I have a 94 Honda Accord LX, with 175,000 miles. I recently had the therom pin and two pulley replaced because the biolt was stripped and the pulley wasd continuoly slipping off. Since the maintance, the car has been running fine but engine seems louder. Today, smoke was coming from the pulley unit and I can smell a stronger chemical odor. I smells like burning rubber or metal not oil. Before, going back to the mechanic I want to get a idea of what this could be. Thanks
Most likely the belts werent installed correctly and are rubbing on the pulley...they also can be too tight as well..that smell is so strong it will make u sick so do breathe it in ... have the mechanic inspect his/her work.. definitly a belt and pulley rubbing..

when the crank pulley came off it may have hit the other pulleys or the belts could have damage the timing cover. have your mechanic to check the clearance of all belts
remove but dont disconnect the power steering pump to get clearance , remove splash shield guard at the wheel , remove motor mount but have a jack wit a block of wood under the oil pan to support the engine . . that should give you clearance to remove the crank pulley . .
jack up on stands, remove LF wheel and water shield. disconnect battery, buy a crankshaft pulley holding tool from OTC, swing p.s. reservoir out of the way, remove both accesory belts, front motor mount, valve cover, dipstick and tube, crank pulley, timing belt cover, set engine at TDC #1 (align marks), remove nut on tensioner shaft to loosen both belts, remove the belts and tensioners (replace all), replace water pump NOW, install timing pulley, reinstall spring (use dipstick tube bolt to hold back the timing pulley with the slot in the bracket on the pulley until the belt is installed), install balance shaft belt, pulley and spring, once tensioned rotate engine once and retension by loosening the nut and retightening. Make sure the marks are still lined up, and reinstall everything. New valve cover gasket set with silicone in the corners. fill with coolant and bleed system once finished. it is a good idea to also change all the oil seals while you are in there.
The tensioner pulley is not turning??? Have you been burning up belts left and right?? Is the belt tight against the tensioner pulley?? You need to check to make sure that pulley is operating correctly. Are you getting good charge out of your altenator?? Is it hard to turn do to lack of power steering?? Have you thrown the belt multiple times?? If that pulley is not spinning there is only to causes for this. Either the pulley is froze, or there is no tension against the pulley. If the pulley is frozen you should be burning up belts often. The tensioner pulley spring is broke and not holding the proper tension. The belt might still be rotating, but the belt will not be rotating the other accessories attached like it should be. My chrysler van has a dual belt set up and yes if the tension pulley is not moving then you will be lacking the rotation need to make the ac compressor operate properly.
Well basicaly there is no adjustment it has timing marks and the belt goes on with the marks on the points.cam pulley has a stamped mark up with line marks that go evenly one on each side has to be even with top of the head.crank pulley the woodruff key goes straight up facing the cam pulley.The balance pulley has a v mark on the pulley and a mark on the block and those go together, dont worry about the water pump there is not timing mark on that.Good Luck
While wearing safety goggles and engine switch off.
Your 95 Accord comes with a 2.2L (4 cylinder)
I believe the 2.2L has two belts: power steering and alternator (with or without A/C - different belt applications). If you are replacing belts note the routing of each one.. . In any case these belts are not easy to replace . Each of the belts has its own manual tensioner. You should have pry bar or lever to push the tensioner back to release the tension on the belt.
There is not a lot of room to work between the pulleys and body of car (the engine is transversely mounted). Slip the belt off any pulley you can reach. Carefully release the pry bar on the tensioner pulley. To replace belt reverse the above step. Do not pinch or crimp the new belt.
You may also want to consider the timing belt also.
Crankshaft pulley (harmonic balancer) removal- disconnect neg battery cable, remove belts, it would be a good idea to soak the bolt w/ penetrating oil overnight, there is a special 'crankshaft pulley holding tool' available to secure the pulley while removing and installing the bolt. Some parts stores loan tools for free if u purchase parts from them, I don't know if this is available, but it would be worth checking out. Attach holding tool and remove bolt securing pulley. Carefully remove pulley from crankshaft, Do NOT pry off. Remove key from crankshaft sprocket, Install: install key on crankshaft sprocket, slide pulley on, apply clean oil to bolt threads but NOT to washer contact surfaces, secure crankshaft w/ holding tool, tighten to 159 ft lbs (91-93 Accord), install belts, re-attach neg cable.
