Yes, not turning is bad but what I said is not growing old is bad!

Keep up the great work Dave! Your making real progress, plus learning all about Renault engines

Pulling parts out of bags today and sorting miscellaneous engine bolts . While cleaning and getting into the chain tensioner inner oil paths and construction I noticed the difference the wedge and crossflow differ. The crossflow doesn’t have the outer cavity bolt and retainer, once engaged it is set and needs to be unbolted and reset to be installed again. It also slightly sticks out of the cavity when fully installed whereas the wedge type sits behind cavity tab until set .
   The wedge engine has the bolt and retainer the covers are the Allen wrench reset . The main reason for posting this is that I found a significant amount of metal chips in one of the assemblies, 4 in total that I collected, in the last chance filter in the assembly spring. The donor engine had two blown piston and I will definitely clean out that engines oil galleries. If anyone is rebuilding their engine Or replacing the chain, disassemble the tensioner completely and clean that filter.

There are many different permutations of the timing chain tensioner.  Which you depends on the year of manufacture, or, when it was last changed.  Any new one bought will work in either engine.

Pieces coming along, pulled out a he distributor again and found the shaft release pin . I’ll s under the coil spring on the lower shaft. It made I so easy to work on and free it up. For only 60 k on it it was binding a bit. After removing the shaft the base found the base shims and phenolic washers wore into the base. Removed from he burrs and now perfect.  I also found a spare distributor that is in worse shape but will be a good parts donor for now.
  As normal I got a little carried away and polished more parts while sitting under a fan and relaxing with beer in hand.

  I changed it up a bit today and worked on my pedal assembly that’s been in a bag for 20 years.
I have all the rough dimensions necessary to fabricate . It was a struggle but I think I can keep must of it except for the base plate. I fabricated one up but will wait to weld up. I’m taking the Time to electro plate the individual pieces. Thanks certified...lol  another task to protect some items.
   Plating with nickel and it’s a first.

  Broke out the water pumps and will follow JB’S plan on adding bearings to the shaft . I need AC.

 Another delay is because I’m dead center in the now Cat 3 hurricane Dorian path . Readying the generator and all the other prep on Saturday. Took some pics to remind me what I might soon drive.

You and your family stay safe in the hurricane, D'man!

[Certified Lotus]

Dave, I’m smiling that your electroplating! Glad to hear you caught on    Your doing great work, and that black painted body looks fantastic.

Good luck with the hurricane. Stay safe.

I wanted to take the AC drive off the front pulley but I couldn’t figure how to mount the compressor for that location. 

[dakazman]

  Proceeded with the pedal assembly bracket and grease fitting modification. It’s now up to a point to weld it up. I added three key ways cut into the length of the clutch pedal shaft. This should distribute the grease along the entire shaft.
  What is a good orientation of the pedals foward and aft? 12 o’clock being the pedals straight up.
11 o’clock being pedal tips aft or towards the driver ?

  Another 8 hours of work on the pedal assembly I’m down to one more weld on the clutch cable arm.
The holdup was designing a stop pad on the base . My base was without any clue of where the clutch pedal adjustment bolt landed. With a tedious amount of tack and weld I think I have a working pedal assembly. I would have finished but a huge rainstorm blowing in all directions made me close up the garage doors. Tomorrow is another day.

  I received the new cam from Renault 16 during the week. Tappets on my mind so to build the 821wedge and the 843 crossflow. The machinist said to get a new set. I being stubborn said there
Must be a way to recondition the tappets. Drill press and 220-2000 sandpaper, with an added dose is oil. They are flat tappets. I only needed to remove the surface pitting. The po of the crossflow must have replaced my them. This is what the final product looks like . I will bring them back to the machinist to see what he says. One is for sure the 821 and the hemi.

They are not flat!  They are ground with a "crown" on them.  Usually in the 2° to 3° range.  The cam lobes are ground tapered to match.  They are also surface hardened.  Don't try to refinish them by hand.  It has to be jigged and accurately done.

I had mine redone and was very happy with the work.  I can dig up info on the place if you like.  It was a US shop.

Meca parts has new ones in stock again.
