6×40 Differential Assembly for Mitsubishi Fuso PS100

This Fuso PS100 differential assembly is offered in a 6×40 gear-tooth configuration. Match the assembly to the truck's rear axle as well as the specified gear combination.

A six-tooth pinion and 40-tooth crown wheel give a calculated reduction ratio of approximately 6.667:1. The axle-shaft splines, input flange and housing dimensions are also needed for selection.

Send the vehicle and axle identification, crown-wheel and pinion tooth counts, spline details and quantity. Include the flange and housing dimensions for the assembly required.

The 6×40 differential assembly for the Mitsubishi Fuso PS100 is defined by its gear-tooth combination: a six-tooth pinion driving a forty-tooth crown wheel, which yields a calculated final-drive reduction of approximately 6.667:1. The figures mean the propeller shaft turns about 6.667 times for each full revolution of the crown wheel, exchanging propeller speed for wheel torque across a wide margin. A reduction this deep multiplies the engine’s torque heavily by the time it reaches the axle shafts, and the side gears inside the assembly still let the rear wheels rotate at different speeds when the truck turns.

• Component: differential assembly for the Mitsubishi Fuso PS100
• Gear tooth combination: 6×40 — six pinion teeth, forty crown-wheel teeth
• Calculated reduction ratio: approximately 6.667:1
• Warranty coverage: 12 months, as entered on the specification table

The 6×40 differential assembly suits Mitsubishi Fuso PS100 trucks whose original gears carry the six-and-forty tooth combination, and the pairing has to be confirmed from the vehicle rather than assumed from the model name. The confirmation comes from the original unit: counting the six teeth on the pinion and the forty on the crown wheel of the assembly being replaced settles the question directly, and reading the figures from the axle identification serves the same purpose when the old unit is still installed. The axle-shaft splines, the input flange and the housing dimensions complete the match, and together with the tooth counts they let TOSEN verify that a deep-ratio 6.667:1 unit is what the truck needs.

• Primary match: the 6×40 tooth combination, confirmed on the original assembly
• Ratio check: forty divided by six, approximately 6.667:1
• Interfaces to compare: axle-shaft splines, input flange, housing dimensions
• Caution: confirm the combination before ordering, never assume it from the model name

The 6×40 differential assembly for the Mitsubishi Fuso PS100 is supplied new, inspected tooth by tooth and covered by the 12 months warranty entered on the specification table. Every unit is checked before dispatch, with the pinion counted to six teeth and the crown wheel to forty, and the axle-shaft splines, the input flange and the housing dimensions verified against the enquiry in the same pass. Buyers who need the evidence for their records can request the inspection photographs with the quotation, which document the counted teeth and the checked interfaces before shipping.

What is the 6×40 differential assembly for the Mitsubishi Fuso PS100?

The 6×40 differential assembly for the Mitsubishi Fuso PS100 is a final-drive unit whose pinion carries six teeth and whose crown wheel carries forty, producing a calculated reduction ratio of approximately 6.667:1. The assembly multiplies torque strongly on its way to the rear axle shafts and lets the two rear wheels roll at unequal speeds through corners. The unit is supplied new with 12 months of warranty coverage and matched to the PS100 axle identification in the enquiry.

What does a 6×40 tooth combination mean in practice?

Six and forty are the tooth counts of the pinion and the crown wheel, and their quotient is the final-drive ratio of approximately 6.667:1, meaning the propeller shaft completes about 6.667 revolutions for each turn of the crown wheel and the rear wheels. The assembly converts propeller speed into a large amount of wheel torque, which is the work a heavy-ratio final drive performs in a truck axle. Confirming the counts on the removed unit verifies that this is the ratio the truck was built with.

How do I confirm that my PS100 needs the 6×40 assembly?

Confirm from the original assembly before ordering: count the pinion teeth and the crown-wheel teeth on the unit being replaced, or read the figures from the axle identification, and check that the result is six and forty. Then compare the axle-shaft splines, the input flange and the housing dimensions with the assembly offered here. Sending the counts and the measurements with the enquiry lets TOSEN verify the 6×40 match before dispatch.

How long is the warranty on the 6×40 differential assembly?

The assembly is covered for 12 months, the period entered on the specification table of this page. The coverage is supported by TOSEN’s pre-dispatch inspection, in which the pinion and crown-wheel teeth are counted against the 6×40 specification and the interfaces are checked against the enquiry. Keeping the quotation and the inspection record with the vehicle file completes the documentation the warranty expects.
