I think they are great idea; for greasing but not to leave in.

After I snapped of the head of my first one installed, I became a little cautious - as 'they' say.

I may have over tightened it, but it did break very easily and on inspection I found that the larger drilled & threaded hole for the grease nipple extended down into the bolt shank for a distance. That meant that portion of the shank was drilled out a good deal more than just the hole for the grease. The strength of he bolt was thus weakened much more and that is where my bolt broke off.

We do not know what stresses are placed on the bolts under actual use and when hitting a hole etc and we also do not know what could happen if the head came off while being ridden.

I have heard of others also expressing some concern who will only insert them for greasing and then remove them.

I do not want in any way to negate the wonderful effort by our member who organised their manufacture and distribution, but just be a little careful and consider how best to use them.

To elaborate a little more:
Quote:
larger drilled & threaded hole for the grease nipple extended down into the bolt shank for a distance
I did some measuring (metric):
The bolt is about 8mm in diameter without the threads,
The grease hole is about 2mm in diameter.
Now, that leaves plenty of remaining strength it would seem.
However, when the large nipple-threaded hole extends past the bolt head and into the shank, it is 6 mm in diameter.
That leaves only 2mm of metal in total, or 1mm of metal around the center hole at that point.

That was the situation in my case and it may not be typical of all the bolts, but are we sure?

You could remove the grease-nipple and measure how far the hole goes into the bolt past the head - that would give you an indication.

The bolts don't get a pulling action on them, it's a lateral pressure on the bolt.

iff the bolts have a 2mm grease hole and the nipple is 2mm deeper then the head, they can even snap when you torgue them with the right amount

they are 6 times weaker then the stock calculated by a friend of mine, who i did call, he has a Master in Engineering


just a warning only use them for greasing and put them in by hand

May I inject a cautionary word here.

The 'notch' is eff-all to do with lack of grease - grease isn't actually important for these bearings - there should be enough to keep crap out, but that's it. The actual surfaces that meet have no grease between them - they are static surfaces in the main, and there probably isn't a molecule of grease left between them, even after the treatment above. It's metal to metal. If there's room for grease - they're too loose.

The one single, big problem is the pre-load applied to these bearing at manufacture (and in the first iteration of the workshop manual - by workshops).

Zero pre-load - no problem for life unless the rider hits a big pot-hole or whatever. The damage is done by axial impacts, nothing more, nothing less.

This is not a mod I would bother with or give a second thought to.
Last year, as a prevention, I have greased those bearing until you see the grease coming out of the tube. The scooter had only 3000 miles and NO "notch at this time". 50 miles later I have started to experienced this "notch".....WEIRD.

I have changed the bearing myself and when I removed them I noticed that they were taotally covered by the grease (see the picture).

In my case the bearings and the race were not in a bad shape but the "notch" was there. Anyway, I have changed them and added a little bit of grease but did not overtight them (I went with Jimc recommendations). 5000 miles later no problem.

I think I have experienced the "notch" because of the excess of grease around the bearings and that the most important thing is the pre-load like JIMC has mentioned.

Now may I suggest that we all take a deep breath at this point.

THE MOST IMPORTANT thing here is to set up the pre-load to zero. Failing to do that causes "the notch".

The next item of importance (and it's a long way behind) is to grease the bearings. The grease lubricates the bearings, but more importantly, it keeps crap out. A great way to destroy antifriction bearings (roller and ball) is to allow dirt in. The way the Italians have set up the bike makes it hard to grease the bearings, and not-too-hard for dirt to get in. Hence the "lube bolts" we now have.

By all means use the lube bolts. I have, and my headstems are full of grease. However, the original bolts are holding my forks on. Why? Because you only have to grease the bearings infrequently. Why risk a reduced-strength bolt when you save yourself maybe 15min once every six months? Doesn't add up.

I am also of the opinion that I'm probably never likely to have to grease the bearings again. Ever. Why? Because the great lump of grease inside each headstem keeps weeping out the bottom bearings. Road vibrations are responsible. I have to wipe them clean about every 2 weeks. They're being flushed clean on a continuous basis. The top bearings take much less load and are well protected from the elements, so I'm not concerned about them. They'll be fine.

Executive summary:

1. Set up the preload
2. Use the lube bolts to grease the headstems
3. Put the original bolts back.

Fuoco head bearings
Thanks guys for all the usefull info posted here. I have same symptoms at 23,000km. I have one small question, do you adjust the preload on the bearings from the "grease nipple" 17mm head bolts or from the top of the column??

Once again thanx for yr help

I decided to "bite the bullet" this week-end and adjust the pre-load as previously discussed.

The plastic all came off a lot easier than I expected and I marveled at the large one piece unit that encases the front of my 400.
I slackened off the pre-load about 110 degrees as instructed and used a punch to loosen the nuts and re-tighten the lock-nut.
I even used up all the screws when putting everything back.

I had already greased the bearings via my removable grease nipples and I pumped a little more into the top bearing only as it still seeps out of the lower bearings.

Went for a test ride and the steering is now a lot lighter than before. It's hard to understand the logic from the factory of pre-loading them.

We all grumble about the little irritations and faults our scoots have, but I am really amazed at the complexity and genius of the design of the front end. The amount of design, trial and error, testing and everything involved must have been immense. We really do ride something very special, despite its faults.

PS: For the benefit of the previous questioner, the adjustment is at the very top of the steering "posts" - the nut that stops the suspension from falling out.

Personal update
I have not been active on the forum as of late do to my wife and I becoming legal guardians of 3 neighbor boys. It's a long story,some of which is juicy, but plan to return and participate once again.
I apologize about the long delay on the bolts. They are all ready to send out, I just have not had the time. Thank You for your understanding and I miss you all. TTYS!

get a can of white spray grease and use the red tube, spray as much as you can at the top and bottom bearings till you get a set of modified bolts to use.

