Pack 3, Assembling the lower left arm

[Mark A]

Assembling the lower left arm

 

Start by locating TR-3-18 and TR-3-19. As well as 2x PB2.3x6mm screws. This creates the “left wrist.’ Screw the two halves together, and then slip TR-3-46NEW over the assembly. TR-3-46NEW is located in a separate bag. Make sure to use this, as the previously supplied part does not allow full function of the wrist joint.

Next, find TR3-13 and screw the previous assembly onto the plate using 4x PB2.3x6 screws. (step 2)

For step 3, you’ll need the upper arm assembly from pack 2. Locate parts TR-3-10 and TR-3-11, and use 2x PB2.3x6 screws to secure the halves onto the elbow joint

.

 Next, for step 4,  locate parts TR-3-09 and TR-3-12, along with 2 more PB2.3-6mm screws. Attach these two parts as described. In step 5, you attach 1 small part to the elbow.

 

Step 6 creates the “forearm” and requires TR-3-03 and TR-3-04, as well as 3x M3x12 bolts, lock washers, and nuts, as well as the assembly from step 2. Screw the parts together as depicted, taking care that part TR-3-46NEW is positioned correctly.

Step 7 adds a “cuff” to the lower forearm, with 4x  PWM2x5.5mm screws.

Step 8 will require a bit of CA glue to secure part TR-3-15 to the “sleeve” TR3-01. Apply in the 4 areas indicated by the drawing in step 8A. Step 9 is an immediate follow on where the assembly from step 8  is screwed to the lower forearm, with PWM2x5.5mm screws.  

Steps 10-13 covers more parts that comprise the outer covering pieces (TR-3-07 and TR-3-08)) that are  screwed to the forearm, and in step 12, the mating piece TR-3-07 is screwed on from the other side.

Lastly, in step 14, the final two parts are added to the forearm, using CA glue applied in 3 places as indicated in the build guide.

Instep 15, the hand is press fit into the socket, resulting in a complete left arm and shoulder!

 

NOTE; Other than the required parts substitution, there is nothing tricky about this parts pack. The assembly is superbly engineered, and the quality of the parts is second to none.

Where the heck is the bag with the replacement part for TR-3-46!?!  There are plenty of warning not to use the packaged part, but no indication of where the mysterious bag is with the replacement.  Someone please help!!!
