Chain wrenches are commonly sold in industrial equipment or auto parts stores.
A chain breaker tool is the best tool to use for removing a stubborn drive sprocket from a motorcycle chain. It is specifically designed to break and remove chain links, making it easier to take off the sprocket.
right in front of the crankshaft pulley beside the oil filter....is the timing chain cover(two timing chain...#1 on the crankshaft sprocket, #2 on the cam sprocket. Need to lower the engine to access the timing chain. Timing chain, not necessary to be replace, unless they broke loose.Other than that it remain with the life of the van.
To replace a bike sprocket, you will need to first remove the chain from the sprocket. Then, use a wrench to loosen the bolts holding the sprocket in place. Once the bolts are removed, take off the old sprocket and replace it with the new one. Secure the new sprocket in place by tightening the bolts. Finally, reattach the chain to the new sprocket.
We find timming mark on the oil pump or on the block ,crankshaft sprocket and on the camshaft sprocket.
The bora v5 does not have a cam belt. It has two timing chains. The first is driven by a sprocket on the crankshaft. This first chain drives a sprocket connected to a smaller sprocket on a common shaft. This smaller sprocket drives the camshaft chain which drives the twin cam shafts. Both chains have tensioners.
Under the timing chain cover, attached with 2, 10mm bolts, directly to the right of crankshaft sprocket. Once the timing chain cover is off it will be easily visible.
1.8L and 2.0L Engines Disconnect the negative battery cable, then rotate the engine until #1 piston is at top dead center on the compression stroke. Remove the rocker arm cover, the front cover, and the oil pan. Depress or lock the shoe of the automatic chain adjuster in the retracted position. Remove the camshaft sprocket-to-camshaft bolts and the sprocket. Remove the timing chain from the timing sprockets. Using a puller, remove the sprocket and the pinion gear from the crankshaft. Remove the bolt or e-clip and remove the automatic chain adjuster. Inspect the adjuster pin, arm, wedge and rack teeth. Replace assembly if worn. Remove the chain tensioner. Check the timing chain for wear. Check the tensioner pins for wear or damage and replace if necessary. Replace the chain tensioner and adjuster using the e-clips or bolt. To install: Install the timing sprocket and pinion gear with the groove side toward the front cover. Align the key grooves with the key on the crankshaft, then, drive into position. Confirm the #1 piston is at top dead center, if not, turn the crankshaft so the key is turned toward the cylinder head side (#1 and #4 pistons at TDC). Install the timing chain by aligning the mark plate on the chain with the mark on the crankshaft timing sprocket. The side of the chain with the mark plate is on the front side and the side of the chain with the most links between the mark plates is on the chain guide side. Install the camshaft timing sprocket so the mark side of the sprocket faces forward and so the triangular mark aligns with the chain mark plate. NOTE: Keep the timing chain engaged with the camshaft timing sprocket until the sprocket is installed on the camshaft. Using a new gasket and sealant, install the front cover assembly. Install the rocker arm cover and oil pan. Refill the cooling system and the crankcase. Connect the negative battery cable. 2.8L and 3.1L Engines Disconnect the negative battery cable. Rotate the crankshaft to position the #1 cylinder at the top dead center of its compression stroke. Remove the front cover. Inspect the sprocket for chipped teeth and wear. Inspect the timing chain for wear, if the chain can be pulled out more than 0.374 in. (9.5mm) from the damper, replace the chain. Remove camshaft sprocket-to-camshaft bolts, the sprocket and the timing chain; if necessary, use a mallet to tap the sprocket from the camshaft. Using a puller tool, pull the crankshaft sprocket from the crankshaft. To install: Using an installation tool and a hammer, drive the crankshaft sprocket onto the crankshaft; make sure the timing mark faces outward. Using Molykote� or equivalent, lubricate the camshaft sprocket thrust surface and install the timing chain onto the sprocket. While holding the camshaft sprocket and chain vertically, align the marks on the camshaft and crankshaft sprockets. Align the camshaft dowel with the camshaft sprocket hole. Install the camshaft sprocket and torque the bolts to 17 ft. lbs. (23 Nm). Lubricate the timing chain with engine oil. Install the front cover and crankshaft pulley. Connect the negative battery cable. Start the engine, then, check and/or adjust the timing.
2 blue marks on chain -cam sprocket marks.yellow colour mark -crankshaft sprocket.make sure crank sprocket is at 12 o clock
Fig. 11 Valve Timing MarksRemove engine front cover as outlined previously.Remove crankshaft oil slinger.Crank engine until timing marks on sprockets are in alignment, Fig. 11.Remove three camshaft to sprocket bolts.Remove camshaft sprocket and timing chain together. Sprocket is a light press fit on camshaft for approximately 1/8 inch. If sprocket does not come off easily, a light blow with a plastic hammer on the lower edge of the sprocket should dislodge it.If crankshaft sprocket is to be replaced, remove it with a suitable gear puller. Install new sprocket, aligning key and keyway.Install chain on camshaft sprocket. Hold sprocket vertical with chain hanging below and shift around to align the timing marks on sprockets.Align dowel in camshaft with dowel hole in sprocket and install sprocket on camshaft. Do not attempt to drive sprocket on camshaft as welch plug at rear of engine can be dislodged.Draw sprocket onto camshaft, using the three mounting bolts. Tighten to specifications.Lubricate timing chain with engine oil and install cover.
Sprocket and chain and what?
To change a front sprocket, first ensure the motorcycle is on a stable stand and remove any necessary bodywork for access. Loosen the chain and remove the chain from the sprocket, then use a socket wrench to remove the retaining bolt or nut holding the sprocket in place. Replace the old sprocket with the new one, ensuring it's oriented correctly, and then reassemble by tightening the bolt and reattaching the chain. Finally, adjust the chain tension as needed and check for proper alignment before taking the bike for a test ride.
Crankshaft dot should be at the 5 o'clock position. Intake camshaft sprocket should have the "INT" mark at approx. 2 o'clock. Exhaust camshaft sprocket should have the "EXH" mark at approx. 10 o'clock. Timing chain has 2 silver links and 1 copper link. Copper link aligns with the mark on the Intake cam sprocket, 1 silver link aligns with the mark on the Exhaust cam sprocket, and the other silver link aligns with the mark on the crankshaft sprocket.
