Selene Power Major tire sizing
Does anyone have the tire size recommendations for the Selene FWD, or know if the gear ratios are the same as the Roadless. My Selene has 7.50-24 on the front and 14-30 on the back. Before I get new tires I want to be sure of the correct size, and I also want to go to a wider front tire.
The Roadless manual (I have no manual for the Selene) list the front as a 9-24 with the 14-30 on the back, I’m not sure if someone set the wrong tires on my Selene or if they used a smaller tire on the front.

hi, cant help with selene but the roadless uses 12.4x36 or 16.9/14x30 on the rear and 9.5x24 on the front at least thats what both mine have got. I think a 38"inch rim could be used but it needed a bigger front tyre to suit.
Is yours running OK in 4WD with the current tyres fitted? If it doesnt hop and skipalong and can be disengaged easily by reversing a little way it would indicate you aren't getting too much wind up through the gearbox.

Hi Pat,
When I saw the photos of your Selene I always thought the front tires looked too narrow for the rims. My Plougmaster manual lists 9.5/9x24 and 16.9/14x30 as being a valid combination for use with a type B transfer box. Roadless figures naturally but I would expect Selene to use similar tires given the connection between the two companies.
I would measure the front rim width, my guess is that if they are 9 inch rims which would mean 9.5R24 is most likely what should be fitted. If you knew the ratio of your transfer box and diff I could cross reference it against the roadless transfer box ratios and confirm it for you. That would only be possible if you counted the teeth on the input and output gears while you had it apart though.
Regards, Frank.

Thanks for the help guys!
From what I have read it is desirable to have the front tires pulling slightly more than the rear, supposedly makes it easier to steer. With this said I could easily shift in and out of 4X4 while moving, making me think I should be running 9-24 with the 14-30, but thinking of running a 10 something-24 with a14.9-30 or a 16.4-30 on the rear.
I have 18.4-30 on it in the pic for a show a few weeks ago, and I was pulling a drag with it a few days later but I could feel it binding up.
Frans, how does your combo work? Do you seem to have the fronts pulling slightly more than the rears?
Next Question.
What did Selene use for the power steering mount on the frame? The Ford bracket will hit the driveshaft, I’m assuming Selene made their own bracket moving the cylinder up a little?

Before resauration it worked verry well it 2 years ago and I hope in 2 weeks I can drive it again Its all original pre 1960 roadless
the power steering looks like this
Iff wantet I can make some pics more but I am just working on the power sterring and the electrik

Hi Pat,
The important thing with 4Wd is to keep the roling diameter ratio from front to rear the same. If you plan to go to bigger rear tires look up the roling of the new VS the old and that will tell you what tire roling diameter you will need for the front when you multiply the ratio of new VS old. Too much maths at this point for me, but I hope you get what I mean. You can not assume going up one size front and rear will work, you may need to go up two sizes on the rear for one on the front. There are sites that list roling diameter VS tire size on the web, the rest is just maths. I am in the process of fitting a roadless conversion onto one of my tractors and the tire size ratio thing has just about done my head in. Anybody got any 28x14 rims in Australia so that I can run 16.9x28 rear and 9.5x24 front on my E27N roadless?

I set everything in place this morning. the new cylinder mount I made to clear the drive shaft is actualy to high as the draglink almost rubs on the cylinder, Ill make another droping the mounting holes down slightly.
Frans, this setup is mostly identical to the 2WD tractors other than the 2WD used the cylinder mount shown in my previous pic. This setup is probably the most common over here in the US although ther are several other systems made for the Majors as well, Sherman made their own system and I belive the back end of the cylinder was attached to the loader frame.

Where did you find the Roadless conversion? Got any more!!!!!!!!!Aussie Frank wrote:

When working mine out, I worked back from a known size(16.9x28 tyre) and diff ratios to get front tyre size.
My tractor has 13x28 rims which I borrowed from a Fiat. You could cut the lugs off and weld new Fordson ones on, or just cut the centre out the centre dish and fit new ones drilled to suit Fordson.
I do have some new 14x28 rims, but they are to suit my "Australian style" heavy cast iron centre wheels.
Would love to see photos sometime Frank.

Hi Kev,
I found it in Northern Ireland and it has cost more than all my other tractors put together. Half the cost was getting it through customs, but I expected that. Also not all the right parts and I will need to cast a new transfer case housing, but then again I always enjoy a challenge. With any luck I will actually see it tomorrow as I got a call from my customs agent today that I missed because I was in a meeting. I wish I could convince people at work that tractors are more important than new products and new income.
As for it being a real Roadless conversion, it won't realy be because I just can't find all the parts and I will have to make some of my own. So I supose Marion will become a bit of a Frankestein I will post some photos when I have something worthy of a picture.
Regards, Frank.

Re: Selene Power Major tire sizing
I finally got around to changing the front tires on the Selene today, I had picked these up the winter before last from a guy that took them off a Belarus that was a prototype for a county ditch mowing tractor, they used these small tires on the back to keep the center of gravity low.
We cut the centers out of these rims and a set of truck rims that had the correct bolt pattern, stuck them in place with my welding magnets to hold the new pieces centered and to keep them flush on the edge. After tack welding I bolted them on to make sure they weren’t wobbling around like a lobe on a bent camshaft, they looked good enough to run on a vehicle down the road, then took them off to welding them up solid. Just need to scrounge up something for the back that mach, but I’m thinking I’ll end up having to buy new ones.
