FITTING OF DIFFERENTIAL AND REAR BRAKES

1

 

Fitting - Differential 

1  

Locate two M12x65mm bolts from your 
parts and fit a spring washer followed by 
a standard washer to each. 

2  

Place  the  M12x65mm  bolt  into  each  of 
the two top mounts (Fig1.1). 
 

 

1.1 

3  

Before  positioning  the  differential  [C]  a 
washer  needs  to  be  fitted  on  the  bolts, 
the  washer  will  sit  between  the 
differential and the chassis bush. 

4  

Lift  the  differential  into  position  taking 
care  not  to  knock  the  washers  off  the 
inside of the bolts (Fig 1.2). 
 

 

1.2 

5  

Screw  in  the  top  two  bolts  do  not 
tighten at this stage. 

6  

Locate from your parts the M12x300mm 
stud 

7  

Position  the  stud  into  the  lower  chassis 
bush differential mount. 

8  

Place  a  washer  between  the  lower 
mount of the differential casing and the 
chassis  bush  and  push  the  300mm  stud 
partially into the differential housing. 

9  

Place a washer between the differential 
and the other lower chassis bush. 

10  

Push  the  300mm  stud  all  the  way 
through. 

11  

Place a M12 washer on to both ends of 
the lower differential stud. 

12  

Secure  with  M12  nyloc  nuts.  Torque  to 
54Nm  (40  ft/lbs)  and  torque  the  top 
bolts to 40Nm (30 ft/lbs) (Fig 1.3). 

 

 

1.3 

13  

Locate  the  stabilizing  bracket  [F]  from 
your parts. It is mounted on the rear of 
the  differential  housing  and  is  secured 
to the chassis via a metalastic bush (Fig 
1.4). 

14  

Attach  the  bracket  to  the  differential 
using two M10x25 set screws and spring 
washers.  The  bracket  should  be 
positioned  so  that  the  bush  is  at  the 
bottom. (torque to 27Nm (20 ft/lbs) 

 

 

1.4 

 

 

15  

Locate  a  7/16”x2  ½”  bolt.  Put  a  plain 
washer on the bolt. 

16  

Insert  the  bolt  through  the  chassis 
bracket  securing  the  stabilising  bracket 
to the chassis. 

17  

Place  a  washer  on  the  end  of  the  bolt 
and  secure  with  a  nyloc  nut.  Touque  to 
27Nm (20 ft/lbs). 

18  

Undo  the  oil  filler  plug  with  a  10mm 
allen  key  and  fill  the  differential  with 
(type EP 80/90) oil (Fig 1.5).

Fitting – Drive Shafts 

NOTE: 

The  driveshaft’s  are  sided,  with  the  right 
hand one being slightly longer. They are also 
marked LH and RH. 

It may be necessary to undo the upper rose 
joint of the upright to get the driveshaft into 
position.
