Instructions

General:

• Before every ride, make sure that your tune product is in a good condition and functioning properly. If there

seems to be any irregularities the product should not be used. Contact your retailer for help.

• The Quickrelease must be mounted properly.

• Never clean your Tune products directly with high water pressure (pressure cleaner) and do not use ag-

gressive detergents.

• Only use tires that suit the rim, pay attention not to exceed the maximum tire pressure of the rim and tire.

Maintenance:

The hub should be maintained at least once a year. If used in extreme conditions (rain, mud, salted streets,

transport in the rain) regularly, the hub should be maintained more often. A regular service supports the tech-

nical condition, as well as the durability of the hub.

What does the regular maintenance include?

• The mounted hub should be cleaned. Afterwards it should be undertaken a detailed visual and technical

examination.

• When disassembled, the bearings should be examined. The maintenance is described in detail below.

Lacing:

• The hub is constructed for radial lacing or crossed lacing.

• The 32 and 36 hole version has to be laced crossed.

• If the MIG70 hub is gets laced radially the spoke heads have to face outwards.

• The MIG 70 anges have been designed to automatically distribute the tension among the spokes evenly

during the lacing process. There will be no more movement, of the anges relative to each other, once the

spokes all have been tensioned (exerting an overall pulling force of several tons).

MIG70:

The highest permitted spoke tension is 1000 N.

Maintenance

Construction of the hub:

This hub is built up from rmly connected parts, i.e. the axle goes all the way through, with endcaps at

both sides, and all parts are xed exactly in place.

Tune uses specic bearings not available from any other manufacturer. The bearings distinguish

themselves by there unusual high amount of special grease and a radial play adjusted for the use.

The bearings have a double slid sealing, the hub therefore will run comparatively sluggishly when

new. This will change after the rst rides, when the grease has been dispersed evenly in the ball-bear-

ings and the seals are working optimally.

Spare parts can be ordered through your local Tune retailer.

g.1

Disassembly and assembly of the hub:

Important notes:

• All contact surfaces, except between the bearings and the hub body, should be greased.

• Always remember the exact position of all parts.

• Please contact your dealer, if you feel insecure, don´t have appropriate skills or the needed

equipment.

Needed tools / material:

• tool kit Tune Tool 08 (No. BWZ0000)

• plastic hammer

• an rob (old Quickrelease axle)

• hot air blower

• vernier caliper

• 1Grease (we recommend Molykote Rapid Plus Paste, alternative bearing grease)

• 2Glue (e.g. 3M Scotch-Weld TL-70, Loctite 641)

This manual leads you through the complete disassembly, assembly and adjustment of the hub. Not all

steps have to be carried out maintaining the hub.

If you only want to adjust the bearing play you can start with the rst step „Removing the endcap“ after-

wards you can continue with the step „Setting the bearing play“.

The hub gets placed on the main tool TT08.1.

An Quickrelease axle gets pushed through the

left endcap into the hub axle, so that it touches

the inner side of the right endcap.

The right end cap can now be pushed of the

axle by hitting the Quickrelease with the plastic

hammer.

Be careful to not loose the distances, which

are placed between the endcap and bearing.

Needed tools:

• plastic hammer

• old Quickrelease axle

• main tool TT08.1

If the hub is not laced, the ange (including the

pressed-in bearings) as-well as the inner sleeve

can be separated already.

Needed tools:

Release axle and bearings

Place the hub on the main tool with the extra attach-

ment TT08.9, that only the left endcap touches the tool.

Using the tool TT08.5 and a plastic hammer hit the axle

softly. g.11 By doing so, strain is taken of the axle

and the bearings.

g.11

The axle gets slightly covered with grease 1 in the

contact areas. g.10

The hub gets placed on the main tool TT08.1. Using

the tool TT08.5 and a plastic hammer the axle gets

pushed back into the hub. g.9

g.12

Needed tools:

• TT08.1 No. WZ0200

• TT08.9 No. WZ0204

• plastic hammer

• vernier caliper

• grease 1

Now the open end of the axle on the right side has to be meas-

ured. With the depth gauge of a vernier caliper measure the

axle from the inner ring of the bearing to the end of the axle.

The measurement has to be extremely precise, we recom-

mend to repeat the measurement a couple of times. g.12

TT08.1TT08.9

Reasons for bearing play can be worn bearings, a damaged axle or just the adjustment. A certain bearing

play is normal and enables a soft and smooth rotation.

The axial bearing play is adjusted with washers. These are available in 0,1mm (NZ1604), 0,15mm (NZ1605)

and 0,2mm (NZ1606) width. The washers are placed between the outer freewheel bearing and the right

endcap. We adjust the bearing play during production for every hub in manual labour. With wear, or when

new bearings are installed, the bearing play has to be readjusted.

7Setting the bearing play

g.14

From the measured length (e.g.: 8.4 mm) subtract the

depth of the endcap (8.0 mm). The difference is the axial

bearing play (here 8.4 - 8.0 = 0.4 mm).

The optimal axial bearing play amounts 0.15-0.20mm. The

difference between the measured open end of the axle

(e.g.: 8.4 mm) and the depth of the endcap (8,0 mm) has

to be adjusted to 0.15-0.20 mm using washers. g.13

The axial bearing play is adjusted perfectly, if the length, of

the open end of the axle, with washers is set to 8.15-8.20mm.

To nish of, the endcap is slightly covered with grease 1

on the inside. Now it can be pushed back on using a plastic

hammer. g.14

Now the wheel is usable again.
