Hustler 608751 Black Dust Cap | OEM Front Caster Grease Cap

Hustler 608751 OEM Black Front Caster Grease Cap

The Hustler 608751 Black Dust Cap is a genuine OEM Hustler replacement cap used on select front caster wheel and bearing assemblies. This part is listed as DUST CAP, BLACK and is commonly searched as a front caster grease cap, caster dust cap, wheel bearing dust cap, or black caster cap.

The front caster grease cap helps cover and protect the caster wheel bearing area from dirt, grass, moisture, and debris. A missing, loose, cracked, or damaged dust cap can allow contamination into the bearing area and may lead to premature bearing wear, rough caster movement, wheel wobble, or front-end service issues.

Always verify your full Hustler model number, serial number, original dust cap part number, caster wheel assembly, bearing setup, cap size, and parts diagram before ordering. Do not order by mower series or deck size alone.
