Timing Chain vs. Belt

Discussion in 'General Motoring' started by Steve Giannoni, Jun 3, 2011.

  1. So what fraction of chains are driven by a polymeric or nylon gears.
    Is changing the driving gear part of the specified maintenance ?

    Nothing very specific on that floating around. Some metal gears have
    nylon teeth which make them cheaper and easier to produce. Years ago,
    I had a 1988 Olds Cutlas wagon with a plastic gear. It shredded as I
    started it up to leave work. Luckily the car wasn't in motion. I
    turned off the engine right away. And had no chain slap damage. Some
    are all nylon. I don't really care much about engine noise. So I told
    the mechanic to put an all metal gear for the chain.

    I just had the timing belt and water pump changed on my 97 CRV, a few
    months ago.
