Q 1. Does this alternator replace Bosch USA AL9936X?

A. Yes. The WAI 8050N carries a verified cross-reference to Bosch USA AL9936X, making it a direct replacement for that unit. It also covers Caterpillar 0R3653, 6P1395, 6T1395, 7T2095 and OR3653; Prestolite 110-285 and Prestolite Electric 110285; Motorola 10-285, 10-313, 10285, 110-313, 110313, 8HC3022F, 8HC3022FS, 8HC3025F; Halliburton 0106000047 and 010600047; DRI 572106354; and Sachin 68098639 — 20 OE references in total. Match your existing part number against this list before ordering, or search our cross-referenced catalogue by OEM number to confirm compatibility.

Q 2. Which Caterpillar part numbers does the WAI 8050N cross-reference to?

A. Five Caterpillar OE references are listed for this alternator: 0R3653, 6P1395, 6T1395, 7T2095, and OR3653. If your machine currently carries any of those numbers, the WAI 8050N is the confirmed replacement. Use the selection widget or search our catalogue by OEM number, and our Fit Guarantee covers every verified cross-reference shown.

Q 3. What are the key electrical specs of this alternator?

A. The WAI 8050N operates on a 24-volt system and delivers 35 amperes output. It follows the Motorola / Prestolite 8HC Series IR/EF design (internal regulator, external field) and features bi-directional rotation, so it suits applications regardless of which way the belt drives the pulley. It is supplied brand new.

Q 4. What does IR/EF mean on this alternator?

A. IR/EF stands for Internal Regulator / External Field. The voltage regulator is built into the alternator body (IR), while the field winding is energised by an external circuit (EF). This is the standard configuration for the Motorola / Prestolite 8HC Series and determines the wiring connections required during installation. Confirm your machine's wiring matches this configuration before fitting.

Q 5. Is this a new alternator or a remanufactured exchange unit?

A. The WAI 8050N is brand new — not remanufactured and not supplied on an exchange-core basis. Every unit is built to the original Motorola / Prestolite 8HC Series specification from new components.

Q 6. Is this part covered by your Fit Guarantee?

A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.

Q 7. Can I ask questions about this product before ordering?

A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
