Question about 2005 Honda CRF 250 X

1 Answer

Bike is a 2005crf250x. Need timing chain slack.

I didn't have enough slack in the timing chain to get it over the cam gear. The chain tensioner is not the problem. I have removed the head and jug. The chain feels like it may be caught up on something in the crank. Could that be possible?

Lift the chain with one finger then turn the crankshaft several full turns by hand. Inspect the full length of the chain during rotation. Any obvious damage? Does the chain revolve smoothly around your finger? If all seems okay then the problem is probably not in the lower end. Some chains are continuous and do not have a master link. Some do have a master link. If you have a master link then separate the chain by removing the link then place both ends of the chain onto the cam sprocket and reconnect the link. If you have a continuous chain I would need to see first hand what is going on. In any event, be certain the timing marks on the flywheel and overhead cam are correctly lined up during installation.

To install a timing chain on a 1990 Buick Skylark

My Skylark used to make a diesel sounding noise while idling and it turned out to be a worn timing chain which I replaced myself. Some models have a timing gear instead of a timing chain and these can be very noisy as well (2.5 Iron Duke). By 80-90,000 miles you should replace the chain and or the gear set. Before you install your new chain make sure that tensioner is in the box and is compressed with a small metal clip. You will not be able to install the chain unless the tensioner is compressed. There simply won't be enough slack in the chain to reach the cam and crank shafts. While you are replacing the chain be sure to spend a couple of extra bucks and install a new timing cover seal. This seal keeps oil from leaking out of the oil pan behind the harmonic balancer. It is definitely worth the effort to put it in while it is apart.

Dirt bike cam shain tensioner

You must remove the entire tensioner and leave it out while you swap out the sprocket. Set it to it most retracted position and then install. Adjust it after it is installed. Make sure you have some slack or you will break the chain.

How do I line up my marks on cam shaft and flywheel to set timing

Hi mate didn't get any info on what bike you are timing but this procedure is simular for most and is specific for WR YZ 250 426 and 450

set piston to TDC (top dead centre) this can be done by spinning the fly around until you can see the (i) mark stamped on the flywheel line up with the marks on the inspection plug hole (engine case) good idea to probe the cylinder through the spark plug hole to confirm the flywheel mark is correct (I have seen several 426) where the TDC mark does not give accurate TDC on piston so worth second guessing this process.

once TDC is set do not allow piston to move from this point on - starting with the exhaust cam with no slack on the cam chain the dot stamped on the cam sprocket should align with the face of head with the cam lobes pointing outward roughly 45 degrees towards the front wheel when this in place

you do the same with intake cam except the cam lobe will face opposite direction outward and the should be a dot aligning to the head

double check before you go further that when you put your finger in the chain tension hole and you tension the cam chain that when all slack is taken from the cam chain that your dots on both cams align with head face and that you still have piston at TDC if all checks out then this is timed set correct so torque all the cam caps back up install chain tensioner and the recheck all fly wheel marks are in correct position and piston is at TDC and the dot on each cam sprocket aligns to the head if it doesn't then re do the process

don't be surprised if this takes a few attempts as it takes the best of us usually at least two attempts to get all marks to align correctly thats why best to check and double check before you bolt it all down then you can adjust just by lifting one cam out and moving one tooth either direction

You have little room to play with and when you start putting chain on the cam sprockets you will find very little extra chain length to play with you may need to wiggle tug and pull both cams together to get them back in each time but go slow and gentle they do go in they just need to be encouraged

I happy to elaborate on any point if you need - good luck

Noise from timing chain how does the tensioner operate

Depending of the bike , the tensioner should be a Teflon push plate or a metal plate which pushes on the chain to reduce the slack in the chain .Adjustment can be made manually from the back of the cylinders but all tensioner are different .Some do have a spring which could need replacement . sometimes if the timing chain is too old it make noise due to the tensioner out to the maximum tension and does not apply enough pressure on the chain and therefore noise and slight vibration .

Chain will not move on chainsaw

Normal 0 This will be the basic instruction for most common saws. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle if the saw is equipped with a chain brake on the handle. Loosen the bar nuts on the clutch cover. Loosen tension screw or other adjuster (thumbscrew) to allow the bar to be moved toward the engine. Some saws have this tension adjustment built into the bar. This will provide enough slack in the chain to able to reinstall it. It may be necessary to remove the side cover to gain access to the clutch/gear assembly on the side of the engine if the chain also jumped the gear here. Remove the cover, inspect for any debris or other obstructions in this area. If none, replace the chain back over the drive gear and in the bar groove all the way around the bar. It may be necessary to turn the bar adjuster screw more to provide enough slack in the chain to do this. Once the chain is in place reinstall the cover and bar lock nuts. Snug up the nuts but do not tighten these. Turn the bar/chain adjuster screw to tighten the chain on the bar (take up slack). I usually tighten to a point where there is no slack between the chain and the bottom of the bar and I can still turn the chain easily around the bar by hand. With experience you will get the feel for this chain tension. Once the chain is properly tensioned, tighten the bar lock bolts/ nuts on the side cover.

Some Poulan Pros have an adjuster screw on the front of the engine case right beside the bar, some have a tool less adjuster on the clutch cover, and some have a slot in the bar for adjusting the chain tension.

I hope this helps you out.

Suzuki DR650RS Camshaft is broken into two parts. what could be the reason for breaking axles

In normal operation, there is no way the chain or valve springs could break a shaft. The only possibility, other than a defective camshaft when the bike was new, is that the cam chain was so loose the slack bound up around the sprocket causing enough pressure to break the shaft. Replace the chain, sprocket and camshaft and check the operation of the cam chain tensioner assembly. Please rate my answer.

How to change the timing chain?

By rights you should pull the sidecase off the motor & the rocker cover, & fit an endless chain over the crankshaft to the cam(s)if you can get a chain with a joining link or get one from a bike shop & ask them to split it for you, you can just take the top cover off the motor, line the cam timing up (piston @ top dead centre(should have timing mark), cam lobes (pointy part) facing as far as you can get both at the same time from the cams, remove timing chain tensioner, let old chain go slack, join new one to it & loosely pull through, make sure bike is upright when you put new one in so chain locates on bottom sprocket properly, then reassemble chain & peen pins over with ball peen hammers.

Installing cam chain on 09 CRF 450. It seems that I don't enough slack in the cam chain to fit it around the camshaft sprocket.

check that the new cam chain is roughly the same length as the old one, ensure that it is properly installed on the bottom (crank) sprocket, make sure that your tensioner is backed off fully, even after all of this you will still find that the chain seems too short, tip the cam to the left side of the engine & your chain should slip on..double check your cam timing with cam cap snugged down & tensioner released.

Poss loose timing chain- is there an external adjuster?

The cam chain tensioner on the R6 is external but it is also automatic. If you are hearing cam chain noise, the tensioner could be getting close to ratcheting up one notch to quiet the chain down. The chain could be stretched enough to make noise but not loose enough to let the tensioner take up the slack yet.
You can loosen the adjuster mounting bolts very slowly until you hear 1, and only 1, click. Then bolt the tensioner back down and start the engine and see if it is noticeably quieter. If it is, leave it alone. If the noise is unchanged, the chain was not loose and the noise is coming from somewhere else.
