General Information

PREPARATION

Its hydraulic command lever must be placed in a way of giving out sounds of crackling during forward, idle and backward manoeuvres. If hydraulic command lever does not place correctly, transmission mechanism can ooze. Also Electronic Command levers do not set correctly, there can be ooze problem on transmission mechanism. This subject is very important otherwise it may cause too much breakdowns.

OIL FILTER

Lubrication inIet is hoop of Iifting. The aeration hole is beside the hoop. Excessive lubricant can be removed through this hole. Lubricant deficiency causes transmissions mechanism to ooze or stop . Excessive lubricant is not harmful .

CLUTCHES
Clutchs system works by lubricant pressure (hydraulic system). Forward and backward clutchs systems’ plate numbers and sizes are same .

TRANSMISSION COUPLING
For coupling in transmission mechanism the sizes are mentioned in the own pages of every transmission mechanism. lt is not necessary for you to measure by uncoupling . Coupling is ‘keyed cone’ fitted to pin. lf it is not enough sequeezed there may be some dead space during forward and reverse maneouvers.

LUBRICATING

Lubrication inIet is hoop of Iifting. The aeration hole is beside the hoop. Excessive lubricant can be removed through this hole. Lubricant deficiency causes transmissions mechanism to ooze or stop . Excessive lubricant is not harmful .

HYDRAULIC PUMP
lt has gear system and is produced by Hema. lt transfers 12 Iitres oil for1 minute during 800 rpm/min. idle period. The bearings of the pump pins are shuttied. All connections from the transmission mechanism cranc to the pump should be sealed so as not take air. Thus some pressure Iowness occurs in the transmission mechanism.

COOLING SYSTEM
Cooling is accomplished by a cooler through and over which water and oiI can be passed . In this cooler there is pressurized oil. In long working period it can keep the gear not to be hot. Cooler can be worn and perforated owing to corrosion . In this case the oiI in the transmission mechanism will flow into the sea. The tubes of the cooler should not be cleaned with rigit tools. When the dirts passed through the filter, it stops up the cooler system holes and because ofthis transmission mecha

Frequently Asked Questions

Low pressure in the transmission due to lack of oil or other reasons causes the transmission to ooze. Due to poor adjustment of the spiral wire and its adjustment being disrupted by environmental conditions (such as heating and cooling), the spiral wire cannot fully pull the control lever. In addition, deterioration (wear) of the plates also causes the transmission to can ooze.

  • Lack of oil
  • Wear of O-rings
  • Wear of the pump after long periods of operation
  • Looseness of the suction hose
  • Clogged of filter
  • Rotated wedge bushes

Star coupling rubbers should be checked and damaged ones should be replaced. If the problem is not caused by the rubbers, the engine service should be contacted.

The clutch plates may be damaged. The plates should be checked and the damaged parts should be replaced.The piston springs should be checked for damage and replaced with new ones.The discharge channels may be clogged due to dirt that may form in the oil.
