Using a Starter to verify Dual Case Load Reduction

In this video we demonstrate how much load is being reduced on the drive train by engaging our Marlin Crawler Dual Case Transfer Case System.
Comparisons shown are:
Stock Low Range (2.28:1)
Marlin Crawler Stock Dual Case (2.28:1 x 2.28:1 = 5.20:1)
Marlin Crawler Dual Ultimate (2.28:1 x 4.70:1 = 10.72:1)
For vehicles with start-cancel bypasses, having the Starter function so effortlessly on incredibly steep climbs is just another way the Marlin Crawler adds Control and Security to the driver and truck. You no longer have to disengage gears and trust the brakes to hold you while cranking: You let the Marlin Crawler do the work from the comfort and control of the driver seat!
We manufacture Dual Transfer Case Setups for most 1979 and newer Toyota 4WD trucks and SUVs including Automatic, Manual, Carbureted, Fuel Injected, 4cyl, 6cyl, and 8cyl applications.
To see some historical photos of the World Famous 1980 "Crawler Truck", please see our Vintage Photo Gallery here: www.marlincrawler.com/vintage
The Crawler Truck has a 2.7-liter 4cyl Tacoma 3RZ-FE smog-legal Engine conversion with a Triple Ultimate Marlin Crawler Transfer Case setup resulting in a 1,148:1 final drive / Crawl Ratio.

[@trailrunnah8886]

I've always thought manuals would suck on the trail due to stalling all the time, but this looks like it would make having a manual not suck!

[@MarlinCrawlerMedia]

Hello Michael and thank you for the question. When you understand that exactly no good Toyota automatics were available at the time Marlin founded the hobby of Rock Crawling in 1994, 100% of the first-ever Rock Crawling vehicles on the trails were manual. In fact, we did not manufacture the world's first Automatic Rock Crawler until the early 2000s (this first automatic test vehicle was a white 3.0-liter 2nd gen Toyota 4Runner). So for nearly the first decade after we created Rock Crawling, precisely zero were automatics. Marlin Crawler without dispute built the industry of Rock Crawling with manual transmission-equipped Toyota trucks. It isn't that Autos are not good for Rock Crawling, but rather the Toyota trucks of the era when we started Rock Crawling were faaar more rugged and less civilized than they are today. We would argue that if it wasn't for Toyota's weak (in the literal sense) marketing of sand (yuck) and mud (yuck) use with only featuring automatic trucks then we would have more manual-equipped modern trucks off-road. Case in point with BigMike's new 3rd gen Tacoma: It took him 8-dealerships, 261-days, and a flight to Texas all because he ordered a new manual transmission Tacoma. Feel free to read his full "Mega post" struggle with Toyota at the 16th reply of his build thread here: www.marlincrawler.com/bm2 TL;DR Marlin founded Rock Crawling with manual transmissions, and automatics only rose to popularity because of Toyota's relentless push to encourage the use of them here in America.

[@prismatic9804]

I use my rig as a DD so I'm enjoying the automatic of the 3rd gen 4runner :D

[@trailrunnah8886]

MarlinCrawlerMedia Thanks for the great explanation. I have a background with domestic 4x4s, and all have been autos. Good point about early Toys not having a suitable auto. I base my opinion of them on seeing (mainly Jeeps) in person and in videos bouncing and crashing over things. Seems like the pattern is bounce, stall, roll back, repeat. Doesn't look fun, and looks very hard on equipment, especially when frustration kicks in and more skinny pedal is applied. I'm sure most of the ones I've seen have been horribly undergeared, with questionable drivers. I'm a lowsy stick driver, and I bet your gearbox would make even ME look good!

[@MarlinCrawlerMedia]

All your view points and opinions are spot-on. Given two vehicles with the same final drive ratio, one auto one manual, it will be more difficult on both the driver and the vehicle for the manual. Gearing makes all the difference and allows for more torque at a smooth and quiet idle. If you have already, then please check out our gear ratio comparison video with clutch and brake foot camera view: kzbin.info/www/bejne/jaO1c5Wea5KYfbc Thanks!

[@evanch123456]

All Toyota knew for a long time we're manuals. When they switched over to auto the struggle was real. Overheating issues and fluid breakdown issues. Yes it also comes down to maintenance but all Toyota knew and built we're manuals at the time. The clutch start cancel was pretty badass. It made life easier. I used to avoid auto Toyotas but they have come a long way and all is good now. Keep your fluid cool and clean.

It wouldn't be uncommon for it to have a dry sump oil system. It's a system that doesnt have an oil pan, but rather an entire bled off oil system with no air in it. So it doesn't matter the angle, g force etc. Everything will always be lubricated.

i think the springs are designed for extreme wheel travel. most of the pack can drop, while a single, lighter leaf connects the axle to the truck. never seen one like it, but it makes sense when you think about it.

I don't understand how the starter motor can make the vehicle move forward? How does that happen?

[@MarlinCrawlerMedia]

Thank you for the comment. While manual transmission vehicles come equipped with a Clutch Start Cancel button, many of us bypass this entirely so we can always start the vehicle in gear regardless of the circumstance. Such is the case with The Crawler Truck. It could be cranked in reverse or even in 5th gear, for example, however without the torque multiplication of our Crawler products it would never have enough torque to overcome the weight of the vehicle.

[@JohnHenkamGangte]

So this started to get a better high and low range, correct.. I'm guessing that 4.11 in high and 5.38 in low..

This is an additional gear for your transfer case, and High range is 1.00:1 and Low range is available in either 2.28:1 or 4.70:1 ratios 👍🏼 Depending on gear choice, our Dual Case setup turns your complete t/case into a 4-speed with selectable ratios 1.00:1, 2.28:1, 4.70:1, and 10.72:1 Low ranges.
