Lower engine mount...once more.
Just finished this:
If I'll have time tomorrow it will go there: I have an entire theory about that shape, let's see if practice confirms it. The material is a tough polyurethane, I use it to make these and it works great in off road:

(RTV PU is not tough enough for this kind of job.) I will think about the possibilities. Thanks.

wow that's impressive. Maybe people can donate their broken ones to you, might as well as they would normally go in the bin.

You have done away with the two stress points and replaced them with multiple points. If it works well, you could be in business rebuilding old ones. Best of luck. Mick |

Would be very interested in poly-bushing my existing mount, but the problem is i'd need to do a straight swap. Have you considered (like everyone mentioned) an exchange service?
What sort of cost for the bush? |

Great work Fidel
I'm sure you'll have a large market for those! But there is also a large market for the standard rubber bush but maybe modifying it slightly with smaller stress holes to give it longer life whilst maintaining engine noise insulation. The problem for the DIYer though is removing the old bush. Believe me you will run into problems with an exchange service..................... People don't return the old ones!! I tried it with Cooling Fan cowlings............... Even with a hefty surcharge people still didn't return the old ones......... So be warned you will always end up short of exchange units. Regards Jules

The fitting and the usage of this would be interesting.... Due to the tough polyurethane material (as opposed to the rubber), would engine vibration be increased into the passenger compartment?
Playing a Devil's advocate here....

Great idea though, building in multiple stress points over the weedy Rover effort of two. |

Redesigned engine lower mount
Quote:
In the matter of fact it was designed following three principles: 1. Softer than the original (the vibration dampener as it is, not the PU material which is harder) to minimise vibrations on idle. 2. Shorter travel to improve the behaviour on hard acceleration. 3. A shape that makes it unbreakable. This material can be stretched to almost 500% its original length without breaking; and this can never happen, there is no room for it, even if pressed to the limit on one side.
