Catrike 2007 Trail Owner's Manual page 18

Install the chain.
• Start at the chain rings in the front of the trike. Run the chain through the front derailleur;
between the main cross member and the tie rod; through the upper chain tube; under the
idler wheel; over the rear cassette; through the rear derailleur and back through the lower
chain tube. Now you can use the MasterLink to connect the chain together.
TIPS: It's easier to thread the chain if you immobilize the crank. This can get messy! Protect your work surface and keep paper towels
handy. It's easy to thread the chain through the rear derailleur cage incorrectly. Make sure the chain runs cleanly through it, and not over
the retaining tabs.
Adjust the chain length. To do this, shift onto the largest cog on the rear and the largest chainring in the front. Pull the chain taut, so that
the rear derailleur cage is fully extended. Then add two links. That will be close to the ideal length for the chain. Use the included
PowerLink to hold the chain together.
There's a trick to opening a PowerLink that seems to elude many people. First hold the link
between your thumb and forefinger, and push the plates together (towards one another).
Then slide them in opposite directions, as if you were snapping your fingers. Opening a
PowerLink should be easy...if you find yourself reaching for a pair of pliers you're not
doing it correctly.
Note the chain routing above there is a chain guide tube
(return) running beneath the cross member. The drive
part of chain runs underneath the black guide pulley
and over the top of the chain ring.
If your Catrike will be used by more than one person, feel free to use
two MasterLink so that the chain can be easily adjusted for other riders:
simply set the trike up for the shorter rider, then insert a piece of chain
long enough to accommodate the taller rider. If this short piece of
chain is between two MasterLinks, adjusting the trike should take only
a couple of minutes. It's a good idea to mark the boom for both length
and orientation for each rider using a Sharpie marker, so that the
setting can be repeated easily.
Just to be clear on what we mean by "two links," check the photo.
Don't forget that the PowerLink counts as one link.

TIP: It's easier to work on a chain under
tension if you create a loop of slack and hold
it in place with a stiff, bent wire, made from
an old spoke or wire coat hanger.
