Slash 4x4

Been doing a few simple things to the 4x4 Slash to keep it going nice and smooth.

If the bearing rotates smoothly, DO NOT attempt to clean the dirt away from bearing or spray any sort of liquid to get the dirt off. The dirt will just go into the bearing and ruin it.

These pictures were taken a few days after we got the Slash 4x4. The differential housing is not sealed off very well.

Sealing up the differential case:

Get everything cleaned around the housing and apply some sort of gasket material. (I used a non-drying gasket maker) If you get the right grease that should be all that is necessary for the ring and pinion.

Here is what the differentials look like after 3 months. Nice and clean!

The grease on the ring gear is still in place after months of driving and the bearings are still smooth. Hate to over emphasize it, but leaving the dirt there seems to be the secret.

After severely overheating our motors (the rotor completely lost its magnetism) we put on these associated heat-sinks. I strongly recommend using a Heat Transfer Compound between the two surfaces, you can see how it squeezed out the side.

Transponder Mounting:

There are two holes that line up perfectly for these transponders. We cut the rubber servo grommets in half and used them as shock absorbers.

RPM Suspension Arms:
These will interfere with the drive shafts in the rear if the suspension droops to low, you run the upper hole in the rear hub carrier, or a combination of the two. 

The remedy is to carve this section of the suspension arm down.

Permanent (red) Loctite can be used to prevent the screws from backing out of the plastic parts.

Differential Tuning:
Take the differential apart and get everything cleaned up.

Install the O-ring into the ring gear or housing first, NOT on the spider gear.

Glue the bearing to the metal surface (Green Loctite).

Advanced preventative maintenance:

Drill + Tap 2mm threads in between the bearings on your steering knuckles and hub carriers so you can oil the bearings from the inside.

Spur Gear (center differential):

There was slop between the spur gear and the differential housing and putting some RTV silicone sealant seemed to help.

Same spur gear since December 2011.
