description

This main bearing set is a complete overhaul kit for heavy-duty 3406E and C15 engines. It contains all main shells and thrust shell in one package. Anti-friction alloy lining bonded to steel backing with oil retention grooves maintains stable oil film. It bears heavy radial load and restricts crank end play. All shells are sorted in one batch with consistent tolerance. Widely fitted on 621K scraper, 374D, 375 excavators, 730, 740 articulated trucks and large generator sets for mining heavy-duty overhaul.

Advantages

1. Pre-packaged full set with all main shells and thrust shell, simplifies purchasing and site installation.
2. Batch sorted for unified tolerance to keep balanced radial and axial clearance after assembly.
3. Anti-seizure alloy lining delivers reliable wear resistance for continuous impact mining load.
4. Even oil distribution from honed grooves maintains stable oil film and reduces bearing seizure risk.
5. Tight flatness control on shell back prevents bearing rotation and shifting.
6. OE dimension matches C15 / 3406E crank journals precisely and reduces assembly errors.

FAQ 

Q1: Is 199-2164 oversize or standard bearing set?
A1: This is STD standard set. Select matching oversize kit for reground crankshaft journals.
Q2: Can I split the set and use only the thrust shell separately?
A2: Splitting is not recommended. Shells are sorted as one set, separate use will cause unbalanced clearance.
Q3: Can shims be added if end play is too big after installation?
A3: No. Check crank thrust surface wear instead of adding shims for compensation.
Q4: How to store the whole bearing set?
A4: Keep in original package, do not split. Protect alloy surfaces and store in dry anti-rust environment.
