Q 1. What does this alternator fit — and does it replace my original Hitachi unit?

A. This WAI 14863N is confirmed to fit Case compact excavators, including the Case CX75 (2008–2013) and Case CX75SR (2004–2009) — 2 Case applications in total. It is a direct replacement for Hitachi original-equipment alternators referenced as LR150-714, LR150-714N, LR150-715, LR150714, LR150714N, and LR150715. Use the selection widget to match your machine by model and engine, search our cross-referenced catalogue by OEM number, or ask Simon to confirm fitment. Every fitment shown is backed by our Fit Guarantee.

Q 2. Does this replace Isuzu or JCB original alternator numbers?

A. Yes. The WAI 14863N crosses to Isuzu references 8972012810, 8972283180, and 8972283181, as well as JCB references 714-40090 and 71440090. In total there are 18 OE and aftermarket cross-references for this part, including references from AD Kuhner, BTS Turbo, Farcom, and Sando. Search our catalogue by any of these numbers to verify the match, or ask Simon if you need help cross-referencing your original part.

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

A. The WAI 14863N is a 12-volt, 50-amp alternator built to Hitachi IR/IF (internal regulator, internally fused) design. The output pulley is a groove-type pulley, matching the original drive belt engagement. It is supplied brand new.

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

A. IR/IF stands for Internal Regulator, Internally Fused. It means the voltage regulator is housed within the alternator body rather than as a separate external component. This simplifies installation and keeps the electrical arrangement tidy, matching the original Hitachi design on the Case CX75 and CX75SR.

Q 5. How do I confirm this part fits my vehicle or machine?

A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.

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.
