there is still 5th screw in up position, as seen in circle (1) in picture below. loose it then you can take lens off body.

pay attention to (2), this is pole to pass distance information to rangefinder. do not drop it.
(3) is the metering needle, do not hurt it.

as i said in first post, my 35RD is acctually not shutter gummed problem. I opened front lens elements just to clean up the lens. I have to go further to fix the slow speed problem.

you need to remove upper cover and bottom cover if you want to deassemble the lens from body. for bottom, it is straight-forward. to remove up cover, unscrew winder and re-winder first, after that, you need to unscrew the self-timer lever. this is a little tricky, as it is un-usually clock-wise.

now you reach the blades. the front one is aparture blades. shutter blades is behind it.

use cotton stick and Zippo fluid to clean the shuter blades. this would fix the shutter stick problem effectively.

now you can do something to front elements. there are 2 notches on its side, see (2), for you to rotate (counter-clockwise) front elements off.

you may need apply big force to loosen that.

(1) is a gear of adjusting shutter speed. you'd better remember its position and keep it unchanged when re-assemble.

unscrew 3 screws,(already removed in last picture, see the 3 holes), you can remove this ring, which adjusts shutter speed.

attention paid to the red circle area, there is a small ball under that, for speed ring step postioning. do not lose it.

openning the front element of lens
--------------------------------------

it is very common for these old rangefinder cameras to experience a "shutter stick"  problem if they were left unused for many years. an easy way to fix this problem is to use Zippo fluid to clean the shutter blades. to reach the shutter blades, you need to open the lens elements first.

use tweezers to open the "pressing ring" in lens tube. then you can easily remove a plastic plate togather with metering cell. I am not native english speaker so the picture below will tell better how to start the 1st step of the task.

曾经在一个国外论坛上交流过35RD的拆修,后来隔上三五个月就有老外发email询问。那个论坛上不了图,就上在这里给他们一个连接罢了。。。说到这里,建议无忌开一个英文论坛,也许会有些新血液。。

OK, now a few pictures for disassambling Olympus 35RD.

[2005-03-17 23:50 补充如下]

a few words about the 35RD camera in the pictures:

I bought this 35RD from ebay, at about USD80 including international shipping. unfortunately its slow speed as 1/2, 1/4, 1/8, the shutter will stay open after release button pressed. It can be reset in half way of next winding. this problem will not happen to higher speed or B.
I thought it to be a "shutter stick" problem, which I experinced a few cases on other similiar cameras. that need remove front lens elements and clean shutter blades.
but this time it did not solve the problem. in "The Classic Camera Repair Forum" Winfried suggested that it is escape gear problem and told me I need to disassemble the whole lens assambly from camera body. I followed his suggestion and successfully restored the 35RD.
but this 35RD still have some other impefect: scratches on its rear elements, not smooth speed ring. so I sold it at about USD60 after getting another 35RD in excellent condition.

for those new to this forum, pls note that the replied posts in this thread is of reverse order, eg, first post in bottom. you need go to last page for strat.
