Title: A7 52 Plunger headlight switch/ammeter panel rubber seal
Post by: larryc on 11.07. 2015 15:40
The headlight switch/ammeter panel seal was shot when dismantled, I am ready for re-assembly and wondered if they are available, or has anyone used an alternative material, the original had 3 x rubber spikes to locate in 3 x matching holes in the headlight unit, I have been thinking on the lines of black door seal stuff, any suggestions will be very welcome.

Couldn't find them either.
Ended up by cutting a 2 mm o-ring to fit the groove and glued the ends together with super glue.
Seems to hold well.

 Isn't it normally a length of 'O' ring type rubber (~2mm) threaded through those holes, or held in with those small 'clips', and open ended at  the bottom end...?

Thanks Dutch and Morris, I will try the 2mm 'o' ring, the one I took off had three pips on the rubber to fit into the holes, but as you both suggested the panel should hold the 2mm rubber. Cheers, Larry.

 I can't remember where I got that info, but have an idea, will chase it up- I also can't remember if I used it or he didn't have some and I just used a bead of silicon or similar...

 edit; 2 minutes later...well bugger me, I did a search for "Lucas switch panel seal", and the first result is the guy who told me about it- still doesn't have any...but the details are there  he's a local guy here

Thanks for your help, I have ordered 1 metre of 2mm 'O' ring from Ebay £1.99 inc delivery, thanks everyone, Larry.

 update;-
     Just by chance looking for ammeter part number, came across this again. I've had the meter panel off a coupe of times the last couple of weeks, and discovered I don't have anything other than 3mm 'O' rings under each screw, and as I don't have the three 3whateverBA screws have improvised with SS ~5/32"ww  screws with nylock nuts.

 Off topic, I finally put some thought in and've come to realize that my +/- 30 Ammeter is likely from a Massey Ferguson tractor (stamped on back#36047B); does anyone know the stock prt#/ ...? Doesn't matter too much but a lesser deviant range would be more indicative of what's happening

 I'll go looking for a more better topic *eek*
 Cheers

Dutch,
                  You want 36084F which is a model CZU27.  8-0-8 amps but is marked --0-+
They are being made by Lucas again but one I installed recently fell apart before I put it into the headlight. It was badly assembled so I sealed it up with Silastic. It works OK.

 Thanks Trev, good to know about the flimsiness- is it a metal body or like the clear plastic ones I've seen?   

I actually found the info in Brians post here; http://www.a7a10.net/forum/index.php?topic=4183.msg28360#msg28360 (http://www.a7a10.net/forum/index.php?topic=4183.msg28360#msg28360), but by that time was had hit full personal discharge and dozed off

 I also found another thread where you said  the 12 A +/- were for 12V, which intrigued me; Ill find it again and address it there

 EDIT; my mistake I read it wrong; found it here:

 I'll go there

Clear plastic, similar to original but the back plate is Tufnol unlike the plastic of the original. I don't think that they are necessarily flimsy, just a quality control issue in my case.

 Just another update on the "headlight switch/ammeter panel rubber seal", when I was at the bearing shop the other week, i asked if they had any 2mm rubber "whatever it's called", he set me straight and sold me a metre of 2mm " Buna-N-Cord", so if anyone needs some that's where to get it.

I'm half way through the SR headlight and dash panel and was wondering if there was some rubber insulator between them, and now I know. Thanks

Yep, mine fell apart too Trev, (same gauge) so I fitted a volt gauge in the hollow case  http://www.jaycar.com.au/Test-%26-Measurement/Panel-Meters/LCD/Panel-Surface-Mount-LED-Voltmeter-5-30VDC/p/QP5582   Cheers TC
