1947 CJ2A
Blog Collection

I'm planning to jump back in to the CJ project early next year and I'll be opening up the engine again to try to be sure I do it right this time.

I want to get rid of the canister oil filter with a remote filter kit.

The head will be coming off and I need to drill out and tap the area where the temperature sender attaches. Looks like 3/4 inch pipe threads. Cheaper of 25 available taps:

Drill for tap. I'd like to find this size in left handed also, but can't find any this large.

Distributor will be popped out and will be turning the oil pump with an electric drill to make sure it works and primes all of the oil galleries.

Then everything gets zipped up again and retimed.

After we get it running, brake work is next. Though I'm pretty sure it hasn't had brakes for 45-50 years.

We had some decent luck this weekend. This next week we just have to hook up all of the vital stuff to see if I did the engine reassembly correctly. The engine popped right back in to the transmission. Those clutch alignment tools are a must have when doing this deal.

I got the block back from the machine shop on Saturday morning and started cleaning up some of the nuts and bolts and these parts in the photos. The shop installed new exhaust valve inserts that should hold up better with the unleaded gas that we now use. They also went through all of the oil galleys, installed new freeze plugs, checked the valve guides, and cleaned off the head nicely.

Today, Lisa and I were running around town, and we got some high temperature Rustoleum semi-gloss to spray on the engine after all of the time spent on cleaning it up. Another coat goes on in two days after the paint fully cures. I know this isn't the perfect way to do this, but I figure this is better than what we had before, which was no paint and a whole bunch of rust. I also got the old rings of the pistons tonight.

Next Saturday we go back to Toledo for a few final parts before reassembly:
160 degree thermostat
Thermostat retainer
Radiator cap
Connecting rod bearings ( .010 under)
Main bearing set (Also .010 under)
A couple new rubber oil lines
Throttle cable ( To set a constant engine speed with your foot off the gas pedal)
12 volt gas gauge since we have a new fuel tank and sending unit.

The machine shop only had to polish up the crank and hone the cylinders a little. So there was no need for new pistons and all of the extra expense.

1947 CJ2A and the weather from Harold on Vimeo.

I got a couple of valves out and was told they needed replaced. So we made a shopping day of Saturday and Lisa and I went to get a few things. Each of her parents decided to get each other a new bible for Christmas without the other knowing about it. Lisa was told what to find and we hit the Barnes and Noble in Toledo first. One needed to be a New King James version in large print and the other was to be just a thin version of the new testament and psalms to save weight since Lisa's mom doesn't have that much strength.

Then we hit the parts store for a set of standard piston rings, all eight valves, mechanical temp gauge, and a parts list manual which has exact sizes of all the hardware and really nice exploded views of everything on the Jeep.

Last stop on the trip was at the pharmacy of a hospital. Lisa's mom needs a quarter CC subcutaneous shot of a vitamin, and the only way to do that is with a tiny one CC syringe.

On our way home we visited a Max and Ermas restaurant. Lisa had half an order of ribs and I had a Rueben with parmesan garlic fries. It was all yummy other than both of our meals being a little cool. One of my sprite refills was missing the syrup and was plain soda water. It has been quite a while since that had happened, it's a VERY distinct taste. Wink

After getting back home, I got the rest of the valves out and saw that the next operation will need to be done by a machine shop. The #3 cylinder had the exhaust valve stuck up for quite some time, and the valve seat had become rough and pitted with rust. I'm going to see if they can set in some hardened valve seat inserts without me having to tear the engine down to a bare block. I imagine I'll also see what my options are for them to do a whole rebuild and general check of the whole thing.

Now to see if my Vimeo embed takes. Smiler

EDIT: I pasted in the Vimeo embed code. I guess I don't quite know how to do that now.

I'm finally getting an indication of the current engine issues.

Cylinder #1 is fine with both compression and exhaust.

#2 + 4 seem to have sticking intake valves, they weren't trying to suck in my index finger the way that #1 was. But they were blowing back out just fine.

