Yeah, don't let it fall on you, It hurts.

Getting it in is the biggest problem, Me and 3 buddies worked pretty hard to get it in. If it wasn't raining, wasn't in gravel, and I had a trans jack, it might have been easier

 

with an auto, which in reality is what most people prefer, it would be fine, but they tell you in the instructions that you'll probably have to bend them for the perfect fit

 

I feel your pain! My lab has decided that I needed craters...craters not holes....dug under my shed. A trans jack wouldnt roll even if I had one.

 

Not meaning to Hijack this thread and all, but I got a question about twin sticking a t-case. I know that with the twin stick, you can unlock-lock the front seperately from the rear, but is it possible to run the fron in say hi range and the rear in low range with out any bad things happening? Or is this something you'd really want to avoid?

I'm looking at this for my mud truck I'm building. A lot of the guys I know run different ratios front to rear (like 3.73 front and 4.10 or 4.56 rear) to gain a little more wheel spin up front to keep the truck up and moving in the deep slop. I was looking at this same thing, but by going to hi in the front and low in the rear (or vise versa) , I could essentially accomplish close to the same result and open me up to better tuning depending on the track. Keep in mind, this is for soft mud only. The truck will be in 2wd after it comes out of the pit and never see pavement.

 

its not possible with a regular twin stick.....bad things would happen, unless your spinning your tire the ENTIRE time your moving, or if you had different size tires front and rear, but that is WAY to much difference between front and rear ratio......

 

this is what happens...

and that was only one of three times until i finally figured out i had 3.55 gears in the front and 4.10's in the rear! i learned to NEVER trust the person who sold you the axle! always check for yourself!

Wel, now that's an answer I can see!! I guess I'l just stick with the standard single stick option and run it like it was meant to be. Just looking to get an edge and be easier than doing a gear swap depending on the conditions.

 

NICE!!!!!..........

 

It would be possible with the right mods done, I think you have to grind more on the shift rail than normal or remove an interlock pill or something, but I too think it'd be a little too much of a ratio difference to help. The fronts would be spinning almost double what the rears were, and most mud racers that use that trick the ratios are pretty close. Good Question though.

 

its just a flesh wound

 

lol well it did limp all the way back to the shop! its been good though so far. been on 4 trips since and countless impromptu romps through the woods with no effects!

It's not possible to run HI and LOW simultaneously on an NP205. LOW engages additional gears and it's necessary that a particular HI gear freewheels on its shaft while in LOW. Engaging both HI and LOW will lock-up the case.

 

it is possible if you grind too much off the shift rail when you twin stick it

 

I think were talking about two different things. It's not possible to have High and low engaged on one output at the same time. it is possible to have front high rear low or visaversa at the same time IF you grind where you shouldn't.

Is that what you meant?

 

While it's possible to shift the case into HI on one output and LOW on the other if you grind too much, the case will only lock up. The input shaft is always spinning at a 1:1 ratio, as it's connected to the transmission. HI on either shifter locks its output gear to it.

LOW gear reduction is done by engaging a set of backgears driven by the input shaft. These gears normally freewheel on the input shaft. But when in LOW, each shift fork decouples its HI gear from the input shaft and couples it through the back gears.

LOW or N on the rear output allows its HI gear to freewheel on the input shaft. LOW or N on the front output allows its HI gear to freewheel on its shaft. So in turn if either output is in LOW, the other had better be in LOW or N to allow its HI gear to freewheel, otherwise the case will lock-up.

So in other words, LOW is achieved by using part of the HI geartrain.

I hope this helps explain it.
