question 425 brothers

[jol1269]

it looks to me as if the back wheels on my 425 are not staright up and down when looking at them from the front or rear does any one else notice this , i put a framers square on the floor next to the tires and the bottom of the tire hits the framing square but the top is about 1/2'' tilted in towards the frame , this is on both side s ........... i havent done anything rough with the tractor and only have 20 hrs on it

Oh boy. now this will start something. Even people with wheels that look stright will be checking. I will post some pics of my 422 bought new in january 2003.

Did you measure at the wheels or the tires??

You said tires! The lower part of the tire will bulge out due to being loaded. Measure at the wheel rim edge, top and bottom.

I've never noticed. I will agree with FOURTEEN that the tires will be a bit bulged at the bottom, so that would tilt the square. I suppose you could jack up the rear of the unit, pull the tires, and check the alignment of the hub to the frame, if you want to be sure.

I have turf tires and they are still in almost new condition after 160 hours. Still have many of the little rubber Sticky Up Thingees (not ****, which was my original choice of words, but that's what I always heard them called) from the factory on them. There are no signs of uneven wear on the inside or outside edges of any of the tires.

I would agree - check against the rim - but that certainly does not look right - maybe the rim is bent - put it up on blocks (all four tires) and see if the rims spin true - It looks like maybe the rim is bent or not true - the mount looks true - so if it is not the rim - maybe the wheel motor somehow is not mounted perfectly perpendicular. The problem (if there is one) should be easy to figure out.

My first new car was a 1962 Corvair with swing rear axles that continuously changed camber. Vehicles with A-arm style front suspensions continuously change camber. Tire wear has not been a concern.

In light of the soft surfaces, low speeds, and short distances under which the PT operates, a small, or even large, amount of camber should pose no significant detrimental effect, unless it is so severe that the tread no longer touches the ground!!

The technical term for those is: Little Sticky Up Thingees /forums/images/graemlins/smirk.gif

Thanks for the clarification, you guys! /forums/images/graemlins/laugh.gif

i noticed the same thing on my 422,it looks like the the leftside wheel ie higher than the right.from the back the body is lower on the left. even the gas in tank leans to the left.i would say the welding jigs they need a little work.
if i wanted to check it,use the hub face and two stright edges clamped to the hubs,measure top and bottom,then measure from the top of the frame to the hub and see if one is higher.

OK...even though it's raining (AGAIN!)..I ventured out to the tractor garage(actually the only garage I have...cars sit in the driveway ...gotta have your priorities!! /forums/images/graemlins/crazy.gif)...my 422 looks level by sight, by gas line in the tank and by a level on the oil tank(not exactly level but close). So, this is interesting................and even though it probably won't make a difference, I have started to rotate the tires at every 50 hours.

OK, you have officially hit the PT nut level. /forums/images/graemlins/grin.gif /forums/images/graemlins/laugh.gif /forums/images/graemlins/smile.gif

LOL will that 50 hr. rotation become a recommendation. I just wrote power-trac to make them aware of this tred. I guess if my wheels were leaning enough to be seen at a look I would most defiantly have to cut the wheel mount off and weld it back on right. Every one who has this problem in just knowing this could be done if it bothers one enough will make this thing easer to bear.

If you were travling at high speeds this would be a problem, but at 8 or 10 mph and a tire with a round edge, no problem. If you want to straighten this, shim behind the motor mounting bracket by adding washers between the bracket and frame. As soon as you get the rear off the ground with a heavy load and drop it quickly to the ground, it will be out again. Our 1430 has been bounced so many times the rear tires are tilted 5+ degrees, maybe 10. We do not rotate tires, except around the wheel motor as it rolls along, and no extreme tire wear.
A frind called me to say his PT was not straight, when all he needed was to steer.
If you were using steel wheels on a concrete floor you might have a point, but rubber tires on dirt, come on!!!

well guys i didnt want to give the impression that i was concerned about tire wear because im not. the reason i asked is i was wondering if there was a reason they would have cambered the back wheels as all tires have the same pressure and i checked all tires the same way i just happen to be admiring my greenmachine when i thought man is that wheel tilted some and then i looked a lil deeper i also have the bar tread and its not had enough time to wear as of yet hence the 20 hr mark , but i was curious as to anyone else who has the same type of camber in any case thanks for the input lol and i was aware of the slight bulge in the bottom of the tire wall im slow but not that slow /forums/images/graemlins/wink.gif

I’m sure what you all are saying about speed, being in the dirt and all is correct but I would expect if I were buying a new PT now and it had tilted wheels on it I would say just let me have that other one over there it’s wheels look straighter.
