P1800S Indicators

[Waddii]

Before I remove the steering wheel one more time I wondered if anyone can tell me what I am doing wrong to have 'self engaging' as well as 'self cancelling' indicators!

Inside the top part of the steering column assembly, where the switches are housed, is a cylindrical steel component with a flange one one side which is clearly there to cancel the indicators. It can be rotated independently of the column. It has a small slot in the flange which tempted me to put the steering wheel on so that the little peg on the bottom of the steering wheel hub engaged with the slot in this flange.

Result: Put indicators on, go round corner, straighten out indicators 'self cancel'.

Perfect BUT: Indicators off, go round corner, indicators 'self engage'! Aaagh...

Should the peg not be in the slot?

Any advice on how to get rid of this unwanted side effect.

Waddii;

I'm not intimately familliar with the 1800 cancelling mechanism, but I wouldn't be surprised if it was similar to the 122 mechanism where the "Cancelling Collar" turns with the Steering Column and works upon the switch mechanism to cancel it when engaged...it's up to you to figure out how it is "self engaging"...I expect that will require you to take it apart again...

Maybe a look at the 122 Mech will shed some light...see also: http://www.sw-em.com/Directional_Ind..._Mechanism.htm

Good Hunting!

Edit: You might want to document this work well with some pix, for the next owner who needs to get up-close-and-personal with the mechanism...(if you can't post on a site, I could add it to SW-EM page article...)

Hi

you are right, that the slot is for the peg to turn it off. Do you have a steering wheel boss fitted by any chance. You may have it over tightened

Thanks Both, looks like the blasted thing will have to come off again then! I'm sure, looking at the link you kindly provided, it is a re-use of the 122 mechanism. It could well be a lube or even alignment issue I expect.

I let you know what I find.

I made it do that once... unfortunately I can't remember much about it so long afterwards.

The one thing I do definitely remember is that it was some kind of misalignment problem when putting it back together.

Rather more vague memories include...

- it being a bit touchy/fiddly to get the alignment actually correct, as opposed to just seeming to be correct but later turning out not to be.

- something about the two return levers (see Ron's link) being able to go funny somehow and start being engagement levers as well.

- the usefulness of repeatedly checking it's still working at every further stage of the reassembly process.

Basically I think you need to have a good peer at it with a good light while you take it apart and wiggle things and see what catches on what where and what doesn't

Just spent an hour taking the steering wheel and indicator cancelling mechanism apart. It turned out the link Ron sent was very helpful indeed and the problem was just 50years of detritus and drying lubricants. A thorough clean and lubricate has sorted out the problem. The drag caused by the goo was enough to give the unwanted indicator engagement.

Thanks to everyone, especial Ron.

Waddii;

Detritus...funny...I know that from the bottom of the aquarium...or under the couch...I suppose it can also occur in automotive components...

Did you take any pix? Was mech similar to 122 mech?

Thanks for the kind words.

Cheers

Hi Ron,

The mechanism is the same as the 122 in the link and so were my pics! So, nothing useful to post really. I cleaned everything with WD40 and paper towels first and then lubricated with some new grease on the column and the companion piece contact areas plus a squirt of electronic contact cleaner on the switch springs and levers. I checked the little pin on the steering wheel engaged in the slot in the companion piece, put it all back together and he presto it works perfectly!

Cheers
