Mower Deck Flat & V-Idler Pulley Combo for John Deere L118 G110 AUC20393 New
PRODUCT DESCRIPTION
Stop Deck Squeal & Belt Burn: Premium Flat & V-Idler Pulley Upgrade Combo
Eradicate severe mower deck vibrations, loud metallic squealing noises, and frequent, expensive belt failures. This Premium Aftermarket Mower Deck Idler Pulley Rebuild Set features both the Flat Idler Pulley (replaces GX20287) and the interlocking V-Groove Idler Pulley (replaces GX20286). Operating a riding mower over multiple cutting seasons subjects your lower deck pulleys to intense heat and dirt. This environment dries out the internal bearing tracks, leading to severe spindle wobble, belt slipping, and uneven cutting heights.
If your deck makes a loud roaring sound when you engage the PTO blades, your idlers are nearing total failure. Dropping this heavy-duty dual-pulley configuration onto your tensioner arms restores a whisper-quiet spin, perfectly stable belt tracking, and optimal rotational power delivery to your cutting spindles.
This premium, high-strength hardware kit is reverse-engineered to directly replace John Deere factory part numbers GX20287, AUC20393 (Flat) and GX20286, AUC20392 (V-Idler).
Why This Heavy-Duty Pulley Combo Kit is the Perfect Fix:
Complete Matching Tension Solution: Replaces both high-wear deck idler pulleys simultaneously to guarantee uniform tracking alignment and equalized belt pressure.
Premium Double-Sealed Bearings: Precision bearing tracks are packed with high-temperature synthetic grease and shielded with rubber seals to lock out pulverized grass flour and sand grit.
Heavy-Gauge Stamped Steel Construction: Riveted steel construction resists structural warping, rim chipping, and belt friction wear far better than fragile plastic composite alternatives.
Exact Dimensional OEM Matching: Stamped to precise factory dimensions ($11/16\\text{-inch}$ nominal inner bore diameter) to slide directly onto your existing John Deere shoulder bolts without loose play.
Technical Specifications:
Component Combination: 1x Flat Profile Idler + 1x V-Groove Profile Idler Spool
Flat Idler Dimensions: $11/16\\text{-inch}$ (17mm) Inner Bore x $3\\text{-}3/8\\text{-inch}$ Outer Diameter (Replaces GX20287 / AUC20393)

Condition: Brand New
Guaranteed Model Fitment Matrix:
Specifically dimensioned to slide onto the mower deck tension systems of the following John Deere riding mowers:
John Deere \"L\" Series Tractors: L100, L110, L111, L118, L120, L130 (Fits standard 42-inch and 48-inch cutting decks).

🛠️ Pro-Maintenance Tip: Watch the \"Belt Guard Pins!\" Installation Tip: When unbolting your old pulleys from the deck tensioner arms, pay close attention to the small metal belt guide pins or wire guards looping around the pulley rim. When installing the new GX20286 and GX20287 pulleys, ensure the deck belt sits completely inside these guide pins before tightening down the center locknut. If the belt is trapped on the outside of the guard wire, it will scrape against the raw metal pin, shredding your expensive drive belt within minutes of starting the blades. Washer Check: Always reuse the factory spacer washers underneath the pulley core to keep the bearing body from rubbing flat against the tensioner plate.
