Journal Measurements

[Mosebrosdsm]

Just got my crank back from the machine shop after a polish and ball removal. Mic’ed all the journals this is what I got. Stock 6 bolt crank

Need some help/suggestions if i should still use this crank. The specs are at the very lowest amount according to the service limits

1. Front correlates with oil cover side
2. Rear correlates with flywheel side

Mains: ordered from flywheel to oil cover

Horizontal 1.) 2.2433 2.) 2.2434
Vertical 1.) 2.2433 2.) 2.2434

Horizontal 1.) 2.2434 2.) 2.2434
Vertical 1.) 2.2434 2.) 2.2434

Horizontal 1.) 2.2433 2.) 2.2433
Vertical 1.) 2.2434 2.) 2.2434

Horizontal 1.) 2.2433 2.) 2.2433
Vertical 1.) 2.2433 2.) 2.2434

Horizontal 1.) 2.2434 2.) 2.2434
Vertical 1.) 2.2433 2.) 2.2433

Rods: from flywheel to oil cover

Horizontal 1.) 1.7706 2.) 1.7707
Vertical 1.) 1.7707 2.) 1.7706

Horizontal 1.) 1.7707 2.) 1.7707
Vertical 1.) 1.7706 2.) 1.7706

Horizontal 1.) 1.7707 2.) 1.7706
Vertical 1.) 1.7706 2.) 1.7706

Horizontal 1.) 1.7707 2.) 1.7706
Vertical 1.) 1.7706 2.) 1.7706

I hope you guys can understand this I tried my best to keep it thorough yet readable.

I read the service specs for the rod journals are supposed to be 1.7710-1.7717

Please help and correct me if I’m wrong. Where should I go from here.

Put some bearings in your rods and torque the caps. Set a bore gauge off of the mic for each journal then put it in the rod big end to check vertical oil clearance.

So I did some triple and quadruple checking with my measurements on my rod journals. They varied from 1.7703 to 1.7707. I torqued my 1g rods with standard ACL aluglide rod bearings in them down to 37 ft pounds. I used the tools that were at my disposal. I used my telescoping t-bore gauges to check for bore size of my rods. If you ask me they are a hit and miss when trying to get very accurate measurements but they work ok for the amount I use them. I came up with measurements that varied from 1.7731 to 1.7725. I did the math and my oil clearances varied from .0021 to .0027. If any of these sound off or wrong please lead me in the right direction. I was expecting to see measurements in the .003+ range s i guess i am somewhat pleased with these.
