Hi all- the small belt tensioner bolt broke on my 92 accord ex. Actually, its the tensioner adjusting bolt to be more.exact. its not for the timing belt, but for the smaller.belt. my question is, if i have enough tension by simply pressing down on on tensioner pulley and tightening the 14mm tensioning nut, is the tensioner adjusting bolt function necessary? Its gone be a real.challenge to extract that broken bolt. Thanks for any help i can get. Im very new to working on cars.

 

I moved your post. Please read the rules and do not post help questions in the DIY section.

 

Do you mean the PS belt or Alt-AC belt?

Once bolt is broken, bolt tension is gone, so bolt should back out easily w/ vise grips. New bolt from Honda and you're back in business.

Friction of pivot may be adequate to hold belt tension. You could try and see.

Usual reason for this problem is failure to release lock nut before tightening or loosening. Is this what happened?

good luck

 

I think the op is talking about the balance shaft belt and tensioner.....?

 

Yes, the balance shaft belt tensioner, but specifically the adjusting bolt that holds a bracket to which a spring is also hooked on to. That sucker broke as i was tighhtening it and now the broke off part is stuck in the hole. I trying to lower the engine enough to have access to the hole bia the engine well, i took out all 3 engine mount bolts but engine not really coming down...my plan was to get access to tjat hole so i can try and.somehow drill out the broken bolt..not sure how to.do that yet though. Other than lowering engine my only access to the hole is over the top of engine but all.i could do from there is try to see if i can stick a bolt remover and.turn it witj.a.ratchet....i really dont.know.what to do...any ideas are greaatly appreciated. And sorry for posting in wrong place.

 

Is any part of the bolt sticking out of the threaded hole?

 

Actually, no. Nothong sticking out. The broken bolt is inside the hole about 1/3 ways deep. Would drillin out be out of the quastion? How could i bring engine down enough, if eben possible? .thanks dor replies.

 

Still not sure which bolt you broke.

Is it the center pivot bolt that holds the pivot arm (one end attached to spring and other end engages/pushes the tensioner assy. If that bolt is broken, I'm sure you can't use the normal tensioning procedure. But you might be able to manually push the tensioner idlers against the belts and lock the 14mm nut.

If it's the temporary 6mm lock bolt this is a much better situation, as it only holds the tensioner in the fully slack position while you install the timing belt and balance shaft belt. It is removed after the tensioner is released (bolt slacked). The belt tensioning process is performed after the 6mm bolt is removed. It might be tricky to install timing belt w/o the bolt but I think you can do it be manually pushing the tensioner assy to slack position and snugging the 14mm nut.

Some advice, get a torque wrench if you aren't comfortable w/ manual tightening by feel.

good luck

 

Yeah, thats the one. I tried justp oressing down and tightening 14mm nut and seems it kept tight but after rinning engine for a.short while belt felels loose some.

 

Timing Belt will have some slack on the "return", from drive back to camshaft sprocket via the water pump.

Rule of thumb I've seen is that you should not be able to twist more than 90 degrees.

good luck
