Can Lucas hydraulic oil booster & stop leak be used in an old M371 with out damaging the clutch disks? The unit has excess of 25000 hours and was sitting for a few years before I acquired it. After getting it functioning again one of the wheel seals has started leaking. At this point I don't want to invest a lot of money into repairs before I found how sound the machine is. I was planning on changing the chain case oil with Rotella 15W40 and adding the Lucas. Is this a good course of action or will I cause more damage than good? Thanks for any info.
