LUBRICATION SPECIFICATIONS UNIVERSAL JOINTS J3299-2-DSSP JUNE 2008 Supersedes J3299-1-HVTSS Dated December 2007
LUBRICATION SPECIFICATIONS Don’t Neglect Spicer® Driveshaft Lubrication Lack of proper lubrication is the most common cause of premature failure of universal joint kits and slip assemblies. Properly sized Spicer U-joints that are adequately relubricated at recommended intervals will normally meet or exceed fleet operational requirements.
Warning - Rotating shafts can be dangerous. You can snag clothes, skin, hair, hands, etc. This can cause injury or death. Do not go under the vehicle when the engine is running. 10 Series Driveshaft - Full Round Closed Yoke Holes On 10 Series full round closed hole yokes, Figures B & C, loosen the bolts holding the bearing assembly that doesn’t purge to release seal tension. It may be necessary to loosen the bearing assembly approximately 1/16 inch minimum. Apply grease gun pressure to purge seal or seals.
SPL Series Driveshaft Apply grease gun pressure and purge all four bearings until fresh grease is seen at all four bearing seals. 1. If a bearing will not purge, apply pressure to yoke lug ear opposite of non-purging bearing while grease gun pressure is being applied. This should firmly seat the ujoint against the cup seal and relieve seal tension of nonpurging bearing. See Warning, below.
Chart 4 10 Series and SPL Universal Joints 1. Standard Application - Use a good quality E.P. (Extreme Pressure) grease (Timken Test Load 45 lbs. min.) meeting N.L.G.I (National Lubricating Grease Institute) grade 2 specification. Grease must have an operating range of +325°F/+163°C to -10°F/-23°C and be compatible with commonly used multipurpose greases such as Lithium Soap Types. 2.
Recommended Relube Cycles for Universal Joint Kits Relubrication cycles vary depending on the service requirements and operating conditions of the equipment. Chart 4 shows a recommended lube cycle for various types of service. Lubrication Procedure for 10 Series Slip Assemblies Relube slip assemblies at the same intervals as universal joint kits. Apply grease gun pressure until grease appears at the pressure relief hole in the slip yoke plug.
