[QUOTE="1TONZR2, post: 77594, member: 36"] As many of you know, I managed to tear up 2 different NP231s at Harlan last month, so I am tired of just do some things to just get it goin again....time to make it BEEF so I decided to keep part of my 231 and build a doubler. I love the low gearing I had, but wish there was a middle ground sometimes, well here is my plan first off, call Duffy at D.D. Machine (pirate vendor) and order this... NP231/NP205 doubler kit from D.D. Machine new seals/gaskets for the NP205 from Northwestfab.com new billet bearing retainers for the 205 from Northwestfab.com second half of my doubler....I will have 1:1, 2:1, 2.72:1, and 5.44:1...plenty of gearing for sure! The 205 uses a 32 spline input and 32 spline outputs. I did a little horse trading with HAD on pirate and got some 1410 yokes for the 205.... [ATTACH=full]146223[/ATTACH] [ATTACH=full]146224[/ATTACH] [ATTACH=full]146225[/ATTACH] also had to buy a new input gear for the 231, since the one from the second tcase was actually too short and didnt know it until I tore it back apart. no damage to the trans output which is a good thing... [IMG]http://i73.photobucket.com/albums/i226/big96zr2/DSC_0034.jpg[/IMG] one on the left is the 2nd 231 input, middle one was from the 4:1 kit and the one on the right is the new one...gives me more spline engagement, which makes me happy... Also have a 6 pinion planetary set coming for the 231, the 3 pinion I had was actually broke from the shock load of the main shaft breaking...no since in putting one of those back in..... [IMG]http://i178.photobucket.com/albums/w253/Big91RustyBucket/1123080744.jpg[/IMG] [ATTACH=full]146226[/ATTACH] [ATTACH=full]146227[/ATTACH] [ATTACH=full]146228[/ATTACH] [ATTACH=full]146229[/ATTACH] [ATTACH=full]146230[/ATTACH] no pics of the cases on the floor yet, forgot to do that the other day before I stuff it in the truck to mock it up so I can start dealing the shifter issues that the 231/205 has. I will go into more detail when I start that. I am also picked up a 14B rear today. already geared to 5.13s and has an Eaton Posi unit in it..NOT a gov lock 140 bux, needs a couple of bearings... [ATTACH=full]146231[/ATTACH] [ATTACH=full]146232[/ATTACH] I am going to be doin some cage work inside the cab and prolly some sort of roll bar setup in the bed, going to try and keep the bed...just narrow it and bob.
