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
