Section ausiliari

Slipout in the auxiliary section may be caused by the clutching teeth being worn, pointu, o micca cumplettamente prumessa. These conditions cause the clutch gear to “walk” out of engagement as the gears turn.

Causes of these types of clutching defects are clashing or normal wear after long life. Vibrations set up by an improperly aligned driveline and low air pressure add to the slipout problem.

Jumpout in the auxiliary section usually occurs with the splitter gear set. If torque is not sufficiently broken during splitter shifts, the sliding clutch gear may not have enough time to complete the shift before torque is reapplied to the gears. As turcenti hè reapplied, the partially engaged clutch gear “jumps” out of the splitter gear. Since the gears have torque applied to them, damage will be done to the clutching teeth of the mating gears.

The effort required to move a gear shift lever from one gear position to another varies. If too great an effort is required it will be a constant cause of complaint from the driver.

Most lagnanza sò cun ligami chiú tipu luntani usatu in vehicule cabover-mutore. Before checking the transmission for hard shifting the remote linkage should be inspected. Linkage problems stem from worn connections or bushings, lià, improper adjustment, lack of lubrication on the joints or an obstruction which restricts free movement. À definisce se la trasmissioni stessa hè a causa di shifting dura, caccià u to feel passata, o lingua da u cima di a trasmissioni. Allora, move the shift blocks into each gear position using a pry bar or screwdriver. If the yoke bars slide easily, u priculu hè cù l 'assemblea lingua. If the trouble is in the transmission, it will generally be caused by one of the following:

Sè shifting dura č solu in prima è riversu, the shift block detent plunger movement may be restricted. This can result from burrs on the plunger, or from overtightening the plunger spring plug. With the plunger blocked in the depressed position, the plug should be tightened until it bottoms out against the spring, tandu sò sustinuti fora 1/4 à 1/2 turnu.
Material clashing ùn deve esse cunfusu cu shifting dura. Gear clashing occurs when an attempt is made to engage the clutch gear before it has reached synchronization with the mainshaft gear.

Prigiuneru

The transmission operating temperature should never exceed 250°F (120° C) per un piriudu imparu di tempu. Sè si faci, the oil will breakdown and shorten transmission life.

A causa di l 'attritu di parti muvimenti, transmissions will produce a certain amount of heat. In most cases normal operating temperature is approximately 100°F (40° C) above ambient. Heat is dissipated through the transmission case. When conditions prevent the proper dissipation of heat, then overheating occurs.
Nanzu à cuntrollà di pussibili causi di overheating, the oil temperature gauge and sending unit should be inspected to make sure they are giving correct readings.

Causes of Overheating

Noise trasmissioni

There will always be a certain level of noise due to the normal transmission operation. Tuttavia, excessive noise or unusual noise such as a whine, growl, or squeal indicates some kind of a problem.

The transmission itself can be the cause of excessive or unusual noise. Also, noise can originate elsewhere in the vehicle, Ma esse chjappi è Chjami Aghjalesi da u trasmissioni.

  • Lava - mmistuti, o zucchetta u denti vigori. Such bumps or swells can be removed with a hone or small hand grinder; these areas can be identified as highly polished pots on the face of the gear tooth. giniralmenti, this noise is more prominent when the gear is loaded; cusì, the problem gear can be located as the noise occurs in a specific gear position. Bumps or swells are caused by improper handling of gears before or during assembly.
  • spilli – Noise comes in at low shaft speeds in any position. It is caused by bearings with damaged balls or rollers, or with pitted and spalled raceways.
cracked transmission gears
  • longue durée Matos – A gear cracked or broken by shock loading or by pressing on shaft during installation will produce this sound at low speeds. At altu ùn mettite un ulula sarà prisente.

  • Spilli - spilli "Pinched", having insufficient axial or radial clearance

3. ringhiosi

  • Timing Error – Improper timing of the transmission during reassembly, or improper timing due to gear turning on the countershaft. Both conditions produce an error in tooth spacing.
