does anybody have any info on the underdrive unit that replaces the small driveshaft between trans and t-case built by tim hardy????? I have an 88' sami with RR 6" SOA w/ rear leaves up front shackles 5.13 tracker gears and 33/12.5 TSL locked up frt/rr. Stock mtr, need lower crawl ratio looking for other options than lower t-case gears just curious!

Big discussion on zuwharrie about it and the idea a while back.

http://bbs.zuwharrie.com/content/topic,34651.0.html

Build a few then sell one to me! :D

Think forklift components...

any body know what componet that is on afork lift? what it is called?

it looks like the planatery output on a hub of a drive axle from a fork lift, or anything with planet drive, that he changed a lil to make it mount to the frame, and still have an inline in/output, instead of in on one end, and the hub driving.

thanks for the info, i am still shopping around trying to find one

the gear box might go between the tranny and drive axle on the fork lift

my uncles has a big chain that conects the tranny and drive axle giving it a 3 or 4 to 1 reduction

Have you tried searching? There was a post on here with pics and everything about a month ago.

Like this one?

Looks like you could machine each ends of the intermediate shaft to fit on this:

any one know where i can find one (or beter two) of these planetarys? i have been calling fork liftplaces for a2 weeks now and all i ever get is "you have to have a part number for us to find you a part"

sounds like Auto Zone...:laughing:

I have and use the 3.5 to 1 under from Tim Hardy. No it is not for sale.. (Well how much:D )

I do not know if Tim will ever build another one (He made 2, they were made from C-4 Planit's

Call him 530-642-0436 You will have to leave prob a couple of messages before he finds time to call back.. Just a busy guy....

I think I can find my pics I did from an extensive thread here I did a couple of years back....

ok sar how is it mounted I 'm pretty sure it in no way mounted to the frame .. and please take some pics for us

OMG:eek: They do exist. I have been hearing about them for a few years now. If you find the pictures please post them. I, among many others would love to see them. DO have a link to the thread?

Still looking..

To answer a previous question. Yes it bolts to the cross frame.........

The pics shouldn't be too hard to replicate (just look under your Samurai).

What does "C-4 planit's" mean? Is the C-4 the model number of the planetary, the model number of forklift the planetary is found on...what?

C-4 would be a Ford automatic

C-4 would be a Ford automatic

Yeah, I know a C-4 is a Ford auto tranny.....but with all the previous talk about forklift planetary hubs, I thought SAR_Sammy was referencing a forklift "C-4".

Yes you would think it would be an easy one.. But Then I have to take off the skid plate, then un-bolt the under drive and take it out (Well there goes 45 min) then take pics. Oh when done put it all back together.. Next contact Lance re-up my deal so I can post.. Or I can just take the easy way and look for the old pics and then contact Lance.... Feel free to come up to Pollock Pines and pull it out if you need the pics right away.. Weekend's coming up??

I didn't say anything about needing them right away. I was just saying, if all else fails, you can just look under your sammy.

So is that correct....the "C-4" you referenced is a Ford tranny C4 planetary gearset?

Yes you are correct. It is a C-4 Ford Automatic. Same Planetary, 2 configurations 1.25 and 3.35 or close too... Wrapped in a hand rolled Aluminum case with exact input and output shafts. Perfect fit replacement for the intermediate shaft. I'll get the pics soon

I guess not.

Check out the "Rock block" made by Trail Tough. It's pretty expensive but should be wehat you are looking for.

Nope. Spending big $$$$ is NOT what I am looking for. I am trying to find some detailed info and/or good pics so I can look into making an underdrive intermediate shaft.

just get a kicker setup from OTT.

just get a kicker setup from OTT.

Hmmm. I am running a samurai tranny right now....so how is the kicker setup going to work? All I saw was one that adapts a samurai tcase to a trackick tranny/tcase combo. And they were $600....if I was going to spend money on something that would give me some gear reduction I would just buy some $400 tcase gears.
Hell, maybe the underdrive shaft that I am looking for will end up costing just as much (or more) to make....but I would like to check into it to find out.


....still waiting on some pics of the underdrive intermediate shaft......

so you want a underdrive intermediate shaft (which would be custom made) that will cost less than t-case gears?
If such a thing could be done, don't you think more Zuke owners would have one?

maybe you should investigate homemade dual sami cases, or homemade trackick doublers.

Well I know of a forklift salvage place, so I should be able to get parts fairly cheap. And my bro can help me with fabbing up the custom shaft. So yeah, I am hoping to build one for cheaper than what I can buy tcase gears for. Plus if I need to drive the samurai on the road...take out 4 bolts...drop the shaft...bolt a stock shaft back in...and I am back to a stock ratio. Let's see someone do that with tcase gears.

Already looked into dual sami cases. Haven't found anything to compensate for the off-set tcase output. Heard if they are tilted (to try and get everything to line up) there are oiling issues and shifting issues. Plus they will either hang down really low or you need a big body lift to clear 2 twisted up samurai tcases.
Trackick doublers...so now I need to buy 2 trackick tcases instead of just one.

So for the lucky13, I need to buy the $50 adapter plate, a trackick tranny and tcase. Then I still need to adapt the trackick tcase to the samurai tcase.......I can hear the sucking sound now of money leaving my pocket.

I appreciate the alternative suggestions....but I am just looking into the intermediate shaft reduction thing for now. It has been done before...I want to see what it takes to replicate it.

