your crank case does not take oil at all. your transmission however will take usually 1 to 1.5 quarts of approved transmission oil.
If it's a 4 stroke there is no mixing oil and gas. the olny oil is in the crank case
the crank sensor "tells" the computer what piston is at the "power stroke" and what coil to fire also the next cylinder that is going to need fuel.
-Low maintainence(no crank case oil to change or valves to set) -Simple in design (VERY easy to rebuild) -The ability to rev much higher than a 4-stroke(less minor shifting) -Impressive "snap" during the power band -Much less moving parts than a 4-stroke A 2-stroke engine fires on every complete engine cycle giving it, in theory, twice the power of a 4-stroke. Unfortunately, due to the engine design restrictions, the 2-stroke's power only becomes available at higher RPMs. At low RPMs 2-stroke engines are clunky and gutless. So, if you ride aggressive, your always on the throttle, you need that quick pick up often, you will benifit from it.
There are new cranks from the aftermarket for this. Check with Summit, Jeg's, or similar. You can also use a crank from a 400, but the main journals will need to be modified to fit the block. The stroke is 3.75".
For most lawn mowers, especially those with a 2-stroke engine, the petrol and gas are mixed to ensure lubrication of moving parts. 4-stroke engines (as commonly found on ride on mowers), usually have the oil and petrol separated. If you have a 4-stroke engine, then you need to disassemble it and replace the piston rings to stop the petrol from leaking into the crank case.
Well the first necessary piece of information I would need to know is: Is it a two stroke or four stroke engine? I assume its four stroke as I'm sure you know that you need to mix two stroke oil with petrol and then put it in the tank if it's a two stroke. In that case, 25 to 30ml of two stroke oil to a litre of petrol is perfect. On the otherhand, if it is a four stroke, 300-400 ml of oil should be about right.
You will need to fix the leaking crank case for the vehicle function properly again
You need to bclear, does it crank or not crank?----for starters.
A 1994 Sea-Doo is a 2-stroke engine.. it has no Crank case oil.. Just oil in the Fuel.. either via Oil tank or Pre-Mix.. the oil that is in the fuel lubricates the entire engine.
a jeep Cherokee need 220 volts to run
350 and 305 cranks have the same stroke (3.48") so putting a 350 crank into a 305 won't change the ci at all. A 400 crank has a 3.75" stroke, so using that crank in a 305 would make a 329 ci engine. However, in either case you'd have to have the crank re-balanced to work with the lighter 305 pistons. In the case of the 400, the crank journals are larger (2.65") so they'd have to be machined down to 2.45" to fit in a 305 (or 350). A machine shop can do that work (turning down the journals and balancing the crank) but you can also buy reasonably priced aftermarket 3.75" stroke cranks from companies like Scat and Eagle that are made to fit the 305 (actually the 350, but there's no difference in terms of aftermarket cranks) right out of the box. But even in those cases you'd still need to have the crank balanced for your pistons and rotating assembly. I have a 336 ci engine that started life as a 305, but now has a 3.75" stroke crank (same as a 400) and 3.776" pistons. It's not a cheap way to get cubic inches, but if you already have a 305 block and are insistent on making the most of it for whatever reason, it can be made into a nice engine. I did A LOT of work on my heads (aluminum Trick Flows) to maximize them to work with the 3.776" bore. The 305 has a small bore - it can work for performance, but you have to know your stuff and do your research.
I dont think their is one (crankshafts usually sit in oil-they are extremely heavy metal and rotate very fast...your rpms measure how many times the crank makes a 360degree rotation in a single minute.....)but Lucky for us.......A crankshaft does not need a sensor....if you have failure, your engine wont start. Oh yeah, the 4-stroke cycle is completed when the crank spins a full 720degrees-180per stroke.
