NGC found bolt on my driveway NGC

[fotoguzzi]

this could be a belt guide pin?   





found on driveway just after mowing my lawn..it has anti seize on it. I can't see anywhere it could have come loose from tho.. just on a long shot maybe one of you can provide guidance.

     Looks like the jesus pin that holds the differential gears in place on a vehicle rear end.

[Chuck in Indiana]

C'mon, Brad.. if it has antiseize on it, you put it on there.  It's probably one of those short term memory things.. don't ask me how I know..

[pehayes]

Looks like a brake caliper bolt/pin.  Any brake work recently?  Presence of the mower may be a red herring.    What else has been parked/driven over that spot?  That lip also makes it look like it was supposed to have an o-ring on it below the threads.  Can you measure to determine if the head hex is SAE or Metric?

Looks like a henway detent.

[Kent in Upstate NY]

 A bolt that attaches the mower spindle  to the deck.

Not heavy enough ....

Dikfer spindle?

this not my model but looks like item 54?
tried to see inside that area but can't with the body work on.
and the drawing is hard to visualize where they actually go.

 



Lot of rain came, grass ready for another cut but I haven't had any time to tear into it.

I'm with Patrick...that looks like a brake caliper pin.

[Noguzznoglory]

looks like a brake caliper bolt/slide pin to me as well

[Wayne Orwig]

Brake caliper pin.
The ridge around there is to hold the rubber 'accordion' boot to help seal the pin.

[Sasquatch Jim]

I have no doubt, it is a thornorkin bolt.

I haven't done a top ten list in a while, so here it is:

TOP TEN THINGS THAT IT IS:

10    idle mix screw for a donkey engine
09    PTO coupler grunge pin
08    skateboard axle
07    Shear pin off a 747 turbine
06    Trigger pivot pin from a punt gun (look it up)
05    what the "sacred screw" looks like with its vestments off
04    upgraded Stelvio fork pinch bolt (can't overtighten)
03    the reason why all those navy boats are running into other boats (give it BACK!)
02    throttle stop for one of those V8-powered trikes
01    Guitar truss adjuster

If you can't find an answer you like in the list, then there's something wrong with you.

I like #03


my Subaru shop says it looks like a Toyota part but it's not from my company Rav..I need to look under my Camry tonight.

[normzone]

Your Toyota shop will tell you it looks like a Subaru part.

You know what the guys at the Harley shop are going to say.

[Dukedesmo]

I agree it looks like a (car) brake caliper slide bolt. In use there would be a rubber gaiter (probably packed with anti-seize) over the threaded portion which would explain the grease.


I'd be carefully checking any car that was recently parked there.

[Kiwi_Roy]

It's not a Guzzi part, the measurement would be metric not inches.

" It's not a Guzzi part, the measurement would be metric not inches. "

Yeah, but somebody with rudimentary skills could fix that in photoshop.

caliper bolt go take a look at your car or who ever been in your driveway caliper ready to come out

If it is a caliper bolt, it is NOT one that holds the caliper into position so there shouldn't be any risk of caliper loss.  The mounting bolts would be far more robust.  However, such a bolt/pin would  be used to hold the brake pads into the caliper.  Absent that pin, the pads are going to launch out quite easily, followed by the pucks, and some quantity of brake fluid.  I don't think either condition is going to end well.

Meanwhile, looking back at the mower parts explosion diagram, this bolt/pin sure does look like that #54 piece.  Maybe  you're lucky and its just the mower part.  However, since the results could be catastrophic, I'd suggest your highest priority would be an inspection of any car or moto that had parked here recently.

the bolt is too big to be from the mower since I can see the two front ones under the engine, same part # as 54, they are smaller.. and the mower works fine, just did the yard.
Checked my Subi and the similar pins are smaller on it so I took my work var (ToyotaRav) into the shop where they confirmed no missing parts.. and replaced two calipers and a rotor, one was sticking. $800. the company paid..
then came home and crawled under my Camry, all present and smaller too..

all the calipers I've looked at are covered in road grime and rust but the found pin is pretty clean and not rusty at all. so I've checked all the vehicles that I have and none are missing a pin.. I agree it's some kind of brake pin but can't figure out where it came from.. I AM PISSED!  this really bothers me that I can't find where it came from.. no one was around to be playing a joke on me...
bolt has a large L and smaller T on the head.. anyone know of a bolt registry where I can identify it?

should I try to find out if it's a metric thread?



did I mention this is gonna bother me for awhile..

[rodekyll]

I don't see where you gave the dimensions of the bolt.

[fotoguzzi]

thread is metric (fine?) and it takes a 14mm hex on the head, about 3" long.

[pehayes]

Has anyone else parked there?
What is that purple stain on the hex head?  That might be a clue to vehicle brand application.  And so clean.  Must be a new vehicle of some sort.  Friends?  Neighbors?  Delivery trucks?
I doubt you will have to worry about this for very long.

When a major component falls off or a component fails you will know where it came from. I wouldnt worry about it....
It may have been lying in the street and a passing car shot it into your driveway.

[fotoguzzi]

or, fell from the sky. I live near MSP but they don't usually fly over me.

[Dofin]

looks like the bolt that a tention spring hooks up to on your lawn mower.  Photoguzzi is on the right track with the drawing he posted.

[rodekyll]

Could it be a belt tensioner from a drill press or table sander?
