Default Genie S60 Platform Rotator Rebuild

The platform rotator on my S60 boomlift quit working a few weeks ago, it was working fine until it was moved to extreme left position, then quit working and was purging oil from lower seal. I have Genie manual, but it just shows how to remove entire unit, no info on the internal workings, or how to rebuild. I was able to order a rebuild kit from Genie using the online service and by entering S# of machine to select proper kit. Calls to Genie have been fruitless, if you are not a dealer they just tell you to contact a dealer. Dealer plays dumb and says he cannot identify what I have by machine S#, I need to remove entire unit and bring it to them, they will rebuild it at an astronomical price.

Pretty sure Genie did not build these, it is someone else part, but neither mfr or dealer will say who built it. I found rebuild manuals from several different mfrs online, but they are all so similar, from an exterior perspective, yet have different disassembly procedures.

So has anyone out there ever rebuilt one of these? Know where Genie sourced them? Have a manual? Words of wisdom?

The part in question is in middle of pic.

So I have had the rebuild kit for this thing for over 30 days, and with no direction on how to take it apart, well, I've been procrastinating....

Nice weather today, and its not going to last much longer, so I decided to try to get it apart. There were 2 allen head screws on top, 4 on bottom, those are now out. In pics 2 and 3 you can see pins in the hole next to the screw, right on the part line between 2 components. I'm pretty sure those need to come out next, I've cleaned edges with a dental pick, jabbed at them with a screwdriver, tickled them with a strong magnet, I see no movement. Manuals for similar type units show these types of pins having an internal thread, 10-32 iirc, but these just have a dimple in center, new pins in rebuild kit have the same dimple. Short of drilling and tapping (maybe just drilling would do it?) , anyone have suggestions on getting those pins out?

I did spot a painted over tag, only info I can get is P#30669, google search for "genie P#30669" took me to same company website that I ordered the parts from. But part# and price are different than what I ordered based on their drop down menu based on M# and S# of my machine, so I'm not sure if I have the right kit

First pic is replacement pin with dimple in one end, it is a steel pin.

Info on other units usually involves unscrewing bottom section with a spanner wrench, but there are no spanner pin holes, just the chamfered screwholes and if you used those you would probably buggar the threads. Looking in parts bag there were also these 2 steel pins and bolts, and it occurred to me that these could be used in the screwholes instead of a spanner wrench, see pics 2 and 3.

I'm completely spitballing this one, maybe those tapered pins and bolts go inside, I just don't know, but the little pins have to come out, somehow

I have looked at the Helac rotary actuators, and the rebuild manuals are in downloadable pdf form, I'll look at a few more tonight, have not found an exact match yet.

On the Helac units, those pins would have an internal thread, screw a bolt in and yank it out. I can not imagine why a mfr would expect the end user to have to drill and tap the pin to get it out.

Edit: Ok, think I found the right one, I'll be damned, they do expect you to drill the pin, then use a bolt extractor to get it out.

Maddening that they cheaped out on those pins. What a pain to drill and tap them.

Just think, some engineer made the decision that the little pins needed a dimple in them so they would be easier to drill, when he could have just spec'd a 1/8" hole

I've been watching this but haven't responded, because my experience was with JLG's. They too cheapened out (their rotator is of a different type) but when I was working for a dealer I got engineering to add three puller bolt holes in theirs.
They said it wasn't necessary as the part was a slip fit, which it was when built, but it was keyed to the shaft and the key would break and jam the two parts together. Once that happened the only hope was three bolts and a puller head to separate.
Those pins look like a "shear fuse" designed to yield and protect the system if it is jammed.
At least you figured out how to get them out.

I don't know if Genie is any better or worse than the other brands, but it seamed JLG used the "come here and hold this while I weld it" school of mfg. None of the pins had puller holes, and the fabricated parts all hand eccentric bushing to make up for holes that weren't reamed, but made before the part was complete.
