Seat lumbar pad adjustment handwheel
 

Does anyone know how to remove the centre cap (cover) from the handwheel, without damaging the handwheel itself? Nothing to get hold of.

When I recovered my seats I just gave it a good pull and off it came , I'm sure someone has done a how to on here

I now have an example off the seat (not mine). Yes it just snaps in place, I can do the one in my hand but the one in seat still refuses to come apart:mad::mad:

I had exactly the same trouble a couple of years ago. I eventually came to the conclusion that there was possibly a nut under the knob's round central disc . I carefully cut this out. There is nothing holding it inside, and the adjuster is still firmly in place.

After putting an enquiry on this forum, one reply stated that it almost fell off without any effort. We must be trying too hard

Having worked in the trade for a very long time , I've come across this problem myself several times .
A little tip that I found very useful for removing these little blighters is to get a bit of rag and push it in behind the wheel . Tuck it in as far as you can get it then pull the remainder of the rag forward so it completely wraps the wheel up .
Then pull and it should come off .
By using the rag your simply spreading the pulling pressure right around the wheel . Might take you a couple of goes but you will get the general idea after your 1st attempt :D

After seeing Lottysvdub's idea above, this morning, I decided to give the rag idea a try. I had no luck so I used two flat garden trowels slid in from either side, one above the spindle and the other below. These were done with the adjuster knob in the "centre" of the adjustment.

After a couple of strong jerks on the handles the knob came away and two 'half-sleeves' shown in pics 1 and 2, came away from the rear of the knob. This is my first entry with photos, thanks to Arctic's method. the third picture is looking from the seat-side of the knob showing the splines.All I have to do now is replace these parts onto the spindle end on the seat-back.
