Are gear drives better than timing chains?

A gear driven system will always be much more stable, accurate, and last longer than any belt or timing chain, even a double-timing chain setup. The disadvantage to it is that they are typically noisy, require more lubrication than other methods and adds more overall costs to other motors designed without it.

Can the camshaft be chain driven?

Even where the crankshaft and camshaft(s) are very close together, as in pushrod engines, most engine designers use a short chain drive rather than a direct gear drive. A belt or chain allows much more flexibility in the relative locations of the crankshaft and camshafts.

What are the advantages of gear drive over chain drive?

Longer service life compared to both belt and chain drives. They can transmit large power. Gear drives have high transmission efficiency. They can transmit motion over small centre distance of shafts.

Do gear drives rob horsepower?

“Robbing horsepower is possible with the four-gear drive. What keeps the idler gear from falling off the block is that it’s wedged between the crank gear and the cam gear,” Morrison says. But if you can fix that idler, then it doesn’t create that drag, and it only gives the benefit of improved timing stability.”

Which is better a gear driven timing system or a chain?

Tap to check for your leaks. A gear driven system will always be much more stable, accurate, and last longer than any belt or timing chain, even a double-timing chain setup. The disadvantage to it is that they are typically noisy, require more lubrication than other methods and adds more overall costs to other motors designed without it.

When to use chain drive or gear drive?

A wide range of velocity reduction (1:1 to 1:40) is possible with gear drive. Chain drive is not suitable for high velocity reduction. It can be used when reduction is up to 1:10. Introduction to Machine Design by V. B. Bhandari (McGraw Hill Education India Private Limited).

Which is better chain or gear driven camshaft?

As with chain driven camshafts, timing belts can be found in every engine configuration. Configurations that require long length timing belts are generally not configured to support belts though. Gear driven camshafts supply the most accurate camshaft timing over the life of the engine. There is typically no maintenance of the gear drive required.

What are the advantages and disadvantages of gear drives?

Gear drives have some advantages and disadvantages. Most gear drives are a simple bolt-on installation that require few if any modifications. Most fit under the stock timing cover while others may require a special cover. Multi-position crank and cam sprockets with some sets allow as much as 12 degrees of cam timing adjustment.

When to switch to a gear drive Cam?

Changed oil 5k miles. it uses a qt between changes. I just found out from an independent wrench that I need to change the cam chain tensioner wear block. That is not mentioned in the scheduled maint, at least I can’t find. I have an extended warranty. So my thoughts are to change to a gear drive cam.
