Timing Belt Vs Timing Chain Vs Timing Gear


Recommended Posts

Ano nga ba. Ang mitsu diesels naka timing belt, ang nissan naman they boast timing chain while isuzu uses timing gear, can you guys share your thoughts on these. Naputulan na kasi ako ng timing belt sa L300 delivary van ko and ang mahal ng nagastos ko to think puro replacement pa nilagay ko. Tsk tsk.

yung mga lumang model na toyota like corolla 91 has timing chain. Pag binuksan m yung engine oil cap while nk-on engine at lumalabas ang oil- timing chain yun. pag nasiraan k ng belt-affected yung mga valve mo, masisira yung pipe. better not to start the engine pg-naputulan ka.

kia besta 2.7 and the pregios have timing gears so i dont know if its safe to say that you would not have problems with the gear in the long run as far as i know my beetle 67 model uses gears also and its is still intact as far i can remember if ever i get to start it up again. also the isuzus are very noisy i think primarily to thier relatively higher compression ratios so high that some claim it is the reason to thier super tipid ness daw in diesel that is have a freind with taxis before gemini diesels they can attain a high 15 18 km per liter hehehe while i am happy with a 10 on my fx maybe a little higher on highways that with aircon all the time. Just a question you change the timing belt on the l300 and it broke again hmm how long did it last the new belt?

I used to own a 1990 Toyota AE92 1600 16valve and I remember having a timing belt and not a chain...

 

Maybe what you see beneath the oil cap are the gears connected to the double overhead cams...

Timing gears are the toughest among the lot however, gears are not entirely the best choice for timing an automobile because of the weight and complexity of gearing. Most timing gears require little adjustment this why they are often used in stationary machinery and prime movers.

 

Timing chains are the next most durable but they come with several inherent problems. Being metal, chains can suffer fatigue and expansion specially in extreme temperatures thus they become less and less accurate with time and conditons. Older cars used chains because this was the most viable form of drive, this also meant that most of these chains had to be part of the internal lubrication systems which in itself posed a significant number of complexities.

 

Timing belts became the way of the future, they are stuff and with proper replacement intervals they can help keep your engine in good tune as good or probably better than timing chains and gears. Just a caveat, replace you belts regularly do not wait for this to snap as it will cause massive engine damage.

tama just change them a few kms before the rated and most of all make sure where you will get your timing belts kasi had a friend who di change it hehehe but the second one gave way , way way far before the rated mileage again. some say if it is rated for 100k kms just do a 50 or 60km hirap talaga ma putulan the problem grows and you just dont know how big it will or may grow

but again that what they call swerte swerte rin minsan

yup... Honda's toyota's and mitsu's uses timing belt... its more quiet, easier to replace but breaks off easily thru wear and tear

 

Nissan's (proud owner) uses timing chain... sobrang bihira mag break nito.. if that happens then kailangan baba ng makina mo just to replace that... if not maintained well and mgkaroon ng slack sa chain then mas maingay sya... pero seldom na mag break ito... my nissan is already 13 years old and the chain is still in good condition

 

AFAIK isuzu's uses timing gear... dont know much about the pros and cons of a gear kaya no comment... :D

But if the car is 2nd hand, how will you know when to have the timing belt changed?

 

I bought this '97 Corolla GLi. At the time of the purchase, it had run a total of 121Thousand Kms. It's now on the 130 mark. Should I have it replaced na? Hindi pa naman bumabagal ung sasakyan so far.....

 

Get it done anyway. That's one of the first thing I get done after buying a 2nd hand car. I'd rather be sure and spend a little now than have a belt snap and spend a lot more.

I have an L-300 diesel. It has two belts inside the cover. The timing belt and the balancer belt. Mas manipis nga lang yung balancer belt. Kung sabay mo ito pinapalitan, it is always the balancer belt that gives away. Magbabago takbo at maingay makina. You can still drive it to an auto shop. It happened to me once. Galing talaga ng mitsu; bigyan ka muna warning. Basta palit ka between 60k to 80k kms. para safe. When that happened to me, more than 100k kms na tinakbo nung belt. I learned my lesson.

Not all Isuzu's have timing chains. there are a few Isuzu engines that use a belt.

 

oil spewing out of the cylinder head when opening the oil cap has nothing to do if it is timing chain or timing belt. the only sure way to tell is either to check the manual or open the cylinder head cover or on most japanese cars the timing gear cover.

 

when the timing belt brakes the parts that will most probably break are the valves, valve guide, valve springs and the piston or if the engine was revving really a whole lot of other parts in the cylinder head. what happens when the timing belt break is the valves on one or two of the cylinders will not be close during the compression and the piston will hit it, breaking the valves or itself.

 

replacing the timing belt at 60t or 70t kms is really recommended even if the manual says 100 just to take into account if the engine was driven hard by the previous owner. replacing the tensioner is also recommended with the change in belt. if you use a replacement belt instead of OEM subtract 20kms from the usual interval.

the main advantage of the timing belt butween the timing gear is the smoothness and quieteness.....the timing chain is somewhat a compromise between the 2... most smaller displacement diesel engines use any of the 3 to actuate the engine valves......but on bigger diesel engine the usual configuration is the timing gear, owing to its more robust nature

 

hope this helps

timing chain matagal masira, kahit luma na engine parang bago parin yung chain, nissan uses timing chains on their J engines found in local sentra's, down side lang nito is maingay pag tumagal na ng 5 years yung kotse

 

pero nissans RB and SR engines ata is timing belt...

 

timing belt naman breaks kung abused engine parati, pero normal city driving mga 70-100k kms ang life nya
