Doubler Stuff
I am building a low range gear box from a NP242, since I like to be different and not spend much money being different it is all home brew stuff (easier since I work at a machine shop...)
It goes to a NP 202 divorced case so I am using a double cardan "H" block and OEM slip yoke as the worlds shortest driveline..
None the less here is what I have so far:
I basically cut the front output off the box and sealed it with a piece of angle, I appologize for some of the goober welds - I had first welded this with a stick welder (weldanator) on the XJ - not a good plan...
It took a bunch of scary machining to get all the crap weld out of there - including hucking the case out of the vise once (the track marks in the corner
) Some time with the TIG machine and life got better
Once that was done the rear bearing retainer had to be modified to fit in a piece of tube that will get welded to the main cover plate...
I cut the shifter plate and rail down to just what I needed and made another slider for the rail; which mounts to the main cover plate...
So on to the shaft - I have a while back some one I knew weld up the shaft in the upper half of these pics - unfortunately they did not pay much attention to concentricity or runout - it is OK for mock up but otherwise is scrap...
Because the shaft has a slider sleeve I needed to shim it out for welding - I turned the shaft back (the stuff defines hard to machine) and begane turning the locator plug for the slip yoke splines.
After boring the slider sleeve and shim I heat shrunk the outer ring onto the shaft... I still need to press in the slip yoke spline and weld that stuff up but you get the idea...
A few bearing, seals, and some more 4043 rod and we should have a working box - all for ~150$ total...
