NOTE: Tolerances of the battery compartment are +3 and 0 mm (+0.12 and 0 in.). The battery size column shows the size range that will permit the battery to still fit into a battery compartment. NOTE: Battery compartment length is front to back. Width is side to side. The "length" dimension of the battery must fit within the battery compartment front-to-back dimension with a clearance of 0 to 13 mm (0 to 0.5 in.) maximum. Battery width must fit within the battery compartment side-to-side dimension.

WARNING

The battery must fit the battery compartment so that the battery restraint system will operate correctly. Use only batteries with the correct length shown in this table. Adjust the spacer plate to prevent the battery from moving more than 13 mm (0.5 in.) forward or backward.

NOTE: With reference to mast mounting assembly drawings, section B-B dimension "X" must not exceed 20 mm (0.8 in.) in all rod end configurations. Back tilt tolerance must be obtained for all rod end configurations. In some truck/tire configurations, some rod end configurations may not achieve the "ref only" forward tilt tolerance. But forward tilt is still satisfactory.

Drive Axle Repair

General This section has the repair procedures for the drive axle/speed reducer/differential.

Drive Axle Repair REMOVE WARNING PUTTING THE LIFT TRUCK ON BLOCKS The lift truck must be put on blocks for some types of maintenance and repair. The removal of the mast, drive axle, battery, or counterweight assemblies will cause large changes in the center of gravity. When the lift truck is put on blocks, put additional blocks in the following positions: • If the mast and drive axle are removed, put blocks under the counterweight so the lift truck cannot fall backward. • If the counterweight is removed, put blocks under the mast so that the lift truck cannot fall forward. Put the lift truck on blocks on a solid, even, and level surface. Verify the blocks or stands have enough capacity to hold the lift truck. Use additional blocks next to the tires as necessary to prevent movement of the lift truck. Verify the lifting devices used during repairs can lift the weight of the parts and assemblies.

Periodic Maintenance 8000 YRM 1442 for lift truck models • ERC16-20VA (ERC030-040VA) (A969) 3. Remove the covers or plates and rollers from bottom of battery compartment. See Frame 100 YRM 1342 for procedures. 4. Remove the mast assembly. See one of the following service manuals for procedures. Mast Repair, 2-, 3-, and 4-Stage Masts 4000 YRM 1338 for lift truck models • ERC22-35VG (ERC045-070VG) (A968) Mast Repair, 2- and 3-Stage Masts 4000 YRM 1441 for lift truck models • ERC16-20VA (ERC030-040VA) (A969) 5. Disconnect the brake line connecting the master cylinder to the manifold located on top of the drive axle assembly. See Figure 1.

See the Operating Manual or Periodic Maintenance section for your lift truck model, for the procedures to put the lift truck on blocks. 1. Place the lift truck on blocks. The procedure for placing the lift truck on blocks may be found in the Operating Manual or one of the following service manuals Periodic Maintenance 8000 YRM 1364 for lift truck models • ERC22-35VG (ERC045-070VG) (A968) Periodic Maintenance 8000 YRM 1442 for lift truck models • ERC16-20VA (ERC030-040VA) (A969) 2. Remove the battery from the lift truck. See How to Change Battery in the Operating Manual or Periodic Maintenance 8000 YRM 1364 for lift truck models • ERC22-35VG (ERC045-070VG) (A968)

NOTE: Use a lift truck to support drive axle and traction motor as a unit or use a transmission jack under the traction motor and a floor jack under the drive axle during removal.

NOTE: Perform Step 9 only if lift truck is equipped with optional drip shield. 9. Remove capscrews, nuts, and drip shield from frame, allowing access to traction motor. NOTE: Perform Step 10 if lift truck is equipped with an automatic park brake. 10. Disconnect automatic park brake from traction motor. See Figure 3.

11. Slide floor jack under the drive axle assembly differential. Raise floor jack until it supports the weight of the drive axle assembly. NOTE: The traction motors are in different configurations for different applications of the lift trucks. Traction motors weigh approximately 90 to 140 kg (200 to 310 lb). Make sure transmission jack has capacity to hold traction motor. 12. Slide transmission jack under traction motor. Raise transmission jack until it supports the weight of the traction motor. 13. Remove the four axle mounting bolts, washers and nuts from the drive axle assembly. See Figure 2. NOTE: Remove drive axle and traction motor as a single unit. 14. Roll the floor jack and transmission jack with drive axle and traction motor from underneath the lift truck. NOTE: Forklift trucks with 4-Stage Quad Mast will have an optional spacer between the drive axle mount and the frame’s mounting bracket. 15. If lift truck is equipped with a 4-Stage Quad Mast, remove the spacer from the drive axle mount. Repeat for other side. See Figure 4.
