This ones glued on or something. Bikes a 77 gs750. Ive checked, triple checked for any bolts i may have missed, tried getting a putty knife in between cases and the block.....and its not coming loose. Suggestions. Ways to set up something to maybe spread the block from the cases? Any photos of your homemade tools would be great. Thanks.

Maybe the pins need some penetrating oil? Can you squirt it down a stud channel?

Penetrating oil down the stud holes sound like a good suggestion.Ed

I put PB BLASTER heavily down stud holes before closing down last night. I also made some aluminum wedges and will try tapping those in to see if I can get the seal brokeMY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

Mine was tough too, I tapped front and back lightly with a deadblow hammer and worked it free that way.Comment

There's a flat spot on the crankcase and a matching one on the cylinder block at each end, find a 6mm bolt or cut one to length and put a nut on it put it on the flat spot and unwind the nut it will break the gasket free and the rest is easy, move it to the other side if necessary, but I've never needed to. I think it's even in the manual or there's a tool that does what i describe. Here:

But a nut and bolt work every bit as well if you put it on the flat of case where the engine bolt hole is and simply unwind it.Last edited by tatu; 09-04-2020, 04:09 PM.sigpic
Don't say can't, as anything is possible with time and effort, but, if you don't have time things get tougher and require more effort.Comment

So it was glued together. That's fine if you only intend to do a head and valve job.
I like you're making aluminum wedges just for this project. Way above the imagination of the average mechanic.1982 GS1100G-

Well Bill, the thinness of a 1/8 thick aluminum wedgewill one of two things. Either wrinkle and fold up right from the get go or work itself in. they peeled a little going in but supplied enough opposing force to get the gasket torn. And i mean it literally shredded with chunk stuck on the cases and the jugs. Stuffed rags around all the con rods and a good sharp chisel did the rest.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)
