Title: Gear drive 10 10 Mac
Post by: Cut4fun . on September 12, 2015, 04:46:32 pm

While the ebay parts seller was here getting 3 saws from me. He told me he had about 600 saws and one of them is a McCulloch 10 10 gear drive. Mac 70 something ?  Anyone got info so I can learn about this.

I can get you  his ebay seller info.  He said is had the number 70 in it from what I can recall.  Hmmm KP outdoors comes to mind off hand.

I know about the electric starts but didnt ask. Was a neat idea back in the day.

That saw is likely a G70.  There were a number of 54-70cc 10-series gear drives.

I have a 5-10G plus a parts saw and a partial carcass.  Will build a nice runner out of the lot at some point.  There are many saws ahead of it in the project line.  IIRC, it had a 32" or so bar and a loop of 1/2" on it when I got it.

The only reason I can possibley think of for running reduction on a 10 series saw is possibley a lighter weight saw that could handle longer bars .

It would make sense for example how a 700 would have more RPMs than say an 80 or 87 c cc reed engine but it certainly would not have the torque of a reeder .

That was 650 which is 87 cc .That engine runs at over 9,000 under load and it's a two to one reduction .It's dandy but heavy as lead .

Sounds like a 7-10 with a gearbox the G-70 out here in Australia the railways used them on bridge construction
