To run dual cases with your V6, you will need to buy an adapter for your transmission to adapt to a gear driven transfer case to ithttps://www.marlincrawler.com/transfer-case/built-units/hilux-gear-drive/dual-case-unitthen buy/build your your dual cases using 23 spline input gears for both cases.https://www.marlincrawler.com/transfer-case/built-units/hilux-gear-drive/dual-case-completeAnother option would be to find a 5-speed and transfer case out of a 22re turbo truck, as the trans is an R series like the V6's, and the transfer case uses 23 spline input shaft from the factory, then you would only need to buy a 23 spline Crawler Box, but they are rare and pricey now.
I thought Marlin used to do adapter plates to use a 4cyl crawl box in front of the old 3.0 chaindrive but i dont see it on the site now. Maybe call.Otherwise you will need to build dual 23 spline gear drive case set with adapter for your r150.This is what I run behind my 3.4.
Thanks for the reply Snowtoy.1. When you say an adapter, you refer to an adapter that alters my transmission bolt pattern, but where can I buy that adapter?
2. When you say buy or build my dual cases with 23 spline, you gave me this link (https://www.marlincrawler.com/transfer-case/built-units/hilux-gear-drive/dual-case-complete), but that is for 4cyl and I have a v6 case, wouldn't this be the appropiate link (https://www.marlincrawler.com/transfer-case/dual-case/hilux-gear-drive-conversion/dual-case-complete) ? or, could I adapt a 4cyl duals cases to my R150F trans?
That is what I am thinking. The dual case complete for the V6 (Hilux_Dual_6cyl) has an aluminum adapter but that must be expensive. I thought that I could find something to bolt on with adapters like the MC10_UNIT so I could use my chain t/case.
If rock crawling isn't what you mainly do, then dual cases aren't really needed. What percentage of your wheeling is done in 4 Hi, and 4-Low? If mainly in 4-Hi, and you find 4-Low isn't low enough for your needs, you could go with a single gear driven case with 4.70 gears, and just the one adapter plate. The 4.7 gears will basically give you dual stock cases, which will help with controlling wheel speed for dry hill climbs and any of the larger rocks you are finding you have to hit at speed or stall out on on the trails you run. Of course, with the 4.7 single case, if/when you do use 4-Low now you are usually in 1st or 2nd gear, with the 4.7's you will likely use 4th-5th gear, unless needing to creep along.One trick that can help, if you have it, is kicking on the A/C, it will put enough drag on the engine while increasing the engine speed, to help reduce stall while trying to creep along, not so much for climbing onto a rock or ledge, but with descending them.
In a combination of 2.28 front case and 4.7 rear case, is it posible to use 90% of the time (around 3 hours of the trail) the front case in 2.28 LOW and the rear case in HI an only use the LOW LOW 10% percent of the time (when the trail gets really dificult)? I mean, Using just the front case in LOW and the rear in hig, for long periods of time, will it break the crawl box or wear it prematurely?
Yes you should be fine, the wear would be the same as if it was just a single case. Outside of being on the highway, I almost always run in low, prefer the lower torque for taking off with low psi in the tires, and for increased engine breaking for avoiding potholes/ruts on fire/logging roads.
So far, I will go with the dual case complete with 2.28 front and 4.7 rear. What I am thincking now is if I will go with twin sticks or not. The only benefit of twin sticks is 2 extra combinatios:-2WD 4.7-2WD 2.28*4.7both combinations won't be used at all (at least by me), so I think I will save $250 to $300.
Which type of stick do you have on your t/case SnowToy?
