Yanmar 2ym15 Injectors Install help

Ive removed the injectors and had them serviced by a diesel specialist, that part was easy.
I've also purchased new copper washers, and the nozzle protector etc. from Yanmar, that was also easy apart from the cost.

The issue I've got is removing the old nozzle protectors.
I got one out today but it was an unholy exercise which I hope never to repeat. I also fear a small piece of copper washer dropped through (about 2mm square)!! Ill vacuum tomorrow with a small pipe into cylinder head and cross fingers.

Part of me thinks just leave the other one in and reassemble but as I've come this far I wouldn't mind getting the other one out as long as it doesn't become another debacle.

Does any one have a special technique or know of a special tool to get these things out.

Re: Yanmar 2ym15 Injectors Install help

I think that at this point I would pull the cylinder head. You really do need to get into the cylinder with the copper fragment, and being able to access the stuck injector protector from the other side would let you use a drill bit as a wrench in the hole in the protector. From the cylinder side, loose is clockwise, and a right hand bit could grab the sides of the hole.
Never let anything mechanical know that you are in a hurry.
