81 Cat 955L w/right undercarriage leak

Lil Red ยท 2024-07-08 10:15

Can someone give me an idea on how critical this leak could be? Unit hasn't been run in 6 months and doesn't appear to be leaking profusely but can someone give me insight on how much effort it would take to repair it? Thanks in advance for any responses provided.

    looks like you just need to reseal that bottom cover also check for cracks or spots wore thru

    Fixed several other higher priority issues and now ready to take care of the smaller leaks. Can someone point me in right direction of part number for these bottom cover gaskets/seals? This is 1971 955K serial # 85J04171

    Don't you mean 7M-7260.? Loctite Hi-Tack MR5009 is the replacement since Cat got out of the sealants and chemicals market a few years back.
