Product information "y0733 Big Scale-EXTREME, adjustable 3 - shoe clutch"

With the Big Scale-EXTREME an adjustable clutch for very special requirements has been designed:

For large-displacement engines
For heavy or high traction cars (Losi, HPI)
For modified performance engines
For the demanding off-road use

Rapid wear of a clutch is a sign of constant slipping, even beyond engagement speed. In this case, the clutch does not transfer the applied torque.

This is where the Big ScaleEXTREME sets a new standard.
The new design of the "Extreme" prevents the centrifugal forces of clutch springs or lever side of the clutch shoes from counteracting the centrifugal force of the friction pad side even after engagement.
As a result this clutch can transfer lots of power with minimal wear.

The new design ensures that the centrifugal forces are transferred in full to the clutch lining. Precise engagement and disengagement even under high loads and inside of closed clutch bell carriers means no problem for this clutch.

The clutch can be easily adjusted to the engagement speed through three set screws without clutch bell removal, so you can match the characteristics of your engine.

The special clutch lining of the Big Scale-EXTREME is particularly wear-resistant and - especially in combination with a high-quality nitrited clutch bell (), guarantees for an exceptionally long service life! Contrary to the "Cross" or "Race" version there's no need to uninstall the clutch from the engine for maintenance. All parts are easily accessible from the front after removing the front plate.

Please see the specifications tab for further information and handling advices!

The regular price of the Big Scale-EXTREME is EUR 139.90

Caution: It is very important that when swapping the full-aluminum clutch shoes against the organic friction pads of a Big Scale CROSS or RACE to use a different or new , because the rough surface of the aluminum deposits in the clutch bell left by the Big Scale ALLOY will cause a high wear on the organic pads.

y0743 Clutch-Safe 10 g, adhesive especially for clutch pads

Special single component epoxy adhesive for bonding clutch shoes; suitable for extreme operating temperatures (up to 200°C!) Important note for processing: For the final cure of the bond Clutch-Safe must be tempered at 170°C for 1 hour! (1 hour at 170°C in the oven!) The extremely high temperature load on the clutch shoes when used in off-road cars caused by increased clutch slippage, the shock of jumps and the combination with sometimes very high vehicle weights (up to 18 kg!) make bonding with Clutch-Safe highly recommended. For later removal/replacement of worn out clutch pads the clutch shoes must be heated as well.Attention:Clutch-Safe adhesive must be stored in the fridge! Content: 10g tube

The Gas-nitrited tuning clutch bell:Gas-nitrited tuning clutch bell machined from high grade steel with a hole for easy clutch adjustment. Special vents remove dirt and clutch lining debris automatically, preventing it from accumulating in the clutch bell and causing premature wear to clutch bell and linings. They aid in cooling of the clutch bell as well. The clutch bell features a significantly reinforced wearing surface and face which guarantees dimensional stability even under high loads! The shaft is a tiny bit longer than stock (about 0.2 mm) to prevent the bearings from binding. Since this clutch bell is single-piece machined from bar stock there is no weld bead on the inside of the face plate. The gained space allows now to use the adjustable GPM Big Scale-Cross clutch. Suitable for genuine slot drive HPI pinions. Comes with bolts and spring washers included.The GPM-Big Scale clutch:Suitable for racing and for the ambitious hobbyist driver. Unlike the stock clutch, the installed GPM-Big Scale clutch can be adjusted by turning one single screw. A 2.5 mm allen key wrench is required for this application.Therefore it is possible to precisely adjust the clutch engagement depending on track characteristics.Handling instructions for three-shoe clutches y0730 GPM Big Scale Cross and y0731 GPM Big Scale RaceInstallation:The GPM Big Scale clutch will be bolted to the crankshaft using the supplied CSH-screw.It should be noted that the use of thread locking compound on that screw is neither necessary nor recommended!Removal:Remove the CSH-screw with a 4mm Allen wrench; then insert a suitable M8 bolt and remove the clutch from the crankcase cone by tightening that bolt. Hole for adjustment:For clutch adjustment without removing the clutch bell a 4 4.5 mm hole must be drilled into the clutch bell for access to the adjustment screw. Placement of the hole depends on clutch bell dimensions and car; so you have to make your own measurements for the placement of the hole.It is important that the drilled hole is thoroughly deburred (at least on the inside of the clutch bell) to prevent excessive clutch pad wear. Breaking in:A new clutch or shoes fitted with new pad should always be broken in. Therefore the clutch engagement speed should not be too high for the first tank of fuel. This gives the lining the possibility to adjust to the clutch bell without glazing. The only difference between two clutches is the clutch spring rate, which provides the optimal range for clutch engagement depending on the application. The three available versions of clutch springs provide adjustability within the following RPM ranges:Silver springs 1.3 mm y0730/05 (standard on Big Scale Cross): 5,000 9,500 RPMGold springs y0730/06 1.4 mm (standard on Big Scale Race): 6,500-11,500 rpm Adjustment:Adjustment of the clutch engagement speed is done by one single screw using a 2.5 mm Allen wrench. Turning the screw in increases the stall speed, backing it out will lower the stall speed. The adjusting screw is thread locked to keep the setting. Should you realize that the screw can be turned too easily please re-apply medium strength thread locking compound.Finding the best clutch engagement speed:The best clutch engagement speed should be found while driving on the track, it depends on engine characteristic, track layout, track surface and driving style.It is recommended to start with the lowest setting (which means the set screw just touching the adjustment cam) and gradually turning the adjusting screw in while doing test runs after every adjustment.If you feel that you have exceeded your best engagement speed (clutch will slip too much), back the screw out for a little bit to avoid excessive wear or glazing of the pads.Attention: You must use adhesive y0743 Clutch-Safe when replacing clutch pads!

