service-repair manual for Mamiya 645 Pro

From: Armando on 11 Nov 2009 05:23 Hi, I need to change the bayonet on my 645 Pro TL camera. A repair manual could be useful to know how to open the camera body. I didn't find it by Google... Any help is appreciated Thank You Armando

I think I won't make any change on my camera. The reason why I bought the bayonet is a little "play" of some heavy lenses I had noticed. I use the camera for astroimaging and during long exposures the rotation of the camera (to have no stars motion on the frame) together with the weight of the lens could cause a little shift of the lens... But I need to be sure this problem occurs since I have to make some pressure to be able to manually "shift" the lens attached to the bayonet. Thank You again Armando
