Need Mechanic

[ray_reilly]

Well I broke it. Had a crack in my water pump housing. (YM2000) ordered new one Broke bolt off in head installing new one. Try easy out, broke it also got most of it out ruined threads. Need Help Any one know of mechanic in the Sanford, Eustis, Deland area of Central Florida. In my defense the new housing is .25 inch thinner then old one.

Hope to hear from someone soon

is it possible to use this Heli-Coil, Helicoil, Helicoil Insert, Helicoil Tap, Helicoil Inserts, Helicoil Gauge, Helicoil Kit, Helicoils, Emhart Helicoil, Bollhoff Helicoil, Helicoil Plus, Armacoil, Armstrong Helicoil product to make the repair ?

Touchy situation here. I have had success in going just a tiney bit larger and maybe go to a inch size bolt the size larger than the metric you are dealing with. Not saying this is your answer but something you might look at.

I believe the products would work. But I think I'm at my limit would like to hand off so I don't do something I can't recover from.

The bottomed-out, jammed bolt plus the hi-tensile steel ezout that snapped are both stuck in the head with nothing protruding to get a grip on?

Pull the head and take to an automotive machine shop if you want it done right.

How difficult is pulling the head. No garage working in yard. I have replaced water pumps and starters done oil changes and alike.

Pulling the head on that little two cylinder engine is real simple, no more complicated than a starter or water pump except several times longer to do.

The only parts that are critical are cleanliness, head bolt torque, and adjusting the valves and the compression release. And don't drop the pushrods down into the pan.
All the rest of it is 'well this is in the way so I obviously need to take it off' like the air cleaner, fuel lines, etc.

You must already have the fan shroud off and that is maybe 10% of the project right there.

If you have to work outdoors, you might work over a tarp to catch anything that falls. You can still drive the tractor a few feet without coolant in it, if you need to move to a carport or something.

Given the location of that broken bolt I think it would be impossible (for a weekend mechanic) to accurately center punch a starting point for your drill and then drill in perfectly straight. - into that tempered ezout that probably didn't snap off perfectly flat.

1st try uploading a photo. I pulled the head and will be sending to a machine shop. But I had one injector that was loose. If you look at the valves the rusty one was the loose one. Should I be worried about this if so what would the fix be. I have other photos am going to try to piece them together as a photo repair. And thanks for the recommendation on putting the tarp under the tractor it came in handy more then once!!

If you don't have a torque wrench it would be wise to get one to torque the head bolts. You don't need to break another bolt. All bolts have a tightening torque value.

I agree, a torque wrench is essential for this.

Looking at that head I wonder if the rust is coolant that got past a leaky head gasket. It also looks like compression went the other way, smoking up the gasket sealing surface near the coolant passage. Exhaust in the coolant will cause overheating. Was overheating what caused you to replace the water pump?

If water got in the cylinder before cranking it over in the morning, that might explain the loose injector - water is incompressible so the cylinder pressure had to go somewhere, if it didn't crack the piston or bend a rod. Maybe the injector was the 'safety valve' this time.

I'm just speculating. The shop that repairs the head will be able to tell more when they look at it.
