Question about Husqvarna Chain Saw 20" Bar

1 Answer

I put a chain on my 257 and tighten it and bolt on the cover. then i start it up and rev it for about 2-3 seconds. when i check the chain it is hanging about 1/2 in. below the bar. after sitting for about 3-4 minutes the chain tightens up tighter than i had it before. i've taken it to four different shops. what's wrong?

Sounds like the chain oiling system is plugged or has failed. Remove the bar and chain--start the engine and see if oil oozes from the engine side port where the bar fits up to. If ok, then check the small oil passages that run from the large holes in the drive end of the bar out to the chain groove on each edge--they commonly get plugged with sawdust and dirt. If there are small thin plates located on either side of the bar at the drive end, make sure that the one with a slot which couples oil feed from the engine to the bar is installed next to the engine. When adjusting the chain, make sure you can turn it by hand when everything is tightened. Be sure to oil the chain manually before running it the first time. Run the engine at speed and hold the bar tip near some cardboard for a couple of moments--it should throw off a thin line of oil. Hope this helps!

The chain has come off. I put it back but it is too loose. How do I tighten it


Should be a screw next to the bar. you can tighten it and it will tighten the chain. Keep in mind that the 2 bolts holding the bar and cover in place have to be loose to do this.

How do I set timing on a 2.3 Suzuki aerio engine


wow no job stated.
04 (2.3L) ill take a wild guess and say, you might be fiddling the cam
and doing something there, new cam, new lifters, new chain, new head, ? what?
FSM means factory service manual, ever heard of one?

the FSM is just lousy 4 bucks why not read that first. and not mess it up.

https://suzukipitstopplus.com/Products/1004-2004-aerio-service-manual.aspx

you said SET, so i can only assume its all apart. right then
you want to Instal the chain and time it, right so here are the fsm steps
no photos. log in and read the FSM for that.
  1. Check that match mark on crankshaft timing sprocket is in match with timing mark on lower crankcase.
  2. Install crankshaft timing sprocket as shown in figure.
  3. Apply oil to bush of idler sprocket and install idler sprocket and sprocket shaft.
  4. Install first timing chain by aligning dark blue plate of first timing chain and match mark on idler sprocket.
  5. Bring yellow plate of first timing chain into match with match mark on crankshaft timing sprocket.
  6. Apply engine oil to sliding surface of timing chain tensioner and then install it as shown in figure. Tighten tensioner nut to 18 ft. lbs. (25 Nm).
  7. With latch of tensioner adjuster No.1 returned and plunger pushed back into body, insert stopper into latch and body. After inserting it, check to make sure that plunger will not come out.
  8. Install timing chain tensioner adjuster No.1. Tighten the timing chain tensioner adjuster No. 1 bolt to 8 ft. lbs. (11 Nm).

    • Apply engine oil to oil seal lip, then install timing chain cover. Tighten bolts and nut to 8 ft. lbs. (11 Nm).
      NOTE Before installing timing chain cover, check that pin is securely fitted.
    • Before installing timing chain cover, check that pin is securely fitted.
  • Install alternator belt idler pulley. Tighten nut to 30.5 ft. lbs. (42 Nm).
  • Install alternator belt tensioner. Tighten bolts to 18.5 ft. lbs. (25 Nm).

  1. Before servicing the vehicle, refer to the Precautions Section.
  2. Drain the cooling system.
  3. Drain the engine oil.
  4. Remove or disconnect the following:
    NOTE The timing chain has 2 matching colored links and 1 uniquely colored link.

  5. Rotate the engine until the crankshaft sprocket mark aligns with the matching colored link (2) at the 5 o-clock position.
  6. Confirm that the INT diamond on the intake camshaft sprocket is aligned with the uniquely colored link at (1) the 2 o-clock position.
  7. Confirm that the EXH triangle on the exhaust camshaft sprocket is aligned with the matching colored link (3).
  8. Remove or disconnect the following:
    NOTE Use a 24 mm wrench to hold the camshafts to prevent them from turning.
    Timing chain tensioner, Fixed timing chain guide access plug, Fixed timing chain guide Upper timing chain guide, Exhaust camshaft sprocket, Timing chain tensioner guide Intake camshaft sprocket, Timing chain through the top of the cylinder head Crankshaft sprocket

    Fig. Aligning the exhaust camshaft sprocket (3).

