To be slightly more specific: a taller one

[Sean H]

Well said Stan....

Since the gears are interchangeable. It could be taller and shorter.

But definetely different.Since we don't know for sure what it is now.

[E Dock DD]

I called Tyson and he said they are a 39 and a 41 and it is set for the taller ratio. He changed it from the short gear ratio to the taller gear ratio.

Yep, that's what I said in post #38.

He thinks he remembers the tooth count, but that doesn't tell us the final drive ratio. There are more that two gears involved.

And the reason he needs a Different set. Probably in the 1.24 range.

[E Dock DD]

I am assuming that you would change the 41 and 39 gears and not the other gears, and if you changed them to a 42 and a 38, you would increase the overall ratio around 5%. Do you know how much you want to change the overal ratio? A change to a 43 gear and a 37 gear would be around 10 to 11%.

Someone please correct me if they think I am wrong and know how it works. I have not seen how this gearbox is set up and how you can change the ratios.

What pitch prop does Delo have?

[OU Want Some?!!]

1.21, 1.22,... whatever it takes.

[GENERAL LEE]

1.21, 1.22,... whatever it takes.

"Want a beer?"

"It's six o'clock in the morning...."

"Scotch?"

[OldSchool]

ummmm.... a different one...

LMAO!!!

[Sea-Dated]

1.21, 1.22,... whatever it takes.

What's your vector Victor?

lmao, i still picture him with the cold beer against his head at 9 am...

That was a classic. 2 1/2 Months and we can do it again.

with a 39/41 gear setup you can have either a 1.227 or 1.356

swap the 41 for a 40 and you can have either a 1.257 or 1.324

a 40/40 setup is the gearboxes natural 1.290

Thanks big daddy. I talked to Myrik and he said the same thing. Looks like our slip is a little high. Need to find bigger diameter wheel or he suggested less rack. Frosty's might be just right.

[Sean H]

what rake and diameter are the 38's on there now?

[44MTI]

16.8, 20*
Their mine. I run about 10% and on Delo their at about 15%.

[Sean H]

surface drives and the wider tunnel allowing more blade area into the tunnel with that diameter is probably the slip increase... that and probably not quite enough gear.

too bad I didn't know 2 weeks ago, I would of brought back from kw the 16.25/16*/40's that we never use that are just sitting in the back of the truck.

we at least have the gear issue solved.
