Refit:  Winter 2008-2009


Winter 2008-2009 Refit | Saturday, November 8, 2008

I reassembled the LPG regulator bracket assembly, now that the rusted pieces were nicely painted and cleaned up, and prepared to reinstall it on the front of the doghouse.  First, though, I removed the remainders of old sealant, then cleaned off the rust streaks from the rusty bracket.  This made me feel immediately better.

Then, I installed the bracket with sealant and screws, as before.


         


Next, I cleaned up the now-cured excess sealant from around the new galley sink; I'd been weighting it down for a week while I waited for it to cure.  The excess cleaned up quickly, and the new sink job was complete.



It was time for some basic engine maintenance.  I changed the oil and filter, replacing the filter with Yanmar's new filter that satisfies the original part number; the new filter was quite a bit smaller than the old, which worked to my advantage since the clearance between the filter and the nearby alternator is very tight, making it nearly impossible to get a filter wrench on the filter.  The new, smaller filter increased the clearance by 1/4" - 1/2" beneath the alternator, so replacement next time ought to be easier.



Next, I changed the two primary fuel filters.  I have two filters because I received a new filter along with my new Yanmar back in 2001, and at that time I decided to simply install the new one in series with the identical one that I'd installed to service the old engine.  Excess filtration is not a bad thing, though if I hadn't received the second one with the engine I wouldn't have seen a need to install two in this manner.  In addition, there's an engine-mounted secondary filter, whit takes a small  micron element from Yanmar.

I run a 30 micron element (red color:  Racor R15P) in the first primary filter, and a 2 micron element (brown color: Racor R15S) in the second primary filter.  I had one set of spares remaining, and I installed them both and noted the need to order some replacements.



Here's proof that filtration works.  Below are containers holding the fuel that I drained from the two primary fuel filters.  On the right is the fuel from the first primary filter, the 30 micron unit through which the tank's fuel flows first.  On the left is the fuel from the second primary filter, the 2 micron unit, which comes downstream of the 30 micron filter.

Clearly the fuel in my tank is getting a little nasty, so it's time to clean that out.  Nevertheless, the filters are doing their job extremely well.  I must admit that I had not changed the fuel filters since July 2007; the 2008 season was so minimal that I just never got a chance to do this basic chore (plus it was easy to see that the fuel in the second filter's bowl was clean and clear).



Total time today:  2.25 hours
