Drive Screw

gers31 · Post by **gers31** » Tue Apr 27, 2010 10:43 pm

I inherited a SS 510 and found that the Drive Screw on the Quill Feed Pinion has broken off with the head of the screw still on the spring. Being new to this do I have to order a new pinion and screw or can I have my machinist friend drill the screw from the pinion and replace it with an alternate screw? Just want to make sure I'm not missing something.

Thanks,

I do not understand what you are saying here? Is the screw shaft still in the pinion? If you could get the original screw out, you may be able to 'replace it. You will need the screw from ss.

A pix would help us understand!

Sorry, i didn't explain that very well. Anyway, the drive screw that is attached to the quill spring and feed pinion sheared off with the head of the screw in the spring and the rest of the screw flush in the pinion. Sorry I can't get a picture at this time but just wondering if I have to get a new feed pinion or am thinking that maybe the screw can be tapped out and replaced. I wasn't sure if I should be looking at replacing any other parts while it is apart.

Thanks,

I would believe you will have a problem find the right screw and if found, keeping the screw secure in the shaft. I did not have success replacing this broken screw myself. I find the Quill Feed Assembly are quite reasonable priced on Ebay (Item number: 110524604918). I have just the shaft with the screw that the spring broke if unable to find one. Contact me off-line. Thanks.

We have a small machine shop in our plant, if we're talking about the coiled spring for the quill advance, I drilled a matching hole on the other side and found a same-sized rivet (?) to reattach it to the quill shaft. Worked great, only required a drill press.

Like Bill says, complete quill advance assemblies are dirt cheap on eBay.

I had the same problem when I took apart my 54' Greenie the damn spring retaining screw had been snapped off. I just chucked it and got one off Fleabay. Much easier than trying to fix it and I love fixing things but this was just one of those things you look at and say screw it and get a new one.

Does this mean (145378) is not obtainable from ss?

Since it is 'driven' in rather than 'screwed' in, it would be preferable to drill at a slight offset distance from the original. The correct hole dimension is critical!!! Any proudness of the original screw(pin) should be eliminated.
