Just bought this Murray for my Grandson for his 11th BD.....has original Tec 6 hp engine, which except for a little cold natured action it runs good when warmed up. The people who had it before traded it to the guy we bought it from, and he was just looking to get his money. $175 was a good price, I thought, for a running kart. It has had some welding done on the steering and I think it is not repaired properly. It doesn't turn right very far, and does better turning left, but still isn't turning like it should. It also has the camber on both steer spindle axles swagged out at the bottom. The bearings seem tight, and smooth, and I think the swag is in the wheel spindles outward of where they come through the spindle yoke that have the kingpin running through it. The king pins are tight and don't have any looseness where it is attached the axle, and I don't see any swag in the axle. It is welded into the frame, so it is solid.

What I think I see, is the people when they welded the pivot where the steering linkages attach, are mounted on a single stud. When the wheels are turned right, it doesn't throw the right wheel far enough right, while the trailing left wheel looks about like it should on the steering angle. When turning left the pivot throws the longer of the steering links further left, but still not quite enough as I think it should and the right trailing steer wheel isn't trailing into the turn enough either, yet is better than the right turn when the left steer wheel is in the trailing position into the turning diameter.

I think the steering column should have two locations for the two steer links to mount separately. The way I envision that action, it would throw the trailing steering better , and when that same wheel becomes the leading steer wheel it would throw it into a tighter diameter turn radius.

Any which way, the repairs they did, have it messed up in the turning part of it. I know what the steering angles should look like based on looking at my Murray riding lawnmower. I don't have an owners manual or even a parts manual. So I don't know how or what the steering links are hooked to, or how they should be hooked up at the base of the steer column.

The model number is GT60303x92D

The photo is my Backberry, so it isn't a very good shot. I''ll try to get out there when He isn't running it, and use my Sony camera, and get some better closeups of the links and steering column and angles produced in the turns.
Any help or even a phot of an original set up on a Murray Kart, a diagram closeup of what it should look like so I can get the steering fixed up before he wears out the tires.

The left photo is what I bought, we didn't get the top roll bar part....like the one I copied from here. I just wanted a photo of the correct version so you could visualize better, what I had. We are supposed to be able to get the original roll cage parts from that previous owner that did all the welding.

Better front end photo's

Here are better photo's....


With a closer look, I believe the single stud is correct based on a parts diagram I found on PartsandService.com.. ....but they broke the tang that the bolt for the tie rods Heims joints attached to. Instead of welding it back on as it had broken, they place it on the end of the steering column without lengthening it. It looks like it should be about an inch (1 inch) longer and that would probably take care of the right turn problem.

just go around the block backwards! it looks to me like you should just start all over with the steering if you have the budget for it

See how bad the steering gear is worn, you might be able to weld a washer behind the assembly to snug up the steering for a semi permanent fix for your application. Sadly Murray experimented with lawn mower linkage for a short period of time.

Well it is even more simplified than the sector and pinion gear set up like in the Murray's riding lawnmowers they built. All it has is a simple 1/2 in. shaft for the column with a welded tang or "L" at the end of the column that has the hole in it for the Heims joints to be mounted onto the bolt passing through them and the steering tang.

This is the partsandservice diagram for the model I have.....

And this one is a similar model to the one we have , but has a better look at the steering mechanism.

http://partsandservice.com/html/Murray/go/gogt60503x92a.html

If someone here on the forum might have one of these, if you had measurements of that "L" tang mount for the steering tie rods to be bolt onto, it would help. If not, with the cobbled up mess for a steering column the PO did, I'll just guesstimate it, and tack weld a new "L" onto the new column, and see what the lead and trailing angles of the wheels in full turns look like. I'm guessing a 1" additional length to the "L" that has been welded on the bottom end of the column would be fairly close. I will attempt to duplicate a rider in full turns and create a plywood jig pattern to try and duplicate the turn angles. I might just have dumb luck in that attempt. The other main thing to do is get the swag out of the spindles so the wheel/tire is straight up vertical and not out at the bottom like it is.

Thanks for any help and comments you guys might have.

Well, I've been busy in the last few days. I actually dragged the welder out, when My G'son broke the weld on the steering wheel support to the center frame tube. I welded it real fast and then decided to try and correct the steering.

I guessed on the tie rod mounting tab at the end of the steering column, that it was too short to give the tie rod enough throw to the wheel on the right. I added an inch to it and re-welded it back in that longer position. It fixed the turning angle to allow it to go to the stops in both directions. In order to fix the swag in the tires angling out at their bottoms, or camber, I discovered the spindle axles weren't the problem but the main axle was swagged under the floor pan. I did a little "big hammer" adjustment on the king pin's clevis or pivot of the spindle axles and basically bent the top and bottoms down to change the camber. That seemed to work pretty well, and they are straight up now. So after these changes were made, all I had to do was adjust the tie rod ends to adjust the toe in. Now to get the roll cage replaced, that I picked up today from the previous owner. I did get one of the seat belts, but need another. Anybody got any idea where I could get some.

Just in case anybody is interested, I'll take some shots of the changed steering and axles
tomorrow.

Edit: OOps, it rained really hard yesterday when I was supposed to take the photo's, and today, the bug population exploded after the rain.....they almost carried me away. I gave up and went inside. I'll try to get the photo's tomorrow.
