Well figured since everyone loves pics, I mine as well post the progress of my engine tear down in the 1050.

Today I got most of it appart.

Looks like she will need some new valves and guides. A new set of rings. there was a little bit of wear on the connecting rod, so I'll put on the new one that I bought a while back on ebay.

Hey! Where the pics go to? Clicked on one & then they disappeared!

[Bolens 1000]

They should be back now
I put them in order....

[olcowhand]

Pics came back! :) That rod would dress down nice, but being you have a new one, sure put it in there. Don't toss the old rod though...as I doubt you would. We're at the same stages with our Wisconsin 10's.

[Bolens 1000]

Yeah, I'm going to save the rod. I'll save it for another engine project because like you said it can be mended.

[Bolens 1000]

Next thing I will do is take the valves out and inspect the guides. the clearance gap on both the valves is over what it is supposed to be.

[olcowhand]

My valves seem to be in good shape. Can't feel a wear edge on the stems. With the guide I took out of the S7D, I think I'll be fine as it is lots snugger than with the original guide. My exhaust side seems fine as-is.

Got the rest of the engine dismantled today. There was a good bit of play in each of the guides, so they will have to be replaced. I also found out that the engine must have been rebuilt at some point in its lifetime. The piston had +.030 stamped on it, so I'll have to get a set of oversize rings in it. I took a second look at the connecting rod and decided to salvage the old one like Daniel said. I did not take any pics today, but I'll have some tomorrow. This weekend I'm heading over to to the wisconsin dealer to order the stuff I need.

I'm just barely ahead of you now. My block is 3/4 sandblasted, so that is my only lead. You'll end up passing me like I'm sitting still. Too much work on the farm to leave me with any time or energy in the evenings to work on it.

[Bolens 1000]

You may still pass me yet LOL. I have to still order the parts and clean up the engine.
Last time It took 2 weeks to get all the parts in when I ordered some...

[Bolens 1000]

Got the engine block cleaned up a bit today.
All I got to do now is order the parts....

looks good! let me ask you a question is a TRA-12D in the same family as a TR-10D? if not what is the difference besides obviously one is a 12 and one is a 10?

[Bill56]

You're making good progress Brian. You'll have a "like new" engine running in no time!

I have the manual for both in front of me. Both are 3 1/8" bore, the TRA has a stroke 1/4" longer...2 7/8" vs 2 5/8" strokes. The TRA is 22.05ci and the TR is 20.2ci...both rated 10hp though. For comparison, the TRA-12D is 3 1/2" bore with 2 7/8" stroke at 27.66ci.

Went to the wisconsin place today and ordered a set of valve guides, Exaust seat insert, both the intake and exaust valves, and a set of .030 over chrome rings.

They will call back sometime this up comming week and let me know if they can get all the parts. Some of the parts were questionable for availability. If I cant get some of the parts I guess I'll have to get them from somewhere online. Most likely from sam's.
