 Cleaned and inspected the entire wiring harness, re-taped everything with high temp 3M automotive electrical tape. Installed the harness and added extra hold downs and wire ties where possible, just trying to tidy up a mess of wires. Added one of  Glens' fuse holder covers. Absolute worst part about this whole build...... Also put on a piece of tin.

All this accomplished in only 5 pages!   

Outstanding work.

Super nice job Brian, Would love to see that in person at the BS in June 2021. That would give any 420-LSE a run for it's money IMO .

  Was able to save and re-install the decal that is usually found on the hydraulic cylinders. Actually remembered  it BEFORE I put the covers on .

 Finished installing the last of the sheetmetal and my spiffy new LED tailights. Also installed a really sweet reproduction parking brake lever......

What brand on the LED taillights? Optronics?

  Have the engine torn down ( as far as it's gonna get ) compression was great, cylinders still have the crosshatch in them , so it's just getting mostly a good cleaning, detailing, fresh gaskets, carb rebuild, etc. Tins are getting blasted and I did both heads while I was at it.

Went thru the carb and gave it and the intake manifold a little love.

Looking darn good! Leaking intake manifolds are a known issue. Several threads here about resealing them. If you don't want to split the intake apart, at minimum it's a good idea to replace the rivets with nuts and bolts, one at a time. Loctite them. Then scrape off the visible rtv and go along the seam with new high temp rtv. Eliminates 99% of any future vacuum leaks. Splitting and resealing gets you to 100%.  Can't wait to see the final pics!!!

Ultrasonic tank?  Looks almost new!

See that cut on the side of the intake just below the vacuum connection?  Grind away a bit of the heat shield that cuts it there.  Also look for cuts elsewhere.

I had that same notch where my front exhaust heat shield was rubbing the intake manifold...never would have noticed it had it not been for you guys!

It's good now since I trimmed a little off the heat shield.

I opted to not split my intake into 2 halves...but I'm sure I got a good seal with the RTV that I used to seal the seam after a good cleaning...the RTV cured almost as hard as metal, and was I was not able to dig my fingernail into it.

Beautiful work!!!!!

@Horse Newbie, is RTV a silicone caulk? Hope I am not raining on your parade, but are you sure that stuff is ok for exposure to gasoline and for high heat? Only a very few Permatex products are gasoline rated.

Motoseal is what I use for all intakes kinda runny one of the only gasket maker made for fuel exposure https://www.permatex.com/products/gasketing/gasket-makers/permatex-motoseal-1-ultimate-gasket-maker-grey/?locale=en_us

Don't look at it at all like you are raining on my parade...you are just asking a question, trying to be helpful.

To be honest, I may have described what I used incorrectly. I'll have to try to find the package( if it hasn't been tossed) and see if it was/is suitable for the application in which I used it.

I do believe whatever I used, I read the package, and it was compatible with exposure to gasoline.

What does it look like to you if you can tell by the pic I shared ?

@Handy Don , @Shed  That's it ! That's what I used ! 

Thanks...now since I kinda took this thread off topic...man that 520H restore is unbelievable !

 

Outstanding talent and attention to detail ! @76c12091520h

Glad to hear that it was "the good stuff". That job is not one to look forward to repeating. Keep up the good work on the 520--they are very impressive machines.
