ymc226 Posted April 23, 2012 Share #1 Â Posted April 23, 2012 Advertisement (gone after registration) I'm getting a replacement lever that fell off my MP from Leica parts NJ. What type of wrench clamp (size) or other type of tool would be best to put it on tightly? Â It's black so I don't want to scratch it. Link to post Share on other sites More sharing options...

jaapv Posted April 23, 2012 Share #2 Â Posted April 23, 2012 You can order the proper tool from Microtools. Link to post Share on other sites More sharing options...
pico Posted April 23, 2012 Share #3 Â Posted April 23, 2012 Jaap gave the answer. Microtools. Â Please do not try to over-tighten. A fastener that has been over-torqued is already half broken. Besides, the spanner will likely slip. Â Very best of luck Link to post Share on other sites More sharing options...
ymc226 Posted April 23, 2012 Author Share #4 Â Posted April 23, 2012 Thanks. I've looked at Microtools and looking at the MP VF preview lever, would a flexi clamp be the best tool? If so, do I measure the diameter of the circular "screw on" part of the lever as to size the clamp properly? Â Flexiclamp, Brass 6.0mm Link to post Share on other sites More sharing options...
jaapv Posted April 23, 2012 Share #5 Â Posted April 23, 2012 It depends. I do not know if the MP uses the modern flat screw which needs a 10 mm Flexiclamp or the older two-hole one which needs a double-pointed wrench. There may well be more models of screw about. Leica has used a number of designs. Link to post Share on other sites More sharing options...
pico Posted April 23, 2012 Share #6 Â Posted April 23, 2012 You might wait until the camera comes back to be certain of the type of faster they sent you. My guess is that you will need the adjustable spanner. Â Detents are ~6mm apart, post type are ~8mm in diameter. Leica has at least three different kinds of fasteners for the vewfinder lever. Looking at the M cameras here - one that can only use the Flexiclamp (on an MP4-P), one that can use either the spanner or Flexiclamp, and one that can only use the spanner because the edges of the screw are tapered to the top (on an M4).

doubice Posted April 23, 2012 Share #7 Â Posted April 23, 2012 Advertisement (gone after registration) As an alternative to spanner tools, you can use a piece of rubber (old bicycle tire or a suitable eraser) to tighten the part. Press down while tightening - no danger of anything slipping and doing damage. Â Good luck, Â Jan Link to post Share on other sites More sharing options...
ymc226 Posted April 23, 2012 Author Share #8  Posted April 23, 2012 Looking at my other MP, the VF preview lever has 2 shallow indents on the front surface just as in this MP on MIR. Is this what is meant by the 2 holes? http://www.mir.com.my/rb/photography/companies/Leica/Leica-M3/Leica-MP/MP-Titan/index.htm  Would this need a special tool that would rest in these 2 holes to allow tightening?

doubice Posted April 23, 2012 Share #9 Â Posted April 23, 2012 Yes, those are the 'two holes'. It is rather tricky to use the spanner tool - there is always a risk of it slipping and marking the camera or, overtightening. I strongly recommend using a thin piece of rubber to tighten it - have done it many times in the past. Â Cheers, Â Jan Link to post Share on other sites More sharing options...

Indeed, the detents are shallow and there is one special tool that turns it. An example is here.  Your suggestion to use a clean rubber stopper or something similar to turn the button in is very good. I had plain forgotten.

ymc226 Posted April 23, 2012 Author Share #11 Â Posted April 23, 2012 Thanks Jan and Pico. Zhou is branching out from cases to tools I see. Â In a similar vein, several of my filters became stuck on my E39 lenses even though I specifically undertighten them to prevent this. My filter wrenches were too big but I remembered reading that using the underside of a clean and flat rubber soled shoe could work. Â I'll try your technique Jan.

farnz Posted April 23, 2012 Share #12 Â Posted April 23, 2012 A rubber or Latex glove works very well too and you have excellent control of pressure through your fingertips. Â Pete. Link to post Share on other sites More sharing options...
