If you fellas want to stick to scale that's the proper steering wheel. doesn't need to be round or larger. There's just a small rod through the centre operating a valve under the floor.

Got the old Harley sold, B40 kits are supposed to be ready 3rd week in Jan. It's all your fault ;)

Re: Azonic Hitachi 470/Bell B50D
 

Excellent... are you buying it complete or in what state of build?

Re: Azonic Hitachi 470/Bell B50D
 

Kit/unwelded

Re: Azonic Hitachi 470/Bell B50D
 

Awesome, it was not hard to push you over the edge! :p

Really looking forward to see this, especially since you went with the kit, will it be Bell yellow?


An little update on my 470, i took it apart today for some modifications, paint and service, undercarrige will get some black powdercoating, new swing motor will be installed and will re-build the stick and bucket cylinder, i think i might have damaged them a little when first assembled, will replace all o-rings.

I also have a 4th valve coming from Frank that i will install as well, plan is to make some additional hydraulics for a tiltbucket or other hydraulic attachments.

More on this later this week i hope.

Re: Azonic Hitachi 470/Bell B50D
 

Your cyls starting to drip? My stick cyl is seeping a little bit, but I think it's mostly just when digging hard ground - run at max press constantly, don't see any pooling in easy digging.

Are going to use a hyd mechanism for your quik-tach?

I'm thinking about narrowing up my digging bucket 20 to 30% & making a GP bucket 50% or wider than stock.

Re: Azonic Hitachi 470/Bell B50D
 

Joe, can't remember if you cylinders came built or not? But it they are the same as mine, there are 6 bolts on the end, this removes the end cap, inside are two tiny rubber o rings acting as scrapper seals. I assume with all your digging and high pressure you're worn them out...?

Mine even came with spares..

http://i823.photobucket.com/albums/z...r/IMG_2265.jpg

Hope that helps?

Re: Azonic Hitachi 470/Bell B50D
 

Yes, I built my cyls too Kalle. :) I used lots of white Lithium grease installing the o-rings with a precise curved pic. I got spares too.

Seems odd though that they might fail already, I pretty sure I'm well under 100hrs and I changed oil at about 30hrs... :confused:

The brass tubing on mine is quite a bit different than yours (they did that).

Re: Azonic Hitachi 470/Bell B50D
 

The stick and bucket cyls are leaking a little, i have run between, 22-27 bars from the time i got it, now im on 25 i think. Im going to do it now that i have it apart so its fresh for the coming spring! Getting the smallest o-rings out should be a challenge! :)

Nope Joe, though i was gonna go hyd for the new one i still wanted the 4th valve for something else then just a qucik coupler, so it will most likely be a low geared motor that push the mechanism in and out.
A motor controller i have found will be used to run the motor on a 3 pos switch.
I hope to have some CAD:s from the guy who does that later this week. Will PM you about this.

I have also thought about making a larger bucket, some kind of mass bucket, with or without theets, dont know yet, also a better grading bucket will be made, my friends uncle have a plasma cutter, i will ask him to cut the pieces out, will have to make some templates first.

Re: Azonic Hitachi 470/Bell B50D
 

Got started on the extra hydraulics today, waiting on the valve so i started with some pipes on the stick...

Re: Azonic Hitachi 470/Bell B50D
 

Thumb?

Re: Azonic Hitachi 470/Bell B50D
 

No, i think i will use it for a tilt bucket or something else, no plans for a thumb yet.

Re: Azonic Hitachi 470/Bell B50D
 

An little update on the extra hyds., made the boom pipes and mounts today, now im just waiting on the nipples and some other things.

Re: Azonic Hitachi 470/Bell B50D
 

Looking good Kalle. :cool:

Is that a different hose on the bucket cyl, more flexible than what's provided in the kit originally?

Is your body tall enough to fit the vertical swing motor without cutting a hole in it?

Re: Azonic Hitachi 470/Bell B50D
 

Thx Joe!

Nope its the same, i use a heat gun to soften them up a little bit, then you can form the a little like you want, and when they get cold they hold the shape a little better.

I dont know yet really, but i think i may have to cut it up a little.

Re: Azonic Hitachi 470/Bell B50D
 

Heat gun, good to know, thanx Kalle... I tried to make mine like the OEM and it kinked!

Re: Azonic Hitachi 470/Bell B50D
 

Kalle, the additional pipe work looks neat. What are you using the make them?

Re: Azonic Hitachi 470/Bell B50D
 

Yep, works pretty good! Your welcome!

