You will need:


- Set of standard screwdrivers
- Variator holding tool - http://www.modernvespa.com/forum/topic47278
- Torque wrench
- Impact wrench - not necessary but it will make your life easier.
- 27mm & 21mm 6 sided sockets for your torque wrench.
- Something to lock the rear wheel with - wooden wedge



Start with taking 4 black screws which hold transmission plastic cover out..


You gonna have to remove air filter cover for the transmission plastic cover to come off.. It should be 9 screws


Take the plastic round cover off using screw driver...


Finally the plastic cover is coming off..


Undo the driven pulley nut using either impact wrench or any other wrench.
21mm 6 sided socket - I used 1/2'' drive and it worked great.


Now the aluminum transmission cover screws, 7 smaller ones and 4 bigger ones..


Transmission cover off..


Attach variator holding tool. This one is from company called Buzzetti. More info here http://www.modernvespa.com/forum/topic47278


Undo drive pulley nut. Best for this is an impact wrench as it is very tight. 27mm 6 sided socket - I used 1/2'' drive and it worked great.


Remember which washer goes where. The bigger one no. 1 first than smaller no.2


Behind outer variator pulley you will find another washer..


Check the driving belt... this one looks OK after 3333 km :)


Variator with OEM rollers


Bushing and the variator housing with "shoes"


OEM variator and J COSTA


Housings


OEM variator


J COSTA


Notice that behind the variator is "another" washer. Just leave that on..


Its ON!

.......................................


Put it all back on in reverse order BE VERY CAREFUL WITH ORDER OF WASHERS !!!! Torque the drive pulley nut - torque 160 - 175 Nm.
Make sure that the drive belt is down in between the clutch pulley halves (It is not like that in the picture!) otherwise you


Put no.1 washer on, then the aluminum transmission cover and then washer 2 and 3. Just to confirm no. 1 washer goes UNDER transmission cover!


Torque the Driven pulley nut - torque 92 - 100 Nm. You need to lock the rear wheel.I used the handle of the big axe + holding the rear brake + parking brake

I will never attempt to do this myself but wow. Looking at these pictures sure helps me understand the mechanics to some degree some part of what makes my scoot go. This is really fascinating. Bloody brilliant.

Awesome tutorial. I had just recently taken the plunge to get inside my 250. Then looked at my new 400 from the outside and was wondering how to get the cover off as it is different.

Do not see in the pictures anywhere to use a holding tool for the clutch nut. Holding the rear wheel is probably fine, but the tool for the 250 is low cost.

Has anyone found a source that has the variator tool in stock for delivery to U.S.?

Good write up, but can I add a couple of points.

When undoing the clutch nut use an offset ring spanner on the nut. The shaft has an hexagon on it to allow the use of a socket and wrench to hold the shaft still.

For tightening the clutch nut I found with the weight of the bike on the back wheel and parking brake applied that was enough to be able to torque the nut up with a torque wrench.

When tightening the variator nut, make sure that the drive belt is down in between the clutch pulley halves (doesn't look like it is in the picture) otherwise you risk tightening the outer pulley half against the belt. Then when the belt moves up the ramps the nut is not as tight as you thought. Resulting in the variator nut then working loose.

There is s bug on this forum which doesn't let me to update the note under the picture in full. I can add it and preview it fine, but once I submit it's just not there. I've tried everything including re-adding the whole post and using a different browser. Is there any admin arround please?

Also, are you going to write about your impressions of the scooter w/ the J Costa?

The axe handle is jammed against the bottom of the transmission itself, not the black cover (if I recall). Also with parking + rear brake applied it didn't put as much strain on it (that was my feeling anyway).

You can find my impressions with J COSTA here http://www.modernvespa.com/forum/topic47908

My opinion is that it performs differently on 400 & 500. Someone already pointed out that lighter weights would be more suitable for 400 but as far as I know J COSTA ships only one standard set of weights for both 400 & 500.
Next thing for me would be to experiment with Dr. Pulley HiT clutch + Sliding rollers and see how that performs.
Main thing I am aiming for is fast acceleration from stand still

Looking forward to that, too.

It's nice to see someone who's technically, as well as financially confident enough to experiment with new products like that, especially in this declining economy.

