T hese ratings will provide approximately 3,000 hours operation at a speed of 2,000 RPM and at a 3o angle.
They presume uniform power transmission and proper maintenance.
2
T hese values are the maximum recommended for use in applications such as off-highway cycling operation.
If these values are exceeded, the standard mating components may be inadequate and the universal joint
life will be reduced.
3
T his size available either as a universal joint only or in combination with 9C driveshaft components.
4
This size available either as a universal joint only or in combination with 10C driveshaft components.

Operating Speed
A number of factors influence the maximum RPM at which a driveshaft can be operated. The major criteria are
as follows:
1. Overall length
2. Tube diameter
3. Universal joint angle
4. Mating component rigidity
The following Tables I, II, and III collectively define guidelines for the first three criteria.
Table I illustrates the maximum RPM normally allowed on the various universal joint sizes. The values are subject to the angle and speed limitations as defined in Tables II and Table III.
Table II defines the maximum allowable universal joint angle when operated at the specific RPM. These values
are based upon an angular acceleration of approximately 1,000 Rad/Sec.2. This has been found to be acceptable in most applications. The table assumes a two joint system with operating u-joint angles of Driver and
Driven shafts within 1o of each other.

Operating Speed (continued)
Table III relates the maximum shaft length to operating RPM
for the standard tube size. Be sure to consider any overspeed conditions.
Larger diameter tubing is available on certain universal
joint sizes to raise the operating RPM.
See Tables I and II for limiting factors on operating speeds

Mounting Capscrew Dimensional and Torque Data
To help insure universal joint retention, it is imperative that the correct capscrew be used and properly torqued. All must
be Grade 8 or equivalent quality. The torque settings apply only to clean, dry, non-coated bolts.

Mechanics® Driveshaft & Components
Universal Joint Installation and Lubrication
Universal Joint Installation
Ease of installation and service is one of the primary features of Mechanics® Universal Joints.
To assemble a joint to a yoke, insert the key and pilot of one bearing into the keyway and pilot of the yoke (Fig. 1). Next,
insert the key and pilot of the opposite bearing into the yoke. Since this is a precision product, the fit is intended to be
tight and some compression of the seals and/or thrust washers may be required to seat the second bearing. This can be
done with a ‘C’ clamp, a tap with a soft hammer (Fig. 2), or with hand pressure. DO NOT use the bolts to seat the bearings!
Once the bearings are properly seated, insert the bolts and uniformly torque them to the proper level as shown in “Mounting Capscrew Dimensional and Torque Data”. Use SAE Grade 8 or equivalent, non-coated bolts that are clean and dry.
Yoke faces, bearing mounting faces, circular pilots and keyways must be free of foreign material, burrs and nicks which
will prevent the asembly from becoming properly seated.
Lubrication
Grease Specifications:
- Universal Joints
-Relube: -Permanently-Lubed: -Driveshaft Slip Spline Lithium base grease without Molybdenum Disulfide Additive.
No relubrication required
Long life Lithium base grease with a Molybdenum Disulfide Additive.
Lubrication must be maintained in universal joints and slip assemblies for satisfactory operation. Since the driveshaft
is subject to many types of environments, it is important to maintain a lubriction interval which is appropriate to the
type of environment and vehicle use. A 250 hour interval, or longer, may be satisfactory for most off-highway conditions.
However, severe conditions may warrant more frequent lubrication.
Factory lubrication of relubricable slip assemblies provides an initial coat over both male and female parts. Additional
lubrication may be added through the fitting on the slip yoke. With the driveshaft in the fully compressed position, grease
should be added until excess appears at the vent hole of the dust cup or at the spline seal (Fig. 3).
If the driveshaft can not be fully compressed, care must be taken not to overfill the spline cavity or the driveshaft will not
compress when required. A universal joint is considered adequately lubricated only when all four bearings are purged
of air and old grease. Mechanics® patented seals allow all four bearings to bleed at the same pressure (Fig. 4) to insure
proper lubrication.

Fig. 3 – Grease appears from vent hole
Fig. 4 – Seals allow grease to bleed so lubricant can flow
through all trunnions.
