2F Engine Block Reassembly : (FJ40 Week 38)

[@michingmallecho5143]

Loved watching this. Enjoyed your calm meticulous approach. This was educational for me - thank you!

[@knuckle47]

My 30 year passion has been restoring 1920’s - 1950’s American motorcycles… I know of no one who is as dedicated to quality like you are… I love this compilation of videos and I am going to watch every one of them…inspiring! Congratulations and much luck

[@lonewolfworks]

Appreciate it, it's been a fun project...the engine work was a nice change of pace from some of the rust repairs. Guessing the 20-50s motorcycles are some fun projects too, very much of the mechanical/analog age. Maybe that'll be my next project. :-D

[@thelandcruiserproject5421]

I just love the 2F, cool to see a rebuild.

[@lonewolfworks]

Simple, torque'y, and pretty bulletproof...and just a classic sound when running through the four-speed. It was nice to give it a good refresh after 122k miles.

[@estein63]

Awesome! Thanks for doing this video. We need more rebuild videos for these engines!

[@lonewolfworks]

Was a fun project...tried to catch what I could while doing it. The FSM is definitely handy...I had a paper copy, but there's plenty of PDFs floating around, too.

[@donnareed3822]

I just got my f2 long block back yesterday. Perfect timing. Keep up your great videos. Especially since I know nothing 🤷‍♀️

[@lonewolfworks]

If it came apart, it can go back together! 😁

[@bekithembasibanda6792]

Neat engine work

[@lawangean3655]

love tose push rads cam they were simple 😂😂❤

[@VengefulCarrot]

Hey man! Nice work, love watching your build so far. Going through my own similar build. Are you going to end up getting some sort of kit for your holley install? Manifold adapter, fuel pump block off etc... Interested to see what you end up doing :)

[@lonewolfworks]

I pieced my kit together from off the shelf parts, and some that I modified/fabbed up - saved a bit going that way, but I don't mind puttering. That footage is all just about ready for editing, but likely a couple weeks out to get it done. Been happy with the Holley system so far - the 2F is pretty smooth with it on there. I did jot down my parts list on the IH8Mud forums as well if it helps: bit.ly/34z1Vq5

[@VengefulCarrot]

@@lonewolfworks Awesome! Thanks for the info, and excited to see the holley footage. Thanks man!

[@randyharris9951]

Did you replace any of the freeze / Welsh Plug in the block and or head? Thanks for the videos!

[@lonewolfworks]

All the freeze plugs got replaced when it was down to the bare block (and head). They were probably ok, but good to do after 40+ years in service.

[@tomshumpert]

Great Vid.!! Lots of good info. Where did you source the new cam? Thanks

[@lonewolfworks]

Cam was just an aftermarket ITM - opted to avoid a regrind. RockAuto carried it, but guessing also available elsewhere.

[@richardguillot5189]

No journal pre oil?

[@lonewolfworks]

I did miss a bit of oil on the first round of plastigage fits, if that's what you mean. Later tests got a bit of oil, and everything got assembly lube prior to final assembly. (The oil pump got a long prime before first start as well.)

[@sawisfamily1]

What brand rings you go with? I’m doing the same thing now and have Hastings piston ring with the same .61 .66mm gap. Same book you have says no go.

[@lonewolfworks]

I stuck with Hastings, but re-ordered with a .030 set as they were readily available. My bores were .020 over, so the .030's then needed filing, but it put me into a factory-spec/typical ring gap. For whatever reason, Hastings seems to have shifted to a wider gap (likely being conservative)...but moving up a size with some filing did the deed.

[@sawisfamily1]

Interesting… I’m at a standard bore my engine only had 70k on it. Cylinders are tight at 94mm so I’ll call my shop guy Monday. Just happened upon your channel earlier this week so thank you for the time to post. 👍

[@lonewolfworks]

@@sawisfamily1 No worries...does seem like you hit the same "conservative" tolerances I did. Guessing you can either find a "file-to-fit" set, or maybe do the same play with some .010s. I did find a few threads online at the time that seemed to point to Hastings shifting to a wider ring gap, seems like it's true. :-p

[@triples4good]

I know that in building my CB750 engine there were main bearing options, A, B, C depending on the crankshaft number. Maybe that’s what you were seeing with your. On an unrelated note, do you have plans for your rotisserie? I’ve really been enjoy your build. I’m forced to take a 6. Onto break from mine. Just had rotator cuff surgery yesterday. My wrenching is going to be way down the road it looks like.

[@lonewolfworks]

That was my hunch as well on the bearings, but it seems like tracking those "sub-sets" are harder these days for the 2F at least...got there in the end though. No plans for building the rotisserie, a lot of it was just scrap pieces from the pile other than a few pieces of new 2" and 2.5" box tubing for the upper sliders...the spreader bar was a chunk of sprinkler pipe from a dumpster. Good luck on the recovery - rest up.

[@triples4good]

@@lonewolfworks thanks. Great fab work on that rotisserie but pretty impressive on the FJ too. Pretty cool that it was in the family too!

[@carlosbasabe8381]

Could you refresh my 2f engine?

[@lonewolfworks]

Sorry, I'm not a shop - just a hobby for me here. Industrial/truck shops can be a good option, as they're used to working the bigger inline 6s, and the 2F was used in forklifts as well.
