JD 6030 with Ind Planetaries July 22, 2012 02:27PM
Does anyone know the ratio increase when using 760 scraper planetaries in a Jd 6030?

Thank you

Its a lot! 48% I think. Do a search and I posted the ratios for diffrent gears with both industrial and ag finals.

what about 5010 industrial finals on a 5020? will that speed it up? if so how much? thanks

Re: JD 6030 with Ind Planetaries July 24, 2012 03:34AM
There are only 2 ratios of Big frame finals 3.36 and 5.0. I think the 3.36 is only on the scraper tractors and the 5010I would still be 5.0. Honestly you should use the factory finals and build gears for the trans if you need more speed. The fast finals cause the transmission components to be overstressed and to fail.

So what percentage over stock 8th gear and other gears be?


Thank you

Re: JD 6030 with Ind Planetaries July 24, 2012 01:57PM
with fast finals 7 th gear would be about 6 % slower than factory road gear. with fast finals you can only use 6th and 7th gear

How big a turbo to run 8th with that high final drive? Have a 4.25 and it can't do it

Re: JD 6030 with Ind Planetaries July 25, 2012 05:14AM
can't be done.

Re: JD 6030 with Ind Planetaries July 25, 2012 08:25AM
Two 4.1's feeding a 3.9 might get you enough torque to run 8th with industrial finals. :-)

Re: JD 6030 with Ind Planetaries July 25, 2012 10:16AM
OK I know we can't do that LOL Guess we will put the stock back in it.
Thanks for your comments

Again for the big block record I don't know the exact tooth counts, but these should be close on stock finals.
6030 stock 6th 49.5:1
6030 stock 7th 38.30:1
6030 stock 8th 23.36:1
6030 industrial 6th 33.26:1
6030 industrial 7th 25.73:1
6030 industrial 8th 15.7:1

Re: JD 6030 with Ind Planetaries July 27, 2012 01:24PM
Thank You KTA we switched it back to stock Planetaries will run 8th for now and maybe speed it up later with a new gear in another spot maybe a 21 or 20 ratio ????
