Drivers use the tape as a marker for the steering wheel. A couple examples for the use are as follows: When checking for the alignment after a wreck or damage, they line up the tape and check for drifting to ensure the car still drives straight. If the steering wheel ever comes off(wreck, relief driver, etc) they use the tape to determine where it goes back. Some use it as a marker for how far to turn the wheel into a turn. Watching a few NASCAR races will also help answer your question
AnswerIt also helps in pit stops to make sure the driver keep the front wheels straight. The wheel openings on speedway cars are made as small as possible for areodynamic reasons that the tires won't come off quickly for a good pit stop.To go a little deeper in the previous answer, as far as handling issues. A driver can use that as a gauge, if the car starts pushing, he can tell how much it changed by how much farther he has to turn the wheel. And after a wreck, if the tape isn't centered when the car is going straight, he knows that the front end alignment has been affected. Then by passing that info on to the crew chief, along with how the car is now handling, they can make a plan of action for the next pit stop on what to do to fix the car.
push on the tab in the little hole on the back of the steering wheel @ 6 oclock then push the center of the steering wheel up towards 12 oclock you may need to tap it but it will slide up.
It used to be at 2 o'clock and 10 o'clock but with the air bags in the steering wheel they now recommend 3'oclock and 12 o'clock. It's 3 o'clock and 9 o'clock.
The first thing on the list is to check your air pressure and have the alignment checked.
7 oclock position behind the crankshaft pulley
if you mean when installing a timing chain, the keyway or square notch should be at 12 oclock and the mark should be at 3 oclock
on the distributor @ 2 oclock
The LONG end of the petcock valve is the indicator of the positioning of the valve. 6'oclock is MAIN 3'oclock is OFF 12'oclock is RESERVE
i Have wheel and tire off caliper is visible. Caliper is at 9 OCLOCK TO 11 OCLOCK. Only nut visible on back side of 9 OCLOCK position. How do I remove pads? Phil K
Ball joints only really need to replaced when they are going bad. Usually you can tell if you put one hand on the 12 oclock position and the other on the 6 oclock position and try to wiggle the the tire. If it wiggles this way then ball joints are going bad. (Jack the vehicle up first). If you put one hand on the 3 oclock and the other in the 9 oclock position and wiggle it and it moves then the tie rods are going bad. If the whole tire moves in and out then the bearings are usually going bad. Hope this helps.
The crank gear should be in the 12: oclock position & the cam gear should be in the 6: oclock position facing each other this is top dead center on compression stroke.
No 1 cylinder is in the 5 : oclock position - 18436572 clock wise.
3 oclock
