- Worn universal joints (Ne ji nîşanên transmission, di heman demê de nîşana vibration.)
Splines nanxwarina
Pin Synchronizer Broken
Input Spline Wear
Common causes of vibration include driveline imbalance or misalignment, wheels an çermikên şikand bêhevseng, engine asê running, heywanan engine şikestî an westiyam, û cemidandina westiyam,.
Gear Slipout û Jumpout
Beþ Front
Dema ku zilamê de, dişemite meşî ye ku bi mentiqekî bi gear mainshaft, diranên mating li hev bin. diranên clutching Tapered an westiyam, daxwaza "meşa" hewl bidin bêyî ku vitêsê cihê. Di bin şert û mercên mafê, slipout bi encam bibe. Hin ji van şert û mercên ne:
- Nifşek eccentrically bi pîlotê flywheel engine siyar.
- dikete gear Excessive ku têrbiryar diranên clutching.
- sererastkirinê yên xelet ji têkiliya kontrol guherîna ji dûr ve di encamê de bi pabendbûna bi qismî. Jî ji bo girêdana vekin û bushings westiyam, kontrol.
Teeth Clutching xeyidî
Gear clutching diranên wearing ji bo taper.
Detent Spring
zext e Têrê li ball detent ji biharê detent qels an şikandin.
Worn nîrê Bar
wear Excessive li ser asta detent ji bar nîrê
Şert û mercên ku dikare Jumpout Sedama
- Extra levers guherîna giran û dirêj ku deydîkê, fashion bêhêviyan, ji xebatê yên li ser vehewandina lawaz e. action kûrkirina ji lever bi ser dikeve detent tengezarî biharê.
- kontrola ji dûr ve mekanîk, bi axayê siwarî ji frame. tevgera Dengûbasên di navbera pakêta engine-belavkirin û frame dikarin ji nifşekî ji gear zorê. Westiyam, an jî heywanan engine şikestî zêdekirina bandora vê rewşa.
Beþ auxiliary
Slipout in the auxiliary section may be caused by the clutching teeth being worn, tapered, an bi çalakî ne. 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. Wek torque reapplied ye, 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.
GUHERTINA Hard
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.
Gelek gilî û bi hêztir bike type ji dûr ve hatine bikaranîn, di wesayîtên cabover-engine in. Before checking the transmission for hard shifting the remote linkage should be inspected. Linkage problems stem from worn connections or bushings, girêdidan, improper adjustment, lack of lubrication on the joints or an obstruction which restricts free movement. Ji bo destnîşankirina eger ji nifşekî bi xwe doza ji reel zehmet e, jê lever Shift an jî çênekin ji ser depika ser serê vitêsê. Paşan, move the shift blocks into each gear position using a pry bar or screwdriver. If the yoke bars slide easily, di tengahiyê de ye, bi meclîsa têkiliya. 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.
- darikên nîrê mulzem in xanî bar ya ku di encama xanî bibun, ser-torqued lockscrew block guherîna, sprung yoke bar, or swelled areas of the yoke bar.
Ger diguherîn zehmet tenê di yekem û berevajî diqewime, 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, piştre bi piştgirîya derve 1/4 ber 1/2 zîvir.
dikete Gear divê bi guherandina zehmet tevlihev ne. Gear clashing occurs when an attempt is made to engage the clutch gear before it has reached synchronization with the mainshaft gear.
Germa
The transmission operating temperature should never exceed 250°F (120° C) bo demeke dirêj ji dem. Ger ev, the oil will breakdown and shorten transmission life.
Ji ber yên ku pirsgirêkên ciddî yên parçeyên, 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.
Berî muayene ji bo sedemên ku yên pir, the oil temperature gauge and sending unit should be inspected to make sure they are giving correct readings.
Causes of Overheating
1. gêl de vediqetîne. asta petrolê kêm an jî zêde bilind, wrong type of oil, or an operating angle of more than 12 dereceyên.
2. Kar bi lehev bê bin 20 MPH.
3. RPM engine High.
4. herikîna hewa sînorkirin, li dora ji nifşekî, due to the transmission being “boxed in” by frame rails, deck lids, tankên sotemeniyê û bixemilînî bi heybet, or by a large bumper assembly.
5. sîstema Exhaust jî nêzî ji nifşekî.
6. germahîya ambient High.
7. bergîrî High, operasyona overdrive.
8. Coasting Downhill bi destê zilamê bînteng.
Di hin rewşan de, an external oil cooler kit can be used to correct overheating problems.

Noise nifşek
There will always be a certain level of noise due to the normal transmission operation. Lebê, excessive noise or unusual noise such as a whine, qûrqûrkirin, or squeal indicates some kind of a problem.
The transmission itself can be the cause of excessive or unusual noise. Jî, noise can originate elsewhere in the vehicle, lê bê hildan û bergirî ji aliyê vitêsê.
1. Li derî bixin an zingînî
- Gears - Untitled an çêrê li diranên 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. Giştîve, this noise is more prominent when the gear is loaded; ji ber vê yekê, 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.
- Dordîtinî – 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 Gear – A gear cracked or broken by shock loading or by pressing on shaft during installation will produce this sound at low speeds. Li qapat a hewarê wê amade bibe.
2. High Pitched Whine or Squeal
- Wear Gear - Di encama wear gear normal, including gear tooth pitting from excessive use. In advanced deterioration, a hewarê encama wê.
- Mismatched Gear Sets – Such gear sets are identified by an uneven wear pattern on the face of gear teeth.
- Bearings - bearings "tertikek", having insufficient axial or radial clearance
3. seyan
- 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:
- engine idling Rough. (dîtina ponij û gear)
- dengî xebatê Engine.
- Clutch driven plates in which the dampening action of springs or rubber blocks has been eliminated by wear set or fracture.
- Driveline ji balance.
- angles kar hevbeş ya newekhev.
