1500 transmission front cover

2952 Views 33 Replies 12 Participants Last post by  John Beganny
If I remove the front cover from my transmission on my 89 1500 will I be able to determine if something is wrong with the tranny? What will I be able to see without removing the motor? Is this a good idea?

No, Not much, And usually not.

What are you trying to accomplish?
If you've got a 'trans won't shift' problem then you might have a problem with the shift drum plate or the shift drum detents or with the shifter fork. Other than that there's not much else that you can see.

If you've got a 'popping out of gear' kind of problem then it's probably a burnt shift fork and that requires the engine cases to be split.

What is the problem???

This is whats in there... cleaned with a new gasket on it ready to be reassembled.

Not much to see but things can come loose as in the second picture.

The second picture is of my 1100 during a water pump replacement which are internal to these beasts. If you pay attention to the left side of the engine you will see a hefty screw that came out. This is the way I found it when I opened up the engine.

I’d take a look if I were you. It’s easier than removing the engine, you get to see the how the gear selector rotates as you move the mechanics. It’s not hard but a bit time consuming. You will need a new gasket and a few O rings too I think.

1500 trans cover

My wing (89) makes a very loud noise half the time or maybe more and it seems like it is coming from the transmission. If it is making the noise and I put it in 1st gear, the noise almost goes away. If I rev it up in gear the noise can be heard but is much quieter. This happens in all the gears. The motor runs great. I have written all about this on another thread but being new to this forum I don't know exactly where it is.
Your typical trans has no moving parts when stopped in gear with clutch in. Is it a rattle/vibration type of noise? How does it shift?

You need to find out what kind of noise it is (bearing, gear, shaft, crank, piston, valve, clutch, alt, pump) and what is rotating or moving within the engine at the given time.

Mileage and history, when did the noise start, has the engine been apart before?
John, here is your other thread: http://www.goldwingfacts.com/forums/2-goldwing-technical-forum/441386-gl1500-parts.html Hopefully the moderators will merge the two so that there aren't multiple posts about the same problem.

1500 tranny cover

Thanks you guys. It is an 89 1500 with 121K on it. It belonged to a friend who was told by a Honda shop that the noise was in the engine and it was going to cost a lot to even diagnose. So he bought another bike and recently wanted this one out of his garage so he offered it to me for $800. It has a lot of bells and whistles so I figured I couldn't go wrong even if I had to part it out. It has two new tires with less than 500 miles. I listened to it run and it didn't even make the noise when I heard it. It starts right up and eventually makes the noise. I have not ridden it anywhere. I also have a 84 Goldwing 1200 which has been a good bike but I would really like to get this 89 on the road sometime. I am really in no hurry. The 89 sounded good because I am starting to have trouble moving the 84 backwards. Reverse sounds like a wonderful thing to have as my youthful strength diminishes, as difficult as it is to admit.
As I said, I did replace the two timing belts and both adjusters. Using a long screwdriver as a stethoscope I think the noise is coming from inside the transmission but it is pretty violent and whereever I place the screwdriver it is just as loud since it vibrates the engine a great deal. I wil try it again when I get home and borrow a real mechanics stethoscope from my neighbor.

Sorry John, we sort of left you stranded in the other thread. I think you should look behind the cover.
Be careful to record where the bolts come from. They should go back the same way. I make a cardboard copy and punch holes in it to save the bolts in.
Anyway, it seems like you had kind of discivered that it had something to do with the neutral switch. If you take the cover off and there's nothing obvious, post a couple of clear picks here and maybe the 1500 gurus will see something.
If you are careful, the worst that can happen is you will pay for a trans gasket.

To make the whole engine shake the part making the noise has to be pretty substantial. With it in gear and stopped with clutch pulled in no shafts should be turning. Hence no noise at all. No mention of repair history, so.

I would be looking at the other end (clutch), the noise could very well be telegraphing back up to the front on the mainshaft.

Does the clutch lever ever feel different or pulsate when the noise begins. Will the noise change at all with just the clutch lightly pulled. Look to see if the clutch cover/rear cover has been off previously. A possibility at that mileage.

If it had a previous repair attempt for a broken starter/reverse gear which is not unheard of, one has to first remove clutch completely.:?
clutch??

Last evening I attempted to record the noise with the camcorder on my smartphone. I did that but when I tried to send it to youtube I was unsuccessful for some reason. I did observe the following while doing this. The noise was present with the bike in neutral but when I pulled the clutch in the noise changed and I could feel it in the clutch lever. When I put the transmission into 1st gear the noise stopped. As I let out on the clutch and engaged the transmission the noise would resume and get louder as I revved the engine. Is this a clutch problem??? I will try again with the youtube.
you tube

You may now go to youtube and do a search for "Honda 1500 noise". The problem noise does not start until about 30 seconds in so be patient. It was recorded after dark so you will probably see no picture. To make it worse, the sound does not really sound like it does in person. The engine noise is amplified and the problem noise is not. I had not warmed the engine prior so it is revved up because the choke is being used. I will try to do it again.
John,

I was just to your YouTube video and had a listen…

A quick link for others… http://youtu.be/BpwJTSz5cw4

I too had this same, EXACT SAME noise and I hate to be the bearer of bad news but that sounds a lot like the 4th gear issue. That’s how mine ended up before I said enough was enough and replaced the engine with a 97 power plant.

