Hi everyone..on the subject of heat build up..do the bevel gearboxes on the Imp4ct get hot under normal running conditions.

I wonder because the bevel gears are in a small box with no air getting to them for cooling..I imagine the bearings would get quite hot..have there been any failures due to heat build up with these gear boxes..?

Thanks J

Hey Johners,

There hasn't been any heat issues. One has to make sure there is grease in those bevel gears.

Hi Johners,

As Marcel already sayed, lubrication is important and in 99% of the cases the source of heat building.
So, some maintenace from time to time is really necessary.
If you open the grear box it is verry easy to take out the gears.
With removed gears you will have a good view on the both bearings ( axial and radial bearing)
Be sure there is enough grease between the balls and rollers of both bearings.
When you rebuild the gear box be sure that the back of the gears is against the rollers of the axial bearings.
Put some extra grease on the teeth of the gears but don't fill the box 100% with grease.
40% filling of the gearbox should be sufficient.
For the details how the gearbox is build, i like to advice to look at the manual of the Imp4ct.

http://www.elcon-models.com/nl/imp4ct-4 ... order.html
The manual can be found under the tab "Downloads".
Here you will find the exploded views of both boxes.

If you have finnished the rebuilding of the gearbox it have to run easely and smoothly without any heavy points.

Best Regards,
Jan
