light repair help (lens lock mechanism)

Really sad that I'm in search for help on a technical issue on my 503CW

Apparently the mechanism that locks the lens on the body is malfunctioning, the button is stuck (not coming back by itself) maybe the spring is broken but I think is more likely to be stuck as sometimes works, but lately is completely stuck and Im forced to use a pin or hook to make it come out again,

I think the problem came because of very bad humidity and the lack of use (1-2 months)

Please see photos of the release button that is stuck and the little lock that I have to force with a small pin in order for the button to come OUT again..

My question or the advice I need is, shall I try using some kind of lubrication to see if the problem goes away? I'm thinking 3in1 Oil? or WD-40?

Thanks a lot for your help!

Carlos

1. do not mess with lubrication, that will most likely not work and typically makes a mess of the camera inside. Behind the lens release button is a Teflon bushing, that is unlikely to get stuck, Teflon being Teflon.

2. best thing would be to have a trained technician look at it of course.

All that said:
I obviously do not know how confident you are in opening the camera yourself, but you might want to have a look at this webpage. One of the pictures clearly shows the white Teflon bushing.

But again: only if you feel confident, I would recommend a trained technician in 99 out of 100 cases!

Interesting excercise. I enjoyed watching your pictures and description of the process. I've heard that its more difficult to this operaion with a 2000 camera. Do you know if this is true?

2000 series cameras are real horrors to work on.
Only those who were fortunate to receive a 4 day training in Gothenburg some 35 years ago stand a chance to succesfully cary out repairs.
That includes the first step the removal of the outer shell from the camera mechanism.

As far as I know there is no independent repairman able to service these complicated bodies.
The same goes for the successor of the 2000 series: the 200 series.

A 2000 is an entirely different camera, the FP shutter makes it much, much more complicated.
 
thread update

I managed to fix the problem by using a bit of WD-40 formula...

Seems to work just fine!
 
My lens button is stuck IN as well- camera works fine but afraid to use my heavy 40mm CF lens because it won't lock onto body.....how do i get this button unstuck- I can't see the second picture clearly???...Can anyone help?
 
The second picture shows the latch mechanism that engages on the bayonet. The part that is sticking could be the button in the body casing or it could be the locking lever. A very small amount of lubricant is not likely to do any harm and may free things up, the trick is getting it to the right place. If things don't work out please contact Classic V or speak to Hasselblad UK. It is not likely to be serious or expensive.
 
First take the lens off,

Now with a thin wire, make a small hook so you can grab and pull out the little latch that is stuck, once you do this put the lens back on, it will get stuck again, take the lens off and pull the latch once more, do this as many times as you feel, then, when you think the latch its starting to loose up, put a little bit of lubricant (I used WD-40) and keep playing with it....

Almost two years after I fixed this the camera is still working fine.... the only thing I have noticed every now and then is some kind of oily (WD-40) smell coming from within the body, but appart from that no functional or image quality issues at all...
