Pop – Putting it Back Together

Hi folks, it’s Pop here.  Janet did an excellent job explaining basically the what’s and why’s of rebuilding her little 200ci six banger.  More air, more fuel, bigger spark, bigger explosion and more power.  Carl’s Machine Shop was fantastic, and now we have to assemble the parts.  This indeed trips my trigger and I will explain the procedure much to the boredom of some of you.  But, perhaps we can convert a few into budding “gearheads”.

We’ll begin with the bare engine block which was cleaned up, magna fluxed (a process to detect cracks…it passed), over bored 60 thousands of an inch (this is the maximum and was necessary because of scoring in cylinder #4, the result of a broken ring), and new freeze plugs installed.

The crankshaft went in first with .010” over bearing inserts.  This requires clearance checks using plastigauge.  Plastigauge is thin plastic thread which when compressed, spreads out and its width is then measured to determine clearance.  The top bearing shells are placed in the block, then the crankshaft, then strips of plastigauge across the bearing journals, then the bottom bearings and caps.  The bearing caps are then torqued to specs.  The caps are then removed and the width of the plastigauge measured.  I won’t further torture you with the measurements acceptable throughout the assembly procedure except to say, “everything checked out”.  (Janet: “Except to say we had to do math…math sucks.”)  The crank is then removed and turned over 180 degrees and the process repeated, assuring a straight bore and shaft.  Everything checking in specs, the bearing surfaces are lubricated, assembled and torqued to specs.  One final step, the crankshaft is then moved forward and backward to check end play.

The camshaft (which opens and closes the valves) was original and installed by Carl’s with new bearings, as this requires special tools.  (Janet: “Some of the only tools Pop apparently does NOT have in his garage. It’s just a matter of time.”)

Next, the pistons with new rings (which snap into piston grooves, hold compression and control oil on the cylinder walls), three rings per piston.  Before the rings are installed in the piston grooves they must be placed in the proper cylinder bore and the gap between the ends measured.  Too close a gap and the ring will break when it expands with heat, spelling disaster.  (Janet: “Apparently I got my dramatic nature from my father.”)

Each piston is fitted to numbered connecting rods then placed in the proper cylinder and attached to the crankshaft, plastigauged, lubed and torqued to specs.  With the installation of a new oil pump, the “bottom end” is now complete.

 

New timing chain (which goes on gears at the front end of the crankshaft and camshaft) is installed and the front cover and oil pan installed.  We’re now ready for our new and improved cylinder head.

One final and most important measurement is needed, valve clearance.  We now have oversized valves and increased openings with our new 1.6 to 1 rocker arms.  Heaven forbid the valves hit the pistons at top dead center!  That would again lead to disaster.  (Janet: “Need I say more?”)

IMG_4342

With #1 piston at the top dead center, we fill the space between the block surface and the piston with clay (in our case, Playdough).  We also filled #6, then install the head gasket and head.  The head bolts are torqued, the valve train assembled and adjusted and the engine turned over 720 degrees or two revolutions of the crankshaft (one revolution of the camshaft).  With fingers crossed, we disassemble the valve train, remove the head and measure the distance from the bottom of the valve indentations to the piston surface.  Yes!  We have clearance!

IMG_4329

The top end is now reassembled and the oil pump driven by an electric drill (the bottom of the distributor shaft will do this).  Checking for oil flow from the rocker arms aaaaaaaand – success!

 

Finally, valve cover on and new Ford blue paint job.

During Janet’s next visit we’ll install our Autolite two barrel carburetor with automatic choke onto the beautiful adaptor plate on the intake manifold.  Add our new 50,000 volt ignition and big exhaust headers and we’re ready to kick some ass.

 

(Janet:  “Pop and I have very different ways of showing overwhelming excitement.”)

Get Your Rear end Up!

Mavis has her rear end up, almost.  It’s so great to be able to start putting parts and pieces back on the car rather than taking them off.  So when I say ‘rear end’ I’m referring to the gas tank, back axles, differential, leaf springs, shocks, drum brakes and parking brake.  We also got the brake lines and gas line connected.  This picture doesn’t really do it justice, but here is the finished product of a shit ton of work.

IMG_2542

First thing up was the gas tank.  Those two long bolts can be shortened, but all that is covered by the back bumper eventually.  We also got the front of the leaf springs up and they lay in waiting for the differential assembly.

IMG_2461

We ended up keeping our original axles, but bought new bearings and had to get those pressed on.  Curt to the rescue!  We went over to his garage where he cut the old ones off (the ONLY way to get them off) and used his 40 ton press to press the new ones on.  He did the first one and let me do the second.  This machine is quite intimidating, you can crush things in it!  On approach, it looked like an industrial guillotine.

IMG_2419

Curt showed me how to place the axle with the new bearing. Here’s how it looks all ready to be pressed.

