Determining Gear Ratio of 2008 Sprinter 906 313 CDI Max Single Wheels Without Case Back

Question

Hello, I do not know what the ratio of the bridge I have in the sprinter 906 2008 313 cdi max single wheels. I know there should be a sign - but there is no, some number is there, but it's not readable. I would like to do without unscrewing the case back and counting the modes, is it...

pick up one wheel, turn the shaft count the shaft revolutions for 2 wheel revolutions. With one wheel raised, the differential gears double the speed of the other wheel. This is my concept

I assumed 46:11 is slower, probably the original was 51:13 but there was a problem at speeds over 50 km / h. There is silence only when you add the gas gently and release the pedal gently, when you add the gas more or when you let it go completely, what could it be?

probably scrap, used to pour sawdust into oil to sell something like that.

Thank you, buddy for the advice. I will wring out, fill with sawdust and sell it. But now the question - what sawdust ?? from a saw? chips? have you sprinkled dust? from what wood? I only have pine, spruce, linden, larch, alder, what is the moisture content of sawdust ?? 10% is enough? :cunning:

But despite the sale, I would like to know what is wrong with him and I do not want to look inside. But I guess that's what this forum is all about, so I'm asking.

The original gear ratio can be read from the VIN. It is also stamped on a flat surface by the lid. There is no plaque.

and what can be wrong with the old transmission that howls? The wheels are worn and patted. The new wheels have the shape of the teeth and their inclination that as a result of contact, the contact points when rotating these wheels move as if it were rolling, and worn teeth do not just tap it smoothly. You can probably ride but it annoys howling. Sawdust is such a rude way, but it helps. I just don't know how long because I only know it from stories.

I replaced the bridge because the old one was crooked and the tires were cut, but it was quiet, can the gears be changed? the old bridge was 51:13 present (howling) 46:11

jariko · Answer

now have the old bridge taken out and you have not thought about straightening it? Big press or steel rail and hydraulic jack? The parallelism of the wheels can be checked with very high accuracy with two laser pointers. When you attach the lasers to the drums, you read the discs, you shine forward and on the board you mark the distance, you turn the discs 180 degrees and the back should be the same distance. Or support these drums with trestles and when you turn the bridge casing, the lasers should not travel on the board, they should glow in fixed points then you have parallel circles. The bridges are straightening, maybe you can hit the companies.
