7/41 Differential Gear Assembly for Isuzu NPR

This Isuzu NPR differential gear assembly is offered with a 7/41 gear-tooth configuration. Match the product to the axle and the components needed for the repair.

For a seven-tooth pinion and 41-tooth crown wheel, the calculated reduction ratio is approximately 5.857:1. Specify the assembly scope and compare the splines, mounting arrangement and gear dimensions.

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 7/41 differential gear assembly for the Isuzu NPR is built around a seven-tooth pinion and a forty-one-tooth crown wheel, a pairing that works out to a calculated reduction ratio of approximately 5.857:1. Drive from the propeller shaft meets the pinion, crosses to the crown wheel and reaches the side gears that divide it between the two axle shafts, which are free to rotate at unequal speeds whenever the truck corners. The scope of the assembly forms part of the specification on this page: the enquiry states the components the repair needs, and the delivered assembly is matched to that scope rather than to a fixed catalogue definition.

• Component: differential gear assembly for the Isuzu NPR
• Gear tooth combination: 7/41 — a seven-tooth pinion with a forty-one-tooth crown wheel
• Calculated reduction ratio: approximately 5.857:1
• Enquiry variable: assembly scope, stated together with the axle identification

The 7/41 differential gear assembly matches Isuzu NPR trucks whose recorded final-drive figures are the seven-and-forty-one pairing, and an NPR keeps that record in more than one place. The axle identification plate, the build documentation delivered with the truck and the stamping on the original gear set all state the combination, and a count of seven pinion teeth and forty-one crown-wheel teeth on the removed assembly settles any remaining doubt. Alongside the ratio, the splines, the mounting arrangement and the gear dimensions are compared between the old unit and the ordered one, and the assembly scope is stated so the repair receives exactly the components it calls for.

• Ratio sources: axle identification plate, build documentation, stamping on the original gears
• Confirmation method: count seven pinion teeth and forty-one crown-wheel teeth on the removed set
• Interfaces to compare: splines, mounting arrangement, gear dimensions
• Scope to state: the components the repair needs from the assembly

Each 7/41 differential gear assembly for the Isuzu NPR is inspected by TOSEN before dispatch, verifying the seven-tooth pinion and the forty-one-tooth crown wheel against the calculated 5.857:1 figure and checking the splines, the mounting arrangement and the gear dimensions against the enquiry. The assembly scope is confirmed in the same step, so the components listed in the order are the components in the box. Where the customer supplies the ratio source from the truck records, the inspection ties the counted teeth to that source, closing the loop between the vehicle, the order and the shipment.

What is the 7/41 differential gear assembly for the Isuzu NPR?

The 7/41 differential gear assembly for the Isuzu NPR is a final-drive assembly specified by its gear-tooth pairing: seven teeth on the pinion and forty-one on the crown wheel, giving a calculated reduction ratio of approximately 5.857:1. The assembly multiplies the torque reaching the rear wheels and lets them rotate at different speeds through corners. Its scope, meaning the components included, is settled with TOSEN at enquiry stage to match the repair.

How is the 7/41 ratio confirmed from an NPR’s records?

Read the figures from the axle identification plate or the build documentation delivered with the truck, or from the stamping on the original gear set, and where those sources are missing, count the teeth on the removed assembly: seven on the pinion and forty-one on the crown wheel confirm the combination. Supplying the source used, together with the count, lets TOSEN tie the inspection record to the vehicle’s own identification before the order ships.

What does assembly scope mean on this page?

Assembly scope describes which components the supplied assembly includes, and the planned repair decides what that level should be. An axle that keeps its carrier needs a different supply than one being rebuilt from the housing out, so the enquiry states the scope together with the axle identification. Matching the scope to the work keeps the workshop from adapting the job around whatever arrives.

What should an NPR gear assembly enquiry contain?

State the vehicle and axle identification, the ratio source and the counted teeth, the assembly scope for the planned repair, and the splines, mounting arrangement and gear dimensions of the original unit, with the quantity and destination. TOSEN verifies those details against the inspected assembly before dispatch, so the 7/41 pairing and the scope both arrive as ordered.
