It is not a nice job replacing the bushes, but as with most things on the Europa they are mostly fiddly and play on the mind, but are actually doable in a relatively short time.

To my dismay, I have just discovered that the bushes on the LG08 forks are quite badly worn. Before ordering new bushes, I am wondering if anybody knows of a more durable material from which these bushes could be manufactured.

I shall do something very similar I think except mine will be easier because I still have the top off. Less swearing.

I guess there many different approaches and mine was probably not the best but it made my day. The washer was mounted on a wooden stick (about 1/2=9D x 1/2") A slot was made that hold the washer on place. Tight. You have to press the washer into the slot. It was quite easy to put the washer on the bolt. Same stick (but the opposite side) was used in order to create a long handle to the spanner. A mark was made on the stick so I know exactly how far in the tube I was. The other hand on the bolt. The first tree were quite easy. On the fourth and last nut the washer went off and I had to rig the washer again. ( A small swearing was fired) Best regards Stephan LN-STE Mono ________________________________ Message 3 _____________________________________ Time: 12:25:56 PM PST US Subject: Re: Europa-List: LG08 bushes From: Carl Pattinson The bushes are "oilite" which are impregnated with a lubricating oil (not sure how they get the oil in) - if you need to heat the lg arms to sweat the old ones out they will ooze oil from the inserts. I doubt any other material would wear any less as the undercarriage takes a lot of punishment. Just make sure that you replace the top rubber block spacer plate facing exactly the same way as you removed it - the block assembly can be removed without dismantling but can be rotated through 180 degrees. If you do this the undercarriage wont retract fully and you will be faced with having to disassemble everything. You only make the mistake once - we did ! Ideally you can suspend the fuselage using an engine hoist - rope through the engine mounting frame. Its not a nice job but as David says can be done in a couple of hours. Good luck, Carl Pattinson G-LABS.

I have attached a drawing of our solution which differed only in that the nutplates were riveted to a tube horizontally and 1/4 inch bolts used. (see drawing) It was never submitted as I had a local machine shop that could put out the work for about $300 and make new holes and pins, or if the 3/8 pins weren't installed yet, we could machine the holes to a zero tolerance fit. A drop of Loctite or two and the whole thing stayed solid for so far, 3 years. So we dropped pursuing the idea. Richard's mod 11969 is a perfectly sound solution that should work. I just felt that Redux on the nutplate was a bit tedious when a rivet could be put into a steel tube quickly. I used a 1 1/4 inch tube (Sloppy fit for ease of moving into position into an existing stab, slotted it on the bandsaw, slid it in and marked the holes with a centering punch (inserted into a 1/4 inch tube to center the punch on the hole and gave it a try. A $10 experiment, that works, but it too is tedious. When Roger Bull came out with the Loctite solution and got it all approved, I sure liked not having to go through approvals when what he did works. You know us Yanks, instant gratification.

After a short while the play was back. My assembly was perhaps a bit tighter then normal so the Loctite did not penetrate enough. In order to get rid of the play I made =93special=94 washer, situated inside the torque tube. Now it was possible to tight the tubes hard together. The result was a zero play system. Complete solid for 5 year (340 hours) . I know another builder that has solved the play in the same fashion with complete success. Here is draft drawing that shows the parts involved. In my case it was only necessary to change the outer bolts: http://aero2012.scassel.se/Images/tailplanemod.PNG It is necessary to create a spanner with looong shank. I used a wooden stick and strapped the spanner to it. After 30-40 minutes and some swearing (not much) it was tight, very tight I may add. Additionally I made a thin black line, 4-5 cm long, on fuselage when TP trailing edge was fully down, parallel with TP skin. This reference line makes it very easy to catch very small play over time. So far the TP is still on the reference line. I check this on every pre flight.

Further more you could increase and have the say two 1/3rd moons, with two drilled recesses in the back and say two 1/2diameter springs slipped in-between the two part moons . To fit just squeeze the two 1/3rd shaped moons together and pop into the end of the tube , now its holds itself in place . Now you can attach a piece of wood slide it down the tube twist it about and line the holes up then pop the bolts in and tighten up. As for the 2 little springs leave them there, or take another thin piece of wood push down the tube and push them out, as they have done there job, and use them again for the next set of 1/3rd shaped moons you are going to slid down the tube to do the next pin hole.