IMG_2421

Of course, me being who I am, decide I was going to be concerned that with all the pressure, the bearing may go on crooked.  I find things to be worried about, you see.  Here I’ve never done this myself nor seen it done and I’m telling a long-time veteran mechanic not to “put it on crooked”.  So, I deserved this.  Perhaps that’s why Curt wouldn’t accept any money for his work, because giving me shit was more satisfying.

 

Bearings, pressed and ready.

Back at Woody’s Garage we carried on.  Backing plate on, axles inserted, brake cylinder attached and brake lines in.

 

Pop says, “We’re a fucking machine shop!”  As much as you can call cutting screws shorter and rethreading them ‘machining’ things.  But we did have to come up with a solution to a brake line issue we had.  The main line was still in good shape (the line that brings the brake fluid from the master cylinder in the front of the car back to the axle.)  Where that line splits into two, we had to order.  Miraculously they fit, but for just a few modifications we made with a tube bender.  What didn’t fit were the fittings that connect them to the junction block where they split off.  BUT – the ones that were on the $100 piece of metal (the unusable axle we bought from Mustang Marty Miller) did.  Yes!  One less trip to the parts store!  We cut off just the tip of the ends, replaced the fittings and reflared the tubing.

IMG_2443

To do this, we had to use a special flare tool.  I don’t understand how Pop continues to come up with a tool for EVERYTHING.  We’ll run into a problem or a need for something very specific and his eyes get all big and his mouth says, “ooh” without any sound.  He puts his gorilla finger up in a ‘wait a minute’ sort of way and says, “I have just the thing.”  Then he rummages through the garage and comes back with the perfect tool to get the job done.  I think he’s jacked to be able to use what 60 years of tool gathering gets you.  It is pretty awesome.

IMG_2442

Flare tool, happy to be used.

Next up, getting the differential housing attached to the springs, the back end of the springs up and add shocks.  So here’s a big admission.  I didn’t know that the axle sits on the leaf springs.  I can’t say I knew how it was attached to the car at all.  I can’t even say I pondered this at any point during this project so far.  So when that concept clicked in my mind and I had that Aha! moment, Pop just looked at me and said, “How did you think it connected to the car? Did this not occur to you when we disassemble it?”  Again, I hadn’t really thought about it.  I was like, “What’ev.”

IMG_2464

We used the jack to hold the axle in place while we set it on the springs, secured the axle on the springs with u-bolts then raised the back of them and connected.  Who knew?!

Next, shocks.  One of the parts that must be bought new because they lose their gas and their ability to dampen motion, or in my terms, their ‘puffiness’.  Quick trip to O’Reilly and boom, new shocks.  It’s always exciting to get a new part…here’s me coddling $60 worth of shocks on the way home.

IMG_2387

One of the final steps was getting the brakes assembled. These are the second set of drum brakes I’ve done, as we had to put the Firebird’s back together to get it on its wheels and out of the garage at the very beginning of this project.  Still though, Pop and I had to dodge a couple errant springs.  We have the tool for getting them on, but not off.  So we work together with a screwdriver and pliers and wait to see who’s going to lose an eye.

IMG_2472

Although this all sounds like a lot of work, and it was, we still had time to fart around a bit.  Curt put Lil’ Big Rig up for auction so we went to that and watched him say goodbye to his baby.  We also took the opportunity to get under any 60’s Ford we saw to check out the parking brake system (which we also finished on Mavis.)  So everyone is walking around looking at these beautiful cars and Pop and I are like this most the time…

IMG_2484

Curt got close to what he wanted for Lil’ and it was the star of the show as it’s quite the site.  All chromed up and shiny.  Pop kept saying that someone should buy it to pull their 5th wheel camper with but I think it looks more like something a Country Santa with a cowboy hat would ride down Main Street in a Christmas Parade.  Well, we all felt for Curt as he had a lot of hours and TLC into that truck.  Couldn’t have been easy to see it go…but then he texted Pop a pic of a 1932 Ford Victoria kit he bought the day after.  Curt’s moved on.

Lil’ Big Rig

Momma, Pop and I also went to a car show in Somerset, KY where I got to meet Tony, the fine gentleman who donated a hood latch to our cause when he and Pop met at the Maverick/Comet gathering last summer.  What a great guy.  He asked me what it was about the Maverick that made me choose it for the project.  When I said that I just loved the shape of it, that it is a beautifully balanced little car, I think he teared up before hugging me.  Tony was at the show with Lemonade, his beautiful, supercharged 302 Mav, which Pop says is a ‘truly dangerous vehicle’ (in a good way.)  Afterward we followed him back to his garage where he literally, has Mavericks STACKED.

So, great last trip.  Lot’s of work, lot’s of fun and now the holidays hit. Next up on Pop my Ride, Mavis’s front end, disc brakes and more adventures.
