Custom/Hybrid Superfreak motor mount insert repair.

[Freakrider]

After a million backflips flops in past two years I finally discovered what was causing a rattle at idle. I pulled up a motor mount insert bar.My friend Roland fixed it really strong. Epoxied insert bar in first after drilling some holes in bar and holding box for more grab. Then 12K carbon over it. Whatcha think ?

I did a couple of those this past summer too... Fun times- not! Looks good though.

Yeah lots of prep work....what type of hull did you work on ?

Is that the right rear in matte's old freak?

Glass super freak. Two, if not three, of the mounts came a apart like that....

Exactly, did you ride it and loosen the insert up before he sold it ? jk...had a rattle for for a long time couldn't figure out from where, the insert bar must have been moving under the carbon. Been doing flips with three couch mounts for a long time, apparently.

Nope Matt did that on some monster V wake hits (blew apart a bunch of CF mounts when it broke out the first time). I did the repair on it. I remember it being a pain in the ass because I didn't want to build it up too high with multiple layers and make alignment difficult. If you got two years of pancakes out of it I'd say it did it's job (surprised it lasted that long). That little anchor bar doesn't do much for distributing pull when you land upside down. I layered that with glass before the carbon to try and prohibit the galvanic corrosion between carbon and aluminum.

Wow, is that little bar how all of the superfreak engine mounts are done?

It didn't last 2 yrs, it's been rattling for probably a year now at least and we didn't know what the noise was because how it's hidden under the mount. The recipient box for anchor bar is fastened in with carbon around it and should not react to the aluminum.

It was corroded the first time from the carbon being laid directly over the aluminum. The little aluminum block was just sandwiched between two pieces of coremat that were the same height with a layer of carbon over the top. We hit the aluminum with a flap wheel then immediately brushed resin on to prevent oxidizing. Then cabosiled it back in place and layered over it.

I really don't know but the other 3 look solid still.

That 12K carbon fiber is super strong/thick stuff. Might have to use sanding belt on that couch mount now to compensate height.

Also a tip/ trick is to drill holes in anchor bar and box for better epoxy adhesion.

@whitca how many anchor bars did you repair ?

Just that one if I recall, might have done both on that side.

I lied, it was the front right....here's the thread from the carnage.

The wrong landing with these that Matt_E was doing will certainly test those inserts.

So you're fixing the rear right correct? Front right closest to the battery box (or pfp waterbox) is still intact?

Yes fixed right rear....far as I know front right is good maybe I better check the front right further since it's no longer oem spec
