Quickie Q2 Lite Construction Manual - page 191

INSTALLING THE WHEELS/TIRES/BRAKES 

.....

 The Q2 uses 5" diameter wheels, internal expanding drum brakes, 

and 400 x 5 tires standard. The wheel pant is large enough to 

accommodate a 500 x 5 aircraft tire. 

.....

Begin by assembling the wheel halves and the brake drum using 

the bolts and nuts provided. Next, mount the tires to the wheels and 

inflate to about 20 psi. Check the pressure after the assembly has 

set for several days and verify that there are no leaks. 

.....

The left and right wheel pant assemblies are mirror images of 

one another. The instructions and sketches that follow cover only the 

left wheel pant, but you will probably wish to save time and do both 

the left and right together. 

.....

To provide clearance for the drum brake assembly, which is 

located on the inboard side of the wheel pant, the tire is offset 

slightly toward the out board edge of the wheel pant. . 

.....

The LG3 and LG7 spacers are made from 7/8" 0.0. x 0.120" wall 

606IT6 Aluminum tubing. The sizing will be described shortly. Find 

QBSM1 axle bolt (2) and the QBSM2 spacer (2). The LG8 spacer is made 

from 5/8" 0.0. x 0.065" wall 606IT6 Aluminum tubing, so find that 

material. 

.....

Open up the 1/4" diameter axle pilot holes in the wheel pant to 

5/8" diameter, using a 5/8" spotface to avoid tearing the hole. 

.....

The LG8 spacer length is the width between the outside faces of 

the whee1pant measured at the axle hole; measure carefully. Assemble 

the QBSM2 spacer between the brake drum and the brake shoe. Note that 

both the spacer and brake shoe fit down into the drum with the brake 

arm pointing forward. Now, the LG7 and LG3 spacers can be made. 

Measure the width of the wheel pant between the inside faces at the 

axle h_e. Size the spacers so that there is about 0.02011 freeplay 

from side to side after they are installed as shown. There should be 

a minimum of 1/4" clearance between the tire and the inside wheel 

pant face. 

.....

LG6 is a tool made from 5/811 0.0. x 0.065" wall 6061T6 Aluminum 

tubing. It has slightly rounded ends, and its length should be 

approximately 1/8" less than the width between the inside faces of 

the wheel pant measured at the axle hole. By inserting LG6 through 

the pieces (except LG8) to keep them in the proper position (sort of 

like a shisk a bob), you can slide the assembly up into the proper 

position inside the wheel pant. Next, slide and push LG8 from left to 

right slowly, pushing LG6 out the other side of the wheel pant. When 

LG8 is resting between the inboard faces of the wheel pant, center 

the AN970-3 washers on the holes and insert the QBSM1 axle bolt. The 

axle bolt must be tightened until it clamps up the LG7 and LG3 

spacers against the bearings of the wheel. If LG8 is too long, it 

will prevent this clamping up effect; if the LG7 and/or LG3 spacers 

are too short, they won't clamp up either. Therefore, you will have 

to do
