Hi Guys, Selling my basically un-started project: https://www.dieselbikeforum.com/viewtopic.php?f=31&t=3399&sid=d03f7d493443b9801467ecd1bc25c243 So... Kubota Z482 in full working order (with transport frame) as per this thread so no hiding anything here and also the brand new CVTech Transmis...

Thought I'd revive my dead thread with a for sale notice... So... Kubota Z482 in full working order (with transport frame) as per this thread so no hiding anything here and also the brand new CVTech Transmission. £1000 OVNO takes the package. Thought id offer it up on here before listing on eBay as ...

Been a while since I gave an update but with very good reason. So... That false dipstick reading... Basically the following day from my last update I fired it up to warm it up prior to draining the oil in preparation of a service, about 5 minutes of it ticking over it started knocking like a really ...

Also.....

This is the pulley set I have bought from them new - if your pulleys part numbers match these part numbers then you can use any one of the belts mentioned in the drawing depending on your C/C distance.

Hi Alex, Got your PM but thought I'd post my reply on here to benefit all. Turns out my original pulley set was incorrect for the vehicle it was fitted too but CVTech sent me this e-mail which I'm sure will help you, You can confirm this belt is correct for your pulleys buy the pulley part numbers i...

Hot off the CVTech press :lol: I was surprised that the pulley faces don't actually appear to be either machined, ground or lapped from new, albeit the casting is very high quality and they have been dynamically balanced, I can only assume they do this so the belt beds its own surface after all the ...

OK quick update, (maybe not so quick) While talking to a lovely lady called Xavier at CVTech Europe I have discovered that the MORON who had the car before me had replaced the driven pulley with one from another vehicle (Ligier or Microcar, maybe petrol model of Aixam) not only this but he was using...

To calculate the circumference of our wheels I just did: width x aspect ratio % x 2 + rim diameter x Pi I really need to buy my donor bike and measure the actual rolling circumference with some chalk lines and tape measure or use a tailors tape and wrap it round the wheel to give me a true measureme...

Hi Alex, I have read your post previously regarding the bushings and it seems a very novel solution 8) similar to the restrictor rings used on mopeds/scooters CVT's. Out of curiosity why put a restrictor ring in the driven pulley too? As the Driver is the one that controls the transition of the rear...

Hi Ron,

Thanks for your input however I think you have misinterpreted what I need to do,
If I dialled up the max rpm to say 4000 I would be in an even worse situation as my jackshaft would be at 6800rpm meaning I would need an even bigger reduction ratio.

Hi Guys, Got a bit of an issue plenty of you will have already overcome so looking for advice. I have an Kubota Z482 engine and CVT package from an Aixam, the CVT has an overdrive of 1:1.7 meaning that when the engine is at full chat 3600rpm the driven side of the CVT will be at 6120rpm. I am reckon...

Sorted it :) Cheers for the advice, The link is working fine and will allow you to download the CAD Model, There is no "preview" available as its a .stp file but it downloads without issue. Having said that, if you have a problem comment on this thread and i'll try to sort it, for some rea...

I appreciate the concern, My original e-mail I sent them stated "I wasn't after anything commercially sensitive" just the package the OEMs would receive so I could use there engine in my design. The NDA there were referencing was Aixams NDA there was absolutely no mention of anything else ...

So... the guy I was speaking too at Kubota check the drawings against my serial number and came back saying; "The serial number that has been provided is from a Aixam-Mega and due to our Non-Disclosure Agreement I cannot send you any CAD files or Technical Drawings" Then proceeded to try a...

I'm gathering as much info as possible to make my powertrain as best as I possibly can do and in the throws of this I have got the complete Applications Manual and Drawings for the Kubota SuperMini Series of Engines (Z482, Z602, D722, D902) including the "Technical Information Document" fo...

As Promised... See Attached...
Hopefully I will get the Technical Drawings and CAD Model for the Z482 tomorrow as previously stated.
I will upload as soon as I have them

Please find attached the complete Application Manuals for the Kubota SuperMini Series of engines. These cover the Z482, Z602, D722 & D902. The documents include everything needed to calculate the correct exhaust pipe dimensions for optimal performance, likewise with the Intake. (think turbo char...

Wow... So many responses so soon! thanks everyone for all your valued input. This last week has been very disappointing, was due to fly out to Amsterdam with Ellie on Sunday but 30 mins prior to boarding @ Birmingham flight was cancelled due to the snow. Mangaged to get flights for the following mor...

Well... What can I say. After 3.5 years of being a forum member and countless hours of fantasising about building my own diesel bike I have finally pushed the proverbial button for launch! I feel I have learnt a lot from all of you guys on the forum through reading your posts and answering mine so f...

Yeah I'm planning on coming down to have a mooch around and some good conversation, Albeit I'll be in my car (surprise surprise.... that's a diesel). It's mine and my new girlfriends first anniversary that weekend so will be staying at a hotel I imgine as she's been good enough to agree to let me co...

Hello everyone, I have been chewing this over in my head a bit recently and wondering if anyone has experience of the matter, Basically a CVT adjusts based on engine speed vs load to keep the engine speed at a consistent RPM. The governor in the Diesel engine adjusts the amount of fuel delivered to ...

I have also just read this book, bought it to take on holiday with me, great read by the way I found Paul carter to be very funny :) but it did sound like the uni made a bit of a hash of designing the drive system, maybe they got the drive alignment wrong or the CVT used simply wasn't the right one ...

I think the thing that we all need to remember is that CVT's work on centrifugal force, against a contrast spring to keep the engine at a constant velocity. What you are saying BertTrack is correct, as without the higher RPM's the CVT's weights/cams aren't producing sufficient Centrifugal force to p...

I am looking into mounting it onto a piaggio zip 50cc frame with 10inch wheels (I have 2 scrappers at the bottom of my garden from my pedding days) :lol: and making a new swinging arm in place of the standard engine and transmission, the flat foot rest lends its self to mounting one of these engines...

Right then guy's! First things first before I go into why we can use these particular cheap and plentiful CVT's..... You may get a little lost in my explanations but please bare with me as it will all come together at the end... Engine power is measured in Torque, weather it be in ft/lb's or Nm. The...
