What's that loud clunk?

I got mine rebuilt about 6 weeks ago. No more leakage and it's quieter too.

Make sure to tell them it's a Comptech Novi 1000 - apparently there's a difference in bearing sizes.

 

thankyou for the help u guys are great!!!

 

As above there is absoloutly a difference between different models, earlier Comptechs use smaller seals/bearing.

 

How do you know what you have?

 

Should be some indication on the tag on the blower, serial number I do believe. Its true there is at least two different NV1000's. My buddy ordered a rebuild kit for his, and turned out he had an older blower so the bearings didn't fit. Mine is the latest series.
