Rear Blade Bent pins

[Tvanharp]

Wow - you did seem to get the perfect combination of immovable object at the worst possible contact location. I have an almost identiucal 7' BB from King Kutter. It's actually a medium duty blade. Their 7' HD weighs considerably more. I tweeked the lower 3pt pins on mine plowing snow, last Winter. "Oh, that's where the rock is!" I hit it square in the center of the blde, going backwards. Looks like you are using a cot off tire iron for an index pin, or is that what came with the blade?

Well I bent the index pin it came with bought another bent it then just found a piece of 3/4" scrap from an old wrench in my shop and used that. So no it didn't come with it.

Now that you've remedied the torn hole issue, I now have a suggestion as to how to prevent it from happening again. Get two Cat0 shorty lift pins and two 3/16" lynch pins. Use them as index pins instead of bolts. They're a full unthreaded 3/4" AND are hardened steel. They'll neither bend, nor pose a tearing potential to the index holes.

When you fix it, include a big outside diameter steel spacer between the swivel plate and the box section so the spacer will take the load as soon as the pivot flexes. This should make it considerably harder to bend the pivot.

Got a present in the mail today. New pivot assembly for my blade. I'll be more careful now....

Do what I said or buy more.

OK so I finally got around to fixing this. What I ended up doing was extending the main arm and added a plate that rides against the pivot assembly and also added a spacer under the main arm that rides against the opposite side of the indexing plate, and added a plate to the underside for the index pin. Also drilled a hole to accept a second index pin on the back where the main arm was extended. This basically does the job of the spacer between the pivot and arm.
Was using a Lincoln 225 amp AC welder with 7018 1/8 rods running at 150 or 135 amps.
Thanks for all the help!