#3 either has both the exhaust and intake valves stuck or bad piston rings.

One of the shop mechanics at work said that a burned out head gasket can cause some of these symptoms too. He even offered to look in to the engine since that's something I've never fooled with.

I'm planning to get some bolts with the correct threads to screw in to the spark plug holes to safely lift off the head and I guess we'll go from there. I'd like to do this work with the engine in with out having to pull it out again.


On other stuff today, after we played pretend auto mechanics, Kyle and I went to a ham shoot at the county coon hunters club. With each round costing $2.00 each, we went for five shoots each and came up empty. We then went to a turkey shoot at one of the local volunteer fire departments and participated in their raffle and four or five shoots each. I finally got one to bring home. I had forgotten how steady you have be for these things. This was Kyle's first time using a 12 and he did pretty decent with it. We'll work on his aim later if I start reloading the empties that have been saved over the years, in the future.

This Geecast also contains "CJ2A - Day Ten" details.

I had a pound of hamburger thawed out and Lisa and the kids went into town to take care of Lisa's mom. Lisa has been helping 24/5 during the week as her mom needs 24 hour care and they don't care to fool with a nursing home now. Anyways, all that I should say about my meal is that Hamburger Helper makes better meals than this one. Too bad I can't remember which ones those might happen to be.

While cranking over the Jeep, we could see the gas going through the fuel filter, so that shouldn't be an issue. We also confirmed a spark on all 4 plugs. But we still achieved a "no start". KYDave was probably right about the carb being a mess. Lisa will be in Toledo tomorrow and she's going to pick up a new Solex brand carb. I've read good things about making the switch from the OEM Carter brand to Solex, so now seems like a good time to do that instead of fooling around with a rebuild kit that might not get the job done.

Kyle and I got the garage cleaned and most of the tools put away. Then we pushed the Jeep up to the wall and pulled the 140 to the garage and pushed it in. The sediment bowl had a crack in its' aluminum casting and had been leaking this fall. I got the fuel line off and then broke off the threaded portion of the casting that stayed in the gas tank. After that I quit for supper. Wink I think round two on the Farmall will involve drilling out the casting as much as possible and an easy out. I also think that the starter switch is still ok. The positive battery cable is shot and needs fixed or replaced. The ignition switch is going bad and it will get replaced along with the light switch so I can blade snow in the dark after getting off work this winter. At least that seems to be the current plan.

Have a good evening. Smiler

The engine cranks over nice just the way it should. The only problem is not having enough gas to throw into the tank. I also measured the placement of the fuel pump as compared to the gas tank, and it's too high. This model of fuel pump will only pull up one foot and we are over that. Tomorrow I'll get some more gas and move the fuel pump lower. Then we'll know if there's going to be carb issues or other things that will need to be cleared out.

My duties today were the alternator and wiring. Kyle's job was to install the exhaust and he did good.

Kyle and I got another new tire mounted in town and picked up some bolts for the towbar bumper clamps that we made Friday night and some jewelry. We got both of the new tires on the front end and got the towbar on and the jeep followed us home. Smiler Three of the wheels have right hand threaded lugs and the left drive is left hand threaded.

Both of the transfer case levers loosened up nicely on the trip over. I blew out the gas line to the gas tank and the fuel pump still wasn't sucking anything through. We got the radiator out and everything else undone and had half of the bolts on the bell housing off on the passenger side. We got under the left side and I realized I had gas dripping on me. I drained the gas tank and took it off. It was pitted and had a few pinholes. So a new gas tank is on a long list of parts that we want to get. Along with a water pump, new brake cylinders, brake lines,  rubber hose for the oil pressure gauge, all of the clutch parts and new flywheel.

The engine does crank over with the battery fully charged, which is the only good sign in the project. I'll get the stuff we need for the 12 volt conversion and we'll have that out of the way. (One wire alternator, alternator pully, 3.0 ohm coil, 12 volt starter solenoid, new battery, 12 volt fuel pump.) I'm not too sure if I'm going to have the starter rebuilt right away.

