Chevrolet Crankshaft Parts Questions & Experts Answers

  • Q: What steps must be taken to remove the crankshaft from the engine after it has been taken out on Chevrolet Astro?
    A: The crankshaft can only be removed after the engine has been taken out of the vehicle, assuming that the flywheel or driveplate, vibration damper/crankshaft pulley hub, timing chain (for V6 engines), oil pan, oil pump, and piston/connecting rod assemblies have been detached. For engines with a one-piece rear main oil seal, the seal housing must be unbolted from the block prior to crankshaft removal. First, check the end play by mounting a dial indicator aligned with the crankshaft and touching one of the crank throws. Push the crankshaft to the rear and zero the dial indicator, then pry it to the front and note the reading, which indicates the end play. If the end play exceeds specifications, inspect the thrust surfaces for wear; if no wear is found, new main bearings may resolve the issue. If a dial indicator is unavailable, feeler gauges can be used by prying the crankshaft to the front and measuring the clearance between the crankshaft and the thrust main bearing. Check the main bearing caps for markings indicating their locations, numbering them consecutively from front to rear if necessary, and loosen the bolts gradually until they can be removed by hand. Gently tap the caps with a soft-face hammer to separate them from the block, using the bolts as levers if needed, and take care not to drop the bearing inserts. Finally, lift the crankshaft out of the engine, ideally with assistance, and return the bearing inserts to their positions in the block and main bearing caps, tightening the bolts finger tight.
  • Q: How to remove the Crankshaft Seal and Crankshaft in V8 engine on Chevrolet Caprice?
    A: The crankshaft and main bearings ought not to be removed except when the engine has been removed from the car, and the engine should initially be dismantled. It is advisable that each of the five main bearing caps should be labeled to show where they belong in the engine block; if this is done, indentations as would be done with the connecting rods and caps should be made. After loosening the main bearing caps they should each be removed from the crankshaft with their corresponding bearing and should be laid on another work bench numbered as per the position of the bearing caps on the engine. The crankshaft can then be slowly pulled out with the use of lifters so as not to wreck the engine block. The two halve of the rear main bearing oil seal has to be detached, The crank shaft main bearings together with the cylinder block and main bearing caps should be withdrawn in such a manner that they will not be mixed since they have their own positions. Last, the crankshaft gear at the front must be removed which is best to be done with a puller intended for this job.
  • Q: How to inspect and repair a crankshaft on Chevrolet Tracker?
    A: Remove all burrs from the crankshaft oil holes with a stone, file or scraper, ensuring the oil holes are chamfered to prevent damage to new bearings. Check the main and connecting rod bearing journals for uneven wear, scoring, pits and cracks. Rub a penny across each journal several times to reveal its condition-if copper rubs off and is embedded in the crankshaft, the journals should be reground. Clean the crankshaft with solvent and dry it with compressed air, using a stiff brush to clean the oil holes and flush them with solvent. Check the rest of the crankshaft for cracks and other damage, which should be revealed by mag-nafluxing. Measure the diameter of the main and connecting rod journals with a micrometer and compare the results to the Specifications. If the crankshaft journals are damaged, tapered, out of round or worn beyond the limits given in the Specifications, have the crankshaft reground by an automotive machine shop and use the correct size bearing inserts if the crankshaft is reconditioned. Check the oil seal journals at each end of the crankshaft for wear and damage. If the seal has worn a groove in the journal, or if it's nicked or scratched, the new seal may leak when the engine is reassembled. In some cases, an automotive machine shop may be able to repair the journal by pressing on a thin sleeve. If repair isn't feasible, a new or different crankshaft should be installed. Examine the main and rod bearing inserts.
