Re: I was Bored so Pulled the Head on my Yanmar

So below is a before and after of the engine compartment. After cleaning the bilge of 19 years of "stuff" I'm guessing that nice coat of oil /tar protected the epoxy paint under it.

Oh the wires hanging down are the temporary ground while the engine is out. I use a bolt on the engine (well the original owner did) as the ground point. So I had to sort of tie the battery banks and panel wires together.

It will all be zip tied back in place once "Purple" the engine is reinstalled. Also have a new exhuast hose coming too, just have to remove the old one from the water lift muffler... gently.

Pondering replacing the packing in the packing gland. It's only 4 years old and is the good graphite tefflon packing.. pretty much dripless. I have another set precut. well have had for 4 years. Thinking now would be a good time

Off in a while to pick up the block from the machinist.... It's Ready!

Re: I was Bored so Pulled the Head on my Yanmar

It's BACK!

My Yanmar 3GM30F engine block is back from the machinist. Photo below. Guess which cylinder is sleeved. A very nice job.

PLUS... my parts came in today too. The second photo is what $700 in official Yanmar parts looks like. Its not that big of a box either. The two engine mounts to the right of the box was just about $300 for two. Ouch! I noticed that while Yanmar engines come with two chromed rings, the genuine Yanmar replacement parts, only comes with the top ring chromed. Looks a little aftermarket ish to me.

I did not order many of the smaller gaskets, like for the lift pump, etc. Those I'll make from gasket paper and save a few dollars.

I should also note that I was charged twice for shipping, A total of $58 dollars. Shipped once from the distributor to the dealer and a second time from the dealer to me. I understand this is pretty standard for yanmar.

From a parts cost standpoint, a standard piston / rings set was $95. First oversize was $150 ish each. Rings alone were $55. Big end bearings were only $5.39 per hole, a bargain. So not that bad overall except for the engine mounts.

I want to thank those of you that made generous contributions to the Sailorchic34 engine repair fund. Without those donations, I would not be this far along today. Bless you!!!

Tomorrow starts the assembly with checking ring end gags first. I'm so excited... With a little luck, I'll have it all back together and installed within two weeks. That's my goal anyway. Happy Girl!

Re: I was Bored so Pulled the Head on my Yanmar

I'll be quite happy if I get 6000 hours on the rebuild.

Well cleaned off the cylinder walls. Used paper towels at first and then switched to toilet paper, per a suggestion from someone here I think. Boy that works really well.

Plus the block is painted too. After first coating the rusting spots with phosphoric acid. Looking good..

Re: I was Bored so Pulled the Head on my Yanmar

Today starts the rebuild process. After cleaning the bores of honing stuff yesterday and painting the block purple, this morning started out slow.

First I had to remove the rings and check ring end gap in the cylinders. I checked an old one too and both the old and all the new rings came in at 0.013". Stock is anywhere from 0.008 to 0.015 so right in the middle. Wear limit is 0.059" which is a lot.

So reinstalled the rings, used snap ring plyers to spread the rings. That worked well enough.

Then reinstalled the crankshaft and touque the bolts. Then install the crank timing gear, govenor weights and the special nut. Put the cam tappits back in, which go in from the oil pan side before the cam goes in. I used a magnetic pickup thingy to guide the tappits into their respective holes. That worked well. Installed the cam, checking that the marks on the crank and cam gears lined up.

I reused the crank bearings as the front one came in as stock on wear. Plus it takes another special too to remove the end bearings and I have had it with yanmars special tools.

Then installed the pistons. I did not have a ring compressor. But I had a small metal band type oil filter wrench that actually did a quite respectable job as a ring compressor. Just the right size too. Always love it when a tool has more then one use. Cool.

Its lunch time and I need a break for an hour or so after 3.5 hours working on the block.

Next will be installing the oil pan, timing cover and injector pump. Then flywheel cover, flywheel, head and odds and ends. Its looking like I'll have it together by tomorrow sometime. If all goes well...


Below the results of 3.5 hours of a blonde mechanic. Plus the cockpit is a mess which I so love.... Not. But I'm saving a massive amount of money that I don't have, just in labor rates. So pretty happy all in all that things are going so well.

Re: I was Bored so Pulled the Head on my Yanmar

Won't be long and you will be rounding up a muscular crew to assist in moving the engine into it's clean nest. Looking really good so far. How are the pink accessories coming?

You know, I was looking at the external oil lines and HP injector lines today. Got to clean them up and get the rattle can of hot pink out. I was wondering what I was going to use that can of pink paint on. Really had no clue when I purchased it. I think it (pink oil and injector lines will work with the purple.

Exciting!
