Application and Buying Notes

When replacing a starter motor, the most reliable checks are the part number BXM159E, the 12V rating, the 12-tooth pinion, and the clockwise rotation. Those details need to line up with the vehicle application and the existing starter, because starters can look similar while differing in tooth count, rotation, mount pattern, or pinion dimensions.

The mounting details matter here as much as the electrical rating. This Bosch unit has a 3-hole starter mount, mount centres of 98mm, 83mm, and 22mm, a 68mm flange diameter, and 10mm mount holes. It also measures 191mm overall, with a 32mm pinion diameter and 30mm pinion at rest, so these dimensions should be checked carefully against the removed unit.

A 1.2kW starter is a specific application choice rather than a universal one, and the dry clutch note should be respected when comparing parts. If you are working on a Holden application, confirm the exact vehicle details and inspect the existing starter before purchase, especially where model years, engine combinations, or previous repairs may have altered the original fitment.

The one-year warranty applies to this new Bosch starter motor, but warranty cover does not replace the need to confirm compatibility before fitment. If the vehicle has had a starter changed previously, the safest approach is to compare the current unit to BXM159E and verify the mount centres, tooth count, and rotation before installation.

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 BXM159E 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 Wet / Dry Clutch Dry, Product Group 2 STARTER MOTORS, Part No. BXM159E, Brand BOSCH, Description Bosch Starter Motor 12V 12Th CW, Flange Diameter 68mm, Mount Centres B 83mm, Mount Hole Diameter 10, Overall Length 191mm.

Bosch Starter Motor 12V 12Th CW. Part number BXM159E should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number BXM159E, 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 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN CALAIS, HOLDEN CALAIS 2006, HOLDEN CALAIS 2007, HOLDEN CALAIS 2008. 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 Bosch part number BXM159E, 12V specification, 12-tooth CW rotation, and the listed mounting and pinion dimensions against the vehicle and the existing starter motor before ordering.
