Hey guys, I;m building a 600 LE, and the alignment on the bearing blocks is starting to wear me out. I get them pretty good using the main shaft, then one final nudge..and it gets sticky.I've gone around like a wheel..but it still gets sticky.

I wondered which way everyone had them installed. I have the top one w/ the writing going forward, and the 2nd one the same way.

Thanks

I dont know about the bearing blocks for the le since i dont own one but if they are anything like the regular Align metal blocks then the top block should have the writing facing up and the bottom block should have the writing facing down. As far as Alignment of the bearing blocks i just tighten them without the shaft installed and see if it drops like that if so i leave them alone and go about the rest of the build but if you are having problems lining them up check and see if the rest of your frame is strait first. If it is try putting them in with no shaft and if that doesnt work put the shaft in place and slowly tighten them up a little at a time as not to tweak the blocks or the frame.

Trying not to put them in the dirt.

I'll try flipping the bottom block over. I was already past this, just getting ready to install the servo's, and thought the main shaft could be better..should've left it alone!

I personaly have fought with the same alignment problems. What i found in the end was everything you do to the frame plays a small part in the alignment of those bearings so i wait until every thing is installed and attached and do a final tweaking of the bearing blocks until a spare shaft i have fits perfectly. It takes alot of fiddling with to get it there but my Main shaft bearings have lasted alot longer since going through the pain of aligning them.

Take your time and get this right, it will make your bearings last a long time. This is the exact reason why most have problems with premature bearing failure. I can usually get the top two blocks perfect, I then oblong the holes for the lower bearing block in the direction it needs the correction. Quite honestly this little detail takes the longest of any part of the build. I have some original bearings one of my birds that's two years old now. It fortunately is my only 600 that hasn't met Terra firma, which definitely puts a damper on bearing life!! lol

Thanks guys..I started over, and found the lower was the trouble maker!!! It was pulling the shaft towards the rear slightly.
