Citcop/Panasonic RC-1229PVXU / RA-1229PVXU air conditioner

Exchange of noisy fan motor in the indoor unit.
Remove screws (red circles) and 4 cables which are attached to a small PCB (blue circles). This is a small and straight forward job. Only a PZ1 screwdriver is required.

 Picture of RC-1229PVXU after I've removed the fan motor.



Picture of the fan motor.





After I changed to the new fan motor, I took the old one apart and changed the ball bearings.



Two ball bearings (yellow circles) were bad, which made the motor noisy. The ball bearings are type 608Z (axle 8mm./ diameter 22 mm. / 7 mm. wide)




Ball bearing type 608 Z. 608 ZZ can be used as well.

Mercedes E430 W210 M113.940, 205 kW 1999

Engine stalled randomly. Could be impossible to start for a longer period of time.

I had some difficulties with my E430 (W210) 1999.
When I tried starting the car the engine was not turning over. In fact nothing happened at all, except some kind of "humming noise" and the lights in the instruments came on. I could leave
it for a while and try again and it would start and runs like it should. After that it could start maybe 5 or 6 times and then fail again.

  • Battery was fully charged
  • I changed CPS (Kurbelwellensensor)
  • I changed K40 relay unit (A 000 540 00 72)
  • Removed and checked the ignition switch

The relay K40 (A 000 540 00 72) unit (yellow circle) was not closing when it had the starting issue. When it was starting, the relay was closing as well.



The fault was found in the ECU. It had a bad soldering point at the EEPROM (yellow circle).
ECU: Mercedes number: A 026 545 69 32. Bosch number: 0 261 206 303. The same ECU is used in other Mercedes, 8 cylinders as well. For ex. ML 430.



In case of replacing an ECU you have to keep in mind that the door lock (driver side), ignition switch and the ECU has to be paired together. It means, copying immobilizer data from the old ECU to the new one.



Rebuilding a kitchen


Old kitchen furnitures.


 Old kitchen furnitures removed





New electric cables, conduits (plastic tubes) and electric installation boxes installed.




Wooden beams inserted in between the old beams in order to strengthen the wall and to have strong points for fixing the new kitchen furnitures.






Rebuilding the walls with new plasterboards.





Using some plasterboard filler.





Installing stop valves onto the hot and cold water pipes.


Installing the new kitchen furnitures.







A new kitchen sink and water tap with all the pipes and tubes in place.


Tiling the walls above kitchen worktop and installing the kitchen fronts.





Just some coving, a new ceiling lamp, some door handles and knobs left :)

Vw T4 Multivan 2.5 AAF 81 kW 1994

Convert the VW T4 Multivan -94 with AAF motor and CRN automatic gearbox to AAF motor with CPV manual gearbox.

Parts to change:
Gearbox
Flywheel
Clutch pressure plate, friction plate and release bearing
Clutch wire
Clutch pedal and a smaller brake pedal
Gear stick with all the rods
Drive shaft. (different length on one side)
Starter motor
Motor bracket (at the rear left of the engine)
Gearbox bracket (at the rear right of gearbox)
Starter relay (need to be rewired)
New ECU software(the VW was idling too high (1700 RPM) after the the rebuilding)

Reprogrammed ECU EEProm.

The ECU in my VW T4 Multivan -94 automatic, was 023 906 022 J.
I used my Willem soft Eeprom programmer and software to write the software from a 023 906 022 B, ECU, to an empty 27C256 Eeprom.

Willem soft interface:


Willem soft Eeprom programmer:


If you open the BIN file in a hex-editor you will be able to read the version of the file from the address 0x2050 (yellow). The BIN file size is 32 kB.


27C256 Eeprom:

Rebuild the VW T4 Multivan to run on Etanol. I bought a DIY kit from Flexitune.se and soldered it together. The job was straight forward following the manual. All you need is a soldering iron and a multimeter.

Stiga 8 hp Briggs & Stratton snowblower

Snowblower was running without engine oil. Piston head got stucked and it was not possible to pull the starter any more. Completely jammed.

I removed:

  • Petrol tank (4 bolts)
  • Fuel line
  • Oil stick
  • Choke switch
  • Primer with cover
  • Exhaust protection and exhaust pipe
  • Accelerator switch and springs
  • Spark cap and spark plug
  • Cylinder top (4 bolts)
  • Belts for drive and blower from the drive shaft

I sprayed the WD-40 into the cylinder above the piston head and waited for a few minutes.
Then I took a big spanner and put it on the big nut on the drive shaft. I turned it slowly forth and back a few times since the piston head seemed to move again. Then I turned it all the way around a few times. I filled the engine with motor oil and pulled the starter 15-20 times. Then I used the electric starter a few times. Everything seemed to work like it should. The cylinder walls was ok as well. I putted it together, primed it and fired it up. I worked like it should.

Detach upper bolt from brake calliper
-counter hold using open-ended wrench
Detach the brake calliper from the brake carrier.
Suspend it from the rear spring with a suitable wire.

Take out brake pads and guide plates

Clean guides for brake pads in the top and bottom of the brake carrier and contact surfaces with brake pads on the brake piston and the opposing surfaces.

Note:   Make sure that residues of adhesive on the brake pad surfaces are removed and the surfaces cleaned afterwards.
