aftermarket kits

I was taking my rods out to have them harden and found more problems rings stuck and crack on piston. Was wondering if the after market rebuild kits will hold up to pulling.

figured i would send pistons and rings and rods are to get harden.

I didn't expect all these problems. I was wondering if the rings were stuck from sitting tractor had sat for 15 to 18 years only has 1500 original hours

If your rings were stuck prior to pulling it you would think it would start hard and take lots of ether to get it going. Did it? With that said, too much ether will crack the pistons between the ring lands. Is that where it's broke?

We previously talked about injection pump timing:

1 - Are you sure your pump is marked / timed correctly? Who did your pump?

2 - What is the spray angle on your injectors in relation to the bottom of the cylinder head? If it is a really flat pattern (like 10 degrees or less) it may be causing problems. To the pistons a very flat spray angle may look like too much timing.

3 - Be sure the outer ring of the front crank pulley (with the timing marks) has not slipped on the rubber isolator. That doesn't happen very often, but it can happen.

I had taking pump and injectors to highly recommended guy and he sent pump out and when I got it back note had said timing removed from pump and set at 35 degrees.

After all that when had to move it a couple of times it took some fluid to get it started at home unless that's when the damage was done.

Well you need to overhaul the engine no matter what. Don't spend good money on new pistons. Find some nicely used pistons, clean them up, check them over well and if they are in good shape use them with a new set of rings. Same goes for the sleeves. Good used will work just fine.

I don't know what "removed the timing from the pump" means unless the advance was locked.

Is this a 180, 185, or 190?

Why don't you email me at opsheads@hotmail.com. I have a few more questions and inexpensive recommendations that may help you while you have things apart.

OK a model 200. I guess you mentioned that before. Send me an email.

If you have any video, post it. Let's see what you've got.

My sleeves except for one still have cross hatches thought about using them but pistons cost as much as kit

Yes with your sleeves only having 1500 hrs. on them they should be perfect, Hone em and run em.

Do what you want on the pistons, but you can probably buy good used 15:1 pistons for $10.00 each. Save the money and spend it on things that actually make it go faster. If you want to buy new sleeves and pistons, you may as well by my 341 C.I. drop in kit and have 40 more cubic inches for the same money as a new 301 kit.

No matter what you do you need to have your connecting rods heat treated. Be careful where you send them to have that done. It's much more of a scientific process than just heating them up until they are orange and dropping them in a bucket of oil.

I have never cryo'd anything so I have no experience with it. I have heard it's a good process which makes things stronger. I have experience with properly heat treated rods and know they work well.
