The Honda 90370-VG5-L00 Jam Nut (5/8"-18) is a genuine OEM fastener designed for CD7136 and CD7148 commercial mowers. As a direct Honda OEM component, it meets the exact thread specification — 5/8"-18 — called out in Honda's parts catalog for these machines. Honda supersedes parts at serial breaks, so confirm your mower's serial number against the fitment table before ordering to ensure this is the correct listing for your unit.
Key Features
- Genuine OEM Thread Specification — sourced directly from Honda, this jam nut carries the correct 5/8"-18 thread pitch required by the CD7136 and CD7148 commercial mowers.
- Direct OEM Replacement — replaces the original Honda part number 90370-VG5-L00 with no alterations needed to install.
- Serial Number Verification Recommended — Honda updates fastener specs at production breaks; check your serial number against the compatibility table to confirm this listing applies to your mower.
A jam nut is a thin locking nut threaded against a primary nut or along a threaded shaft to prevent loosening under vibration and operational loads. On commercial mowers like the CD7136 and CD7148, properly secured fasteners are essential for maintaining adjustment positions and keeping assemblies from backing off during use. A missing or damaged jam nut of the wrong thread pitch can allow critical adjustments to shift, affecting the performance and consistency of the mower.
