Topic: Trouble re-installing heavy duty cylinder studs

[scondon]

    As the title says, I'm re-installing my APE studs into a new case. If memory serves, the end with the longer threads goes into the case, shorter threads up top. I can't get the studs to start threading into the case. The short end threads into the case, no problem, but the long end won't even get past the first thread. The thread pitch on both ends seems the same since I'm able to install the nuts on both ends.

  I guess my question is, long end goes into the case, right?

Right, longer thread in the case. Not sure about those, but I have had some that claim the end that threads into the case may have a slight oversize pitch which could be your issue. Maybe a little bevel dressing will help?

That's what I'm thinking. I'll see if I have the right size thread chaser, oil up the studs, and try again. Just needed confirmation that I was on the right track. Thanks Brent, check yer mail

Brent you nailed it ,make sure holes are clean !they will only start,(barely)until you start to torque(turn) them,just did Drew's bike 2 wks ago just takes a little time.Good Luck,Bill

Thanks guys. I don't remember these being so tricky to start. Last couple installs were tight, but easy enough. I'm having to be extra sure that I get them started straight on the first thread or two, but they're going in easy after that. 3 down, 13 to go. Can't find the APE install sheet, but 8 ft/lbs torque into the case sound about right?

Thats the max,Good Luck,does take a little time,but well worth it!,Bill

Thanks for posting the sheet, Nippon   Apparently I've installed them exactly to spec

joeb- hope to have ya over soon for the ol' "heave-ho" into the frame. I've got a Labor Day trip planned and need this bike up and running.

hey scondon- i always clean up the threads first, with a thread chaser, making sure to clean with solvent and blow out all the mess afterward of course. using grease on the tap helps a lot, as it catches most of the shavings.

[scondon]

If I'm going to continue putting engines together I have GOT to get a proper set of thread chasers Thread taps just don't cut it. Well...actually, they do, which is the problem

This worked for me, saw a slot in an old one, it chases rather than cuts, then clean and blow as paulages said

I forgot all about that nifty tool. Thanks for reposting it,Gamma. I'm going to go make one right now, for next time.
