Bus Body Building Guidelines
It is important to ensure that the body is fitted to the vehicle chassis in such a way that the load imposed is transmitted evenly. At the same time, the rigidly mounted
body must flex with the frame. Care should be taken to ensure that the body and the vehicle chassis are compatible. An example of bad selection would be a
construction in which a short body is made on a long wheel base. In this case, it becomes necessary to shorten the chassis rear overhang to accommodate the body. As
a result, the centre of gravity moves forward, and a load greater than what is desirable, is imposed on front axle.
It is also essential to give careful consideration to the movement or modification of the various parts of the vehicle. These include electrical wiring, electrical equipment,
brake connections, brake piping, frame modification like chassis extension and other chassis components - to ensure good performance in operation.
Apart from the above recommendations, you should always follow the tips given below, to get the best performance from your vehicle.
1. Keep body weight minimum by selecting proper design and materials. This will save fuel and increase tyre life.
2. Use curved window glass, avoid sharp corners and protruding destination boards, to reduce air resistance.
3. Ensure that body dimensions, seating space and gangway width comply with current government regulations.
4. Ensure ease of removal and assembly of various aggregates like gearbox, suspension, battery, spare wheel, etc. Also provide flaps/cut outs for servicing.
5. De-rust, phosphate and apply primer to the body skeleton before fixing panels.
6. Use zinc plated hardware of standard quality, for various body joints.
7. While carrying out structural work, protect instrument panel, steering wheel, driver's/co-driver's seats, brake fluid containers, hoses etc. from damage.
8. Do not drill or weld chassis frame or remove any rivet. Do not use chassis or leaf spring as the earthing point during welding.
9. Do not clamp bus body cross bearers to chassis cross member.
10. No body mountings should foul with any chassis aggregate or frame cross member.
11. Avoid practice of cutting chassis cross member for mounting of 'U'
bolts.
12. Do not extend chassis rear overhang. If required, contact us.
13. Avoid eccentric mounting of cross bearers.
14. Do not use balata packing more than 6 mm thick for cross bearer mounting. This will result in premature perishing and damage to the chassis long member. In case
thicker packing is required, use steel plates to compensate along with 6 mm balata packing.
15. Avoid ' U ' bolts touching the chassis long members. This should be done by using aluminum alloy packing between ' U ' bolt bottom radius and long member
bottom flange.
16. As far as possible, avoid post location over wheel arch.
17. Do not modify the front side of the cowl in a way that it would restrict the air flow to the radiator and air cleaner. Reducing the height/width of the centre flap or
closing the louvres provided on the cowl front face are to be avoided.
18. No restriction should be placed beneath the remote mounted air filter. Provide sufficient clearance for fitment and removal of the air cleaner.
19. The air intake hoses are not to be distributed during body building. However, if hoses are removed for any reason, cover the turbocharger and intake manifold
openings with suitable plastic caps to avoid foreign dust particles entry, till the time the hoses are connected back. The clamps should be properly tightened
during this operation.
20. The service indicator fitted on the air cleaner outlet pipe should not be tampered with, by way of painting etc.
21. Always close the mouth of the air intake to turbo charger when the air filter is removed during body building.
22. Do no reroute air intake, coolant and fuel lines.
23. Do not keep the radiator open so as to avoid contamination of coolant with dust and foreign material.
24. Disconnect battery and alternator connections before starting any electrical wielding on chassis/body.
