Hi all,
I received a good second hand ABS unit today and thought I would share my findings when I pulled the old one out after a year of riding or 20,000ks. Out of that I would say I have done about 1000ks on dusty gravel roads.
Firstly the unit was covered in dirt and dust. The electrical plug was the usual nightmare to disconnect and the plastic bucket as I call it was full of dirt again.
I was slightly reluctant to drop my new unit into this environment having seen that dirt and moisture ingress through its internals had wrecked my previous unit.
Then I took the electronic side off the ABS unit and found dirt back inside after I assembled it spotlessly clean.
This unit hasn’t even been operating for the last 8 months so I think we have a problem...
I started to look at ways of sealing the housing the unit sits in but this isn’t feasible with the ridged lines that go forward.
I have decided to make a clean air manifold for the vents at the bottom of the new unit using clear tube and plumbing it forward into a cleaner environment.
Here is a picture looking down on the internals of the 4 vents. I shon a torch to show the 4 vents.
Clearly it doesn’t need 4 drains in the event of an internal leak so I sealed up the highest 2 leaving the middle and lowest 2 open.
I sealed the perimeter of the plastic ecu to the valve body as there is no seal between the two. I am using Dow Corning 730 silicon based sealant that is resistant to fuels and oils.
I sliced about half off some clear 1/4 hose the length of the remaining 2 vents and super glued this over the 2 vents then edge sealed this and plugged the open end with DC730.
I know it’s ugly but at $1000NZD I just want it to last and plus you can’t see it when it’s installed.
I am going to drill a hole in the right hand side of the mounting box for the drain/vent hose to come out of and then run this forward to some clean air. I’ll update this when the sealant dries.
