Replacement Oil Thermostat Sensor Sealing Washer for the Grom
About quality and texture: I am happy with the quality of the oil bolt washer from Honda, the washer is made from aluminium with an internal diameter of 10.2mm and external diameter of 15mm.
About the feeling of use: The original sealing washer had been reused once and now had a minor oil leak, the replacement sealing washer is a perfect fit for the port on the cylinder.
Products to buy together: The cam chain guide roller sealing washer in the cylinder would also be desirable to purchase alongside the oil bolt washer to ensure zero oil leaks after replacing the cylinder and having to transfer over these parts.
Difficulty of installation: The process to install takes about 5 minutes. First remove the electrical connector from the oil thermostat sensor and the remove the sensor, install the new sealing washer and torquing down the sensor to 15Nm. Not difficult to do.
Cost performance and comparison with other products: Good costing as you are getting a genuine Honda part made from a quality material at a great price.
About shipping and packaging: Sea freight was my preferred method of shipping due to the lower cost but currently unavailable due to Japan Post. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged.
Any concerns, cautions, or advice when purchasing: The Webike OEM parts section will be most helpful for sourcing other parts needed for your repairs.
