ACL 1T1957-STD Honda/Acura B/K-Series Thrust Washers

1T1957-STD Thrust Washers for Honda and Acura Engine Builds

ACL 1T1957-STD is a standard-size thrust washer set used across multiple cataloged Honda and Acura engine families. Confirm the exact engine code, crankshaft version, journal dimensions, bearing position, and assembled clearances before ordering.

Key Features

• Standard-size thrust components for cataloged ACL main-bearing applications
• Used with selected B-series, D-series, F/H-series, and K-series bearing families
• Two-piece thrust washer set
• Application-specific thickness and diameter
• ACL 1T1957-STD must be selected by exact engine and measured dimensions

Fitment

Vehicle year and model alone do not confirm compatibility. Engine swaps, mixed blocks and crankshafts, and previously machined assemblies require direct dimensional verification.

Specifications

Whats Included

• One two-piece ACL thrust washer set
• Manufacturer packaging and identification for ACL 1T1957-STD
• Only the component identified in this listing is included unless the package contents state otherwise

Frequently Asked Questions

What is the 1T1957-STD?

It is an ACL thrust washer set for the cataloged Honda and Acura engine applications shown above.

Does vehicle year and model confirm fitment?

No. Verify the engine code, crankshaft, journal dimensions, and bearing position.

Must clearances be measured?

Yes. A qualified engine builder should measure every relevant journal, housing bore, and assembled clearance.

Can I substitute another size suffix?

No. Standard, repair-size, and extra-clearance suffixes identify different dimensional requirements.

Are the related bearings included?

No. Main bearings, rod bearings, and thrust washers are separate components unless the listing explicitly states otherwise.

Does one bearing family fit every K-series engine?

No. For example, some K20C applications use a different main-bearing family even when a rod-bearing family is shared.

Does this thrust washer fit every engine named in the existing vehicle tags?

No. Confirm the exact ACL main-bearing pairing and measured thrust dimensions for the engine being assembled.

Should a professional install these parts?

Yes. Precision engine-bearing installation should be completed or checked by an experienced engine builder.

Installation Instructions

1. Confirm ACL 1T1957-STD against the engine build sheet and measured requirements.
2. Verify the engine code, block, crankshaft, and bearing positions.
3. Measure journals and housing bores with calibrated tools.
4. Clean all mating surfaces, oil passages, and bearing components.
5. Check locating features, oil-hole alignment, fillet clearance, and component orientation.
6. Install and torque fasteners using the engine builders specified sequence and procedure.
7. Measure assembled clearances, endplay where applicable, and free rotation.
8. Apply approved assembly lubricant and prime the oiling system before startup.
