bantu Bagéan
Slipout in the auxiliary section may be caused by the clutching teeth being worn, tapered, atanapi henteu pinuh aktipitas. 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. Salaku torsi ieu 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.
teuas shifting
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.
Paling keluhan nu mibanda beungkeut tipe jauh dipaké dina kandaraan cabover-mesin. Before checking the transmission for hard shifting the remote linkage should be inspected. Linkage problems stem from worn connections or bushings, mengikat, improper adjustment, lack of lubrication on the joints or an obstruction which restricts free movement. Pikeun nangtukeun lamun pangiriman sorangan anu ngabalukarkeun shifting teuas, nyabut uas shift atawa beungkeut ti luhur midiyeum. Satuluyna, move the shift blocks into each gear position using a pry bar or screwdriver. If the yoke bars slide easily, gangguan kasebut jeung assembly beungkeut. If the trouble is in the transmission, it will generally be caused by one of the following:
- Splines of sliding clutch gear binding on mainshaft as a result of a twisted mainshaft key, bent shift yoke or bowed mainshaft key.
- Yoke bar ngariung di bar perumahan salaku hasil tina perumahan retak, leuwih-torqued block shift lockscrew, sprung yoke bar, or swelled areas of the yoke bar.
Mun shifting teuas lumangsung ngan dina munggaran tur sabalikna, 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, lajeng dijieun kaluar 1/4 ka 1/2 giliran.
Gear clashing teu matak bingung jeung shifting teuas. Gear clashing occurs when an attempt is made to engage the clutch gear before it has reached synchronization with the mainshaft gear.
panas
The transmission operating temperature should never exceed 250°F (120° C) pikeun hiji jaman nambahan waktu. Mun hancana, the oil will breakdown and shorten transmission life.
Kusabab tina gesekan bagian pindah, 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.
Sateuacan ngecék mungkin nyababkeun overheating, the oil temperature gauge and sending unit should be inspected to make sure they are giving correct readings.
Causes of Overheating
1. lubrication bener. Tingkat minyak teuing low atawa teuing tinggi, wrong type of oil, or an operating angle of more than 12 derajat.
2. Operasi konsistén dina 20 mph.
3. Luhur mesin rpm.
4. aliran hawa diwatesan sabudeureun transmisi, due to the transmission being “boxed in” by frame rails, deck lids, tanghi bahan bakar jeung kurung ningkatna, or by a large bumper assembly.
5. Sistim knalpot deukeut teuing ka transmisi.
6. hawa ambient tinggi.
7. horsepower tinggi, operasi overdrive.
8. Coasting Turun gunung jeung clutch depresi.
Dina sababaraha kasus, an external oil cooler kit can be used to correct overheating problems.

transmisi Noise
There will always be a certain level of noise due to the normal transmission operation. Sanajan, excessive noise or unusual noise such as a whine, ngagerem, or squeal indicates some kind of a problem.
The transmission itself can be the cause of excessive or unusual noise. oge, noise can originate elsewhere in the vehicle, tapi jadi ngajemput na amplified ku midiyeum.
1. Knocking atanapi Thudding
- Gears - nabrak atanapi swells on huntu gear. 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. dina umumna, this noise is more prominent when the gear is loaded; sahingga, 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.
- arah – 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.
- retak Gear – A gear cracked or broken by shock loading or by pressing on shaft during installation will produce this sound at low speeds. Di speeds tinggi babaung a bakal hadir.
2. High Pitched Whine or Squeal
- Gear ngagem - hasil tina maké gear normal, including gear tooth pitting from excessive use. In advanced deterioration, lolong bakal hasil.
- Mismatched Gear Sets – Such gear sets are identified by an uneven wear pattern on the face of gear teeth.
- Arah - "Pinched" arah, having insufficient axial or radial clearance
3. Growling
- 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.
Causes of Transmission Noise Originating Elsewhere in Vehicle:
- Kasar engine idling. (tingali meletok gear)
- noise operasi Engine.
- Clutch driven plates in which the dampening action of springs or rubber blocks has been eliminated by wear set or fracture.
- Driveline kaluar tina kasaimbangan.
- sudut gabungan kerja Unequal.
