Stevo's Unofficial Build Thread, FJ60 + FJ62 + FJ80 Axle = FJ68?

[StevoJonesFJ60]

I'm going to throw some lucas stop leak in the engine and hope that helps for now. I really don't want to dump a whole lot of time/money into this engine while I have a perfectly good 6BT just chilling there in a truck I will never make street legal.

I came home to find some more upgrades for the Cummins. This compressor upgrade will be going in shortly.

 

[StevoJonesFJ60]

dude who has been shooting at your diff? haha

Yeah.... I realize I sorta went nuts on the armoring of my axles. They were out, and I had the metal, and it just happened.

 

[StevoJonesFJ60]

Most of the upgrades have been installed in the cummins and I must say that thing HAULS! It throws me back into the seat whenever I get on the throttle, and I love it.

Even pinned the EGT's are only around 900*F pre-turbo. And I'm pushing around 25 psi boost. I still need to add the timing spacer and turn the pump up. Once thats finished I'll mess around with both trucks for a while until something big fails on the Cruiser.

Bronson is finally going to be street legal tomorrow.
I can't wait to drive this truck to some wheeling spots.

 

[StevoJonesFJ60]

Well after driving the truck around for a bit, I had to admit that the leak was getting worse.

Good news it that I have found the leak to be from the crankshaft. Would this be considered a timing cover seal or crankshaft seal?

 

[TLC Norway]

looks to me like a crankshaft seal, but lets see the engine pics. Hose it down and let it run while watching.
that is not a leak. its a hole!

 

[GLTHFJ60]

Front main or timing cover.

Are you positive its not coming from above?

 

[StevoJonesFJ60]

Yes it is a crankshaft seal, I had one of my belts too tight and it must have ruined the seal.
I could tell because when I loosened up the belt, Oil began to rain from the crank.
It annoying to get the truck on the road only to need to do more repairs, but at least I know what it is now and that it isn't my timing cover gasket. That would be a lot more work to repair.

 

[StevoJonesFJ60]

What exactly is the front main seal?

I also had a little fun in the diesel last night.

It sorta was a combo of both.

What exactly is the front main seal?

Same as the rear main but smaller!

Thats a mighty big leak you got going haha

 

[StevoJonesFJ60]

I took apart the front of my engine today in order to replace my front timing cover seal. Thanks to the site I found that I could easily break the retaining nut free with the use of the starter, which worked great.

I then proceeded to pull off the pulley to find a nice groove worn into it.

Does anyone happen to have a picture of what the pulley should look like new? Or even better yet, be able to grab some dimensions so I can repair mine.

I figured oh well I might as well try replacing the seal to see if the problem was just the seal, unfortunately it was a combination of the two. Fortunately I have everything I need to repeat the process now and don't need to spend any more time making a SST to hold the pulley stationary. And for the record having access to a torque wrench that went to 304 ft-lbs would have been nice, but a 24" breaker bar and 280 lb grain scale works well in a pinch.

Good to see it was (hopefully) a fairly easy fix (as opposed to something that could've damaged the crank or valve train).

 

[StevoJonesFJ60]

Yeah it was a pretty easy fix, unfortunately I'll be needing to do it again sometime this week to get it ready for a wheeling trip to the pines this weekend.

 

[StevoJonesFJ60]

Well I took the truck out a bunch saturday. It was fun bringing a bunch of friends on some trails.

At one point I had 6 girls in the truck with me.

Today I pulled the belts again and took off the crank pulley. I have to say using the starter to break that big nut free is definitely the best way to do it. tomorrow i'll have one of the welders fill this groove up and I'll turn it down in a lathe.

Its obvious that that I might have a trashed bearing or something to cause this much damage, but I'm banking on the repaired pulley lasting until I'm ready to swap that 6BT in.

Pics or it didn't happen

Cruiser looks good. I like the mud job. Only cause its not mine! Haha

 

[GLTHFJ60]

HOLY s*** that's a hell of a groove. There is no way there is that much movement in your crank. You would have needed to break the damn thing in two to get that much play!

 

[TLC Norway]

i hope it's the small darker area to the left that is the groove...
the BIG groove on the right is machined like that, right?

I wish, that groove on the right is the one I'm repairing. Its all done now I just need to paint it up and reinstall it.

It looks like this now.
I just need it to last me until my new engine is ready.
