half shaft data and useful stuff

Recommended Posts

In Oct 1999 LRM is a two page article listing half shaft data for various land rovers. Stuff such as spline count, diameter, material strength etc: Also list of aftermarket half shaft manufacturers.

Ok, it is 6 years old but may be of some use.

This may be useful for the TECH section.

Is anyone willing and able to host the pages, then I can scan and e-mail them to ya?

axle specs post

RANGE ROVER DISCOVERY AND DEFENDER WITH ABS:

All vehicles with ABS brakes have the CV joint with the small weak 32 inner axle spline. The CV joint also has 72 serations on its outside dia. for the electronic sensor to "read" wheel speed from. The heavy duty AEU2522 CV joint can be fitted with a 72 tooth ring which is shrunk onto the body of the CV. However this increases the dia. of the CV which then means the inside of the hard chrome swivel ball has to be machined to provide clearance. The top swivel pin also has to be raised 2mm. to clear the 72 tooth ring. ABS sensor is adjusted to just touch as per normal set-up.

SPLINE SIZES & TOOTH COUNTS

10 SPLINE: Used for axle shaft to diff side gear in ROVER Type diffs from the first L/R in 1948 to app 1992. Also used in L/R series 1 & 11 vehicles at drive flange and early R/R & Disco CV joints.

Square form (40 o included angle) Major dia 28.2 (1.11") Root dia 25.3 (.997") Zp ( polar section) .212

App torque capability for axle of 1500 Mpa UTS Hytuf 5635 Nm (4160 ft lbs)

24 SPLINE: Commonly referred to as "Salisbury" spline as it first came into rover use in the Salisbury diff fitted to series 111 long wheel base. Also used at drive flange on series 111 onwards. From app 1994 the Rover Type diff also uses this spline in the side gear although this gear is about .004" tighter than the Salisbury diff gear. The side gear spline in all Maxi-Drive 24 spline diffs is also the same as the Salisbury. (Why Rover decided to depart from industry standard and make the Rover diff tighter is anyone's guess)

Involute form, flat root side fit, 20/40 DP, 30 o PA,

Major dia 31.4 (1.24") Root dia 29.2 (1.15") Zp (polar section) .294

App torque capability for axle of 1500 Mpa UTS Hytuf 7835 Nm (5780 ft lbs)

23 SPLINE: Only used as the inner axle to CV connection on the three decent CV joints, namely R606665 R/R ; AEU1828 stage one 111 and AEU2522 early county

Involute form, flat root, side fit 20/40 DP, 30 o PA,

Major dia. 30.1 (1.18") Root dia 27.9 (1.10") Zp (polar section) .281

App torque capacity of axle of 1500 Mpa UTS Hytuf 7450 Nm (5500 ft lbs)

32 SPLINE: This is the hopelessly small inner axle to CV connection used on all vehicles since app 1988. Not strong enough for the torque that can be applied with a across axle diff lock. For this reason all front Maxi-Drive diff locks use the more durably 23 spline size and if required the stronger 23 spline CV joints are used in place of the weak 32 spline CV joint.

Vee form 45 o PA, Major dia. 26.3 (1.035") Root dia. 24.1 (.950")

Zp (polar section) .192

App. torque capacity of axle of 1500 Mpa UTS Hytuf 5095 Nm (3760 ft lbs)

Tony it is like what you posted but in a table so is more readable, well I think it is. So no takers?

Yes you can.

The gallery will host pictures for use on this website.

Just upload them from your pc and then link the pictures to your thread on any of the forums, the same as you would do with photobucket etc.

Les. :)

Except that scans from a magazine would be in breach of copyright, so unless it's okayed with LRM first we'd have to remove it to protect the forum legally :(
