Clean all parts in a solvent tank and dry with compressed air prior to inspecting. Carefully inspect all critical areas for any surface finish abnormalities: Seal grooves, bearing grooves, thrust surfaces, rod surface, housing bore and gear teeth. Assembly 2. Inspect the thrust washers (304) for rough or worn edges and surfaces.
SECTION 4 - BOOM & PLATFORM 2. Install the thrust washer (304) onto shaft (2) and end cap (4). 4. Using a seal tool install the main pressure seal (205) onto shaft (2) and end cap (4). Use the seal tool in a circular motion. 3. Install the wiper seal (304.1/green 0-ring) into it’s groove on the shaft (2) and end cap (4) around the outside edge of the thrust washer (304). 5. Install the wear guide (302) on the end cap (4) and shaft (2). 6.
SECTION 4 - BOOM & PLATFORM Each T-seal has 2 back-up rings (see drawing for orientation). Beginning with the inner seal (200) insert one end of b/u ring in the lower groove and feed the rest in using a circular motion. Make sure the wedged ends overlap correctly. Repeat this step for the outer seal (202). 3121253 – JLG Lift – 7. Insert the piston (3) into the housing (1) as shown, until the outer piston seal (202) is touching inside the housing bore. 8.
SECTION 4 - BOOM & PLATFORM 9. Looking from the opposite end of the housing (1) you can see if your timing marks are lining up. When they do, tap the piston (3) in until the gear teeth mesh together. Tap the piston into the housing the rest of the way until it bottoms out. 11. Looking from the view shown, use the existing timing marks to line up the gear teeth on the shaft (2) with the gear teeth on the inside of the piston (3).
SECTION 4 - BOOM & PLATFORM 14. Coat the threads on the end of the shaft with antiseize grease to prevent galling. 17. Tighten the end cap (4). In most cases the original holes for the lock pins will line up. 15. Install the 0-ring (204) and back-up ring (207) into the inner seal groove on the end cap (4). 18. Place the lock pins (109) provided in the Helac seal kit in the holes with the dimple side up. Then, using a punch, tap the lock pins to the bottom of the hole. 16.

SECTION 7 - BASIC ELECTRICAL INFORMATION & SCHEMATICS SECTION 7. BASIC ELECTRICAL INFORMATION & SCHEMATICS 7.1 GENERAL Polarity This section contains basic electrical information and schematics to be used for locating and correcting most of the operating problems which may develop. If a problem should develop which is not presented in this section or which is not corrected by listed corrective actions, technically qualified guidance should be obtained before proceeding with any maintenance.
SECTION 7 - BASIC ELECTRICAL INFORMATION & SCHEMATICS Resistance Measurement Continuity Measurement Figure 7-3. Continuity Measurement • Some meters require a separate button press to enable audible continuity testing • Circuit power must be turned OFF before testing continuity Figure 7-2. Resistance Measurement • First test meter and leads by touching leads together.
SECTION 7 - BASIC ELECTRICAL INFORMATION & SCHEMATICS Current Measurement 7.3 APPLYING SILICONE DIELECTRIC COMPOUND TO ELECTRICAL CONNECTIONS NOTE: This section is not applicable for battery terminals. JLG P/N 0100048 DIELECTRIC GREASE (NOVAGARD G661) IS THE ONLY MATERIAL APPROVED FOR USE AS A DIELECTRIC GREASE. NOTE: Do NOT apply dielectric grease to the following connections: • Main Boom Rotary sensor connections (on Celesco Sensor), • LSS Modules connections, • Deutz EMR 2 ECM connection.
SECTION 7 - BASIC ELECTRICAL INFORMATION & SCHEMATICS 3. Anderson connectors for the battery boxes and battery chargers should have silicone grease applied to the contacts only. NOTE: Curing-type sealants might also be used to prevent shorting and would be less messy, but would make future pin removal more difficult. Deutsch HD, DT, DTM, DRC Series The Deutsch connector system is commonly used for harsh environment interconnect. Follow the installation instructions.
SECTION 7 - BASIC ELECTRICAL INFORMATION & SCHEMATICS DIN Connectors This connector is typically used on hydraulic valves. Follow the installation instructions. Figure 7-6. Use of Seal Plugs AMP Mate-N-Lok Follow the installation instructions. 3121253 Exclusions A limited number of connectors do not benefit from dielectric grease, or may be permanently damaged by application. Dielectric grease may not be required in properly sealed enclosures.
SECTION 7 - BASIC ELECTRICAL INFORMATION & SCHEMATICS BRAD HARRISON / PHOENIX CONTACT M12 AMP JUNIOR TIMER The connector uses gold contact material to resist corrosion and an o-ring seal for moisture integrity. If dielectric grease is mistakenly applied to this connector system, the low-force contacts cannot displace the grease to achieve electrical contact. Once contaminated, there is no practical way to remove the dielectric grease (replacement of female contacts required).
