1975 Tucker 1544 - project and trips

I don't have any more new Tucker pictures, but we are allowed into the park to brush out and fix up their

trail once a year for access in the winter time for snowmobiling. So I'd like to share a few of that trip.
 
Got some snow so decided to clear the driveway. First start in 6 months.

Has anyone seen this? I would like to see the mods and build pictures for this unit!
It is a Bombardier R-18 with a modified 350ci engine. Hope the link work, I'm not that familiar with Facebook and was forwarded this item.

Okay that didn't work ....
It might be in Quebec ...
 
While waiting for the right time for another Tucker run, it was time to check the other track machine.
Good thing I checked. Found bad bearings. Ordered 100 new bearings.
That leaves 8 spare bearings.

Makes me wonder how the new rubber style Tucker track idlers are built? I thought these ones would be pretty good. But better to check than assume anything.
 
Took my Tucker out to the mountains on Wednesday and back to the truck on Sunday. I take the Tucker in 22 kms and leave it there and go the rest of the way by snowmobile as the trail past that point is not frozen in good enough yet.
After sitting for 5 days at -10c the Tucker started okay and headed back to the truck and trailer. I had to boost my truck with the Tucker though.

I noticed the air/fuel was hunting a bit in the Tucker so I think it was the snow dust melting and getting the air filter wet. I don’t think a paper filter like I have is the best idea.

I’m open to suggestions on what other people have for air filter ideas.

I have a good 360 from a 1977 Dodge van. If I get time this summer it would work great in the Tucker. We’ll see.
 
Thanks to President Trump we have lower fuel prices, the Digital Sales Tax is gone and our Woketards are not making so much noise anymore. Even the “glorious” EV mandate is on the way out. Generally things are getting better, although there isn’t much national pride.
Canada is governed by a little piece of land just across the USA border at Michigan, and Trump has their attention now.
People talk about Canada not being the 51st State, but Canada already is being shown by Trump that Canada is the 51st State of the USA. The dismantling of Canada by our eastern elites accelerated over the last 15 years and now Canada has virtually no unique identity, other than the 51st State.
Trump has done great things for the ordinary citizens of Canada by pushing our elite off their tax, control and spend agendas.
Showing our nasty elite the way it is, has been a breath of fresh air from the slide into full Communism that was inevitable.
All thanks to one man’s vision and determination. Canadians are lucky the USA has a great president for us little people.
Thank you President Trump and happy holiday.

My son sent me this T shirt he bought for me in New York. I like it.

It looks like switching out my 318 for the 360 Dodge is pretty straightforward. While I was thinking about this, I was thinking do I really need to use the Vickers pump that Tucker used? Why not use the Dodge power steering pump?

“..A 1977 Dodge power steering pump's output isn't measured by the amount of fluid it "puts out," but by its pressure capacity, which is typically around 1200 psi for a factory pump. The pump circulates fluid through the system, delivering the necessary hydraulic force for steering, but it doesn't "lose" or "produce" a specific volume of fluid during operation…”

I can increase the oil volume by welding shut the filler cap and plumbing the return line on the pump to the Tucker reservoir. The pressure side of the pump output goes to the usual steering plumbing.

The inside of the Dodge is a vane pump same as the Vickers.

Any thoughts on this?

One of the reasons for going with the Dodge pump is the increase in RPM allowed for the engine.

My understanding of powersteering pumps is they create very low volume. The psi is not the problem the volumetric flow per revolution is the limiting factor on repurposing them. I put one on a sweeper, 5' skid steer attachment 33 years ago when i was a broke newly wed. It worked but was painfully slow. When i manipulated mechanical ratios to use its power at an appropriate speed. It then got hot. I realized after some reading in a few textbooks that volume per turn is unrelated to pressure which is somewhat relevant to gallons per minute.

To me. Its like bailing a boat. You can do it with a thimble or a barrel. If its a bucket sized leak, the former will both be wrong. Use a bucket.

I think you are correct, unfortunately .....
I have a wood splitter that uses an older Kenworth power steering pump to power the ram. It works reasonably well, but not too fast (which is good! for not getting a thumb cut off). The pump is driven by a 10 hp Honda that runs at a fixed RPM on 1:1 pulley. Not a lot of RPM, which is not what I was thinking. I wanted a pump with good RPM bypass and low RPM performance, like the regular automobile power steering pump.
 
Rambling of a madman.
If i remember correctly. The pump tucker spec'd has a 10 gal per minute total out put with a built in 5 gpm priority valve for steering. This pump gives folks fits when they think its a grand idea to remove the aux hydraulics. The flow for cooling is on the aux side which often winds up returned to the resivour with a way to short hose.

The intended operation is to always have steering regardless of aux demands. Im also pretty sure they are vane pumps so rpm shouldnt drag you down down much.

What are you trying to accomplish?

The reason I ran down this rabbit hole was because I occasionally wanted to run the Dodge engine up to 4,000 rpm, but the Tucker book says not more than 3,500 rpm due to limitations of the hydraulic pump rpm.
So I wondered if the regular steering pump that Doge uses would work as that vane pump can be run up to whatever rpm you can get out of the Dodge engine.
I also don't use the aux side of the Vickers pump, so half the capacity of the Vickers pump is unused anyway.

My idea was to correct the filler tube of the Dodge steering pump to the Tucker hydraulic tank, and the pump output to the orbital steering connection.
The picture I had of the inside and vanes of the Dodge pump kind of suggest it "might" provide half the output of the Vickers.......
 
Understood.

My opinion. Take the priority valve out and spin it. Its winter. If the the pump cavitates on todays fluids and you lose 10% of its life. Thats 5-6 years.

this is a joke. The neighbor kid is going to buy the cat cheap at the estate sale. You want him to have pump capable of sustained redline....
