1/12 scale axle trouble
This weekend I began building my new Trinity Switchblade 2002 edition, and I have been having a weird problem with the rear axle. When I put the bearing into the plastic oval piece, and place both over the axle, it spins fine and freely. However, if I then put the plastic oval piece into the right side aluminum pod bulkhead, and put the axle through, it does not spin nearly as well, and has some binding/rubbing. I thought that maybe the plastic piece holding the bearing was being squeezed by the bulkhead, and so I shaved a lot of material off of the plastic, but the problem continues. I never had this issue with the IRS pods on my 12L3, so any ideas on how to fix this problem would be appreciated.

Thanks for the idea, but where can I find a reamer long enough to do that? I have the Associated one, but that wouldn't be nearly long enough to reach across the pod.

2tenths,
Trinity might still sell one, the one he is taking about doesn't have a taper to it. It is straight and fits across the pod. Talk to Debbie about ordering one. If your really carefull you can do each individually but dpowell's suggestion is best.

Thanks Steve. Because I don't have the right reamer, I used the AE one to take out some center material on the one bad ride-height spacer plastic bearing-holder thing, and it helped the problem a little. I also tried aligning the rear bulkheads. However, the problem of binding also occurs when only the right bulkhead is used (pulled out of the car), indicating that the problem is not only the bearing alignment of the rear axle. It's not really a big deal; it's just that my 12L3 is freer. I sure hope people show up on Fridays or Saturdays for 12th scale at Rain (not just Wednesdays like last year).

try sanding the outsides of the ride height adjusters. they are a very tight fit and the crush slightly when you press them in. Apparently this is enough to bind up the bearing.
This also makes if easier to install and remove them.
It will also help with alignment of the bearings. the reamer idea is a good one and I've seen people do that.

LIGHTLY sand the edges of each ride height adj. Then assemble the rear pod leaving all the screws slightly loose, press in the ride height adjusters and the bearings, then slide the axle through the bearings. Tighten down the pod plate screws in an x-pattern, remove the axle and bearings, then ream out the ride height adjusters. By doing it this way you ensure that everything is properly aligned.
