Nice job Niz! Did your big end bearing clean up OK after the "plasma spray" piston blow through??Sometimes it really lodges in the needle bearings badly..

I'm pretty happy with how it's turning out. Honestly John- IDK yet. I haven't even really inspected the big end but I wasn't even going to bother chancing it with the case bearings- just replace them- the "plasma spray" was quite fine and I"ll admit that It'll be in the back of my mind even if I do think I got the big end cleaned up good enough

So I used my bearing extractor tool and got the bearings off the crank shaft. They were in pretty bad shape- filled with aluminum and very gritty. The big end bearing is abosultely smooth and spins perfectly without even the slightest hitch or feeling of a grain of grit in there. Seems like it survived without any contamination... Yeeha!

Looks great all but that thread hole... I hope it holds after all that nice trenching!?

Looks great all but that thread hole... I hope it holds after all that nice trenching!? I know right? I was concentrating on making the best path all the while not realizing I was leaving so little meat for that stud. I'm thinking of dropping a ball of epoxy in that hole and trying to build it up a little more. I think of the amount of force pulling on the studs and such little material holding it in there... will update with results...

Hi fellas, I'm wondering if I can ask for some help here? I whipped up this little jig to test the runout of my crankshaft; Not pretty but functional! The youtube video I watched said the runout max should be .002- two thousandths. I think I am within tolerance at .001 (one thousandths) but I don't know if I am reading this gauge correctly. I think I am but I'd like to know what Y'all think! Here's a quick video I made and thanks so much in advance. I really do appreciate all the knowledge I gain here!

Yes, You are right Niz!Check both sides too.The best way to check runout is with 2 indicators,that way twist can be easily detected..If both sides are like the vid,it'll run well!!Treat it careful on installation as they are very easy to 'tweak'..

Looks good! I like to check em at the end of both shafts for extra assurance. You wont get a 100% true reading at the thread end or vari shaft but will still see if its out or bent. Be careful knocking the crank around if/when you ever do.. Like 190mech mentioned 2 indicators is best. He has done more truin than I but he might agree with me that it can be kinda frustration if you get one spun a bit on the pin and pinched at the wheels It really just boils down to patience a soft and hard hammer, and a hard chisel.

Awesome thanks fellas! I have installed this crank already once before- good to know I didn't get it all out of whack!

Ok so the next tool I need to assemble my engine is a leak down tester! I built one tonight and as you can see it looks nothing like the "typical" leak down tester does... I didn't necessarily set out to reinvent the wheel but I did want to finish it tonight without waiting on ordered specialty parts. I built it from materials available from Walmart and Home Depot. It's construction is pretty much self explanatory- some PVC parts, a bicycle pump to add the air, a tire valve, a threaded nipple to clamp the valve to, and a low pressure gauge (this was probably the hardest part to find- I checked the usual places like HF, HD, and Walmart but all the gauges start at like 10 psi... I found this low psi beauty at Auto Zone!) I capped the end and pressure tested the leak tester itself. Holds 15 psi for over 10 minutes no problem. Time to build an engine! EDIT: I also found that this thing doubles as a pretty powerful little gun! Just slowly loosen the clamp that holds the blue 'cap' in and BOOM! a surprisingly powerful projectile! lol Kids don't try this at home.

Nice job coming up with something quick. If you ever need to change crank seals just hook the air compressor to it and blow them out. **Totally a joke! No one try that! You'll blow the welds on your intake! **

I like the tester and ingenuity!
