Work the belt over the upper drive pulley into the pulley groove. 4. Squeeze the belt enough to remove the wood block. With the block removed, release the tension on the belt. 5. Reinstall the spare belt carrier and the drive belt guard. 6. Replace the spare belt before the next trowel use. See spare drive belt replacement procedures.
HHN 34TVD — MAINTENANCE 5 4 6 2 1 1 2 3 4 5 6 3 CV Joint Bolt (Remove 3 places) New Spare Drive Belt Bolt, Spare Drive Belt Carrier Spare Drive Belt Holder Left Side Gearbox Figure 22. Spare Drive Belt Replacement The HHN 34TVD trowel is equipped with a "Torque Converter" which supplies torque to both the left and right gear boxes. The function of the a torque converter is to automatically deliver the correct amount of torque required by the trowel under all load conditions.
HHN 34TVD — MAINTENANCE As shown in Figure 24, centrifugal force pushes the roller arms (see Figure 25 below) against the ramp plate, forcing moveable face toward fixed face squeezing belt. 1 2 3 4 5 6 10 1 7 4 9 Drive Pulley Ramp Plate Weight Roller Arm Spring Bushing Figure 26.
HHN 34TVD — MAINTENANCE Clutch Blade Pitch This clutch system provides a high pulley ratio (a low gear- so to speak) to start out and a low pulley ratio ( a high gear- so to speak) for a high speed operation, with infinite variation between the two. Sometimes it may be necessary to match blade pitch between the two sets of blades. There are some signs that this may be necessary. For example, the differences in pitch could cause a noticeable difference in finish quality between the two sets of blades.
HHN 34TVD — MAINTENANCE Blade Pitch Adjustment Procedure Maintenance adjustment of blade pitch is made by adjusting a bolt (Figure 30) on the arm of the trowel blade finger. This bolt is the contact point of the trowel arm to the lower wear plate on the thrust collar. The goal of adjustment is to promote consistent blade pitch and finishing quality. Look for the following indications if blades are wearing unevenly. If so, adjustment may be necessary.
HHN 34TVD — MAINTENANCE Trowel Arm Adjustment Use the following procedure to check and adjust trowel arms, and check for worn or damaged components when it becomes apparent that the trowel is finishing poorly or in need of routine maintenance. Look for the following indications. Trowel arm alignment, worn spider bushings or bent trowel arms may the cause.
HHN 34TVD— MAINTENANCE 2. Loosen the jam nut and cone point square head set screw. 3. Carefully lift the upper trowel assembly off of the spider assembly. A slight tap with a rubber mallet may be necessary to dislodge the spider from the main shaft of the gearbox. 2. Each trowel arm is held in place at the spider plate by a hex head bolt (zerk grease fitting) and a roll pin. Remove both the hex head bolt and the roll pin (Figure 36) from the spider plate. 3. Remove the trowel arm from the spider plate.
HHN 34TVD— MAINTENANCE Checking Trowel Arm Straightness Trowel arms can be damaged by rough handling, (such as dropping the trowel on the pad), or by striking exposed plumbing, forms, or rebar while in operation. A bent trowel arm will not allow the trowel to operate in a smooth fluid rotation. If bent trowel arms are suspect, check for flatness as follows, refer to Figures 38 and 39: 3.
HHN 34TVD— MAINTENANCE 4. Use an allen wrench to tighten the locking bolts securing the trowel arm in place. 5. Adjust the bolt "distance" shown in Figure 42 to match one of the arms. The other arms will be adjusted to match this distance. 6. Loosen the locking nut on the trowel arm lever, then turn the trowel arm adjusting bolt until it barely touches (.010") the fixture adjusting bolt. 7. Once the correct adjustment is made, tighten the lock nut on the trowel arm to lock in place. 8.
HHN 34TVD— MAINTENANCE Installing Pans Onto Finisher Blades These round discs sometimes referred to as "pans" attach to the spiders arms and allow early floating on wet concrete and easy movement from wet to dry areas. They are also very effective in embedding large aggregates and surface hardeners. 1. Lift trowel just enough to slide pan under blades. Lower finisher onto pan with blades (item #1) adjacent to Z-Clips (item #4). 2. Rotate blades into position under Z-Clips.
HHN 34TVD — TROUBLESHOOTING TABLE 5. TROUBLESHOOTING SYMPTOM Engine running rough or not at all. Safety Stop Switch not functioning. If trowel “bounces, rolls concrete, or makes uneven swirls in concrete”. POSSIBLE PROBLEM SOLUTION Safety Stop Switch malfunction? Make sure that the Safety Stop Switch is functioning when the operator is seated; replace switch if necessary. Fuel? Look at the fuel system. Make sure there is fuel being supplied to the engine.
HHN 34TVD — TROUBLESHOOTING TABLE 5. TROUBLESHOOTING (CONTINUED) SYMPTOM Lights (optional) not working. Retardant spray (optional) not working. POSSIBLE PROBLEM Wiring? Check all electrical connections, including the master on/off switch and check to see if wiring is in good condition with no shor ts. Replace as necessary. Lights? Check to see if light bulbs are still good. Replace if broken. Retardant? Check the tank to make sure retardant is present. Fill tank as necessary.
