Do you have a manual? You'll need one to cross reference those codes. The 5 digit codes on case and crank are for main bearings. The "L" just means they read left to right. Codes for your mains are (from left to right with motor in upright position)...B2, A2, B2, C3, B2. Let me look and see if I can find a manual online. The 4 digit codes are for your rod bearings. You match them with codes on rods and get your final code for that bearing.

Okay, just downloaded manual for the 929 (gotta love the internet LOL). Your main bearing colors are (left to right)....Yellow, Pink, Yellow, Brown, Yellow. If you'll post the numbers off your rods, I can tell you what colors you need for rod bearings. I always plastigage rod bearings, especially with a used crank. It takes a lil more time but it's worth the peace of mind. Oil clearance for rod bearings is .0012-.0020

Codes on the rods are in numbers. Should be either a 1,2, or 3. There may be letters on there but ignore them, they are weight references and aren't important. Did you mark the rods 1 through 4 so you can put them in the right cylinders? If you haven't, do so before giving me the numbers off them. Then post them starting with rod #1. Then when you're ready to put them together, the bearings will be correct.
It is kinda confusing at first, but you get used to it LOL. Be sure and use new nuts on the rods when installing them and don't skip the plastigage step. If you've never used it, it comes in different sizes so be sure and get the one that covers oil clearance specs I posted. Rotate crank til rod journal you're measuring is closest to you. Then carefully pull rod up and seat it on journal. Then lay small strip of plastigage across journal. Then install cap and torque to specs. Make sure you hold rod perfectly still while torquing or it won't show true measurement. After torquing, remove rod cap and hold package up to plastigage til line on package matches thickness of plastigage on journal then read the clearance. Bearings have to be perfectly dry also.
Get back to me with those rod numbers and I'll look it up. I have manual saved on my pc at work and I'll get them tonight.

Are those readings starting with cylinder #1? If they are, your rod bearing colors are (from 1-4) Brown, Brown, Black, Brown. Plastigage is this thin spaghetti noodle looking stuff. You can get it around here at most auto parts stores. You break off a small piece and lay it across crank journal. Then you install rod (with dry bearings) and torque to spec. When you torque it, it mashes the plastigage. On the package plastigage came in there is a scale with different widths on it. You compare the scale with the plastigage material on your journal and it tells you the clearance. Just google it, I'm sure there are better explanations out there than mine LOL. It's really easy to get parts mixed up or figure up wrong color so it's just extra insurance that you did the job right. Oil clearance isn't something you want to get wrong, trust me. Also you need a good manual. Go to www.rrzone.com and click on their "downloads" section. There is a 929 factory manual download there and it's free. If you have trouble finding it, just register and ask a member.