I agree with you. Theres a lot of info on dual t-cases, but not much on this idea. I have been thinking on this for a while now too and know there is the answer out there. I know lots of ideas are out there, but just need the right one. Just have to figure out a planetary gear set-up like a winch that would be strong enough and shiftable would be nice. I have seen a guy a long time ago that used a dana 20 t-case cut in half and made a custom divorce style mount for it and shoe horned it in there. I only wish I knew who it was or where I saw it. Just have to think outside the box. I am not familiar with forklifts, but theres got to be some sort of farm tractor part out there that could work. Time to play on the net i guess.

NP/NV 231 planetary setup.

and you get an extra shifter to play with. I don't sell too many though:(

Dual Track/Kick cases add approx 7 inches.......but it's no Tim Hardy underdrive!

7 inches longer than a kicker3 - but it's great. I have not seen anyone make one of those yet.
Great job.

Great job.
I don't know the length of a Kicker 3, but it adds only 7 inches to the Track/kick stock Tranny/T-case setup. It's a PITA to build with a custom main shaft and custom adapter plate. This is the 1st generation i complete last year, but I am in the 3rd gen adapter kit right now and I believe it to be close to production quality. Just need to do some testing. :smokin:

Sean

So that would make our rear driveline a whole few inches long? :D Assuming a CV would be in need?

hmm, maybe it's not as long as I think...

a kicker3 in a samurai, leaves the tcase in the stock location. wonder how the 2 compare.

Like this one?
Where can i find this forklift drive shaft!

Crawl under a forklift with a ratchet and an all-size socket and you'll find that kind of driveshaft connecting the cooling fan to a pulley that turns the propeller normally found in the carburetor.

Thanks you Canadian F**k your very helpful go drink some warm beer.:flipoff2:

edit: I hate internet bashing, and there is so much going on in "general" why cant we sami owners stick together just help each other out instead of this shit.

you know what i kind of like this idea. kinda like the klune. ive been thinking about making one of these for awhile now. all it is, is planetary gears in a cylinder, just need to make it selectable. time to start my engineering program again:idea:

one out of a fork lift would be cool but way overkill and heavy. i have some around my work and the cases are made out of aluminim. ill let you guys know what i come up with.

my kicker 3 didn't add anything i bolted it in between my engin and sami t case ... and bolted it back in no change except almost 200 to 1

Yeah the kicker is definetly a good answer Im just not wanting to replace the stock tranny yet as it was just rebuilt and work great. As for it being shifted that would definetly be cool but for my trail queen not a prob.

You say that until you are going across the dam at loon doing 20mph in 5th gear and the case in high. You want selectable! I went on a trip that SARSAMI went on (he has the tim hardy non-selectable jobber) and that thing was useless low when driving to the trailhead even in high range.
Travis..

Hmm Im glad someone has seen this thing. I like your point crash its already slow enough and that might get annoying. Im still really just looking to find out that my current gearing will be low enough, guess I will find out at the round up next weekend. thanks Ryan

I think I remember reading somewhere that Tim would run a stock intermediate shaft until he got to the trailhead and then swap it out before doing the trail.

I have that.

The final ratio is 176:1, was made in chile by a friend (www.chilecustomgears.cl) with planetary reductions

:)

hmm that would work my spanish sucks so i have no idea what it all says except 2.7:1 which would be perfect but how much does it cost looks a lot like a klune

hmm that would work my spanish sucks so i have no idea what it all says except 2.7:1 which would be perfect but how much does it cost looks a lot like a klune

the price is approximately Us$ 1.000

This underdrive replaces the short drive shaft and has 1:1 in high and 2.7:1 in low.

And the coolest thing is it's part time, and Tim's device is always engraned.- Yes, with planetary reduction, like a Klune.-

bump any update

I want more info too!!!!!!!!!!!!!!!!!!!! I know it can be done what parts do we need for a non shiftable 3 to 1 underdrive shaft. i know its not practicle but big deal. Were are you tim hardy

Can you get anymore of these???

I have one of the last of Tim's Underdrives. WOW!! what a reduction

4 to 1 X-fer
5:89's in the Diffs
Underdrive

215 High Range
335 Low Range

If it doesn't climb it, It drives thru it at idle..

Since my Sammy is a Trailer Queen I don't worry about taking it out.. However if I do Bash plate and all it only takes about 20 mins to take it out or put it in..


For Sale Let the bidding Begin.....

PM Me with your offers

Oh last thing.. Completly re-built new planetary, bearings, seals, etc.. I will be getting it back in hopefully a week.

Reason for selling? I am selling my Sammy anyway so I will not need the underdrive....


Mike

pictures - lets see lots of pics of it.

Not much to see.. Looks pretty much like the pics above, but without a shifter. It bolts to the cross member to keep it from rotating..

Those wanting the exact pics will have to wait until the underdrive is re-furbished. Again reason for rebuild is my Buggy is up for sale and I wanted whom ever bought it not to come back a week later stating "Hey dude your junk broke" I knew it needed re-building so I am having it done pre-sale...

The re-builder is well known to the Rock-Crawling community but will remain silient. He does want to be bothered about making anymore. He is just doing this one for me..

Oh and I found an old link from a while back

This is the important quote, from someone who actually has one. Too many people seeing the bare reduction unit, thinking it works like a magic driveshaft, not needing something to keep it from rotating, able to be installed with zero mods to any sammy for instant no-mod gear reduction.

I'd run one :D
