TANKS’ TORSION BARS Read instructions carefully before assembly Tools Required

1. M3 Hex Wrench 2. 5.5mm Wrench 3. Long nose pliers 4. Small hand file 5. 3mm drill bit

Part number 16T021 -- Tiger I, Panthers and Jagdpather, there are 16 short Torsion Bars Part number 16T022 -- King Tiger and JagdTiger, there are 18 long Torsion Bars Part number 16T022 -- KV1/2, there are 12 long Torsion Bars. BLACK springs for LEFT side,

SILVER springs for RIGHT side Part number 16T040 – Leopard 1A4, there are 14 long Torsion Bars. BLACK springs for LEFT

side, SILVER springs for RIGHT side Ground clearance (distance from the bottom side of lower hull to the ground) is limited by the tension of the tracks and the total links per tracks

When storing a tank, it is best to let the tank rest on a stand on the bottom of the lower hull instead of letting the tank rest directly on the wheels, which will weaken the suspension. This applies to any type and brand of suspension systems.

Torsion Bar Part Number

01 – Collar for locking A and road wheel arm end (with M3 set screw x 1pc) 02 – Shaft 03 – Collar for locking 02 and torsion spring lock (with M3 set screw x 1pc) 04 – Torsion spring 05 - Fixed collar for torsion spring and Torsion Bar Stay 06 - Hex bolt and spring washer assembly

On the Torsion Bar Stay, bend all the tabs down, as shown in the picture. The purpose is to make space for bolt 06.

1

Try fitting in bolt 06 for space. It is not necessary to bend the tabs down flat.

2

Use a 3mm drill bit to enlarge the all the holes at the Torsion Bar Stay. This is for the bolt (06) to pass through.

Be extremely careful when drilling, use safety goggles.

3

Inspect all the holes, clean and remove any burrs from drilling with a small hand file. Use the bolt (06) to fit in all the drilled holes, to check the holes have enough space.

4

a. Install all Torsion Bars onto the 2

pieces of Torsion Bar Stay. 16bars – Tiger I, Panther and Jagdpather 18bars – King Tiger and JagdTiger b. Apply light thread lock at bolt (06). Using pliers holding collar 05 and a 5.5mm wrench holding bolt 06, make sure that it is tightly screwed.

c. At this time, do not tighten the set screw at collars 01 and 03 yet.

d. Make sure that all the set screws at 01 and 03 are facing upwards (like in the picture), so that it will be easy to tighten it when tuning is completed. e. Except for the set screws directly below the bottom of the gearboxes, face the set

5

screws slightly off the upwards position. Because when the wheels torsioned, the bars’ (bottom of the gearboxes) set screws might scratch the gearboxes’ bottom side housing.

Screws to face upwards

Go to see Section 2 Pg. 8, if installing for Panther and Jagdpanther . A minor modification is needed for back panel.

a. Assemble the 2 strips of Torsion Bars Stays with Torsion Bars (from Step 5) into the lower hull.

b. Install all the stock road wheels arms into the lower hull. Slide in all the flat ends of 02 (A) into the slot of the road wheels arms.

c. Use long nose pliers, grip on the shaft 02, move all the flat ends of 02 until it is fully into the slots of the road wheel arms, like B.

Apply some lithium grease around the road wheel arms which in contact with the Torsion Bar Stay, so that during suspension, the resistance will be less. Move all collars 01 to cover the ends of the road wheels. Make sure 01 is not too close to the Torsion Bar Stay, or else there will be resistance when arms swing during suspension. Using M3 hex wrench, all the set screws for 01 can now be tightened. Install all the stock road wheels and the idle wheels.

OPTIMUM ADJUSTION OF THE TORSION BARS

-------------------------------------------------------------------------------------------------------------------------------------------

Positive Torsion: when the wheels swing upwards

Negative Torsion: when the wheels swing downwards

8

Preparation before adjustment:

1. Temporary install the Transmission Units and the tracks. 2. Use any solid object at the bottom of the lower hull to pre-determined the ground clearance

and also a reference for torsion adjustment.

a. Let all the road wheels come to rest, at the lowest natural level. b. Using M3 hex wrench, tighten not too much on the set screw at collar 03. The torsion

bars will have the tension action once screws are tightened. c. Use your fingers to do a positive torsion and feel for the torsion force for all wheels. d. If too light, loosen set screw at collar 03 and adjust the wheel towards negative torsion,

then tightened the screw. e. Check for torsion again. If not enough torsion, repeat the step from (d) again. f. When all wheels are checked to in good torsion force, adjust the front 2 and rear 2 road

wheels for slightly more negative torsion. Because it is these wheels that will have to take the hardest torsion during running.

g. Once a confirmed adjustment is completed, tightened all set screws at collar 03 to the fullest.

h. Do NOT apply thread lock onto the set screws as tuning might be needed periodically or when needed.

i. Use a brush, brush a thin coat of lithium grease on all the torsion bar assemblies. j. Do a few test run to be sure of the torsion. If further fine tuning is needed, use the

5.5mm wrench to turn bolt 06, the whole torsion bar assembly will move. http://www.youtube.com/watch?v=CMdfsBfAO2E (Youtube for reference)

k. Continue with the assembly of the tank.

Section 2 Minor work needed if installing onto Panther or Jagdpanther

The rear last right side torsion bar will be slightly block by the bottom part of the stock plastic back panel.

1

There is about 5mm of excess plastic blocking the Torsion bar. Measure and mark on the part.

2

Cut away the excess plastic. Continue to install the Torsion Bar at Step 6b,

Pg4.
