Has anybody tried to use a YM195 injector pump on a YM155 ? I was quoted $1100.00 to rebuild my pump
because of parts costs. They look identical, but who knows, and they're only about $400.00 new.

Any ideas ?

You can get the pump rebuilt for under $300.

Thank You for the reply,
I did contact Mike and he told me which pump should work for my tractor. Now I'm just waiting for it to arrive.

Hi Dan. please let me know how this went for you. I'm looking to replace the IP on a 276 (3 cylinder yanmar). Did you have to do anything special when pulling off the pump or putting the new one back on? Injection pumps are a whole new ballgame for me.

On my tractor its dirt simple actually. Remove the fuel line, injector lines, and the 4 bolts in the top and pop it out. Be careful not to damage the shim if you have to "persuade" it to break loose. When you put it back in, be sure the finger on the rack gear goes into the slot in the governor.
If you replace the pump, you should probably check the clearance between the pump rollers and the cam lobes that drive them.

My tractor looks to be the same 4 bolts on the top. I think all three pistons are locked up. Getting zero fuel to the injectors. But the injector is getting plenty of fuel. Not sure what that "finger on the rack" is, but I'll watch for it.

You didn't run Into any problems with reinstall and timing issues?

Thanks for the advice on the shim and checking the clearances. Will do.

I haven't taken the time to re-install mine yet, I've been trying to get the house ready to paint.
Also, it seems one of my tubes is plugged. I cut short pieces of fuel line and pushed one on each end of the line to use as a reservoir. I tied it up on a porch railing and poured (at different times and hanging in opposite directions) acetone or PB blaster in the tube. I don't know where it goes but it didn't come out the other end.
Anybody know a cure for that?
OH, this won't affect timing, so its not a worry.

What tubes are we talking about?

What tubes are we talking about?

The steel tubes from the injector pump to the fuel injectors.

That seems odd the solvent doesn't come out the other end...

I'll have to check mine when I get them off. Have you tried to put some air through them?

Yes, it is odd that you can't blow air thru it. I've tried diesel, pb blaster, WD40, marvel mystery oil, and acetone without success. I usually let it set 2 or 3 days each time i put something different.

If you have a 1/8th or 3mm firm wires, use it like a plumbers snake carefully to take the blockage out of the metal fuel line.

Work the snake wire in and out removing the clog in small attempts until the last one gets thru. Don't jam it all thru at once.

I know snakes. The problem is that each end has a fitting brazed (I think) to it that has about .015/.020 dia. hole in the center and I don't have any small stiff wire.
