Yanmar JH-CR 45/57 adapter plate

This plate serves as a high-precision mechanical support to mount the Integrel high-power generator on your marine engine. It ensures a solid structural connection and perfect alignment between the engine block and the power generation system.

Universal mounts are often prone to vibrations and misalignment. This plate is specifically machined for your engine’s mounting points, ensuring perfect belt geometry and preventing bearing damage under stress.

The plate is supplied ready to be mounted on the designated mounting points of the engine block. The specific fasteners required to assemble the bracket on the engine are usually included in the overall installation kit for the Integrel system.

Yes, the Integrel adapter plate is made from robust materials and has a surface treatment designed to withstand marine salt environments and the high temperatures of the engine compartment.

The plate itself does not require any specific maintenance. However, it is strongly recommended to visually check its condition and to verify the tightness of the bolts during the annual service of your marine engine.

This precision mechanical part is manufactured in the United Kingdom. It meets strict engineering standards to withstand the very high torques generated by the Integrel system during battery charging.

No, this plate is machined exclusively to fit Yanmar JH-CR models with 45 and 57 horsepower (common-rail technology). It will not fit other series or power outputs from the same brand.

This plate is specifically designed to withstand the mechanical stresses and very high torque of the Integrel system generator. It is not intended or sized for mounting a standard replacement alternator.

No, the mounting points and engine block geometry differ on older models. This plate is strictly reserved for recent JH-CR (Common Rail) versions in 45 and 57 hp.

No structural modification of the engine block is required. The adapter plate is custom-designed to mount directly onto the original mounting points provided by the Yanmar manufacturer.

Yes, the plate is mounted on the front of the engine block for belt-driven transmission. The type of your boat's stern drive (Saildrive or conventional shaft line) does not affect the compatibility of this part.

The installation requires excellent marine mechanical skills. You must ensure the exact torque and perfect alignment of the pulleys. The intervention of a certified professional is strongly recommended to secure the installation.

Incorrect alignment of the plate will cause premature wear on the drive belt, excessive vibrations, and may apply destructive asymmetric loads on the engine and generator bearings.

Installation requires standard mechanical tools of good quality, including a torque wrench to respect recommended tightening torques, as well as alignment control tools for the drive belt.

Yes, adding the plate and the Integrel generator increases the footprint on the front and side of the engine. It is crucial to check the available space in your engine compartment before proceeding with the installation.

Mounting the plate itself is relatively quick for a qualified technician. However, it is part of the overall Integrel system installation process, which requires several hours of meticulous work.

Generally speaking, no. Installation can be done with the engine in place, provided there is enough space in the bilge to comfortably access the front of the Yanmar block and use tightening tools.

The high-precision machining of the plate ensures a default geometric alignment. However, this alignment should be checked using a specific laser tool during the final tensioning of the belt.

Yes, it is imperative to respect the torque values defined in the Integrel installation manual. Inadequate tightening could cause dangerous vibrations or damage the engine block threading.

It is possible to paint the plate to match the gray color of your Yanmar engine. However, you must ensure that you never paint the contact surfaces, threads, or bearing areas of the generator to maintain perfect alignment.