I guess we'll go to Toledo for most of the OEM parts and get the engine yanked out. The transmission jack should be here on Monday. I ended up having to order the one that I wanted from www.northerntool.com .

I would have posted a whole gallery, but I'm having some issues with getting the photos off our digital camera.

Kyle and I went over and got the new tire on. We aired up all of the tires better and then my brother Marv pulled the jeep out of the barn with a tractor. It seems it was stuck in gear and the shifter was stuck. I got it loosened up and out of gear only to find out the clutch wouldn't disengage with the clutch pedal. It was loose. We had to stop every time I wanted to pop it in or out of gear. I'll need to figure out what I need to do about  this. The engine was also stuck a bit. It freed up after a little dragging down the driveway. We got it parked back on some cement and under a roof and we cleared off raccoon poo by the shovel load. Kyle blew off the dust with the air compressor and I threw on some penetrating oil around a few spots and that was our day.

My mom said I might as well take the jeep home with me to work on it. I'll be picking up a tow bar in town and we'll get it moved next Saturday. I'll have to get some advice about what to do with the clutch. I'm hoping it's an easy fix. Otherwise, I'll have to get an engine hoist and pull out the engine to get to the clutch. I had Kyle work the clutch pedal back and forth and I didn't see anything wrong with the linkage. There's also another dramatic problem. Lisa forbid me to continue with this project after barely getting started. I think she's just being a little pessimistic. Wink Although I will admit that this has become much more of an involved project than I was expecting. I was hoping to simply throw some gas in the tank and that would be it.

We went looking for the oil breather and couldn't find it. It didn't get put back on after we put in a rebuilt 1951 engine. While looking around we found the original 1947 engine in the other barn. That made my day. I thought it had been traded in for the rebuilt engine. All three of the serial numbers should match with that engine. ( Engine number, body number, and the other main tag, I think. )

Water is coming out of the water pump's seep hole. So that means a new water pump is due. I also put a couple gallons of gas in earlier, but the tank was dry today. I'll have to check that out too.

Now I'll be studying the service manual. It only has 6 or 7 pages devoted to the clutch, but all of the info needed is there for refurbishment and adjusting.

We are planning to hose it off with the power washer and I'll try to get some more, better, photos put up next week.

Kyle and Lisa and I went over to my Mom's to visit and spend some quality time with the Jeep. I got the new ignition switch plumbed in, I didn't even run the wires through the firewall. Smiler Then we tried cranking it. The electric fuel pump was running fine, but the starter wouldn't move. It sounded like the solenoid was doing it's job, though.

Kyle jacked up the back bumper and I took off the blown tire so I can get it replaced. I think Day Four will involve pull starting with a log chain and the pickup or a tractor. If we get it running yet this fall, I'll replace the plain water in the radiator with a 50/50 antifreeze mix for the winter. If we achieve a no-go, I'll probably just open up the drains instead.

Kyle and I snuck over to do a little more today. I got all of the sparkplugs out, threw in some penetrating oil, and popped the plugs back in. Then we decided to move the jeep. I have manual front locking hubs on the pickup, so I locked those in. The only way I could get the jeep to move was by going in low range four wheel drive. That's the first time I had ever gone into 4 low like that. Then we picked up the tools and got the shop manual for the jeep from my mom since I have to get the starting circuits figured out and a new switch installed. In the first GeeCast, you'll see a starter selenoid on the firewall. In the wiring schematic that I scanned in, there's no selenoid, just a foot starter switch, which isn't there. I'll have to figure out what goes where in this setup. I thought this used to have a push button starter switch on the dash, it isn't there now. If you can't tell by now, I'm not a formally trained mechanic. Smiler

My stepson and I spent most of our afternoon on this new project. Actually it's an old ongoing project from 25 years ago that is getting revived this summer.
