Swapping the Windshield on a Classic Kenworth W900A (1961-1994)
If you drive a Kenworth W900A built between 1961 and 1994, you are sitting behind the wheel of a real workhorse. I've spent years turning wrenches and pulling glass on these classic rigs. When that iconic split windshield takes a rock on the highway, you can't just call a rookie to fix it. These older trucks don't use the modern glue-in glass you see on cars today. They rely on heavy-duty rubber gaskets and a locking bead, which takes a specific touch to get right.
Why the W900A Glass Needs an Experienced Hand
The 1961-1994 W900A uses a flat, two-piece windshield setup. Sourcing the exact cut of heavy-duty safety glass is just the first step. The real challenge is dealing with the aging cab frame. After decades of hauling loads across Canada, the metal around that glass has seen a lot of salt, snow, and rough roads.
The Hidden Enemy: Pinch Weld Rust
Before we even think about seating the new glass, we strip out the old weatherstripping and inspect the pinch weld. In our Canadian climate, rust likes to hide right under that rubber gasket. If you don't clean up that channel and treat the bare metal, your new windshield will leak the second you hit a heavy rainstorm.
What We Look For During Removal
- Hardened rubber gaskets: Old seals get brittle and crack, making them impossible to reuse. We always recommend running a fresh gasket on these older Kenworths.
- Frame rot: We clean out the track completely to make sure the new rubber sits flush against solid metal.
- Locking strip tension: The bead that locks the glass into the gasket has to be seated perfectly, or the glass will rattle loose on bumpy job sites.
Getting the Fit Right the First Time
Wrestling a flat pane of glass into a thick rubber gasket takes patience and the right specialized hook tools. We use a soapy water slip method to guide the glass into the channel without stretching or tearing the new rubber. Once it sits flat, we run the locking bead in tight. No shortcuts, just solid mechanical work.
