Full Description
7-1981 CV Ball Kit – 1310/1330 Series – 1.125" Ball – 0.5" Stud Bore – Greaseable
The 7-1981 is a greaseable CV ball kit for 1310 and 1330 series driveshaft applications. Ball diameter is 1.125", stud bore diameter is 0.5", seal height is 0.38", and seal OD is 1.45".
Specifications
- Part Number: 7-1981
- Series: 1310, 1330
- Ball Diameter: 1.125"
- Stud Bore Diameter: 0.5"
- Seal Height: 0.38"
- Seal OD: 1.45"
- Type: Greaseable
When fitting the 7-1981, verify the stud diameter is 0.5" to match the stud bore and the race pocket accepts a 1.125" ball. The greaseable design requires access to the grease fitting after installation — confirm there is clearance for a grease gun in the installed position. The 0.38" seal height and 1.45" seal OD must fit within the housing recess without interference.
The 7-1981 and 7-0081NG share the same ball diameter and stud bore but differ in seal height (0.38" vs 0.16"), seal OD (1.45" vs 1.34"), and grease provision. The larger seal dimensions on the 7-1981 require a housing recess that accommodates those measurements. Confirm housing recess depth and diameter before selecting between greaseable and non-grease variants.
