Re: What did you do to or for or with your Laverda today?

Took my 1981 180 Series 2 Jota for a ride on the roads of South Taranaki, New Zealand, and then discovered afterwards that the primary chaincase drain bolt had come out and there was oil all over the back tyre!  I thought I could just have a new one machined to fit, but I'm told it isn't a drain bolt at all, but something that works the primary-chain adjuster mechanism!  :o  So now I have my primary-chain whirring about unadjusted (but noiselessly) while the adjuster mechanism is lying quietly in the bottom of the oil-less primary-chaincase! I've been advised to contact closest experts "Redax Laverda" in Brisbane, Queensland, Australia.  Any ideas as to their address/email/ website?

Nothing hanging about in the bottom of the primary case. There's just a slipper tensionner and a hairpin spring which cannot budge whilst assembled.

Adjuster bolt is nothing special, it just has a domed end which locates in a housing in  the slipper tensionner. Nothing specific. And a blocking nut.

Well, it's a little specific. As you say, it has a domed inner end that bears against the tensioner. It's also threaded for its whole length and has no head, just a slotted end so you can turn it with a screwdriver to adjust the primary chain tension. It needs a copper washer, a locking nut, another copper washer and a dome nut to cover the whole lot and contain the oil. You may need an extra copper washer as a spacer depending on how much bolt is left sticking out when the chain is adjusted.

Don't worry Paul, Red will sort your problem in no time. I don't like to publish another member's email address, but you can contact him with a personal message via this forum. Here's his forum profile http://www.laverdaforum.com/forum/index.php?action=profile;u=39.  Just click on "Send PM"

BTW, welcome to the forum!
 
...and the end at which the tensioner sits is hardened.  If a makeshift part is made, be sure to trim away the thread for at least 10mm at the tensioner end, otherwise there is a good chance the case thread will be ruined when the bolt is removed.  The tensioner blade tends to whack around at the tip of the adjuster bolt, a soft bolt will be quickly deformed.

Many thanks for all the help. Red from Redux has been in touch and the bits will soon be coming across the Tasman Sea. Next weekend we'll hopefully be up and running minus an oily rear tyre! Thanks for the warm welcome, Laverdisti!

Bloody good turnout and some very nice bikes too, all but one ridden to the event :D

Coincidentally as shown in this month's calendar:
