Anti Back Lash Gear ( Transmission )

[HV]

Here's another feature: In a trans-mission, you can get sound at a stop when it's hot due to freewheeling gears and lash. We addressed that by adding an anti-backlash transmission gear. Now there's another piece making the bike quiet.

Gee... they pat themselves on the back for reducing the number of parts in the engine...then add some to the transmission!

Wonder if that will stop the KLANK into first?

I think it's more for neutral rattle.

I'm wondering how that's connected to the valve train?

Now there's a clever bandaid if I ever saw one. Not sure about long term life of the teeth? I think between the two, the rattle might be more desirable.

This exact design was used in the gear box on Saab two stroke cars in the 50s and 60s.
A lot can be said about the reliabillity of those, but the scissor gear did work.

I've seen them on camshaft gears before for the same reason, to stop over lobe center chatter. Fairly common adaptation actually. I guess as long as heat treatment is ok and load carrying not compromised it should be fine. This gear looks thin to me, that's all but again, spring rates are unknown so that would determine wear amounts.

I guess Andrews will have to get back in the transmission gear business....   

[BUBBIE]

 

Didn't some use Sawdust in the old days (added to the Gear oil).... Especially when selling their Noisy what-evers?

Now, Don't get the Idea I tried that... But it Does work... Hard wood small chips worked the best and lasted a little longer in a Rear-end...

Kinda why I use Shockproof today... Every Little Bit helps...

Sounds like they put massive R&D into quieting all unneeded noises so they could keep the exhaust at a decent level.  So less valvetrain noise, less transmission rattles, every little bit helps.

The primary drive was a spring-loaded split gear on my '83 V45 Honda.  Didn't have the InterWeb yet, but never heard of any problems with it.

Mitsubishi used the same idea on the input shaft. We tried it at Ford but the bean counters stopped it.

Ron,  Do you know if this " Scissor Gear " will drop right in the '16 and prior trans and wondering if it would make a difference?  Was at HD Sat. had my parts guy look up the gear for the '17  it's $59.35. It's 1st gear  price is right, just wondering what else if anything they did in the'17's and would it make a difference in the rattle in '16 and prior? 

Thinking a little winter garage therapy, just for chits and grins to see.. Greg

Mercedes uses these scissor gears in its recent engines (camshaft drive).
