K-70 exploded view

Just in case you are curious to see how the K-70 looks inside.
I made the solenoide replacement, and the camera is up and running again.
it's actually not that hard when you just follow photogem's tutorial here

As an old bench tech thatís a great shot. What surprises me about the solenoid is how similar it is to the Canon AE1 release magnet assembly MG2.That was the most common AE1 failure, and a simple repair.



Hang up and DRIVE!

This vintage solenoid looks very similar to the one used in the early Pentax Program-Super:

Double for me. I've fixed a lens or two, but any cameras I've disassembled were junkers that never going to be put back together again.

Looks there's a lot more slack to the solenoid wires than in the K30 which should make the repair even easier

Cheers, Gerard

Not really, to the left one has the same distance but to the right there is more space.
I never found it difficult on the K30/50.

The front cover is fixed that bit more tight to the back and needs a bit more grip to losen it. Same with the K-S2.

Otherwise it is pretty straight forward.
