Plow Index Pin

[Achto 28,082]

Have a broken index pin on a snow plow with part of it missing. Just wondering if anyone might happen to have the dimensions for one of these so I can make a new one.

 

Yes I see that I can order a new one & have it in a few days, but with dimensions I could have it made in 30min. 

 

Thanks

I have one here buried in a snow bank ... take me an hour to shovel  it out.  Also be one on the 502 plow I can measure.

Betting others are going to beat me to it!

@Achto  , that dry pin , wear area , about half way , is also showing you , a hang up . also lever rod  area , that entire quadrant motion area , should move with total ease , from lever point to , spring / pin slide point . like red aerosol grease , also lever / rod swing points . firming up , lever action , washers , and an elastic lock nut, to hold perfect bolt tension point , lubrication , makes that set up move with total ease . pete

While I agree with the lack of lube. I think this was just a plain old case of some one hitting something with the out side edge of the plow, causing the pin to sheer at it's weakest point. (where the hole is drilled for the cotter pin)

I don't have a pin to measure, but it looks like the pin length has to be 6.5" to engage the sector hole.

[Ed Kennell 39,532]

Just thinking the missing piece may be laying inside the frame or stuck in the sector hole.

Mine measures about that too. Hole for wire back to the handle is about a 1/4" from the end. Can't tell where the other hole is without taking it apart but should be able to gauge that by the length of the spring. 

Did you lose the spring too?

Too cold out Greasy... lube wouldn't come out of the can....

Just needed the over all length. Can pick up the hole spacing from what's left of the old pin. Still have the spring.

@WHX??  did an oil change yesterday , heater on in shed , 5-30 Castrol / 4 oz. of RISLONE zinc . perfect winter combo .  operational , quick start and running ease , also that 5 wt.  bottom start , warms up faster , and transition to 30 wt. is running ease , aerosol lube , was on the job , staying greasy , Pete

I'd go with 6 3/4 then can always bob it down if needed.

Think I would make it 1" longer than the broken pin.     Should allow enough to taper the end and still have 3/4" of good round pin in the sector holes.

Not to "Guild the Lily" as @Handy Don has accused me of - many times - how about adding a couple of shallow grooves to hold grease in the contact area?? Poor man's bearing!

Kind of like I did on the lower end of the 502 steering wheel shaft....

Get right on that Bill next time I have the mill spinning... oh that's right I don't have a milling machine... 

Not a bad idea tho but me thinks @Handy Don might be right... 

I suppose a guy could do it with a die grinder and steady hands ....oops i dont have steady hands either. 

I might try it when I set the 701 up for a moon shot or Titanic dive...

Gets too long may not be able to back it out of the sector. Guy could put some extra holes in for the rod. Have some adjustability then. 

 

How did you break that anyway Dan? Not really alot of back and forth stress on it. Hit a power transformer again?!?!?

Good point Jim.  So, I just went and measured mine.   I had exactly 3/4" of pin travel, so the length below the cotter pin would have to be less than 3/4".

Guilty  (and a mite envious of someone with a lathe and a milling machine and the skills to use both).

 

I also warn neighbors that borrow my pressure washer that any children in the home should be out of sight when they use it. Why? Because with the wand in hand EVERYTHING starts to look like it needs cleaning.

Weren't me. Buddy hooked some landscaping timbers with his.

Two things Uncle Jim, kiss my wife? huh.

Yep on the tape measure. 

 

The other is when I did my off shore engineering, I used a pin diameter of 3/4 and now I know now it is 5/8"..... threw off all the dimensions.  My bad!

That's why most most guys have 10 on them............Tape measures I mean!

Dan,  let me tell you getting a replacement pin is thr easiest part of this project!

I had one of these pins break from rust corrosi kinds looked like one you posted.

 

The brain surgeon might be able to do this on the fly but everyone else needs prepped.

 

I recall needle nose pliers, regular pliers, a nail or punch to set in pin hole and a good light .

 

the chrome cap over the pin hole must be removed.

 

On a side note throwing grease down this pin hole cover once a year or every two  years helps prevent.

 

The process has to go in a sequence and I wish I could Romberg exactly Dan.  
 

This is the part of the note that everyone wonders what to do next.

 

 

Take a good look at that plow drawing.

 

The  1961 and 1962 snowplows did have a leg up on the pin issue.  You could access the need parts for repair.

BUT - only 3 positions - no mid travel...

He's working on the later style Lane. Might not have those issues. 

BTW best you remove them HLs and send them to me for safekeeping. Wouldn't want to see you stuff it in a snow bank and bust one.
