I can't see me being happy with any of these mounts so far. The centre rubber is only 20mm when I need 30mm to support the frame. I could simply make up a bush to take up the slack but then I have a problem with the OD. It's only 33mm and with a hole in the frame at 30mm it's barely hanging on. That's unless I've read it wrong but that's never happened before 😇

Still be worth checking the Chinese price and availability. Chances are it's the exact copy.  Nev

Good idea, where's that Rapture guy?

What a joke, talk about rort of the century! Just eight cup-shaped rubber pads and eight cupped, pressed washers. They're worth about $200 in total.

See a rubber mount manufacturer, they will more than likely be able to knock them up for you.

There's nothing special about the mountings, they're as simple as they come. Their correct technical name is centre fixing isolators, have a chat to Mackay Industrial (Derwent Industries).

The main thing that needs to be established is the Duro (Durometer measure) grade of the rubber. The Duro governs the rubber hardness/softness and it's important the correct Duro is used for the application. Too soft and the rubber will chew out, too hard and too much vibration is transferred to the frame/fuselage/chassis.

These look a hell of a lot like the ones on the Bushcat

The mounting hole in my engine frame is 30.5mm. That means that "E" will have 10mm clearance in the hole. It's never going to hold the engine in the right place. Overall dimension "A" is 33.3mm to cover a 30.5mm hole in the frame. Hit the throttle for a go-around and the engine will leave without the aircraft 🤪

Many manufacturers will use a standard product that is available and buy up stocks, give them their own part number and price them to whatever they like. The Jabiru engine mounts are from some other manufacturer but in Jabirus case they are not exhorbitantly priced though more expensive than buying them from the actual manufacturer.

I found this in Czechoslovakia.

It's a bit more attractive than a $1000+ here. I've just sent a message to a Czech mate to get his suggestion on how to buy.

Sean, I looked at these but the OD has gone the other way. They are 47mm and the frame only has a 42mm recess to fit them in.

The dreadful European freight/postage costs will kill the deal. The only gain is, you can acquire them VAT-free as an overseas purchaser. But the transport cost will blow you away.

I don't think I'm going to do any better than that and I get the genuine part.

I "clicked" on the address - Interesting, but no mention of engine mounts. How did you know they could supply?

 

The discerning buyer will compare supplied cost, not just advertised/ in shop cost. If you got the parts what, when for the price, you found acceptable, good-on- yah!

 

I have seen both overseas/ Au supplied cost, blow out to make that component/material uncompetitive. I am convinced that some suppliers "pad" the low advertised price with outrageous delivery charges (a rort ?)

“PAC” Service Instruction Documents provide detailed information on non-certified ROTAX® Aircraft Engine Parts and Accessories. Referenced parts and accessories are provided without EASA certification or ASTM compliance. Certification / Compliance of referenced Parts and Accessories must be completed by the aircraft OEM.

 

Looks like it's called a PAC mount so that might be a clue when trying to find its origin?
