oil seal?

[Eddie]

ok sorry im posting so much , but it seems as though everytime i ride the gt750 I find something else wrong! anyway since im waiting on the airbox stuff, i have been riding it around but not much, yesterday I rode it and when i put it up, i noticed around the starter cover on the left side of the bike it was wet, but I cant tell if it is radiator fluid or something else (gas) , so I had posted this in my other thread on the carb jetting, so since this is different I re-posted it here. I hope the hose that goes under the starter cover isnt leaking? its a new hose and im sure its tight, so maybe its the fitting that the hose connects to, im not sure, then I noticed that there was oil and fluid coming out of the side case where the shifter is, so i took the side cover off and noticed that the gear indicator was full of greese oil water whatever, so I think the oil seal behind the sprocket which is above the gear indicator is leaking, my question is , is there a seal behind the indicator? I will need to replace the seal behind the sprocket and the shift shaft but i did not know if there was one behind the gear indicator? and i couldnt tell in the book? also I checked the rad fluid and it was slightly low but nice and green color...

The gear indicator has an o-ring in the face that mounts to the motor. They rarely leak unless it's cracked or loose. Is yours plastic or metal?

[Eddie]

mine is plastic, I cant tell if its leaking from the indicator or the counter shaft, it looks like oil mixed with rad. fluid? have no idea how that is? the tranny fluid looks ok, but the rad. fluid was a little low...how hard is it to change the shift shaft seal? I havnt really looked at it yet just wondering if its a pain..

Being you posted of leak prior and you stated that you replaced the hose. You could have a leak from your vertical coolant hose connections. It could be leaking down or around the starter cavity. There is hole in that cavity for the SRIS hose to run up through. The coolant could very well be leaking down to your gear indicator through that hole. Causing you to think there is a problem with the gear indicator or shift seal. The coolant hose connections have to have Teflon tape around both threads or they will leak. Yes, there is a rubber o ring behind the gear indicator as well that could be hardened. Remove your sprocket and gear indicator and thoroughly clean up under the sprocket cover to monitor problems. 35+ years of poor maintenance has come to this. I had a couple of days tied up in cleaning that mess.

Thanks pearljam, thats what I was thinking , but I wasnt sure I couldnt remember what it looked like, I replaced the hose in there but I cant remember if I put teflon on it or not? im getting forgetfull (bad) both of my daughters have been complaining that I forget alot now, maybe there right crap.... what do you mean on both ends? I remember the fitting that screws into the case and it is threaded on one side, so what other side? I sure hate to drain coolant and take carbs off to check!!! its weird that it just started doing this? if it was leaking from the hose fitting I would have thought it would have done this before? I think I should see the doc about meds for my mind and not my pennis(viagra) , blood is flowing in the wrong direction...

[Eddie]

also do you have to take the starter out to tighten the hose fitting? that would really suck!!! because then the oil lines have to come off!!!!!! craaaapppp!!!1

[pearljam724]

Oil lines don't need to come off. Neither does starter if you have a deep well socket. Only the cover and carbs. There are two fittings. One on each end of the hose. If you ever removed one of those fittings. You would have to Teflon those threads. If you didn't loosen the fittings. That is not you're problem. But, being you just replaced that hose. I'm willing to bet it's that or the hose clamps. I can't think of anything else that would cause a coolant leak there. Plus, it's too ironic. Draining the coolant on these bikes is painless and quick. There are 2 drain plugs located at the lower left of the motor that makes it a breeze. Unlike other bikes, it can be a hassle. I would suggest cleaning all areas very well and keeping a close eye to find out exactly what is going on.

Thanks again! I know its not that hard but it sucks having to go back in there!, my fitting was a one piece fitting, i did not see two ends? or two pieces, maybe the p.o. changed it? im not sure i will look up a diagram of it, the guy I bought the bike from sure had it rigged!!!! I replaced so much stuff now its crazy!!!! well i hope its just the hose or the fitting needs teflon, but I think your right, its leaking from that hose or fitting and then draining out the hole and going into the side cover area... thats what it looked like anyway, I will plan a day to take it apart and see, I need to put the newtronics system on it, so when I do that I will check all this stuff out at that time. Thanks again for the help!!!!!!!!!!!!! I havnt had much time for anything lately,

[pearljam724]

You're welcome. You need to learn to slow things down a little. It sounds as if you're hurring to do this stuff. Slowing down often saves you more time in the long run. It sounds that you understand how important maintenance is and you're willing to put that time into into it. And learn more of it. Which is good. Keep at it.

[Eddie]

Your right about being in a hurry, I don't like to do any mechanical job in a hurry , iv learned a long time ago it just causes more work.,, although recently it seems that I have had very limited time to work on it, and when I do , I only have a couple of hours, I work out of town a lot and i have had medical issues to deal with, but that should be no excuse but I just wanted to ride before I may not be able to, but I am pretty sure I put Teflon but not totally sure, I replaced the hose then I moved on to another issue and by the time I got it back running I just can't remember, I had a list of stuff to do to it , and it all got done around the same time...

Mine looked like that too. I found that the bushing between sprocket and shaft bearing that the sprocket seal lip rides on was warn. Found it when performing pressure testing of crank case. It looks like dirt sands the metal and causes a groove at the seal point. I flipped it and proved the seal would not leak anymore. Part still available

[Eddie]

Thanks for the info , I will check that bushing, but like pearljam said , I need to slow down and take my time like I used to, I really dont like to rush, Iv just had alot going on, and to be honest Im surprised that I have even worked on the bike, people think Im crazy just cus im making time to work on it, but its a passion to work on stuff and its good therapy..

You're exactly correct. That's how I feel about working on bikes. I've always been a bike maintenance nut case. With these bikes, there's something about keeping them running proper, improving what is there and keeping them around so to speak. With the rebuild I'm doing. There's something about resurrecting it from near death and giving it that past life that is very therapeutic for me. I'm sure many others feel the same about these old 2 strokes. I had a teenage kid literaly chase me across a gas station parking lot the other day to see my bike. He said, " He just had to see it when he heard it from a far. " Because his dad always told him stories of them. He was totally amazed, Lol ! That kind of stuff is very cool to me. It's usually the older guys. But, he new exactly what he had heard and seen. Good share, Vintageman.

[Eddie]

I just read your reply pearl jam, that's exactly how I feel about old bikes, I don't need to be the fastest or the loudest, I just like to ride unique bikes that you don't see every day, or bikes that help you remember your younger years! I love it when people just have no idea what the he'll your riding, I had a cop ask me where I bought the gt750! I got pulled over for speeding, but I was like five over the limit, he just wanted to see the bike, he thought it was new! When I told him it was a 74 he couldn't believe it!!! Thence got kinda sad cause I wouldn't sell it....

[Eddie]

well i took it all apart, and I had not put teflon on the water hose fitting! so im glad I took it apart, although it did not seem wet or anything in there, maybe the water drained out the side like mentioned before, well one thing is done and now on to the shift shaft seal and im waiting on parts , I ordered all the stuff that fits behind the sprocket, bushing etc... I think this is where the leak is for sure, so thanks for all input..
