What are these tools?

[Groover]

Found these in a box that came with my G5. What are these used for? Might give me some insight on what may have been done to the bike by the previous owner.

Left one looks to be a rear shock adjustment tool and the other one looks to be some type of socket for some  type special nut to adjust something, possibly a shock also since they were together????

The left one is called a pin spanner. As mentioned, it might have been a shock tool. I can't think of a use for it on a Guzzi. A hook spanner yes, not a pin. Unless the tool on the right was turned with the spanner??

One on the left is what I'd know as a C spanner or wrench, used for either rear shock spring adjustment or fork adjustment depending on the type of forks installed

The one on the right is called a few things I've heard pin socket and beer nut tool. It's used for either removing the clutchshaft retaining nut, on the clutch hub at the front of the gearbox, or it may be for the crank nut sprocket inside of the timing chest, depending on the size. I cannot remember if these special nuts for the clutchshaft and crank sprocket are different sizes or not

I think the second pic by LesP is the Layshaft nut on the gbx endcase, AFAIK that uses a normal hex nut but it's thin and ideally needs a long reach hex socket with the outside edges turned down a little, so not applicable.

Then again I'm not familair with the finer points of the G5

[Groover]

Ok, thank you. So if the tool to the right is for that what LesP showes, what would have been the repair done? (best guess)

[Old Jock]

Les P's first picture is correct showing the clutch hub, that nut needs to be removed to either replace the clutch hub or to remove the clutchshaft from the gearbox case.

So if you're asking me to best guess why the PO included the tool , or purchased it in the first place. If it's the correct size for the Clutch hub, likely scenarios IMHO are

To replace the clutch hub, or to replace the gearbox input seal (most likely the gbx input seal, best guess)

As part of a gearbox strip, could be to replace bearings or seals, or O rings anywhere in the box

If it's the correct size for the crankshaft sprocket in the timing chest

Chain replacement, sprocket replacement or digging further into the engine eg: front mains replacement, I would think these unlikely unless the bike had a really high mileage.

There could be a myriad of other reasons but I reckon these are the most common

[Groover]

Great reply Old Jock, thanks you very much!

It’s possible the pin spanner fits the steering head bearing nut. It’s only a possibility because I’ve not found one that works as well as a punch and hammer unless you take the tank off to get the room needed. Then it has to be thin enough to fit in there. Otherwise rear shock preload is the only other place I can imagine it being used on a Guzzi.

[LesP]

Try the C spanner in one of the holes in the tool body.

[TOMB]

The wrench is /can be used to tighten the screw in  exhaust clamps on  Ambo, Eldo, V7Sport, and possible used for certain models of shocks,

The wrench is/can also used to remove/tighten Chucks on lathes.

The socket type with the prongs is used for tightening the nut on the input after the clutch hub is installed

Either that was brilliant or I’m more loaded than I thought..

Not trying to argue... But.....

Pin spanners are used where there is a hole to put the pin in. Hook spanners are for grabbing an edge in a slot as in a loop exhaust nut.

Hook spanner for exhaust nuts on a loop. Hook spanner for steering head nuts on a loop, at least.

Pin spanner works on some shocks. But....Normally a hook spanner.

Yes a pin spanner of some size or adjustable will work on at least some lathes and probably other tools that have a hole to adjust/tighten something.

I did a quick search for the socket style pin tool. I couldn't find a proper name for it. Does someone know the proper name for a pin style socket?????? The name for the internal pin as well as the one with the pins on the end?????

Without the two tools pictured in my hands, and looking at the holes on the sides of the socket, I would guess the spanner fits the socket??

JMHO,

The pin socket used to tighten the input shaft hub nut... it is of the "poorboy" variety.  It cannot / should not be used with an impact driver.  The better design, and I think Others, here will agree - is the one that (is it?) Rolf Halvorsen in Norway makes.  See the two graphics... poor quality as the graphics are.  Note also that Rolf's alternator removal screw tool is one that I would prefer, compared to the hardened steel rod. Rolf's tool is suitably hard, too, which is critical... but his tool absolutely will not get cocked-in-place which is my worry re the hardened steel pin urged-on by the OEM alternator bolt.

This Old Tractor - has a document, attached (if I can manage to do so), that is excellent re bigblock tools.  Not only that, there is some good advice re service matters.

Thank you Greg Bender!
