If your Mfgr. says:

That motor's 7 years old.
Part is no longer available.
We lose $$ on service!
EPA made me do it!
Parts at central warehouse, you'll get them next month.
We don't make parts for those.
We only do warranty work.

New and rebuilt units carry a 1 (one) year warranty. This is a supplier warranty. Most units have core value (INCLUDED IN PRICE). Return shipping for cores is prepaid, if you have a repairable unit. MasterTech will remit the core credit
after evaluation by the rebuilder.

Core credit may vary depending on condition of core.

Rebuilt and new gearcases are subject to availability.
