Engine oil seal kit for many of the 50-70cc Honda's. This kit is made up of high quality new seals produced in Taiwan of China. When it comes to rubber parts and seals it's generally better to install a brand new part instead of using a NOS part which has hardened due to age. Make sure to press your seals in straight with a seal driver or a socket with a slightly smaller OD than the seal. Both surfaces must be free of dirt in order to form an oil tight seal. Many of these seals were also used on other models, if you have a 50-70cc Honda it uses a few of these seals.
