200t sprocket size

[humble arb]

Hi all.

 

Follwed this forum for donkeys, but first time posting.

 

Recently had my 200t pretty much rebuilt. Guy who carried out the work switched the sprocket from a 6 pin up to a 7, saying it would improve the performance of the saw. Will it?

Iv a 150 for all pruning works, so the 200t is 90% removals. I run a 14" bar for this reason, semi-chisel chain, saw is stock, no mods or porting.

 

Will the 7 pin improve its cutting through larger timber? Or am i better off switching it back?

I would say there’s more chance of it improving the saws performance on a 12” bar than a 14”, that’s the general rule of thumb though. Not actually tried in myself on a ms200

Got to agree, I reckon the 7 pin will rob the saw of torque on a 14" bar but may be faster on a 12" bar.

If you don't use the full bar length in the cut then it may work but my thinking is most climbers want a fast, non bogging precision cut and I would normally stick with a 6 pin.

I see. Think il switch it back then.

 

I know il need to fit a corresponding worm gear to match the sprocket, will i need to change anything else to do with the oiling system?

No, just the sprocket drum and the oiler pinion worm
