What gear do I need for these cranks for Briggs raptor? 2.737" 2.837"
Are you putting this in a flathead, or animal?Do I need a 26 teeth or a 29 teeth for a stroker?
Yes and no. Depending on the motor, the crank gears have different widths for the key.Why can't you just count the number of teeth, the ratio has to be 2 – 1............. right?
And if you went through enough of them, you'd find the ones with the casting parting lines that were offset....I'll let you use your imagination from there.Yes and no. Depending on the motor, the crank gears have different widths for the key.
As an aside, for my personal motors I used to go through the lawnmower boneyards for the old 202 crankshafts with the fixed gear, and chuck the crankshaft in a lathe, using wet/dry sandpaper to clearance a slip fit for the sidecover bearing.
Most of them had rod material melted onto the rod journal, so muriatic acid would be needed to to clean the aluminum off. But the journals were so hard on those old fixed gear cranks that wear was never a problem. And the gear NEVER broke.
Still got a box of them in storage somewhere.
