How do we know it is time to change the Pegasus Piston?
Typically the Pegasus Steel Piston will begin to allow small amounts of aluminum to bypass the diameter on a consistent basis. Sometimes small amounts of aluminum may bypass from time to time but is not indicative of piston failure. If bypass is repetitive then the piston should be changed.
Can anyone change the barrel of the MX-Sleeve?
NO….Channging the barrel and replacing with new should only be done by Pegasus Industries. Certain procedures need to be followed in order to reuse the outer shells.
How can we reduce lead time for Re-Insert (full barrel replacement)?
If we have a purchase order in advance we can stock a barrel on our shelf which will reduce the lead time by 2-4 weeks.
How many times can a shot sleeve be Re-Inserted w/ a new barrel?
Typically the maximum number of times we can Re-Insert a sleeve is 4. We are restricted by the distance from the ID of the sleeve to the ID of the cooling channels. As we remove the shells each time they must be honed to a smooth finish. This removes stock between the ID of the shell and its internal cooling circuit. Eventually the internal weld fillets will reach its minimum size and the sleeve must be retired.
