Application and Buying Notes

Check the part number A0014997PGH and OEM number 4997PGH against the alternator already fitted to the machine before ordering. The key match points on this unit are 12V, 270A, pad mount, internal regulator, CW rotation and insulated return, so those details need to line up with the existing application.

The physical dimensions matter just as much as the electrical rating. Confirm the 190mm mount centre to centre, 126mm inside mounting legs, 80mm mount leg thickness, 12mm mount hole diameter and 22mm shaft diameter so the alternator sits correctly and the pulley and mounting arrangement are compatible with the machine.

This alternator includes remote sense and the note WL (D+) excite Battery Sense. If the original setup uses those connections, compare the wiring arrangement carefully before purchase. The unit is listed as above ground and supplied new, with a one year warranty and a weight of 14.58kg.

Fitment tokens supplied with this listing reference CLAAS and CLAAS JAGUAR, including CLAAS JAGUAR 2016. Even with that guidance, the safest check is still the physical part number and mounting measurements on the machine, because alternators can vary by build and electrical configuration.

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 A0014997PGH 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.
