The focusing rack of my C330f jammed without any apparent reason.
At first I noticed increased resistance of the focusing knob when moving the rack out from the camera for about an inch.
Then I made several complete movemements of the rack from the rest position to maximum extension and back, the rack looked perfectly aligned and the camera has suffered no hit, but there was a noticeably resistance for the first inch of travel.

Today I tried operating the focusing knob as usual but I noticed a very strong resistance and didnt want to force the movement, the brake focus lever is not engaged.

I am wondering if this has ever happened to someone, I do not know of any Mamiya repairman in my area and I am looking for the C330 repair manual if someone has one to share

thanks

Dismount and re-mount the lens.

IIRC, the lens release mechanism can sometimes interact with the focusing.

At the end the issue was with dirt on the focusing rack.
I unscrewed the six screws that are on the bottom of the camera and removed the bottom plate that allows seeing the focusing rack.
It just needed cleaning and a little lube.
Now the focusing rack moves so smoothly!

glad you solved the problem emmef2. I actually have a copy of the C330f service manual if you or others ever needed me to reference it I'd be happy to.

Open the botom plate, you'll see the rack there n can find what is hanging it up.

edit.. oops, see you already did that. Glad you figured it out.

Hi, I'm new to the forum, also own a Mamiya C220 and a C330f, after the presentation I tell you that I have intended to repair the C330f on my own browsing this forum and I see the friend PeterB has the service manual of this camera, which I do not find her anywhere.
As I do not know which way I PeterB address reopened this post with the intention of bringing you the message if you will kindly have fun by e-mail to my mail.
Again I am new to the forum and am a little lost. If this is not the proper procedure apologize.
Greetings to all.
Ricangel.

Welcome to APUG ricangel.

If you want to contact PeterB (or anyone else here on APUG) just click on their name beside one of their posts.

You should see a number of options come up, including "Send a Private Message" and possibly "Send email".

"Private Messaging" is often referred to as "PM"ing.

Click on the option you want to use, and send your message.

If you are asking for a scan of a manual, it is best to send an email address, because it is difficult to send large attachments using the Private Messaging function.

Good to see the C330 being used, I had one for years, and have always regarded it as an underrated system. Most of my stock sales on tranny film over the years has come from the Mamiya.

Hi ricangel. I am happy to copy some pages for you for "fair use". I originally thought the copy I purchased was legitimate in that that the eBay seller was assigned the rights to copy it or Mamiya had chosen to place it in the public domain but now I'm not so sure. This is why above I wrote I would be happy to reference it.

I'll reply to your PM.

regards
Peter

No problems Ricangel. Did you manage to repair your Mamiya C330 ? What was the problem ?

Someone tampered with the mechanism and mounted it wrong.
