I finally got round to investigating the floppy brake lever on my T3 Cali. Took the lever off. It has a recess on each side of the pivot hole as if it should should perhaps have a light spring washer or something in there just to stop it rattling. Can someone more knowledgeable advise me on this please? Thanks in advance.

Does this sound familiar - does the lever pivot hole also have a round metal bush in it? On the ones I've had, there was indeed a wavy spring washer that goes on top of that bush before the lever is put in (stick in it place with a dab of grease). THEN when you screw the screw in, you can adjust the amount of free play (floppiness) by tightening the screw to compress the spring, when you've got it how you want it, nip up the locknut underneath. (Note you can also do it too tight so lever is binding.) I'm assuming the top hole of the lever mount is the O/D of the Allen screw head, and the bottom hole is M6 threaded. |

Mike H has the lever minutiae just right, the spring is the "thackeray" type, often used underneath the steering friction knobs of old. As hard to find as the microscopic allen grub screw...

Mike, you described my set up exactly and answered the question. 'thin wavy washer' was what I was trying to describe. Ken, I don't have a grub screw. Maybe that is a later Mod by the factory? Is there a generic supply of these washers does anyone know? Thanks for your answers. PS: should the bottom of the mounting be threaded? if so, mine's stripped.

Ken, I just read you post on the v5 seat thread and see your bike is a '75, so perhaps they simplified the system after your model, mine is '77

Very small one, same OD as the screw head, you wouldn't be the only one looking for one: https://www.laverdaforum.com/forum/index.php/topic,95115.0.html

With regard to the various 'spring washers', 'toothed washers' 'wavy washers' etc (not to mention bushes, context specific tabbed washers, slotted bolts, etc) used in various locations on your Guzzi, and which will invariably have gone AWOL over the years and been replaced with "that'll do" from the spares tin, I found a copy of the parts diags to be extremely helpful, and then (in my case) a peruse of the photos of those parts on the Gutsibits site.
So for the parts, an example: https://www.gutsibits.co.uk/pr/TheShop/index.php?q=gear+lever&f=d&Model=6&search=SEARCH (check out, particularly SSA98660 for the 'slotted bolt', and the wavy washer employed there). And for the parts diags, I absolutely recommend that you go here (https://www.tlm.nl/en/parts/new-parts/partsmanuals/) and then download a copy of 850 T3.pdf from the list of parts manuals. The 850T3 one is, in particularly, exquisitely and precisely hand drawn, so not only can you find the part numbers, but you can actually _see_ what parts were fitted, where, and in what order.

Ah bugger. You mean the 'front brake' handlebar lever, don't you?

Being a bit of a tart, I like my bikes to be as original as possible, but am not averse to making it more pleasurable to ride at the expense of originality.
My recently acquired 1000SP has an ’orrible clutch lever which will have to go before it goes on the road. The levers and switch gear on one of my bikes are, to me, perfection, and while the levers are easily dealt with, I’m not sure if I relish faffing with the electrics. |

Whilst I agree with Barry in every particular I would just express a note of caution.All of the original parts books for the Loop frame models show the sump pan back to front.The drain plug is shown at the front when in reality it is at the rear.This is the only mistake I've noticed but I don't have a Tonti so can't comment on the accuracy of those drawings.
And for the parts diags, I absolutely recommend that you go here (https://www.tlm.nl/en/parts/new-parts/partsmanuals/)</span><span ="reducaseing"=""> and then download a copy of 850 T3.pdf from the list of parts manuals. The 850T3 one is, in particularly, exquisitely and precisely hand drawn, so not only can you find the part numbers, but you can actually _see_ what parts were fitted, where, and in what order. </span> [/QUOTE] |

I think (some of us) may be at cross-purposes here, Ken. So before you head out into the cold...
I _think_ the OP *may* be talking about vertical play in the front brake lever, where it sits in the pivot. Not play in the direction of operation (i.e. squeeze to operate!). |

Yes. I now understand what you were talking about Ken. Barry, I got quite excited for a while at your Gutsibits washer. But thanks for the parts book link, very helpful. |
