Made this topic to help others in replacing oil seals in a 633 family of transaxles since most are no longer available.
Format will be SEAL Original Part# Known compatible replacement Found referenced unsure Size for cross-reference
Input Oil Seal: 6270H National 471466 NAPA 6903 0.25" wide x 1.124" OD x 0.625" Shaft Diameter
Brake Oil Seal: 6271H National 470954 NAPA7440 0.25" Wide x 1.25" OD 0.75" Shaft Diameter
Axle Oil Seals: 7392R 7393R (newer is double lipped) NAPA 9838; 9876 National 472311 0.25" Wide x 1.441" OD 1.0" Shaft Diameter
Hi/Lo Oil Seal: 6269H 532006269 SKF Part 4909 NAPA 4909 0.170" Wide x 0.688" OD x 0.50" Shaft Diameter
Older Roper 633a's found in Sears Suburban/Roper called for 5qts SAE30 NON-Detergent oil. Newer AYP/Electrolux found in Craftsman GT's call For 4qts SAE30 NON-Detergent oil.
**I have read the reason for NON-Detergent was to save on the oil seals. Especially on older tractors. Detergent oil was found to break down the seals.
