Hello
I have run into a problem with my Raptor Titan 50 SE. I am new to the hobby and this is my first build. I completed everything and was going to crank the motor to break it in. I bought the whole thing as a kit so it is the Redline 53. I feel like I must have done something wrong. The cooling fan screws onto the motor shaft clockwise. Then there is the nut, the the clutch with the oneway bearing. The engine has to turn counterclockwise to crank per oneway bearing. Since the moter is turning counter clockwise, and the cooling fan goes on clockwise. The cooling fan and the nut are backing off. This causes the cooling fan to bind against the frame above it and locks up the motor. HELP, what have I done wrong?
Thanks in Advance
Cody

You haven't gotten the assembly tight enough.

How did you put the fan on?Take the backplate off and stick a plastic toothbrush between the rod and block so the rod/piston won't move then put the fan on as tight as you can.Do the same with the nut that go's on top of the fan but put some red loctite on the crank.If you don't use loctite on the nut it will come loose.

Loctite isn't necessary to keep the fan from coming loose, you have to get it tight.

Thanks
Maybe I wasn't getting it tight enough. I have done what you suggested and really tightened down on it. It wont go no more. I'll put the engine back in and try it tomorrow. Thanks again.

Also make sure you leave the crank washer off also , Raptors do not require that .

You have to make sure the fan is tight first, then tighten the nut.

This is the ideal way

But this works

Either way, you want it tight, but dont gorilla it and break something. A crank lock is a good tool to have as well.

For me, It's not about locktite. Yes use some but IF the fan is not "jammed" against the nut, it will still come loose in time.

What you do is snug the fan down, then snug the nut down on it. THEN, back the fan off towards the nut really tight.
