Olive Drab would stand to reason it has the older tooth style clutch cam. In some clutches being tight and some not, believe that’s a
rivet concept, should only take a hammer,
drift pin and anvil to tighten them up, or re-riveting or bolting. Been a while since I tinkered with them but it’s possible to either pound something tight again or re-rivet. Do such things often with
PAR cans.
Sorry, memory in this assembly is not serving so well at the moment, I don’t have any Lekos in for upgrade to the theater in the garage at the moment and all manuals showing this parts assembly as with bone yard fixtures are at work and boxed up for a later day. Been a little while since I saw a loose tooth
grip, my guess however given your description is that one side of the cast wings that is on the
yoke and holds it to the
yoke has broken off. Really common problem. Just need to replace that part - this the reason that 20 years after where I work stopped using that series of
fixture, I still have that box of that part for replacement parts. Could very likely be that one or both of the wings on the
yoke mounted part has in it’s ability to hold onto the
yoke broken loose. This would explain the certain slippage and
play in grabbing. That clutch cam grabs, it’s just that the
yoke is no longer affixed to the clutch cam.
Hinge holes, are you talking clutch cams or top and bottom of the
pineapple hinges? Yep often
fixture to
fixture once one gets into swapping top and bottom sections of different lot numbers they don’t
line up. Also if memory serves, that hinge is more an oval slot between a threaded rod and two acorn nuts. 6-32 by memory in size. If the nuts are too tight, it will pivot instead of do this and swivel while doing so. Makes for a hard fit as with in general the retaining
thumb screw at times not
lining up
fixture to
fixture.
If you have to in this case remove the hinge pivot to align it in
fitting, my first concept would be the hinge nuts too tight. After that, who knows, could be out of alignment by way of a warp or perhaps a lot number thing with the overall dia. not compensating for the pivot. Such a thing I would study for a while on my work table but after study by you or me would clearly show what’s going on with a little study. Should hopefully be a easy fix.
Allen type bolts would be
socket head round head or cap screws by definition in this area. That’s as far as I know a un-stock part and something the end user added. Should work fine as long as it is loose enough for the oval hole to function. Washers are also not standard, the
stock acorn
nut has a washer part to it’s top. Should the washer be too large, this could also prevent that
play to the pivoting within the oval necessary to function. Possible that it’s the washers, try without as washers I have not seen before in this area.
On so many projects, soo little time, welcome to my world. I’m on about at least a five year backlog at this
point for many things but still intend to get to all. The above box of
Altman’s is my carrot on a stick for the day I finally get caught up. Oh’ to just sit down an tinker with rusted solid and trashed
360Q’s... Not going to happen in the near future but it’s my goal and ain’t nobody going to touch my lights until I have a chance to tinker with making them right.
Hopefully with time in taking out of service what is not factory spec. you will have time in keeping them as your carrot on the end of a stick, project to get to in working hard on often less interesting things. Until than, box them up and don’t let anyone touch them. A spraying of WD-40 all about them also helps while in save for a later day mode.
On trip to the powder coater, not sure if I would do it beyond origional color concept. Often flaking and or surface rust develops under the heavy coat of paint. A trip to the sand blaster at least first might be necessary - this given a reproduction of the original paint color.
Ah’ the joy in tinkering with fixtures and solving problems. Look at it this way, had our careers only been to do what we love, the world would be all easy - too easy thus boring. Instead, in addition to stuff we love, we get stupid stuff thrown in to mix it up. Thus the concept of my carrot on a stick. Gonna get to it... eventually, but until than it’s inspiration to get the day to day stuff done in some day realizing that concept.
