Engine Refresh

[barry123]

Just finished an engine refresh, Standard bore, bought +020 thou. rings, filed the end gap to .010 thou. spacing. New std. rod bearings plasti-gauged and are within .001 thou. of the .002-.003 allowed. Reseated the valves the old fashioned way. New head gasket sprayed with copper kote. New grade 9 head bolts treated with thread sealant and torqued to 45 pounds. Rebuilt carburetor. New plugs and wires. Runs lovely now and no more blue smoke.

Glad to hear your refresh job was a success!

Thank you, I tried to add some pics but it keeps telling me files to large.
I will have to try to take some with less megabytes.

Barry, what did your bores measure to make you go with oversized rings filed down? Just curios since I’m a machinist.

[barry123]

I never measured the bores precisely, I new it was a std. bore and the rings
that came out of it had a very large end gap so I new they would not work
so I opted for .020 over and file. I measured the end gap at the bottom of the bore.
This is the first one I have ever done so I was hoping for a good result and so far
all is good. I did a lot of reading beforehand on this forum to help me along and
I do thank everyone for the information that you post.

If you think about it, the bores wear like a flower vase.
They are original size at the bottom because the rings never reach down that far and there is essentially no wear points.
They are wider in the middle due to the friction of the rings and the wear caused by the combustion.
At the top, the cylinders are narrower than the middle, but not as small as original because the rings don't touch there, but the combustion wears at it a little.
Your rings will have a small gap at the bottom and a wider gap in the middle of the stroke.
If you had the cylinders bored, they would be straight walled again (a perfect cylinder shape). Hopefully, your bores have not worn to be egg shaped. Measuring is certainly best!

Here's a couple threads and/or places to read about posting pictures:

• How to Upload Pictures to a Post
• Forum Picture Posting And Other Interesting Things You Can Do
• Using the Forum

There are also ways to take your existing pics and downsize them. I open them up in Paint, select "Resize" (second grouping from the left in the pull-down menu), then select "Pixels" and make the horizontal dimension about 1000 or 1200. The "Maintain aspect ratio" is usually on, so whatever size I make the horizontal, the vertical size automatically changes to keep the picture in the correct ratio. Re-save the image with another name like, "001smaller.jpg" and you're set. Upload as an attachment to your post in FarmallCub.com and we all can enjoy!

Thanks for the tips on adding pictures, I will try at some point, computers are not my best friends.

Need to do this myself as the poor old 53 has started blowing smoked an has a good amount of blow by and I use it pretty hard with a belly brush mower . Just wondering if there is a good machine shop in eastern CT, RI or eastern MA.

Most tractor people around here, use Simplex, in Providence.

Any idea as to s ballpark cost?

[staninlowerAL]

Depends on how much of the work you can/want to do yourself. CS about $200, bore $100/hole, deck head $100, boil out and cleanup all parts $2-300, replace valves and seats $250, you can easily spend $700-$100 for machine shop work. Add on disassembly/reassembly labor and new parts and gaskets and you're probably looking at a total rebuild cost of $1600-$2400 in my area of the deep south.
