I know it takes alot to mash the crush sleeve between the 2 pinion bearings in that gm rear. I would also be concerned about that eaton governor lock. I don't know how a trike handles but, if one wheel comes of the ground around a turn and turns about 10 more times than the one on the ground, it will violently lock into pause traction mode. That is a tuff set up for off-road but, ify on a trike.
You are doing a great job on this build and I am in no way trying to cause you grief or put down what you are doing. I'm just curious about things.
Thanks for the compliment Hydro, and you don't cause me even one iota of grief or seemingly any type of disrespect, my good sir!!
Hey there fellers! I haven't visited the club since Thursday night, because my wife and I drove to N.C. Friday, and headed down to Myrtle Beach yesterday afternoon, with our son, daughter-in-law and the two grandyoungins. Beautiful weather!!!!
anyhoo.....
I was pleased to find the anticipated continuing interest to follow the Threedom build, i.e., Fred Camper and many other fellows urging me on as well, hasn't waned.
I can't wait to get back to it next week, as long as my very sore and multi-discolored right shoulder doesn't hinder me TOO much. nahhhhh! It's just going to be a long time healing the sprain and bruising the orthopedic doctor diagnosed last Tuesday.
Yep, Hydrocarbon Rocket, the choice to use the Eaton Locker axle was more than a little thought provoking, but as you'll have read earlier on, either I decided to buy this one, or most likely, return to a zero state of progress, again. YouTube provided a whole truckload of videos of operation and design information. Interesting too!!
But, I don't foresee to lift a wheel, causing a 100rpm difference in wheel differential speeds, and subsequently locking the diff is in the cards for this trike. Improbable, but I'll grant you, not entirely impossible. The only axle I'd ever lifted was the inside wheel in a left hand turn, with completely too much zeal, on my '53 Servi-car when I was 22.
The beloved late CB900C trike never broke traction. well almost when I'd dumped the clutch at 8,000 rpm, and left 2 ghostlike 265/50x15 burnout witness marks on the pavement! And taking into consideration the GL1000 Threedom set-up is SO much heavier than the CB900C was, I'll NOT be doing something that bizarre, again. Plus, I have a great deal of respect for this 37 years old masterpiece of Honda engineering, and promise y'all not to be reckless with it!
Yes, HCRocket, the 2 opposing GM pinion bearings do have to be loaded against the crush sleeve, just as you'd noted, but I hadn't given any insight into how that was accomplished, yet. If you're familiar with the GM 8.5 10 bolt differential housing and internals, and I believe you and many other astute, and wise beyond compare, NGW members are, I'll have to get a few more photos together to detail how the, "Companion flange", ( that's what GM Parts nomenclature identified it as) was altered, to end load the 2 GM pinion bearings, AND still provide the surface for the OEM GM pinion shaft oilseal, slightly modified too, to seal against. Smoke and mirrors?
gotta go now! Ill update you fine fellows, and some womenfolks<TOO, in another week-- When we get back home
ciao for now!

O.K., here I am again, at home with my computer and photo files to continue the "build".
previously, We'd left off where HC Rocket had inquired about my method to capture the 2 pinion bearings, which are positioned either side of the GM crush spacer in the GM differential punkin.
In order to do that, I had to massage the GM," Companion Flange."
Yes, the GM pinion shaft threads that capture the Companion Flange were modified, but not cut off completely. The GM pinion threads' outside diameter, and overall threaded length were both reduced. The Honda pinion shaft stub was end drilled and tapped, to match the altered GM pinion shaft's turned and re-threaded stub dimensions. That's all I'm giving away ........ Both assembled shafts' mating edges, having been equally chamfered prior to welding, can be observed in this photo.
