Head lamp replacement

Disassembly: words and pictures by Tim Woolcott.
Reassembly: words and pictures by Rob Bell

Introduction

Headlamps may need to be replaced for a variety of reasons, from accident damage, to replacing lamps whose inner dipped beam diffuser lens has yellowed. These instructions can also be used where headlamps are to be disassembled for painting (a la Trophy 160) or for sending the reflectors away for re-silvering (these instructions can be found here).

These instructions are also useful for those contemplating removing the front bumper on an MGF, or indeed planning to replace the front grilles

Parts required:
  • 2 headlamp assemblies ( approx. 70 each new)
  Tools required:
  • 10mm Socket
  • 17mm Socket
  • Philips screwdrivers
  • Stubby Philips screwdriver would also be handy.
  • Large Flat screwdriver
  Time:
  • Approximately 45 minutes  - a spare pair of hand can be useful.

Removal
1 Remove indicators with flat screwdriver to carefully prise open the catch that retains the indicator lens in position. You can use a cloth to protect the bumper paintwork if necessary. DSC00644.jpg (17138 bytes)
2 Unbolt two 10mm bolt on top of each headlamp. DSC00646.jpg (21830 bytes)

7 Completely remove the screw nearest the wheel (out of shot, but arrowed) and loosen the screw pictured deeper inside the bumper (vertical arrow, opposite).

Repeat steps 6 & 7 for the other side.

I've also included a picture showing the inside of the bumper grills for those wanting to change the standard black grilles for Trophy or Abingdon-style stainless steel items. The multiple locating self-tapping screws are arrowed, opposite.

Re-fitting
1 Re-fitting of the head lamps to the car is effectively the reverse of the disassembly instructions. However, there are a couple of areas to highlight. First is illustrated opposite, right. When replacing the headlamp bowl, note the location of the rectangular locator hole on the front cross member - this is circled on the image, right.
2 This corresponds with a locator lug on the base of the headlamp assembly. Ensure that it slips in to the hole, or else the headlamp will not sit correctly when the whole bumper assembly is replaced.
3 When the bumper has been replaced onto the car, all that remains is to check the headlamp arrangement - a garage door or wall is ideal for this process - as indeed are dark ambient light conditions!
