RC4WD 870K Loader - Warning - Potential axle problems

[Rimrock]

Hi,
The axles are just poorly designed and manufactured. I've got 4 of them on my workbench now. The bearing supports in the castings are not machined and thus not precise (which is difficult and time consuming concerning castings, due to the task of aligning and fixing of the pieces to the machine table) Diff. gears are castings with less of more precition. The bolted connection of axle house and the hub/planet gear supports in the wheels, are a weak link, and the 4 hard to reach bolts in each connection will over time come loose, if not proper thread sealer is used. The problem of applying much thread sealer is that one can easily ruin the bolt heads when trying to unloosen the bolts again...
The machine is designed and produced in China, or Hong Kong, rc4wd is just a dealer and can just replace old crap with new crap..I guess so machines by luck have some higher quality axle/gear casting parts, but it seams to be a lottery what you get in a new machine, or as replacement parts..
I am currently developing new axle units for one of my friends loader, using high end CNC machined truck axles and adapting the loader's hubs/planetary gearings to them. Will come back with some more info and pictures later on..

The use of a soldering iron on the head of the bolt to warm the bolt up & soften the thread lock works with good results, it takes several minutes.

No truer words spoken there!... and my luck 4yrs ago with their excavator was crap right out of the box with a bad radio & faulty electronics. RC4WD's warranty was 10% off replacements parts... why would I spend more money on crap parts that a company won't warranty within 30days anyway??!!!

I guess it's good for the Chinese that they're willing to work for next to nothing b/c what they offer to the world for goods isn't worth a shyt either.
