c. Removing and installing the rear wheel
The rear wheel on the G Plus Mariner can be removed or installed without tools. A quick release skewer through a
hollow axle is utilized for easy and quick wheel removal. A quick release skewer is a rod that has a threaded acorn
nut on one end and a cam lever assembly on the other end. The cam lever applies pressure and locks the axle in
place. The majority of higher quality bicycles produced in the last decade incorporates this design. Prior to
removing the wheel you will need to release the V-Brake. (SEE PHOTOS ON NEXT PAGE)
When removing the wheel, it will be easier to turn the bicycle upside down and rest the bicycle in its saddle and
handlebar. Place a few blankets on the ground as not to scratch the saddle or handlebar controls. To remove the
wheel, follow these steps:
Review Chapter 7 "Maintenance and Replacement" section d "Brake pad replacement" on
understanding how to release the V-Brake in detail if you have problems with the following summary of
releasing a V-Brake. The V-Brake's pads must be moved away from the rim for the wheel to easily
slide out and away from the frame. To accomplish this, the V-Brake needs to be released and open. To
release the V-Brake, you will need to squeeze the Brake Caliper Arms together and slide out the Inner
Cable Lead (cable guide/noodle) out of the Cable Lead Hook unit.
After releasing the V-Brake, locate the quick release lever on the left side of the bicycle (opposite the
chain side) and pull the quick release lever open and away from the frame.
The quick release lever being opened will loosen the grip on the frame and the wheel will now slide
back and forth easily in the dropouts.
The chain will need to be removed off the freewheel gear. Push the wheel inwards towards the center
of the frame and pull the chain off the front crankset chainring first before removing the chain from the
hub. This will allow for slack in the chain. Once you slide the chain off the front chainring, you will now
be able to remove the chain off the hub freewheel gear.
The wheel is now ready to be removed off the bicycle. If the brake pads are fairly new, the tire may rub
against the pads when trying to remove the wheel. If the tire is too close to the pads, you can let some
air out of the tire and pull hard to remove the wheel. You may also loosen the brake pads and remove
them if preferred. See Chapter 7 "Maintenance and Replacement" section d "Brake pad replacement"
on how to remove the brake pads.
When installing the wheel, it is basically opposite of the above "removing the wheel'. Follow the below instructions
on installing the wheel:
Check to confirm the V-Brake has been released. The above section explains how to release a V-
Brake. For a further detailed explanation, see Chapter 7 "Maintenance and Replacement" section d
"Brake pad replacement" on understanding how to release the V-Brake.
Now check to make sure the chain is not on the front crankset chainring. If the chain is on the
chainring, simply remove the chain and let it rest on the crankset spindle.
Bring the wheel close to the chain and place the chain over the wheel axle and around the hub
freewheel gear.
Slide the wheel axle into the frame dropouts. You may need to push firmly the tire pass the brake pads.
If the tire does not fit through, remove air from the tire. You may remove the brake pads if you prefer.
See Chapter 7 "Maintenance and Replacement" section d "Brake pad replacement" on how to remove
the brake pads.
Once the wheel is in the dropouts and the tire is pass the brake shoes, slide the wheel in towards the
center of the bicycle frame to allow slack in the chain. The chain can now be placed over the front
crankset chainring.
Install axle quick release skewer if it is not installed. With quick release lever fully open, tighten acorn
nut until a slight resistance.
