減速してからの加速レスポンス向上   ベアリング厚さ3mm ベアリングシート1mm×2枚  計5mmの3点セットの商品です画像1

セカンダリスライディングシーブのガイド溝が斜めに傾いています

斜めのガイド溝のためセンタースプリングが捻(ひね)られて圧縮されます

ベアリングを入れることによりスプリングの捻りを戻そうとする反力を0にし溝とピンの動作をよりスムーズにします

減速するとセカンダリスライディングシーブが素早く低速側へ戻るため加速レスポンスが向上します

セカンダリスライディングシーブと共にスラストベアリング自体も同回転しますがベアリング内の<軸受コロ>はほんの少ししか回転しないのでグリースや油分を付けずパーツクリーナーで洗浄しただけのほうがレスポンス向上になります(油分を付けるとレスポンスがわるくなります)レスポンス=アクセルグリップ開に対する瞬時加速反応時間


シーブのオイルシール機能が失われたものはゴミほこりが入り、溝が摩耗し(画像5)低速側への戻りが困難になります 溝が摩耗したものはシーブを交換したほうが良いです (摩耗したところにピンが引っ掛かり戻らない=トップギアからローギアに戻らない=加速不良)


JOG へ使用するには画像6のセカンダリスプリングシート下部外側のつばをサンダーで取り去ってください(画像 7)

他にJOGセカンダリスプリングシートのツバを取り去る加工も出品しています そこで取り去り方法も紹介しています


シートの外し方
セカンダリスライディングシーブとセカンダリスプリングシート下部の間に小マイナスドライバー(百均小ドライバーセット)の先端をサンダーで薄く削ったものを四方から順に軽く叩き入れてシーブからシートを外します(画像5)


画像2、3、4、6のセカンダリスプリングシートは外側のつばが付いている状態で撮影しました

ついでにシート内のグリースE も交換したほうがよいです (グリースE も出品しています)


画像4のセカンダリスライディングシーブとベアリングシートの接触面をセカンダリスライディングシーブのテーパーに合わせてベアリングシートの1枚をテーパーサンダー加工すると収まりがよくなります(画像5)

 JOGはテーパー加工有りが良いです 



ベアリング及びベアリングシートの内径はφ45です  3KJのセカンダリスプリングシートの外径はφ43.5 径で1.5mm小さいですが問題なく使用しています

3KJの他φ45の機種のセカンダリスプリングシートにも使用できます
φ45.1以上の(シグナス系等)には使用できません


分解したついでに
ボス(クランク軸に付くパイプ状のもの)とプライマリスライディングシーブの摺動をなめらかにして加速不良の予防をします

上記互いの摺動面をサンドペーパー(#2000位)に油を付けて磨きパーツクリーナーで洗浄した後、きれいなウエス(百均ペーパータオル)で拭き(磨き)ます

互いの摺動面のオイル使用NG、オイルを塗ると次第に固着が始まり摺動せず加速不良(初期は段付き加速)→次第に登攀力不足になります

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). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
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. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. 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 .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.

※ Note: Photos provided to sellers should not contain any foreign-related information.
