Remove Steps for engine service?

[papawads]

Hi guys, I’m going to do much engine work over the next 2-3 weeks.  Do people commonly remove the steps for some of this?  I can see they’re hinged with removable pins, but are there any secrets to pulling/returning them?  Thanks
:-)

I often removed the steps for easier access. It is best done with 2 people since getting the pins back in can be a bit finicky and it is easy to scratch to floorboards if one is not careful. Removing the pins is easy (it helps to put a drop or two of light oil on the hinges), remove the split pin with needle-nosed pliers and if they don't slide out you can tap them out with a small screwdriver and hammer.

Same for me with the 42DS. I can do it by myself but much easier with 2 people. The 42DS is restrained by a piece of line with a stopper knot on the end. I undo that first as it's easier to manage before removing the pins. I usually undo the bolts, remove the pins, sit a mat underneath and lift the bottom outwards to slide to the floor. We normally lift it to another mat in front of the cooker. I also take the opportunity to lubricate the pins when reassembling.

My pins have metal loops rather than split pins.

It's a pretty easy job on the 42DS and allows very good access to the engine. I imagine the 43DS will be pretty similar.

I, too, have cotter rings securing the pins on the 36i.
First I remove the stopper knot from the restraining line, then I will close the engine cover, pull the pins, place a protective mat against the base, and lift the entire cover off by gripping the attached stair treads. The unit is awkward, but not especially heavy. And having it all out of the way during the annual oil change/fuel filter replacement makes life a whole lot easier. If you have conventional (sharp-pointed) cotter pins, I strongly recommend the reusable cotter rings instead.

I also remove the steps for the engine service. I remove the rings holding the pins but do not undo the stopper knot. I twist the steps to just in front of the head doorway. A bit painful if you need to go up on deck for any reason but it does provide great access to the sea water pump for impeller replacement.

Thanks guys, helpful.

I’m now several (lazy) days into servicing my 4JH3-TE for the first time.  Steep learning curve, but knowledge is now flowing in :-)

Realising where the Yanmar service manual is misleading…. where the installation was tweaked by the fitter etc.  

Hopefully all invaluable when in trying to diagnose a fault on the high seas 

Thanks

Just remember the steps are important for entering/exiting the cabin- unless you climb out the forward hatch!
