Raymond® Walkie Pallet Truck Maintenance Manual

Load Wheels Replacement

1.Lift the forks to maximum height and block them. See “Jacking Safety” on page 2-11.

2.Remove the axle set screw. See Figure6-48.

Component Procedures

Load Wheels

3.Drive the axle out of the load arm casting with a hammer and brass drift pin. See Figure6-49.

4.Push the wheel out. See Figure6-50.

5.If the bearings are to be reused, insert a brass drift pin into each end of the load wheel and knock the bearings out.

6.Install the bearings in the load wheel with the shields facing out.

7.Place the new load wheel upright on a flat surface. Position the bearing over the load wheel. Place a flat metal plate over the bearing, and hammer the bearing in place with a plastic mallet. Make sure the bearing is fully seated in the load wheel.

8.Align the wheel with the holes in the load arm casting.

9.Drive the axle through the load arm casting and wheel. Align the "dimple" in the axle with the set screw hole.

10.Install and tighten the set screw.

11.Lubricate the grease fittings if necessary.

Removal and Replacement

NOTE: It may be easier to work with the truck upside down. Remove the battery before turning the truck over. Some oil may leak from the hydraulic reservoir.

1.Extend the load wheel forks and remove the shaft connecting the wheel fork to the pull rod.

2.Remove the pivot pin locking bolt and drive the pivot pin out with a brass drift pin.

3.With the lower links out of the lift frame channels, the links can be separated and the pull rod removed from the link pin. Each link has one set screw at opposite ends. The link can be pulled apart without removing any other setscrews.

4.Press new bushings in the pull rods, if necessary.

5.Reassemble the pull rods on the lower links and press the links together so they will fit in the frame channel.

6.Reinstall the pivot shaft and the retaining bolt in the lower links.

7.Reconnect the pull rod to the wheel fork.

8.Place the truck upright and install the battery. Connect the battery. Check the reservoir fluid level. Test the operation of the lift frame.

Carrier Frame Linkage

The bushings on the upper links can be replaced by removing the links from one side at a time and pressing in new bushings.

1.To separate the lift and carrier frames, remove all electric connections before removing the links.

2.Remove linkages and lift the lift frame off the carrier frame.

Hydraulic Components

General Guidelines

To prolong the life of your Raymond Walkie Pallet Truck, adhere to the following guidelines:

•Keep all fittings and connections tight to prevent leaks. Be careful not to over-tighten brass fittings or they may become damaged or distorted.

•Before you remove any component from the hydraulic system, wash the component and surrounding area with cleaning solvent to prevent foreign matter from entering the system. Cap and plug all openings immediately.

•Whenever you remove a fitting with a pipe thread, use a sealing compound on the outside of the threads before you reinstall the fitting. (Never use Teflon® tape.) Make sure all parts are clean.

•When you install a hose assembly, make sure that it is not twisted when the fittings are tightened. Always use two wrenches on a swivel-type fitting—one to hold the fitting and the other to tighten the hose.

Adjustments

The only adjustment on the frame is a pair of lowered height stops. These stops consist of bolts with jam-nuts fitted on the frame just above the transmission assembly on either side of the lifting cylinder. The bolts should be adjusted so that when the truck is fully lowered, the bolt heads stop against the transmission frame evenly and both pallet forks are of equal distance from the floor.

Hydraulic Fluid

Proper Level

To prevent air from ente ring the lines, the fluid level (with the forks fully lowered) should be filled and visible to within 1 in. (2.54 cm) below the fill port elbow. See Figure6-51. Add the specified fluid if necessary. See “Lubrication

Equivalency Chart” on page A-2.

Changing Fluid

Store and handle the hydraulic fluid with extreme care to prevent moisture and foreign matter from entering the hydraulic system.

Contaminated hydraulic fluid is the major cause of hydraulic system failures. Any service equipment, such as containers, funnels and hand pumps, should be kept clean at all times. Cover them when not in use.

1.Lower the forks.

2.Turn the key switch OFF and disconnect the battery connector.

3.Remove the tractor cover.
