They can be used to advance or retard the cam timing to correct inaccuracies in the cam or change the characteristics of the cam profile.
The make would help. Some used a timing chain and others used gear to gear. The distributor could be worn also.
PN offset stands for Pseudo-Noise offset. It is a method used in telecommunications to synchronize the timing of different devices within a communication system, particularly in CDMA (Code Division Multiple Access) systems. PN codes are sequences of binary digits that are used to establish this timing relationship. The PN offset is the specific value within the PN code sequence assigned to a device for synchronization.
An "idler" is typically used for tensioning of a belt, as in the timing belt, or a chain.
It measures the speed of the output gear of the transmission. It is used for shift timing.
NA used 16x7.5 w/45mm offset. TT used that in front, & 16x8.5 w/35mm offset in rear.
Bushings are used in suspension parts, mainly.
no. offset can be used as past tense as well.
On the injection pump gear are timing marks for 3,4 and 6 cylinder engines as the same gear is used in all the engines. To time the pump align the mark with the correct number for the engine with the center of the crank shaft and the center of the injection pump center. Timing should be 10 degrees before TDC on cylinder 1 The injection pump gear has 48 teeth with each tooth representing 7.73 degrees.
Belt drive is releatively new and in the old days it was mostly chain or gear wheel drive with wear and a lot of noise. Most commonly used for the timing of car valves and injection pump timing
When changing the timing belt on a Nissan Frontier, a specialty tool known as a gear puller is used. The puller can be borrowed with a deposit from most large chain auto parts.
Think of bushings as they really are: a consumable bearing. They don't move and are not as hard as bearings. They are composite material usually containing a lot of brass. They are present in the engine and the transmission.
Depends on the engine. 4 Cylinder GM engines used a pair of timing gears (no belt), while the V-6 used a gear and chain system. Neither one used a belt (other than the serpentine belt to drive the AC, alternator, power steering and water pumps.
