DISASSEMBLING THE TRACK CHAIN
1. Install the carrier and driver needed to disassemble the track chain.
2. Put the track chain on the table so that the track shoe surface is up and the pin half of the master link will be the first link disassembled.
IMPORTANT: Before pressing a bushing and pin out of the link, make sure that the drivers are aligned with the pin and bushing to prevent damage to the bores in the link.
3. Put the bushing in the first notch in the carrier and actuate one of the rams to press that pin out of a link.
4. Retract the ram and remove the link from the driver.
5. Actuate the other ram and press the pin out of the other link.
6. Retract the ram and remove the link from the driver and the pin from the bushing.
7. Move the track chain forward one bushing.
8. Actuate one of the rams to press the pin and bushing out of a link.
9. Retract the ram and remove the link from the driver.
10. Actuate the other ram to press the pin and bushing out of the other link.
11. Retract the ram and remove the link from the driver and the pin from the bushing.
12. Repeat steps 7 through 11 until the track chain is disassembled.
13. Remove the spacers from the pins and seals.
14. Remove the seals and rubber rings from the links.
15. Clean all parts in cleaning solvent.
16. Use a wire brush and clean the seal bore in each link.
17. Use a wire brush and clean the reservoir in each pin.
18. See Usage Guide for Pins and Bushings.

ASSEMBLING THE TRACK CHAIN
IMPORTANT: If a wet turn is being made, the parts of the track must be clean.
1. Remove the drivers used for disassembly and install the drivers used to assemble the track chain. The same carrier is used.
2. Use a straightedge and measure the offset of the drivers. The offset of the drivers must be 1.433 inches (36.4 mm). Add or remove shims between the long driver and base as required.
3. Adjust the relief valve for the track press to 5921 psi (40 825 kPa).
4. If a wet turn is being made, install a new plug in each pin.
a. Make sure that the bore in the pin is clean and free of any lubricant.
b. Lubricate the bore in the pin with Loctite Safety Solvent or water and soap.
c. Put the guide (CAS-1851-1 or CAS-1852-1) on the end of the pin and lubricate the bore of the guide.
d. Use the driver CAS-1851 and drive the plug into the pin. The plug must be approximately 0.39 inch (10 mm) below the end of the pin.
5. Make sure that there is a good chamfer on both ends of all the pins so that metal will not be removed from the bores in the links when the links are pressed onto the
pins.
6. The first link assembly to be assembled is the bushing half of the master link.
7. Install a bushing in the far notch. If the bushings are being turned, put the bushing in the carrier so that the mark made before disassembly is on top.
8. Install a link half on one of the drivers and actuate the ram to hold the link half against the carrier.
9. Install the other link half on the other driver and actuate the other ram until the link half touches the bushing. Check to make sure that the parts are even with each other.
10. Actuate the ram to press the bushings into both link halves.
11. Measure the bushing projection at both ends of the bushing. If the measurement is not 0.067 inch (1.7 mm), add or remove shims between the long driver and base as required.
12. Use the gauge and pin to check the spacing of the link halves.

Section Drawing and Integral Valves
NOTE: The steering control valve housing (7) Fig. 2 has internally two anti-cavitation valves (EE) and one check valve (CC). Before removing these valves, verify their positions.
17. To disassemble these valves, insert soda straws (3) in each end of the threaded holes, refer to Figure 3. Remove the steering control valve housing from the vise and tilt it until the port face (4) is upward. Continue turning until the roll pins (2) and ball checks (1) slide through the straws (3).

1. BALL CHECK 2. ROLL PIN 3. SODA STRAW 4. PORT FACE 5. ANTI-CAVITATION VALVES 6. CHECK VALVE
Inspection
1. Clean all parts in cleaning solvent and air dry on paper towels. Do not use cloths to wipe parts dry, as it may leave lint on the parts.
2. Check all machined surfaces for wear or damage. If there are rough places on the ends of the gerotor star or gerotor (4), steering control valve housing (7), end cap (2), or spacer plate (5), use 600 grit emery cloth to smooth the surfaces, refer to Figure 2. Place the emery cloth on a flat surface. If the emery cloth is new, rub a piece of steel across the emery cloth six times to remove the sharp pieces of grit. Make sure that the part is held flat on the emery cloth. Rub each part across the cloth six times. Check to see if the rough places are removed. Use this method until all rough places are removed. Clean the parts in cleaning solvent to remove any grit.
3. If the spool (9) and sleeve (8) or the bore in the housing of the steering control valve (7) is damaged or worn, use a new steering control valve.
4. Inspect the cap screws (1), pin (11), backup washer (15), seal ring (16), O-ring (17), needle thrust bearing (13) and bearing race (14). Use new parts as required.
5. If your steering control valve has anti-cavitation and check valves, inspect the balls checks (20), (23) and roll pins(21), (22) for damage or wear. Use new parts as required.
