On a colt 5 ride on lawn mower - how can I tighten the drive chain.


Most drive chains will be tensioned by loosening one of the gears and sliding it in the direction of tension and retightening the bolt. Some chains are equipped with a tensioner that will require a bolt to be loosened and a screw turned on the tensioner to achieve tension

Drive Chain Replacement on Stairmaster 4000PT Stepper


Replacing the Drive Chain on Stairmaster 4000PT
    1. Remove the bottom cover.
  • Remove the master link from the drive chain.
  • Remove the drive chain from the sprockets.
  • Reinstall the drive chain, ensuring the master link is properly installed.
  • Check the drive chain tension. There should be a total of 1" to 1-1/2" (2.5 to 4.0 cm) of play, up and down, at the slackest point in the chain. If the drive chain tension needs adjustment, refer to the "Drive Hub Assembly" section.
    WARNING: If the drive chain is too tight, the drive train will wear excessively, shortening the life of the drive hub assembly. If the chain is too loose, the machine will be noisy and will operate at less than peak efficiency.
  • Lubricate the chain with 30W motor oil and wipe off the excess.
  • Reinstall the covers.

How can I tighten chain drive belt?


Chain belt? Don't think so. There is a timing chain and a timing belt. Timing chains on automobiles are generally non adjustable and are tensioned by a hydraulic tensioner and require no attention. Some timing belts are also tensioned by a hydraulic tensioner requiring no service. Some timing belts are also tensioned by a cam tensioner that can be adjusted but are rarely in need of servive unless the timing belt is being replaced

Need to put a new chain on a Husqvara 235 14 inch chain saw?


Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.
Remove the bar nuts and remove the clutch cover (chain
brake). Take off the transportation ring.
Fit the bar over the bar bolts. Place the bar in its rearmost
position. Place the chain over the drive sprocket locate it in
the groove on the bar. Begin on the top edge of the bar.

Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
Fit the clutch cover (chain brake) and locate the chain
adjuster pin in the cut-out in the bar. Check that the drive
links of the chain fit correctly on the drive sprocket and that
the chain is in the groove on the bar. Tighten the bar nuts
finger-tight.
Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the
underside of the bar.
The chain is correctly tensioned when it does not sag from
the underside of the bar, but can still be turned easily by
hand. Hold up the bar tip and tighten the bar nuts with the
combination spanner.
When fitting a new chain, the chain tension has to be
checked frequently until the chain is run-in. Check the
chain tension regularly. A correctly tensioned chain
ensures good cutting performance and long life.

    1. Install the timing chain by performing the following procedure:
    1. Verify that the crankshaft sprocket timing mark is aligned with the mark on the oil pump housing.
    2. Place the left side primary timing chain sprocket onto the chain, while aligning the timing mark on the sprocket to the 2 plated links on the chain.
    3. Lower the chain with the left sprocket through the left cylinder head opening.
    4. Loosely position the left camshaft sprocket over the camshaft hub.
    5. Align the plated link to the crankshaft sprocket timing mark.
    6. Position the timing chain around the water pump drive sprocket.
    7. Align the right camshaft sprocket timing mark to the plated link on the timing chain and loosely position the sprocket over the camshaft hub.
    8. Verify that all the plated links are aligned to their proper timing marks.
    1. Install the left lower timing chain guide and tensioner. Torque the bolts to 21 ft. lbs. (28 Nm).
      NOTE Inspect the timing chain guide access plug O-rings before installing. Replace damaged O-rings as necessary.
    2. Install the timing chain guide access plug to the left cylinder head and torque to 15 ft. lbs. (20 Nm).
      NOTE To reset the timing chain tensioner, oil will first need to be purged from the tensioner.
    1. Purge oil from the timing chain tensioner using the following procedure:
    1. Remove the tensioner from the tensioner housing.
    2. Place the check ball end of the tensioner into the shallow end of the Tensioner Resetting Special tool 8186.
    3. Using hand pressure, slowly depress the tensioner until oil is purged from the cylinder.
    4. Reinstall the tensioner into the tensioner housing.
    1. Reset the timing chain tensioner using the following procedure:
    1. Position the cylinder plunger into the deeper side of the Tensioner Resetting special tool 8186. Apply a downward force until the tensioner is reset.

    WARNING

    Ensure that the tensioner is properly reset. The tensioner body must be bottomed against the top edge of the Tensioner Resetting Special tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.

