Anyone ever add the " Poor Mans Power Steering " to their 7013 Simplicity or Homelite T 16-H? I have seen it done on other forums and was going to do it to ours but didn't get around to it. Looking for recommendations on bearings and washers for this add. As I get older it gets harder to steer these and adding this I know would help. I know it's radial bearings and thrust washers , don't know where to get them thanks for any help. BIL and I are going to do this this winter.   Thanks again.                                                 Roger

I don't exactly know what rig you have, but, IF, I were to start over, I'd go to Fastenal.

Those folks know what you are talking about, when you "splain it to them"

Here you go: https://www.grainger...ecatalog/N-171h

 

If you have a casting for an axle, you will need one bearing and two hardened washers for each spindle.

Never heard of power steering on GT but I'm sort of new to this. I'd be interested see how and what is used.

Torrington bearing

NTA 1220. 3/4 x. 1 1/4

TRB 1220. Washer.
TRA 1220. Washer

You will need to cut small grooves in top washer to allow grease to pass thru.

It's not really power steering. It is a thrust bearing that is installed on the spindle below the axle casting to reduce friction. It has been generally found to reduce steering effort. The axle casting is often poorly milled and the spindle may be a steel rod with a washer welded in place. Not the best combination for smooth steering.

I thought that was what you had to do with the top washers but I can see that you would have to do so in both on each side top and bottom. Thanks. I am going to look at both tractors tomorrow and see what the spindle diameter is. I have a digital gauge that should be of big help in this. If they are listed in metric I can switch it to that. Thanks. Like I said I have been wanting to do this to mine for quite some time. I drove my BIL's this weekend and it would make a man out of ya if you drove it a lot. Thanks again.                                                                                                                                    Roger

Ok,,, I was having a mental image of shortening a power steering rack and running pump off drive pulley and a little fanagling with steering shaft. Sounds like a fun project

I put those on Alice and it does help. Need to do it to a few more.

There was a good thread on this several years ago. The author had a bunch of pics too. I would think that this is only needed on the bottom of the king pins. Good Luck, Rick

Headed out in a bit to make measurements. and then onto ordering the bearings.                                                                                            Roger

I add these to every machine I plan to put to work.  If nothing else, it helps save wear on the spindles.  I feel it does help quite a bit with reduced steering effort, if you have a machine that already has some wear.  If you add them to a low hour machine, the effect isn't quite a great, but still preserves the machine to some degree.  

 

The exact numbers given above are correct.  I haven't found any benefit to cutting the grooves.  Without grooves, they still get fully lubed, and if you don't properly deburr the grooves you run the risk of causing extra wear.    

 

I bought my last batch of these 3 bearing components off amazon for dirt cheap.  I bought enough to do a dozen tractors for around $1 per machine.
