T34 Servicing Schedule
INSPECTION OF THE TANK AFTER EVERY 10 - 12 HOURS TRAVEL OR AFTER COVERING 250-300 KM
INSPECTION OF THE TANK AFTER EVERY 25 - 30 HOURS TRAVEL OR AFTER COVERING 500-600 KM
(IN ADDITION TO INSPECTION AFTER 10-12 HOURS)
INSPECTION OF THE TANK AFTER EVERY 50 HOURS TRAVEL OR AFTER COVERING 1000 KM
(IN ADDITION TO INSPECTION AFTER 25-30 HOURS)
- After every 10 hours of engine running it is necessary to examine and clean the mesh filter in the distributor cock.
- After every 25 hours of engine running it is necessary to clean the fuel filter.
- After every 50 hours of engine running, the fuel tank drain plugs should be unscrewed and sediment removed.
- If any defects occur in the fuel injector pump, the fuel feed pump and the fuel injector pump should be detached and handed over to a base workshop or to a special fitter.
- The air cleaner should be periodically cleaned. The period depends on the terrain and time of the year. In summer when the atmosphere is dust laden, the air cleaners should be cleaned and oiled after 10 hours of engine running. In the winter only after 20-25 engine running hours. The air cleaners should be cleaned with kerosine.
- After 500 km. disconnect the tracks, remove the cap of the sprocket wheel and test the assembly locking spindles (#2) for looseness. If necessary tighten up the nuts and slacken off 1/16 of a turn and re-fit with split pin.
- After 1000 km. 1 kg of lubricant should be inserted through the opening in the cover of the casing and 2.5 kg into the greasing aperture. The lubricant should be 70% "Avia" oil and 30% "Konstalin".
- Maintenance of the Suspension - Track Adjustment This is carried out in the following way :- The locking bolt of the axis of the crank is unscrewed to 12 to 15 mm. The nut is turned until the teeth of the crank and the bracket are no longer meshing. The unscrewing of the locks and nuts is carried out from the driving compartment. The nut is unscrewed by a special spanner.
- Maintenance of the starter
1. Inspect the commutator and brushes once a month.
2. After every 50 working hours, remove the front cap of the starting relay and examine the contacts. - Lubrication
Every 12-15 engine working hours the lubricator at the side of the control should be filled with 15 to 20 drops of "Avia" oil and, having removed the cap of the bearing at the side of the commutator, pack the bearing with grease (Konstalin or Solidol). - Lubricate every hour of engine running: Water Pump Spindle (1 location point)
- Lubricate after completion of 100 Km:
- Shaft of steering clutch control levers (4 location points)
- Pedal shafts of engine clutch & foot brake (2 location points)
- Hinge pins connecting the engine clutch pedal and foot break with front tie rod (2 location points)
- Compensating shaft (7 location points)
- Shaft of hand control to fuel injection pump (1 location point)
INSPECTION OF THE TANK AFTER EVERY 10 - 12 HOURS TRAVEL OR AFTER COVERING 250-300 KM
- Fuel Distributor cock Inspect and clean the mesh filter of the fuel distributor cock. To clean the filter unscrew the plug in the body of the cock and remove filter. Clean the filter in "gasoil" or petrol and afterwards blow out with air.
- Oil and water radiators (and after travel through dust in summer) Inspect and when necessary clean the cooling surfaces from oil and dust. When possible it is recommended to clean the grooves of the radiators with compressed air.
- Air cleaner (in summer) Remove, take down, clean and replace. Remove the cover of the air cleaner in one piece with its sections and wire-wool, clean the wire-wool in kerosine, place the cover and wire-wool in an oil bath so that the wire-wool absorbs the oil, remove is and allow the superfluous oil to drip off. Change the oil in the air cleaner oil bath.
- Engine Clutch Test the engagement of the clutch and tightness of the control linkage. The travel of the presser plate should be 6-7 mm. If the travel of the presser plate is less than 6 mm the adjustment described in Chapter III should be carried out.
INSPECTION OF THE TANK AFTER EVERY 25 - 30 HOURS TRAVEL OR AFTER COVERING 500-600 KM
(IN ADDITION TO INSPECTION AFTER 10-12 HOURS)
- Engine fuel and oil systems Inspect the oil and fuel leads. The hoses should be without cracks, twists, or kinks.
- Engine fuel injection pump Inspect the fixture of the fuel injection pump on the crankcase.
- Filters of the drain plugs of the oil tanks Inspect and clean the mesh filters of the radiator tanks Clean with "Gasoil"
- Air cleaner (winter) Remove, take down, clean and replace. Remove the cover of the air cleaner in one piece with its sections and wire-wool, clean the wire-wool in kerosine, place the cover and wire-wool in an oil bath so that the wire-wool absorbs the oil, remove is and allow the superfluous oil to drip off. Change the oil in the air cleaner oil bath.
- Tachometer and speedometer cables Inspect the attachment of the ends of the cables and the cable themselves.
- Engine fuel filter Remove, take down, clean and replace according to instructions issued for maintenance of the engine lubrication system.
- Oil filter Remove, take down, clean and replace according to instructions issued for maintenance of the engine lubrication system.
- Engine clutch Check that the flywheel is seated firmly on the crankshaft. For this test the fan must be gripped by hand and rocked to and fro. There should be no play.
INSPECTION OF THE TANK AFTER EVERY 50 HOURS TRAVEL OR AFTER COVERING 1000 KM
(IN ADDITION TO INSPECTION AFTER 25-30 HOURS)
- Final Drive Check the assembly locking spindles of the driven gear (by adjusting the conical bearing). If the play (looseness) of the assembly locking spindles is more than 0.15 mm, tighten the nut accordingly. Then slacken the nut 1/6 of a turn and fix split pin. To test the tightness of the assembly locking spindles it is necessary to disconnect the track and remove the sprocket wheel cap.
- Assembly locking spindles of suspension arms. Check the tension of assembly locking spindles of the suspension arm. It is necessary to unscrew the cap on the ends of the suspension shaft (on one side of the tank). Tighten the nuts of the assembly locking spindles as required then slacken off 3/4 of a turn. For the suspension arms of four bogies it is necessary to tighten the nuts of the assembly locking spindle on both sides and slacken off 1/2 a turn.
- Engine suspension Test the tension of the nuts securing the engine to the engine chassis. The nuts must be firmly tightened and fitted with split pins.
