Frequently Asked Questions
We sell most wheel motor parts to Husqvarna and Gardena. We offer complete repair kits suitable for the most common motors. For the older machines, we stock most things such as plastic and steel gears, washers, pins and wheel bearings. Repair kits for front wheels and lock washers in stainless steel are also in stock. At Klipparservice you will simply find most things, the question is probably rather what we do not have when it comes to wheel motor parts! 😊
The ambition is to always send the spare parts as quickly as possible. Orders placed before 22.00 are usually posted the following day. Customer service is a high priority as we know that the mower would ideally have been repaired yesterday. 😊
Yes, on the "Tutorial" page you will find everything you need to succeed with your repair. There is both a YouTube clip and an PDF instruction.
If the machine has been running for more than 5000 hours, it is very likely that the motors need to be rebuilt. To avoid consequential damage to more gears, it is a good idea to replace them before it cogs over completely.
Symptoms of worn-out gears:
• The motor sounds abnormally while driving and it sounds like the motor is cogging over.
• The machine turns uncontrollably.
• The machine cannot find its way home to the charging station along the guide wire.
• If the machine turns around more than normal.
A simple test to assess the condition of the wheel motor is to pull forward/backward in the wheel. A new wheel motor has a play of about 3mm measured on the outside of the wheel. If the measurement is about 10mm, the gearbox is worn and should be repaired. A large side play, larger than 5mm, also indicates poor wheel bearings. The best way to check the condition of the wheel motor is to disassemble it and inspect the gears.
Large motors (320,330X, 420, 430X, 440, 450X etc.)
In the large gearboxes, it is usually only the middle gear (sun wheel) that gets worn out in the outer part of the gearbox. Sometimes, the four planetary gears may also need to be replaced. This is usually due to broken teeth as they have been over-cogged for too long, but sometimes also because the holes in the middle of them have become too worn. Sometimes the plastic gears closest to the electric motor can have slightly enlarged holes, but this does not affect the durability. For good service life of your wheel motor, the wheel bearings also need to be replaced and the wheel axle attached with thread locking to them.
Small motors (105,305,310, 315, Gardena)
In the small motors, it is usually the outer layer with gears and planetary retaining pins that wears out. The pins get worn out and the holes in the three planetary gears become too large. In these small motors, the middle gear (sun wheel) can also wear out, usually as a result of poor wheel bearings. In some cases, even the helical plastic gears driven by the electric motor can break. For good service life of your wheel motor, the wheel bearings also need to be replaced and the wheel axle attached with thread locking to them.
Motors marked with Linix
These motors are of high quality and do not have the same serial defects as the other motros. The most common problem is that the plastic gears closest to the electric motor fail. Sometimes, the gears in the outer part closest to the wheel can also wear out. Wheel bearings seize and block the motor and this can lead to damage to the wheel axle. Even the planetary retaining pins of the wheel can break and block the rotation.
Motors marked with the Dunker motor (230, 260, 265ACX, early 330X)
These motors are also of high quality and if they are not neglected, they usually last a very long time. The most common problem is that the plastic gears closest to the electric motor fail. The steel gears, pins and ring wheel with internal teeth that enclose all planetary gears can also wear out.
Note! If you are going to open this type of motor, it is important to keep track of which gears have been installed where. Otherwise, there is a risk that gears will break when the machine is running again. This is because the gears are made of three different materials. Closest to the electric motor, the gears are made of plastic. The middle layer has sintered metal gears (rounded around the hole in the middle) and the outermost layer has steel gears (angular around the hole in the middle).

Generation 3 (310, 315, 320,330X, 420, 430X, 440, 450X)
If the motor is running but feels abnormally hard to turn, it's likely due to one of the following reasons:
- In rare cases, grease may have penetrated the electric motor and blocked the rotation of the motor. This can be repaired by unfolding the pressings that secure the end cap and tapping lightly on the motor shaft with a piece of wood. When the motor is opened, the grease residue can be cleaned out so that the motor can spin freely again. Then the end cap is reassembled and the pressings are knocked back in. This can happen on both large and small motors. In some cases, the grease in the gearbox may also dry so the gearbox runs heavily; This is more frequent for the small motors.
- Gear residue can block the rotation of the gears. On both large and small machines, gears can break of teeth and block the rotation completely or partially.
Generation 2 (220AC, 230ACX, 260ACX, 265ACX) also applies to 105/305
In these machines, the most common fault is that the main circuit board has been damaged by moisture. The easiest way to check this is to change the right and left wheel motor to see if the fault follows the motor. If the fault follows the motor, it can be verified that there is a fault with the motor. If, on the other hand, the fault persists on the same side, it is the main PCB that is defective.
What is the lifespan of the electric motors?
The electric motors are of very high quality. In my test machine (430X 2016) the electric motors have now been running 15000 hours and they show no signs of wear.
In my experience, it is only in isolated cases, below 1% that the electric motor fails. In cases where I have seen electric motors with bad bearings, the cause has been moisture damage.
What is the lifespan of the gearbox?
The gearboxes on the big machines tend to wear out somewhere between 5000 and 10000 hours. They can then be repaired with a repair kit. The same also applies to the smaller machines, but with slightly lower operating hours.

After repair with the method I show in the Youtu clip you can expect the durability to be at least as long as the original wheel motor, probably much longer. My test machine has been running 9000 hours after repair and the wear is non-existent.
The good thing about my repair method is that the wheel bearing is improved and the wear on this stops. This, in combination with high-quality gears and grease, means that the gearbox's weaknesses are eleminated.

Perform a test of the wheel motors in the Tools menu. See the procedure at the end of the Youtube clip as this is a hidden menu. The power consumption at full speed should not be much above 250mA. Check the power consumption again after the machine has been running for a day.
I am proud of my parts,and know that it is good quality and therefore have a 2 year warranty on my gears. This applies provided that you have been careful and followed the instructions in the Youtube clip. If you have done that, you will not have problems with durability for many years to come.
We service Husqvarna Automower and Gardena.
We make repairs in a short period of time as we know that it is important that the mower does not stand still longer than necessary. Expect about a week depending on the extent of the repair.
