Thread: Chevalier FSG 618 Surface Grinder hub puller

Thanks Doug.
Yes mine has definitely had the blue striped apron treatment previously.
I’ll check it properly before I come to making the puller. I couldn’t see any likely imperial threads in the thread charts around the same dimensions as mine, but you never know.

As a result of the help on this forum I have successfully made a puller for the hub. Attached below is a couple of photos which may be of assistance to someone else.

As a bonus the hub turned out to have static balance weights in the back which is certainly a lot safer than drilling holes in the grinding wheel as advocted in many online videos.

Anyone know of a supplier of these hub in Australia?

Hello to Doug.
Surface grinder wheels over 150mm diameter may be balanced by grit blasting on the side of the wheel. It looks like a pimple. If you dress this out it may be difficult to balance the wheel. Also the wheel may have a radial painted stripe, usually black. This is the heavy side and goes to the top when mounting on the hub. Any hub to wheel clearance allows the wheel to drop a fraction and improves the balance.

Nice work on the puller Doug - and the balance weighted hub is definitely a bonus!

I just made up the hub puller for my Herless 618 that I posted the photos of earlier.
Confirming that I used a M25x1.5 thread and it worked fine.
