Radiator cooling effect has a great influence.

The easier way to check the frame is to use the frame layout. The frame gauge is actually a set of observation pins. During the inspection, the frame gauge shall be hung from several different positions on the frame. When used, at least three gauges shall be used. The more gauges, the more accurate. If the frame is not deformed, the side view pin of each frame gauge should be aligned during inspection. If the observation pin fails to be aligned, the frame has been deformed as shown in the figure. The plate is sandwiched between tools to avoid deformation due to local force. If you do a precise inspection of the frame, you can use the plumb bob to draw the outline of the frame onto the floor. This operation must be very precise, the floor should be level and clean, if necessary, paste paper or nail on the floor, use the plumb in the car The measuring points on the rack project the ground, and then push the distance between the cars to measure the points on the ground. If the frame has been deformed, as long as the error is not large, it may still be corrected. The method of correction varies. Some regulations must be corrected in a cold state. The reason is that heating will weaken the frame. Some advocate the heating correction of the frame, but the temperature cannot exceed the dark red color at this time. Too high temperatures at this temperature will reduce the strength of the frame material and cause permanent damage. Especially for components that have undergone heat treatment, care must be taken. When heating, the heating area should be reduced as much as possible, and care should be taken in slow cooling. In order to avoid the material becomes brittle. The frame is usually heated with an oxygen-acetylene flame. Also need to use a number of straightening tools, such as the thick I-beam connecting the I-beam and the chain of the frame to correct the pressure of the chain Jack or screw special tools to correct the frame should be properly selected when the preload Parts. And in the frame and correction If the frame is severely deformed or broken, the frame needs to be replaced.
