This version has a reduction ratio of 1.54:1 in both forward and reverse and is equipped with an output shaft at an 8\u00b0 angle. The reverse gear is used to transfer engine power to the propeller shaft in a controlled way and enables shifting between forward, neutral and reverse.<\/p>\n<p>Thanks to its hydraulic operation, the TM345A is designed for smooth shifting and reliable operation under load. Thanks to the 8\u00b0 output shaft angle, this version is suitable for installations where an angled arrangement in the drive line is required. Always check whether the reduction ratio, maximum permitted torque, shaft angle, installation dimensions and connection match the existing engine and propeller shaft installation.<\/p>\n<h4>Application<\/h4>\n<p>This Technodrive reverse gear is used in inboard drive systems where the engine drives the propeller shaft via a reverse gear. The transmission provides the correct reduction of engine speed and makes it possible to change the rotation direction of the propeller shaft. The 8\u00b0 output shaft angle also makes this version suitable for marine installations where the drive line must be mounted at an angle.<\/p>\n<h4>Main features<\/h4>\n<ul>\n<li><strong>Hydraulic operation:<\/strong> Ensures smooth shifting and reliable power transmission.<\/li>\n<li><strong>Forward reduction 1.54:1:<\/strong> Suitable for installations where this transmission ratio is required.<\/li>\n<li><strong>Reverse reduction 1.54:1:<\/strong> Equal reduction in both directions of travel.<\/li>\n<li><strong>Output shaft angle 8\u00b0:<\/strong> Suitable for installations with an angled drive line arrangement.<\/li>\n<li><strong>Maximum input speed 4,500 rpm:<\/strong> For suitable engine installations within this speed limit.<\/li>\n<li><strong>Oil capacity 1.5 litres:<\/strong> Supports lubrication and cooling of the internal components.<\/li>\n<li><strong>Lubrication pressure 0.5-1.5 bar:<\/strong> For reliable lubrication of the reverse gear.<\/li>\n<li><strong>Operating pressure 24 bar:<\/strong> Designed for hydraulic operation under load.<\/li>\n<li><strong>Dry weight 25 kg:<\/strong> Compact version for marine drive systems.<\/li>\n<\/ul>\n<h4>Technical specifications<\/h4>\n<ul>\n<li><strong>Brand:<\/strong> Technodrive<\/li>\n<li><strong>Type:<\/strong> TM345A<\/li>\n<li><strong>Article number:<\/strong> TM345A154<\/li>\n<li><strong>EAN number:<\/strong> 8719182620082<\/li>\n<li><strong>Forward reduction:<\/strong> R=1.54:1<\/li>\n<li><strong>Reverse reduction:<\/strong> R=1.54:1<\/li>\n<li><strong>Maximum input speed:<\/strong> 4,500 rpm<\/li>\n<li><strong>Dry weight:<\/strong> 25 kg<\/li>\n<li><strong>Oil capacity:<\/strong> 1.5 litres<\/li>\n<li><strong>Output shaft angle:<\/strong> 8\u00b0<\/li>\n<li><strong>Lubrication pressure:<\/strong> 0.5-1.5 bar<\/li>\n<li><strong>Operating pressure:<\/strong> 24 bar<\/li>\n<li><strong>Maximum torque pleasure craft:<\/strong> 25 kgm<\/li>\n<\/ul>\n<h4>Why the correct reverse gear is important<\/h4>\n<p>A reverse gear is an essential part of the drive line. An incorrectly selected, worn or poorly fitting reverse gear can cause slipping, poor shifting, vibrations, heat build-up or damage to the engine, coupling and propeller shaft installation. That is why it is important to carefully check the specifications of the existing installation before replacing the reverse gear.<\/p>\n<h4>Scope of delivery<\/h4>\n<p>The delivery consists of one Technodrive hydraulic reverse gear TM345A with a reduction ratio of 1.54:1 and an output shaft angle of 8\u00b0. Before installation, always check the technical drawing, connection dimensions, shaft angle, rotation direction and specifications of the existing installation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Technodrive TM345A154 is a hydraulic reverse gear for inboard drives with a reduction ratio of 1.54:1 in forward and reverse.