To install:
  1. Install the crankshaft sprocket with the timing mark in the 5 o-clock position.
  2. Assemble the intake camshaft sprocket to the timing chain with the timing mark lined up with the uniquely colored link (1). Hand tighten a new intake camshaft sprocket bolt.
  3. Lower the timing chain through the opening in the cylinder head.
  4. Route the timing chain around the crankshaft sprocket and line up the first marching colored link (2) with the timing mark on the crankshaft sprocket.
  5. Install the exhaust camshaft sprocket with a new bolt loosely onto the exhaust camshaft.
  6. Align the timing mark on the sprocket with the last matching colored (3).
  7. If necessary, align the camshaft as follows:
    1. Using a 24 mm wrench, first turn the intake camshaft until the alignment feature on the back of the camshaft sprocket seats in the notch in the front of the intake camshaft.
    2. Turn the crankshaft 45 degrees in either direction.
    3. Turn the intake camshaft to the appropriate location.
    4. Turn the crankshaft back to top dead center (TDC).

    5. Install the compressed piston assembly back into the timing chain tensioner body until it stops at the bottom of the bore. Do not compress the piston assembly against the bottom of the bore.

  15. Install the timing chain tensioner assembly. Tighten to 66 ft. lbs. (75 Nm).
  16. Release the timing chain tensioner by compressing it approximately 0.08 inches (2mm). Feed a rubber-tipped tool down through the cam drive chest to reset on the cam chain. Give the tool a sharp jolt diagonally downwards to release the tensioner.
  17. Install the timing chain oiling nozzle.
  18. Install the timing chain guide bolt access hold plug with silicone sealant on the threads. Tighten the plug to 59 ft. lbs. (90 Nm).
  19. Install or connect the following:

    Camshaft cover. Tighten the bolts to 89 inch lbs. (10 Nm). Front cover with new gasket. Tighten the bolts to 18 ft. lbs. (25 Nm). Accessory drive belt tensioner. Tighten the bolts to 33 ft. lbs. (45 Nm). Crankshaft balancer pulley using a new bolt. Tighten the bolt to 74 ft. lbs. (100 Nm) plus 75 degrees. Accessory drive belt, Front fender liner, Ground strap to camshaft cover Ignition coil and module assembly, Fuel line bracket, Air intake assembly, Negative battery cable
  20. Refill the cooling system to the correct level.
  21. Refill the engine with oil to the correct level.

Cannot move the chain by hand after the bar has been tightened.


First be sure the chain is on going in the right direction. When looking at the bottom of the bar the sharp tooth should be going towards the motor. When you put chain back on are the chain teeth properly engaged in the sprocket on the motor. Remove the cover again, check that teeth are in sprocket. Make sure pin from adjuster screw is engaged in the hole in the bar. Before you tighten the cover bolts, make sure chain will turn by hand. If not adjust the adjusting screw. Once adjusted, tighten cover bolts. Check again after tightening bar.

Had plug in saw 2 weeks and it dose not work /// it spins but dose not move blade just loud clicking noise


ok i assume it is an electric chain saw? chain usually gets loose and can jump off clutch sprocket . to remedy this there should be atleast one nut or bolt sometimes two nuts or bolts depending on brand and model on the side cover where bar and chain inter the clutch area remove those and cover will lift off second there is a screw that faces front next to bar should be a regular slotted screw head loosenit all the way up till bar gets loose and remove bar by pulling away from saw this will come off veryeasy and chain shoouls fit on teeth of clutch sprocket and fit back onto bar tighten screw till chain tightens up on bar then replace cover and nuts on side cover but do not tighten the with one hand put tension on chain by pulling down on it while tightening screw till chain feels elastic snapping back to bar then toghten up nuts . chain should have no more then 1/4 inch slack around bar this is the correct tension youshould maintain.
