I was out of town for a week and knowing time was critical I had Rocky, who is our drivetrain specialist of 16 yrs, build my TacoBox with a set of our 4.70:1 Competition gears (made from Chromoly by Toyota's own gear cutter in Japan) that feature our Total-Spline technology (world's strongest Toyota input design).This also meant I missed the opportunity to get pics of the build. I do have studio pics for a 1st gen Tacoma which is nearly identical except for bolt patterns...This is our MC09 TacoBox with our new updated front & rear adapters. Click each thumbnail for larger resolution: We are looking at a 1979-95 Toyota High-Neutral-Low t/case section extracted and placed between two Marlin Crawler adapters ready to be mounted between your choice 1995.5+ transmission and transfer case.Described by location:Transmission --> TacoBox --> Transfer CaseDescribed by shift modes:Transmission --> H-N-L --> 2H-4H-4N-4LThe nice thing about duplicating the High-Neutral-Low section is that in High Range we have a 1:1 direct drive meaning that whatever torque we have entering the Marlin Crawler will be the same exiting (ignoring insignificant parasitic losses).New T/Case Gear choices become:1. Marlin Crawler in High, stock Tacoma t/case in High = 1.00:1 x 1.00:1 = 1:1 (cruise on highway same as factory)2. MC in High, Taco in Low = 1 x 2.57 = 2.57:1 (same as any other Tacoma on the trail)3. MC in Low, Taco in High = 4.70 x 1 = 4.70:1 (83% lower than stock!)4. MC in Low, Taco in Low = 4.70 x 2.57 = 12.08:1 (370% lower than stock!!!)When you replace the 1979-95 2.28:1 factory Toyota low range as I've done with our 4.70:1 ratio (which Marlin created in 1995), you have what we call a "TacoBox Supreme". Probably 95% of all TacoBoxes we build are Supremes. The primary reasons for this are 1) if you're going to do this much work why not go all out, and 2) with the Supreme you get three very distinct ratios (2.57:1 & 4.70:1 & their combined 12.08:1) instead of a similar pair of 2.28:1 & 2.57:1 which isn't nearly as interesting.There is one final part remaining and that is how do we get the smaller 23-spline automatic-type t/case input to connect to my manual transmission's larger 19-spline output and for this we designed a 19-to-23-spline coupler with an extended length specifically to match our Total Spline input technology. I'll update the thread with more info & pics of this once we get actual production couplers ready.
I've been trying to order this since November 2017.
The last Round-Up ended Sunday Sept 16, 2018, or 338 days ago, which was the last time I went wheeling This is the longest I've gone without wheeling since getting my driver's license. /firstworldproblems
Current Hilux has front e locker
WHAT DID YOU JUST SAY??Toyota of USA... plz kill me
Will there be any seal options with grease nipples for the helm joints / uniballs for ppl who live in colder salty climates and see lots of water.? I’m saying this due to my experience with them in Canada they only last about 3-6 months into winter or a few trips through water crossings and they are destroyed from all the sand/salt/backroads rocks and dust with super cold temps (-30 to -50c) They are much too expensive to have to change them out that regularly.
Have you attempted the soup bowl on the Rubicon? I'm curious if the modern Taco has enough frame clearance for obstacles like this.
