How to change timeing belt on 2008 suzuki forenza


Instructions
    • Disconnect the negative cable on your car battery. Make sure to wait for the engine of your Suzuki Forenza to cool off completely before you start working on it.
    • 2Rotate the engine using a wrench attached to a crankshaft bolt. Align the timing mark on the pulley to the 0o mark on the scale.
    • 3
    • Remove the screws and the bolts that hold the timing cover in its place and take the cover off. Loosen the bolts that hold the spring-loaded tensioner of the timing belt a little. Pull the tensioner away from the timing belt and then tighten the bolts again.
    • 4Pry off the timing belt from the pulley channels and the camshaft sprocket with a flat head screwdriver. Set the old timing belt aside and compare it with the new belt. The new belt should have the same width as with the old timing belt and the inside surface of both belts should have the same size of teeth.
    • 5Put the new timing belt on the sprockets and make sure it is positioned correctly. Loosen the bolts that hold the tensioner and pull the tensioner toward the timing belt.
    • 6Adjust the timing of the belt. Strictly follow the instructions on the Suzuki Forenza manual. When the timing is set, check if the timing marks on the can, crank and sprockets are still aligned.
    • 7Turn the engine with the wrench on the crankshaft pulley two whole circles until you reach the 0o mark.
    • 8Reinstall the timing cover and tighten the screws and bolts that hold the cover in its place.
    • 9Reconnect the negative cable on your car battery. Put the key in the ignition and start the car to check if the timing belt replacement was successful and that the car is running properly.

I have a 2004 Honda vtx 1300c and the speedometer quit working. I checked the battery connections and the fuse and they are fine. All the other lights and the odometer on the dash work. The speedometer...


its the speed sensor The Speedo sensor has a little plastic coupler that is driven off the hex head of the bolt that holds your countershaft sprocket on. If the countershaft sprocket bolt has backed off,it could've damaged that coupler. Or the plastic coupler has simply stripped out from working against that steel bolt head. Unbolt the Speedo sensor(it's just two little bolts)and remove it,see if the hex shape of the coupler is rounded out,or if the hex shape of the sprocket bolt is rounded. Either of these could give you erratic readings. If the bolts that hold the countershaft sprocket cover are loose,or the bolts that secure the Speedo sensor are loose,these too could cause an erratic Speedometer reading.

How do i get to the front sprocket on thye xjr1300?


You need to take the clutch slave cylinder off first, Yamaha say drain the clutch down but no need! £ bolts hold it on 2 are long and bolt in to the engine (the one at 12 oclock and the one at 10 oclock) the third is short (at 3 oclock) this only bolts in to the thin alli cover so be careful putting thin one back in as it will strip the thread as easy aas you like!!! When this is removed the cover can then be un bolted, again Yamaha say remove the starter but no need, 2 small bots at the top and a longer one at the top also 2 bolts sunk in to the cover, you will need a long reach 8mm socket to get to these, when all bolts are removed the gear selector needs to be removed, I found the easiest what is to remove the root rest with the gear selector attached, 2 allen bolts and a securing bolt at the front of the gear selector, a screw driver will open the gap to get the gear selectof off and the cover will come off reveling the front sprocket. You will need a 36mm socket (think that was the size) and there will be a washer that is bent over the nut locking it in position. Torque settings for all the external bolts is 10nm and the front sprocket is 38nm. hope this helps

Front sprocket oil leak


Get a new seal before taking the sprocket off. Remove the sprocket cover plate. You will see two small bolts holding a lock plate on the sprocket. Remove the bolts, lock plate and sprocket. Clean the sprocket shaft so the new seal is not damaged when installing. Now just pry out the old seal any way you can with a screwdriver and small hammer. Install the new seal flush with the casing.
