3000 Ashcroft Air lockers sold to 26/9/14 with zero failures to date !

This model is to suit the "Rover" type 24 spline differential fitted to the Discovery I, Discovery II, Range Rover Classic, 90 & 110 front. We can supply the Ashcroft Locker on its own for you to install or we can build them into diff casings for you. Whatever spec you require, whether it be diff "pegging", or with standard 3.54 ratio or our uprated heavy duty ring and pinions, we can build them to your needs.

Note we only supply 24 spline, these are not available in 10 spline.

Please note that you will need to drill and tap a hole in the diff housing for the air feed pipe to pass through. We are able to supply the drill and tap should you require.

Note we can fit the locker to your diff assumings its in good running condition

We are able to offer a complete spare parts listing. Please see the exploded diagram below to help identify which parts you may require.

Please note if you opt to have a turned locker then there may be a small delay in dispatch of your order

 

Spare parts are listed in our product codes ASH-AL01 to ASH-AL-42

User Guide

The locker can be engaged in theory at anytime that you have zero wheel speed difference, ie at a standstill or driving in a straight line but we would advise only locking below 20 mph due to handling considerations. Do not lock when you have a high difference in wheel speed ie when stuck and wheelspinning. When engaged you can expect it to lock in under 2 seconds, unlocking may take 3-5 seconds depending if the lockring is undertension due to 'wind up'. Beware of crossing side slopes with the locker engaged as this may encourage the rear to swing downhill.

Installation Information

INSTALLATION GUIDE

We have separated our installation guide into four main categories.

 

1) Installing your locker into the differential,

Remove the stock diff centre but be sure to mark the bearing caps so they are refitted on the correct side, Drill and tap the diff housing ¼ BSP here :

 

 

Fit the crown wheel to the new centre, install locker and set preload and backlash as per factory specs. There are two lengths of Journal end cap bolts used, 50mm for the non dowelled cap and 60mm for the dowelled cap, select the bolt 5mm longer than stock to fit the cylinder locking tab so that the tab stops the cylinder rotating, see below.

 

2) Installing the Air Lines

The solenoid is marked as shown and should be fitted as follows:-

 

P = Air Compressor

R = Exhaust

A = Diff (blue pipe)

 

Once the air compressor is mounted remove the nut and coil from the solonoid and fit to the air compressor with the 1/8 BSP M/M nipple, see photo below, it must be this way round:

 

 

Fit the 1/8 tapered 90 deg push fit elbow to the other port. Refit the coil:

 

 

Fit the brass 1/8 parallel 90 deg elbow compression fitting to the locker cylinder and fit the copper pipe to this fitting, pass the other end through the tapped hole in the diff housing. We would suggest fitting the pipe like this to allow some flex in the pipe :

 

 

Once the copper pipe is through the taped hole, fit the brass adapter nut from the outside and mark the pipe flush with the brass nut, remove nut and cut pipe, refit nut, fit the small O ring, fit 1/8 parallel 90 deg push fit elbow.

Fit air line between this push fit connector and the one on the solenoid.

 

3) Installing the switches and electrical connections

 

Rear switch

Pin 8, dash illumination, on ARB loom is blue/white (shows red bar when side light on)

Pin 7, ground, on ARB loom use black (either one)

Pin 2, feed, on ARB loom use red

Pin 3, to rear solenoid, on ARB loom use yellow

 

Front switch

Pin 8, dash illumination, on ARB loom is blue/white (shows red bar when side lights on)

Pin 7, ground, on ARB loom use black (either one)

Pin 2, feed, on ARB loom use yellow

Pin 3, to front solenoid, on ARB loom use green

 

Connecting to the solenoids

The connector on the ARB compressor loom cannot be used so please snip this off and crimp on the 2 spade connectors supplied with the locker, connect these 2 spades to the 2 parallel pins on the solenoid.

 

4) Final testing

 

Handbrake off, Centre diff unlocked, mainbox in neutral, Jack up one wheel, the wheel should spin freely, Switch the air compressor on, allow it to run up to pressure, Select the locker whilst spinning the wheel and it should stop dead.

Switch the locker off and the wheel should spin freely again.

Please note if you are using your own air compressor we would suggest using between 70-100 Psi,

 

Torque Settings:

Crown Wheel Bolts: 58 Nm

Bearing Caps: 90 Nm
