40A  Marine gearbox manufacturer,high quality,competive price and best service.

Marine Gearbox Model 40A can perform the duties of ahead and astern, engaging and disengaging as well as reduction of speed, with a rated transmission capacity of 0.0294kw/rpm. It can be coupled with various marine diesel engines of equivalent torque(e.g. the type of 695,4100,6100,2E105,3110,4110,X4105C,495C,X6105C,4115 Marine Diesel Engine) so as to form a complete marine power unit, which is suitable for small boats navigating in inland rivers or in coasts.

This gearbox is characterized by compact construction, instant response for operation, and it is hydraulically controlled easy to be operated from the bridge with remote control.

There are two type of input structure of the said gearbox: flexible pin-type coupling or rubber toothed block coupling. One is with bell housing whereas another is without. And there is a match coupling at output end of the said gearbox. The rubber toothed coupling or the bell housing or the match coupling are available for our customer on request. Otherwise, type delivered only will be flexible pin-type coupling.

1. Only specified lubricating oil can be used, and the oil must be kept clean.

2. During normal reversing, at first ensuing speed should be reduced, and let the control button remain at "STOP" position for 2-3 seconds before shifting to the opposite rotation direction of gearbox output shaft. After reversing to the required rotation direction, then, speed up the engine.

3. Under the conditions of the rated speed of the gearbox and the oil temperature at 45-65, the hydraulic pressure is 1-1.2Mpa(10-12kgf/cm*cm)

4. Oil seals, arranged at the rear ends of input shaft and secondary shaft, of which the outside diameter is to be fitted for the bore of bearing covers, are to be placed in oil seal grooves of the shaft after tightening the lock nut at bearing rear end. Bearing covers are then capped carefully and fixed by bolts.

5. Please study carefully the said Manual and the Tech. Information on Q06 Hydraulic Control System so as to operate the gearbox smoothly and reliably.

6. When ordering, please quote the spare parts in accordance with the Manual and the Tech. Information on Q06 Hydraulic Control System.

Power/speed(kw/rpm):22.5/750-60/2000
