You need to get the mech steam motor and the mech crank. In a garage by Sullys is unfinished mech. Use your two mech items besides it and you then have built the mech.
The unfinished Mech that Zack was working on is in the garage next to Sully's. You need the Mech Motor and Mech Crank to finish it.In the garage next to sully's shop on the left side of the island.
The Mech Crank and the Mech steam motor are needed to complete the Mech walker that is in the garage next to Sully's. It was being rebuilt by Zack. The Mech motor is at the far right in the production zone. (Farther up is the Living Quarters key, in a closet behind the monster plant.) You will need the dirty beaker from the Museum and the Rubber Mallet from Sully's trash box. Once you have the motor and the Living Quarters key, get the Mech crank from the vines above and left of the Living Quarters, and you can rebuild the Mech. Its Weed Wacker is the only way to enter the storage rooms at the far left.
Along with the Mech Crank, it completes the Walking Mech that is in the garage next to Sully's. To get the Crank, you have to go through the Living Quarters to reach the high vine at upper left.
Go left along the vine and pick up the Mech Crank. Along with the Mech Motor you recovered from the Production Zone, use it to finish building the Mech walker.
