Review on Gates 348489 Steering Pump Kit by Joshua Days

The big difference is that it comes with a regular metric 6203RS bearing with two rubber seals instead of a high temperature bearing with power steering fluid resistant seals. . The kit comes with an original NSK 6203DUL8A bearing, where DU is a modified dual lip seal; L - Gasket material - polyacrylic elastomer (maximum service temperature is 150°C vs. 120°C for rubber); 8A - ? . All o-rings were chocolate brown Viton rubber (very good quality) as OEM except the thinner of the two large diameter o-rings used to seal the end plate on the pulley side - it was black rubber e.g. B. Nitrile or EPDM, which may not withstand Mopar power steering fluids.
