ri702bill 11,545 #2 Posted Tuesday at 04:44 PM Since they are all simple black iron pipe components that are readily available, why not just go with new pieces?? 1 4 Share this post Link to post Share on other sites
rmaynard 16,992 #3 Posted Tuesday at 04:52 PM Since those three pieces now cost about $16.00 here in the U.S., he might be wanting to save a couple bucks. 1 Share this post Link to post Share on other sites

But is it really worth the aggrevation to remove the fittings & you usually need to crush the block nipple anyway to get it out. All the carbon packs the NPT threads for a "lifetime" fit... I would think that inch sized pipe & fittings would be available up there ... 3 2 Share this post Link to post Share on other sites

I may be able to them fine from a local store - do I need any glue or just tighten the pipe to the engine? Share this post Link to post Share on other sites

ri702bill 11,545 #7 Posted Tuesday at 07:39 PM No glue required! Just a pipe wrench. Those are tapered threads that "lock" when tightened... 2 Share this post Link to post Share on other sites
oldlineman 1,658 #8 Posted Tuesday at 09:43 PM That's what I was thinking, I would buy new and not take the chance of damaging the old block if you were going to save it. 2 Share this post Link to post Share on other sites
Lee1977 7,627 #9 Posted Tuesday at 09:59 PM After been on there around 50 years. it's not likely they are coming apart without damage to the block. 4 Share this post Link to post Share on other sites

If you're trying to remove from top pic motor and use on 2nd pic motor the juice is defiantly not worth the squeeze . Share this post Link to post Share on other sites
gwest_ca-(File Mod) 12,068 #11 Posted 7 hours ago See if you can find an electrical conduit lock nut to add to the fitting before you install it into the block. Install the fitting as far as it will go into the block and then back it out at least 1/2 a turn so the fitting is loose. Using a hammer and punch now tighten the lock nut against the block. Fitting is now tight. If you remove using the reverse sequence once a year it will likely never be seized again. I always apply graphite to the threads as it seems to help. What the lock nuts look like available from Home Depot or the like. They are available for all common pipe sizes. This is a procedure I learned from a small engine repair shop that serviced thousands of small engines a year. It was part of their regular service. 1 Share this post Link to post Share on other sites
