What lengths do serpentine belts come in?
As with v-belts, width and length are the two parameters. Most OE replacement serpentine belts are 4 to 6 rib belts and the length is referred to in inches and/or millimeters.
How wide is a 6 rib belt?
Series: K & PK. Number Of Ribs: 6. Width Per Rib: 0.140″ Approximate Overall Width: 0.84″
How do you measure a rib belt?
Ribbed belts have lengthwise grooves on the inside. Measure the pitch of the groove, i.e. distance between projections, e.g. 3.54 mm = belt type PK. Count the number of grooves, i.e. the number of projections – e.g. 7, as shown in the picture. Width measurement is not usually accurate and is used only to check.
How do you read a serpentine belt size?
The first digit indicates an eight-rib belt, followed by “P” to identify metric belt sizing, and a “K” showing that this belt conforms to the SAE standard for rib sizing (3.56 millimeters wide for automotive-type serpentine belts). The final series of numbers is the effective length of the belt, given in millimeters.
How do you determine belt length by part number?
Automotive belts start with either 4L (12.5mm wide) or 3L (9.5mm). The number following it is the outside length of the belt in tenths of inches. The inside length of the belt is typically 2″ less for a 4L belt, and 1-1/2″ less for a 3L belt. An example would be 4L460, which would be 46″ long outside, 44″ inside.
How do you measure for a belt?
Lay the belt on a clean, flat surface. Start the tape measure at the hole you use and measure to the end of the belt, where it meets the buckle. Belts are measured in inches and you should round to the nearest inch. If you measure 36 inches, you will want to purchase a size 36 belt.
How wide is a 10 rib serpentine belt?
0.185″
The belt has 10 individual ribs, each with a 0.185″ V-width; they are bonded together by fabric to increase flexibility and heat dissipation.
How wide is a 12 rib serpentine belt?
2-1/4″
Gates 655L12 Micro-V Belt, L Section, 655L Size, 65.5″ Length, 2-1/4″ Width, 12 Rib.
What is a micro V belt?
Micro ribbed V-belts are flat belts with raised ribs that run lengthwise along one side of the belt. The ribs are thinner and closer together than the sections of standard V-belts, making them more flexible and compact. Also known as serpentine belts, they have a high tensile strength and are resistant to oil and heat.
What size is a 95 belt?
| Belt size (in.) | Belt size (cm) | Waist size (in.) |
|---|---|---|
| 34 | 85 | 32 |
| 36 | 90 | 34 |
| 38 | 95 | 36 |
| 40 | 100 | 38 |
How many ribs does a serpentine belt have?
In fact, the serpentine belt found on many automobiles is a type of ribbed V-belt. Ribbed V-belts have efficiencies similar to flat belts and can transmit more force (power) than traditional V-belts thanks to more contact area. This ribbed V-belt has seven ribs.
How do I find my belt size?
An easy way to determine belt size is to simply “add 2″ to your off-the-rack trouser size. For example, if you wear a 36” waist trouser, then a 38 belt size will be a safe bet. Most will find this simple formula works best for pants worn at a traditional height–close to the natural waistline.
Are notched V belts better?
A notched belt has grooves or notches that run perpendicular to the belt’s length, which reduces the bending resistance of the belt. Notched belts can use the same pulleys as cross-section standard V-belts. They run cooler, last longer, and are about 2% more efficient than standard V-belts.