    1. Install the chain tensioner into the right cylinder head.
    2. At the right cylinder head, insert a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
    3. Turn the left camshaft by inserting a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
    4. If necessary, rotate the engine slightly clockwise to remove any slack in the timing chain.
    5. To arm the timing chain tensioner: Use a flat-bladed prytool to gently pry the tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner extends.
    6. Inspect and replace the timing chain cover gasket and oil seal.
    7. Apply a 1 / 8 in. (3mm) bead of sealer at the parting line of the oil pan and engine block.
      NOTE When installing the timing cover, guide the seal over the crankshaft to prevent damage to the seal-s lip.

    THE CHAIN SLIPPED OFF HOW DO YOU GET IT BACK ON 14 IN HUSQVARNA


    There's two 1/2 inch nuts on the side of the cover from which the bar protrudes.
    Remove these nuts and the cover -- leave the bar loosely in place.
    Look for a slot-head chain-tensioning screw (may be on front under the bar, or perhaps on the side).
    Turn this tensioning screw counter clockwise -- you will notice a pin moving back towards the drive clutch -- this pin fits into a hole on the bar and is used to set the chain tension by pushing the bar away from the drive clutch.
    Once it is loosened, the bar can be pulled closer to the drive clutch, allowing you to fit the chain back onto the bar -- be careful to align the drive teeth on the chain into the slots on the drive clutch.
    When the chain is back in place, turn the tensioning screw clockwise to tighten the chain onto the bar.
    Replace the cover and put the nuts back on only finger-tight.
    Tighten the chain some more using the tensioning screw.
    Tighten the 1/2 inch nuts fully.
    Note: The chain needs to be quite tight -- lift it by a link and be sure it does not come out all the way from the bar.

    Timing belt or timing chain?


    You 98 Corolla has a timing chain that it internal and need no normal maintenance. It uses a hydraulic/spring tensioner to keep things tight and as long as its quiet, everything is fine.
    Your drive belt (not to be confused with a t. belt) is the external belt you see on the passenger side of the engine. It drives you alt, water pump, A/C and power steering. It uses a spring loaded tensioner to keep the belt tight. These can weaken over time and cause a rattle noise and belt slippage.

    I have a 99 dodge intrepid that threw a rod and my father-in-law and I have been trying to time the car for a year now. We get number one piston up but the mark on the oil pump doesnt line up with the mark...


    I'm not sure what you may be "doing wrong", but here is the manufacturer procedure for aligning the timing marks.
    d753c93.gif
    98f82f3.gif
    ^Refer to this diagram during step 12.
    046beb2.gif
    ^Refer to this diagram during step 13.
    95add8f.gif
    ^Refer to this diagram for step 19.

    1. Align crankshaft sprocket timing mark to the mark on oil pump housing. NOTE: Lubricate timing chain and guides with engine oil before installation.
    2. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links.
    3. Lower the primary chain with left side sprocket through the left cylinder head opening. NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.
    4. Loosely position left side camshaft sprocket over camshaft hub.
    5. Align timing (plated) link to the crankshaft sprocket timing mark.
    6. Position primary chain onto water pump drive sprocket.
    7. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain and loosely position over camshaft hub.
    8. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.
    9. Install left side lower chain guide and tensioner arm. Tighten attaching bolts to 28 Nm (250 in. lbs.). NOTE: Inspect oil ring on chain guide access plug before installing. Replace O-ring as necessary.
    10. Install chain guide access plug to left side cylinder head. Tighten plug to 20 Nm (15 ft. lbs.)
    11. NOTE:
    To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.
    12. Purge oil from timing chain tensioner using the following procedure:
    a) Place the check ball end of tensioner into the shallow end of Special Tool 8186.
    b) Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
    13. Reset timing chain tensioner using the following procedure:
    a) Position cylinder plunger into the deeper end of Special Tool 8186.
    b) Apply a downward force until tensioner is reset. NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball. CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
    14. Install the reset chain tensioner into the right cylinder head.
    15. Position tensioner retaining plate and tighten bolts to 12 Nm (105 in. lbs.).
    16. Starting at the right cylinder bank, insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 in. lbs.).
    17. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 in. lbs.).
    18. Rotate engine slightly clockwise to remove timing chain slack, if necessary.
    19. To arm the timing chain tensioner: Use a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner is armed (extends).
    20. Install the timing chain cover, crankshaft damper, and cylinder head covers.
    21. Install camshaft position sensor and connect electrical connector.

    Hope this helps!
