How to remove rear wheel on a 1981 650xj yahama

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others
to answer, or rely on mechanics and all. Plus I know a website that has very good manuals online, without expiry i.e. for lifetime.

This engine holds one quart of standard Yamaha YZ 250 engine oil. The oil filter is located on the rear of the crankcase behind the suspension spring. The oil filter looks like a small metal can that is screwed into the top rear of the crankcase. On the bottom of the crankcase is the plug that will need to be removed to drain the oil from the crankcase. Anyone who owns this model dirt bike can complete this job in about 10 minutes.

---------------------------------
In addition to the obvious of elevating the back of the motorcycle to get the weight off the rear tire, you need to unbolt the final drive from the swing arm and remove the final drive and rear wheel as an assembly. The drive shaft will come out with the final drive, not a problem.

Once you get the assembly off the bike, you can remove the axle then separate the final drive from the rear wheel and do what you needed to do.

When you go to re-install the drive shaft, you have to align the splines. Sometimes it is easier to put the bike in gear so the female splines on the intermediate shaft don't turn as you rotate the rear wheel to insert the drive shaft.
When you go to put it back together, just tighten the bolts that hold the final drive to the swing arm evenly in a crossing pattern until tight.

As an aside note, while you have it off, make sure you grease the splines on the end of the drive shaft and the splines for the rear wheel before putting it back together

Four spark plugs, one per cylinder; the rears may be removed with a 3/8" socket wrench, a 4" extension and a 12mm spark plug socket; the fronts require removal of the motor mounts, do one side at a time with the same tools you used in the rear. The motor mounts require an 8mm allen wrench.

don't have topaz. maybe escort will help guide you.

Section 04-02: Suspension and Wheel Hubs, Rear 1996 Escort, Tracer Workshop Manual
REMOVAL AND INSTALLATION Wheel Bearing and Hub Assembly NOTE: Wheel bearings are not serviceable and should therefore be replaced as an assembly with the wheel hub (1104).

Removal

1. Raise and support the vehicle.
   

1. Remove the wheel and tire assembly.
   

1. Remove the hub grease cap (1131) from the wheel hub.
   

1. If equipped with disc brakes, remove the rear disc brake caliper (2552) and rear disc brake rotor (2C026). Refer to Section 06-04 for the removal procedure.
   

1. If equipped with drum brakes, remove the two brake drum screws and the brake drum (1126).

2. Remove the wheel hub from the rear wheel spindle.

My reccomendation honestly as a professional Motorcycle Technician would be to take the bike to a qualified shop to be respoked for your own safety. If you really want to attempt to do the job yourself then you should go and purchase a factory service manual and practice on a couple old wheels first. Good luck and have fun.

If you tv has a hdmi input, connect it to the Yahama receiver hdmi output (out). If you are using a satellite receiver, digital converter, or a cable box with hdmi output(s), connect them to the Yahama hdmi input (in) for video and audio signals. If the above box(es) do not have hdmi capabilities, then connect the box(es) to the Yahama with either component (preferred), svideo, or yellow RCA compsite video jack (least preferred) for the video signal. For audio, connect the box(es) with optical or coax (preferred) or left-right-center-front-rear patch cords.

It really all depends on what outputs are available on the boxes and/or signal source(s).

Hope this helps,

The final drive assembly has to be unbolted from the swingarm and it is removed with the rear wheel. Once the assembly is off the bike, the axle can be removed and the final drive separated from the wheel.

It's located under the left rear cylinder side cover. Loosen the three bolts holding the side cover to the cylinder; you'll find a "trapdoor" into the crankcase. Open the "trapdoor:, and the cylinder bleeder will be immediately beneath it.
