Why Shop VI Equipment for Your Excavator Idler Assemblies

There are many reasons to choose VI Equipment for your excavator idler assemblies. We offer exceptional value, unmatched selection, and reliable performance to keep your projects on track. Discover the VI Equipment difference and experience the benefits firsthand.

Excavator Idler Assemblies: Guiding Every Track, Every Shift

Idler assemblies sit at the very front (or rear, on some machines) of your excavator’s undercarriage and keep the track chain perfectly aligned as it rolls around the sprocket and bottom rollers. A healthy idler absorbs shock loads during turns, maintains correct track tension, and prevents side-loading that can chew through links, bushings, and sprocket teeth. At VI Equipment we stock a deep range of heavy-duty idler assemblies—complete with shell, shaft, bushing, seals, and yokes—so you can swap, tension, and get back to digging without the costly drift and derailments that happen when a worn idler is left in service.

OEM-Matched & High-Spec Aftermarket Idlers for John Deere, Hitachi & Caterpillar

Whether you’re running a Deere 35G on residential trenches, a Hitachi ZX250 on roadwork, or a Cat 336 loading overburden, we have the idler assemblies engineered for your exact frame width and carrier roller spacing. Our rebuilt program reclaims OEM housings, fits them with induction-hardened rims, and presses in chrome-moly shafts—giving you factory performance at about 60 % of new-dealer cost. Prefer brand-new? Our premium aftermarket line is forged from 45Mn2 alloy steel, fully sealed, and pressure-lubed for long life in abrasive, wet, or freezing conditions. Every assembly is catalogued by part number and serial range, so matching takes minutes, not hours.

Spotting Idler Wear and Choosing the Right Replacement

If you’re seeing shiny flats on the idler rim, cracked side flanges, or excessive carrier roller scalloping, it’s time to act. Measure rim diameter with a caliper and compare to your service manual; a loss of more than 10 % of original diameter usually signals replacement. You’ll also want to check shaft wobble—any movement over 0.25 mm accelerates seal failure and grease loss. Our parts desk can walk you through cross-referencing your machine’s model, frame serial, and track shoe size to ensure the new idler assembly preserves correct chain pitch and tensioning range, keeping liner and roller wear to a minimum.

In-House Idler Rebuilds: Hard-Faced Rims & Precision Bushings

For fleets aiming to extend component life and lower carbon footprint, our Langley cylinder shop also handles idler rebuilds. We laser-clad worn rims with chromium-carbide hard-facing, line-bore pilot holes to OEM spec, and press in C86300 manganese-bronze bushings for superior galling resistance. New multi-lip grease seals complete the package. Each assembly is spun under load and thermal-cycled before leaving the bench, then serialized so future service history is traceable. Customers typically gain an extra 2,000–3,000 operating hours—roughly a 40 % life extension compared to run-to-failure replacement cycles.

Same-Day Shipping Across Canada & Emergency Support 24/7

Downtime drains profit, so every idler assembly in our yard is palletized, shrink-wrapped, and ready to ship within two hours of your purchase order. Standard freight reaches Alberta and Saskatchewan sites in 48 hours and Ontario quarries in 72 hours, while Lower Mainland contractors can pick up curbside the same day. If a breakdown hits after hours, our emergency hotline connects you directly to a parts specialist who can quote, dispatch, and provide install torque specs on the spot—because track failures don’t respect nine-to-five schedules.
