oil pressure problem

Postby staggert62 » Sat Mar 12, 2011 1:35 pm



Hey all,

Hope someone can help me,I have a 1982 honda goldwing GL 1100I that wife bought me for Christmas it only has 21000 miles on it.
I changed the oil and done few other minor repairs to it and it was doing good . Then all the sudden the oil light came on; I changed the oil pressure switch but the problem remains. Can anyone give me anything else to check or do other then putting it in the shop?


Thanks

You might hook up a pressure gauge where the pressure switch is installed to be sure there is no oil pressure. If no oil pressure than you are in for some internal work. Good Luck

If the problem remains with a new oil pressure switch, then you've got one of two problems:

1. Oil pressure switch wire is shorted somewhere between the instrument cluster and the switch
2. Low oil pressure

The first one is easy to diagnose - disconnect the wire from the oil pressure switch and see if the light stays on. If it does, then #1 is your problem. If not, then you most likely actually do have an oil pressure problem. Check your oil filter for blockage, it could also be a clogged oil screen in the engine, or one of the two oil pumps could actually be failing.

I had the same problem with my '83 Interstate.
Took the sensor and oil screen off and surprise surprise! The screen wasn't dirty, it was totally coated over with crud. I couldn't even see any metal screen showing on either side it was coated so badly. How oil ever managed to squeeze by is beyound me. Fortunately it cleaned up good as new.
Took the bike out for a couple loops around the area (same loop I took a few days ago when I first had the light come on) and the bike ran fine. A hundred miles later and no problem with the oil light acting up.
The cover is a pain to get off, but I used a shorter bolt (M6x1.0x16mm) when reinstalling and getting it back on was a lot easier.
If the bike only has 21k on it, it probably sat for a few years and the oil may have gunked up on you.

This is a good example of what you might find! If so, while you have the filter out, take off the timing plug and pour some kerosene down to flush the rest of the crud out. Trust me, you'll be amazed at the muck that arrives in your container. :shock:

Yeah! Pity the poor sods with a 1200 ! You need to split the cases to get the screen out of it. :o Great piece of design, Honda :roll:

Same idea. I did something similar last fall - I changed the oil, added a can of Seafoam to the fresh oil in the crankcase, went out and rode for half an hour, then came back and drained it. What came out was the most disgusting, filthy, grey muck - I couldn't believe what came out. I think I will plan to do that every year from now on.

Seafoam is naphtha, isopropanol and "pale oil". The flash point is 55 degrees F. Lubricity is not listed in the chemical properties.

I'm not advocating riding the bike with kerosene in it, simply that you could use it to flush out the nasties whilst you have the crankcase filter cover off to clean the screen.
Kerosene, or what we call paraffin over here, is what jet engines run on. It's my belief that it's a further distillation of diesel fuel oil, though not totally sure on that. It's certainly lighter than diesel oil.
Never used MMO as it's not available over here, but I know you guys in the States seem to swear by it. As far as I can make out, MMO and ATF seem to have about equal qualities as to the cleaning out of the engine and as long as you run it lightly, don't seem to have any detrimental effect on parts.
I have to say that I would be very wary of running any of our engines under load (ie riding it) with the oil thinned out by anything given the cost, lack of availability of shells and the amount of work involved in replacing the bearings if something goes wrong. Running it up on the stand is a different matter.

Is it possible to remove the (1983 Std.) oil strainer screen with the engine still in the bike??? If so, is there a tutorial on the subject? Any help from someone that has been down this road before will be greatly appreciated. :?

Taking the Oil strainer is not difficult, its at the bottom of the engine on the right hand side near the neutral indicator switch. The strainer is good at catching debris such as bits off the clutch plates.
Drain the OIl, put the bike on the side stand, remove the 4 bolts that hold the filter in. Some bike have allen bolts some have cross headed screws. If screws use a right angled screwdriver to remove them. You may have to remove the main left to right eninge mounting bolt and spring the frame as well.
Springing the frame is also necessary for changing the neutral indicator switch and is advised in the maintenance manual. Dont forget to put new oil and filter on whilst at it.

Here's a pic showing the location of the crankcase filter.



I've been thinking about this. Honda intends the filter to sit facing down in the crankcase. The screen is a bare 3/8" / 9mm above the c/c floor like that, and obviously from the other picture of the screen I posted, all the crud gets sucked up and sticks to it.
I checked this and the filter can be fitted with the screen UP instead, meaning that the screen is now 7/8" / 22mm high.
Now, granted if anything landed on it, it would stay there. But the muck is staying there anyway, even in the right position. It would also require you to keep the oil level well up towards the top mark, so those of you that check the level once a year probably shouldn't do this. :D
The more I think about this the more it seem to be sensible. The oil at that height is also being agitated by the gear train to some extent so less chance of nasty bits being static.

Might this increase air entrainment?

Totally off the subject, but WOW!!! What a beautiful engine Old Fogey!! Wish mine looked that shiney!!
    You only need two tools in life - wd-40 and duct tape. If it doesn't move and should, use the wd-40. If it shouldn't move and does, use the duct tape!
