Ok, I have another thread running here on the rebuild of my 1985 VT1100. I am in the transmission and found a badly worn shift fork. The middle shift fork. Gears all look great.
Now I am confusing myself with the diagrams I have found. The diagram in the Haynes book I am using shows a thrust washer on the left end of the counter shaft and the main shaft. When I pulled mine apart it did not have a thrust washer on the left end of the main shaft, but DID have one on the left end of the counter shaft.
I looked at the diagrams on Bike Bandit and a few other Honda parts websites. These diagrams only show a thrust washer on the left side of the Main shaft.
The instructions in the manual state "Don't forget to install the end washer on the left end of the main shaft (you should also have an end washer on the right end of the countershaft). That is printed under one of the illustrations. ALso in the reassembly instructions it says do not forget the washer on the left end of the MAIN shaft. It does not say there should be a thrust or end washer on the left end of the COUNTER shaft. The schematics on the parts sites only show the one thrust washer (20mm) on the left end of the main shaft, nothing on either end of the counter shaft.
So, what is right? This bike looks like it has been apart before. There is evidence of RTV silicone on places that should not have silicone gasket material. So, I am assuming it has been pulled apart before. So, does anyone know on a 1985 Shadow 1100 where all of the thrust washers should be? I don't want to put it back together the same way it came apart, the manual says an end washer must go on the left side of the main shaft. I feel that may be the cause of the shift fork wearing down on the right side.
So, any mechanics or anyone else that may know how this should go back together, your input would be greatly appreciated. Should I go back together the same way it came apart, or the way the manual says? If so, no parts schematic shows an end washer on the right side of the counter shaft.
I am so confused!

Since it's the Haynes manual they show a few different 1100 engines ...are you sure you did not confuse it with a different year... they are a b*tch for that


What page are you looking at I will read mine also.

That is what I have been thinking. It does show the 5 speed, which 85 and 86 are the only years with the 5 speed. After that they went to a 4 speed.
Someone on here has provided me with a link to a better manual that I am going to order, I just haven't ordered it yet.
I am thinking I will go with the parts schematics I have been looking at. Bike Bandit, and some Honda specific parts dealers websites have shown the washer on the main shaft only. No parts listed for thrust washers on the other shafts.
I am hoping a better book will give better details, but thought maybe someone on here had been into one of these tranny's before and would know.

Go with the parts diagram. Haynes are only general reference tools. I wish they did a better job but they don't. Sometimes though they have good ideas on how to take something apart.

Thanks for the tip. I am definately ordering a better book, but until then I am going to go with the parts schematics. At least for ordering parts anyway. It looks like I can get away with just a new shift fork and gaskets. Going to re-ring it while I am in there.

Re-ring the cylinders?

Measure them and hone them too, otherwise your new rings will never seat properly.

Thanks for the advice on replacing the rings. I have been a certified auto mechanic since 1989, for the past 15 years have only been shadtreeing it. Although I never realy messed with bikes until now, except dirtbikes, measuring and honing is all part of re-ringing anything. But, I realy do appreciate the advice, and that there are people out there that are willing to offer free advice to help a guy out.

Ah, no worries then! You'd be surprised how many times I've seen someone tear an engine down and then say, "Hey! New rings were only $50, so I put new ones in." Yeah. New rings and nothing else. That's a rebuild, right?

My thoughts exactly. that is why I was seriously saying thanks for that little reminder! I have seen people do some things like that with car "rebuilds". Change the rod and main bearings without checking the crank, change a valve without even thinking about grinding the valves or checking the seats, and many other cheap shortcuts.

Oh, and where do I find a set of rings for my bike for $50? So far what I have found has been around $85.

I haven't been able to order a manual or parts yet either so kind of hangin out for a little bit.

I finally located a OEM OFFICIAL manual and am tracking it online now.
When it warms up and you get back to working on your bike.
When I receive my manual and you need answers I will gladly scan the page you need and email it to you.

I could definately use a scanned image of the pages covering the transmission. Especialy anything that would show the thrust washers and their placement on the main and counter shafts.

Hey DepDawg,

I have the genuine Honda manual. I'll try to scan the correct pages and either post them here or send them to you tomorrow.

My trans pops out of 3rd under hard acceleration, but I've heard new shifter forks or new gears to fix worn geardogs are no longer available.

Good luck with your repair. Hope I can help.

That would be great if you could scan and send the pages that cover the transmission. I am pretty sure the bike bandit schematic, and the schematic on the honda parts sites would be correct on the thrust washer, but keep second guessing myself. It is a lot of work to tear it down just to move a washer if I am wrong!
I think I dodged a bullet, the gear and gear dogs look good. I can see no wear at all, not even rounded edges. The only wear I see is on the shift fork, and it shows signs of some serious heat. Either run out of oil, or the thrust washer was put in on the wrong shaft causing everything to ride out of alignment. From all I can tell it has been torn down before. Probably why the gears look so good, they have probably been replaced.
Anyway, the pages would be much appreciated. Thanks again!

Hey, I sent you my E-mail address through PM. After I did that, I checked this post and saw your links to the pictures. I was able to save them to my hard drive, and get a real good look at them. I think I got my problem figured out. Thank you very much for your time and trouble helping me with this!
It does look like someone before me had this transmission apart, and put the thrust washer on the left side of the counter shaft instead of on the left side of the main shaft like it is supposed to be.
Again, thanks a lot for your time and help!
