DIESEL OIL/ TRANSMISSION CHANGING

[jim c]

HOW DIFFICULT IS IT TO TO CHANGE THE OIL AND TRANSMISSION ON THE YANMAR 18 HP ENGINE? SEEMS LIKE I GET A SIPHON, HEAT THE ENGINE TO OPERATING TEMP, ABOUT 5 MIN, DRAIN THE OIL OUT VIA SIPHON, TWIST OFF THE OIL FILTER AND REPLACEIT WITH NEW ONE BEING CAREFUL NO TO LOSE THE "O" RING AND IM IN BUSINESS....??? AS TO THE TRANSMISSION OIL- JUST SIPHON IT OUT AND POUR IN NEW SUPPLY ?THIS IS A FIRST TIME THING- 50 HOURS ON ENGINE ANY HINTS? SHOULD I CONTACT A LOCAL BOATYARD AND WATCH HOW IT IS DONE THE FIRST TIME?? THX JIM

Call the Mfg for specific instructions

The best answers come from the service dept at the manufacturer. They have the answers for your specific model. Look in your engine owner's manual for the info to contact them. Below is the link to their web page.http://www.yanmar.com/contact/contact.html

Correct

Jim you are correct in your supposition on how to change the oils - but when I bought my boat the dealer said to have the first service done by the Yanmar dealer as this made things much easier should you have a warranty claim. Also I believe they torque up the head bolts, re tension the alternator belt and probably do other checks such as tappets etc.

Pay for the first service!

Jim:You are right in paying for your first service as long as you are there and get some tips on doing the service. Make sure that you get a Yanmar mechanic and not just a marine diesel mechanic. These guys work on these engines every day and know all the little tricks. You can learn how to change the oil, filter etc. They will also show you how to bleed the fuel system which is important should you ever run out of fuel.

Three things

1. When hiring the Yanmar mechanic, use a small tape recorder to get his instructions down pat, then transcribe accordingly. A nuance or trick missed in your attempting to take notes could prove troubling.2. When constructing your pump, try to use a foot-long piece of brass or copper pipe that will not curl as it reaches into the bottom of the engine. That way you'll get more oil out.3. Having said that, you're still unlikely to get more than a liter out, and it takes more than that. So the trick is to change your oil once a month, with the effect that you're actually changing it ALL every two months.
