What kind of flywheel does a Ford Mustang use?
AOD transmissions used a 164 tooth flexplate. Mustang T5 transmissions used a 157 tooth flywheel and a 10.5″ or 10″ clutch disc. Ford light-duty trucks often used a 164 tooth flexplate and an 11″ clutch disc, though some heavy-duty trucks used much larger clutches.
How to tell the difference between Ford flywheels and flexplates?
If you have a known unit laying around, you can use it to compare against an unknown unit to see what it is. Once you know what to look for, you can easily tell the difference between 28oz and 50oz imbalance pieces by looking at the back side. The 50oz units will have a much larger weight on them.
What happens if you put the wrong flywheel on the engine?
If you put a flywheel/flexplate with the wrong imbalance on your engine and run it, your main and rod bearings will take a serious pounding due to the vibrations and will likely give out in just a few miles of driving.

Where is the offset weight on a flywheel?
On a flywheel, the offset weight is often a series of drilled holes around the outside of the flywheel instead of a fixed weight. (Image/Jeff Smith) I am looking for the right flywheel for my Gen VI 454 engine. The date code on the block is K106, and the engine casting number is 12550313.
How big is an ounce of imbalance in a flywheel?
To put this in perspective, there are 28.3 grams in an ounce. One ounce of imbalance located one inch from the crank centerline will create an imbalance force equivalent to 31.9 pounds at 6,000 rpm. At 2,000 rpm, it would be 3.5 pounds of force. It’s possible that you could feel that imbalance even at 2,000 rpm.
What kind of flywheel do I need for my Clutch?
A stock flywheel that would accommodate your flywheel is normally offered as a nodular iron piece for normal street driving. This would be a 42.5 ounce-inch spec externally balanced offset weight. The second option is a SFI-spec steel flywheel. Most of the high performance clutch manufacturers would offer one.
What’s the price of a 2013 Ford F350?
On the other end, a Platinum edition F-450 starts at over $68,000 and can cross the $70,000 mark with options. On F-250 and F-350 models, the diesel engine is roughly $8,000 extra (it’s standard on the F-450). At its base price, the Super Duty is competitive with its Ram and GMC/Chevy rivals.
What are the competitors for the 2013 Ford F250?
To this end, the 2013 Ford F-Series Super duty has only three major opponents: the Chevrolet Silverado HD/GMC Sierra HD twins, and the Ram 2500/3500. Like its competitors, the Ford Super Duty offers powerful gasoline or diesel engines that can haul enormous loads.

What’s the towing capacity of a 2013 Ford F250?
Braking capability and payload and towing capacity have been increased in what seems a never-ending quest for bragging rights in the heavy-duty truck segment. The 2013 F-Series Super Duty can now conventionally tow up to 18,500 pounds, and has a maximum 5th-wheel trailer tow rating of 24,700 pounds.
What causes a flywheel to fail on a diesel engine?
On diesel applications, anything that causes the engine to run roughly (bad fuel injectors, improper injector timing, loss of compression in a cylinder, etc.) may produce enough vibration to cause premature failure of the damper springs or nylon spacers inside a dual-mass flywheel.
When to replace a flywheel on a clutch?
The flywheel should be considered a wear item just like the clutch, and should be replaced when a new clutch is installed. Surface wear is another reason for replacement.
How to check for worn slip ring on flywheel?
To check for a worn slip ring, block the engine so it cannot turn and partially insert two long bolts in the bolt holes on opposite sides of the clutch cover. Insert a pry bar between the bolts and try to rotate the secondary flywheel with respect to the primary flywheel.
When do you apply torque to a fly wheel?
The tendency of a moving body to change its state of motion is called inertia.If the inertia of flywheel is high,considerable amount of torque is needed to be applied.The property of inertia is applicable to every object since it is having mass.

How much does it cost to replace a dual mass clutch?
Most of these units are not designed to be disassembled or serviced by technicians, so replacement is recommended if the unit shows a lot of wear or is making noise. Dual-mass flywheels are very expensive to replace. The list price for the flywheel alone is typically $800 to $1,100.
What causes a clutch to vibrate on a flywheel?
The cause is an imbalance between the engine, flywheel and clutch. The fix for this condition involves adding a stack of washers to one or more of the clutch cover bolts to change the balance of the rotating assembly. The idea is to add weight at various locations around the cover until the vibration goes away.
When did they start using dual mass flywheels?
Dual-mass flywheels are a unique kind of flywheel that have been used on a variety of pickup truck and passenger car applications since the late 1980s. You’ll find them on 1987 Ford F-Series 6.9L diesels, 1987-98 Ford F-Series 7.3L diesels, 1992-1996 Chevy/GMC 6.5L diesel trucks and 1992-02 Chevy/GMC 8.5L diesel trucks.
