Another Willys Jeep (1/20 scale) Chassis and Drivetrain

Willys Jeep chassis and drive train.   The chassis provides the frame and pretend suspension for a rolling model of a Willys Jeep.  Broke it in two projects, the body and accessories to follow.  All parts are PLA except tires and leaf springs.

Body and accessories here

Somewhat challenging to print due to scale and small size of some parts.  A bit of overkill on some of the parts, but you get a rolling model with a pretend suspension.

Assembly

Test fit everything, clean up holes to make sure things move as expected before gluing unless you don't care if it rolls.

1) Attach front and rear Leaf Springs , shackles, and shocks to frame using bits of filament.  One side of the leaf spring slides into a pocket and can be secured with a touch of glue, the other into a shackle.  Shocks have a slight offset make sure to orient them with the offset edge towards the frame.

2) Slip the front and rear axle through the loop on the leaf springs.

3) Drop the engine in and install the front and rear drive shafts.  I left them loose, no way they will fall out.

4) glue the engine mounts to the frame.

5) Glue the tires on the wheels.  Tires were printed in TPU.

6) Slide spacer over rear axle, then rear wheel and secure with pin and touch of glue.

7) Glue the FWPivot 1 to the front axle ensuring it is oriented with the pin hole vertical.

8) Install the FWPivot left and right with a piece of filament to the FWPivot1 after the glue is set.

9) Add wheel to FWPivot and secure with pin and bit of glue.

10) Install the tierod to the FWPivotR and L.  It just slips in.

Yay, you are done.
