3-86-88S UDS 1410 Series Threaded Rubber Dust Cap for 1.375x16 Slip Yoke
The 3-86-88S is a UDS threaded rubber dust cap for 1410 series slip yokes with a 1.375" diameter by 16 threads per inch (1.375x16) threaded bore. This cap threads onto the cap seat at the splined bore end of the 1410 series slip yoke to protect the splines and transmission output shaft from road contamination and lubricant loss. The 1.375x16 thread spec is distinct to the 1410 series and must be verified before ordering.
Specifications
- Part Number: 3-86-88S
- Brand: UDS
- Series: 1410
- Cap Type: Threaded Rubber Dust Cap
- Thread Spec: 1.375" x 16 TPI
When fitting the 3-86-88S, verify the slip yoke bore thread diameter measures 1.375" and the thread pitch is 16 TPI. The 1410 series uses a smaller thread diameter than the 1610 (2.000x16) and 1710 (2.500x16) series. Do not confuse the 3-86-88S with caps for the 1350 series — while 1350 and 1410 share similar U-joint cap dimensions, the slip yoke thread specs may differ. Measure the existing cap seat before ordering.
The 3-86-88S replaces worn, split, or missing rubber dust caps on 1410 series slip yokes. Threaded rubber caps prevent ingestion of debris between the yoke bore and the transmission output shaft splines, which can cause spline wear and yoke scoring. Replace the 3-86-88S whenever the cap shows visible deterioration, has lost thread grip, or is missing entirely. Confirm U-joint series as 1410 and thread size as 1.375x16 before ordering.
