CA6110 engine 129 / 148 Teeth Flywheel Gear Ring for DEGONG XGMA CHENGGONG 30 wheel loader

There are two reasons for the idling sound of the drive Gear and the engine flywheel ring gear when the starter starts:

Folding deformation
Because the multi-cylinder engine often stops in the cylinder with the largest compression force when it is turned off, the impact position of the flywheel ring gear is roughly the same every time it starts, and the cutting surface of the ring gear is deformed over time. In this case, you can turn the flywheel ring gear to an angle or turn it back and forth and re-install it. Under normal circumstances, if you can’t start at one time, you must wait for the gear to return to the original static position before doing the second time. Start.

Folding gap is too large
(The axial distance between gear and ring gear should be kept 2.5-5 mm).

In this way, when the main circuit is connected, the starter gear and the flywheel ring gear are rotating at high speed without meshing. When the two contact, they will naturally make a noise due to the impact, and the two cannot mesh, and the engine cannot be started. In case of this failure, the gap between the static and moving contacts of the starter electromagnetic switch can be increased; padding between the electromagnetic switch and the starter rear shell; eliminate the redundant gap of the support pin in the middle of the starter fork; replace the wear on the fork Decrease the slider or pulley; when installing the ring gear on the flywheel, do not press the ring gear to the bottom of the flywheel, leave a gap of 2-3 mm or choose a thicker ring gear to eliminate it. In addition, the overall length of the starter drive gears sold on the market does not meet the standard, and the height of the flywheel and ring gear produced by some non-standard factories does not meet the standard. This is easy to cause this phenomenon. Please be careful not to be cheap when buying And cause greater losses.
