Could be a trouble free set up, I had a DM once with a 285 and 12spd with 4.17,s and the engine would run to 2300 RPM,s, it was a real sleeper!! terry

A price up front will weed out a lot of responses. terry
-
Not a bad price for all that work that has been done, if your into that kind of conversion. terry

Right behind fill plug on left side is a flat area, scrape with a putty knife then a wire brush, there will be a TRT72 or 720, that will tell what front box is, back box is always a overdrive on a triplex or quad. terry Also a aluminum back box will be a TRTL series
-
I would go with about a 5.13 ratio, is your triplex a single or double over? terry
-
Just checked one of my old manuals 1969 version that exact model no. was TRDXL107 for the low hole one and a TRDXL1070 for the overdrive one. terry

X107A is a six speed with air operated back box, a true twelve spd is 3 boxes all bolted together, a real long trans. terry

When they went to the 107X, reverse was put on aux. stick, then you had 5spds. in reverse along with direct and a low gear, also 1071X had a lower low gear in the aux. terry

no it was as I described above, It was before the X107 six spd, only made for a couple of years, I will dig in one of my old mack service manuals to check, If I remember it had an interlock to use the low range with the main in 1 st gear, and the overdrive one had to have the main in 5th gear. terry
-
if I am not mistaken that was the first version 6 spd, you shifted the main 5 times and the aux. box from direct to overdrive for the earlier deeper rear ratios, they also had one the aux. went from direct to low, for a lower first gear. terry

1989 Mack RB
terry replied to j hancock's topic in Antique and Classic Mack Trucks General Discussion
drove one of the for years ,not a bad truck at all, the front spring is longer than a regular R model, lets it ride a little smoother on the steer axle. terry -
There are wider spacers available, also used to use some add on spacers if you needed just a little spacing, don't remember what they were called, about 1/8 or 3/16 thick, they slid on right on with original spacer. terry
