Standard U-Joint Cover Kit for 4.095" to 4.187" Drive Shaft O.D.

For all heavy truck part numbers:

Step 1. Measure mounting surface diameter using deep-jaw calipers, a diameter tape measure (Stanley p/n 33-115 works well) or measure the circumference and divide by Pi (3.1417).

Step 2. Select the corresponding packet of 4 mounting-pads, the interchangeable pads are numbered to match the driveline diameters covered in the kit. Example: 4590PD fits 4.590” diameter.

Step 3. Affix the 4 mounting pads over the 2 attachment bars in each of the cover halves.

Step 4. Place the cover halves over the drive line, rotate as needed to accommodate balancing weights. A zip-tie is included to hold the cover in place (cut it off & discard once screws are tightened).

Step 5. Using a 4mm hex (Allen) driver, tighten the 12ea. M5 x 0.8 captive socket head screws. There is no need to overtighten, snug the fasteners as you would on any other lightweight cover.

* When installed properly, the cover will not move on the mounting surface. Using reasonable force on the open bell, if movement is visible at the mount area, switch-out 2 opposing pads (for balance) to the next smaller diameter.

To access grease fittings facing driveshaft with cover in-place

Step 1. Looking into the open end of the cover, visually align and mark a spot above and in-line with the zerk, on the sloping section of the cover.

Step 2. Using a 15.75mm or 5/8” diameter drill bit on slow speed, drill an access hole on the marked spot.

Step 3. Place the provided 5/8” diameter plug(s) into the access hole(s) in the cover.
