Engine casing bolt M7 x 94mm -VESPA- 80-14mm

The Vespa housings are fixed in the classic way, mostly by tie rods. Unlike stud bolts, tie rods are not screwed into the housing, but are guided through a bore hole that runs through both housing parts to be connected, and in the case of the Vespa motors are screwed on one side. The other side of the housing bolt (tie rod) has a head without a wrench but with an anti-twist device.
This technique minimizes the continuous effect on the thread, the torque distribution in the housing is better, but the main advantage is of course the more cost-effective production of the housing, because no threads have to be set here.

The 98mm engine housing bolt shown here is the longest bolt used in large frame engines such as Sprint, Rally, PX, Cosa and T5 engine housings. It is mounted at the height of the kick starter and runs through the hollow profile of the engine swing arm.
It is pushed through the housing from the clutch side, below the clutch cover. On older vehicles, this bolt is often heavily corroded in the middle, where it is exposed to both air and spray. Then the bolt is often difficult or impossible to remove from the housing.

• Length: 98mm
• Thread: M7
• Material: Steel, burnished/galvanized
• Scope of delivery: without nut, without washer or snap ring

Tip: To disassemble the engine halves, leave this bolt in the housing if it is stuck. The small motor half can still be removed and you avoid the risk of drilling out a bolt deformed by attempts to drive it out.
When fitting a new bolt, grease it well!
