Hi Everyone
This is my 1st Post but I've been reading & viewing this Wonderful Pentax Forum for sometime . . . My Pentax Cameras include a K10D, K5iis & Q7 . . . Lots of Fun !
I very recently purchased an Older SMC Pentax 6x7 500mm f:5.6 Lens and it was operational for about 3-weeks BEFORE an internal Stop / Glide Bracket came loose & allowed the Lens to Twist Apart into it's (2) Main Assemblies . . .
Here's some Photos that Show What's Going On and & I've Managed to Acquire (2) Replace Screws ( That were Missing ) so it Doesn't look like I need any parts . . . All is Well NOW, I just have to Learn How to Put it Back Together !
The MAIN THING I NEED HELP WITH is . . . I'm Not Sure of the Correct Sequence of Dis-Assembly & Re-Assembly . . .
The Lens was Not Designed to Be Able to Completely Un-Screw when Trying to Focus the Lens ( The Stop / Glide Brackets NORMALLY Stop that from Happening ) I Spotted & Fixed the Problem ( 2 ) Missing Bracket
Holding Screws
I haven't been able to locate any Service Manuals or ANY Specific Information on the Sequence of Assembly or If any Unusual Tools are Required . . . Any Help will be Greatly Appreciated !
Just would like a Little Experienced Guidance on how to safely proceed . . . I really like this Old SMC Pentax 6x7 500mm f:5.6 Lens & want to get it Back in the Game !
Many Thanks & Cheers from Orion12
