Title: speedo repair - needle removal
Post by: hoogerbooger on 03 Sep, 2018, 11:24
I watched some youtube videos. Piece of card slid under the needle and then carefully with 2 levers prize off.

I've tried &  dare not prize harder. Seems to be stuck. Possibly a little rust on the shaft ? from condensation  ?

I've applied a drop of WD 40 onto the centre of the needle/spindle joint. No luck.

So should it have come off easily ? seem to on the videos. any tips that might work without destroying the speedo.

Some speedos they come off easily and with other they are very difficult. Everything is quite delicate and easy to wreck the instrument.

I warmed mine up with the tip of a soldering iron . A small gas operated one . Came off easy after that .

They are just a friction fit onto the spindle.
Don't just pull the needle - the shaft needs to be supported. If it is tight, then possibly heat from a soldering iron and a tiny bit of WD40 or just use 2 pairs of fine needle nosed pliers - one to hold the shaft and the other to gently ease the needle off.

cheers

I'd been thinking I can't heat it easily without damaging paint on the face. Hadn't thought of soldering iron. I've used a jet cigarette lighter before to heat localised areas but think this is too risky, so I'll try a low power electrical soldering iron.

Will also try freeze thaw a few times, then heat after it's thawed.

unfortunately I haven't got fine enough needle nosed pliers...so will start looking for

fingers crossed

WD for a couple of hours then use a trim removal tool.   https://www.ebay.co.uk/p/Sealey-RT0042/1961896119?iid=310959345472&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D20140122125356%26meid%3Db5c222c1c5584538a19aaa2dec5f4ade%26pid%3D100005%26rk%3D2%26rkt%3D8%26mehot%3Dag%26sd%3D311274616313%26itm%3D310959345472&_trksid=p2047675.c100005.m1851
