I've recently purchased my first Harley.....a vrod with transmission trouble. I've successfully removed the engine, split the cases, and diagnosed the tranny issue. Now I'd like to replace the main and rod bearings. I pulled the bearing shells out of the lower case and found the part # 24313-01k which I cant find anywhere. Have any of you had this issue? or Do any of you guys have access to a new/old part number reference?

What year is your bike?

VRSC crankshaft bearing info is stamped on the crankshaft counter weight. There should be a color code stamp starting with ALT followed by four color code stamps, e.g., ALT G RR G. The first letter after ALT is the alternator side main bearing color code, the second letter is the front rod bearing color code, the third letter is the rear rod bearing color code, and the fourth letter is the clutch side main bearing color code. What's your crankshaft stamp code?

The main bearings are available in three sizes:
B = Blue = 24411-01K,
G = Green = 24410-01K, and
R = Red = 24409-01K.

The rod bearings are available in 2 sizes:
R = Red = 24412-01K and
B = Blue = 24413-01K.

This is for all VRSC engines 2002 to present. There's also some thrust bearings for the crankshaft (24312-01K) but P/N 24313-01K is not a valid VRSC P/N.

Thanks for the info. I did read about the stamp behind the alternator on the webbing in my service manual but was trying to leave the crank as undisturbed as possible. I guess I have to change that approach and turn or lift the crank as needed.

Oh and I checked the Rod bearings. The part number stamped on them are 24314-01k. These have to be oem part numbers that are invalid now.

I've read about some with the same part number on the bearing. Can't use that number as it does not exist for a parts listing. Dealer will never find it either. Go with what Steve posted regarding stamp and color code and the actual part numbers.

Thanks Ron. I checked the webbing on the crank. Had "ALT G RR G" stamped on the back. I had to turn the crank to get it into position. Probably should have done that to begin with. I'm a newbie what can I say Took a few minutes to figure out which way was counterclockwise with the engine being upside down. I didn't know if I was suppose to be facing the alternator side of the engine or the clutch side...lol.

Are thsoe sizes or thrust bearings for the crankshaft (24312-01K) but P/N 24313-01K is not a valid VRSC P/N.
