ウォーターポンプのインペラは純正も随分と高騰してます。
そこでリプレース用にアルミ製のインペラが割と安く入手できるようになってきました。

ついでに冷却効率もアップ。
注意が必要なのは、プラスチックでできた純正ギヤだと負荷が増大するので強度的に心配が出ます。
そのため削りだしのアルミ製に変更する。
負荷が増えるのは、水を速く回す=インペラが受ける水の抵抗が増えるわけです。
これはエンジンの回転増減を受けて早くなったり遅くなったり。
で、プラスチック製のギヤを介して動かしてるわけだから・・・・とここまで書けばわかりますね。一番弱いギヤにしわ寄せが行くんです。

なので、このようにアルミギヤとセットで販売することにしました。
(単品は別途販売してますがセット使用は必須といっていいです)

NCで削り出したアルミのインペラとギヤ。
アルミはアルマイトかけてあります。
シャフトはステンレス製。
冷却効率は最大で35%アップ。

こういうところのステンレスは理にかなってますよね。
接触してるのはインペラとギヤだけだから電食もあまり気にしなくていい。
着色アルマイトの色抜けを気にする方がいますが、紫外線の影響を受けない場所で使用していればおきません。
むろん、削れてしまえば別ですが、その場合は何色でも同じですね。

そしてドレンボルト付きのアルマイト仕上のカバー。
まず、錆ない。そしてRZで冷却水を抜くときはここにドレンがあるといい。
水回りで一番低い位置ですからね。

ベアリングは互換品ですが信頼のNTNまたはNSKをセットして出します。(ベアリング銘柄は選択不可です)
オイルシールは純正です。

さらに、本セットはオイルシールやベアリング等々もまとめて。
ウォーターポンプ周りをフルリフレッシュするにはピッタリだと思います。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters).

3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4.

Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
