My buddy was having troubles with his blue 2 1/2hp clone from Harbor Freight engine. So he decided to throw on a new Predator 99cc. Both are 5/8" shafts... The problem is that the new Predator shaft wont accept the same 5/8" 20 series driver. The shaft is a little bigger. We even went to HARBOR FREIGHT and checked the display model. Same thing. I don't know if it is the batch they have or if it is all the new 99cc engines that are NOT going to work. Anyone have a problem mounting a 5/8" clutch or torque converter on one? Randy
Harbor Freight 99cc Predator engine issue.
Apparently they are aware of this ISSUE. But he actually said the most people who go to Harbor Freight realize that not everything is up to spec AND the actual sizes can vary............ I mean really. We know it is cheap junk for the most part. But you shouldnt have to take it to be machined before you can use it.....
I have a 99cc,and the shaft is .630
and I bought a maxtorq 5/8" 11 tooth...the 5/8", is .625 I took the clutch apart and chucked it up in the lathe then ran an 16mm bit through the body of the clutch...I would not try to do this with a hand held drill motor(if you had one that would hold a 16mm bit) because of the keyway slot will tend to drift the bit off center and the hole will be out of round... By being in the lathe,it stays true and on center with no vibration on the engine(A good way to wallow out the sidecover bearings)....Scootercat....
