Fitting a New Windscreen Seal

1 ) First buy a new seal, this can be purchased from NTG or Woolies a 3 metre length is required and the code for the Woolies seal is R156.

 

2 ) Remove the windscreen, this is done by first removing the two screws that hold the central winding mechanism in place at the bottom of the frame. Now prop open the screen with a short length of wood.

 

Disconnect at Winder.Top hinge bolt.The two top hinges will now be visible. These are adjustable and it is a good idea to mark their position before undoing the set screws. This will make refitting easier and possibly avoid having to fit by trial and error. After the set screws are removed the screen will lift away easily.

 

3 ) To remove the old seal prise it out with a small blunt screwdriver at the centre top and then it should pull out in one piece. If it is really perished and breaks up, all traces of the old rubber will need to be removed to allow the new seal to sit in freely.

 

4 ) Once the old seal is removed the frame joining screws will be exposed on the two ends, if the glass is to be replaced or a new inner seal fitted around the old glass these will give the access required.

Joining screws exposed.5 ) Depending on whether you are right or left handed decide by experiment which is the best direction to fit the new seal. Start at the bottom and work around, the deep groove in the seal fits in first and the narrow ridge on the other side will thumb into place quite easily on the straight. A rubber lubrication spray will make it really easy. At the corners the small blunt screwdriver may be needed again to force it into place. Keep checking to ensure it has dropped right into the groove. When it is in properly it is quite moveable in the slot.

Rounding the corner.

6 ) Once you have fitted it all the way around, work it back along the groove in both directions to make sure the rubber has not been stretched. Failure to do this could cause the joint to work apart as the rubber contracts in future cold weather. Also a good reason to glue the joint on completion.

 

Pressing in with a blunt tool.7 ) Now sharpen your sharpest blade, pull out the seal for a few inches in each direction and mark the joining position in the centre bottom. Give each side an extra couple of millimetres and cut the seal dead square. Thumb the seal back into place and check the joint. If the two surfaces do not quite butt up together with a clean joint a thin slice can be taken off to make the perfect fit. If the seal does not sit in its seat evenly all the way round because it is too long then further slices can be removed from the ends.

 

8 ) Finally pull the two ends out from the frame for a couple of inches and Power Bond them together. After holding the ends together for a couple of minutes you will have an unbreakable joint and the seal can be thumbed back in to place. I have bought Power Bond regularly from the stand at Stoneleigh and it does exactly what it says on the label.

9 ) Refit the screen using the wooden stay and line up the marks made on the hinges before tightening the set screws. Allow the screen to close and check to see that there is an even pressure on the seal all the way round. If not go back and adjust the hinge with the set screws.

 

10 ) Re fit the two small screws that hold the winding mechanism to the bottom of the frame and tighten the screen back in place before making the final check for even pressure.

 

11 ) Give the glass a good clean then stand back and admire your smart new screen.
