Windscreen not being fully wiped

[Rincewind]

Not quite MOT time yet but not too long.

When the wipers wipe the cleared area doesn't overlap, there is a section of about 3/4" which is missed. I am guessing this isn't correct but what is causing it.

I read a previous thread about TR6 gearboxes being almost identical but giving a different throw, there are wiring splices between motor and gearbox so I think one or other has been replaced at some time.

I have had the top off and there are three holes in the large gear but the pin is mounted into the outer one which should give the biggest throw. Rimmers have a replacement but at £30+ I would like to be sure it is wrong, so, is there any way I can check it is the wrong gear or could there be something else that is wrong or worn out?

Thanks

I get the same. Top tip don't drive a STAG when it rains. I don't think it would fail an MOT on that alone. Mike

Hi Keith, I'm guessing it's your left wiper that isn't overlapping, set it so that it parks a little higher, i.e. covering the tax disc, and do it with the windscreen thoroughly wet. These are rack and pinion wipers that the industry - rightly - gave up on decades ago, unless you've got new wheelboxes and a new rack, you'll never get them perfect. Your motor gearbox sounds fine. Enjoy Martin.

Thats great guys, will adjust the left one tomorrow.

Mine don't overlap when it's dry but are fine when it's wet.

Don't use wipers, use RainX. Brilliant stuff!
