Talk:Timing belt

From Wikipedia, the free encyclopedia

I restore the inline external links because they are "references". I don't like commercial links in Wikipedia anymore than than the next person, but the article contains non-obvious facts (Kevlar, 1945, etc) and references should be cited. If you have better references for those facts, we can replace the commercial links. Samw 00:57, 13 May 2005 (UTC)

[edit] Question:

Is it true that not all cars, e.g. Ford Fiesta Encore, have a cambelt? If so, how is this so? Gwaka Lumpa 12:21, 30 April 2007 (UTC)

The 1.3 Endura-E engine used in the Mk. IV Fiesta is an OHV or "pushrod" engine which just has a small timing chain, and is not considered a part that requires servicing (there were several other engines in the Fiesta too). I'm not sure if this is the case with all pushrod engines, or if they're still interference engines or not - I think this needs to be clarified in the article. --Zilog Jones 16:09, 8 October 2007 (UTC)

[edit] Question: Timing belt Alternative for bicycle

Timing belts "never became popular" as a bicycle chain alternative. Why? Is the timing belt less efficient than the bicycle chain? Why is it popular in cars? Is the timing belt more efficient, or does it have a longer life, or is it cheaper to produce, or does it have less wear on the cam?
