Dog bone pin, replacement

[javi83]

Hello, I recently noticed that the pins on the dog bones have worn out wanted to see if I could just buy the bin and press them in instead of buying a whole new dog bone.

These are the ones you need. I changed mine around 5-6 months ago and still holding up great. The stock ones are little tuff to take off but nothing too bad. Make sure to insert the new pins from the rounded chambered side.

I've never known anyone to swap pins in 5ive t dog bones so this would be the first.

Bones are cheap enough to buy. I wouldn’t bother.

That's awesome! Glad it worked for you.

I will add this as a sticky to the 5ive-t sub forum.

Nice job on that @niz55

Can’t find them that’s the reason for the whole conversation.

how did u press them out?

 

[Rep732]

@Darnell if you go back through the replies I gave you a lengthy how to. Use a black impact socket to rest the ball of the dog bone on and press the pin itself

Yes sir I read them, I thought another person replaced the pins and was wondering if the had a different method, just try to gather as much information as possible, I have ordered the the pins.

Unfortunately there's no other way as your pressing a hardened pin into a hardened dog bone. One thing you can do to help you is freeze the pins before installing them as well as putting the dog bones in the oven at say 300 degrees. It will help to expand the dog bone and shrink the pin. I don't think 300 degrees is going to mess with the temper of the bone.

No 300 degrees won’t hurt anything. We heat and freeze parts all the time to help assembling parts with interference fit. Wrap them in a piece of foil and toss them in toaster oven. Freeze the pins. Make sure you have all your tools out. You need to try and work quick

EDIT: 300 degrees , this is "F" and NOT "C".

I used a hammer and vice to pull the pin out. However, you need to do it very well.
