Power stearing

[Safety Man]

I have a Yanmar YM276D that is equipped with manual stearing. Is it posible to change this over to power?

There are many 'universal' retrofit power steering kits onthe internet.. the most common are the ones with the cyl and valve as a single assembly, and your old draglink rod is used to actuate the valve in the cyl assembly..etc.

I've done this. Not very hard at all, but expensive.

My YM2220D/FEL is fairly hard steering with a full bucket which leads me to look kindly on the idea of retrofitting power steering. Your mention of universal kits peaked my interest, but so far my Googling hasn't turned up anything.

Could you (or anyone reading this) point me in the proper direction(s)? Thanks.

Before you do anything you need to check the king pin bearings. That was why mine steered hard with the bucket full. Put the power steering on and worked great until they finally froze up and broke the mount for the steering cylinder. I got my Yanmar kit from Tullohoma Tractors made specifically for Yanmar tractors.

Thanks, Eugene. I'll check out Tullahoma Tractors to get an idea of whether I think it's worth the cost.

I don't believe there's any mechanical problem, the only time I have any difficulty is stopped or very slow speeds in close quarters. I'm looking at it more as a case of operator laziness than any actual problem.

When my loader bucket is full, I have found for some reason that I can steer easier in reverse. Has anyone else experienced this? The directional thread on my tires is going in the right direction.

If I had to venture a guess, I'd say it had to do with the steering geometry. I've drawn a total blank on the technical term, but usually the axis of rotation is tilted so that, extended, it intersects the ground ahead of the contact point of the tire. That way, rolling forward, the wheel tends to trail (Ah, yes - CASTER Angle) so that the steering is stable.

In reverse, because of the caster angle, the steering is normally unstable. The front wheels, once turned slightly away from dead ahead, tend to turn to a tighter and tighter turn radius. This would reduce the force on the steering wheel needed to make the turn when moving in reverse.

Does anyone know if Yanmar equiped the 276Ds with power stearing? and if so would it be posible to retro fit mine with a stearing unit from one of them?

A character here named Nomad had something to do with a factory that made aftermarket PS units. Search here for him.. from what he said.. his company makes and sells just about all retrofit ps units to every tractor in the known universe.. plus to many tractor owners in unknown parts of the universe.

Ok.. so that is a little exagerated.. but once you contact him.. you will know what I mean.

He posted some links or pics in some thread.. not sure of the forum.

I will say one thing though, one of the example pics did have a nice sturdy looking ford 5000 in it that I was quite fond of...

Probably the easiest thing to do is lookup his public profile, and then view his messages.. starting oldest and going back till you hit a PS subject..
