Link arm and link arm pin removal

#1 · June 28, 2014, 1:09 pm

Hello,

my name is Ranatra, I am a new member of this forum and I am writing here because I have an issue with my Dillon xl 650. I need to clean up my reloading press because it is all dirty and with some debriefs inside all the joints

I have tried to take off the two link arms (#14922) and link arm pins (#13700) but, after many attempts, I have failed in that operation. It seems that link arms and link arm pins are somehow cemented together.

To finish my cleaning operation I need to take off all these parts. I have attached you two pictures of my xl 650 to better explain what i need to know.

Thanking you in advance for your time.

The link arm pins have a shoulder to keep the link arms from being tightened up against the frame. Looking at your photos, if you can slide off the left link arm, you should be able to remove the right side link with both pins still attached to the link arm.

I have already tried to take off the left link arm with all my strength and with an hammer, but in vain. I was only able to slide asymmetrically one side of the link arm and make a 5 mm space between the frame and the upper link arm.

Is there a lock or a gasket to take off from the link arm pin?I can't really understand why it is so hard to remove this part of the reloading press.

If the pivot pins won't easily tap out towards the right, then there may be some galling on the pivot pins. Squirt some oil into the lube holes in the frame and link arms, pivot the crank to spread it around, then oil and pivot again. let it set a few hours for the oil to wick out to the dry areas, then try again using a hard plastic mallet.

Thank you Dillon, I have followed your advice, but link arms and link arm pins seem fixed altogether. Could be arms and pivots connected by shrink-fitting? Have I to heat up the link arm's ends to take it out?

I used a block of wood and a hammer to persuade the arms apart.......mine were very seized up as well took quite a bit of tapping ....I would not heat anything

Do not apply any heat. I strongly suspect metal transfer causing by galling is why they are difficult to remove. The block of wood and hammer advise is good.
