The RYOBI 89037008003 is an OEM rear bevel trunnion designed as a direct factory replacement for compatible RYOBI and RIDGID table saw models. The trunnion assembly is a structural component of the saw's bevel mechanism, allowing the blade arbor to tilt accurately for angled cuts. When the original trunnion cracks, strips, or breaks, the blade cannot hold a consistent bevel angle, compromising cut accuracy. Replacing it with the correct OEM part restores proper blade tilt function and keeps the saw operating to factory specification. This part is intended for installation by experienced woodworkers or power tool service technicians familiar with table saw disassembly.
This rear bevel trunnion fits into the lower bevel adjustment system of the table saw, working in conjunction with the front trunnion and bevel lock to support and position the blade assembly during tilted cuts. It is typically found in contractor-style and jobsite table saws used in residential and light commercial woodworking applications. If the saw produces inconsistent bevel angles or the tilt mechanism feels loose or damaged, this component is a common point of failure to inspect and replace.
Designed as an OEM replacement trunnion for RYOBI and RIDGID table saw models that reference part number 89037008003. Verify fitment against your model's parts diagram before ordering.
Installation should be performed by a qualified technician or experienced operator familiar with table saw internal components. Disconnect the saw from its power source completely before beginning any disassembly. Replacing a trunnion typically requires removing the blade, throat plate, and table top to access the trunnion mounting hardware. After installation, verify blade squareness and bevel calibration before returning the saw to service.
