If anything like the B50 engine removal procedure (which is a tight fit), it is far easier to keep the bike upright (you can see what you're doing, plus the engine really isn't all that heavy - B50 is about 85lbs, I guess the Triumph lump, if primary drive is off, as it should be if you're doing a full engine strip, would be no more).
It's a case of shifting the engine and pivoting it fore & aft, until you can see how it will come out. Sorry, no better way to describe it. But be sure it is possible - it got in there! Maybe remove the rocker boxes if these seem to be restricting pivoting movement?
If anything other than a blank space is visible here, something's wrong.
Thanks. The bike is back on the lift now and strapped down. I thought I'd try the lay-down method to spare myself some of the heaviest lifting, since I kind of wrenched my shoulder lifting the A65 motor into the frame two years ago. Guess I should be careful and get some help with the lifting.
Rocker boxes are off. Full strip and rebuild to crank is inevitable, although when I first got the bike earlier this year I thought I'd clean up, tune up, start up. But seeing the molasses-like oil that I cleaned out of the "tank" I knew that I had no choice. I was avoiding complete teardown at this point since I get kind of anxious if too much is apart at once.
Maybe not going to be a lot of help, but I didn't strip the engine down at all and I kept the bike completely upright when I removed the engine from my TR5T. The frame was completely stripped down as I had to get a crack if the frame repaired. Again when I put the engine back in, it was fully assembled, with the possible exception of the clutch. Unfortunately, this was a number of years ago and can't specifically remember what I did, but don't recall any problems.
Thanks. Bike is strapped onto the lift again. I've been sorting the parts that came with the project, the PO kind of included lots of odds and ends, but I've got it sorted now. Will have another look, maybe I'm missing something still
