Dumbo The Flying Elephant

[Larry Hill]

Has anyone noticed how the tolerance of parts seems to be expanded. I bought some stuff that was advertised to be .060" thick out of 32 parts no more than four were .060" thick. Thickness range was .064" - .056". Many of them would vary .003" across a face of 1.311". All was not lost with the unintended variations in thickness it allowed a closer set up than + or - .015'' shim choice.

............and so it goes

After cleanup, put up, straighten up it will be rod and bearings day. I’m happy with how close I was able get the heads to my target. I just hope I have the correct target.

[Larry Hill]

Checking for rod bolt stretch. .602 in the relaxed position. After .0055'' stretch to 6075''. After all the bolts I will check big end of rod. I think size is min. to max ID is only .0005.

[Larry Hill]

Rods all checked good. Installed bearings and checked crank pin size and I had the desired vertical clearance inside the bearings. I have new oil rings and second ring to check in the bores tomorrow. Tonight I’m doing a little paperwork so I don’t lose my way or remind me of what not to do next time.

[Larry Hill]

I don’t know about you but I have a difficult time accurately measuring end gap of the oil rails. I always seem to upset the ring in the bore with my feeler gage making the measurement questionable. The solution for me was using gage pins to measure end gap, it works like a charm.

[Larry Hill]

Finely got the clearance almost like I wanted, you might have noticed I didn't say correct. Standard bearings were a little tight and used plus .001 were a little big. New plus .001 bearings are not to be found. Semi solution, a half and half mix of new and old bearings. With my new ball mic I was able to check shell thickness of old and new parts.

Now I will clean my was tank and install fresh solvent so not contaminate the engine with foreign materials. After cleaning the block I have to reinstall the cam bearings, passage plugs, and dowels.

For lunch we went to the 142nd Fancy Farm picnic where you have a choice of ten tons of meat. BarBQ pork, beef, mutton,and chicken plus all of the home cooked green beans, creamed corn, slaw, home grown tomatoes, Lima beans, dill pickle spears, home made deserts, with fresh iced teas and lemonades. It’s all you can eat for $15.00 a person, for me it’s a great deal. It’s a bit of America that most people don’t know about.
I really need to take a nap but I have to get back at it!

[Larry Hill]

I’m ashamed of myself self, I took a nap instead of working. So I’m up and
at it this morning.

Slacker!

[Larry Hill]

I got the solvent changed out in my tank. Installed cam bearings test fit cam and it turned freely. Installed plugs in oil galleys and quit at supper time. For me I’m putting parts together maybe dyno early next week. I’m more than ready to here some 8000 pulls.
