Parts for your 2002 Honda Stream-Thrust bearing

2002 Honda Stream thrust-bearing — what it is and how to look after it

Based on Honda factory service information for the RN1–RN5 Stream (2001–2005) and OEM parts catalogues for the D17A and K20A engines, a thrust-bearing is absolutely used on the 2002 Honda Stream. The engine’s main bearing set includes thrust faces to control crankshaft end-float, and manual-transmission models also run a clutch release (often called “thrust”) bearing. Automatic/CVT variants use internal thrust bearings/washers within the gearbox, but these aren’t routine service items.

What does it do? The engine’s thrust-bearing keeps the crankshaft centred fore-and-aft, coping with loads from clutch engagement (manual) or converter/pump loads (auto). Without it, the crank can “walk”, chewing out bearings, upsetting oil clearances, and playing havoc with the rear main seal. On manual models, the clutch release bearing lets the pressure plate be disengaged smoothly when the pedal’s pressed, preventing heat and friction at the diaphragm fingers.

Is it a maintenance item? Not really. The engine thrust-bearing lives in the bottom end and is inspected/renewed during a rebuild or when significant end-float is suspected. A quick workshop check is to measure crank end-play with a dial gauge, if it’s outside the spec in the Honda manual, the bearing set (including the thrust faces) should be replaced and clearances verified. Keep oil changes on schedule and use the correct viscosity — clean, well-pressurised oil is the thrust-bearing’s best mate.

For manual Streams, the clutch release bearing is replaced whenever the clutch is done. If there’s a whirring or growling that changes when the pedal is pressed, or a gritty feel in the pedal, budget for a full clutch kit (disc, pressure plate, release bearing) plus guide/throw-out surfaces inspection. It’s a gearbox-out job, so doing the lot once saves labour and headaches.

Auto/CVT models don’t have a user-serviceable external thrust-bearing. If there’s end-float noise or metal in the fluid, that’s a transmission-rebuild conversation with a specialist rather than a driveway fix.

• Tell-tales of engine thrust wear: clutch pedal changes idle, metallic scuff from the front/rear of the block, or visible pulley movement with pedal input.
• Tell-tales of release bearing wear (manual): noise that appears/disappears with the pedal, rough engagement, or vibration through the pedal.

Use quality OEM or equivalent bearings, follow the Honda torque/clearance specs, and get the flywheel and pressure plate surfaces checked so everything runs sweet for the next 100,000+ kilometres.

FAQs

Does a 2002 Honda Stream have a thrust-bearing?
Yes. The engine uses thrust surfaces in the main bearing set to control crankshaft end-float. Manual models also use a clutch release (thrust) bearing, auto/CVT models have internal gearbox thrust bearings that aren’t routine service items.

What are the symptoms of a worn thrust-bearing on a Honda Stream?
Engine thrust issues can show up as end-float noises, shifting idle when the clutch is pressed, or visible crank pulley movement. A noisy clutch release bearing will whirr or growl and change with pedal position, often feeling rough through the pedal.

Should the thrust-bearing be replaced as regular maintenance?
No. The engine thrust-bearing is inspected during bottom-end work or when end-float is out of spec. The clutch release bearing is best replaced whenever the clutch is renewed since the gearbox is already out.
