(Note my wipers were actually defective and replaced in the Post Build Check. The ridges inside the wiper arm were so weak that they all broke off when I tried to use wipers. Apparently this has happened to a batch of wiper arms)
Caution – The wipers move from RHS to LHS – ie the opposite way to how they are shown in the manual!!
Wipers are a very simple mount onto the motors which are protruding in front of the windscreen. You may need to trim the end of the wiper so that it is not too big for the screen. These motors have very small ridges on them that align with the ridges inside the end of the wiper arm. There is then a small clip which holds the wiper arm in place.
Turn wipers on and off again using switch in car while no wiper blades are attached. When you turn them off, the wiper motors will return to the stopped position. Then push the wipers on. Be very careful if you lift these wipers up – they snap back down viciously as the springs are very strong. I did it once on the windscreen and chipped some paint off the edge.
Once you have them mounted, fill the tank in the boot with washer fluid. You can mix the caterham supplied fluid with water (I had spare distilled water so used that) in any proportion you like. The more water, the higher the freezing point. If you go pure washer fluid it will be fine down to -26c but I don´t intend to go out in that! I used approx 70 fluid/30 water, it doesn´t need to be exact. Now check the pump works by hitting the seperate button inside the car for the jets. You may need to adjust the jet positioning – a needle in the jets can help reposition/swivel them to improve aim.
Wingmirrors – there are apparently multiple options for wingmirrors on a caterham, including ones that mount on the doors themselves. The IVA pass mounting point is on the side of the windscreen. You´ll note that once you fix the wingmirrors here, it restricts the travel of the doors somewhat. However, I don´t intend to have the doors on the car that often so it doesn´t really bother me too much – I will probably stick with this point, but may upgrade mirrors later if required.
Each mirror should come with two IVA mounting kits (Caterham part MR06K) and the mirrors themselves are from Ford. Keep one wing mirror box, and place all spare parts from this in that box in case you need them later.
Remove the middle screw from the side of the windscreen and place it in the box in case you decide to change mirror option later. Place the fibre washer onto the mount stud, apply some loctite, and then screw into the screen. Do this on both sides and allow the loctite to set.
Gently offer the mirror mount up to the stud which is attached to the windscreen and see if it fits on. You may find that the hole is not wide enough – due to powder coating or the famous tolerances discussed at length…
If this is the case, you can open up the mirror mount with an 8mm HSS drill bit.
Easiest to do this part before attaching mirrors. You don´t want it too loose, but once you can actually get the mounting arm on the stud, prep the mirrors.
The mirror itself comes attached to the stock stem and can be removed using a T20 torx adapter. There is a ball joint contained in the mirror that this T20 screws into. Be careful if you face the mirror downwards, as the ball joint can fall in. If you can, try to keep the mirror glass facing upwards. Put the stock mount back in the box and then attach to the SVA mounting kit arm – including the mounting . Tighten up with the T20. It can be a bit of a pain at first to get this to bite. You can use pliers to hold the ball joint and stopping it from spinning while you tighten.
Once you have tightened enough to build some pressure, you can remove the pliers and fully tighten up.
Now place the completed assembly onto the mounting stud and tighten up the grub screw with a 2.5mm allen key.
Rear view mirror – simple attach job on the top of the windscreen. Apply some masking tape to the very top of the windscreen frame, then measure from the sides to get the mid point. Clean windscreen with some cleaning alcohol, let it dry, then attach rear view mirror.
