Product Questions
Frequently Asked Questions
What is the Caterpillar Oil Cap Screw 8S9092?
The 8S9092 is an oil-related cap screw (also known as an oil gallery plug or fastener) used in Caterpillar engines to seal or secure oil passages, covers, or components in the lubrication system. It plays a critical role in maintaining oil pressure and preventing leaks.
What engines or applications use the 8S9092 cap screw?
This cap screw is used across various Caterpillar engine assemblies. Check your service manual for the exact application or reach out to Propel Parts for help verifying fitment.
What are signs the oil cap screw needs replacement?
Look for:
- Oil leaking from the cap screw location
- Damaged or cross-threaded threads
- Corrosion or damaged sealing washer if equipped
- Loss of engine oil pressure in severe cases
A failed oil passage plug can cause significant oil loss and engine damage if not addressed promptly.
Does the 8S9092 cap screw include a sealing washer?
Some oil cap screws are designed to be used with a copper or aluminum sealing washer. Check your service manual to confirm whether a sealing washer is required for your application, and replace it with every removal.
Is the 8S9092 a high-quality aftermarket part?
Yes. Propel Parts offers the 8S9092 as a premium aftermarket oil cap screw that meets or exceeds OEM specifications for thread pitch, hardness, and sealing performance in Caterpillar engine lubrication systems.
Find related engine lubrication components in our engine parts catalog for Caterpillar equipment.
What torque specification should I use for the 8S9092?
Refer to your Caterpillar engine service manual for the correct torque value. Oil passage plugs require careful torquing — over-torquing can strip the threads or crack the surrounding casting, while under-torquing risks oil leaks.
Should I use thread sealant with the 8S9092 cap screw?
This depends on the application. Some oil passage plugs use sealing washers only, while others may call for a thread sealant. Always follow your service manual's recommendation — and never use PTFE tape on threaded oil plugs as it can break off and contaminate the lubrication system.
