Rock drill grease - special?

[Dimonsof]

Hi all!

We have CAT MD5150C Drill in mine (West Africa). We only got it delivered 2 days ago, and now CAT representative telling us that for the top hammer (HPR6030 Hydraulic Rock Drill) we have to have "Special Rock Drill Grease YPG55 for Drill Lubrication System" (from SIS) and here are specs:
DROP POINT 288 C (550 F) ASTM D556
PENETRATION 245-265 mm ASTM D217
NLGI GRADE 2.5 or equivalent
TIMKIN LOAD 22.7 kg (50 lbs) ASTM D2509
SPECIFIC GRAVITY (H20 = 1) : 0.8
FLASH POINT 204 C (400 F) Direct Flame
VAPOR PRESSURE <0.01
MEETS MIL. SPEC G-10924C or equivalent

Of coarse, as usual in this kind of location - local dealer doesn't have any in stock and will take quite a time till we get it air freighted. I tried to with local Total dealer - they can't cross it to any of their products. In Namibia (on previous project) we were just using Mobil XHP 322 MINE Grease, but the drill we had there was CAT MD5125 and there is nothing special in the manual for MD5125 regarding that grease.

Has anybody faced such a problem before? What do you normally use for Rock drill grease (any other lube brand maybe?)

Thanks in advance,
Dima

Most mines will use the EP grease they run on the rolling stock. Im surprised CAT didnt have anything on hand.

Hi blitz.
We are in Mali and local CAT dealer is most of the time just dealer by name.
Can you give me any particular grease descriptions that can match?
Thanks,
Dima

Hi!

No, we didn't find any replacement, but we were lucky to locate it in US and purchased directly from Winzer. The price was pretty reasonable (5 times cheaper than from local CAT dealer).

Hi. We bought it in 20L buckets. And this was exactly the same as CAT YPG55. We purchased at the beginning couple buckets from CAT (at very high price) - and they were same winzer buckets with little CAT sticker on the top.