Oops, I am really sorry to hear about your loss of employment. Is that how they call it across the pond-- "made redundant", that's cold! Keep looking, something better will come. You seem like a creative type, a fighter and a survivor (with good humor). In this economy, I guess no one should feel too surprised being laid off, let go, or "made redundant". I go to work everyday accepting the fact that "today could be my last day", seriously.

Cost-cutting has really gone mad all over the place, because it is always easier to do that than to find out why the business is failing (I've been to the chopping block once before so I know; and many times I have been on the other end of the block, so perhaps it's bad karma). I hope you will leave with some sort of benefit package; at least you don't work for British Airways, they're asking employees to work four weeks for free! Oh, man, you don't work for BA, do you, if so, I am really, really sorry?

Good news
I wrote Motorsport Scooters (scooterwest.com) a week or so ago asking about the Buzzetti variator holder for the 400/500 Master engine (part #5446) and was told they don't plan to carry it. So I wrote to Buzzetti asking for a U.S. distributor, and they referred me back to Steve @ Motorsport.

Well waddaya know, here's his reply:

I'm glad this email made it's way to my desk. I'm in the process of

You can let all your fellow MP3 owners know that we will have them

An absolutely excellent description and visual aid. Full marks.

Addendum for those with more long-legged bikes - while you have access to it, check that the idler pulley is spinning freely and without any noise. The bearings in these can fail in various ways leading to hugely increased belt wear. Just spin the pulley with your fingers - anything suspect and get it checked more carefully. Replacement bearings are a standard size (so no OEM part necessarily required) so cheap and easy to replace.

Joe, I printed your post and pictures. I then used them step by step to take my variator off and replace the rollers with Dr Pulley 15 gram sliders. Great tutorial and thank you for making my task easier with good instructions.

Your post is the type help that truely makes MV a great source of information for the MP3.

THANK YOU

PS I will report on the results of the sliders when I have time to use them a bit. Quick test ride before dinner was a good first impression.

I used these instructions to install the J Costa Variator on my MP3 500 today. It made the installation smoother than the variator itself.

Thank you!

One note.....I only had one washer on the exterior of the aluminum housing (rear nut) instead of two like you show on the 400.

Joe Bulva - I was wondering if you might be able to answer a couple of questions concerning the OEM rollers.
1. I notice they sell on-line different sizes for roller weights: 15x2, 16x3, 17x12, etc. Do you know the actual size of the OEM rollers use on the Mp3 400? I like to get the same OEM rollers to replace mine old ones.
2. Where can I purchase these OEm rollers? I can't seem to find them on-line anywhere. The rollers I found are for MP3 250 or MP3 500.
Great illustrations by the way. Thanks for the step-by-step instructions.

You can only get OEM parts from a dealer, try here for OEM parts.

Just replaced my belt and weights (with Dr. Pulley sliders) today. Used both the horribly translated OEM service manual and Joe Bulva's instructions here. Job went very smoothly. The only head-scratching came when I needed to get the belt seated inside the dishes on the clutch side so there would be enough slack on the variator side.

Thanks again to Joe Bulva for the tutorial.

More notes:

* The M6 screws on the transmission case had 8mm heads; the M8 screws, 10mm. The hex shaft on the clutch side is also 10mm.

* I couldn't find a 20mm offset ("misaligned" as they call it in the manual) wrench for the transmission case (clutch) nut, but 13/16" worked perfectly.

* The variator nut is 27mm, which I also didn't have, but a 1-1/16" six-point socket was a very good fit.

I always wondered why they made oddball SAE sizes like 15/16" and 1-1/16". When would either be better than a 1"? Maybe they did it on purpose to approximate metric sizes? I suspect that metric socket and combination sets typically skip over 20mm because of the wide availability of 13/16". Likewise 19mm being relatively hard to find (here in the U.S., anyway) because it's a match for 3/4".

* Page ENG-3 of the MP3-400 service manual says "Remove the six M6 screws" from the transmission case. That is an error; there are seven screws, just as it says on page ENG-18.

By the time you've done it ten times there'll only be five.

Give Joe lots of Karma.

Excellent post! I printed it as a pdf file and put it away in my Piaggio folder even though the dealer already installed my J Costa. You never know what will come up.

JCosta Tutorial
Brilliant piece. Thank you for the effort.

Does anybody care to advise me with regard to slider weights for my 500 if I even have a choice with the Jcosta. I am after acceleration above all else, so what can I expect?
