Installed my crank today. Here are some pictures and a short video. Went smoothly and each journal has .0015 clearance. Crank is standard, just had it micro polished. Went with the neoprene rear seal. The side seals stick up about a 16th. [video=youtube_share;qaolP2o-F0A]http://youtu.be/qaolP2o-F0A[/video]
Thanks James, Im having a fun time with this engine. Im just taking my time and enjoying myself. Im learning a lot about Nails in the process, this forum and you all are great. Yeah, I have a thing for the Blues. Got the XM radio so no commercials. :laugh:
Nice pics Rob. I photo documented the plastigage readings on mine as well but your pics came out better! Probably didn't help my digital camera is 10 years old. Is the rear bearing cap sticking up above the oil pan surface plane or is that an optical illusion?
It was an illuision, after I saw the video I had to run back out and look at the cap! :laugh: I didnt like the side seals sticking up as far as they ended up tho, so I ended up installing a new rear main seal and used anaerobic sealer instead of the black rtv. So now I can sleep easier. ---------- Post added at 01:33 PM ---------- Previous post was at 01:30 PM ---------- Todd, Thanks for the compliments on my shop, yeah its open air, makes it nice on hot days, and when it rains I just take the day off! :laugh: Well Sometimes I can take the day off.....
Been a while since I chked in...... Busy with some other issues and what not. Got the bottom end and heads on, painted the block and heads today (factory green) and should be able to get this puppy bolted together and drop it in hopefully next week if things go the way I want. (yeah right! :laugh Oh yeah, if anyone wants a great deal on a new TA 20 Cam I have one, PM me. I had got it and decided to go with a different cam at the last minute. I did degree it with a stock timing set and it was within a degree. Here are a couple pic's
thanks gsgtx, I went with this after much mulling it around. http://schneidercams.com/262-70Hnailheadhydraulic.aspx I sent in my original and they checked it's specs, (I have the info at my shop) and talked to them, I wanted a good idle as I plan on using the AC in the summer, so I didnt want to go to wild. The 262-70 matched up real close to the original.
Did the final engine assembly and stuck the 425 back in the Rivi today. Went smooth! :Smarty:. Now I just have to do the final hook up and start it up. I went with Felpro Head gaskets (permatorque) and I plan on torquing them after running it, do you guys think its a good idea or a waste of time? Anyway, here are some pics: you all have been a great help and resource for me on this one!
Yep,,,, tork them..... that used to be part of new car make ready.... warm the engine up completely then tork the head /intake bolts,,, and it would be a good idea to tork the exhaust manifold bolts too,,, or at least retighten them from the center out to each end.....
I was thinking I would run it and break in the cam, then shut it down and tork the heads, is that enough running time or should I run it longer?
Rob, that will work....back in the day, the factory said to just let the engine idle untill it got fully warmed up and then retork...so what you want to do should work just fine....:Brow:
After the run-in/break-in I usually let it cool overnight, then re-torque. Heads, intake & exhaust from center out. Tom T.
TY Both Tom and Doc. You guys are alright! It will be interesting to see if or how much the torque changes after running it. I like this stuff. It looks like I can get in and do it without pulling the rocker shafts out, Ill just have to take that front power steering pump bracket off to get on the head bolt in that location. but thats no big deal. time well spent.
OK, did a fast little 20 second run on the 425, This is its first crank up. Will do the cam break in and retork tomorrow.
Sweet video Rob,it sounded great,but what was that white mist being blown by the fan when you blipped the throttle towards the end of the video? I hope that wasn't fuel.
Nope not fuel, I had just hosed off the radiator before I installed it today and what you are seeing is just clean water vapor that was left in the core fins. (that fan really hooks up).
Sorry Rob, but that's the worst thing in the world to do to a new Engine, starting with NO water, even for 30 seconds. Doubt any harm was done, but will need to get up to operating temp. & an overnight cool-down before retorquing.
