Lots of oil leaking after stator replacement

[kb_air]

I have a 1978 gs750, i just ordered a new stator and i replaced it. after starting the bike back up and riding it around i noticed a heavy leak. so i went to check the gasket and all of my oil fell out.

ok, so ive done some research and i know how to get a good seal using rtv etc. but is it normal to have ALL your oil spill out? i was under the impression there was just a few teaspoons of oil. yes? no? any ideas?

Hi,

There should be no need for RTV on the gasket, just some grease or WD-40. Did you use an OEM gasket? As for the oil, did you take off the stator cover while the bike was on the side stand or the center stand?

when i changed it it was on the center stand. when i took it off the second time was just on the kick stand so i guess it was angled that direction. its an oem gasket, it fits perfectly, but its not doing the job at all. all the bolts are in tight and oil is all but running out the bottom.
the gasket is soaked in oil now just fyi

YOU need the gasket !! DO NOT USE RTV If you used an OEM gasket You did not get the gasket surfaces clean. Notice there is a large thrust washer on the starter idler gear !! some of it's clearance is in the gasket !!!

I used RTV on mine, no leaks here.
I just re-used the old flattened gasket, and RTV'ed the rest, lol.

If you take your time, it won't leak, and will get you threw on a pinch.
But yeah i'm just too cheap to buy a gasket, lol.

Pay a little now or pay a LOT later. Imagine how much itll cost if some of that RVT ends up where it shouldn't. Like in an oil passage or your sump pick-up....

With your bike on the side stand (kick stand), all the oil is on the left side.

The stator cover bolts are different lengths. Did you put all the bolts back in the right holes? Perhaps you put a long bolt in a short hole?

You have to thoroughly clean the old gasket off both pieces- takes a while and even longer if someone has used any gunk- and then carefully install the new gasket, making sure that it doesn't shift as the rotor magnets grab the cover.. I used a mirror to check the lower portion to ensure the gasket didn't get distorted before the screws go in.

what about the little D-shaped rubber grommet that the stator wires go through to the starter enclosure? I always force a little RTV to the inside of it around the actual wires before I put it in place.

Solution

ok, i know im going to upset one or two here, but i used a product called 'the right stuff' and it worked great.

if i have learned anything from owning this old man of a bike is that Z1 enterprises is amazing.


my stator is in, but im still not getting voltage to my battery. my rectifier tested good. now what.

[BassCliff]

Hi,

What do your stator tests show? Active AC tests? Passive resistance tests? Connect the stator ouputs directly to the r/r inputs. Connect the r/r ground directly to the negative battery terminal. Clean all electrical connections and grounds. Have a look at my website for lots of guides and other documentation.

Doesn't bother me what you use, but fyi, if the surfaces are properly cleaned and not gouged, a new gasket used, and assembled properly, they don't leak.

I use a product called "High Tack" on the cover side of the gasket. Keeps things from moving during install, and insures that when you have to take it apart the next time, the gasket comes off on the part easiest to clean (IE, the cover, not the engine). Another trick I use if it's a part that will be off regularly, like the carb bowls, or the cam cover, I use plain chap stick on the side facing the engine, or carb body. These two tricks used in combination result in a easy to clean gasket surface, or a tear free, re-usable gasket that sticks only to the part you want it to stick to.

Try it next time you have to pull the oil pan... You will be VERY happy if you ever have to do it again because you will never have to scrape old gasket bits off of the underside of your bike engine again.

Just remember, when you use High Tack, spray only the ONE SIDE of the gasket that you want to stick when you have to take it off later. Never spray it on the parts.
