Gear shift pattern

Double H shift pattern.

Rev,Crawler,1,2,3 & 4 Low range

After achieving the max speed at 4th gear driver should push the gear lever to his right side keeping gear lever in neutral position.

Then shift the gears

5,6,7 & 8 High range

Range selection procedure

Start the engine and keep in idle speed

Push the gear lever to the LH side and watch for the range indicator Glow

UPWRAD SHIFT

Depress the clutch fully

Select the LOW speed and engage

Release the clutch gradually.

Accelerate gradually

After attaining the normal speed depress the clutch and shift to I speed.

In the similar manner progressively shift up to IV speed.

Now bring the gear lever to neutral position and push to RH side with little more effort.

Now HIGH range is in selection with the Range indicator OFF

Range selection procedure.

Now shift to V speed ie to the I speed position.

Progressively shift up to VIII speed.

DOWNWARD SHIFT

To shift downward with reduced vehicle speed with application brake and depressing the clutch shift down to VII speed.

Progressively shift up to V speed

Now to change in to low range

Keep the gear lever in neutral and push towards LH side with little more effort.

Now the LOW range is in selection with indicator ON.

Depress the clutch and engage IV speed.

Now gradually shift down up to I speed

Note : Range selection should be done while driving the vehicle in IV & V speed only.

Load gear L and Reverse shall be engaged only in low range with vehicle at zero stop

Operating temperature

Operating temperature

It is important that the transmission operating temperature does not exceed 120C

for an extended period of time. Operating temperatures above 120 C cause

breakdown of the oil and shorten transmission life. The following conditions in any

combination can cause operating temperatures of over 120 C.

Operating consistently at road speeds under 32Km/h

High engine RPM

High ambient temperature

Restricted air flow around transmission

Exhaust to close to transmission

High horsepower, overdrive operation

High power PTO operation for extensive periods while stationary

High operating temperatures may require more frequent oil changes and/or

fitment of a cooler.
