Wiper arm removal (Griff)

[gopher]

Hi All,

I'm about as useful as a chocolate teacup when it comes to spanner wielding but thought that a simple job like this shouldn't be beyond me, it seems I'm wrong.

Retaining nut has been removed and I thought the remainder of the existing arm would then lift off, I would put replacement arm back on, re-secure nut and that would be it, however the arm appears to be very solidly attached to the bolt.

There is a larger nut under the arm and whilst this loosens it does not appear to make any difference, also I'm wary of applying too much pressure in case I do more harm.

Any pointers?

Thanks

Paul

Soak with Plus gas then lift/lever off carefully

So I'm correct in thinking that the arm should lift off? Is Plus Gas like wd40?

Thanks

If it's like my '99 Chim then the arm should lift off the threaded section (which is also splined). The threaded section stays attached to the bulkhead and so you should only need to undo the top nut, which you've already done.

If it helps understanding Gopher the arm sits onto a tapered spline. The retaining nuts often get over tightened and due to location this means the splines oxidise readily. Any penetrating oil such as WD40 will help to break this down.

It may need a good wiggle to free it from the spline as well.

Thanks for the replies.

My main worry was that the arm was attached to the spline in some way other than just the nut and so did not want to apply undue pressure, you see while trying to twist the arm off (gently) I noticed that the only effect was to move the other wiper arm, hence my post.

Knowing now that it should just lift off (with a bit of encouragement and lubrication!) means I can continue to wreak havoc. WD40 soaking in as we speak, it does seem quite well welded to the spline.

All part of the learning process at this rate I'll be able to do my own servicing in about 40 years time

Thanks again.

All sorted,

Took some soaking in WD40, I suspect it's been there for some time, probably 16 years!

Appreciate the help,

Thanks
