Yeah, it is kind of slow for a two pump compressor, my present solution moves pistons a lot faster: It fits right where the differential should be and the motor serves as a bit of counterweight instead of the fake piston engine. LXF file download: File

I'm very intrigued by your design and it looks quite promising. Any chance you can take better photos or make an ldd file?

You're right about the batterry box, it fits nicely where the manual pumps used to be, but you're over estimating the available space in the front where the fake engine is. It's only three studs wide (even if you try to squeze the pump in vertically, the tubes coming from the nozzle would obstruct the front end loaders motion when going up or down) so the only thing that fits there is an airtank or M motor. So in my opinion the only place where you can put the pumps is where the differential and the geartrain for the motor used to be. But maybe you're right and I am not thinking out of the box enough... It would be great if you would take the time and try out your theory, that is if you can put your current projects aside for a short while... @trekman: You wouldn't have a photo of your solution laying around would you? P.S. I did try gearing up the single pump compressor from 1:1 to 1:1.667 and it does help to bring some extra air into the system. I'll take a photo of my solution during the day when the lighting is better.

Hi guys, I have a question for you: Has any of you modified or seen a 8455 backhoe with a two pump compressor and battery onboard? I managed to get two pumps inside by removing the differential and installed an M motor instead of fake engine, but I think it could be done better since my "by product" was decreased steering lock which already isn't great . One pump is quite easy to install (but barely sufficient, since the thing has 10 pneumatic rams), but I would really love to see a well braced two pump design without compromising the look of the machine. I found some videos on youtube but those modifications where either just adding an airtank to manual pumps or were nowhere as elegant (parts sticking outside of the vehicle for instance) as I would like to see it . I know it's quite an old set and there isn't much chance that people here are still occupied by it (especially with the Unimog and all the newer sets) but maybe somebody found a solution once and would be prepared to share it.

Now that I looked at Daihatsu I agree with you..

I don't know whether is it just me, but it reminds me of the old VW Beetle
