VT1 VT2 CVT Push Belt 901100

The VT1 VT2 CVT Push Belt 901100 is a steel push belt used in a range of continuously variable transmissions, including VT1 and VT2 applications. Bosch-oriented CVT belt catalogs list 901100 as a 24 mm, 9-ring push belt with a belt length of approximately 208.9 mm. The same reference also appears for VT3 and several other CVT families, so correct transmission identification is important before ordering.

In the Chinese transmission-parts market this component is often called a CVT chain, but technically 901100 is better described in English as a CVT push belt rather than a conventional chain. A push belt is constructed from a large number of steel elements supported by multiple high-strength steel ring sets. It transfers torque between the primary and secondary pulley assemblies while continuously changing the transmission ratio.

This product is suitable for professional transmission workshops, CVT rebuilders, distributors and wholesalers. Customers should compare the original belt, transmission model and belt specification before installation.

VT1 VT2 CVT Push Belt Function

The VT1 VT2 CVT Push Belt operates between the primary and secondary pulley sets inside the continuously variable transmission. During operation, the effective pulley diameters change according to hydraulic pressure and transmission control commands. As the pulleys move, the belt transfers torque while allowing the transmission ratio to vary continuously.

Unlike a traditional roller chain, a CVT push belt transmits torque through specially formed steel elements and ring packs. Correct belt dimensions, ring construction and pulley contact are essential for reliable operation. Excessive wear, damaged elements, ring fatigue or pulley-surface damage can affect torque transfer and transmission performance.

Possible symptoms associated with belt or pulley wear may include slipping, abnormal noise, unstable acceleration, ratio-control problems or metal debris in the transmission fluid. These symptoms should not automatically be attributed to the belt alone. Hydraulic-pressure faults, worn pulleys, bearing damage, valve-body problems or internal lubrication issues can create similar symptoms.

901100 CVT Push Belt Specification

Reference 901100 is listed in Bosch-focused push-belt data with the specification 24/9/1.5PT/208.9/F5. The listed element width is 24 mm, the belt uses 9 rings, and the belt length is approximately 208.9 mm. The same data lists the belt as a production item and identifies 901064 and 901098 as successor or alternative references.

Because 901100 is used across multiple CVT transmission families, the reference number should be combined with transmission identification when matching a replacement belt. For VT1 and VT2 applications, customers can provide the transmission code, original belt markings, pulley photos and vehicle information.

If your product is supplied under the Bosch brand, the brand should be confirmed from the actual packaging before listing it as genuine Bosch. If it is an aftermarket replacement using the same reference, 901100 should be treated as a cross-reference rather than a brand claim.

VT1 and VT2 Transmission Applications

Current CVT belt catalogs list 901100 for VT1 and VT2 transmissions, and also for VT3, K310, K311, K312, K313, K410, JF009E, QR018CHA, M4VA, META, MLYA, SLYA and other compatible applications. This broad cross-application makes 901100 a useful reference, but vehicle model alone should not be used as the only fitment method.

The safest matching method is to confirm the transmission code and compare the original belt specification. When the gearbox has already been disassembled, technicians should also inspect the pulley faces for scoring, grooves or abnormal wear before installing a replacement belt.

CVT Pulley and Belt Inspection

A new VT1 VT2 CVT Push Belt should not be installed without checking the primary and secondary pulley assemblies. Damage on the pulley contact surfaces can quickly affect a replacement belt.

Technicians should inspect the pulleys, bearings, hydraulic pressure system, oil pump, valve body and transmission fluid condition. Metal debris inside the pan or filter may indicate internal wear and should be investigated before reassembly.

Clean installation conditions are important because CVT internal components operate with tight tolerances. Correct transmission fluid and professional rebuilding procedures should be used.
