Clearances

Guys I have a D1 that I would like to rebuild. I have all new bearings and seals. I was wondering if any of yall might know the clearances on the blower. Any help is appreciated.

Thanks
Daniel

Clearances?... what info exactly are you looking for?

I really need to know the clearances from the impeller to the housing so I can make sure it is shimmed right with the new parts.

Well, not to sound ignorant... but I haven't ever taken a head-unit appart before. I had no idea that the impeller was shimmed... I would have figured since everything is made in house with them for the most part that everything would be cut and dry. Why can't you use the same parts as before in regards to shimming?
