I replaced the chain on my 190e 2.3 and I'm wondering if I reinstalled my tensioner correctly.

I completely disassembled the tensioner and cleaned it up. When reinstalling, the book says "Push setbolt (37) and locking spring (38) into the assembled chain tensioner casing." I pushed the setbolt / spring in and tried to install the cap but it seemed as if there was too much pressure to get the cap on. So I tried to push the setbolt in further and it seemed go in another 1/2" or so. I was then able get the sealing cap on. Is this correct or is it possible to push the setbolt in too far?
