Cheap parts - why do I never learn?

UK Tech on Sun June 13, 2004 2:26 PM User is offline

Year: 1994
Make: Toyota
Model: Land Cruiser
Engine Size: 4.2TD
Refrigerant Type: 134
Ambient Temp: 25*
Country of Origin: United Kingdom

The blower motor is sqeaking and occasionally jams. So a new one from Toyota is £180, or a motor from 4S is £29.

Despite looking the same, I find out when fitting that the blower wheel stands too high on the new motor, so I have to 'modifiy' the inside of the blower housing to clear the wheel. Of course there's no proper plug on the new one either, so I have to splice the wires. It's also noisier in operation, and doesn't blow as much air. I did a bit of offroading today, and could hear something banging from the new blower, so when I get home I realise that the blower wheel and shaft have got a lot of end float, so the whole lot bangs up and down over bumps.

What a bargain that was!

Seimens makes a decent replacement, least for a Honda, but what is a guy going to do when the Honda dealer wants, $256.00 for a replacement motor? That is crazy, I got a Siemans for $40.00, and it fit like a glove, even drew the same amount of current as the OE and the air blast felt about the same. How does 4S stay in business?

Furthermore, if it's a Nippondenso motor, it should have screws, these are easy opened, I have taken these apart loaded with dead debris that was jamming the armature and a dog to work off the end plate as the shaft was rusty. would wire brush as much of that off and polish the shaft under the bearing, grease the entire shaft and load the wick with a synthetic oil that doesn't dry up as quick.

If the commutators are worn, I turn those on my lath with a diamond tipped bit for that purpose, and I use 1986 Nissan starter brushes that I mill to size cutting off the extra strands of brush lead wire closer to the original size, you need a high copper content brush. To save 250 bucks, I don't mind spending a couple of hours. I adjust the spring tension so the brushes make good contact, but not to the point where they grind into the commutators, that wears them out quick. The case has permanent magnets so just a good cleaning, but you could put a coat of paint on it if you like.
