I've never seen one dirtier!

Well, at least it wasn't leaking oil.

I found the transmission drain hole had stripped threads. I sat down yesterday afternoon and ordered a M10 x 1.5 helicoil set from McMaster Carr and received it this morning!

Les would have set this up on a 5 axis milling machine

but I am just a hack.

It was a bit fiddly to get it properly set up in my drill press but it was successful.

Nice to have the transmission spiffed up and attached. Internals checked over and new seals of course. And new deep spline hub.

Ooh, that looks great Dave. I have to admit that when I rebuilt my T3 Cali I didn't open the gearbox or empty the crankcase. The bike was running well so I just cleaned the cases with phosphoric acid and made that do. Didn't look quite as nice, but it did come up quite well. Heads / barrels etc were vapour blasted.

It looks great the way you did it.

I converted the clutch to a "deep" spline, therefore it made sense to replace the seals and check things out.

It is always great to get the frame off of the floor and onto the bike! AHHH.

Dave Swanson · « **Reply #129 on:** December 22, 2020, 03:03:49 PM »

I had a small setback yesterday. When I installed the triple tree I realized that the steering stop had snapped off of the frame. The stop is not very robust on Tonti frames, at least not those I have experience with.

I swim a mile every morning at 6 a.m. and I find that it is a great time to work through problems of all sorts.

After my swim I had it all sorted out how to properly fix it. Of course, this involved removing the frame I just installed. I ground the remnants of the stop to match up with the stop I machined in my mill and welded it with my cheap MIG welder. It turned out very well! Now I can resume prior programming.

Nice fix ,

Way better than new ...........

Antietam Classic Cycle · « **Reply #131 on:** December 22, 2020, 05:36:27 PM »

I find a broken off, or at the very least bent, stop to be quite common on Tonti Guzzis. That could never happen on a Loop!

Excellent fix!

Nice fix, I have repaired three of them in the same way.

While I wait for a couple parts to be delivered to assemble the front forks I got a couple of pesky jobs out of the way.

I replaced the carrier and swing arm pivot bearings. One of the pivot races was fairly easy to pull and the other took quite a bit more slams with the slide hammer. I also repeated Charlie's method of pushing out the carrier bearing, which is installing a blind bearing puller and pressing it out from the rear as I did on the Lemans.

Since this bike had over 100K miles on it I thought it was prudent to replace them.

I replaced the main seal and input spline on the bevel box.

Ahhh!

Dave Swanson · « **Reply #134 on:** December 31, 2020, 06:01:50 PM »

I shudder to think what I have tied up in this front suspension. $$$

The old forks were shot. So in went - NOS fork legs, new fork tubes, Wirth progressive springs, and new dampers, fork caps, seals etc.

The before and after is pretty dramatic on this one.

I have had this nice set of Konis on the shelf for 20 years waiting for a project. I think these have found a home. I will be deviating from stock!!

I don't believe I have the gumption to restore the originals. After 115 thousand hard miles they have earned their keep.

I envy you guys that have the skill to do this work. Also, it is great to see you all saving these old bikes that would normally just deteriorate away. When i see the rare old guzzi or other 30+ year old bike on the road, running well, looking sharp, thanks to this site, I can now appreciate the time, money and effort that went into making it that way. The rest of us have to make do with newer machines, but the most work I will do is adjusting the valves and changing fluids, filters and plugs. So, we will never know the deep satisfaction you men must feel. Thanks for sharing the process with us.

The Koni or modern equivalent Ikon are a much better shock than stock. Wolfgang Haerter, the Laverda guru takes a new Ikon and machines the old Ceriani shock cast aluminum lower cup with the adjustment arm to fit the bottom of the Ikon, looks stock. I am going to try that with my old worn out stock Eldorado shocks, using the aluminum lower ring on a pair of Hagons.
Bike is looking great!

Groover · « **Reply #143 on:** January 03, 2021, 02:21:33 PM »

I have the same Koni's on my G5, they were also a NOS set that came with my bike as spare parts. I debated the originality as well, and the Koni's won. They look just right on those bikes.

Completely off topic , but , did I see a pan-head with a magneto in one pic and an aftermarket springer in previous pics ? Peter

That is a S&S 93H "Pan" and a W&W springer. A future project. There is also a Baker 6 into 4 transmission.

Thanks for the reply . You've got more projects than I do , and according to my better half "that's a lot " ! Peter

Dave Swanson · « **Reply #147 on:** January 05, 2021, 11:21:50 AM »

A few more bits hung on. Most notably the front fender. Nice!
