I was checking brakes before our Branson trip, and noticed that one of my bogie brakes was loose. I pulled the tire to check it and realized that the tire was at 1/2 or less tread. The drive was about full. All were put on new with about 16k miles on them. I called a conference in Branson to discuss. Wayne asked about the other bogie, and we found full tread there also. Jim Hufford had new tires and a bogie wore in a short amount of miles. He pointed out the slight black film on the side as tire rubber. I have everything in the front new as well as the drive. The bogie is the only part of the original bus left!!LOL My wife drove for a while on the way home and commented that she felt like she was making constant corrections. I replaced the entire drive axle when I replaced the motor and did an alignment check then. I have never checked the bogies, but when I removed the old rear I noticed that one the adjustment rod on the drivers side had been broken and re welded about half A**. Bingo, the light goes off. A bent bogie will not only wear, but will constantly push. I called Gary Labombard about his pulling fixture. He came over and spent the entire day helping my get the arms off of some model 15 bogies I had. We also got the top of the blots off on my bus on one side. A great bus nut!!! I have to say that getting those off my bus was a chore. Bent the fixture, so I just cut the arms!! I have ordered all new shocks, and inner bushings from Jefferson. Any one who wants to help is welcome!!!LOL

Eric, two thoughts.

At Cody we discovered that one of my bogie tires was worn badly and much more that its mate. I had known that the bearing clearance was excessive on that wheel, but did not get around to adjusting. After we mounted a used tire, I adjusted the bearings and all seems to be fine. I ran into the same problem with front tire wear. Readjusting the bearings cured the wear. It was my fault in that I set the bearings too loose.

Second, I would "string" the bus. That is where you run very tight string down both sides of the bus and check toe-in alignment on all of the wheels. It sounds like you need to also check the rear end alignment. I played with the string process. Pretty straight forward. I put square tubing against the front and rear bumpers and supported the tubing with jack stands. I adjusted the string so the it was exactly parallel to the bus (distance is not critical - I set mine about 6 inches out from the sides). Then I measured the distance from the front and rear of the tire to the string (value is not important - you are looking for relative values). If you take a lot of care, I think you can check alignment fairly well. I played with the front tires to see if it was a good check of toe-in, but I prefer my jig where I have thread rod in tubing.

Lots of work there Eric I would have tried the wedge shim and the bearing adjustment first you cannot bend the arm but the spindle will bend a little curbs are tough lol

FWIW I never saw a bogie off far enough the wedge shim would not bring back to specs

good luck

You are right Clifford. The shims would probably have fixed it, but I wanted to get the bigger brakes. Also,the 05 had the drum and hub bolted/riveted together. A pain to work on. I had the arms off a couple model tens anyway. I am going to string the bus as Jim suggested. I am also going to use the trig. method with three points just to verify. Jefferson told me that trailways just used a long straight bar with two post welded on. They would put the flat post against the rear wheel at midpoint and verify with the string. He said they even had a written procedure and it was always closer than from the factory. He is going to fax it to me. I did notice that the two arms I am going to use both have shims ( the thin set). The arms had never been indexed so I assume they were set at the factory. I think on a 1985 model ten. Looks like they would have set a slight amount of toe-in on each bogey. I will know better when I mount the arms.

I found information on line on how to tap a jack for a gage. Jefferson gave me the number for the NAPA jack that eagle used. They quoted me a cost of $ 228.00. I got an 8 ton jack for $ 30.00, and a 5000 lb. gage for $35.00. I have one arm on and the weights seem to work correctly. I am shooting for 4000-4400 lbs. for each bogie.

Jack with gage.

I hope there is some rust bullet left when I get ready to paint the 15. You need to own stock in the company. You will be happy with the larger brake.

You are right Wayne!! I think I must have used 5 gal. of the stuff at $$$$$!! I talked to them several times before I started. They told me it is better to buy the quart size rather than gallon. Keep it in the refrigerator until you are ready to use it. Do not work put of the can unless you intend to use the entire can. The chemicals evaporate quickly when exposed. I used a plastic bowel and brush when not spraying it. When you close the can MAKE SURE NO PAINT IS IN THE RIM!!LOL I had to turn the first one up side down and use a can opener after I did that one!!

I made my own redneck alignment machine to pre check the bogie alignment. I used a wooden jig over the hub, then attached a new 6' level. This gives me a sight with the side of the bus past the first bay. By measuring at the ends of the wood jig ( it is roughly the same length as the tire dia.) I determined that the drivers bogie has a toe out condition of app. 3/8". I will shim to a toe-in of app. 1/16-1/8".
