| Post subject: | Balance Shaft Belt Overtension 99 GSX |
I have a 99 eclipse gsx. I did a timing job on the car like 15k ago with all new OEM components and belts. Well I started to get a vibration and then my water pump went out on me. So it was time to do something about it. I went to pull the water pump and come to find out the OEM balance shaft belt (15k miles) was ate up. The balance shaft belts teeth were all gone and torn up inside the timing cover. The belt was just the ribbon core that was still spinning the balance shaft. The debris made me skip a few exhaust teeth but got lucky and didn't skip any intake. Moving forward. I have done many timing jobs, but come to realize I don't really have balance shaft in my cars nor do I own a 7bolt besides this gsx. Well the 99 GSX does have its balance shafts being that it is bone stock for the most part. So when installing a gate balance shaft belts I notice the belt was pretty tight without a tensioner. When I put the tensioner on I had to pull up on the belt to get it to fit. I didn't even have to pull or move the balance shaft tensioner to have "proper" tension. This makes me worried something is wrong. I am freaking out that this might make me skip a intake tooth. I drive over 500 miles a week and my 175k GSX is my daily. Let me know what you guys think and if any of you have ran into this issue. I also checked to make sure the new balance shaft tensioner pulley was the correct one. I had a dayco and a gates. I normally order oem but didnt have time. I couldn't tell a difference in the gates and dayco so I don't know which is on the car. PLEASE HELP I didn't see a thread out there with a issue of over tightening with out moving the BS pulley so if I missed something on one of the other forums or on this one I apologize. I am only a member of this forum, fyi |

where did you buy the belts from? I put what they called oem timing belt on my car a few years ago.. (bought from autozone)..and it broke after 7k miles.. so from now on I wont trust anything but gates belts.. just cause they say oem..doesnt mean there gonna last..sad but true. Steve |

I meant a belt from Extremepsi.com and it was sent with a MITS label and Part number for everything. All my components and belts were like that. It cost me like 250 for parts. |

The balance shaft belt shouldn't be that tight. On the cars I've done the belt was easy to get on and I had to rotate the tensioner pulley quite a bit to put tension on it. |

Well I don't get it then. My car is stock. I have a 7/6 bolt balance shaft belt. I have a 7 bolt tensioner. I even compared it with the 6 bolt. I should have tried the 6 bolt tensioner and seen what it was like. I am stumped. I am just babying my car. |

Hows the car running? Why not just eliminate the balance shaft? I eliminate mine during the build, one less thing to worry about |

It has 179k on the block and seems to be running fine so far. I am not pulling the motor to remove the balance shafts. I have a newer motor to go into the car now that I will do a balance shaft delete on when I get there. |

Car is running fine but I still don't know how the balance shaft is acting. I hope in the next couple weekend to take the timing cover off and see how everything is holding up. |

FYI: Belt tension should be 5-7 mm (.20-.28 in.) using the belt deflection method. Info pulled from: http://vfaq.com/mods/timingbelt-2G.html |

^^^ Just did this myself. Kinda crappy that you have to measure or suppose you got 5-7 mm with proper finger tension applied.
