|  An attempt at portals
Well i think this is my first thread so here goes. Sorry about the pictures.   So after a while and with to much time on my hands i got bored and made started thinking about portals. I found some aeroplane gearboxes and ive mounted one up.   As far as i can tell the mounts work i have managed to ram it into rocks etc and its held up with 3 wheel drive. But my prob is now i need some pinions as i managed to mangle 3 trying to drill them. So anyone know where i can get some 4 mm pinions which from what i can tell are 0.6 pitch metric 14 tooth? If not i guess ill buy some more of the origional pinions and get someone with a lathe to drill them out. Just got to get myself a landy top to fit it so i can make it look like my 1:1  clicky |

"Portals"? - so this not only gives you the extra width, and drops the wheel down a bit also? Looks like it would improve your ground clearance, if the little gearboxes themselves did'nt get hung up on anything. How tough are they going to be? I'm not nessecarily opposed to having to replace a part or two once in a while, but if they break every run or two it will get expensive. I think it's a great idea, don't get me wrong. It just utilizes a part that is not designed to undergo the type of stresses your are subjecting it to. If someone in the airplane world is making trick little aftermarket anodized aluminum gearboxes like that, that would be the ticket. Have you seen these on 1:1 trucks? I never have. Cool idea. Oh, nice real truck, too. |

Well im still waiting on sorting a pinion for the portal but hopefully in the next week. i have given it all i got with my own brute force and not shifted it so i think it will manage  . Gears are metal so recon they should hold up. Like i said just a pinion i need anyone got any ideas? |

Yea seen them on real trucks, after getting some for my truck but they expencive to say the least. Like i said its just a test and if they work im gonna get wheels with very little off set so the portal box is covered by the wheel (its just small enough to fit inside) and ill still get a track around 10 to 10.5 inches. Another advantage is reduced stress on axle components and im guessing less torque twist to. |

Those look great. They appear to be open to the elements. I might suggest using kydex to form a cover for them. I did something similar to enclose my gd600 reducer.

Yea do think they need protecting from the elements but will make sure they work first. If you imagine the centre line of the wheels level with the bottom of the diff thats how much extra clearance you get. Im from cheshire in the UK studing a masters in design at teesside university at the moment. Yea a company called maxi drive sell bolt on portals they 6500 uk pounds a set though. Still anyone got any ideas on pinions?? |

Can you turn down the shaft to fit the pinions instead of drilling the pinions?

Out in Utah I have seen the bolt-on cat tread units for 4WD trucks. So there's a gearbox with a cat tread at each wheelwell. Very similar. And I totally forgot about Unimog's, I have seen a set up similar to this on them. If you could enclose it and make it fit inside the wheel so it's out of the way, that would be even cooler. |

Maybe in YOUR hands.  Make a blanket statement like that and someone on this forum will take it from you, throw it over your head, and many faceless people will beat you down. Be happy I edited this post on my own. Granted Jeep may not be the best, but I can't afford a Mog. P.S. Awsome work on the portals! Last edited by LumTheMad; 12-06-2006 at 08:08 AM. | |
