The 0.299 seal from Chen Ming is the latest innovation in sealing technology, designed to keep fluids out and debris from entering the motor. With two lips to keep the fluid out and one excluder lip to keep debris at bay, this seal is a game-changer in the industry.
However, there is an alternative seal available that is made from fluoro rubber and designed to be lubricated with grease or oil. The question arises – will this seal work better or worse than the Chen Ming seal, especially when only coolant is available for lubrication?
The blog writer decides to start with the Chen Ming seal and see what happens. The process of mounting the seal proves to be a challenge, with the protective sleeve not fitting the shaft properly. After some trial and error, the seal is finally mounted, but not without some damage due to improper handling.
To prevent further damage, the writer suggests prepping the seal by expanding the diameter of the excluder lip before mounting it on the shaft. This makes the mounting process much easier and reduces the risk of damaging the seal.
The writer also delves into the importance of surface roughness for Teflon seals, using sandpaper to achieve the ideal roughness for a proper seal. After polishing the shaft, the writer measures the thickness of the seal and notes some wear on the lip where it touched the shaft.
Despite some wear, the seal proves to be tight and effective, with Permatex Ultra black used to ensure a leak-proof seal between the seal and the manifolds. The mounting process may require some force, but the end result is a secure and reliable seal.
In conclusion, the 0.299 seal from Chen Ming is a durable and effective option for sealing applications. While there may be some wear over time, proper maintenance and installation techniques can ensure a long-lasting seal. For those looking for a reliable replacement seal, the writer welcomes suggestions and feedback from readers in the comments section.
