1998 tucker 2000 t case

I'm under the impression the transfer case is a Tucker design and is not "bought off the shelf". They are a very simple design that seems to work well. The aluminum housing is in two halves and bolts together with quite a number of bolts. I don't know if the ratios are the same, but if my memory is correct my 1980 Tucker's transfer case has a gear ratio of 1.65:1.
I think there are eight bolts that secure it to the frame. One Tucker I've owned had the mounting bolts installed with safety wire. The other two used metal tabs that are bent over a flat side of the hex bolts to prevent loosening.

redsquirl can tell you all about that model he had one last year he used it for grooming but found he liked the Thiokol 2100 better. he would be the man to give you pros and con's so you can make an informed decision on it. I don't think the t- case would be a weak spot as long as you kept it full of the right oil. tucker in Oregon seems to be quite helpful when folks have questions .

I had a 1998 tucker 200 HD for several years. No problems and the blade was bulletproof. It had all the power I ever needed (pulled out several large trucks that went off the road ,couldn't believe the machine could actually do it!)
Thanks guys. this machine im lookin at has 5700 hours so if some of the components were weak it would be ready to pop as soon as i buy it. i know that the 5.9 cummins are great engines. not sure about the allison 545 though.
i noticed that they went to a different model tranny and heavier t case in later years, also went with dana 80 axles instead of 70. but what i like about the tucker is that all components can be repaired ,rebuilt, replaced by myself.parts are easy to come by. hydrostatic machines on the other hand are very expensive to maintain.

The Allison AT-545 (four speed, non-overdrive) has been around a long time and used in a ton of different applications. I think it's fair to say it has an excellent reputation. It is not electronically controlled.
I would encourage you to call Tucker and talk to them. He is now in sales but Jeff Godard was head of parts and service for a while. He's a great guy with tremendous knowledge. Dan Dressler is also in sales and is a wealth of information. They can tell you what to look for and can give you great advice.

thanks, i also noticed that they are used in the international school bus that were made in the mid 90`s ,dont know how different they actually but maybe it would be easy to find a descent used one.
The one I'm looking at unfortunately dont have diff locks. how important are those, i live in a very hilly area.

Allsion:
Not sure where you are but in WI there seems to be a allison behind every stake bed truck and school bus. some of the newer ones are five speeds.
Lockers:
I used a model 2000 tucker to pull a 10' drag in medium to high density snow. I had steel cleats on rubber belts and the grip factor on Ice was where I wish i had lockers.
lockers are a convience item 'like pockets' just make life easier.
Any time I got crossed up I generally could do something with the blade to correct the traction situation.... side hilliing, hills and creek crossing required some line selection to avoid spinning out.
I was never pulled out of a stuck situation. I did have to drop/remove the drag a few times to save the dreaded phone call for help......
Have fun.

i would be cautious as the 540 series transmissions are about maxed out by a stock cummins and really aren't much more than a turbo 400 on the inside .

the 540's are a series starting at 540 and going to 545 they are all basically the same the 545 was a 4 speed. if you had a 1545 the 1 denotes it's a 540 with a lock up torque converter. they are just about torque limited to 425 ft lbs and certainly not the ideal trans for a hopped up sled puller. my Allison guy tells me that the weak points are the clutch lugs in the case are prone to breaking out under abuse, funny part is with a pump and converter up grade a 727 will likely out last the Allison for abusive environments, also I think you will see the tuckers 6 b cummins isn't rated for more than 160 hp.
Re: Locking diffs.
Open diffs for side hilling where the hill is too steep to go straight up in deep snow works well for keeping the track side down. The up hill tracks with the least amount of weight will spin and level out the Sno-Cat. This assumes that there is no blade on the machine. I would think that lockers in the same situation could easily cause the cat to be in a "tracks up" situation if one was to spin them at all on a side hill in deep snow.

good point I had that happen once in a bv206. had to change my skivvies afterward I found me in that situation when crusted snow gave out under the machine.
