^ yeah I figured it would not be an enjoyable experience, the ruler picture would be much apreciated thanks.

ps, is it only the rail closest to the input that you grind?

Yes the rail closest to the input. I took pictures of both new JB rails here :

I hope this helps you.

FYI for any one else having issues...The Serenity setting for Board style cleared the problem up.

got mine done! thanks again Deo, those measurements worked perfect. I ended up checking those with ones I found on pirate 4x4.

final measurements I used (just grinding the short rail)
grind 3/8 of an inch off the end of the rail and 7/16 off of the middle part of the rail, keeping the same slope on both.

I also fully rebuilt my 205 with all new berings and seals, that was not as easy.
i was in a rush so putting it back together quickly turned into a "hurry the rtv is drying!" type situation. but after everything i got it done.

heres some pictures...

all the way down to a clean case...
Image

rebuilt and ready to go back in.... (I used the trans jack this time, sprianed my hand last time I tried to muscle it in witout :( )
Image

what I made my linkages out of: stock crossbar linkage cut in half and sleeved with a piece of tubing, worked well (and I can still get both linkages off while in the truck..they arnt pretty but again i rushed :roll: BTW the crossbar is made out of the stuff that wolveriens skeleton is made of, I must have ruined 15 drill bits trying to drill them out
Image
Image

and my crazy linkages.... I got the heims and threaded links premade from school, so even if they are massive and overly robust... they work well
Image

and of course... I had to throw a clear pto cover on.. funny thing was, once I had evberything hooked up I had an issue with selecting rear axle low, I could see that the synchro thing was not fully engaging on the output synchro so I know i had an issue, it was just a heim that needed some clearancing but...the cover helped me see that... kinda cool 8)
Image

I'm very happy with how it all came out, I found out there were some thrust washers in my mainshaft assembly (input/output) that were almost worn throught, it solved my 5th gear vibration that I was having...very happy about that. :grin:

the shifthing in and out of gears is very smooth and the detents are clearly felt (no searching for gears any more)... also like Deo said, you can slide rear axle/front axle in and out of gear at any time, but if course you cant put front in low and rear in high (or visa versa)

Deo,

yeah I got lazy painting stuff, hard to justify making stuff super nice when the truck itself is most accuratly described as a bucket of rot :;-|:

I got my seal kit and bearing kit from Zbag, it was a very complete kit but had the same issue as the last kit i bought from them... the front bearing support. adaptor (yeah the big one I didnt paint :lol: ) gasket is wrong, as it was on the last kit I had , I am guessing it was designed for the smaller input shaft/bearing.... funny thing is all the bearings were correct....

and yeah, i want to go to the u-bolt style as well, Zbag didnt carry the drilled out yoke and told me that "they" stopped selling the ubolt style straps... so I bought new strap style ones, I think the kit was 5$

i think advanced sells the straps...but i like giving my money to places like zbag, they have treated me right so far

I think drilling them out is simple, but i dont recall if the stock 1410 yokes have the flat surface behind so that a nut can propperly seat

Ahhhh, Zbag. The wonderful people who told me that when they rebuild a Getrag they never need anything other than .005 and .010 shims, so that's what they put in the shim kits. :roll:

^ yeah i wouldnt say their advice is top notch but the parts are good.

they told me when i was rebuilding my rag that i would not be needing the 5th gear synchro...because they dont go bad.... it was toast
