I’m ready to assemble the Orion that’s going behind the H41 (behind the stock Mercedes OM314) in my 88 OJ50 Bandeirante. With stock 3.70s and 33.9” 8.25R16s.
I specified fine spline rear output shaft. The current stock TC has 1.992 low range. Says so in owners manual. Not low enough with 3.7s (needed for 60mph though) especially with 34s instead of 32s.
I have a donor case in the garage with idler gear tooth counts 41/27. Parts book says that’s 7504-8007 time range.
Question is: is donor case 1.992 or 1.963? Does it even matter?Probably doesn’t matter, but I’d like to know for sure. AA doesn’t think it matters. I know for sure it’s not a 3 speed 2.313 case because those have 39/25 idler gear count.
It appears all I’ll need from the Bandeirante is the top high-low shifter cover, missing from the donor case. Also PTO cover of course.
After this (73:1 low 1st), install takeout rear Detroit/front ARB from defunct BJ60, fix broken LF spring leaf, install aux fuel tank (stock only 52L!!).
Etc.
