<\/span><\/h2>\nSome spindle housings accept individual bearings and seals; others are serviced as assemblies. The correct decision depends on housing bore condition, shaft wear, pulley fit, deck damage, parts availability, labor, and required press tools. Do not hammer a bearing through a casting or press through the rolling elements.<\/p>\n
When replacing bearings, support the correct race, control depth and orientation, and install seals without cutting the lip. When replacing the assembly, verify shaft length, blade mount, bolt pattern, pulley offset, grease fitting, rotation, and hardware grade by model and serial number.<\/p>\n
A bearing that failed soon after replacement may have been damaged during pressing, run with incorrect belt tension, received incompatible grease, operated with a bent blade, or sat in a distorted deck. Finding that cause protects the new part.<\/p>\n

Use the frequency, grease, quantity, and access method specified for your own mower; sealed spindles may not have grease fittings.<\/p>\n
