Wiper arm sweep
Is it possible to adjust how far the wiper arm sweeps? On the drivers side the wiper arm does a good job of wiping the windscreen rubber and I would rather the wiper didn't.

I have the arm set so its about as low as it can get when resting, but in operation, it sweeps too far. 1999 Defender TD5 110

Believe 115 degrees is normal.

Or you can DIY it https://youtu.be/EpG9P6auilk

Cheers. So the only way is to replace the cog in the wiper motor? 1999 Defender TD5 110

Very useful - thanks. I think I need more like 100-110 degree sweep.
If 115 is standard then I wonder why my wiper likes to clean the windscreen seal ? 1999 Defender TD5 110

How much play do you have in the wiper arm? Usually when Defender wipers start hitting the windscreen seal it is that there is play in the wiper wheel box or in the spindle. It is worth checking that the wiper nut has not come loose as well.

And I think I was wrong. I think that 110 degrees is normal, although mine do not seem to go past 90 degrees.

When I next have a look in the dash I will check what cog is in there.

I have recently done new splined adapters and new wiper arms. There is a little bit of play but not what I would call excessive.
Wiper nut ? just splined adapters and a grub screw on my wiper arms. 1999 Defender TD5 110

Well just for completeness sake

Pre 2002 - 1A 622423 VIN - 517646 - 110 degree sweep

Post 2002 - 2A 622424 - DLW000020 - 140 degree sweep

Which is interesting because My 2003 definitely does not sweep 140 degrees Rolling Eyes

Land Rovers, nothing is ever straight forward... Rolling with laughter

Yeah not a fun solo job, but worth it for decent wiper motion Smile

Those VIN change over points mean jack... Rolling with laughter

When it comes down to stuck wiper arms on spindles, this is what id did to get mine off. May help someone else at some point.
