Need know how set timing on Yamaha v-star classic 2002


Ensure the line on the timing rotor with a T next to it is aligned with the notch in the timing window

Starting with the rear cylinder, ensure the camshaft locating dowel is aligned with the mark on the cylinder head at about 1 o'clock
Engage cam sprocket with cam chain so it will line up with the dowel & fit onto camshaft

The mark on the sprocket should now also line up with the other marks. Turn the cam sprocket clockwise to remove all slack in the chain, push against the runner through the cam chain tensioner hole to take up slack, this re-aligns all the marks

Bolt cam sprocket to shaft & fit tensioner. Turn crankshaft until the other line on the rotor aligns with the notch in the timing window
Repeat the above process for the front cylinder

Need to remove cilinderhead from a chevrolet trailblazer 2003


below are the instruction you well need to remove head .....good luck Removal Procedure
  1. Remove the air cleaner element.
  2. Remove the air cleaner outlet resonator. .
  3. Remove the powertrain control module (PCM) and engine wire harness bracket and related hoses and connections.
  4. Remove the generator.
  5. Remove the intake manifold.
  6. Remove the exhaust manifold. Do not remove the exhaust pipe from the manifold. Only have the manifold pushed off to the side of the engine.
  7. Position the A/C line out of the way towards the front of the vehicle.
  8. Disconnect the following cross-vehicle engine wiring harness connectors:
  9. • Engine coolant temperature sensor • Manifold absolute pressure (MAP) sensor • Ignition coils • Harness clamps at power steering pump • Wiring harness fastener at the right front inner fender • Throttle body • Camshaft sensors • Camshaft actuators • Fuel rail • Heated oxygen sensor (HO2S)
  10. Set aside the cross-vehicle engine wiring harness on the left side of the vehicle.
  11. Remove the camshaft cover.
  12. Partially drain the cooling system.

  13. Before performing one of the top dead center (TDC) procedures, break loose both the exhaust and intake camshaft sprocket bolts. Use a 25 mm (1 in) open end wrench on the camshaft hexes to hold the camshaft from turning. DO NOT remove the bolts.
  14. Perform one of the following methods for the service timing procedure.
  15. First Method--Rotate the engine clockwise by hand to TDC on the compression stroke by using a piston TDC indicator tool and/or dial indicator in the number 1 cylinder.
  16. First Method (continued)--The TDC indicator tool graduation marks on the shaft should note top of the piston stroke.
  17. First Method (continued)--When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats.
  18. Second Method--Rotate the crankshaft in the engine rotational direction clockwise until the number 1 piston is at TDC on the compression stroke. The word Delphi on the exhaust camshaft position actuator will be parallel with the cylinder head to cam cover mating surface. When the piston is at TDC, the flats at the rear of the camshafts will be facing up and level when using a straight edge across the camshaft flats. A 0.005 inch feeler gauge should not slide under the straight edge (1).
  19. Use a white paint pen or equivalent to place a reference mark on the harmonic balancer to the front cover for alignment purposes.
  20. Lower the vehicle.
  21. Important: If the timing is correct (TDC compression stroke number 1 cylinder), the camshaft flats will be in the up position.
    Install J 44221 to the back of the camshafts.
  22. Remove the upper timing chain guide to the cylinder head.
  23. Clean the timing chain and gears with brake cleaner or suitable solvent. Use a white paint pen or equivalent to place a reference mark on both timing gear sprockets and the timing chain to mark location prior to disassembly. It is recommended that the paint marks be in the 12 o'clock position.

  24. Install EN-48464 . It is important to install the tool with the proper orientation and to ensure that it is seated square against the timing chain and against the timing cover center bolt.


  25. The narrow ramp of the wedge tool needs to be placed so that it faces the timing chain.
  26. The wedge tool should be lightly seated using a couple of very light taps with a small plastic or brass hammer. The wedge tool will be fully seated against the tensioner after it moves about 25 mm (1 in).

Timing chain noise


Yes, that would sound about rite the xl125 r along with all the single hondas are pron to chain noise, easy fix, remove alternator l/ h cover, also timeing cover on cylinder head, mark plate and case with screwdriver for exact replacment, undo 10 mm bolt in end of camshaft and remove the atu unit take care not to loose the locating pin from the camshaft
Remove the pin if loose, undo the 2cover bolts and remove the cam cover, locate the timeing mark on the cam wheel and turn the engine until the mark on the wheel aligns with the mark on the case at about 12 oclock, then check the position of the lower pully and mark this, undo the top wheel bolts securing it to the camshaft, gently pull the wheel of the cam slightly and then hook the chain off the wheel, the cam wheel will now pass through the case opening,the cam chain will now come off the lower wheel, and can be pulled up and out over the end of the camshaft, and replacment would be in reverse order, checking alignment of all previously noted marks and security of all fixings before rotating the engine with a spanner and check it completes a full 360 degres before atempting to use the kickstart, the tensioner is addjusted by removing the top nut from the tensioner located on top of the crankcase lh side at the rear of the cylinder, then undo the 14 mm tensioner bolt, you could try first off screwing a 4mm screw into the tensioner, where the 10 mm bolt is removed, undoing the 14mm and pulling up on the screw with a pliers while tightening the 14mm locking device, as the tensioner is automatic this would be a manual addjustment and may remove the exsess slack

Can u adjust the timming chain on a yamaha xj 600 1998 model


The XJ600 has a self adjusting timing chain tensioner, although it's robust enough, like the previous post say's they can stick. To remove the adjuster look at the back of the engine on the cylinder head, the tensioner is there, two bolts hold it on one above and one below. to remove the tensioner there is a spring tensioner in the centre of the unit, undo this with care it hold the pressure spring in place on the plunger. Now remove the retaining bolts very carfully, equal turns on each bolts (do not take one out fully, leaving the other in place fully tight).
Once off the engine DO NOT ROTATE the engine. The tensioner should move freely, although there is a rachet system that locks it out, if it moves out freely then it's fine. To re-fit the tensioner release the tensioner make sure it's adjusted fully inwards and use a fresh gasket. The tensioner only firs one way, if it won't fit don't force it and it can be broken easily. Tighten both retaining bolts evenly and per the removal. Re-fit the tensioning spring and retaining bolt (do not over tighten) the plunger is self adjusting from here.
