• Ciao Guest, The owner of this website and GTMotoCycles.com lost his home completely on the morning of January 8th in the L.A. Wildfire Storm. Most of his neighborhood is gone, and a few friends were killed along with their pets. The GTM SHOP and STORE are functioning normally, but we DEMAND EXTREME PATIENCE on orders as we are a SMALL business and Todd usually has his hands on nearly every order before it goes out. You can find more info on a post named L.A. Wildfires in the USA section. Our heart and best go out to everyone in this horrific disaster.

I need to check the clutch rod length. It seems that the tool for checking the length would be pretty easy to make. Can someone supply me with the length of the rod in the tool?
Thanks, Jon

Just take it out & measure rod, You can not buy one, none in stock & part has been discontinued. You would have to make one or use a used one the same size or longer.
 
With out the tool, how do you know how long it should be?

Time to put on your thinking cap. With the gearbox mounted to the engine, place a long rod into the channel and mark where it is flush with the end of the gearbox. That is measurement 1. Next measure the thickness of all components that push the pushrod. That is measurement 2. Getting the thickness of the portion of the piece that goes over the pushrod can be done using a vernier caliper. Subtract measurement 2 from measurement 1. Then I'd take a couple mm from that to give the length of the needed pushrod. If this logic doesn't work, please let us know.
 
From what I and other Techs around the world have found from changing the 8V clutches & 2V CARC clutches is that you never need one. I used the tool on my 1st three, None needed. This is why you will not find any for sale and they discontinued the part numbers.
No one ever ordered any, ever. I've changed around 7 8V clutches and all been good.
I do believe Guzzi was worried about quality control on the thickness of parts assembled, rod wear and such.
If you need to measure yours do as John says or you could seek out a Guzzi dealer that has the tool & buy it from them.
There are no rods for sale at any importer in the world, I have checked.
 
Thanks John, that does make sense.
The reason I am even contemplating this is that over the last few thousand miles I have had some clutch slip on really hard acceleration. I changed the clutch on a road trip in 2023 a thousand miles from home. It was updated with the 1400 unit and my current logic is that the rod would likely need adjustment with that change. The clutch now has about 35,000 miles on it.
 
Once a clutch slips it is next to impossible to stop slippage. May be necessary to replace the clutch again. Then check rod length. if available the 1400 clutch rod may be the answer. In any case, slippage may be from the rod being too long. It is easier to shorten a rod than make it longer.
