RV Parts & Repair

Pump repair

Custom Cylinders International Inc. can repair or replace name brand RV hydraulic systems and complete RV power packs or RV hydraulic pump/reservoir systems.


In 1990 CCI was approached by the Taylor Newcomb Company to develop cylinders for a new product for the travel trailers and motor homes. The system that was proposed required two hydraulic cylinders that would operate in tandem to open and close a movable room assembly built into the side of an RV. In 1991 prototypes were shipped to the newly formed company Hydra-Slide, and the industry has not been the same since. Fleetwood Corporation became the primary customer for the Hydra-Slide system, and CCI was shipping 1500 cylinders per month to the 9 Fleetwood plants in the U.S. and 2 in Canada.

The RV industries constant goal of increasing profits eventually resulted in the introduction of electric actuated systems, and the hydraulic systems lost most of the market. Although the hydraulic systems were more reliable and have a longer life span, the electric systems were considerably less expensive. In addition to the higher initial cost a second negative factor was that hydraulic systems are considerably more complicated to repair. The RV Service Departments had little or no experience with hydraulics, and the Service information from the various slide-out manufacturers was totally inadequate.

CCI continued to supply replacement cylinders to Hydra-Slide, Fleetwood, RV dealers, Kwikee, Equalizer Systems, Dutchmen Industries, Dewald Fluid Power, and private repair companies. In late 2008 CCI began to receive requests for repair information from the Fleetwood dealers for the Hydra-Slide hydraulic system. By early spring the volume of those requests had dramatically increased, due to the recent closing of Hydra-Slide Corporation and Fleetwood RV Industries. CCI initiated a program to develop a data base of the original Hydra-Slide system components, and developed a replacement system for the original hydraulic pump/reservoir. In parallel development CCI has initiated an aggressive program to diagnose and repair complete hydraulic systems from other manufacturers, i.e. Power Gear, Monarch Hydraulic Pumps, J.S. Barnes pumps, Haldex Hydraulics, Bucher Hydraulics, Dewald Fluid Power, HWH Systems, Kwikee, and Hydrotech Systems. Customers are sending the complete hydraulic unit to the Winchester, KY plant for diagnosis and repair. Although this operation is still in the startup mode, the identification of pump motors, electrical circuit boards, valves, manifolds, motor relays, and technical information manuals will provide a much needed service to the RV dealers and RV repair operations.

Repair for Kwikee Hydraulic Lift System Level Best call 1.800.779.5544

Reservoir, Manifold, and Logic controller for a Level Best leveling sytem shown in picture. Designed for use on a recreational motor home vehicle. The Kwikee Company of Oregon provided a complete vehicle automatic or manual leveling system. This system was widely used by several RV manufacturers on the West Coast, including Winnebago and National RV. Custom Cylinders International Inc. produced all of the hydraulic cylinders for Kwikee that were used in the Level Best product line. Since Kwikee was sold to Power Gear Company, CCI has been providing repair service, hydraulic manifolds, solenoids, leveling cylinders, and other components to the dealers and individual owners of Kwikee products. The system is a very reliable design, and to date CCI has been able to make satisfactory repairs on all units shipped to the CCI repair facility.

This leveling cylinder design and variations have been used by Equalizer Systems, Sooner Horse Trailers, Sundowner Trailers, and a portable stage manufacturer of California. The strokes vary from 11" to 36", and the bore sizes range from 2 1/2" to 3 1/2". In addition to repairing CCI designs, the RV repair department has repaired several other leveling cylinders manufacturers' designs.

United Technologies Automotive 12V Motor
12 volt motor W8055 SLOVENIA

The United Technologies Automotive 12V motor is the original manufacturer used in the prototype and early production of Fleetwood's recreational vehicle product lines. When the Taylor - Newcomb company put this motor design into the various Fleetwood travel trailer and motor homes, it was considered as a very reliable 12V motor. The best identifying characteristic used to identify this design is the casting on the shaft end shows "SLOVENIA" molded into the face. The United Technologies Automotive Company was sold to a company in Chicago, and a few years later was sold to a company in China. The design was changed, and replacement units were no longer available. 

When Hydra Slide wen out of business, Custom Cylinders International Inc. began to repair and replace many of the electrical and hydraulic components through our repair operation. A new source was found for many of the obsolete original components of the travel trailer and motor home hydraulic and slide out systems. The 12V pump motor for the Hydra Slide hydraulic system is now available at CCI by rebuilding the customers motor through the repair remanufacturing department, or by purchasing a new unit now being produced in the USA.
