AX90046 SCX10 II Jeep Cherokee Kit Build Series – Part 4

AX90046SCX10II_JeepCherokeeKit_Build_Series_Part4
We’re moving into a tricky area of our SCX10 II Build, the shocks. The AX90046  comes with the licensed Icon Vehicle Dynamics aluminum body oil filled coil-over shocks (AX30103) which are the preferred shocks for serious off-roaders. The shocks go together nice and smooth and offer excellent performance on the trail. Of course we do have a few tips to pass along to help you with building them so let’s get right into it.

GET READY
Axial SCX Icon Shocks 1
Like we’ve suggested in previous posts, it’s a great idea to get all the parts together that you’ll need to build this part of the kit. For tools you’ll need a pair of side-cutters, long nose pliers and we suggest TLR shock shaft pliers to hold the shafts. You can find TLR pliers HERE.

STEP 1
Axial SCX Icon Shocks 2
First up, we need to install the spring pre-load nut on the shocks. Using side-cutters, cut the nut off the tree and screw it onto the shock with the flange side facing the logos. Screw the nut on several threads so the shock caps can be installed later.

STEP 2

Oh, this is a fun job! Installing the e-clips on the shock shafts, watch out, they could go flying if you are not careful! With your needle nose pliers, snap the e-clip into the lower slot on the top of the shock shaft. Then slide your piston over the shaft and secure the top with another e-clip. Take your time here so you don’t lose any clips or damage the piston with the pliers.

STEP 4
Axial SCX Icon Shocks 4
Here is a tip you may not know. Before installing the o-rings in the shock, place them in a plastic bag from the kit followed by a few drops of shock oil and make sure they’re coated. This helps the shock feel smoother when completed.

STEP 5

Why are we showing you the shock o-ring spacers in a stand-alone photo? It is critical to cut the spacers from the tree without any extra plastic flashing. Extra plastic here could cause unwanted friction in the shock.

STEP 6
Axial SCX Icon Shocks 6
It’s time to install the shock seals into the bodies. Slip one o-ring into the base of the shocks, followed by the plastic spacer, then another o-ring followed by the lower shock cap. Tighten the lower cap firmly. After the seals are assembled, place a dot of oil on the shock shaft threads and slips the shafts into the shock bodies.

STEP 7
Axial SCX Icon Shocks 7
The lower shock ends need to be screwed onto the shock shafts. Do not use knurled pliers to hold the shaft, this could damage the shaft which will tear the o-ring seals. We suggest using shock shaft pliers to hold the shafts while installing the ends. Then pop the pivot balls into the shock ends.

STEP 8
Axial SCX Icon Shocks 8
You’ll need to prep the top shock cap before you fill your shocks with oil. These Icon replica shocks come with faux reservoirs for scale style. You’ll need to place the Icon logo on the reservoirs and then screw them to the shock caps. You’ll also need to slip an o-ring seal into the top of the cap. Watch, the o-ring may fall out. If this happens, placing a drop of oil in the cap can help keep it in place.

STEP 9
Axial SCX Icon Shocks 10
Fill the shock bodies with oil. After you fill the shock with oil almost to the top, take the shock shaft and slowly cycle it up and down. This will release any unwanted air.

STEP 10
Axial SCX Icon Shocks 11
Before screwing on the shock cap, push the shock shaft almost all the way up to the top.

STEP 11
Axial SCX Icon Shocks 12
With the shock shaft at the top, screw the shock cap onto the body and wipe off any excess oil with a paper tower. When the shock is assembled, the shock shaft should be able to be pushed all the way up to the top. If you have a large gap of shock shaft showing, you will have to bleed out excess oil. To do so, loosen the cap a few turns and push the shaft up. Oil should bleed out. Once a little oil bleeds out, retighten the cap and try it again. Keep bleeding the shock until the shaft reaches the top.

STEP 12
Axial SCX Icon Shocks 13
We’re getting close to wrapping up these shocks! Slide the springs over the shock bodies and slip on the shock perch. Snap an additional pivot ball into the shock caps.

Here’s how your shocks should look once completed. Note that there are front and rear springs so place them on the vehicle later accordingly.

Build The Perfect King Shocks

Building_ThePerfect_King_Shocks

When it comes to building shocks on an RC kit, many builders start to cringe. It’s not a favorite task for many, however building your shocks properly is a must if you want your suspension to perform. We’re working on a RR10 Bomber for some future video action shoots and decided to take some extra time to take photos to show you just how to build the King aluminum shocks that come with the kit. Here we’ll show you all of our tips and tricks that will result in a high performance shock that will give your rig the best handling possible.

YOU’LL NEED
Shock Shaft Pliers (TLR99101)
5.0 Nut Driver (Set: DYNT2010)
Shock O-Ring Grease (TLR77002)
Competition Silicone Shock Oil (TLR74020)
Paper Towels

STEP 1
Axial King Shocks 1
It’s best to take the time and lay out all of your shock components nice and neatly so you have everything in front of you and nothing is left out.

