Tennant/Nobles - 4039789 - Wheel, 03.0D 0.88W 0.50B (Replaces Tennant 222066)

Tennant 4039789 is a genuine Tennant wheel, 3.0 in (76 mm) in outside diameter and 0.88 in (22.4 mm) wide, with a 0.50 in (12.7 mm) bore. It is also listed as 222066.

On the 5680 and 5700 walk-behind scrubbers it runs in the squeegee assembly, four per squeegee, in assembly 4016216 for the 700 mm squeegee and 4016214 for the 800 mm. The same wheel is listed on the 7200 rear squeegee (900 mm), in the 8300 main brush skirt group, and on several T500, T600 and A500 machines, so the count per machine varies. For the 5680, Tennant's manual says to check squeegee leveling and blade deflection daily or when you change floor types; correct deflection is 0.50 in (12 mm) on smooth floors and 0.62 in (15 mm) on rough floors.
