Product complete description (H1: short short aluminum hub Ø17 mm - complete CRG Mini)
The short front hub CRG 17 mm high precision aluminum is a part of the manufacturer origin (Original CRG Share), specially developed for the chassis of the range Mini (Mini 60, minimal, cadet) of the group CRG (CRG, Maranello, Dr. Kart).
The "short" version of this hub is an essential setting piece to refine the behavior of your front train. By reducing the contact and clamping surface on the rocket, this hub brings a greater mechanical flexibility by the front train, offering the young driver a brighter direction, a more incisive train and better registration in tight turns. CNC machined in a high quality aluminum block, it guarantees maximum strength for minimal weight.
Specificities of the "complete" model:
The hub is delivered mounted and includes:
-
The short hub body high performance aluminum.
-
2 high precision waterproof bearings (Inner diameter of 17 mm) already inserted.
-
The internal spacer calibrated for perfect alignment between the two bearings.
-
Fixing studs to receive the rim before.
- 3. Tip in Michel (the corner of the expert)
* "Hi young champions and mechanos! This short hub of 17 is the piece to have in its toolbox when the track begins to have a bad grip and that the kart tends to saturate or refuse to turn in the tight.
My trick for mounting at the top: clean your rocket axis to the brake cleanser before putting the new hub. Then apply a very fine lubricant film type WD40 or a very fluid fat. It avoids that the bearings do not lock by electrolysis or with moisture on the rocket axis.
And when you tighten your rocket nut, make sure that the hub keeps a totally free rotation. If there is any hard point or if it stops instantly when you launch it by hand, it is that your spacing rings force too much on the shoulder of the bearing. We want the perfect freewheel to release horses in straight lines! "*
- 4. The mounting guide & setting: step by step
1.Demontage of the wheel:3 min.Place the kart on its track trolley. Unscrew the 3 front wheel nuts and remove the rim. Then unscrew the safety nut (often puffed) at the end of the axis of your 17 mm rocket.
2.Nettoyage and inspection:2 min.Remove the old hub as well as the track spacing rings. Pass a degreaser on the rocket axis to remove brake pad dust and gum residues.
3.Ajustement from the front way:5 min.Arrange your spacing rings on the axis according to the desired front channel width. Apply the trick to Michel (light lubrication), then slide the new complete hub CRG on the rocket.
4.sert and sinking:3 min.Replace the thrust washer and the rocket nut. Tighten the nut firmly while making sure the hub is ultra-fluid. Do not forget to put the safety pin back on the rocket nut before moving up your rim.
❓ 5. FAQ SEO (Frequently Asked Questions)
Q: What is the difference in behavior between this short front hub and a long hub ?
A: The short hub gives more flexibility to the rocket, which releases the front train and makes the kart more agile and responsive when the turn trigger. The long hub, as for it, rigidifies the axis, which brings more stability in large fast curves but can make the kart heavier to register in tight pins.
Q: this hub CRG does it adapt on rims of other brands (eg OTK, AMV) ?
A: Yes I do. In the rim drilling, this hub respects the standard 3-hole standard distance (3x58 mm). So you can ride any standard front rim on the market. Just make sure your rockets are 17 mm in diameter (the mini / cadet category standard).
Q: Are the internal bearings waterproof ?
A: Yes, the bearings integrated with this complete hub are equipped with waterproof protection flanges (2rs) to prevent the track dust, sand or moisture from infiltrating into the beads, thus guaranteeing excellent longevity.