STEP 2
Axial King Shocks 2
We’re going to start with the cartirdge assembly. Carefully cut them from the parts trees and slip the clear o-ring over the threads and seat it in the lower slot.

STEP 3
Axial King Shocks 3
Don’t jump right into installing the shock o-rings in the cartridge. Before you do so, here’s a tip. Use a shock o-ring grease such as TLR77002  to grease the o-rings. Place a small amount of grease in a plastic bag and then the o-rings. Work the grease onto the o-rings so they’re well coated.

STEP 4
Axial King Shocks 4
You’ll also need the cartidge spacers and caps to finish the cartridge assembly. It’s best to cut the parts off of the tree using a hobby knife. Cut as close as you can to the spacers so there isn’t any extra material from the tree on the spacer. Extra material here could cause a binding in the cartridge.

STEP 5
Axial King Shocks 5
Place a greased o-ring in the cartridge, followed by the spacer, followed by another o-ring.

STEP 6
Axial King Shocks 6
Snap the cartridge cap on and make certian it is perfectly seated in place. If the cap isn’t completely snapped on, it could possible come apart during use.

STEP 7
Axial King Shocks 7
Now it’s time to install the pistons on the  shock shafts. In your RR10 kit, there will be delrin pistons in the bag. Use these. Place one washer on the shock shaft, followed by the piston, followed by another washer and then the retaining nut. Use shock shaft pleirs to hold the shaft and use the 5.0 nut driver to snug the nut into place.

STEP 8
Axial King Shocks 8
Once you’ve tightened the nut, make certain the piston just barely spins on the shaft. If you tighten it too much to the point it can’t move, you may have possibly “mushroomed” the piston and it could possibly bind in the shock body.

STEP 9
King SHock
Slip the assembled shock shaft/ piston into the cartridge and thread it into the bottom of the shock body slowly. You’ll want to completely screw the cartridge in slowly until the o-ring can no longer be seen and the cartridge is tight.

STEP 10
Axial King Shocks 9
Slide the bump-stop on the shaft and screw the shock end onto the shaft until the top of the end meets the unthreaded portion of the shaft. Using shock shaft pliers here is a good idea.

STEP 11
Axial King Shocks 11
Time to install the pre-load collars, but first you need to slip the black o-rings into the slots inside the collars.

STEP 12
Axial King Shocks 12
When threading the collars onto the shock body, it’s a good idea to put a drop of oil at the top of the threads. This will allow the collars to screw on much easier.

STEP 13
Axial King Shocks 13
We’re getting there. It’s now time to fill the shock with oil. Instead of using the kit oil, we’re going to use a competition grade oil from Team Losi Racing to fill the shock. With the piston at the bottom of the body, fill the shock body with oil to the top.

STEP 14
Axial King Shocks 14
Axial King Shocks 15
This is a critical step. We have to cycle out any air trapped under the piston. Slowly push the shock shaft up in the body. Don’t let the piston go past the oil at the top. When the piston nears the top, pull the shock shaft back down and air bubbles should rise to the top. Continue this process until all of the trapped air is gone. If there are fine bubbles in the oil, set the shock aside and wait for the air bubble to come to the surface.

STEP 15
Axial King Shocks 16
Seat the shock bladder into the cap. Slip the bladder in and using a fine blade screwdriver or similar object, make sure the bladder is seated perfectly in the top of the cap by pushing on the edges.

STEP 16
Axial King Shocks 18
Top off the shock with oil if necessary. The oil should be near level with the top of the body.

STEP 17
Axial King Shocks 20
Slowly push the shock shaft to the top.

STEP 18
Axial King Shocks 21
Now screw the shock cap on. Some oil should seep out of the sides. Tighten the cap firmly.

STEP 19
Axial King Shocks 22
Once the cap is tightented, the shaft should slide out a little bit. Cycle the shock shaft in and out several times to make sure it has a good feel and there isn’t any binding.

STEP 20
Axial King Shocks 23
If the shock is built correctly, you should be able to push the shock shaft all the way to the top. If there is a lot of shock shaft showing, you have what’s called hydro-lock and this will cause handling problems. You may need to bleed some additional oil out of the shock. Loosen the cap, push the shock shaft in all the way and tighten the cap again. This should bleed out some oil. Repeat the process until the shaft goes all the way up.

STEP 21
Axial King Shocks 25
Almost done, slip the appropriate spring over the shock body and slip the lower shock perch into place. Pop the ball end into the shock eyelets and you’re shock is assembled!

FINISHED
Axial King Shocks 24
Your shocks should now be assembled and ready for installation on your rig. You’re not done yet. You’ll still need to adjust your pre-load collars to set your vehicles ride height. Use the suggested collar settings in the manual as a starting point. Because the weight of the equipment used in a rig may vary, small adjustments may need to be made to set your vehicle to a ride height that will work for you.
