If some dimensions do not match, mark them and send the crankshaft to a machine shop to have it resurfaced. Then measure the crankshaft again so that you can replace the bearings to get the crank to bearing clearance within specification. Step 9: Finish disassembly Remove the core plugs, br...
The fuel-injection systems in today's cars rely on oxygen sensors in the exhaust to determine if the air-to-fuel ratio is correct, so they will automatically increase the fuel flow if a turbo is added. If a turbocharger with too much boost is added to a fuel-injected car, the system ...
Your crankshaft flange, in all probability, will need micro polishing to ra 10 to 20 micro-inch (.25 to .50 um) specifications. This could result in the flange diameter being less than 4.750" However, from various technical articles I have read, we have an allowable tolerance shaft size o...
Movement of the piston down in the cylinder then rotates the crankshaft. Connecting Rod: Between the piston and the crankshaft is a connecting rod. At the larger end of the connecting rod is a bearing that allows rotation around the moving crankshaft. The small end is attached to the piston...
You can monitor the oil level on your dipstick for 3,000 miles to determine if the deflector or plug would be needed, but chances are you won’t based on the TSB. Keith Belair says: June 6, 2018 at 9:23 pm yep, you are 100% Right, I called a local saab shop and ...
For a tractor without a driveshaft/clutch assembly, to determine the exact length of the driveshaft, with engine fastened to the tractor frame, measure between the end of the crankshaft threads or bolt head to the input shaft in the transaxle (or creeper drive input shaft), then subtract 1...
Shorter rods, revised shorter stroke crank = lower compression. Anything that makes the combustion chamber larger will lower the compression ratio if the pistons travel a shorter distance and do less "compressing". Therefore a crankshaft with reduced stroke is what you need to reduce the compression...
materials analysis is required to determine the size of the individual components in the engine so that they can withstand the induced stress. Machine design is required to translate the thermodynamic cycle into a working engine. Each of these design requirements involves tremendous amounts of ...
