CONSTRUCTION
A roller chain sub-assembly with a 9.525 mm (0.375 in.) pitch is used.
The chain sub-assembly is lubricated by a timing chain oil jet.
The No. 1 chain tensioner assembly uses a spring and oil pressure to maintain proper chain tension at all times. The chain tensioner suppresses noise generated by the chain sub-assembly.
The No. 1 chain tensioner assembly is ratchet type with a non-return mechanism.
To achieve excellent serviceability, the No. 1 chain tensioner assembly is constructed so that it can be removed and installed from the outside of the timing chain or belt cover sub-assembly.
