Automatic registration

I would miss you guys

Stay together, except for the transmission the bikes are the same.

Don't build the wall !

we have problems doing basic moderator stuff right now, how the heck do you think we are going to add a subforum? the auto guys need to stay anyway, weird as you are.

Weird is the word But you just gotta love them.

I love this site & the high brow sense of humor.

Weird just weird ... But that's why I have Husky's . I like having something that the majority don't...
Maybe I need a weird auto too??

yeah, go on, tip out the bank account and the super and get an auto.....Im on it

I've read the parts lists about autos.
The drums are screwed on gear on 360-76, 360-77, 430-86+.
The 390 and 420 drums seems to be machined with the gear.
It appears to be the same on 500 ae but exist with a drum screwed on gear.

I have on my 420 a 430 drum welded on the gear with also 430 shoes ( see pics)



Is there others riders who have the same device ?
It would be a good idea if we could made new drums which
could be used on all autos and new shoes.

Is the 360 drum the same that 430 ?

360 drum:

The 360 and 390's use a helical cut gear behind the drum. All the others use a straight cut gear. Not too difficult to mix and match though. I have a 420 drum to experiment with when I can find the time. Just need to see if the straight cut gears are the same diameter and ratio as the helical ones.

I have a 420 engine with the steel shoes and 430/500 drum, always assumed it was a retro fit but maybe it was a use up the parts or a development thing?
Straight cut gears use a different gearbox main shaft in the 420 due to different drive selection.

Can't remember if the small gear on the main shaft is part of the shaft or pressed on afterwards !

Drums are easy to make. I have had some made. Machine from solid - not pressed as original. Mild steel works fine or a low alloy engineering steel. Didn't bother with expensive heat treatment processes as don't use the bike enough to worry about it. Several seasons of gentlemen VMX racing and no discernible wear.

How much did you pay for making drums ?
I count for you 1 x 500 ae 84 and 1 x 390 amx 78 or 79 in your garage ?

:-) It was more of a wish, a 'nice to have' request. I know how tough it is to provide a free online community run by volunteers. I certainly appreciate CH and the volunteers who run it.

As for us Auto guys, we just like riding these strange bikes that were designed and built by a small company of dedicated engineers who believed in Autos so much they risked the company to make them. It really was one of the top engineering achievements in enduro motorcycle design. The Auto story is a big part of what makes Husqvarnas so cool.

Well said, my thoughts were just to bring the Auto transmission related stuff together. I guess there is the search function, which will do the same job.

Sorry if I ruffled any feathers.

Paul.

Part of the main shaft I'm pretty sure, I have swapped several shafts and wouldn't go the long way if I could go the short way!!

Can't recall for sure but it was a batch of 2 and cost me about $400 for both. Done on a normal lathe so I guess a bigger batch on a CNC machine would be cheaper. You have my autos correct - it's a 78 390.

For the 430 I presume?
