The Genie 79640GT is a genuine OEM Extension Cylinder Wearpad designed for the TZ-34/20 trailer-mounted articulating boom lift. Sourced directly from Genie, this wearpad matches the original component specification — ensuring correct material grade, profile, and fitment without modification. Cross-reference part number 79640GT against your TZ-34/20 parts manual to confirm the correct position before ordering. As the machine accumulates hours, the wearpad protects the extension cylinder from metal-to-metal contact, and replacing it at the right interval keeps boom extension smooth and accurate.
Key Features
- Genuine OEM Material Grade — Manufactured to the same wear-resistant compound as the original, so the pad holds up under the lateral loads and repetitive cycling typical of trailer-mounted boom operation.
- Direct Replacement for the TZ-34/20 — Drops into the original cylinder housing position with no rework, maintaining the designed clearance and contact geometry of the boom's extension system.
- Correct Profile for Smooth Cylinder Travel — A properly fitted wearpad keeps the extension cylinder tracking true through its full stroke, preventing binding, uneven extension, and premature wear on surrounding components.
- Protects Higher-Cost Cylinder Components — By absorbing side-load friction, this low-cost wearpad shields the cylinder barrel and rod from scoring — avoiding far more expensive repairs down the line.
- Safety-Critical Fit for Aerial Operation — On an articulating boom lift, cylinder integrity directly affects platform positioning and stability. Using a correctly specified wearpad helps maintain the structural predictability the machine was engineered to deliver.
An extension cylinder wearpad is a low-friction wear element that sits between the cylinder body and its housing or boom section, keeping the cylinder aligned as it extends and retracts. Without it, metal surfaces make direct contact under load, causing scoring, increased operating resistance, and accelerated wear to the cylinder itself. When a wearpad becomes grooved, compressed, or cracked, boom extension can become uneven or jerky — a sign that replacement is overdue.