TXLA-910 Tourex Big-Speed Automatic for FG/HPI/Losi/Smartech and many more

For off-road applications (buggy or truck) Tourex Automatic clutches with an engagement speed of about 7,000 - 8,500 rpm are recommended! For 1/5 on-road applications you will usually run Tourex Automatic clutches with an engagement speed of about 8,500 or 10,800 rpm. The Tourex Automatic clutches are available in several configurations: Item no.:Clutch body:Friction material: Clutch spring:Engagement speed:TXLS910 Standard 4 x Carbon1,8 mm7.000 rpmTXLA-910-L.Mix Standard 1 x Carbon, 3 x Alloy 2,0 mm8.500 rpmTXLA-910-MIX Standard 1 x Carbon, 3 x Alloy 2,3 mm10.800 rpmTXLA-910-MIX-MC Short 1 x Carbon, 3 x Alloy 2,3 mm10.800 rpmTXLA-910-F1 Short 4 x Carbon 1,8 mm7.000 rpmTXLA-910-F1-MIX Short 1 x Carbon, 3 x Alloy 2,3 mm10.800 rpm Original text of the manufacturer:The Tourex Big-Speed automatic clutch system is especially developed to meet the high demands from our customers. Since engines become faster and stronger these days, the clutch has to handle much more power than before. This clutch is basically the same for all cars, only the center part is different. So when you change your car youll only need a different center part. This new clutch has 4 shoes which engaging action can be adjusted to your personal preference through changing the springs. You are now able to allow 2 shoes to engage earlier by 700 to 2000 rpm. When the engine has enough rpm to press all 4 shoes against the bell, the spring preload is neutralized. The reason for this: the center part, which is attached to the crankshaft and carries the clutch body on three ball bearings, turns 30 degrees once all 4 shoes touch the bell, increasing pressure on the shoes from down below to a higher value than possible through centrifugal force alone. The stronger the engine, the more additional clutch pressure will be generated. The result: better acceleration through significantly reduced slippage. This will protect your clutch shoes from wear and damage! When the throttle is released, the center part disengages and the springs are re-activated within milliseconds. With this new system the wear of the shoes is significantly reduced. This clutch is especially designed for models with high power engines such as the heavy like Losi 5ive-T. You can off course use this new clutch system in all models. And yes, you can personalize the characteristics of the clutch by changing the spring strength and shoe combination!Contents:1 piece

y1419 Sintered steel clutch for Zenoah and many other engines from 23 cm³ to 32 cm³

Sintered steel clutch for Zenoah and many other rc-car engines from 23 cm³ to 32 cm³.Note: The sintered steel clutch needs a break in period of at least half an hour run time after their first installation. Only then the clutch surface reaches the desired grip and provides the necessary friction. After that the clutch will show consistent operation and extremely low wear!With 80 grams the weight of the clutch is about the same as the usual OEM clutches.As with all non-adjustable clutches a periodic monitoring of the clutch spring is recommended. By changing the spring, it is also possible to match your car to the track conditions, i.e.: the harder the spring, the higher the stall speed of the clutch.If not on hand, for installation of the sintered steel clutch a clutch spring, the Zenoah screw set # 7318 and the original Zenoah clutch mount # 7315 are required!
