Application and Buying Notes

Before ordering, confirm the part number 110-555JHO, the 12V electrical system, and the 160A output match the machine or truck you are working on. Mounting details matter on alternators, so check the twin leg mount, 101mm inside mounting legs, and 216mm centre-to-centre measurement against the original unit.

The regulator is internal and the unit is self-exciting, which is relevant when replacing like for like equipment. The alternator is also listed with insulated return, clockwise rotation, and a 22mm shaft diameter, so those details should be compared carefully with the removed part or equipment specification before purchase.

If you are fitting into an industrial, transport, or heavy equipment application, use the application list as a guide only and still verify the actual machine configuration. Even within the same model family, alternator mounts and electrical arrangements can vary, so the safest check is the existing part number plus the physical measurements provided here.

The note against this alternator states it is temperature rated to 105deg. C and intended for J180 transport / industrial applications. That makes it important to confirm the duty cycle and operating environment on the vehicle or machine, especially where heat, load, and accessory equipment place extra demand on the charging system.

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 110-555JHO 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.

For part number 110-555JHO, 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 alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 160 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ATLAS COPCO ROC D7-RRC, ATLAS COPCO ROC D7-RRC 2018, BCI EXPLORER, CASE 9150, CASE IH, CASE IH 2044. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using the part number 110-555JHO, the 12V 160A specification, and the listed mounting and electrical details before ordering. Application references are provided as a guide and should be checked against the existing alternator and machine configuration.
