Nikko Starter Motor 24V 11 Tooth CW 7.5KW NXS620

This Nikko starter motor is a new 24V unit with 11 teeth, clockwise rotation, and a 7.5kW power rating. It is listed under part number NXS620 and OEM number 0-23000-7742, with a 3 hole starter mount and a 100mm flange diameter.

Key dimensions include mount centres A 146mm, B 122mm, and C 132mm, plus a 13mm mount hole diameter, 400mm overall length, 46mm pinion diameter, and 51mm pinion at rest. Those measurements matter when comparing against the existing starter on the machine, especially where mounting pattern and clearance are tight.

The unit suits Hitachi EX1200 with S6R engine, and the fitment preview also references Hitachi EX1200-5, Hitachi EX1200-5C, and several Mitsubishi Industrial applications. Because starter motors are a direct match item, it is best checked against the part number, tooth count, rotation, voltage, and mounting measurements before ordering.

Application and Buying Notes

For a starter motor, the safest check is to match the electrical and mounting details exactly. This unit is 24V, clockwise rotation, 11 tooth, and 7.5kW, so those points should line up with the original starter or the machine specification before purchase.

The mounting pattern is specific: 3 hole mount with centres A 146mm, B 122mm, and C 132mm, plus a 100mm flange diameter and 13mm mount holes. If any of those measurements differ from the removed unit, the starter may not align correctly even if the engine family looks similar.

The listed application for this part is Hitachi EX1200 with S6R engine, with additional fitment references shown for Hitachi EX1200-5, Hitachi EX1200-5C, and selected Mitsubishi Industrial engines. Because heavy equipment can vary by build and component changes, the part number NXS620 and OEM number 0-23000-7742 should be checked against the existing unit or parts catalogue.

Weight, overall length, pinion diameter, and pinion at rest are also useful when confirming physical clearance around the bell housing and mounting area. This starter is 400mm long, has a 46mm pinion diameter, a 51mm pinion at rest, and weighs 17kg, which are practical details when comparing against the old starter during replacement planning.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number NXS620 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Additional published details for cross-checking include Starter Mount Type 3 Hole, OEM Number 0-23000-7742, Product Group 2 STARTER MOTORS, Part No. NXS620, Brand NIKKO, Description Nikko Starter Motor 24V 11Th CW, Flange Diameter 100mm, Mount Centres B 122mm, Mount Hole Diameter 13.

Nikko Starter Motor 24V 11Th CW. Part number NXS620 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number NXS620, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HITACHI EX1200-5, HITACHI EX1200-5 2000, HITACHI EX1200-5 2001, HITACHI EX1200-5 2002, MITSUBISHI INDUSTRIAL S16R, MITSUBISHI INDUSTRIAL S16R 1999. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by matching part number NXS620 or OEM number 0-23000-7742, then verify 24V, 11 tooth, clockwise rotation, and the mounting dimensions against the original starter and application details before ordering.
