Knocking when setting off on a used WHA 21 123 coupe have already been purchasing decisions. But as always was too lazy to pick up and disassemble a car that went bad in principle, moreover, that the sound (play) felt only when starting or sudden tightness during gear changes. But if after a gear change speed dial smoothly – everything was normal! Overflowed the cup, when I was in the garage (and I have it heated), dragged "nine". The poor car make havoc whole box, but its insides were visible outside – Housing (casing) box was broken down so that it fell off from a large piece of aluminum. After questioning the driver of the previous symptoms, I realized that I had a car it was all just like me. Poor box – it has survived for the assembly is only slightly more than half the parts. Differential gears, satellites and the finger on which they spin – everything had to be replaced. Repairs cost the owner very expensive! Realizing that I can also get into these situations and, throwing lazy, I began to disassemble the box its WHA 21 123 coupe, especially since these cars PPC device differs only slightly.

Having examined the box dvenashki, I, at first glance did not notice any visible defects – all the gears in the oil glistening, teeth were intact. But the sound of something still was! Deciding to go to the end, make out everything he could. And here's what I found the cause of knocking my boxes, and realized that the machine had the same problem. Finger differential, which revolve satellite, was a half-eaten, so that the satellites just dangling there. Material finger abrasion can say just vtersya the inner surface of the slip satellite. So apart from the finger, and had to buy a satellite. Complete with a finger, while they only cost about 400 rubles, while the box body (usually only one broken sump) – 2500 rubles. It was found that abrasion, finger breaks, pop up satellite and stuck between the crank and rotating the differential, which leads to a breakdown of the corps, with all its consequences. Now, raising the front wheel, I always check – does not increase if the free play wheel included in first gear backlash if more than 30 degrees, and continues to grow – it's time to disassemble the box!
