New Mangoletsi “Sliding set up” linkage

Weber DCOE and Dellorto DHLA - Patent Pending No. 0922289.4
Supplied with service kit for long life, Allen keys and instructions

easy fit

Simply bolt the ready assembled linkage to the top of the carburettor. The casting is profiled to the shape of the carburettor lid and carries the linkage assembly alongside the carburettor, preserving the classic style.  The ultra-low profile makes it suitable for all applications - Height over highest part of carburettor -  Weber 10mm:  Dellorto 5mm

easy set-up

All aftermarket throttle linkages have to fit a wide range of different applications and makes, all with different throttle cable travel and spring tension requirements.  Unless the linkage system has a very wide range of adjustment for the throttle cable travel, for some applications it can be difficult to fully open or close the throttle. The Mangoletsi linkage has 22 – 48mm of adjustment.  Adjusting the linkage for the correct cable travel will then alter the tension of the pull-off springs.  Therefore it will be necessary to adjust the spring tension to positively return the engine to idle or give a good “feel” to the throttle pedal.  Many aftermarket linkages have little or no adjustment.     

With the new Mangoletsi sliding set-up linkage it is absolute simplicity to set both the cable travel and the spring tension, thus ensuring sufficient tension to guarantee complete closure of the throttle plates.

1 SET the throttle pedal travel, slacken bolt on cable clamp carrier and SLIDE the whole cable clamp assembly along the slots until throttle fully open and throttle fully closed positions are achieved.  Tighten bolt

PHOTO

2 SET the rate of throttle opening – To obtain the optimum “feel” the rate of opening the throttle can be fine-tuned by adjusting the centres of the ball joints by rotating the hex joining bar to positions specified in instructions.

3 SET the spring tension – slacken nuts, SLIDE spring/cable carrier assembly until a good balance between idle shut-off and pedal feel is obtained. Tighten nuts.

4 SET throttle stop screw

Unique Geometry

The cables, return springs, ball joint hex joining bar and throttle lever all operate in the same plane.  The smallest movement on the cable is translated with no lost motion to the throttle lever.  The return spring reacts directly against the joining bar to the throttle lever – result, a very responsive and progressive throttle feel. 

SO SIMPLE – SO ADVANCED

Designed and constructed for competition use

The objective was to design a linkage where every component is engineered to the highest possible specification for reliability and functionality.

  • For smooth operation and long life, all rotating parts run on five phosphor bronze bushes
  • Left and right hand steel ball joints are fitted with anti-dust seals and are joined by a 8mm hex bar, threaded at either end, with central spanner or finger adjustment
  • Twin return springs securely located in anchor bars with circular grooves enables the spring loop to rotate smoothly as the throttles are opened/closed
  • Cable adjusters located in a rotatable barrel which enables the cables always to follow the direct line of tension, without the chafing to the inner cable that occurs (except when the cable runs around a quadrant) when a lever is operated from a fixed cable adjustor.
  • Cable travel range: minimum 22mm – maximum 48mm
  • Anti-vibration precautions - Nylok nuts and bolts are used on every component that could work loose.  The stud screwed into the casting for the main operating lever is roll pinned.  The bronze bush pressed into the main operating lever is roll pinned to the lever
  • For long life all steel components are plated passivated silver or gold finish and washers, roll pins and split pins are stainless steel.
  • Adjustable pedal stop – protects linkage and carburettors from overloading.

Cables
2 off one metre long cables with nylon liners.  The bulkhead fixing is with adjustable heavy duty threaded bar on the outer cable with locknuts. Supplied with tie-wraps to support cables.

Pedal Block
Easy-fit split pedal block is clamped either side of the pedal shaft with 2 bolts. 

Advantages:-

  • The block can accommodate varying thickness of shaft and clamps very firmly with the 2 bolts and lock nuts, precluding the possibility of the block rotating, which can occur with other methods.
  • Throttle pedal blocks with single holes can be difficult to feed over shafts that are not straight, or that have the manufacturer’s original attachments welded to them.
  • The inner cable nipples are trapped between the two blocks and cannot jump out of their location
