Dual Extruder Part Problem

[Explorer71]

I got the dual extruder upgrade a month or so ago and finally had time to try to install it. I got as far as page 3 where it says to put the belt clamp on the belt and fasting the mounting plate to the clamp and tighten the bolts. Half of the bolts will not tighten. One of them slides all the way into the hole with no resistance. The other bolt will turn in the hole but has nothing to grab and will not tighten. A third bolt tightens a little and then just keeps on turning. Only one of the bolts tightens at all. It looks like the holes in the belt clamp are drilled out to large. At this point I have the extruder head completely disassembled and the printer is not usable. I either need larger bolts or a new belt clamp with the right size holes. HELP !!!

The belt clamp uses captive nuts on the underside -- you're not forgetting those, are you?

If the plastic has stripped out around them, wedge a screwdriver alongside the nut while you tighten it down, until friction takes over.

I never looked at the bottom of the belt lock. Apparently some of the nuts got pushed out. Thank you for straightening it out for me
