1970 s2 0453R Reassembly

[dakazman]

  70, just start on a small object , learn the process of removing just the damaged areas and leaving the flat , unscratched areas alone. Polish and object first to see damaged areas. Be agressive, be gentle. Go over an object several times is better than giving yourself more work on a section that just needs polishing.
  Tools we talked about in the , off topics Threads. I guess I’ll have to add a few comments that I was wrong about, 4-600 grit is good enough and even 220 to see a nice polished finish once buffed with green rouge on a fabric wheel.

  Need some help. Trying to find a Renault16 ts or tx parts manual in pdf form . I need bolt lengths an size .
   Gavin and pfreen are both right, a screamer! Mecaparts has what I need or want. 82.5 mm forged piston, rings and liners.  I seems the best route to get this engine up and running ASAP. Along with some larger intake valves and it head work.
   I fabricated a plate to block off  the forward water pump on head , would it be better to install a hose bib and circle it back around to the inlet line?

Dave,
I've read somewhere that heads with the water pump at the timing end have different passages made available for the coolant.

My presumption is that the coolant flows are different.
I don't know what difference that makes or how it might be addressed if that's what's needed.

With my attention turned to another wedge since I have new chemise of stock 77mm liners and pistons. Deltacams finished two camshafts one stock and the other a modified street. Awaiting delivery , another thing they have blank cores for whatever grind you want  😃
  So I polished up another block and head while waiting. I moved forward on numerous other jobs that parts showed up to do. I had a bad month ...several items decided to quit working, chop saw, lawnmower, tools etc. Putting out those fires and the honey do list🤣. More to come.

   PS some humor for all !

Thankfully I'm married to Mrs. BDA and I don't have to worry about your last meme. I like the throat spray but do you have it in Bourbon flavor?

More shiny stuff! I can't wait for your shiny motor to make noise!

[dakazman]

Lol BDA, my wife does all the cooking and is a great chef that can make anything taste good.

   I have a plan at least to make this one make some sound,that I will enjoy driving. AC in Florida. The gearbox seal plates are still stuck , I used map gas to loosen the locktite but no joy . I need to brace the gearbox to stop it from moving around the floor. I walked away from it twice to cool off so I don’t break anything. I broke one gun off the plate all ready , learning tapping the socket is not a good no impact wrenches either . Good thing my socket doesn’t have that adapter.

  Again with things breaking my home air compressor circuit breaker burnt up and a chop saw switch.
Replaced both items and ready to make some headway on these problems.
 821 head polished and ready to go out and get some larger valves to handle the mild street cam grind. I’ll post cam cam specs when I receive the cams.
 Splitting the exhaust ports from intake again on a stock manifold for this motor so that I don’t have to dissemble the original 821 motors manifold. I wish I had a Hermès or twin DOCE 40’s manifold. Maybe I’ll find one someday ,somewhere .
  Interior back on track with a set of sewing machine needles and heavy thread to finish the door panels and seats.  Some headliner brackets for that project completed .

  Going to need another intake manifold for this build also and I had a spare on my parts shelf . It had the notorious crack and probably why I picked it up cheap. I dove right in and ran it through my chop saw and slowly dissected it. I was waiting on the trigger switch for weeks, China made 😡 and fell apart internally after being used only a few times prior.  Glad I’m a mechanic and understand things break, but lately it’s a tidal wave.
  Then I started cleaning I up 🤪👍👍
I have to order my headers, water pump and fuel pump.

It's fun to get toys, isn't it?

I think I remember that you were going with the stock mechanical fuel pump but if you decide to go electrical, I think the genuine Facet cube pumps are a great deal. Very reliable and compact.

[dakazman]

  Thanks BDA,
  I was going to switch to electric with the crossflow engine since the cam is not setup for a mechanical pump.  Since I’m putting the second modified wedge in , keeping a mechanical pump seems easier but I really want to build up the crossflow and that mod will be a logical path.
  Babysitting today but tomorrow I need to attack the gearbox issues. Rain and temperatures keeping me from that job as I need room to break out the acetylene torch.

    My cams came back from deltacams in Washington state so now to study the cam card.
They look amazing . I took the advice of a knowledgeable builder and asked for a mild street grind for a stock Renault 1565 . Cam card data below.  Please comment!
  The other cam just stock, so maybe that’s s why I only received 1 cam card but wrote deltacams to clarity.
  Progressing slowly and did manage to repair my compressor circuit breaker, chopsaw, lawnmower and a few other things. Good news I can start putting the wedge engine together 😀 polishing complete. and the door window trim, the rubber seal adhesive cams in after 2 months.  Head on it’s way back to machinist for larger intake valves.

215 duration should have it revving quite nicely!

   Finished polishing up the 821 block. A good wash down tomorrow so I can start with the assembly starting with the crankshaft and checking all tolerances.

You mean you didn't polish the counterweights on your crank?!!   

[jbcollier]

You can "knife edge" cranks.  Of dubious benefit but it looks really cool.
