XRAY - Model racing cars

In my posts about settings and tech-stuff I may sound allready like a semi-pro.

... BUT ...

I'm wondering how often I should take apart, de-lube and re-lube eg.:

- Bearings
- Dogbones
- One way diff
- Rear diff
- Alu Shocks
- etc.?

I ran the new FK04 now about 25 - 30 times for 7 minutes in dry conditions.

Please give me some hints?

Thanks in advance...

Ya.. I was wondering the same thing. Mostly about the rear diff tho. The bearings don't seem like they require much maintenance as they are sealed, but I've had around 30 runs and still haven't taken apart my diff yet. It still feels silky smooth and hasn't given me any problems what-so-ever. Should I take it apart and rebuild it anyway?

Every 2 to 4 weeks I completely disassemble the entire car and clean & relube all of the joints, bearings, diff/one-way and shocks. I also put the arms on my setup board to make sure they are still flat and not warped.

Each week, after the race day, I do the following drivetrain/suspension checks:

* Detach each shock, take off the spring and check for air in the oil
* With shocks detached, and the chassis on the stand, I lift each arm up to approx full suspension travel height and let it drop to make sure it is still free. I also move the arms frontwards and backwards on the pins to see if there is too much play (more than .25mm). If so, I loosen and retighten the pin carriers to give just enough play for the arms to rotate freely.
* Rotate rear wheels to check rear diff smoothness (is that a word?)
* Take off front belt from one-way pulley without any dissassembly. Check drag of all front bearings and the oneway by spinning each front tire independently. If one side is not spinning freely enough, I disassemble the knuckles first and check their bearings as they are more likely to have become dirty or even gone bad. If the knuckly bearings are fine I detach the bulkhead on that side and check/fix the bulkhead bearing.
* Detach each rear hub and check the drag of the bearings by rotating the hub in my hand at an angle to see if the axle swings very loosely with a pendulum effect.
* With front belt off, rear hubs detached and motor/pinion out, I spin the spur to check the drag of the layshaft bearings and rear bulkhead bearings. If it doesn't seem right, then I detach the left rear bulkhead and check/fix the bulkhead bearings first as they are more likely to be dirty or bad.

Theres probably more, but this is all that comes to mind right now. Of course I check the chassis tweak (on downstop blocks) and foam tire wear after each run.
