FA77 ltd repair advice

My beloved 77 has, for no apparent reason, gone all loose and won't focus. I assume something has rattled loose inside. The front element has about 5mm free movement in and out.
Did a search here for lens repairers with no joy.
I don't want this gem sent out to just anyone. I'm assuming it's best to send it to Pentax themselves?
Anybody got advice about repairers who really know their stuff, and particularly this lens?
Thanks...

JPSS gets my vote...

I broke my macro in half - repair cost 90

quality of each repair (2 x SDM and 1 broken FA50 mount) has been astounding, lens has come back better each time.

Thanks Peter, I'll give 'em a shout.
Alan Marlow wants 145 for rebuild, plus extra for parts

Might be worth spending a few quid extra on PU Plus membership to get the JPSS discount as well...

I hope there is nothing specific with your lens such that Alan needed to order parts specially from Ricoh/Pentax in Japan to fix your lens, but I thought the break on my D-FA Macro was extreme enough that a repair was uneconomical but I had no hesitation to go direct to JPSS.

Hope it works out for you ok.

Hate to potentially be the barer of bad news - but Alan is often the cheapest

Other than Johnsons and Alan Marlow - the only other 2 I know of would be Harrow Technical and Asahi photo ltd

Just thinking out load...
I'm pretty handy and went to engineering college; how difficult are these things to repair?
The FAs are fairly simple aren't they? If I drop out the front element will I have to re-centre it etc. or will it stay in it's housing and go back in the way it came out?
Can anyone point me at service documents or drawings please?

Ha! as I was fiddling with it, trying to listen for loose screws, it just fell apart in my hand...
Anyone come across this? Ar you any the wiser?

Just a thought - but maybe given that it is sort of an 'external' issue - may be worth sending that image to Alan and asking him if that changes his quote?

That's a good idea Carl, although I think I'll have a go myself. I just need to get some high-quality watch-maker's screwdriver as the things I found in the 'useful drawer' instantly rounded off
JPSS are 150 plus spares also. I feel a new career coming on
BTW, a little screw did fall out

It's probable the front set of elements is held in by a screw or three.
The FA80-320 and FA28-70 worked in a similar way.

Looking at the element structure there should be a group of three elements in that front part.
Hopefully there will be a way to align the focus ring (maybe the loose screw fits on one side of it?)

Could be tricky - and as usual, obvious once worked out!
Just hope you don't damage it

Not the same as the FAs, alas.
