Gasa XM 2.1 "Prestige"

Are all the pulleys aligned and the belt tension correct.

..if I checked everything, the belt is tight, it's not loose enough to slip, it's simply a bad belt.

...small intervention on the oil filter housing. In the last few days, it happens that when the engine is first started in the morning, it runs for 3-4 seconds and shuts off, after that it won't start, despite several attempts, until I manually pump oil into it.
On various forums, I find that the problem is in the filter housing, that it leaks oil on the tremostat, O ring rubber. This was also the case with my filter housing, so I immediately started solving the problem.

..the problem is in this rounded part, when the other oil starts to leak from the pump, when the engine starts, then in that place it starts to draw air into the system and has a restless operation.

....the filter cartridge is pulled out, the excess oil is removed with a syringe, and with a gedor No. 13, it is removed from the engine.

...one by one the holder is released slowly.

..in the end it breaks free, pulls out the entire thermostat.

.. rubbers are easy to change and everything goes back to its place, it's a little harder to go back because of the new rubber, you have to take care not to get hurt.

...the fuse is returned with a gedor 13 in order to press it evenly and strengthen it.

This morning,the engine started at first and runs smoothly, nothing complicated to do, but the real big problem,the cost of replacing the tire is 0.8 eu

Nice fix and write up there, Gasa.

80 cents sounds like a lot though...

[Gasa]

..yes, the price is very high.
last year, I saw a picture on a forum that someone had installed an electric pump, I asked why the pump was installed, the answer was that some Austrian craftsmen did not know how to remove the defect that was on the filter housing, and that they have now done all that and removed that electric pump, I didn't ask anything further, but the conclusion was that this particular problem with the O ring rubber was...

The steering wheel was finished today, it was for upholstery, I don't like this plastic one, everything slides through my hands, so I got a leather one that needed to be fixed, so today I replaced it too.

..plastic.

Of course, the controls are not functional and the buttons are just a decoration.

In the last month, I noticed that the heating is not working properly, or it keeps blowing cold or hot, I removed the motor for moving the damper, took it apart, put it back and looked at everything correctly, not a single gear was broken, the damper arm moves slowly, after dismantling the motor everything works fine for a day or two and freezes again and nothing works. The motor, the potentiometer, the board was not damaged anywhere, I thought that the control panel for the air conditioning had failed, I planned to change it.
After looking for the possible cause of the failure of the heating on a website, I came across the same problem as mine, the problem was in the brushes on the motor, and I opened it to check the brushes, they look great, they are not worn.
The problem is that the brushes have become rounded and are not flat, but their contact surface on the rotor has increased and sometimes they catch two collectors and there is a short circuit, which is why the command to cool or heat is canceled, it does not respond to any command. The problem was solved in 5 minutes, I sanded the brushes with tweezers and sandpaper and gave them a bit of a conical fit on the rotor, it's been working as it should for a week now, I test it every day, hot, cold and some temperature in between, so far everything works great

..on the brown and black wire there is current for hot-cold in which direction the engine should turn the valve, this was tested on the connector from the engine, it happens that there is current on both wires, it should not be like that, but it depends on only one of them which command is given, when it happens that there is current on both wires, it means that the brush has connected two collectors and the engine remains stuck, that is the reason for the cancellation

IMG_20240315_173552.jpg

.this is the incoming connector from the heating control, and there is always current on the wire to which the command is assigned, when it is inserted into the connector on the motor, current appears in two places, which means that the motor, the brushes are then connected

..brushes slightly scraped.

...and cleaned channels on the collector

.this slot serves to spread the brushes and to return the motor to the brush holder.
