>>the special seals that are located in the cartridge behind the bearings, where the rotor shafts would enter the case<<
These appear to be a special part that prevent the flow of supercharger fluid from the cartridge into the case, as well as the flow of compressed charge air (boost) from the case into the cartridge.<<
If someone knows what type of seals these are and can inform me that would be nice?(saw one thread that said they would be neoprene? seals?) I just took teh first rotor/gear apart and found out that itīs pretty press fit..(have to warm the gear when putting it together too)What is the best way to get the rotor clearances right when putting it together and how to do it..since the splines in the rotor shaft are just tiny ones that have been used to get it tight at first plase..not to align the shaft? I can put it together but itīs better if someone could give me some advise..since I live far away from any rebuilding service facility. I will take some pictures tomorrow and post them here so everyone can see them. The bearings are cased too as some of you might know but that should not be the problem...(Iīll take them apart tomorrow)If right size seals can not be found I think itīs fairly easy to lathe the rotor shaft(21.80mm) and bearing seat to proper dimensions for differend seal with better availibility...
I hope someone with knowledge of this would inform me A.S.A.P. so we could save one SC again . Mine was leaking oil to intake
and the nose seal was gone too..but rotors are fine as everything else too..
+any other clearance/blueprint info of the supercharger is welcome..what is the minimium clearance between case and rotors that it would still work as it should with normal RPM range.
I have searched all the threads and found no other info of the rotor/gear thingie or proper clearances So if you know something please share your aknowledge. Iīm willing to share mine after this rebuild..we get out of this mystic rebuild ones and for all. Sorry if it takes someone out of business tho..but how many has press of their own...really. So the loss of customers is probably not an issue here. It will reguire special tools always.
