Civic timing belt deflection
I need some expert advice please. My 95 Civic EX had the timing belt
replaced by Honda almost 80,000 miles ago. I am worried about the timing belt tensioner going south because it was not replaced and now has 193,000 miles on it. The engine is making a little unusal noise which I have pinned down to coming from inside the timing belt cover. The water pump was also replaced about 6 years ago along with the belt and cam seals. I'm part way into the disassembly process and have found a rather loose timing belt. I can move the belt back and forth over an inch with just the upper timing cover removed. Is it normal for a Honda timing belt to have this much deflection with 80,000 miles on it. I plan on replacing everything this time. I have replaced around 6 timing belts but have never done a Honda. Thanks in advance for any info or assistance. |

I heard that a new belt should have about 1/2'' deflection, so 1'' at 80,000 doesn't seem surprising. |

Thanks in advance for any info or assistance. > count yourself lucky the belt never skipped! it was set wrong. belts don't stretch. but the helm workshop manual and follow to the letter the belt tensioning procedure, and everything will be peachy. maybe practice a couple of times before doing it "for real". regarding the tensioner, replacement is probably a good thing. same for the coolant pump. i personally wouldn't bother with seals unless they're leaking, and even then if they were leaking, i'd change to a seal-friendly oil before changing them. scratching the sealing surface of the cam or crank with a seal puller ruins the seal's ability to do its job and seriously reduces seal life. |

Thanks in advance for any info or assistance. ----------------------------- As was said, they don't really stretch, so the last installer forgot to turn the engine over a few times to 'center' the belt, or forgot to take up the slack in the belt a bit by turning the cam in the direction of the tensioner before locking the tension. An inch isn't a huge deflection (depending on where it is, of course). Don't go too tight or it will sing annoyingly . . . Look at tegger.com for a bunch of tips about changing the TB.

Civic timing belt deflection
Thanks for the inputs Jim, Curley and Alan. After removing the bottom
cover, I discoverd at least a 1.5" deflection. I think the noise I heard was the belt being so loose. I have just finished marking the old belt to the pullies. It looks new inside and out so far. The tensioner feels smooth. I'm ready to remove the belt and spin the water pump. The belt, water pump, and oil seals were replaced excatly 7 years and 77,250 miles ago. But, not the tensioner according to my Honda dealership paperwork. I noticed a proceedure to adjust belt tension in my factory maint book by removing a plug and the top timing cover which is a piece of cake. This makes me wonder if it might be a good idea to check belt tension at 45,000 miles. Do these belts ever stretch or not? Of course I will change everything except the oil seals. The seal area looks totally dry. The belt is so old and all that flapping around could have not been good for it. I'm sure glad it did not skip! Cheers. |
