2010年1月15日 · 1 - Cut and plug the oil line at the engine so that the oil side of the VRO pump will not draw air into its system. Trace the wires from the back of the VRO to its rubber plug (electrical plug) and disconnect it. 2 - Trace the two wires from the oil tank to the engine, disconnect those two wires, then remove them and the oil tank.

2010年12月17日 · Re: VRO Pump Leaking Badly! Tom, you can purchase Bombardier part# 0438559 (std. fuel pump) . Utilize the VRO bracket by cutting and placing a small piece of aluminum roof flashing over the surface of the open area in the VRO bracket( where the VRO pump used to be) and mount that smaller pump to that flat surface (use small s/s bolts or …

2020年6月2日 · Hi I-boaters, Happy Summer for the USA folk! I recently decided to replace the diaphragm kit for my 98 150, 60 Looper. Even though the motor runs fine it was more prevention because I don't have genuine hours. Motor looks brand new but you never know internally. After reassembling the...

2011年12月2日 · i just completed a conversion on my 2000 50 hp johnson 2 cycle. i removed the VRO, pulse limiter nipple which connects to the VRO via a hose, unlpugged the VRO wire haress in the lower pan area port side. plugged the pulse limiter tap with a napa brass pipe plug after opening threads slightly with a tapered pipe plug tap of the same thread size.

2009年7月21日 · Ran clear hose on output side of VRO and pressure tested. At 800 RPMs the pressure would gradually drop from 7 to 3.5 PSI within 15 to 18 second cycles. Each time pressure reached about 3.5 PSI, I noticed a very small group of bubbles (very small- probably combined would make one 1/16 in diam bubble) that pass out of the fuel outlet.

2002年1月28日 · Re: Vro pump, how to check The VRO is both a fuel pump and an oil pump - it is operated by an air motor which uses a diaphragm and rectifier valves to convert crankcase pressure and vacuum pulses into motion for the pump's 2 chambers. The most common failure in a VRO is the air motor diaphragm, when it fails, the pump doesn't work - period.

2020年6月17日 · The VRO is part of the fuel pump so when one fails, the other does too. Lots of people will blame their oil pump when it was actually a different problem. These VRO pumps are very reliable but take the blame a lot. If you are changing your fuel pump I'd consider it as it is significantly cheaper without the VRO. If so, go 50:1 and enjoy your day!

2003年12月18日 · Re: How reliable is the VRO system? I have been reading the posts about VRO for some time now. 90% say to disconnect and 10% say leave it alone. I have an 86 Johnson with Vro and after reading all of these posts I disconnected it. Now I read it's ok to leave it hooked up! I guess it boils down to what you feel comfortable with.

2012年6月23日 · Re: VRO Failure- What are the symtoms? Quick death or slow failure. My VRO gave no symptom I can remember. The motor ran wonderfully. Then one day I took my kids tubing, and the motor just shut off after 5 minutes. It would run at idle for a few minutes, we'd open it up, and it would die again. I thought fuel pump, electrical heating, etc.
