Your gearbox gives you the benefit of use for many years but after a while some problems are bound to occur. Gearbox repairs can be pretty expensive and hence it is better to check out any unusual sounds or vibrations indicating a gearbox problem.
Listed below are some indicative signs of problems beginning to occur in any of the Greaves
Gearboxes.
Low levels of Fluids
One of the major causes of automatic gearbox slippage or non-operation is insufficient transmission fluid in the system. Low levels of this fluid results in decreased temperature control and overheating occurs with the consequence the transmission fluid loses its viscosity. This produces major gearbox slippage. Replacement of transmission fluid bi-annually is essential to ensure the use of quality lubricants.
Dirty Gearbox Filter
A filter screen device which is provided in a gearbox helps to keep the gearbox body clean. This is done by trapping all foreign remains and metal shavings and preventing them from entering the passages and channels in the gearbox valve body. The lubricating oil has to be checked for the colour and smell. A dirty oil turns yellow and burnt lubricating fluid gives an acrid smell. The user can be immediately alerted to the gearbox problem.
Leaks
All authorised distributors of Greaves gearboxes warn users to look for leaks in their gearbox as that can prevent the occurrence of bigger problems. Such leaks can be found at various spots such as at the gearbox’s linkage connection, at the drain plug of gearbox, at the cable or speed sensor. Occurrence of leaks cannot be ruled out at the gearbox tail shaft’s end if the seals of the output or input gearbox shaft have worn out.
Clutches and Bands
All multiple gearboxes have clutches and bands inside, which engage each gear starting from the first to the higher gears. Worn out clutch material or weak bands can lead to non-function of some gears.
Gearbox Shift Linkage
Gearbox shift linkage comprises of rods and levers that change the various drive positions. If the linkage levers are bent or disconnected then they will prevent the shift selector from selecting the correct gear. It is essential to inspect the linkage connections at spots where they connect the gearbox levers.
Other Problems
Sometimes there are loud noises emanating from the gearbox or a continuous buzzing sound is heard. Clanging and clunking noises can come as transmission automatically shifts gear. A hard or delayed experience can be obtained during the change of gears or that the gears do not remain in gear.
Studies conducted in this context reveal that almost 25% of gearbox problems are caused due to lubrication and contamination issues.
Most of the gearbox problems can be resolved easily without spending too much money. It has to be seen, however, that in case of any problem you approach the authorised dealers of Premium Gearboxes or authorised dealers of Greaves Gearboxes.There are many gearbox dealers in Mumbai who can attend to your gearbox problems but it is always wise to visit the authorised people in this context.
