I'm at the same spot you are. I just Dry film lubed my bearings and skirts. I powercoated the tops and combustion chambers as well. Still need to find some good sc cams to lube and finish things up. Excited like you to finish.

I have a good set of SC cams if you're interested.

what is the coating on the pistons? koool. and the bearing treatments?

quattrorunner 11-11-2010 08:15 PM

The coating is dry film lubricant on bearings and skirts. It's a process and coating that adds extra protection from wear. The powercoat is a thermal barrier/dispersant. It helps to deter hotspots. Check out techline coatings for info and ordering. You would need an oven if you want to do it yourself.

Update --

Dropped off my case, crankshaft, rods, new je pistons.. to Mike Callas at Rennsport for all the cleaning and machine work.

Have all the new parts ill need to reassemble... So hope to get back my freshly cleaned and machined pieces in a few weeks.

crazy rod u found there.... def going to keep an eye on this build

brads911sc 11-29-2010 07:04 AM

Update--

Machine work done. Everything cleaned, inspected, polished, and within standard specs. Pick up my cleaned and machined parts on Wednesday.

Issue...
 
So Rennsport didnt mention this damage.. and maybe its not a big deal. Not sure how it could have happened... Makes me alittle nervous...

Repair? Leave it? JB Weld?

I posted the same pic too.

Wow. Thanks guys. I had visions of oil gushing out after I had it back together. Enjoyed your thread MCA. Well done.

Im in the cleaning stage now while I wait for my main/rod/intermediate bearings to come back from WPC (Charles Navarro recommended / WPC - Metal Surface Treatment / Micro Shot Peening). Its different from the standard bearing coatings as it doesnt impact clearances.

Thanks! It was a wild ride. Hope to do it again someday if I can afford it :eek:

Update - Intermediate Shaft
 
Progress --

I used JB Weld on all the areas of the case in Wayne's book. So that is complete.

I opened up the oil pump. No fragments. No excessive play. Smooth as butter. So I just bolted it back together and will reuse that.

I decided to clean and inspect my Intermediate Shaft. I wanted to change the Chain Sprockets at the very least. I am glad I looked at this today... More bad news... There is clear pitting /gouges in the area that rides on the bearing towards the oil pump. Someone might be able to polish it out... Not sure. I ordered another one from our host. Here are some pics..

Update--

Well I made a rookie mistake. Torqued my first rod 180 degrees instead of 90. So Im waiting on a new set of rod bolts/nuts.

I received the new Intermediate Shaft this week.

I received my Main, Rod and Intermediate bearings back from WPC this week.

Pelican is sending me one of the RSR o-rings for the rocker shafts, the packet only contained 23 instead of 24...

I had Rennsport (M Callas) install my rings, measure them and make sure they were correct. I am sure I could have done it, but there are things I think the pros are better at when only given one chance to get it right. Measuring and trimming rings for a perfect fit is one of them... Only took them an hour... Would have taken me ALOT longer...

So getting close to assembly. Ill post some pics as I assemble...

Holy strength! I recall having a hard time getting to 90 degrees!

brads911sc 12-18-2010 10:07 AM

LOL. Well i used a breaker bar of course. 180 degrees was pretty tight. The real 90 was much more reasonable....

I didn't even think about pulling out my breaker bar. Would have been MUCH easier. I just stuck with the torque wrench. I'll remember that for next time.

brads911sc 12-18-2010 06:18 PM

Here is a pic with the treated bearings installed.

Make sure to inspect the back side of the bearings for over-spray. You will need to clean any off with 600 grit wet dry sand paper. If you don't the material left on the back side will effect the clearances. The sanding of the back side will also add a degree of bite by the bearing to the case when assembled and bolted.

brads911sc 12-19-2010 06:51 AM

Thanks Lindy.

The WPC process is a micro-shot peen using solid lubricants such as Tin (Sn) and Molybdenum Disulfide (MoS2) and doesnt consist of any material added to the bearing surface. (well according to the sales pitch)... so I think I should be fine there but ill check it. This is an interesting process that Charles Navarro recommended.

WPC - Metal Surface Treatment / Micro Shot Peening
