Title: Check valve oil leak
Post by: fleetmechanic on March 04, 2021, 12:54:34 PM
Got a 2017 FLHTP that leaks oil where the hose from the check valve is clamped.  Was this a common problem on the early M8s and will I be able to access the clamp without removing a lot of other stuff?

Update:   I found the recall #0170 on this and will proceed to replace the clamp. Old style was an Oetiker type that wasn't crimped right.  New one is a spring clamp.  Footboard and brake pedal need to come off to do it.

What kind of "check valve" is part of the oil cooler lines?

The fitting that the hose is clamped onto is shown as a check valve for air cooled engines.  It
is in the parts book.

Well, this one already had the spring clamp of the type used under recall.  I installed another of the spring style clamps but if it leaks I'll change it to the oetiker style used on the '18-later models. The footboard and the brake pedal had to come off but since I couldn't access
the cotter pin on the pedal I removed the two bolts that hold the master cylinder in place and slid the pedal off the stud with the cotter pin still intact.
