My old one had the filter screen in place and there wear no signs of any clogs or debris(a possible reason the plunger is not extending) I simply transferred the screen after spraying it down w/ brake cleaner and installed it on the new part.

(Wondering if this TSB had already been performed by the dealer, before I bought the car in Mar. the old one looked very new and the teeth on the side showed no visible signs of wear(some on the internet had spoken about the teeth 'wearing down' as the exhaust cam slams back down) I replaced mine yesterday and I was able to back it out out to 3 clicks/indents on the 'plunger' before installing. Otherwise, the cams will be pushing or pulling on the cam chain, which can cause it to jump teeth with no tensioner installed. When you have the tensioner removed, you must be very very careful to keep the chain from going slack, and most critically you must have the cylinder #1 at TDC (or whatever position the FSM indicates engine crank position should be). Make sure the mating surfaces are absolutely clean on both the engine and tensioner (and filter if equipped) when installing the new tensioner. The FSM for my G35 noted that you can damage the tensioner by overtorqueing. DO NOT over-torque the tensioner fasteners. Keep your fingers clear of the piston when you remove the grenade pin.ĭo not remove the pin on the new tensioner until it is fully installed. I had my friend hold the chain guide in place while I unbolted the old tensioner, cleaned the area, and then bolted in the new tensioner. One or two teeth was enough to make it easy to remove the old tensioner. Then, allow the key to lock down & carefully insert the pin to lock it in position. To do this, you need to hold the locking key open (#1), then push down on the piston (#2) to retract it into the tensioner body. What I did on a previous car was use a short prybar to slightly compress the tensioner back down a few teeth. You can use a thumb tack (as pictured) to lock the tensioner from extending, much like how they do when the new ones are assembled & shipped.

Removing a tensioner while the engine is in the vehicle can be a challenge. The teeth on the tensioner piston allow it to extend out of the tensioner body as the chain, guides, and other components wear/stretch, and the stopper/key has a small spring on it to keep the piston from retracting which would allow the chain to jump teeth and cause engine damage. On top of that, the spring as well may be subject to wear, as well as the teeth on the piston & stopper/locking key. The FSM of my G35 said that when installing a new tensioner, you must run the engine at 3k rpm for a short period of time to charge the chamber up. Over time, this chamber doesn't seal off as well, and thus you can get a rattle at cold start until the engine build oil pressure. I know that the -A01 tensioners are to be replaced with -A02 per both Honda and Acura TSB's.įor those that don't know, the timing chain tensioners on modern cars often have a high-pressure chamber behind the piston. It's really important to have the correct timing in an engine, it's the only way they can run so when it's the scheduled time to replace a timing chain, make sure to get it done as it ensures the engine keeps ticking along nicely.Strange that some say their car didn't have the filter. It's rare for a timing chain to break completely but if it did the engine would stop. The vehicle will run roughly as the timing becomes out of sync. If a timing chain were to stretch you could notice power loss, engine backfires, rattle in the engine, rough idle and driving. If your Honda Accord has a timing chain installed it can stretch or fail over time and would need to be replaced to keep your engine running. Vehicle manufacturers did start replacing timing chains with timing belts to reduce engine noise and reduce costs as belts were a cheaper alternative however, timing chains have proven to outlast the belt and could be a more cost-effective option in the long run.

Belts eventually wear out, crack and disintegrate, while a timing chain can stretch and on rare occasions break however that usually happens long after a timing belt would have failed. Timing chains will typically outlast timing belts. A timing belt is typically of rubber and fibre composition and remains dry and is located externally under a timing belt cover. Due to the composition, the chain needs to be lubricated and is encased inside the engine. Honda Accord Timing chain replacement Why would my Honda Accord need a timing chain replacement?Ī timing chain or belt on a Honda Accord makes sure the crankshaft and camshaft are in time and the valves are opening and closing at the precise moment to coincide with the cylinder combustion.Ī timing chain provides the same function as a timing belt but the chain is made out of metal and looks similar to a bicycle chain.
