Well, the first chips have been made! Normally we use 1:8 scale buggy diffs, with a kind of planetary gear reduction in the rear wheels, but due to the low Rpm of this engine that's not an option. Running a buggy diff without the panetary gears on an engine like this is out of the question, so I needed a bigger diff. I had a look at a 1:5 scale diff, but I thought that was just too big. Besides, I would have had to modify hat also, because these diffs use straight gears, instead of bevel gears. So, in the end I decided to make my own diff. The spider gears are aproximately the same size as those used in bigscale diffs (module 1), only I used 6 instead of 4 of them. The crown and pignon gears are huge (module 2), with a reduction of 1:1.5. The gears were bought and modified, everything else is scratch-built. When everything is finished, all the gears are going t be hardened. Completed diff: The diff next to a 1:8 scale Ofna diff. Side cover removed: Spider gears removed: Last edited by Micropuller; 12-20-2007 at 05:58 PM. |

The diff... Really nice man! I want one! Isn't there going to be a limit on how much power a given size tire can deliver to the ground? Do you plan on gearing it for some SERIOUS rpm, or slow and powerful? Looking at your ring and pinion, I would say your going for insaneo wheel speed. Correct? Also, will you be handing out safety glasses for all the dirt that is going to be flying?!! | |

| Come on man, give me a break! Where do you think these parts come from, some kind of kit? Making that diff took me the best part of my weekend Quote:

But seriously, gearing it any lower will probably cause the engine to overrev, something these big guys don't particularly like to do. I don't expect this puller to be a winner, because if I ever get it running well, it's going to be just rediculously overpowered. It's going to be more for show then go. Nah, if they just stand to the side and keep their distance, everything will probably be Ok (I hope ) Last edited by Micropuller; 10-03-2007 at 04:21 PM. | ||

Well, it's been a while, but finally here's an update on the project. The first thing that had to be done was to fire up the engine, and see what we're dealing with. So I started out with making a solid stand for it: Clamp it down and hold on tight... To say we weren't disappointed by the sound would be the understatement of the century. We were standing in a riding stable, and the next day the owner told me that the horses that were standing in another stable nearby started panicking when we started the engine! So, let's continue with the rear-axle. The first thing that had to be done was to make the pinion and drive axles and connect them to the gears. The pinion wasn't too hard to do, because the gear was big enough to simply screw it to a flange. The drive axles were harder to connect, because the diff gears are a lot smaller. At first I thought of simply welding the axles to the gears, but in the end I decided to put a pin through the axles and mill a slot in the gears. Then I made the axle-housing. The diff and the axles run on seperate ball bearings. On the outside the axles are held in place by a circlip, so they can't move in or out. I made a couple of flanges to fit the drive axles. The rims will be mounted to these. And this is what it looks like with the tires mounted: Now that's finished, I can start on the hardest part of this project, the clutch. |
