Help - Identify - Small - Widget

[foureyes]

Hi - I'm new to the forum and like most newbees have been lurking in the background soaking up all the advice.

First post as I haven't spotted this in the forums and can't find the answer in the Clymer manual.

I'm hoping that someone can help me identify the small widget that I found when opening the clutch cover.

I have no idea where it came from it just dropped into the cover when I removed it from the crankcase.

The electric starter fix is now complete but I don't want to replace the clutch basket or go any further before checking that this noggin shouldn't be living somewhere behind the clutch.

Any help gratefully received...

more pics please from different angles would help

 

[lowerc]

yup, looks like a widget to me......

Looks like one of the rivets that hold the clutch hub together. Pull it back off and take a look.

Hi foureyes,
'ow bist thee our kid? do they still speak Bedminster dialect back 'ome?
As to the widget, do the photo like on the CSI shows, up close with a ruler next to the part. Perhaps more than one view, too.

I'm thinking it's part of the shift rocker.

I see a clutch basket rivet. You can find useable replacements on eBay. Try to find one without ridges in the fingers were the clutch plates ride.

I'm in with gggGary. It's the axle post/pin for the shift stopper, or the shifter claw-arm...

Hi and Welcome foureyes
We're not too far apart you and I .......I used to commute and work in the St Pauls district

I hope I don't find one of those when I remove my cover this weekend.
Will you be going to the annual Japfest at Haynes motor Museum Sparkford next month ?

Thanks everyone for the response!

I'm in the shed tonight so I'll take a look at the clutch rivets and the shifter pin.

Judging by gggGary's fine photography and the fact I'm getting false neutrals from 3rd to 4th I'm thinking it more likely the shifter issue.

More soon...

@Peanut - Hopefully I'm free on the 14th for Japfest - Never been but looks like a must see.
@fredintoon - Lots of Bedmo lingo going on here!

Update.

So I had a good look tonight at the clutch basket (all rivets present and correct) and the shift rocker as gggGary suggested.

The shift rocker pivot seems to be intact but it looks like the 'widget' is missing from the arm above??

Whilst looking I also noticed that only four of the five shift star arms has a rod behind. Is this normal?

I'm off to Yambits and Mikes now to see if I can find a replacement. I've got a couple of days with a spanners next week so trying to line things up for then.

@gggGary. My shift mech seems different to yours. Mine is a 82 Special USDM. I guess there are plenty of small differences through the years.

Cheers all!

Image of the shift rocker. I'll get used to this posting malarkey soon I hope.

See that arm on the left, the one with the spring attached to the top and a hole near the bottom? I'm pretty sure your "widget" goes in that hole .....

 

[gggGary]

Yes one rod on the star wheel should be "missing".

 

[gggGary]

Looks like you have a bit more digging around to do, I think the red circle is the widget that keeps the big wheel (green circle) on. You need to find your big wheel, I think getting that back in place that will cure the missing shifts. IIRC it keeps the the star wheel / shift shaft centered when the spring pushes it between the rods.

 

[foureyes]

Thanks 5Twins/gggGary.

Relieved to hear my star has the correct amount of rods

Here's the photo that I failed to upload last night.

As you can see my shift mech is a bit different from both of yours but it clearly shows the hole that the 'widget' belongs in. However I can't see anything behind that it would engage with though?

 

[peanut]

the widget is rivetted to the missing disk through the hole on the arm .It cannot be fixed to the the crankcase because the arm with the hole in it is free to move on its pivot fixing at the bottom and is held in place by the pressure of the spring at the top.
it will be clear once you have dismantled it.

That area stays the same (all parts interchange) for all the years 70-84 yours SHOULD (has to) look like our pics.

The part in question, I had one in the bins.



This won't be found new, it's used or nothing. I do have an extra one 2 oz. first class parcel but international takes a while. mailing is 6.50 USD so $15 USD to your door if that interests you.

Oops here's a new one!
