[Got 1800?]

is there a part number? something to indicate what it is on the outside housing or anywhere by just looking at it?

TIA

That would be tough. The only way I know of is to look at the gears. That's the only difference between the 13 & 18. I could be wrong...I hope so.

 

[Got 1800?]

so there are no markings on the outside to tell huh??

I haven't looked real close for any numbers. It's the same housing and shaft, just the gears are different. I don't know the calculations, but the # of turns of the shaft compared to the # of turns of the drive gear = the ratio. Once you know the ratio you can tell if it's a 13 or 18. Maybe one of the engineers will get on and help.

If you ask me real nice I'll tell you how to tell the differance. I do know how:bleh:

I'm just a little worried that people may start miss representing their drive if I let out how to tell. But I did tell Got 18 how to tell cause he's been askin' for awhile. If you ask him he may tell you how. I will be off the boards (all of them) for the next 10 days. Ya'll be safe see ya in ten.

Ok, I know mine is stock 1300 but now I'm curious. LOL. If you don't mind PMing me and letting me know how to tell, I'd appreciate it Got 1800.

I think the only way to tell is count the teeth on the ring gear, 31 teeth is a 1300 and I believe 33 teeth is an 1800.:hmm2:

I don't know what the #'s would be for a VTX, but we used to figure out gear ratio's in car axles by spinning the axle one full turn & counting how many times the pinion shaft went around. I'm sure the same system is used to know which one is which on these to.
