ENGINE VIBRATION ELIMINATORS for ENGINES 6.5cc to 90cc

engines-eve 20-45cc

Two substantial polyurethane vibration absorbing top hat shaped bushings sandwich the firewall and encase the retaining bolts to ensure complete high stress engine security. The bolts pass through a stainless steel spacer sleeve which is clamped between the snubber washers when the nut is tightened down. This prevents any fretting between the bolts and engine mount. You will see this mounting system shown on many Ziroli plans. It is the only anti-vibration mount that is endorsed by Neil Tidey for Laser engines. Use additional mounts for larger engines and other applications.

A 6mm ply pad is glued to the 6mm ply firewall at the location of each EVE to increase the length of bushing around the bolt. This pad can be placed on the front or rear face of the firewall depending on the need to move the engine forwards or backwards to align the prop driver face with the front of the cowl.

The M5 bolt is screwed directly into the stand off spacer and secured with a thread lock compound.

.60-.91 cu in - 4 small blue bushings with M4 bolts - £7.50

Originally developed by a requirement to mount an OS91FS, these EVEs are a scaled down application of the assembly detailed above, but do not have the internal spacer sleeve - this allows the necessary degree of bushing compression adjustment to fit any 2 or 4 stroke engine from .60 to .91 cu in, as well as facilitating thrust offset variation by tightening individual bolts

20-45cc - 4 large red bushings with M5 bolts - £11.00

These EVEs are designed for any type of engine in the 20-45cc range. They feature a stainless steel spacer sleeve that enables the engine mount to be solidly clamped between the M5 bolt and nyloc nut to prevent fretting. This is the only system that works with Laser engines - isolating the engine from the airframe, but securing it from torsional movement to prevent carb intake oscillation causes fuel/mixture supply problems. Suitable for radial/back plate or stand off mounted 2/4 stroke glow and 2/4 stroke petrol engines.
