Finished rebuilding newly acquired 93 metro virt and embarked on an unsuccessfull 2h war reinstalling the old timing belt. I almost took out my gun on the sucker that wouldn't install because it's just too short and the available adjustments inadequate. Heating over a kerosene heater for 10 minutes did not help nor did smoldering the sucker on top of the kerosene heater. Please do not try to suggest sticking in the oven at 250 cause it won't work. Now I see why so many timing tensioners get ruined. Anyone ever tried unfastening the camshaft and tipping it to fit the timing belt followed by rebolting the camshaft down to stop the nightmare? Sure hope the new one I ordered is not going to give me the same problems. Edited by chessir, Oct 29 2013, 11:59 PM.

Remove the adjuster stud. That way, you can rotate the idler bearing further out of the way than the slot in the adjuster allows. Don't forget to tighten the bolt on the idler bearing. I use a drop of blue Loctite on the stud where it goes into the water pump. |

Thanx GG: I did that on previous and just did not think the idler would pull back far enough on this one but I'll give it a shot. |

The other thing you can do is loosen the idler bearing bolt just enough to allow it to disengage from the pin on the adjuster and roll it out of the way towards the rear of the car. Once the timing belt is in place, roll the idler bearing back into position on the pin and finger the bolt down so it doesn't disengage. Make sure the pin is properly engaged and that it moves when you move the adjuster. Of course, you'll need to leave the adjuster stud installed and in the full loose position for this trick to work. |

I had the same problem not too long ago. I had to slip a small portion of the belt onto the crank sprocket and the cam sprocket. Once it was barely on, I was able to hit it with a hammer to drive it home. Sounds crude, but it was effective. |

after the abuse that you put that old used t-belt thru, do you think that it is a good idea to run it? I sure don't! I would cosign with dayle1960, it is good to just start the edge all the way around, then work it on. rather than resorting to a hammer, I might suggest rolling the engine over by hand once the edge is started, just pushing it on as you go. if you want a good unmolested used t-belt, PM me I have plenty.

I can't figure out why you would go through all the trouble to install a used timing belt . . . . REALLY? Wouldn't a new timing belt be more pliable, and easier to install? Are you sure of how many miles are on the belt, and it's condition? You may find that you'll be doing this again sooner than you'd like. There's no way that I would waste my time installing a used timing belt. |

I've never really had an issue installing timing belts on Metro's until I used a Mark Dvorak head gasket. Both engines I used them on were very difficult to get the belt on. It's like the gasket was too thick. I had this issue before with a Subaru EJ25 engine, the ebay gaskets were too thick and wouldn't allow the belt to go on. I bought factory Subaru head gaskets and everything was fine after that. |

The trick is to make sure the oven is OFF after it's preheated to 200-250, and then it's placed on a cookie sheet, for only about 10 minutes. I would not use any other sort of oven than an electric or gas kitchen appliance. |

by any chance, did you do any compression test comparisons while running the MD head gasket vs the others? |

Wished I had, I'd like to know now. My twin cam motor doesn't feel as though it has as much torque as others I've driven, possibly from slightly lowered compression? |

I had the SAME trouble recently... Got the replacement belt at Napa..... Here's what happened.... There are TWO different belts used on several years.... One for the CAMI (C Vin) and one for the Japan (J Vin)... The one that comes up on the computer first is the Japan vin one... and it's about 1/8" too short and it WON'T GO no matter what you try to do..... It is used with the 5-bolt crank sprocket.... One thing I saw is that the Too Short one had ROUND teeth and the right one had SQUARE teeth.... They had to dig in the computer for a LONG time to figure out the right one.... Eventually got it... It fit exactly right. It goes with the 4-bolt crank sprocket... The belt number that turned out to be the right one on mine is an Gates T166.... Thanks |

thanx for all the tips.My timimg belt installation frustrations in retrospect are due to many unproblematic installations on a 90 vert. I did not expect the different tolerances on a 93 vert. which has the rounded teeth as opposed to the square teeth. Visually my belt looks good even after suspending it over a kerosene heater for 10 minutes and hot enough to require a cooling period so I could work with it. The carbon black in it just won't expand the belt i guess. Truckjohn, I think your're right. No mather what you try you cannot get it on except for the fact that it was on before I took it off albeit with some effort. As far as me obusing the timing belt it's because the timing belt abused me for 2-3 hrs. Edited by chessir, Oct 30 2013, 10:34 AM.

So.. To clarify... Did you get the belt with ROUND teeth and your cogs have SQUARE teeth? If so - you got the wrong belt... Check the belt # I posted above... |
