Now I have started with the m45 gearbox. Goal: get the gearbox weight down.
I've taken out everything that is not needed. So the only thing that remains is the shaft with the synchronization ring. This is to be able to put it in 4th gear and neutral. I'm pretty happy with the result, although I have not weighed anything yet.

Nice !
I don't really hear something wrong with the engine (maybe the video do not help) but i see some blowby You run on normal diesel fuel or a specific "fuel" ? Couldn't be just a steel cover plate loose or something ? How is the oil ?

Thanks!
It's an incredibly loud noise from the engine, most of it is knocking sound, and something more like bad vibration. I guess it's a combination of rod knock, worn piston rings and bad timing on both cam and IP. It is normal diesel fuel, but if there is something i can put into the diesel to get more heat, but the fuel still classifies as diesel i would like to hear about it :P Cover plate is making sound, but the engine is so loud on idle that you don't hear the cover plate. Thats how bad the engine runs. And the oil is changed often, but this year i have not change the oiled because the engine have runned for about 15 minutes this year. Also, I have a question for you. Do you know of someone who has light reduction gear for sale. Or someone who can make gears on demand? |

For you gearbox ?
weight reduction ? I don't know i have no contacts. i would say a serious machine shop could do it. it's a "simple" machining job on the gears or splines to reduce weight. I can't help you but i' will follow your work on this machine. Very interesting.

the gearbox doesn't need any more gears, that is only going to use 1:1 gearing (4th gear). And because of that i have to have reduction gears on the hubs (where you bolt the wheels on) to get the right speed on the wheels. I haven't calculated on gear ratios yet, but i should perhaps do that soon :P
[ATTACH=CONFIG]290[/ATTACH] And another question... The rear end is going to be where i can change gear ratios, and therefore i should have an rear end that have alot of different ratios so i can change to what ever i need. BMW have one or 2 diff housing that fits with alot of ratios, but is there any other brands that could be interesting to look at? |

quite easy to find and cheaper than bmw i guess. They make a lot of 4x4 and they should be a bit stronger than the dana 30 copy of the volvo 240 or the real jeep one.

If anyone have a list over the different diff ratios for the 1030 and the 1031, i would appreciate to look at it :-) |
