Tucker, no power, good news, bad news.

The good news is I don't have to worry anymore why the Tucker has no power. The turbo is 100% locked up. It starts good, idles and rev's up perfect, 0 blowby. I never dreamed a motor could sound that good with the turbo no turning at all. (If a turbo go's out on one of our semi"s they smoke and will not even pull them self's to the shop) Of course the bad news is a remain turbo is over $1400.00 from Cummins!! I see some Holset turbos on E-bay off dodge pickups for less. Does anyone know what the difference would be? Its a 5.9 12 valve 194 Hp.

You will need the engine designation off the block. 6bt,4bt,6bta etc. to get the proper one. Even in the Dodge trucks they used several different ones over the years. Should be able to get a reman under $1000.

Still bad news. no one in the country had a rebuilt turbo ( it seems to be a rare build ) so had to order one direct from the Cummins factory. $1070.00 It ether had to be shipped next day air or come in on the stock order. Close to a $150.00 for next day air, So I'm patiently waiting, Its been over a week and still not here.

That sucks! Do you have good oil flow to the turbo? I would check it out before putting the new one on.

Good point, muley. Best to diagnose why the first turbo seized before doing the same to the new one...

they should be the same you may need to clock it differently but otherwise every thing should be the same the big diferences is the exhaust manifolds weather the turbo is high mount or low mount centered or slighty to the rear the standrad hx 40 should work just fine on your tucker if you have a wwaste gated turbo if you have a non wastegated turbo than you will need an early model turbo like 89 to 91 dodge trucks used

I think why this turbo is so rare is the 192Hp thing. The standard turbo'd Tucker has 172Hp but since mine came with the optional tiller the big hydraulic pump required more Hp. As soon as I get a chance I'm canning it, It's half the size of a small block Chev and with all the lines and fittings just extra weight that I don't need on the snow!!! There is a small Vickers pump on the side of the motor that runs the steering and front blade.

I had a Cummins that liked to eat Turbos once. Turned out the oil feed hose was colapsing inside the wire braid. It is not much money compared to a turbo. Maybe you should change it too??
It is also possible that you have not been letting it cool enough before shut down.

the horse power has nothing to do with the turbo the horse power is all in the pump you should have the hx 40 on that one with a waste gate when boost pressure comes up to 40 psi the waste gate opens up ad starts to bypass the exhaust side turbin a more volume will equate to more power as long as you keep adding fuel you are lucky you dudn't burn a piston as with out boost your egt's must have been high.

Good news, new turbo is on, runs like a raped ape. It will top out (2600 rpm) in 4th in about two lengths of the cat, about 18 Mph. (feels best at 12 to 14 mph, 2000 rpm in 4th.)
My wife and I just bought 25 acres on top of the Big Horn Mountains and plan on building a cabin there over the next few years. The snowcat is all part of the plan to use this cabin in the winter. It is 21 miles off the nearest all season road. Here are some pits we took this weekend off our snowmobiles. My wife is standing on the fence of our east border in about 8 ft of snow. The pic of the fence is down in the valley on the south east corner.
Here is the question for all you experienced snowcaters. Will my tucker be able to float on top this snow or will it be a boat anchor and I'll have to retrieve it in the spring. I am sure that if I pack the road in a little at a time as the snow comes It'll be alright. But for now its just fresh snow.
My cat is the 6 wheel 38" version!

When you get a deep snowfall, you may have a few issues driving your Cat, but after a few days the snow will settle down about 30 to 40% and you will be able to go anywhere you want (common sense may need some adjusting) and have the time of your life.

In Valdez, we would get thirty plus feet of snow a year, sometimes a few feet in a few hours. The snowmachine would just plow under the new snow, but after it settled, it was heaven to play "On" instead of "Under".

Sounds like you got a neat place for a cabin!:wow:

I have the exact same track set up on my Tucker. It will go places I cannot walk and it sits outside in the winter and has always been able to climb out of the hole it creates. I have a plow on mine, so I usually fill up the hole as the snow gets deeper. I have a very steep hill that the Tucker can always seem to walk up even when the best snowmobilers get stuck. I use my Tucker for the same use as you. I cannot imagine being without it. I have run it up a 70% grade in 6' of new snow and it sinks to a point and then finds the traction to do it. Just avoid spinning those steel tracks since they will dig a hole very fast. These machines are made for the deep snow and they work.
