K5 engine crankshaft specifications

you would have to get the foundry bill of material for that crankshaft
finding the casting foundry will be a job in itself
however crank shafts are cast to a engineering standard (throw distance) and are then ground to a standard size on the big ends and main journals
what ever con rods that are used depends on the block that the crank shaft is installed in as different piston diameters require different strength conrods
the casting number is just a batch number so it may prove a dead end if you are relying on it to get information
where I would start looking is at a engineering shop that regrinds crank shafts as they may have original specs for gm cranks and that number just may indicate what block it was made for and then you may get a heading as to where to look

Could you supply vehicle detail information ? Year, make, model and engine size ? Check fuses and wiring to start out. You could have a bad camshaft or crankshaft sensor. Difficult to determine with very little information. Would also help if you tell us how did the problem begin and what have you done to it so far.

Crankshaft Position - Camshaft Position Correlation
What does this mean? OBD Code P0016refers to
The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position. The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.
Symptoms Possible sumptoms of OBD code P0016
Malfunction Indicator Lamp (MIL) illumination The engine may run but with reduced performance The engine may crank but not start The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged The engine may start and run, but poorly
Causes Possible causes of OBD code P0016
Timing chain stretched, or timing belt skipped a tooth due to wear Misalignment of timing belt/chain Tone ring on crankshaft slipped/broken Tone ring on camshaft slipped/broken Bad crank sensor Bad cam sensor Damaged wiring to crank/cam sensor Timing belt/chain tensioner damaged
Possible Solutions First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck. If you have access to a scope, check the cam and crank patterns. If a pattern is missing, suspect a bad sensor or a slipping tone ring. Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they're not loose or damaged or that they haven't sheared the key that aligns them. If they are properly installed, replace the sensor. If the signal appears normal, then check the timing chain/belt for proper alignment. If it's misaligned, check for a damaged tensioner that may have allowed the chain/belt to slip a tooth or several teeth. Also check that the belt/chain isn't stretched. Repair and recheck.

Connecting Rod's are VERY SPECIFIC for each engine. In Addition to getting the Right STROKE, Piston Pin Size, and Crankshaft Size, you need to make sure to get the Correct Bearings for the Crank. If you are not going to remove the Crank from the Engine, your BEST Option is going to be Purchasing a NEW Push Rod.

Simple answer is NO!

The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.

The crankshaft sensor is part of the primary ignition system and functions as the "trigger".

Symptoms of a P0016 will or may include:

* The engine may run but with reduced performance
* The engine may crank but not start
* The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged
* The engine may start and run, but poorly

* Misalignment of timing belt/chain
* Tone ring on crankshaft slipped/broken
* Tone ring on camshaft slipped/broken
* Bad crank sensor
* Bad cam sensor
* Damaged wiring to crank/cam sensor
* Timing belt/chain tensioner damaged

Hope helps.

thats a good un? ok standard bearings are a standard size,,,over size bearings are smaller in the center to make up for the metal that has been removed from when the bearing was re-fased
ie: ground down to smooth it off so its flat again,,,,,now you can fit oversized bearings on a standerd bearing becouse they would be far to tight and would lock the bearing up,,,,so you need to re-grind the bearing serfice or fit standerd bearings back in,,,only if the shaft is a good one?
i hope this has help you out

Hope this helps (remember to rate and comment this answer).

While tough to say from this vantage point it would appear the wrong size bearings may have been used. Did your mechanic use plasti-gae to confirm what size bearing were needed? A newly reground crank with proper bearings and lube should be able to have been rotated.

Good luck and I hope this may have assisted,
