62's have the larger idler shaft, but the shifting mechanism and shift forks are different.sl33py said:Thanks Mike and Jim.
so the 62's have the 38mm idle shaft as well?
what does a t/c rebuild cost?
food for thought - thanks guys!
That is what I have found in all USA market 34mm cases.GulfShoresFJ60 said:I have been rebuilding my transfer case and wanted to figure out the gear ratio. The input has 34 teeth, high sided of idler is 45 teeth, low side of idler is 25 teeth, high output gear is 34 teeth, and low output gear is 43 teeth. According to cruiserbrett the way to find the ratio is (high ilder/input)X(low output/low idler). Well doing the math: (45/34)x(43/25) = 2.276.
All this is to say this, I have an December of 1983 FJ60 with the 34mm idler shaft, so from the research I've done, most of the pre-85 US FJ60's have the 2.276 transfer case ratio.
A440 auto tranny have the 2.48 LR 38mm shaft ..FJ40Jim said:That is what I have found in all USA market 34mm cases.
I've rebuilt one late '84 H55 case w/ 1.99 ratio and 34mm shaft.
Does anybody have a tooth count on a USA 38mm t-case for H42 and for A440 auto?
We know that there is a different ratio w/ the USA 38mm cases. The parts fiche identifies *some* of the T-case gears by tooth count, and they are different for the two cases. Unfortunately, the fiche doesn't call out tooth count on every gear in the t-case, so we can't just calculate ratios that way.NocalFJ60 said:This is what Marlin said:
-USA 4 speeds all have a 2.28:1 low range
-H55F 5 speeds have a 1.99:m low range
-All 60's have the same 2.28 ratio behind the H42 4 speed
This seems to jive with what Jim is saying. Sounds like they went to a 38mm but keep the ratios the same.
Yes-but the shifter is different and needs to match the tranny. So if you have an 85, and want to use an 83 t-case, use the 85 t-case shifter linkage. As someone mentioned, all the USA FJ60 trannys were H42s.Kavik said:So, other than internal differences (i.e. 34mm vs 38mm idler shaft, and possibly different ratios) they are interchangeable and will bolt up to any US FJ60 81 thru 87?
