Toplink brackets 1602D?

project_X · May 30, 2006

Hi all,
I am in the process of replacing the toplink brackets that attach to the back of my 1602D. I removed the bolts, but they were SAE (3/8), I suspect they must have been M10-1.5 or something. Does anybody know what they are supposed to be? I would like to fix the thread (as they are in rough shape, drill out and retap, or use a helicoil. Suggestions?

Cheers,
Rob

Helicoils were designed as a temporary fix, until a machine could be brought into a workshop and the hole either, oversized and retapped the next size, or welded and redrilled the origonal size.
Helicoils are only as good as the thread you screw them into.
Many years back during my apprenticeship in coal mines, we used then as a temp repair on machinery. They were forbidden to be used in bolts retaining covers on flameproof/explosionproof switchgear.
I personally haven't used them in years. I'd much prefer drilling and tapping to the next bolt size up, much better job and stronger too!

I had already decided to drill and retap to the next SAE size up. I don't really like the looks of the Helicoil, thanks for your response.

thanks,

They are good for what they were intended for Rob, a temp repair in the field, until a machine could be brought into a workshop for repairs.

I'm surprised you didn't stay with a metric thread! Keeps everthing neat and tidy!

Keeping it all metric would be great, but SAE taps and grade 8 bolts are much more acessible. As well, when I looked into it, I could remove much less material getting to the next SAE size over the next readily available metric.
