1985 ez go oil pump??

socal760

so i did my homework a little and read previous post on removing the oil pump, seem pretty easy..i intended of doing so myself but i loose things pretty easy or misplace them so i decided to not remove the pump but cut the lines and plug them up i highlighted what i cut in orange.. can i get away with that or do i absolutely have to remove everything. my second question is do i have to disconnect the cable from the pump to the carb? i drew a circle around that cable im talking about

You can do whatever you feel comfortable with, however you must seal the oil line to the elbow behind the carburetor to stop it sucking air. What I did was to cut the plastic pipe about 1 inch from the banjo bolt and drive a suitably sized screw (covered in mastic) into the pipe.

The oil pump is held on by two small bolts and I thought that it looked neater to remove all that stuff as well as the oil reservoir. I wouldn't worry about losing stuff I know exactly were mine is, in the local landfill and good ridence.

is there any way you can pin point me to exactly what your talking about from the picture i posted up that would be really help full maybe illustrate an arrow..i apologize ahead of time im a noobie but just trying to learn..there is plenty of good info and golf cart gurus here. thank you

if you're referring to the line you highlighted in orange, that's the oil line ... disconnect it at both ends, and the end on the intake will need to be plugged (you can always leave that end connected and just cut the line an inch or two out, then plug it with a bolt as Dave suggested). Everthing else involved can go.

i was referring to that metal wire its the 3rd one down if you look at the picture the way it is now..right next to what appears to be the throttle cable and governor i believe..ill have to put a orange circle on it since you cant really seem to see the light pencil mark circle thats on there now..you guys really are helpful

BrewCityMusic

Aaaaah - from the top of the carb to the actual oiler itself, right? as in, at the top of the carb, you have throttle, choke, and that one, right? dump it. bye bye :)

socal760

alright fellas i edited the pic and drew an orange circle with an arrow..BCM your saying to go ahead and get rid of it? what is that cable for whats its purpose if you dont mind me asking. now that i have you guys looking at the picture can you tell me where the gov is at?

Dave Box

Hi Socal, There is nothing wrong with not knowing and there is a lot right with asking questions. What would be very wrong is assuming you know and making a bad mistake, so keep asking. Most folks here are only here because they get a buzz out of helping fellow cart enthusiasts out.

So looking at your picture find the left side of the top orange line. This is the input of the oil line to the engine. I recommend that you cut here, about a inch from the engine and seal it up. You can also remove the banjo bolt from the elbow and replace it with a regular bolt but this means you finding one of the correct length and the correct thread, not difficult but I took the easy way.

Now the reason you have an oil pump goes back to the dark ages when the Environmental Protection Agency (EPA) was just an embryo. One of the reasons (actually the only reason) that the 2 cycle engine is no more is that it is a bit of a polluter. If you look at a model of one running
http://en.wikipedia.org/wiki/File:Ar...e_Zweitakt.gif
you can see that the inlet port and the outlet port are open at the same time which dumps a small amount of unburnt hydrocarbon into the atmosphere. In addition drivers who insist on running an overly rich oil mixture just dump that to the outside world. Now in the late 70's engineers at Honda realized that the slower the engine ran, the less oil it needed, conversely the faster it ran ....... you guessed it. This is the reason you have an oil pump and the reason it is linked to the throttle, the more open the throttle the more open the oil pump. It all sounds great but there is one problem. If the pump gives up or if the cable breaks the engine is suddenly starved of oil and eventually will seize. This is why many guys, myself included, feel a lot more comfortable by premixing the oil in the fuel tank. The disadvantage is that you will be running the cart at the ratio of oil to gas as if it was running flat out even when it is idling and thus adding to the world's pollution burden. On the positive side most carts are driven balls to the wall and still produce a tiny fraction of the mess a Hummer emits. In short if you decide to premix just disconnect the cable to the oil pump, and the pump itself and toss them both.

With regards to the governor, there is a cable that runs from the carburetor to the driven clutch. As the cart goes faster the driven clutch expands and at a certain point will pull on the cable and automatically close your throttle. This is a nice safety feature that was probably developed to prevent drunken golfers from suing the cart manufacturer. My take is that only my wife and I drive our cart and we long ago realized that the throttle works both ways. I have had this discussion here before and some guys have kids/relatives/drunken buddies driving their's and they like the idea of limiting the speed, and possibly stress on the engine, the decision is yours.

That said if you do decide to keep it you have a small amount of work to do. Behind the carburetor throttle arm on the throttle cable you are missing a small spring which goes between the arm and the throttle cable stop. You will also notice that someone has put an inch or so of slack on the governor cable presumably to compensate for the missing spring. (The governor cable would normally pull against the spring to close the throttle despite the pressure of your foot on the throttle). What ever you decide about the throttle you must fit that spring as it ensures that the throttle is tightly closed when you back off the throttle. Without this when you go down hill your cart will backfire and as a 2 stroke has no valves it will make a huge bang. This will cause old ladies to soil themselves and nursing babies to clamp down on their mother's nipples. I am sure you don't want that to happen.

I think that Brew City has a nice photo of this spring and if so I am sure he will post it once he logs on.

I hope this helps.

Kids, Relatives, and Drunken Buddies ... I resemble that remark !!!

Dave - this has been an entirely TOO stressful morning preparing for the evenings debauchery, Thanks as always for adding a touch of Brevity to the day!

NOW ... As to the spring, yes I agree you need it, the main reason being that I lost mine (again) last week when I pulled the carb to give it it's bi-monthly cleanout, and I'm back to popping on the down revs (so the pic will have to wait until I get ahold of another one, probably tuesday unless I find another clicky-pen around here to disassemble)

Wish I could be of more help today - I'm off to tend the smoker and I'll see if I can find a spring, put it on and snap a quick pic

BrewCityMusic

OK, found a clicky-pen in the "Other Half's" purse, heh heh ... Back in business - here's a pic of where it goes:

with your foot off the gas, slide the spring onto the cable and then push the cable clamp down against it until it's tight, then while holding it under pressure, go ahead and tighten the clamp down.

(And before you comment, Dave - I purposely pulled the governor cable to take the pic so it wouldn't be confusing !!!! )
