1179137010 Toyota WASHER, CRANKSHAFT THRUST, UPPER, Price: 12.30$, Weight: 0.015kg

Upper crank thrust washer for Toyota engines ⚙️

This precision thrust element controls crankshaft endplay and protects the block from axial wear. Mounted at the upper side of the center main, it works with the lower half to keep the crank located front-to-back, ensuring smooth gear, chain, and clutch/torque converter alignment. Crafted from steel-backed, anti-friction material, it keeps a stable oil film for long life and quiet running.

Why this part is needed 🛠️

Without a healthy thrust surface, the crank can “walk” under clutch or converter loads. Proper endplay safeguards bearings, maintains seal integrity, and preserves timing accuracy. It also reduces heat and friction, boosting engine longevity.

How it works 🔧

Two thrust faces ride against the crank’s flanges. Pressurized oil and grooves create a hydrodynamic film that centers the crank axially. The result: controlled movement, smooth shifting, and steady idle with accessories engaged.

What happens if it’s worn or broken ❗

• Excess endplay, metallic scrape when pressing the clutch
• Hard shifting or clutch engagement changes (MT); pump noise (AT)
• Crank “walk,” timing variance, stalling or misfire at idle
• Rear main seal leaks; glitter in oil; rapid crank/block damage

Fitment and install tips ✅

Always replace as an upper/lower pair. Clean saddles, pre-lube, and orient oil grooves correctly. Torque main cap to spec and measure endplay with a dial indicator per service manual. If endplay is out of spec, inspect the crank thrust faces before running the engine. Fresh oil after installation is recommended. 🚗
