View Full Version : Right gears, Left gears

I have several questions about Right hand gears vs Left hand gears. I'm asking here on the forums because its a good place for info. Also, there is probably somebody else out there who is just as naive as I am. When do you use RH vs LH gears? Aren't all props cut to rotate in one direction? How do you orient yourself to determine which way your drive rotates? Do you see which way the top gear turns from the engines point of view? Or do you see which way it turns looking from the front of the v-drive? Or is it the lower gear you look at? Lots to learn............

I've run both types in mine and they work just fine, although I did get a little more whine when I ran the opposite??..BTW sangster, since when does a motor facing the wrong way, supposed to be the right way???... http://www.plauder-smilies.com/happy/roflmao.gif http://www.plauder-smilies.com/happy/roflmao.gif http://www.plauder-smilies.com/happy/roflmao.gif

If you drive off the flywheel you use LH gears. Off the balancer (roundy round style) you use RH.
Some roundy guys us LH gears anyway. Donno if I would do that myself.

Got It. My flat runs LH gears since the driveline comes off the flexplate (vib. damper to the rear). When buying gears do they come marked LH or RH? If not, how do you tell one from another??

A few other things to look for when getting gears is the angle. The 10 degrees are stamped as such. The 12 degrees do not have any markings for the angles. At least most don't.
And you CAN NOT mix and match from one set to another to get a different combanation.
Don't let people talk you into running 10 degree gears in a 12 degree box. They will fit in there but won't engage correctly. Lots of people do it but I feel it's a no no myself.

The easiest way I've found is with a simple protractor device you can buy cheap and a tool store. Or SD probably knows the case numbers. On props, looking at the prop from the back of the boat, if it rotates ccw (top blade to the left) is is LH prop, if it rotates CW (top blade to the right) is is a RH. Hope that helps.

The easiest way I have found is you put the unknown gears in, start it in gear or start it and throw it into gear or whatever you v-drive guys have to do. If you hit the gas and it hauls ass backwards, I think it's safe to say you have the wrong gears so paddle back to the beach and watch the jet boats play some more. :D :D :D :D
Sorry guys, just couldn't resist this opportunity.

8 degree = 60800
10 degree = 61000
12 degree = 62500

Fired UP, What Dave said is right. Heres a little more.
Any set of gears NOT stamped with degree are 12's.(because when they made the gears Casale only made 12 degree v-drives, so no need to stamp them.)(mid to late sixties)
Some 62500 cases are machined to be 10 Degree V-drives.(it will be stamped to the right side ,neer the top)
You don't want to put 12 Degree gears in a 10 Degree box because the teeth will not fully engage.(across the tooth) It will work but now you are only using half the tooth width.
As a rule, gear teeth don't care wich way they are turning.
In the case of a v-drive, the gears are trying to separate from each other, thats why the angle on the gear teeth,(one left hand ,one right hand) Make the pressure go in the direction you want.
Bottom line is you can use them either way and get away with it.
NEVER put 10 degree gears in a 12 degree box.
