Hi, I have just bought a scooter trike 200cc, WJ200ST-6 looks the same as trikers, problem is both rear wheels woble, could anybody tell me if the hub nut should be tight, or should you tighten then slacken slightly before putting split pin in, thank you for any help, bob. p.s been told to tighten as much as possible, somebody else says i'll just crush the bearing, the bike has only done 300 miles and has tapered bearings, thanks again.

Well with out a manual telling you exactly how much to tighten I would go with this. Hand tighten until snug. Tighten more with a wrench and I would say generally not more than one full turn. Make sure the wheel is not binding before you pin it. I gotta tell you though if you pull the 2 wheels and don't really notice something kind of obvious I would have to be suspicious of bent axle, bent rim or out of round tires. And you might as well repack the wheel bearing while you have it off. Look for metal slivers...indicates a problem.

Sterling, Can you take a picture of your Axle? Does it look like this especailly at each end? Left one side up by the AXLE and grab the tire and try rocking it. If it rocks you need to take the Cotter Pin out tighten the Castle nut and when tight one of the Slots Has to line up with the hole in the Axle Shaft so the You can put the Cotter pin throuh to hold the Nut at that position. If a Slot is a little off when tighten and you cannot get the Cotter pin in DO NOT BACK THE Castle NUT to aline Instead Crank on the Wrench until you can put the Cotter pin in. If you tighten the Castle Nut and the Hole In the Shaft is To far out from the Slot of the Castle Nut then you will have to Add a Washer behind the Castle Nut. Lefty

Hi edfr, Great photo, that is exactly the same as mine, it has a sealed bearing in it with no sign of metal slivers, the wheel rocks when holding top and bottom of wheel, i was wondering if i could tighten the castle nut as much as it would go or if that would just crush the bearing, i'll do what you suggest and go for tighten as much as possible, i'll let you know how i get on, it was great looking at your photo of the part that is causing the problem, in case i need new bearings would you know the part number of them, thank again, you have been a great help, thanks leeinark, hope it's not the axle, regards, bob.

Ed good explaination! Bob also make sure that the wheel is not interfering with a firm seating on the mount and there is no disruption with sitting flat on the disc. Lee

Sterling, Great! and here is a picture of what your taken apart looks like. Also on the differential there is a grease fitting, get SYN Grease and fill it up. The Wheel Bearings are number-6205RS, It is held in with a Big "C" Clip that fits in a Grove inside about 1/16 from the Bearing. Also you see that Screw to the left on the Axle Tube, does yours have those? there would be two on each side. That is to Hold the Axle from coming out. What they did is Weld a Tube Onto the Axle itself that is about 1/8 wider than the Axle and put a Floating Washer about 1/2 inch in width that the Two Screws screw into. That is so if the Axle starts to move out it will stop when the Welded Tube hits the Washer. This picture is the early version of the Axle it does not have the Welded piece of Tube that was later welded onto the axle about 6" fron each end and the Floating Washer to stop the Entire axle from coming out To take it apart you have to take the "C" clips out and if you have the Stopper Floating Washer inside you have to take the two Screws out off the Axle Tube. You have two Seperate Axles one for each side going into your Differential. The Axles have Slots on the ends and the Worm Gears inside the Differential have a Woodruff Key welded inside the sleeve of the Worm gears to grab the Axle to turn them. Lefty

The grease fitting is just a small GOLD nipple with a small hole in the center. It only protrudes about 1/4. It screws into the Differential between the Disc Brake and the Chain Sprocket. So you may have to roll the trike so that it comes into view.
I use VISU fuel filters, as for spark plugs NGK are good I use Iridium Plugs after break in. They are more expensive but they light up real good. As soon as I installed it the idle went up had to lower the idle because it was igniting the fuel more evenly and you get a bigger explosion. Lefty

Sterling, Forgot one thing to mention, which yours may already have for a little few more MPH on your Top End and that is this: Count the Teeth on the Front Sprocket Driving the Chain. If the number of Teeth are 24 you can order a Sprocket with 29 Teeth. Your Sprocket on the Differential has 30 Teeth so going up 5 teeth on the front sprocket will give you more top end. You can also get bigger taller tires: If you have 235/30-12 you can get 255/50-12 those are 4" taller. If you have 225/40-10 you can get 205/65-10 those are 3" taller. Here is Speed Tire Calculator to give you an Idea of what you can expect from a taller tire compared to what you currently have at different mph. With a bigger tire the higher your speed the more you gain. I always put in 50mph and see what the difference is ;D www.csgnetwork.com/tireinfo4calc.htmlLefty
