Ms 171 oil leak

[div_h]

Anyone else's 171 leak bar oil? I gave it I wipe down last week and picked it up today and its in a puddle of oil! I've checked the pipe from the pump to the tank and it seems good, but I've put it back in with a smear of RTV like stuff around it..I meant to fill it up tonight before I left work the check in in the A.M.

Not sure about 171, but my 181 has done dropped oil from being about a month old not much though. Probably (as said above ) from left running on hard surface. Most likely the the plastic bonding

We have seen a few with oil leaks. First thing is pressure test the oil tank if you can. See if there is a leak along tank joint, if so its a new tank or we have in the past grooved out the tank and rebonded it. If its not the joint, then inspect the oil pipe where the grommit goes into the body. If need be change the oil pipe. Next check the oil tank cap is sealing properly. If this is all good then use saw for 10 mins and place on a clean sheet of cardboard. Leave for 12 hours and check for a puddle of oil. Move to a clean piece of card and leave again, if there is the same amount of oil then there is a crack or split somewhere. If it is far less then it is oil passing the oil pump and running out after use. There appears to be 2 designs of oil pump, the later of which has a flared outlet. We have removed the old oil pump without the flare and replaced with new type and oil leaks have reduced or stopped. Both types of oil pump appear to have the same part number