Thanks!

If you refer to the pipes, they are 4x0.5mm pipes, other then that just some brass, silver solder och a tube bender, but most importand, my hands! haha!

Re: Azonic Hitachi 470/Bell B50D
 

Here is the new quick coupler im working on.

Re: Azonic Hitachi 470/Bell B50D
 

Looks very nice Kalle.

I bet you are happy.. I want to see and hear more videos og it in wet snow.. it sounds great!

Re: Azonic Hitachi 470/Bell B50D
 

Looks too purty... squirts some oil at it, then empty your vaccum into the box. :D

Re: Azonic Hitachi 470/Bell B50D
 

Looks very shinny, Joe I just laughed my _ _ _ off at you comment, I think if he did dump oil on it and then the vaccum it would still be cleaner than your iron... lol

Greg

Re: Azonic Hitachi 470/Bell B50D
 

Nice, get it dirty! It's video time, I can see it now.... Up to the hubs in mud, dirt running off each side, gettin' it done. Great job.

Ben

Re: Azonic Hitachi 470/Bell B50D
 

Thanks Elliot!

Im sure happy its done and it looks good, i will make some kind of snow video as soon as im done with the 470, there is always something you want to finish before you can play! :)

Thx Joe,

Haha! My vaccum bag is always empty, i rather stay in the garage then go home to vaccum cleaning my flat! :) It will get dirty as soon as the white stuff goes away!

Thx! Im pretty sure youre right about that last scentence! :)

Thx!

As soon as spring comes around i will get out and get it dirty for sure, i think i have the perfect spot for some mudding! :)

Re: Azonic Hitachi 470/Bell B50D
 

Very well done. Great looking machine!

Re: Azonic Hitachi 470/Bell B50D
 

A little more done on my quick coupler, i painted it, added a sticker of a Swedish brand that makes rototilts, attachments and quick couplers, I also tryed it out in the snow yesterday, it got all wet, i just let it sit over the night to see it there would be any rust problems in the cylinder holes, i did lube the cylinders, worked all good when i tryed the coupler next day.

So im very happy all in all so far with it, im going to waterproof the cover part and do a water test later on to see how waterproof it can get.

Here is how it lookes now, ill try to make a better video this weekend.

Re: Azonic Hitachi 470/Bell B50D
 

Truck looks great --- but you already know it is too clean! The electric quick coupler is a real gem. Very clean install and looks to be positive-locking - sometimes a problem on the real ones.
Great job on both!

Re: Azonic Hitachi 470/Bell B50D
 

Thx! Yea, i did get it stuck the other day in a very sticky mud, was even hard to pull out by hands, its dirty now! :)

The coupler works good for me this far, might be different in 1:1:s, do they get stuck or what?


I had some playtime yesterday, i did a trench and it was a lot of fun, especially to let the water through from the water puddle! :)

A lot of the material i filmed was direct in the sun so i had to scrap alot of video.

Re: Azonic Hitachi 470/Bell B50D
 

I've had trouble with my mechanical coupler getting jammed with mud.
I have a Cat 305C CR mini excavator.
Yes digging drain ditches can be a pain due to mud, packing everywhere!
Look's great so far!
Cheer's, Neil.

Re: Azonic Hitachi 470/Bell B50D
 

Good video-your models look good and seem to work really well. Nice job!

Re: Azonic Hitachi 470/Bell B50D
 

Yes i can understand that a mechanical coupler get stuck in the mud! :) I have operated a few different Volvo 140:s and they had hyd couplers and they got stuck as well sometimes when the bucket had sat to long in the coupler and rust and other effects made it stuck.

But some "shaking" with the bucket and some light pressing made it come loose at last. :)

Shouldnt be a problem on the scale coupler i hope!

Thanks alot! :)


I also turned down 2 more comfortable stickgrips for my radio, turned out pretty good, im all new to machining parts, i wanted to make them a little concave where i hold my fingers, but i couldnt figure out how to make it concave on the manual lathe, very hard to turn it even over the whole part, any tips?

Re: Azonic Hitachi 470/Bell B50D
 

Nice vid Kalle and nice canal as well. Its nice to dig with a purpose as well. Where was the Bell ?

Re: Azonic Hitachi 470/Bell B50D
 

Thanks elliot!

I cant dig without a purpose, sure i can but i get bored after 5min, i have to do something that will be something, thats much more fun! :)

The Bell was in the background, there will be a cleaning up video from the same place where i did the trench, the Bell will take care of that! :)