I recognize this question... I did answer it last time you asked... I guess you never returned to that thread.

Anyway, the bearings are sold separately. Below is a link to a thread with all the info you need.

Lube Bolt set
Hi,

I'm pretty new to the forum and puchased a second hand fuoco a couple of months ago luv it but it has not been without it's problems i have just checked out this thread about the lube bolts you manufacture and have to say Genius! i live in the UK london and if possible would like to order a set of 4bolts from you?. I will be in LA from the end of this month for 3wks so it may be better to post the bolts to my cousins place where i'll be staying, please let me know if you can do this and let me know how to proceed.

Many thanks and regards,
Jake

I just wanted you to know that we are making these bolts in Greece too. In fact we have a "three wheelers club" named www.3kyklo.gr dedicated to mp3's and other three wheelers. Some dealers loved the idea and have started using the bolts just for lubrication. They don't install them permanently because they are official Piaggio Service points and it's not allowed.

I broke off a bolt on the top Paralellogrm. I bought a new Tork wrench from Harbor freight/ Set it on 40 pounds <USA>Cranked it down and it never clicked to tell that 40 had been reached. I cussed, got mad, walked around a minute and went back.

Could my Tork wrench be defective or did I just not know how to use it?

How difficult is it to get the broken end out?

What size does the replacement bolt need to be. (I cannot figure it out from the diagram at the beginning).

Is it safe to ride it about 1 mile back to my garage?

Not all torque wrenches are created equal, some, the cheaper ones you only feel a possible snap, the better one will snap loudly and feel. Never scrimp on a very precise and important tool.

did you cycle the wrench a few times before setting it and again after setting it prior to using it on a bolt? then when your done with it set it back to zero?

I'm not certain but I believe the torque is 40 nm. Not 40 lb ft

I use a bench vise and clamp an old socket in it, then attach the torque wench and pull it till it clicks and do that 3-4 times. then set the wrench at what ever setting you going too use it at and cycle it again before using it on the nut you want to torque.

This does 2 things. 1 it make sure the torque wrench is not sticking , and 2 gets you to feel when the click happens.

For storage after usage and care:


To maintain consistent accuracy, torque wrenches must be checked periodically for wear or defective parts. A properly structured preventive maintenance program optimizes tool performance and reduces unexpected downtime, thereby saving time and money.

The more often a torque wrench is used the faster it will wear or go out of calibration. Monitoring the number of cycles per day or total hours that a tool is used is the most accurate way to establish proper maintenance intervals. It is accepted that torque wrenches should be serviced in line with manufacturers recommendations or no longer than 100,000 cycles, or when a visual inspection reveals old or dry grease, parts that show signs of excessive wear, loose or unstable components.

The ratchet of a wrench should be inspected for wear, cleaned and lubricated. Periodically verify that ratchet screws are tight and that the ratchet spins freely when turned. The wrench handle should not be loose and it should be free of corrosion or lubricants when used. Failure to inspect, lubricate, adjust, and replace worn parts on wrenches can lead to premature failure.

Protect your wrench from dust, grime, chemicals and other hazards by storing the wrench properly in a case or other storage device and keep it in dry and clean place. Clean your wrench on the outside with a dry cloth. External cleaning fluid or other chemical solvents can corrode the internal lubrication of the tool, causing premature failure. If it is necessary to disassemble the wrench follow properly documented instructions provided by the manufacturer or send to a competent technician.

Most click wrenches are built with an internal spring mechanism that is compressed to against a lever. Adjustable wrenches use springs that must meet a linear capability test. After use, externally adjustable click wrenches should be turned back to minimum scale value. This helps to preserve the linearity of the spring and calibration of the wrench. All calibrated wrenches should be backed off to the minimum setting when stored. Calibrated torque wrenches use a spring with a known linear range. It is thought (and has been proven) that leaving a calibrated wrench at one setting impacts spring linearity, disallowing accurate use at other settings. It does not happen every time, but over time linearity can be impacted causing error. This is the reason for the recommendation to turn a wrench back to its minimum setting when not in use. If you use the wrench at only one setting, you might consider a "preset" version that is set at one setting. This has no scale and is set by a torque tester. It requires no adjustment to minimum and can stay set at one torque setting without issue to linearity.

A torque wrench is a precision tool and should be treated and maintained like a measuring instrument.

All right. I took the bike to a local front end alignment shop that I use. that is where I broke the bolt. Not their fault.. I bought a set of left turn ease out drills. Used a center punch so the drill bit could have a place to drill. Used a variable speed drill and went to work. worked like a charm. out came the broken bolt.

Figuring out how to take off and put back on the tupperwae was the hard part.

The tork wrench wqs not the problem, I just did not understand how to use it properly.

Took me 4 hours to take apart and put back together. 25 minutes to do the lube job. 8 minutes to pull the broken bolt.

Bought new bolts to replace the two I stressed and the one I broke.

I am back on the road.

P.S. The guy at the front end shop showed me how to set the proper pressure on the bolt.. The tork wrench worked properly. I just did not understand how to use it.











all right. I took the bike to a lo

Jumping two years, anyone still active with this mod? I would very much like to try it, I am having steering wobble issues. Does anyone on this forum still have some modified bolts they aren't using that I could acquire? Thanks much!

Jim, thank you!
dang, looks like they plagiarized their fellow countryman who came up with this, and conveniently use it to pull in money rather than address a design flaw with serious service cost.
Looks like I just found the likely cause of my scoot's presumptive steering bearing issues - previous owner rode it to Alaska, that would fit their winter riding warning. Interestingly, the dealership serviced the scoot afterward, pre-resale, and never addressed this. Thank goodness for this forum!!
