Splitting case to get to pistons

Post by Paulwilliams » Thu Oct 16, 2014 11:16 am

I know this isn't what you all are talking about, but I don't know where else to find help, so I'm hoping that you can help me for two days now. I've been trying to find out if you have to split the engine on a gold wing 1000 GL 1000 to get the piston and check the rings. I hope I've said this right. I'm doing this for my husband and I don't know who else to turn to. Still hope some of you guys out there can help me. I found places where it talks about what to do after you get it out, but not if you have to split the engine to get it out help help I need help

See the Clymers Service Manual. It explains the procedure. The engine will come out of the bike intact, but you will have to split the case to get the crank and pistons out of the block. You should open a thread of your own detailing your problem rather than jump in on some one else s thread.

Yes after the motors out you will have to pull the heads and then split the case open.The crankshaft is bolted to one half(I'm thinking left hand side,but it's been a while)so you basically lift the right hand side and slide it off of the two right hand side pistons.Then you can unbolt the connecting rods off of the crankshaft and slide the left hand pistons out.That's the easy part.The hard part is sliding the RH case back down over the pistons for reassembly.
BTW If you look at the top left of this page you can download a manual for your bike if you don't already have one.
If I'da known it would last this long,I'da taken better care of it.

Whoa, slow down. Let's determine why you need to "check the rings". What problems are you having that make you think need to do this?

I agree that you may want to slow down a little before taking the engine out and splitting the cases. These flat four engines appear to be pretty darn tough and can go a lot of miles before a "major" overhaul.

I found manuals for 1100's 1200's and several supplemental manuals available for downloading online... so you may want to try that route before doing a tear down. The copy of the Honda Shop manual I found is very comprehensive for troubleshooting and repair. Unfortunately, I don't have one for the 1000 models... haven't needed one yet.

There's plenty of GL1000 riders here, and many of them are pretty smart about maintenance and repair on the engines. Let the group know what you perceive your trouble is, and maybe one of the members can help you fix what's wrong without splitting the cases... if it HAS to be done, you can always go that route. Oh, and welcome to the site... there's lots of information and helpful folks here.
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

I agree splitting cases is a big deal..yes you have to it to get to the pistons. But why like everyone said what's the problem???

I'm sorry it is taken me so long to reply to everyone. I set this account up in my husband's name, but he is 73 years old and thinks computers are evil. So I'm the one that's always on it and always looking to answer questions for him. I just barely got on to Gold wing docs and am still trying to figure out how to use it. We did get the engine split and did check the Pistons and replace the rings. I guess the reason you wanted to do it was because he wasn't getting the compression that he needed. Thank you all for the information that you gave and again forgive me for for taking so long to reply
