Woodward Spline Identification

SPLINE IDENTIFICATION: The diameter shown after the three-digit identifying code is the nominal outside diameter of the male spline the u-joint is intended to fit, in decimal inches, and in millimeters where the profile was originally a metric design.

In production, a spline is measured over wires of specified diameter which fit into the vees. Since it’s seldom practical to do this in the field, we suggest you simply measure over the crests of the teeth. That measurement will usually correspond closely enough to one of the listed diameters to identify it.

Keep in mind that splines fit on the flanks of the teeth, not the crests. Like screw threads, the crests of spline teeth can be truncated without affecting the fit, so an actual measurement of any of these examples might well be .015 (0.5mm) under the nominal sizes shown here. To aid identification, the vehicle origins of the various automotive splines are also listed below where known.

The “number of spline teeth” refers to the number of equally spaced divisions of the circle, whether or not they are used in the spline pattern. Flats or interruptions are ignored (e.g., a shaft with 36 teeth, 6 of which are missing, is NOT a 30-tooth spline). If interruptions make it impossible to get a reliable count all the way around the shaft, count halfway around and double it.

 

201 .750 diameter; 20 teeth Used on all Woodward products since 1992; fits Woodward integral power racks, Woodward remote power racks, Woodward servos, and Woodward
safety steering columns, weld-in stubs, and double u-joints.
Also used on copies of Woodward columns. Not an automotive industry profile.
The shaft spline OD is cylindrical and can run in a bearing.

101 .750 diameter; 48 teeth Fits most US stock-car racks past and present (Sweet, Appleton, Speedway, SWS, Quick-trac, Wilwood, Coleman, BRT, RCP, and pre-1992 Woodward) and the output end of inline Sweet servos. Originally a British standard used on MG and Jaguar racks and Austin-Healey steering shaft, among others. Note: Over the years this profile has been applied to many products without reference to the original dimensional standard; a proper fit cannot be guaranteed on parts made by companies no longer in business.

102 .735 diameter; 36 teeth Fits Mustang power rack and its clones, old manual Chevy and Ford box, Dodge truck power steering box, and most steering quickeners. Note: This is an automotive industry profile whose production tolerances varied during the half century it
was in use.
Some older aftermarket shafts and steering quickeners with a “3/4-36 spline” do not
conform to this profile and may not work with this joint.

103 .720 diameter; 30 teeth Introduced on 1980s GM power steering boxes and racks.
Used on current Delphi 600 series boxes and on aftermarket servos using the Delphi 600
input shaft (Appleton, small style Sweet, etc.). Interchangeability of this profile is fairly
reliable. Usually has a large flat on one side.

104 .820 diameter; 36 teeth Used on older GM power steering (700 series boxes) and the
input shaft of large style inline Sweet servos. The measured diameter varied considerably during the years of production of the steering box, from .812 as originally produced,
to .820 on later units. Usually has a large flat on one side.

105 .620 diameter; 36 teeth OEM Chevrolet Vega steering box (NOTE: may not fit “5/8-36” aftermarket copies of the Vega box).

106 .565 diameter; 26 teeth Fits Ford Pinto manual rack and pinion and most aftermarket copies.

107 .625 diameter; 36 teeth Made specifically for the Stiletto (Chassis Shop) manual rack. A special profile; not an automotive standard, and NOT for Vega steering boxes.

108 .688/17,5 mm diameter; 34 of 36 teeth)  Fits Toyota truck power steering with one filled spline for orientation, also other 17,5 x 36 splined shafts.

109 .750 diameter with two fats (“double D” shape)   Fits Ford style DD shaft and street-rod aftermarket DD shafting measuring .550 across the fats. Does NOT ft the smaller 17 mm GM DD shaft.

110 .563 diameter; 36 teeth  Fits Titan, Jack Knight and Miller racks, Ariel Atom steering shaft, also some dragster steering.

111 .625/16 mm diameter; 23 of 36 teeth   Originally made to ft the Australian TRW power
rack with 13 blocked or flled splines, this also fts the 16 mm x 36 spline shaft used on
various Japanese cars.

112 .590/15 mm diameter; 29 teeth   Fits Honda rack and pinion and steering column and some aftermarket midget racks.

113 .570/14,5 mm diameter; 28 teeth   Fits Datsun 240/260/280Z. The other end of this
u-joint can be sized for welding onto the original steering shaft.

114 .669/17 mm diameter; 36 teeth   Fits Mitsubishi Starion, Chrysler Conquest and EPAS electric steering columns.

115 .688/17,5 mm diameter; 54 teeth  Fits ZF steering rack and splined shafts used on many European cars such as BMW, Mercedes, Ferrari, Maserati. 

 NOTE: On some recent steering racks, this spline does not conform to original spec.  Referring to the drawing below, although
  both specifications show this spline as having the identical pitch diameter, the profle on the right has a 3° wider included angle. 

We have resolved this confict with special tooling. The #115 U-joint as currently produced will now fit all ZF pinions old
and new.  If in doubt, we suggest a trial ft using a C115 coupler.

116 .550/14 mm diameter; 34 teeth   Fits Toyota MR2 and Corolla steering rack and Quaife quicker-ratio replacement gearsets.

 

 

Plain bore sizes for welding onto steering shafts.

100 .755/753 diameter   Sized for a close slip fit on 3/4 inch cold fnished TUBING.
Mills normally produce tubing to a PLUS tolerance.

 

Plain bore sizes for welding onto steering shafts.

150 .625 diameter   Sized for a close slip ft on 5/8 cold fnished BAR STOCK.
Mills normally produce round bar to a MINUS tolerance.
