Hi John, thanks for reply and info. Yes that seems right, by positing my query, got me thinking more about what is happening. I now feel inching knob is okay as I turned unit off and came back to it ( did that a few times) and initially fwd projection knob didn't start motor, but if I switched it to rewind, it kicked it as did fwd projection and light and sound. ( just tried it again and sure enough had to put switch to reverse first to get forward to work.
Probably needs a lube? Electronic lube my brother knows a little about it, he has these cans of solvent spray or something, I check with him tomorrow, if either of you guys have any suggestions let me know, and if you think it is more than a lube. Thanks Phil

Hi guys,
Well lubricating seemed to make it worse.
The drive rod if that is right description is moving forward or back depending on which way I turn projection knob, but doesn't want to always kick in, especially forward and also 24fps seems worse that 18fps. There is a belt that is around a cog on the rod to right of frame rate knob, it seems okay. Any ideas on what I could check to se why motor doesn't seem to want to get in even though the rod moves to position. As per orignal post, I can always make it go by pushing in Inching knob and doing like a manual wind up start, but that surley isn't right.
I should add it sounds better running in reverse than forward when it does run. In fact it stopped on fwd projection after a few mins once.
Maybe it is a fault with these as I noticed one on EBay today, one that hadn't been used for ages looking at it, that seller describes similar problem.
TIA
Phil

Hi guys, just an update.
The problem after my investgations seems to be the frame rate selector. If I adjust the FPS, the projector will not project forward, it may fluke revrese projection. And as I have said, the only way to get it going again is to use the Inching Knob, a few turns of it makes motor kick in., I have checked belt and the drive rod especialy where the FPS selector is. The only thing I can notice strange is there appears very little reisistance. There is a White bit of plastic with a screw at the top that moves in and out as you change frame rate speed. Behind it is the fan Is there anything behind this area that I should check, like a spring or something? The other thing I noticed when it is running okay, the Projection selector knob makes a clicking sound as it selects each position, I feel this is right should, but stops doing that when above issue happens. Any other suggstions welcomed. Thanks Phil

Thanks Maurizio for that info, yeah like the Sankyo 600 I have it has something similar too. EDIT
No Sankyo does not have that sorry I read post too quick, 14yo son of mine neded my assistance.)
Maurizo thinking slower about your post now maybe wil help me get this 900 100% right, as even though the screws as I said I believe are now in right spots, when I played back a movie with sound my late father did voice overs on, at 18fps, well as per knob setting saying 18fps light, he still sounded a tiny bit like a chipmunk, I check out now what you said. In case someone played with it to.
Another edit, I see what you mean yellowish white plastic teflon exagonal screw underneath knob cover, can be turned either way,
We learn something new each day. Huh.
Thanks again.
Phil
Edit.
I didn't need it slower, person I got it off Ebay must of done it, I am going to sell this back now I have it working again right. IN fact better.
Cheers
Phil

Hi again Maurizio,
How’s things.
The S905 after some adjustments, has one minor annoyance, its belt is slipping along its drive rod on the cog, only a little but enough to make any speed adjustments I make using the hexagon plastic adjuster underneath the FPS speed knob. I can see it slip each way depending on which way I am running unit. Hence when a voice over comes on, it is a little too fast, and even if I adjust that Hexagon thing, I suspect due to belt slipping, it doesn’t take the change,
You may know Eumig 900 series well 905 910 etc have a belt that has teeth on them, tension seems to be okay. I have tried to wipe of any lubricant or oils off cog etc and inside belt, in case that is problem, no success yet.
Is there any product that can be used? Or suggestions you may have, Just wondering. Ta Phil

Hi Maurizio,
Yes sorry I have confused you by positing that image that was only to show how it should look inside.
The S905 I have I will post some images in this post, I have worked out what is problem, after slowly adjusting that speed adjuster Hexagonal screw and putting it back to how it should be, film now plays back at both 18fps and 24fps, will play back my father's voice overs & Music at right speed he recorded them at 18fps. Even with cover on front, the lights to indicate 18 or 24 are light up right and I can now also feel the tension I reckon it should have when adjustable FPS knob. The Screws for Rods in my view are in right place now.
One problem is still happening and that is putting projector into reverse, As you may know there is a Disc that sits in between the rod or that part the right rod pushes on to make drive road run reverse, It has a Magnetic C Clip attached to it.
Whoever owned this before has broken that or it has come out with wear and tear. I am hoping well my brother is that if he uses the right glue he can attach it back, but if you have a better suggestion please let me know. The two images I have uploaded to post hopefully will show you what I mean,
Thanks again Phil
