Assembling the new Mirage Drive drums and cables

Caution: The new cables and drums are slotted for easier maintenance and

tune ups. They are not interchangeable with the older parts.

Warning: If cables are installed incorrectly, they may twist off the drums,

causing the Drive to fail.

Tip: DO NOT REUSE Nyloc nuts when installing new cables. The slotted cable

threads have 40% less area -- worn Nylocs may back out causing Drive failure or

adjustment problems.

Tools and materials required:

7/16 inch wrench

needle nose pliers

Marine grade axle grease

Preparation:

1. Remove old drums, cables and chains

2. Wipe drum axle clean

3. Pre-install crank arms to the drums, noting left and right crank arms

Installation:

1. Install new chains / cables on

sprockets, taking care to press chain

solidly into master cog (Plastic sprockets

only). This may be accomplished with the

masts and fins on or off. Verify that chain

is properly centered. (Tip: mark center

link of chain with marking pen for easy placement).

2. Lightly grease drum axle

Note: there are two methods of assembling the cables to the new drums -- on the

bench (3 through 7 "A" below) or with the drive properly mounted in a bench vise

(3 through 7 "B" below). Each is described separately. Use which ever is

easiest for you.

Bench method:

3 A. Mount left or right drum / crank arm assembly (noting correct side) onto

drum shaft

4 A. Install front and rear cable into upper drum slots as shown. It is easiest to

angle cable in from the side (below and right).

5A. Slip cables over top lip and hand

tighten new Nyloc nuts to keep cable

from slipping out (right).

6A. Insert idler cable into rear slot as

shown. Note -- this slot is divided -- use

outboard portion of slot (left).

7A. Flip drive over and repeat on other side.

3

Vise method:

3 B. Secure Drive to vise by rear

portion as shown. Use a rag in

vise to prevent marks (rag

removed for illustration purposes,

right).

4 B. Mount both drum / crank arm

assemblies to drum shaft, noting

correct left and right side.

5 B. Mount the rear sprocket cable. Note, the cable is first inserted from the

side, with the help of needle nose pliers if necessary, then re-routed over the top

lip of the drum. Hand thread Nyloc nuts enough to keep the cable from slipping

out (below).

6

B. Repeat procedure with the front sprocket cable.

7 B. Insert idler cable into lower rear

drum hole as shown. Note, the idler

slot is divided -- use the outboard

portion only (right).

8. (both methods) Tighten and tune all cables. Make sure they are running

properly on the drums (below). Align and center fins as necessary.

Troubleshooting:

1. Cable wanders off drum. Cable is twisted. Remount, removing twist or

warping cable toward inboard side of drum.

2. Cable appears to be uneven. Recheck center link of chain is mounted on

center cog. Make sure chain is fully pressed in, particularly the center cog.
