The IHI to Kato rebranding transitioned IHI excavator models to Kato equivalents starting in the early 2010s, with serial number prefixes changing from "IS" to "KA" (e.g., IHI IS50UX becomes Kato K107-2). Use old IHI serials by cross-referencing models via prefix swaps and S/N ranges—AFT Parts stocks OEM-spec undercarriage components like track rollers, carrier rollers, and idlers for seamless fits across Canada with 12-month warranty and free ground shipping to most provinces.

What Was the IHI to Kato Rebranding and Merger?
IHI's excavator division rebranded to Kato around 2010–2012 under corporate restructuring, retaining core designs for mini and mid-size machines used in Canadian construction, forestry, and mining. Legacy IHI machines (e.g., IS-series) are now serviced as Kato equivalents, affecting parts catalogs and ordering processes for contractors in Alberta oil sands operations, Ontario sites, and across provinces. This transition reflects IHI's strategic shift; the company consolidated its heavy equipment portfolio while Kato absorbed the product line. For B2B buyers, the rebranding means older IHI units remain fully serviceable—undercarriage components are cross-compatible through proper serial-to-model translation. AFT Parts simplifies this by stocking OEM-spec parts compatible with both legacy IHI and modern Kato designs, covering 20+ machine brands for Canada-wide fleets.
Why Do IHI to Kato Serial Number Changes Cause Parts Confusion?
Serial number shifts from "IS" prefixes to "KA" prefixes, combined with S/N range breaks (e.g., IHI up to 20,000 → Kato 30,000+), create ordering errors when sourcing undercarriage components like sprockets, carrier rollers, and idlers. Repair shops in British Columbia and Quebec often face downtime from mismatched parts; rental firms risk high OEM lead times and costs for legacy IHI units. The confusion stems from incomplete cross-reference guides in older catalogs. AFT Parts provides expert support via email and WhatsApp, ensuring accurate IHI to Kato undercarriage parts matching with 12-month pro-rated warranty coverage, eliminating guesswork and reducing downtime for Canadian operators.

| IHI IS60U (S/N <15,000) | Kato K108 (KA prefix) | Track Shoe, Repair Link Kit | Verified OEM-spec fit |

| IHI IS45UX (S/N <22,000) | Kato K90-2 (KA prefix) | Idler, Sprocket, Rubber Pads | Verified OEM-spec fit |
How Can You Use Old IHI Serial Numbers for Kato Parts Lookup?
Step 1: Locate the IHI identification plate on your machine and note the prefix (IS) and serial number range. Step 2: Cross-reference the serial range against official IHI–Kato conversion tables to identify the Kato model equivalent (e.g., IS50UX → K107-2). Step 3: Use AFT Parts' 20+ brand database to verify exact undercarriage component fits for your machine. Step 4: Contact AFT support via WhatsApp (+1 236–965–6529) or email (support@aft-parts.com) to confirm fitment on track rollers, idlers, or rubber tracks before ordering. This process eliminates cross-ordering errors and ensures OEM-spec compatibility across your fleet.
Which Undercarriage Parts Are Most Affected by IHI to Kato Changes?
Track rollers (bottom rollers supporting machine weight) are the most affected, followed by carrier rollers (top rollers guiding track chains), idlers (front idlers maintaining track tension), and sprockets (drive sprockets engaging track links). Repair link kits and rubber tracks also require accurate serial cross-reference. AFT Parts stocks OEM-spec versions of all these components, compatible with both legacy IHI and modern Kato designs, with CAD pricing ranging from $143 (carrier rollers) to $999.99 (rubber tracks). All items ship with 12-month pro-rated warranty and free ground shipping to Newfoundland, Nova Scotia, Saskatchewan, and all other Canadian provinces. For mining fleets bundling repair link kits and bolts, savings can reach 25–50% compared to OEM pricing.

AFT Parts Expert Views
"For IHI IS55UX to Kato K107-3 transitions, prioritize double-flange track rollers and carrier rollers—our OEM-spec versions cut wear by up to 30% in demanding Quebec aggregate and Ontario construction environments. Many operators overlook the carrier roller upgrade, resulting in premature track sagging and chain misalignment. We've completed successful fleet transitions for Alberta oil-sand operators and Saskatchewan mining firms. The key is verifying serial ranges early and bundling complementary parts—idlers and sprockets wear together, so replacing them as a set eliminates future downtime. Our 12-month pro-rated warranty covers all transition scenarios, and we offer same-day quotes across Canadian provinces. For repair shops and rental companies managing mixed IHI–Kato fleets, our franchise dealer program provides exclusive margins and direct access to our technical team.
