Quota ran 220 miles without oil in the pont.

Looking in the shed for something else entirely I found all my bevelbox shims today! I thought I’d given them away.

If you understand how to set up bevel gears it isn’t terribly difficult, although it can be time consuming. It isn’t something most novices would undertake, at least without close supervision by someone experienced because the results of getting it wrong tend to be very expensive.

I have shimmed electrical submersible pumps before. The principle is the same.

My immediate concern is to get that pinion out, so I can assess its status.

Once I have some factual parameters, I will be in a better position to decide what to do. The safe way, would be to replace the final drive.

I found new ones in Europe, for 1500 EUR, plus shipping and whatever US import tax of the day.

Harper has new 8/33 pinion and ring gear in stock; I want to retain the 7/33 ratio.

eBay has one final drive on sale, for 200 USD. No history available.

[pete roper]

I thought the Quota used the 8/33? No matter. I’d certainly opt for the lower gear option.

With regard to buying *New* the factory hasn’t made 7/33 gear sets for donkey’s years. I’d be surprised if even 8/33 sets were available ex-factory now. Most of the stuff available nowadays relating to gearboxes, final drives, clutches etc. is aftermarket. Some of it is fine, although how long this will remain the case remains to be seen. Most gear-like stuff though is generally contracted by Stucchi I believe. It may be sold through other vendors but I think they are the player in the older parts game and, once again in my experience, their quality can be less than stellar! This isn’t always the case so I suppose it depends on who bids for the work and whether they are credible. Fact remains I’ve built some pretty shoddy gears into boxes for people and have always told them this exactly. Sadly, if you go the rebuild route, these potentially wonky gears are your only option.

The videos you linked show how the pinion carrier is a sliding fit in the box. If you’re afraid you might damage the casing by biffing the carrier flange and it’s tight? Just stick a lord of heat into it with a blowtorch! You aren’t going to be re-using anything that’s inside the box in terms of bearings or gears.

You are correct. The Quota stock ratio is 8/33;

Harper has the gear set in stock for 670 USD.

Throw in seals, bearings, gaskets and shims and you’ll be looking at close to a grand. Far easier to just find a decent second hand bevelbox.

Cheaper and more convenient, I agree. Easier? so far, I only found the one on eBay, which bevelled box looks terrible.

May be worth inquiring on the Quota Facebook page or on Wildguzzi or MGNOC if anyone has a spare one lying around.  Some quota owners have multiple quotas, it wouldn't surprise me if they have stockpiled some parts as well.

I think I suggested Guzzi Classics in Long Beach before, try him. He’s not good on emails but will respond to a phone call. Then there’s Harper’s. They too respond better to a call.

Here are a few.

Bevelboxes.

Errr, Pete, that link takes me to somewhere on the TLM site, and no bevel boxes to be seen. I have the impression, that is not what you intended.

Works for me:

[pete roper]

It worked for me as well. The link above works for me as well.

If considering a second hand box make sure there is a clear pic of the pinion teeth. That tells the story.

Or just go to the TLM site and punch in ‘Used Cardan’

Hmm, there's some weird bollocks happening there. I land on a page with no info, and the "why TLM" text. Possibly because "the internet" sees that I am in a non-english speaking country, but who knows.

Whatever, if it works for the rest of the users here, don't mind me. I don't need a new bevel box. At the moment. I think.

[Tomchri]

Works here.

Cheers Tom.

Thanks...

They all look aesthetically beat up, and more expensive, by far, than the one I found on eBay for $200.

Quick calculation, the best looking one is 425 EUR minus VAT 21%, you add the cost of shipping, the import tax, now than the below $800 exemption has been revoked.

Tomorrow, I will take the drive out, try one more time to remove the pinion carrier, and head out to MPH; Mike never responded to my email about the loss of my drain plug.

MPH have a lot of Guzzi spares from their dealership days.

Here's my bevelled box; you can understand why I am not so eager to replace with a rough looking one.

I am going to fix this one. Replacing the gear ring and pinion set.

I tried again to remove the pinion carrier without success. This afternoon, I am taking it o MPH.

Finally, the pinion carrier was taken out at the MPH shop... it shows the difference when you have the proper setup to work...

Here's a macro photo of each of the 8 tooth...

I suppose few of us have seen one in the flesh. This was my first time too.

You can see the metal has lost its surface treatment, and the teeth had metal being torn apart.

I have ordered the one from eBay.
