You're welcome Crabbie. My hope is that with 3 802s sitting around, I'll be able to swap electrical stuff around if needed, to get them fully operational, at least 2 of the 3. Funny you should mention 802s being parted out from the Crane auction. I picked up some 802 parts from one of those...

Thanks Rusty! So got the gear back on the crank. Had to heat it quite a bit to get it hot enough (TM calls for "straw yellow" color, but I wasn't able to get it quite that hot). Anyway, it slipped on pretty easily with just a couple of light taps with a rubber mallet and a large socket. Next...

Next up was gapping the rings. Here's the neat little tool I picked up for the job. The regular wheel seems to do a great job. I did a final "deburr" using a fine file. http://www.cstone.net/~dk/MEP802-9-1-14-11.JPG TM states ring gap should be between 0.01" and 0.02". I made all of them...

Made some good progress today. After a final touch up with the fine 400 grit hone stones, I pressure washed the block prior to final assembly. http://www.cstone.net/~dk/MEP802-9-1-14-01.JPG Next up was cleaning the crank. http://www.cstone.net/~dk/MEP802-9-1-14-02.JPG Center crank bearing...

Ok, so you're saying I should just file down these oversize rings to fit into my standard bores? Something like this right? http://www.speedwaymotors.com/PRECISION-PISTON-RING-FILER,2915.html Peter

I think one of my problems was that I was using a variable speed drill that did not have a "lock" feature to keep the speed constant. So unless I held my finger in the exact same position, which was nearly impossible, the speed would change up or down quite a bit. So I found a drill at the big...

Thanks for the additional clarity. I think some of my photos are misleading due to angle and lighting. Once I get a chance, I'll take some better pics. Didn't get a chance to work any more on the 2009 over the weekend (youngest daughter's 2 year birthday), but hopefully will soon. The rings...

Appreciate the feedback. I just watched some YouTube videos and I think I saw more videos of how NOT to hone. Some of those guys are running the drill at full speed and barely moving the drill up and down. Did see a few good ones. One thing I wasn't doing was to pull out the stones while the...

So I honed it some more this morning and then dropped it off at the machine shop for some hot tank action. Picked it up a few hours later. Looks a lot better now! http://www.cstone.net/~dk/MEP802-8-14-01.JPG http://www.cstone.net/~dk/MEP802-8-14-02.JPG...

Redid the bores using the 400 grit. Here's what they look like now: http://www.cstone.net/~dk/MEP802-8-13-01.JPG http://www.cstone.net/~dk/MEP802-8-13-02.JPG I've had the cylinders soaking in carb cleaner and this is where they are at. The #1 (on left) looks a lot better than #2...

Thank's for the tip. I just ordered an 8 oz bottle of that stuff.

Thanks. Yeah, the NAPA honing tool came with medium 240 grit stones, it does look a little rough but really helped knock the deposits off. I stopped by and picked up the 400 grit fine stones from NAPA this morning. I'll go over it again with the new stones tonight, speeding up the drill some...

Got the generator bearings ordered. Turns out the local Onan guy was able to get them dropped shipped for $8 a pop with very little shipping. So I went ahead and got 3 of them. Was also finally able to find a reasonable price on standard ring sets at $40 per bore. This was for the Onan...

That's exactly what I did CDR. :) Quote from a few posts above: [/COLOR]

It would measure a lot less Rusty since the skirt doesn't extend out to the full bore diameter 90 degrees from the first measurement. I would have to measure the top of the piston if I want to take 2 measurements. This picture shows what I'm talking about...

Thanks Rusty :) So I calibrated my 4" micrometer against a 3" calibration stick and measured from there. So adding 3" to the below reading, I get 3.38555" http://www.cstone.net/~dk/MEP802-8-11-01.jpg Normal size piston in standard units is 3.3815 - 3.3819, so mine are over sized by 0.00365...

Name is Peter rusty. :) Part number on the current pistons is 751-42670/5 The diameter across the bottom of the skirt faces is 85.96mm using my cheap digital calibers. Spec states the initial dimension as 85.891 - 85.901mm. I'll re-measure with my new digital micrometer once I get it...

Got the governor, cam and crank out. Here's the governor and timing rack pulled: http://www.cstone.net/~dk/MEP802-8-9-01.JPG Pulling out the center bearing oil tube using intake manifold bolt: http://www.cstone.net/~dk/MEP802-8-9-02.JPG And here's the guts from the engine...

So on the rings, there appears to be 2 different part numbers: Piston ring set - standard ............................................750-11401 Up to 4100323LPW2 Piston ring set - standard ........................................... 750-13120 From 4100324LPW2 Since this particular unit is from...

You guys convinced me. I'll tear the block the rest of the way down. Really weird how the crank pulls out the side since there is no oil pan to drop like on most engines (at least the car engines I've worked on). Will be an interesting exercise I'm sure. I'm glad I got the TM and this forum...
