Gearmatic 8a

Post by nwlogger » Tue Dec 24, 2019 2:41 pm

Hello all,
I am new to using online forums but I am looking for a part for a gearmatic 8a mounted on a 1010.
The part I am looking for is the cast piece on the clutch side that the little slave cylinder presses into. Please let me know if anyone has one available. I have a 40,420, and 1010 that I use for small logging projects and basically just enjoy keeping mechanically sound original condition.
Thank you, Jeff

Are you missing one or is it broken? It can be welded but it has to cool slowly by covering the casting completely in a bucket of sand after it’s welded. I think I preheated my casting first with a rosebud torch. I have a few parts leftover I’ll take a look if I have one.

Notmeu,
Thank you for reply! The one I have is broken in about three pieces unfortunately. I would take one with a crack in it for sure, I am savvy with welding cast parts. Thanks again!

Unfortunately I only have a leftover spider casting that I want to keep. There’s parts out there, I had to buy 2 winch’s to make 1 working winch.... check out the parts for a modern gearmatic winch. I found that there are parts that are used off of the 8a that are still used on modern winches. Checkout part #51627 it looks similar. You could always contact gearmatic and they can give you drawings to see if it is the same. I was able to get them to send me drawings at one time.

Thank you for checking! I have rebuilt a few of these little drums but have never had this particular piece broken. I will check out that number.
