Interested to know how you can remove the chain without removing the tensioner. Pulling like heck on the chain to get it off the sprocket?
Removing the cams is no big issue, once the top chain guide is removed, and the exhaust cam caps are removed, that cam rotates freely and slides right out, just as will the exhaust cam... the issue is getting them back in place correctly, and snugged down timed correctly, without the tensioner clicking out ......
I've pulled the cams without removing the tensioner, but prior to reinstall, I pull retract, and reset the tensioner, and insert it once the cams are in position, snugged down, and all looks correct... even then, when inserting it the tensioner tends to release prior to seating, requiring some force to get it in there.
