Q 1. What does WAI 12130N replace — which original part numbers does it cross-reference?

A. The WAI 12130N replaces 14 original-equipment references in total. These include Delco Remy DRA0019, John Deere AT173624, RE501634, RE506196, RE506197, SE501823 and SE501835, Magneton 443 113 515 241, 9-515-241 and 9515.765, Pal Magnaton 9515170, 9515241 and 9515765, and Universal UNA2395. Use the selection widget or search our cross-referenced catalogue by OEM number to confirm fitment for your machine, or ask Simon — every reference shown is backed by our Fit Guarantee.

Q 2. Which John Deere and Grimmer Schmidt machines does this alternator fit?

A. Confirmed fitments include the John Deere 270 (1999–2004) and John Deere 280 (2002–2004) compact utility tractors, plus the Grimmer Schmidt 185DRE and Grimmer Schmidt 375DRA compressors — four applications in total. Use the selection widget to match your exact make, model and engine variant, or search the catalogue by OEM number. Fitment is backed by our Fit Guarantee.

Q 3. What are the key specifications of this alternator?

A. The 12130N is a brand-new 12V, 55A alternator of Magneton manufacture, IR/EF design (internal regulator, external fan), with clockwise rotation and a groove pulley. It is supplied new — not remanufactured.

Q 4. What does IR/EF mean on an alternator, and does this unit need a separate voltage regulator?

A. IR/EF stands for Internal Regulator, External Fan. The voltage regulator is built into the alternator body, so no separate external regulator is required. The external fan cools the unit during operation. This matches the original-equipment configuration on the listed John Deere and Grimmer Schmidt applications.

Q 5. Does the groove pulley on the 12130N match the original drive-belt setup?

A. Yes. The WAI 12130N is fitted with a groove pulley that matches the original drive-belt geometry on its confirmed applications. Combined with clockwise rotation, it is designed to install directly in place of the OE alternator without modification.

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.
