I'm looking for an underdrive "box" for a 230 transfer case. I have a 3.9 and a 380 trans. I just recieved an e-mail from Ashcroft and they no longer make one. Timm is still far away, does anyone else make one? Thanks | ||

You could install maxi-drive crawler gears in your transfer case. 30% lower. Talk to bill at GBR John D | ||

Thanks- John, but I need a lower crawl ratio; And I didn't want to change my ring gear. How about dual transfer cases or a Dodge 203 case between the 380 and the 230? Tim | ||

Check out East Coast Rovers in the vendors section. I believe they sell them. Zane | ||

I believe they sell the Ashcroft version. Anybody have dual transfer cases? Tim | ||

Tim, The crawler gears that John is talking about are simply a different ratio low gear in the t-case. The high range gears stay the same, as do the r&p gears. They should give you a substantially lower crawl ratio without changing the performance in high range. It's not nearly as versitile of a set up as a crawler box (which gives you low and low-low) but it should get you what you need if you can't wait for Timm's crawler box. Which BTW I hear is going to be super cool. Thanks, Nathan Hindman http://www.pangaea-expeditions.com | ||

Tell more about this Timm crawler box | ||

Acutally, the guy that's making it is Timm Cooper. He's sort of an fabricating guru up in the Pacific Northwest. Basically, any thing you can dream up he can pretty much build. IIRC, he did a lot of the work on Mike Slade's Serious One, and his D147 as well as a few other trick rigs. Anyway, last I heard, he's built a couple of prototype crawler boxes. They're similar in concept to the Ashcroft design, but the design and craftsmanship is a bit cleaner. It also is SUPPOSED to have it's own oil bath, unlike the Ashcroft which shares it with the LT-230. This should cut down on friction, wear, etc. As far as when he's going to start production on these puppies, I don't know. I was planning on asking him at the Nat'l Rally if he goes again this year.

Just talked to Timm to inform him Ashcroft isn't making their crawler box anymore. That seemed to spark an interest, but he still said "mabee winter" before he would look into it. He doesn't know if is profitable. I mentioned to him that I would be glad to put a deposit down for his trouble. He would like to know if he could sell more that one or two. Would anybody else be interested? More that saying yes, to actually call him and give a deposit. If a crawler box is going to cost $2000.00 than a deposit of$1000. would be fair, wouldn't it? Call Timm (805.237.0738)and let him know us "Land Rover fools " need a crawler box not lower gears in the transfer case 60 to 1 is not enough, for rock crawling Thanks Boxerhips | ||

I would love to buy one from Timm as well.And it will be no problem at all for me to put a deposit of $1000 or more.Please let me know if you got any further information.my email lingyangwu@yahoo.com Thanks, Lingyang | ||
| Timothy Riccardi (Boxerhips) New Member Username: Boxerhips Post Number: 35 Registered: 07-2002 |
Lingyang thanks for the response, I will. Shaun I know Maxi Drive has gears for the lt230 but that only gives 56 to 1. What I meant in my previous response, I would still have to change the ring gear to 4.70 to get a crawl ratio of about 75 to 1. I would like 100 to 1 to rock crawl. 75 to 1 would be ok if it was a trail rig. Thanks | ||

Regarding Ashcroft, I believe there is no quality control there. I have seen more than one of their Hi-Ratio transfer cases for the Series vehicles that should never have left that company. The axis for the idler gear holes are not close to concentric and the larger of the two holes is usually too large. I don't know what goes on over there, but half the time, they aren't paying attention. Too bad typical English workers aren't as anal as Germans or Japanese. | ||

Would swapping in a NV 4500 help with its 5.6 first gear? There is a guy on the d90 list who makes adapters to mate that with the LT230..sorry I lost the email for him when my HD fried..... | ||

Maxi-drive also make 40% reduction if you ask, so the web site says http://www.4wdworld.com.au/products/maxidrive/index.htm | ||

Any more "actual" info on the Timm crawler box would be nice. I'm interested, but never plop down that kind of money without some info... | ||
| Jaime (Blueboy) Senior Member Username: Blueboy Post Number: 732 Registered: 02-2002 |
while looking for info on changing out my transfer box, this is mentioned on GBR's site: "Tech Tip: As with all things you can over do anything including low range gearing. In our opinion anything beyond 80 to 1 compound low is unnecessary. Most experts consider 60 - 80 to 1 to be the ideal low range ratio for even extreme off roading." does anyone have any experience using a ratio in the range mentioned above? | ||

Depending what kind of offroading you do, that is just not enough. In the "stock class" of Neurock you need 100 to 1 or you will kill your clutch. Most offroaders will do fine with 60-80 to 1, again depending what you do. If you are the drive on a dirt trail and go camping type 60-80 to 1 is perfect, heck mabee even40 to 1. I was unaware of Maxidrives 40% redeuction. I wonder if they make a 40% reduction along with changing from 1.2 to 1.0 in high range, then you could get 4.10 ring gear. I think that would give around 70 to 1, and your final would around 2.87 instead of 2.97(not sure of exact numbers but close enough). Tim | ||

Why don't you just adapt and install an Atlas 4:1. Anything can be done with enough time and patience. If would probably be cheaper than an LT-230 modified with the Crawler gears IF you did this yourself. Larry | ||

I had a yota with the 4.7:1 duel case set-up. I had 5.29 ring and pinion that took my crawl ratio to about 150:1 or so. I then added a turbo motor and transmission. The first gear on the turbo transmission was a little lower. Im guessing my crawl ratio then was about 175:1 Even with that ratio there were times I would be coming down a steep, off-camber, rock and wanted to do slower. It's all in what you do with your truck. IMO, a discovery will most likley not be doing that kind of "rock crawling", so 100:1 with the auto transmission would be fine. | ||

Will, I think he is going to be using a manual •••••• with this. If it were an Auto I wouldn't want too low a crawl ratio, otherwise your brakes might not be able to stop the truck! Larry |
