can anyone give a little z-engineering help..... :(

[nimpy 1]

Recently fitted a z-eng blower to my obd 2.9, no problems, leaked a little oil, but worked fine. Was out last night, and about a mile into the journey the chrger started to make a high pitched whining noise, it stopped again a couple of minutes later, and was replaced by a noise like someyhing hitting the blades, pulled over and took the pipes off, nothing. No marks on the blades either. Perfect. Went to pull off and the noise was still there, drove the 2 miles home, and the noise disapeared. There is now a very faint noise when slowing down, which I am sure wasnt there before. Could this be the bearing? I have heard horror stories of the bearing dying on these, Or am I just being too paranoid?

thanks for any help

im sure ben will be along soon to help u with this as he is running one, is it a stage 1 or 2..a smooth belt or toothed ? This would be handy to no the answer on this as im watein to put mine on

its a stage one zr 1, ribbed belts.

Forgot to say the car stalled whrn I dipped the clutch before I pulled over, but then it started and ran fine after I had inspected it.

ok i know what it is now, air silter has gone, and blower must have sucked something up. although there was no visible damage to the impeller, when I got the othe pipes off, bits of blade were lying in the charger and the compressor blades were marked. 2 of them gone. So anyone know where I can get another imnpeller form ????

mm tough one that , id say z engineering direct, or a turbo place.

look up sln in germany as they do zr rebuilds or z enginnering in switzerland as they will have the components to fix but u r better off sending it to them and fixing and upgrading it to a zr2 with a stage 2 pulley

SLS tuning is where i got my belt from! dont know if they do rebulids

let us know the outcome mate

[nimpy 1]

not had a respose from any of them, vf no longer have any parts. I have found a few companies that make supercharger impellers though, so it may be a case of taking it appart and getting the dims of the impeller, and getting a match, well hopefully

Easy to take apart mate just 3 bolts to take the bracket off and then all the little allen key bolts around the outside to split the two halves, took mine apart to have the casing powder coated, the only thing I would do is mark on it where the two bits line up again when u go to put it back together !!

after 3 1/2 long months I have a new impeller, Hayward superchargers sorted me one out . I have a new problem now though, Has anyone any experience of removing the bearings form the charger? I have removed the bearing unit with the shaft and bearings, but am at a loss as to how to remove the bearings themselves. Is there just the 2? or is there a 3rd one inside?

thanks for any help
