1981 GL1100 Engine Removal

Postby cooperbergh » Tue Jan 24, 2012 2:08 pm



Hello all,

I am in the process of pulling out the engine of an '81 GL1100 and giving it a quick overhaul. First GL, so I am wondering if anyone can provide a link or a "how to" to pull the engine. Carbs are out so far and I stuck at the drive train. It looks like it simply pulls out but that seems odd to me. Any help would be greatly appreciated. I am sure I left some things out, so if you need any more information, please let me know. I can also take pics and upload upon request.

Best regards,
Coop

The drive shaft,swingarm and rear wheel stay on the bike.
Remove the spring that retains the rubber boot on the rear of the block and push it back.
Using the proper "C" clip removal tool,Remove it off the output shaft of the engine.
the driveshaft will just about wiggle off.
You can remove the engine from there.
Just remember to get it started back on before you try to bolt the engine back in.
What is involved with your "quick"overhaul??It sounds like your preparing for a major rebuild.

Thanks for the reply. I appreciate it. I just purchased the bike. It ran for a while before it started leaking oil pretty bad. It had to sit for a few months until I had time to work on it. Now I have the time and more than likely it is just a gasket seal that needs to be replaced.

Well,the block dosent have a gasket on the split case,so I would look where the leak is coming from.
The rear cover does have a gasket and the engine has to be removed to replace it,however most leaks come from areas that dont need the engine removed to service,like,the front cover,shifter shaft oil seal,water pump oil seal,head gaskets,etc.

That's good to know. I want to set the tone that I am new to motorcycle repair however, I have friends with much more experience helping me. Your insight is greatly appreciated.

My description of the problem (very telling): The oil is leaking from a hole in the bottom of the bike. It seems to be coming out of an inlet on and/or around the oil filter itself. I replaced the oil filter module completely and am still having the problem. I took many pictures and showed them to some mechanics at my local Honda dealership. Both places said I would have to drop the engine to get to the problem which would more than likely be a seal of some sort.

This feedback is what led me to start taking it apart. I can take pictures and post them here if that would be helpful.

EDIT:: My buddy said that the issue could be the water pump oil seal. Can this be changed/looked at without dropping the engine?

Best,
Coop

Yes,do post a pix.if it is leaking oil from a small hole on the bottom ,kinda under the radiator hose area,it will be a bad bearing seal in the water pump.And yes it can be repaired without pulling the motor.

Thanks for the feedback! I will stop pulling the engine for now. Any insight into how to get to the bearing seal? I am searching through my old hard drive to get the pics up soon.Else, I can get more on Thursday.

If this is the hole it's coming out of:

Then yes, that's your water pump that's the problem. The easiest way is to just replace the water pump impeller (the seal is integral to its bearings), as well as the oil seal on the driven shaft (it comes with the water pump gasket kit). The entire procedure is detailed here: How to remove and replace your water pump

That looks like my issue all right. The only difference is that oil is coming out and not coolant. Same area though. Crossing my fingers for the same solution?

Yes. See the diagram below - if the coolant side seal fails, the coolant (blue) leaks out the weep hole. If the oil side seal fails, oil (green) leaks out the weep hole. In either case, replacing the water pump impeller fixes the problem.

Thanks for the help. This will be fun. I found the water pump seal kit online and am now looking for the water pump itself. It looks like I will have to go with OEM. Again, much thanks and I will post pics of the process along the way.

What ever you do and whoever you order your parts from myself and MANY other people would recommend you stay away from Saber Cycle .

The water pump is an easy change out , see this forum has already saved you money and time. You just gotta love these people here.

Best on line prices..I have found http://www.westernhonda.com but you can rebuild these pumps there's a guy in Holland who sells the whole kit for $25?? or so her's his email rainer1...at....proebstl.net edit back to the @ sign. just want to post his email intact.

You can tell if you pump is bad by just removing the front elbow..drain the water now you can see the impeller if you can move it side to side or up and down AT ALL..it's going bad. If it's solid it just maybe your oil seal is bad..with that said, with t it all apart to replace the oil seal is the same process for replacing the pump..and it is 30 years old.so even if the pump is solid you might want to change it out.

The water pump is one place where you DEFINITELY want to buy OEM.

Hey guys, I'm back. It's been a while and I am finally in a position to pull the trigger and get this thing done! I'll be taking everyone's advice here and will be doing repairs over the next 2 weeks. I'll post pics as I make progress. Any particular pic requests for future uses/guides?

It's always nice to see before and after pictures.We usually see completed bikes.
I'd like to see the oil leak area,how bad it looks and what it takes to fix it...then the well done job.

Are you replacing the pump with OEM? If so, it should be good until....er...2043, based on the life of the original! :shock:

I have taken most of it apart already - been sitting in the garage for a little bit. Will have to find older pics I took. Will also take pics of after as well. Decided to get take off head gaskets so I will be getting seals on there. Also rebuilding the carb. Pics and links to come.

Would have loved to save some $$ on the pump, however everyone said I should go OEM. Plans are to head to the dealership (boo) this week to get pump and parts. Will probably be spending ~$60 more than if I shipped from online vendor. Also entertaining the idea of rebuilding the pump as it seems fairly intuitive - hardest part seems to be find the parts.
