WHEN YOU REPLACE ROD BEARINGS YOU HAVE TO CHECK CRANKSHAFT JOURNALS WEAR.IF TAPER TOO MUCH.CRANKSHAFT HAS TO BE REGROUND OR REPLACE.YOU HAVE TO TAKE ENGINE OUT OF CAR.TO DO A SHORT OVERHAUL.YOU CAN REPLACE BEARINGS IN CAR USING ROLL OUT PINS AND DROP THE OIL PAN.BUT WHEN YOU REPLACING ROD BEARINGS AND MAINBEARINGS CRANKSHAFT HAS TO BE CHECK FOR WEAR.IF YOU PUT NEW ROD BEARINGS IN THEY WILL FAIL PREMATURELY.

SOURCE: changing rod bearings

You'll find that once you've removed the connecting rod cap, that you can easily replace that one of course, so take a small screwdriver and use it to push up on the other bearing, on the side that doesn't have the notch, you should be able to also push up a hair on the rod to get a little slack, but the bearing will slide around the crank and you just reinsert the smooth part first, kind of just the opposite of what you just did to reinstall. center the bearing in the rod, pull the rod flush with the crank and reinstall the lower cap and torque to specificatioin.

Of course, lots of oil on the bearings & crank, if there is damage to the crank, you may want to turn it enough with the cap & rod not on it to polish it a bit with emory cloth.

Clearance shouldn't be a factor but you must torque to the exact specs to get the correct "crush" on those bearings and provide proper contact, while not being too tight to cause immediate breakdown by not letting the oil pass & lubricate the crank.

Hope that sheds some light on it. Crank bearings can be changed the same way.

good luck.

To do that properly you will have to pull the motor out, remove crank, check to see if you need standard or oversized bearings and do all new gaskets.

Can I change the connecting rod bearings on a 1.8 2010 focus with no issues


If your connecting rod bearings are bad, you probably have some scoring on the surface of your crankshaft journals as well. If not, a simple replacement of the bearings should be a doable job for a mechanic.

Replace connecting rod bearing 5.3 litre Tahoe Z71


It is rather unusal to replace only one, but perhaps you mean they intend to replace all rod bearings. Even that is often not a good idea. Once a rod bearing has spun or failed, metal particles are al through the engine and the main bearings may be damaged as well. I hate trying to patch an engine in this fashion because it seldom gives satifactory results. You may wish to consider a short block engine replacement and have you existing heads reconditioned, or better still a crate engine of know specs which meets your usage needs. Sorry to be the bearer of bad news.

I have a 2004 civic making loud rattling noise when i start it or step on gas

I am told I have a connecting rod problem... can you tell me if this is a sign of something worse to come?


If you have a connecting rod problem then you have a serious problem. This is the rod that hooks the piston to the crankshaft. Get it looked at before you send a piston through the side of the engine. I will cost more to replace the entire engine. Most reputable mechanics can replace the rod, bearing, and related parts for a reasonable cost. Good luck, do it soon

1995 Isuzu 5500 box truck 6 cyl diesel. truck overheated and water&coolant ended up in the oil pan and the motor ended up locking down. Can only spin fly wheel 1/2 to 3/4 revolution besides changing...


The connecting rods are probably frozen to the crank from overheating or the bearings are frozen. Pull the oil pan off and inspect the connecting rod bearings for a blueish coloring which is a sign they overheated. If they are you'll need to replace them all and have the crank and connecting rods turned.

How to replace the piston connecting rod on a 1993 chevrolet corsica 3.1L?


If you need to replace a rod, generally you have a bearing problem that requires crankshaft removal/replacement as well. If you have a bad wrist-pin on the small end of the rod or the rod bent from hydro-lock and bearings are good, you need to remove the oil pan and the cylinder head as the piston/rod assembly comes out from the top.
If you have a spun bearing or broken rod, the entire engine needs to be removed, completely torn down and all passages flushed...far easier to replace engine with a good used one.
To do either, you will need a manual to guide you through the process (far too long to write out here) Sorry I need to tell you this but that's just the way it is...better you know before even attempting to do the job.

I'm looking for the 2000 isuzu rodeo 3.2L v6 connecting rod bearings torque specs.


1. Check the connecting rod alignment If either the bend or the twist exceeds the specified limit,the connecting rod must be replaced. Bend per 100 mm (3.937 inch) Limit: 0.15 (0.0059) Twist per 100 mm (3.937 inch) Limit: 0.20 (0.0078)

2. Measure the connecting rod thrust clearance. Use a feeler gauge to measure the thrust clearance at the large end of the connecting rod If the clearance exceeds the specified limit, the connecting rod must be replaced. Standard: 0.16 mm - 0.35 mm (0.0063 inch - 0.0138 inch) Limit: 0.40 mm (0.0157 inch)

3. Measure the oil clearance between the connecting rod and the crankshaft.

    1. Remove the connecting rod cap nuts and the rod caps (12). Arrange the removed rod caps in the cylinder number order.
    2. Clean the rod bearings and the crankshaft pins.
      1. Carefully check the rod bearings. If even one bearing is found to be damaged or badly worn, the entire bearing assembly must be replaced as a set. Reinstall the bearings in their original positions. Apply plastigage to the crank pin.
      2. Reinstall the rod caps (12) to their original positions. Tighten the rod cap nuts. Torque: 54 Nm (40 ft. lbs.) Note: Do not allow the crankshaft to rotate.
      3. Remove the rod caps.
        1. Measure the width of the plastigage and determine the oil clearance. If the oil clearance exceeds the limit, replace the rod bearing as a set. Standard: 0.019 mm - 0.043 mm (0.0007 inch - 0.0017 inch) Limit: 0.08 mm (0.003 inch)
        2. Clean the plastigage from the bearings and the crankshaft pins.

      • Stage 1: 25 Nm.
      • Stage 2: 60 degrees.
    1. Tighten the connecting rod bearing bolts in two stages.
