Hello,
Thanks for advice,
Supplier and seller said that warranty do not cover repair and so on....,
Leica said that it is possible to repair, but can´t say the ammount before
their technician inspect it, and I think that repair and shipping will cost nearly the purchase price (which was 350€), so I decide to repair it by myself :t:.
Yes, brave decision, so it was my first repair of bino :-O
Only tools I used was screwdrivers and pliers.
After opening the cover in middle of focus wheel, I use small wathrepairing screwdriver for dissasembling small pin which was screwed to the brass rings
which was screwed to the central rotor shaft (also brass). After dissasemble of the brass ring from central shaft I get down the outer focus wheel (used as diopter correcting for right eye), and I saw the scale and inner focus wheel mechanism, it was mehanicaly connected to outer wheel by three force screws, after loosen of these three screws I was able to move rotor ring and adjust the left tube to "infinity" by using screwdriver, while the inner focus wheel stay in its position. I spent two hours with adjusting the focus of tube and revealing how the mechanism works. When I adjusted the left tube to make it able to focus to "infinity" ("" is because I adjusted it only experimentall
) I tighten three screws to mechanically connect rotor ring to inner focus wheel. After that I adjust the right tube by pulling the central rotor shaft and turn it by screwdriver. On the picture i attached you can see two plastic half gears which is used for turning central shaft by outer focus wheel. Then I assembled it back near the first step with short pin, and was able to find out which position on scale is setted up to +1d which is my personal correction, and I measured the angle between +1d and finest diopter adjustment setting. So I dissasemble it and turn the outer ring in respect to measured angle, to get the finest diopter adjustment setting at +1d. After that I assemble it and find that the pin which connect the brass rings to central shaft and outer focus wheel did not get after tightening into correct position where the two holes of brass ring and hole in outer focus wheel alling in axis. So I started my micro drilling machine (which I use for printed circuit boards drilling) and make new hole in downer brass ring and outer focus wheel. (Maybe I should measure the angle between brass rings and outer focus wheel and adjust it, but I don´t have taste to spend hour more, because was sunday and want to go birding out.)
Then I put the pin inside new hole and tighten it and gave back cover.
After spend 4 hours, I repair it to better condition that the seller send me.
Now it can focus far, and waiting on clear sky (it is rainy now in Slovakia) for star test which was the main problem of previous condition of focusser and diopter adjustment. I think that the new condition will focus behind stars like other binoculars can.
Warning: Do not repair your binoculars at your own without additional assembling skills (I have 10year skills from electronic manufacture and 10 year from childhood assembling LEGO including Lego Technic:hi
I decide to repair only because it was my last chance- supplier and seller was reluctant, and I know that if I damage the bino I will send it to Leica, because the repair cost will be same, shortly I hadn´t anything to loose with my repair. First repair, decent bino, and success, what else you could wish
In the end I must thank also to designers of Trinovid, that they make easy to repair design, which thinks also on second hand and non waranty owners, like me which could not spend big money on repair. In that aspect it recalls me old european Fords Granada, Taunus or Cortina which my deceased father repair on court with using common toolso
.
