This is what’s wrong with mine. It’s giving the symptoms of slobbering but it’s actually coolant. What is your prefix

Im in the UK , I have a feeling this is a D2 5U , you can get the tool aftermarket in the USA reasonable ish (5F8353) you can find the dimensions in the adverts for them to check for sure but it fits a lot of CAT machines.

Im not 100% sure but something is telling me now the older 5J had a different tool to get them out so best check 1st
