Nice work! Always nice to hear an old tired engine roar to life. What year is the new Jeep?

Claims to be a '48, but it's hard to tell when parts have been swapped around over the year.

So small update, I removed the broken bolt that holds down the dist (ground smooth, center punch, drill in, then weld nut on, easy back and forth until it was free), tried to flush the water jacket but seems like it has a actually has a thermostat (bummer as it's probably frozen shut), and installed the engine mounts I was using in the 46. Everything was going swimmingly but for the life of me I couldn't get the engine to mesh with the tranny. Even after I found the spy window on the top of the tranny to watch the the shaft / clutch (durp), it just wouldn't seat all the way. So I pulled it out... freaking clutch is mis-aligned and I struggled to align it by hand. Well that put a kibosh on me getting it running for last weekend, but hopefully I'll have it running this week. Once it's seated with the tranny, I still have a fair amount of things to hook up, work on the timing, fill radiator to flush (also destroyed the old temp sender and when I used the extractor to get it out, the whole bushing came with it, so I need a new bushing too. Did I mention I also snapped the exhaust off the manifold? I'm going to using bailing wire to get it going but I'll need to replace that before the jamboree. Suck, felt like great progress and then stupid little stuff just stopped it. Good news is last weekend I work more on the cabin!

Quick update: Got the engine seated finally! Started reinstalling the everything and progress is rolling again. Hoping to drive it again soon. Btw this engine sounds good, totally easy to start and pures.

It lives!!!!

The heart transplant appears to have been a success and there are just minor things now like tuning the carb, adjusting the timing, replacing some old bolts, etc.

The water pump was peeing bad so I swapped on the water pump from the '46. Also I didn't care to use that antique alternator so I pulled that off as well and reinstalled my old alt (had to fab up and adapter, aka a piece of flat 1/4 with two holes). I did opt to reuse the newer fan, it sticks out a little more and has 5 blades instead of 4. Hopefully it will work well, the old engine got hot pretty often, but I think I pushed it pretty hard (being used to faster rides). Also pulled out the thermostat, I didn't bother even testing, assumed it was bad after 38 years of sitting.

So here is the breakdown of part swapped:
- Engine (block, head, internals) - from loaner (donor) 48
- Water pump - existing reused from 46
- Alternator - from 46
- fan - from 48
- Temp sensor - picked tinny stripped threads out of the 48's adapter and then installed the 46's probe.
- Starter - believe it or not, from 48, looks furry like it was used as a boat anchor, might carry the other as a spare on the trail.
- Distributor, et al - from 46
- Remote oil filter - from 48
- Radiator - from 46
- Clutch, et al - from 48 - makes an awesome sandpaper sound working away 38 years of rust.
- New: oil, spark plugs, oil filter. Also belt, but it didn't fit so using the belt from the 46.


I really would have liked lots of new parts but honestly I'm on a budget and I'm reusing every and all good parts, with some exceptions. Both jeep had cracked manifolds, so I order new ones from Amazon, I'm not looking forward to working with the exhaust studs again.

Pics!

Some ATF to break the thermostat out of the housing.

Cabling on the three cable alt (not pictured, ground cable to right stud)

Back together. My intake metal tube was loose on my jeep so I need another extension of soft tube before I can use the tube mounted on the head. The breather was off the carb because the carb was dumping raw fuel all over itself. Had to take it apart and adjust the float to drop the level in the bowl a little.
Image

I'll keep doing small thing on the engine, but now the focus is miles miles MILES of driving to make sure it's solid!

Going to look into getting seats new cushions and covers, including a rear seat! Also need to lift the body off one more time to clean and reweld the body mounts that are broken.

Ah I mean PCV... Stock feature, draft tubes are more pre WW2 on the willys engines.

Figured I touch one of my buckets threads.

So I'm sure everyone is caught up that the jeep did amazing on the Rubicon / Jamboree!
Image

When I was flat towing it home, I blew a tire, so time for new tires! I was a little surprised how expensive it was, but I did get awesome service from Bill's Tires in Pacheco. He works on lots of old stuff and my order included: four specialty tires ordered (650-16 size), new 16" tubes, mount and balance. The new tires have been awesome, and I'm stocked to wheel it more!

Image

Next up I have a broken front leaf (military wrap secondary main leaf means nothing happens, but it should be replaced.) Also I retrieved the engine block from the first machine shop, they said it was clapped out and I could tell they where not interested in sleeving it for me. I'll take it over to DDM in Martinez next, my buddy Ryan's was rebuilt there and they're next door to the horseless carriage club so they're used to old junk. :D
