tank with steam: 1. Remove all the parts from the tank. Install the drain plug. 2. Fill the tank 1/4 full with a solution of water and sodium bicarbonate (baking soda) or sodium carbonate. Mix 0.5 kg (1 lb) per 4 liter (1 gal) of water.

WARNING Compressed air can move particles so that they cause injury to the user or to other personnel. Make sure that the path of the compressed air is away from all personnel. Wear protective goggles or a face shield to prevent injury to the eyes. 3. Mix the solution in the tank using air pressure. Make sure all the surfaces on the inside of the tank are flushed with the solution. Drain the tank. 4. Put steam into the tank until the tank does not have odors and the metal is hot. Steam vapors must come from all the openings. 5. Flush the inside of the tank with boiling water. Make sure all the loose material is removed from the inside of the tank. 6. Make an inspection of the inside of the tank. If it is not clean, repeat Step 4 and Step 5 and make another inspection. When making inspections, use a light that is approved for locations with flammable vapors. 7. Put plugs in all the openings in the tank. Wait 15 minutes, then remove the inlet and outlet plugs. Test a sample of the vapor with a special indicator for gas vapors. If the amount of flammable vapors is above the lower flammable limit, repeat the cleaning procedures.
