Bearing oil clearance and new size bearing

Greetings all. I need a little help. A couple months ago I spun a bearing on my car. I took the car apart to get to the oil pan and removed it. I discovered Rod #3 had spun. It scored up the crank pretty bad. So I did a little research online and decided to repair the crank in the car by using 400 Grit wet Sandpaper and a thick rope and wrap it around the crank three times and use a back and forth motion. It has taken me three days to get the crank to a mirror shine. It does still have tiny blemishes, but it it VERY smooth! Question #1. Should I remove even more even with tiny blemishes? Second issue. I bought standard size aftermarket rod bearings to replace the damaged bearings. However, after removing the material off the crankshaft it has left a larger oil clearance and the rod will again knock as before. I did plastigage the rod to crank with the new standard size bearing and had to move to a larger plastigage as the plastiage hardly compressed. I'm guessing the clearance is about .152mm. The Service Manual says the clearance should be .022-.046mm. I assume that would be for each bearing, correct? So, would that make it .044-.092mm? Still out of spec though. Question #2: What would be your recommendation is a bearing size then? I'm a little confused by the whole thing and need guidance. There is no way I could have removed that much material to throw it off that bad.

    If I did my math correctly, I would need two .03mm oversized bearings if my actual clearance is in fact .152mm and max spec for the bearing is .092mm. I cant seem to find bigger bearings to get the spec in the middle.

Is the shaft a perfect shape, if a bit out, it will fail straight away as the hardened coating is now missing. Use Engineers Blue and check the shaft.

Not sure this will work. Wondering if you could cut off your batteries and plug them back in again? It might do the reset on the CD as well since I know that the clock does get reset back to 12:00 or so.. All the best.

The problem is probably not the throwout bearing. Noise from throwout bearings act just the opposite, you only hear them when you push in the clutch pedal. Noise when the clutch pedal is released only is either a bad pilot bearing (probably oilite bushing) (the bearing/bushing in the middle of the flywheel that supports the transmission input shaft), or bad transmission bearings (will happen sometimes but is unlikely because in neutral, with the clutch pedal released, tranny bearings spin, but are not really under any load, but in some cases they might be the cause of the noise anyway)

SOURCE: How hard is it to replace the oil pan in an '04 Acura TL?

As to how hard it is to replace that depends. If you can remove the oil pan without removing any other parts then it is a simple repair. But if you must remove other parts in order to remove the pan it can be more difficult. Crawl under the car and see what must be removed in order to get the pan off. If you can buy a new oil pan for $95 then by all means buy it and replace it yourself or hire a trusted mechanic to do it for you. I can assure you it will not cost $300. At least find out what it will cost if done by someone other than the dealer. Honda's are reliable cars but their oil pan drain plugs are not. The problem is Honda uses an aluminum drain plug washer and this requires you to torque it to 29 ft/lbs in order for it to seal properly. Over time this will cause the pan threads, which are weak, to distort and eventually end up stripping out. The solution when you install your new oil pan is to not use an aluminum washer and instead use a fiber washer. If you pay someone else to change your oil, be sure and tell them to leave the fiber washer in place and not to install an aluminum washer. You then torque it to 15 ft/lbs and never have a leak or stripped threads. Another alternative is to just replace the drain plug with an inexpensive rubber drain plug you can purchase at any auto parts store. It will seal the drain and you just throw it away and install a new one at every oil change.

SOURCE: Clearance to remove 93 Acura Legend starter

you can either remove driver's side halfshaft or battery tray and alternator to remove the starter. i chose the halfshaft, since it gave a little more room to unbolt the starter. no need to drain transaxle when removing driver's side halfshaft. unbolt balljoint and tierod end from knuckle. i also removed the pinch bold that attaches the strut to the knuckle to allow more movement to remove the axle. axle nut is 36mm. use a large screwdriver or small prybar to gently pry the halfshaft from the transaxle, be careful not to damage the seal. upper bolt on the starter is really tough to get access to...

