The Hoses that connect to the Brake Reservoir are Too Long{4269} Caterpillar

Backhoe Loader:

416E (S/N: SHA1-UP; CBD1-UP)

Introduction

The problem that is identified below does not have a known permanent solution. Until the permanent solution is known, use the solution that is identified below.

Problem

The 5P-1442 Hoses that connect the brake reservoir to the master cylinder are too long. This is causing the hoses to kink.

2. Disconnect the reservoir (3) from the mounting brackets.

3. With the lid on the reservoir (3), tip the reservoir to the side.

4. Cut the reservoir lines at the outlets of the reservoir 35 ± 5 mm (1.39 ± 0.20 inch) (A) from the base. See illustration 2.

5. Pour the fluid out of the reservoir into a drip pan.

6. Stretch the reservoir lines straight from the firewall (4) .

   Note: Hoses should have enough extra length in order to allow the deflection of cab relative to the frame of the hood without pulling the hoses from the reservoir (3) .

7. Measure both reservoir lines at 245 ± 5 mm (9.6 ± 0.2 inch) (B) from the surface of the grommet on the firewall (4) and cut off the excess hose. See illustration 3.

   Note: Do not cut too short. Replace the hoses if the hoses are cut too short.

8. Remove the short hose lengths from the reservoir (3) .

9. Connect the hoses back to the reservoir (3) .

   Note: The hoses should be routed on top of the hydraulic tank and short enough length so the hoses will not kink.

10. Partially refill the reservoir (3) with fluid. Hold the reservoir (3) up for a few seconds in order to allow air bubbles to escape.

11. Use the bracket and bolts to mount the reservoir (3) onto the frame.

12. Tighten the hose clamps.

13. Refill the reservoir (3) with fluid.

14. Reassemble the cowling (1) and tighten the four bolts (2) .
