SOURCE: I am considering replacing the entire crank assembly. any tips?

You will need a flywheel puller you can purchase from denniskirk.com or other mc tool outlet. This is a must tool. Otherwise you can do the job with simple hand tools such as wrenches, allen wrenches all metric of course, and a rubber mallet. It will take about two hours to disassemble. your crank will have to be rebuilt by a shop with a crank jig and a press. the halves must be aligned perfectly. then wash everything very good make sure you have all the exploded bearing cleaned out then make sure again, and reassemble. best wishes!

SOURCE: need to replace lower connecting rod bearing,

To replace just the lower connecting rod bearing is difficult. It needs to be pressed, and then trued to specs. If this is not done correctly, your crank will destroy itself very quickly. Buy a crank, and replace the bearings and seals on the left and right of it.

I did NOT get the help I needed nor will I be using your site again. I feel like it was a total waste of my time and money. I would love a refund of my money but know my time is lost forever.

Understand that your bike has a pressed crank. A shop will need to press the crank apart then press it back together and align the crank. I suggest you go to Babbitt's for parts.

New crank main bearings are highly recommended.

Was told that my lower end is junk. Seams fine to me but not sure on how to check with out splitting the Case. Is there any little tips or tricks. The rod has alittle side to side play but not...


Hi, spin the engine, with the piston removed hold onto the top of the con rod and start to turn it keep spining it and listen how quiet and smooth it is, the main bearings when worn will sound noisy and feel rough, the big end may lock up when worn,bring the con rod to the top, in the middle of the big end where the pin holds it to the crankshaft, you will see a cut through the rod where the bearing is visible inspect the bearing for condition, the bearings are held in a cage which when worn breaks and the rolers become loose, this may cause the bearing to lock, also check for up and down movement, at all parts of the stroke

My bikes engines one piston is not working.it broke the connecting rod which damage the cylinder and the engine.what can i do of the broken connecting rod.


You would need to replace the rod $70 and needle bearing $30. Both appear to be avaiable at Babbitt's. A dealer would need to tear down the engine all the way then use a hydraulic press to press apart the crankshaft and then mount the new connecting rod and press the shaft back together. Dial gages must be used to get a correct centerline on the crank.

The total cost will likely be $1000 if a dealer does the repair from start to finish. Please rate my answer. Thanks.

Lower connecting rod bearing in my cr 125 1998


Probably $900 at the shop. Price it out at a few shops. The entire engine gets torn down. Be sure to install new crankshaft end bearings and seals as well as shift shaft seal and sprocket outer bearing and seal. A flywheel puller, impact driver, case splitter and torque wrench will be needed. Sorry for the pain.

Could you take a moment and rate my answer? Thanks!

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.

RM 250 Clutch noise 1986 (Yes an old girl I know)


The clutch has two different types of needle bearings. One flat thrust bearing about 1" diameter and one caged needle bearing. The most likely culprit is the thrust bearing. This is a 5 to 10 dollar bearing and easy to replace if you have an impact driver to loosen the right case cover screws. Drain the oil, remove the right case cover then the clutch end plate. The bearing is there, and will probably come off with the plate.