I dont know wich bearing to get for my 2002 chevy impala 3.8l v6. Some are standard, some 0.0010, 0.0020, 0.0030 ??

You want to have approximately 0.001-inch of bearing clearance for every inch of journal diameter. So for a 2.100-inch rod journal, it’s always a good idea to shoot for 0.0021 or 0.0022 bearing clearance.Too little bearing clearance can mean a spun bearing, we always aim to wind up too high rather than too low.

If the crank has not been turned and is stock with no wear I would go with standard bearings. With wear you may be able to do the .0010 over. If the crank has been resurfaced then I would suggest measuring the diameter with a caliper or request the resurface specs from the machine shop.

To be completely safe I would measure the diameter of the crank. You may be able to rent the tool from Autozone or Orielly's Auto.

Bearing oil clearance and new size bearing

No the oil clearance is correct for BOTH bearings @ .022 -.046 mm to try to get a true clearance measurement use a micrometer and measure in 4 places 90 degrees part this will check for out of round journal and compare to a factory journal size. there may be a .001 thousand or .002 thousand undersize bearing insert that will bring oil clearance in to specs. but most connecting rods get black from a spun bearing and they need to stay round so a inside micrometer is used to check that 10 times out 10 the connecting rod is replaced.

MOTOR KNOCKS, RED LINED it .1990 trooper 2.8 v6 whats the knocking coming form

If you red-lined it the most likely cause of a knocking noise is a spun bearing on the crankshaft. That means that a bearing has turned inside the bearing cap and is now restricting the oil flow. This will ruin your engine fairly quickly. The bottom end needs to come apart and the longer you drive it the worse it will get. Hope this helps.

Im trying to put new connecting rod berrings in my 1984 f 150 300 stright six i have my oil pan off but im not sure how to do this type of job do you have any suggestions

fist of all r u putting in mains too u should replace them all at once. to start u need a good torque wrench and some plastigauge and a book with all ur specs. u can get it at most parts stores. ok take the cap off of one and using a small block or wood or a mallat. not a hammer. knock the cap off and the connecting rod up about a half inch. clean good and put the new bearing in. no oil should get on the back of the bearing. a little assembly grease on the inside of the bearing. ok take ur plastigauge and put a new bearing in dry on both top and bottom. use a small piece of the plastigauge and put it on the bearing and torque it down, then take it apart and messure how much it smashed it out. that tells u the clearance. if its in spec then u carfully take the smashed plastic out and grease it good and put in back in and torque it down. do the same for all the rest. if you have a plastigauge showing too much clearance u may still be ok if its realy close but if its mor then 3 to 5 past spec u need a new crank, or have it turned down. remember most specs list new and max. dont go over the max because with new bearing just think how much u had with the old ones

Well the cam bearings will have to do with this also,if it has them,if not it can be the wear in the cam carriers.But most likely the crankshaft journals are worn to much,the crank would need turning,and over size rod,and main bearings would need to be installed.

2002 Mazda Protege 5 knocking engine

Uhh there are no rods in the head. That dealer has a loose rod in his head maybe.
The crank, rods and pistons are all in the bottom end of the engine.
What it likely is is either a broken piston skirt or a spun rod bearing.
Spun crank bearings are rare and sound deep.
A spun rod bearing can be fairly quiet on idle depending how bad it is worn out, but it will be really loud on acceleration. Piston slap from a broken skirt can be pretty loud too but it mostly sounds like diesel rattle only a bit less. Some have described it as a loud pinging sound like detonation.
Drain the oil and check for metal debri. If you can tilt the vehicle a bit for the oil to drain more towards the drain hole that could help. Then look for metal pieces and judge their size. There should be NO glitter whatsoever in engine oil, or any kind of debri. Now a rear end or transmission is different. Those always have a little metalic sheen to them.
Best of luck.

You probably spun a bearing. My wifes 2000 ford mustang did the same thing she never checked the oil and she said the oil light would come on briefly and oil empty filled back and knocking during acceleration and idle tore apart motor and there were three spun bearings.
