Last post on this thread was some time ago but I found it very useful as I have just stripped down a Scott 3200 tailwheel that was fitted to a Jodel D140. The reason I got involved is because the tailwheel was free castoring and as my SuperCub is being rebuilt, I lent my Scott 3200 to the owner whilst we had a look at his.
We stripped it down and it was a bit of a mess. The dowel that stops the bottom bush rotating was flush and there was no pin holding the butterfly spring, furthermore, the hole where the pin should be was somewhat oval.
Getting a new pin would not solve the problem so we went down to the machine shop and the guy sorted out the problem.
Firstly he drilled under the dowel keeping the bush in place and punched it out and fitted a new stainless one.
He then drilled out the oval hole and made up a new pin that was stepped, the wider part matching the new oversize drilling. The original 3/16" hole was retained in the section between the gap and the centre bushwhich means that the butterfly spring and shims do not have to be drilled oversize. To make assembly/stripping easier, he tapped a thread in the new pin so that a 3mm screw could be attached so that it was easy to get in/out.
Have ordered a new pair of bushes, dust seals and butterfly spring so it should be back in action soon.
Final thought is, how much grease is needed. It would appear sensible that it should be re-assembled with a smear of grease on the relevant components but pumping it full would seem unnecessary. The whole assembly functions well dry and would only seem to need a hint of lubrication. Is it packed with grease to keep the water/dirt out?
