2f engine, pistons and head.

[tltaylor22]

Yep - that looks like what was in my oil pan -

on the SAS 8 thread, this morning someone offered an 1987 2f this they said is running for 1500 - in Colorado I think.

Yep, already messaging with @mesa man

I'm up in Orem Utah

Ah, ok. I’m doing a bunch of shuttling between central Texas, northern New Mexico, far west Texas, central Texas and back to northern New Mexico the next couple weeks if any of that helps.

Best of luck to ye!

Last night, I pulled every bearing off except the front main. Darn thing wouldn't budge. All of them looked really good. All the first pins were torqued correctly as well.

 

[OlYellr]

Good grief. Head scratcher. Strange how the front wouldn't budge with recently going together. There are two different torque specs to use with the main bearings - 1 through 3 = 91-108 ft-lb and #4 bearing is 76-94 ft-lbs. I know you know that, just streaming of conscious going on with my fingers as I am trying to think this though too.

I very much admire your fortitude in taking this on. Every so often, I get the urge to find a 2F engine and rebuild it to have as a spare for when the transplant becomes necessary. Then I read threads like this and the exploits of @OlYellr and I come back to reality. How painful it must be to put in all of that effort and expense not only in rebuilding the motor, but also getting it installed and everything that entails, only to run headlong into a brick wall. I'm afraid that when the time comes, I will chicken out and have a pro rebuild and test the motor.

I got your back - and maybe a spare engine for ya in the garage that is a good rebuild candidate (not sure what I want to do with it yet - I got it due to the price and not sure how mine would finally end).

It was a huge learning process and glad I did it. I smile even more to myself when I accelerate going up a long hill knowing I did that.

I'm assuming the front wouldn't come off due to some gasket adhesive between the timing plate and the bearing. I'll get it off tonight. Not that it is seized or anything. The metal in the oil pan was concentrated in the first and second baffle.

I've got my original motor sitting in the corner of the shop but Its a basket case. It only has 1000 miles on it but the machine shop machined it .010" past the .030 of the new pistons. My only option on that one is to find a set of .040" pistons and have it machined somewhere more reliable. I can't even hold them accountable as they did the work 20 yrs ago and I thought the ring just didn't seat and didn't work on it for 20 yrs. Life is too busy.

 

[tltaylor22]

Finally got the front main bearing off tonight. Not a scratch on it so I still don't know where the flakes came from. I threw some new plastigage on it and torqued it down to 105 ft lb. I wiped the bearing and crank dry first. I expected it to show it was a little tight but it actually came up loose between .076 and .051mm. So strange as these measured better than .038mm when I built it. Maybe the crank was knocking? The bearings that came with the motor were .25mm and I just threw in the same as the crank seemed to measure for that. This is probably my knock but I still don't see where the flakes came from.

New update, new motor. It's been an epic weekend. My boys and I left northern utah on Thursday at 3 pm and headed down to Sante Fe New Mexico to meet up with @mesa man and @Mesa Woman to pick up a 1987 2f. Awesome family! It had been a few years since I'd driven down there. I used to live in Gallup.

We were back home Friday night after a quick detour through Silverton Colorado. By Saturday night the motor was installed with all new main seals, oil pan gasket, timing gear and side panel gaskets. The sm420 is always fun to install but no one was hurt so it went pretty well. The goal is to get her running tomorrow night.

 

[mesa man]

It’s so very awesome this 2f found the perfect home with a motivated family! You guys rock!
Keep up the great work, quality father and sons time for sure!

Keep the pics coming Trent! Thanks man!

 

[Mesa Woman]

So…. Is it running yet??
I hope all went well and continues to do so!
It was a pleasure to meet you and your boys!

Busy week this week. I'm now on a boat in Alaska but we got the fj40 up and running. I temporarilyremoved the FI (it'll go back on when I get home). Threw a carb and then struggled with my fuel pump. A quick trip to to @cruiseroutfit got me an 88 pump. Now we've got full fuel flow.

 

[tltaylor22]

Kyson and I headed to the hills tonight for some senior pictures. Still lots of things to do but the kid was pretty happy. He did say the 80 series is smoother on the same dirt road. I just laughed. That's not really the point.

 

[cruiseroutfit]

Woohoo, glad it's moving...

 

[tltaylor22]

The time capsule continues to give. While a poor college, I found an trampoline and converted it into a bikini top. #tramptop. It came out of the archive tonight. The boys were dying. Not exactly the refined look for a frame off restored cruiser but it has awesome history.

At the same time we found the Lowes ABS pipe snorkel that still has the hole cut above the fender. It hasn't been installed yet but it's coming noon.

 

[mesa man]

Resourcefulness! Love the happy faces!

So after a few weeks of driving, the clutch is struggling to fully disengage. It has a brand new 1976 master and slave. My good friend is suggesting putting a 1969 brake master in as the clutch to use the 1" bore to get another half inch of throw. Anything else I should look at first?

Do you need to adjust your slave cylinder pushrod?

 

[tltaylor22]

Do you need to adjust your slave cylinder pushrod?

Busy few weeks. I've adjusted the push rod and limit bolt again. It's definitely better. I'll keep dialing it in.

 

[tltaylor22]

I think parts of the clutch issue is that the acorn style nut on the slave cylinder seems to be digging in deeper and deeper j to the fork hole. I'll dig into that and see what I can come up with
