ADVISORY: PoweriSer 2007 lower bracket bearing replacements

[XarnuSonci]

There has been a problem with the lower bracket of the 2007 model poweriser lower bracket bushings causing the rod-D part to deform and reduce the preformance and lifespan of these bocks.

If you purchased these stilts in the USA through xphub.com or one of its retailers you should be entitled to a replacement set of bearings.

If your stilts look like this you do not have them and should contact your retailer:


if your stilts look like this you already have these bearings, be happy:


All new PR 2007's sold after this post should have these bearings factory installed.

If you purchased your stilts from another source you may still be eligible for these parts but that is up to your retailer, contact them directly.

Mine have the bearings, but they wiggle just a bit at that joint.  There is some play between the top and bottom parts.  Is that supposed to happen?

[XarnuSonci]

not really, you can try contacting your retailer, but if its minimal they'll prolly not do anything about it, as much as these need to be precision made, no stilts are 100% perfect, so there's gonna be little wobbles and things, check the tightness of the bolts, that's really all you can do.

What kind of performance problems? i hate to say it, but i got a pair of the 2007 powerisers, i used them a lot, them it rained almost everyday for like two months, then i got really bust with work, and now i rarely get on them, so i wouldnt notice. also, should i just email xphub?

[XarnuSonci]

yup
tell them you saw this and need the bearing replacements and they should hook you up

I got some for christmas but they came from powerizerz.com will they offer the new bearing?? And my uncle orderd the 90120 size spring and i weigh 150. is that too much of a difference or will i eventually be able to use them to the full potential?

[ElectricStapler]

Because of the name, i'd assume they are fly jumpers, so no, and these are for 07 poweriSers only (however, if you ask and you have classic poweriSers and have a legit reason, they will give them to you.)

90120 is a lot, 7090's would have been better but they will break in and you'll be ok in time.

read the first post, if they look like the top picture and are from xphub or one of its dealers, then yes you can get new ones, if they look like the bottom picture, or are not from xphub or one of its dealers, then you're on your own.

[zerocool]

can you get/ will they fit the fly jumper?

[XarnuSonci]

if you email xphub they'll prolly sell you a set, i cannot gaurantee it but they will probably fit flyjumpers

[zerocool]

I contacted xphub and will keep you posted on their responce about the bearings
and the price for non warranty claims

[zerocool]

Xphub sent me a set of bearings and they went on without any problems
on a pair of powriZer pro/ flyjumper pro MB100

I shattered the black plastic bearing when my spring snapped (3 parts)
the spring is tighter and no longer does it have any play when i jump

UPDATE: 

Nick and I fashioned our own bearing sleeves with 1/2inch copper tubing.  I'll take pictures in the near future, but it altogether stopped the spring play, and the metal from bending inwards.

has anybody installed the washer set that xpub is sending out?  am told this is a temporary fix while waiting for factory to mold the new part to correct the d-rod bending problem.  i called yesterday and reminded him i was waiting and got the tracking today.  i was considering consulting with a machinist to work out this issue but think maybe i should give this a try first.  it would be great to get feedback from someone who has already tried them out.

[XarnuSonci]

is this a new washer set?
