Hasselblad 500CM Rapid-winding crank doesn't stay in place

[masterjbates]

Hi everyone, I recently acquired a Hasselblad 500CM several weeks ago. The seller had this camera CLA'd and included the receipt to show what work was done, It indicates it was cleaned, lubricated and adjusted to factory specs and the following parts were replaced (Upper plate foam, front plate foam. release button spring and governor).

When I received the camera it seemed to function perfectly. I put a couple of rolls of film through it; however, I now seem to have an issue with the rapid-winding crank not staying in place.

As show on the below image, it wants to rotate back to the red circle. I have to physically hold it in place at the solid red dot in order to fire the camera. After winding the crank, I'm able to wind it all the way around but again wants to fall back to the red circle as shown in the below image.

At first it would stay in place at the red dot once in a while; however, now I always have to hold it in place to be able to keep it at the solid red dot.

I'm guessing this is probably not a DIY fix? Has anyone encountered this issue? Does anyone know what the cause is and what it involves to remedy?

I wasn't able to attach a video but I did include the below link of a video I added to youtube.

Any help or suggestions is greatly appreciated.

Thank you

I can't tell for sure, but your wind crank appears to be missing the spring-loaded part which locks the crank into place.

It would save you time, effort and money to take it to a Hasselblad repair man so that you can start enjoying the camera.

Buy a replacement, if you are in able to repair this yourself, as I speculate the labor charge would be greater than the cost to replace that missing part

Keep the one you have now, and, if you've the mind to, with the proper sized screwdriver, practice disassembly and reassembly so you know how to take care of it, with the parts you already have; an afternoon's pursuit, at best.

There is a spring loaded pin that is designed to lock into a spot on the camera body. I suspect either there is a problem with that pin; a problem with the fitting on the camera; or it isn’t being installed correctly.
These photos show the little tab you compress to unlock the crank, and the corresponding pin it retracts when you move it.
If this had a professional service just before you bought it, have you contacted the company that performed the service? They should stand behind it-if this isn’t user error.
