Air-cooled 911 to be serviced again.

The other day, my husband took his air-cooled 911 (964) in for preventive maintenance again. This time, as in the last time, we asked a store in our neighborhood to do the maintenance.Mr. Beeforth.It is.

Nevertheless.As I recall, we had sent the air-cooling in for maintenance about two months ago, and now what more is there to do?I asked.

No, I don't have any major problems. I just want to do some preventive maintenance so that I can go on a long-distance grand touring trip anytime without any worries.
In this issue.Distributor belt replacement and strange noise from rear blower fanis sometimes heard, and I want to fix that.

My husband said. I see...

Maintenance parts for air-cooled 911

The air-cooled 911 took about a week to get serviced, and my husband had to pick it up again, but the servicing part ended up being

• Destributor belt, rotor, and cap replacement
• Replace fan and motor in rear blower fan
• Elimination of noise in driver's door
• Tension adjustment of belts

He said it was. "I mean, what is a distributor? What is a blower motor? What happens if I change it?I asked.

First of all, a distributor, or desbi for short, is a device that sends electricity to each cylinder at the right time in order to spark ignition in the engine.If the electricity generated is not sent to each cylinder at the correct time, the explosion will not occur properly in the engine.This is an important device since
In the case of the 964, there are two plugs (spark producing parts) for each cylinder because of the twin plugs. Therefore, theWe need to send electricity to 12 plugs at the right time in 6 cylinders x 2.That's why.
And the 964 has two distributors to match, so it looks like two distributors attached to each other.
There is a small belt that connects these distributors, and this belt is used for mutual ignition timing. If this belt deteriorates and breaks, the ignition timing will be off and the engine will lose power, or worse, the ignition will be at the wrong time.They say there are some things that can break an engine.

He explained to me. ...hmmm...I don't know the detailed structure of the car, so I kind of understood. He said, "I don't know the details of the car's structure.So you changed the belt because it was about to break?When I hear the word

No, it's not like it's about to go out or anything, but the maintenance record book shows that the entire distributor was replaced at 25,000km in 2001, but since then.I haven't changed it in 18 years and over 40,000 km, so I wanted to change it as preventive maintenance.No, it's not.
In fact, the belt was not so damaged, but the rotor and cap that distributes the electricity were worn out and needed to be replaced. (The belt was not damaged that much.(By the way, I heard that replacing the entire desbi would cost a lot more.)

I see. And what's a blower fan?" I asked.

I don't know what the official name is.Fan that sends heat from the engine to the heat exchanger to make the heater work.Recently, I sometimes hear a strange noise coming from here. I heard that it does not affect the driving, but it is not pleasant, so I had it replaced.
I heard that replacing the entire device would cost about 150,000 yen for parts alone nowadays, but this time I was able to get a cheaper price by using aftermarket parts for the motor and fan.

The total cost for this inspection and maintenance was about 199,000 yen for parts and labor. The company said the price was very reasonable. After the maintenance, the air-cooling system was even better, according to the customer.

I wonder if it's because I changed the rotor and cap on the Desbi.Engine pickup and extension improved.I have a feeling. Also.Fuel economy has improved tremendously.I haven't measured it properly yet, but I think it's about 10% different.
The caps and rotors were pretty black and worn before they were replaced, so maybe that's why they're new, so the electricity can be sent to each cylinder with less resistance.
It's really smooth, and the more I drive it, the more I think this air-cooled engine is getting better, but even smoother. I think it's a lot different than when I bought it.

He said. I've been reading a lot about maintenance costs and maintenance recently, but I think that a classic model Porsche like the 964 needs especially diligent maintenance.

Well, cars are expensive w
