This manual has been compiled in a simple, non-technical manner and every effort has been made to cover the most important items. It will provide a convenient reference source for the serviceman. Wherever possible, repetition of service instructions has been avoided by combining truck or unit models.
An index at the front of each group permits locating items covered in a particular Group. Where necessary, groups have been subdivided into sections. As additional data is compiled, new or revised pages will be issued. These should be inserted in their respective group and section.
IMPORTANT: Before starting any overhauling work, always remove the dirt that has accumulated around the parts to be disturbed. When parts are taken off, dirt not removed may fall into the units, contaminating the lubricating oil, and getting into bearings and other working parts. As dirt contains grit and abrasives, considerable unnecessary wear and reduction in efficiency is invariably the result.
INSPECTION OF NEW TRUCKS BEFORE DELIVERY
When trucks corne off the assembly line at the factory they have already been given numerous unit inspections and in addition are subjected to a driving test and final inspection. Districts and Dealers should, however, recheck each truck prior to delivery to a customer. This is particularly advisable if trucks have been driven through or "double decked" by a drive-away company.
It is the responsibility of each District and Dealer to see that new trucks are delivered to users in a fault-free condition. This will mean a satisfied owner and will tend to eliminate unnecessary trips to the Service Station for minor adjustments during the warranty period.
The pre-delivery service at each District must include all of the operations listed below:
- Clean and polish truck if necessary.
- Lubricate chassis, and check oil in air cleaner.
- Check lubricant level in transmission.
- Check lubricant level in differential.
- Check oil level in engine. Drain and refill if oil is not of proper viscosity for locality or season, or if truck has been driven any great distance.
- Check cooling system for water.
- Install battery, checking specific gravity and level of electrolyte.
- Warm up engine and check operation of instruments and lights.
- Tighten cylinder head and manifold nuts uniformly, using tension indicating wrench. (If truck has not been driven since leaving the factory, this operation is unnecessary.)
- Adjust valve lash if necessary. Note: If head is tightened in operation (9), valves in overhead-valve engines will require adjustment.
- Check and adjust carburetor for idle.
- Check tire alignment on wheels. Correct if necessary. Tighten rim lugs.
- all hub stud nuts.
- Check front wheel alignment for toe-in of wheels.
- Install tools, spare rim, and owner's manual, etc.
- Give truck short road test, checking brakes, controls, and general handling, to assure that all are functioning properly.
INSTRUCTIONS TO OWNER AT TIME OF DELIVERY OF NEW TRUCK
As a rule, the purchaser's first impression is a lasting one, therefore it can easily be understood that trucks should be in perfect mechanical condition at the time of delivery. The operation and care of the truck should be thoroughly explained to the owner at this time.
It is that the following instructions be given purchaser at the time of delivery of the truck:
- General information covering the construction and operation of the truck.
- Advice as to the proper grade of lubricating oil. (See Lubrication Section.)
- Explanation of the function, purpose, and maintenance of the oil filter.
- Explanation of the function, purpose, and maintenance of the air cleaner.
- Cover proper draining of the cooling system and the importance of using recommended anti-freeze solutions when necessary.
- Importance of proper clutch pedal clearance in prolonging clutch life.
- Cover lubrication of truck completely, point out hazard and costliness of neglect.
- Advise owner to register such units as batteries, electrical units, etc., with the local authorized dealers of that equipment.
- Point out advantages of bringing truck to the International Service Station at specified intervals during the warranty period of inspection, at which time there may possibly be some minor adjustments advisable. These, if made, will aid in prolonging the life of the truck.
- Stress the benefits of using only International Service parts and the advantages of having service work performed in International Service Stations or by International Dealers.
