[NSRCA-discussion] Hacker Gear Box Grease

[Earl Haury]

Jeff

Most of the suitable greases are only sold in large quantities for industrial customers. Shell Stamina RL2 has been the grease of choice for Hacker gearboxes in the US for years, various folks have purchased 12 tube cartons and sold their excess – maybe someone will offer some for sale. The Stamina is discontinued and replaced by Shell Gadus S3 T100 2 (S2 V100 2 is also OK). Amazon lists the latter for $7/12 oz., but shipping from the UK is $27. Sometimes these show up on eBay also.

There are other suitable brands, the trick is finding the right specs, most grease companies provide a spec sheet of their products. For the Hacker gearboxes NLGI Grade 2 is the best thickness, look for a lithium based PAO synthetic designed for high speed / low load applications with a temp range of 100C+ if you choose to go this route.

Does anyone know exactly what grease Hacker is selling for their gear boxes, and a source for larger quantities? ? I understand that many use the Rheolube, but I'm also told that's not exactly the same stuff.  Looking for a more cost effective source than $10 / 2ml.