Some describe it as an empty pop can with a few rocks shaking around in it. Mine started off with it doing it only in the lower gears while driving. I never had an issue with it popping out of 4th like some have. That noise will turn into more of a grinding sound.

Mine got so bad I was really concerned that it would lock the engine during mid flight. Not something I would want to happen while riding. Some say that can’t happen but I don’t particularly believe that statement. Take a tooth off a gear or a chunk of steel and get it caught in the teeth of another fast rotating gear… what do you think would happen?

Sorry buddy… It’s engine replacement time.

Tim, Let's say I need a replacement motor. How do I go about that process?
Start out looking on Ebay, there are a lot of Goldwing junk yards around.
Well… Junk yards and bike breakers are one good place to look but I would also put the word out with your biking friends (the Wingers for sure) that you are in need of a post 97 engine.

When I did this I got a lead in about a week and found a great engine that was well taken care of. The bike was in an accident and the frame was bent – not worth fixing.

I lucked out and it was only an hour away so me and 2 of my friends took my van (regular old Ford FreeStar) and picked it up. I paid $1100 for it and that included the engine, carbs, instrument cluster (with proper mileage) and a few other items including an intact latch for the trunk.

That latch was the “cherry on top” in my eyes. Both my trunk latched were broken. http://www.goldwingfacts.com/forums...m/387433-91-gl1500-aspencade-trunk-latch.html

You can also put an ad in Kijiji and Craig’s list.

I have an additional 25,000 + km on the engine and all is good. Good Luck.

noise

This morning I got an actual mechanics stethoscope and gave a listen to numerous things on my bike. That thing is amazing but being a new listener it is difficult to compare what you are hearing to the way it should sound. One thing for sure though, when the noise started, the water pump was extremely loud! The noise may be coming from somewhere else but my bet is on the water pump. That may just be wishful thinking because I do not want to replace the engine if I can help it. I put the scope down on the shifter and in other spots that I thought my be transmission related but the noise was nothing like the water pump. I put a feeler out on another thread for information about where I can get a good deal on a water pump so if you can help on that I would love to hear from you. Thanks.
Noise

I listened to your youtube video, so here's my 2 cents. The water pump would not change noises when you put it in gear. If it's not leaking coolant on the ground, the water pump is fine.
My 4th gear issue was completely different, no noise, downshifted by itself into third under acceleration. Now I know what others meant by "box of rocks" noise.
I replaced my transmission with used parts from Ebay. A very time consuming job. I posted a step by step here.http://www.goldwingfacts.com/forums/10-reference-faq-forum/382857-2001-valkrie-trans-1994-se.html
You'll need to either replace your engine/trans as a unit, or split the cases to replace the damaged trans parts. Either way the engine has to come out. Too bad, the engine itself sounds great.
The noise you hear is the gear dogs and shift forks bouncing off each other and grinding up the mating surfaces, which no longer have the proper clearances to keep them in place. It will only get worse.
Mine has 165K miles now, and I ride it frequently.

As I listened to your youtube video I wish there was more narration. It seems like there are two sounds. One I would describe as a whine. I know belt whine is normal and I am thinking the phone just picked it up a lot better. It seemed unusual but can we eliminate that whine sound?
The rattle was the sound I think you are referring to and only the rattle. If that is the case when the clutch was pulled in and in gear that noise disappeared. Am I correct? Usually pulling in the clutch in neutral will NOT stop the transmission from turning. It will still spin because of friction and the oil sticks the plates together. When you pull in the clutch AND put it in gear the transmission stops and so does half of the clutch plates. I really do suspect Tim is right but I would look at the clutch first before jumping in with both feet. It never hurt to hope but the water pump is not related to the clutch in any way that I know of.

I can't really tell much from that video sound myself. Could be a 4th gear issue starting.

I'm not sure you had a 4th gear issue, not the normal one anyway. There should not be any grinding noise, no reason to have it.
Simply a rattle, then starts popping out of 4th, then no 4th at all.
If you had allot of grinding noise but it was not popping out of 4th then I think you had something else bad wrong with yours.

I have the 4th gear issue, and if like mine it will not have any real grinding sound at all though. Just the loud clackety clack rattle sound. Also if like mine there is no chance of any other problem really than just totally loosing 4th gear. It can not lock up and can not break off teeth or anything similar.
Just the cog does not go inside the 4th gear fully when shifted to 4th so pops back out. No problem, just shift to 3rd or 5th and forget the 4th!
It rattles bad when not in 5th gear because the cog can tap against the fourth gear a little, bit it can not really break off any teeth nor can it go into 4th when it should not.

Near 20K on mine now since I bought it with 4th out, never a problem though I just do not have a 4th gear, and I just towed a 4x8 trailer loaded slightly heavy to CA. and then back with a 1500 on it. All with NO 4th gear and never a problem. Over 2K with the 1500 loaded on trailer, maybe 7K total for the round trip and extra riding.
