Hey ... I want to fab some motor mounts from OEM LCA rubber bushings. Similar to MORE mounts or Rusty's mounts -- they both use LCA rubber bushings.
Here is a pic of what I want to make:
The problem is I can't find a tube to press the bushings into. The outer diameter on the LCA bushing is 57 mm (2.244 inches). I measured that with a caliper and confirmed it with Moog tech support.
But ... it's hard to find a tube that will accept that bushing. I've looked at tubing, plumbing pipe, and exhaust pipe. If I go with commonly available tubing, options are:
- 2.5" OD - 0.250 wall - 2.000" ID
- 2.5" OD - 0.120 wall - 2.260" ID
- 2.5" OD - 0.095 wall - 2.310" ID
- 2.75" OD - 0.25" wall - 2.250" ID
Metric sizes are much harder to find.
The closest size is the last one with 2.250" ID. But that will be too big, right? 0.006" of slop is definitely not a press fit. And 2.000" is too small, right? Remember, the bushings already have a metal sleeve on them. Rusty's and MORE both keep that metal sleeve on the outside of the LCA bushing. The other sizes are too large.
Any ideas? I'd like to buy some off-the shelf stuff for this. Anybody else ever made LCA bushing motor mounts? Anybody ever measured the ID of the receiver tube on a MORE or Rusty Mount?
Thanks.
