Replaced Timing Belt but . . .
Am now wondering what all the fuss was about.
To backtrack, I have been reading this newsgroup off and on for the last few years. I've seen many posts here warning of the importance of changing your Honda Accord's timing belt at 75,000 miles or 7 years (or whatever the interval is) or dire consequences will occur. Long story short, I delayed replacing it for well beyond this replacement interval but finally replaced both the timing belt and water pump on my 1994 Honda Accord with 98,000 miles on it. I am the original owner and the timing belt had never been replaced before. I told the shop to keep the old parts so I could see what they looked like, expecting their condition to be terrible based on posts I have read here. When I picked up the vehicle, they had placed the old timing belt and water pump in a plastic bag for me. The timing belt was a small all-rubber belt with teeth on it which went all the way around. I carefully inspected this 13 year old timing belt and it looked almost brand new! No cuts, nicks, gouges, discoloration or any other noticeable wear! It looked fine, like it didn't really need to be replaced. Not at all what I expected it to look like. I'm not saying I wish I didn't have it replaced. It gives me peace of mind to have done so and if you guys say it's important, well you know alot more about this stuff than I do. Just saying it didn't look at all like it needed to be replaced. Is stretching of the belt over time, which I probably would not be able to notice, the issue affecting an old timing belt? Anyway, just not what I expected to see. |

The failure typically occurs where the teeth attach to the belt. On a new belt the teeth are firmly attached. By the time it's ready to be replaced the teeth can be picked off with a knife blade. I'd expect yours to be in that condition. By the time I replaced the belt on our old Volvo - a non-interference engine - at about 150K miles the teeth could be picked off with a thumbnail. Although the belt is often referred to as "breaking" I've never personally seen one fail that way. They don't stretch measureably. Timing chains are said to stretch, but as with bicycle chains it is really that the pivots wear and the slack makes the overall chain longer. That lack of visible change in the timing belt is why they are replaced on schedule rather than on visual inspection. There is no reliable visible warning of impending failure. Mike |

So is the fabric in the core of the timing belt surrounded by the rubber so that it cannot be seen? I still have the old timing belt, and when I inspect it carefully I cannot see fabric anywhere. I can see how the fabric would provide added strength. Maybe I'll disect it and see exactly how the fabric works. Thanks. |

The fabric helps to minimize elongation of the belt while, as I believe the fabric is actually highly drawn fibers or monofilaments with high tensile and minimal elongation properties. Embedding these in the belt cross section adds strength and minimizes the elongation while not affecting the "suppleness" (it's ability to bend around a specific radius without buckling or bulging). |

Unlike shipping tape you use for packing boxes, which can stretch or break, strapping tape will hold a TON of load before breaking. You can _clearly see_ the fibers in the side view of the timing belt. The usual area of failure on a TB is when the teeth shear off because the fibreglass threads have finally lost their strength. 'Inspecting' a Timing Belt is usually a waste of time unless the idler has seized and the backside of the belt will show chafing, or there's leakage problems and the belt is soaked with coolant or oil..
