Builds Sky Blue 76

[orangefj45]

argh. That's not "good news".

 

[Skeet]

Stopped by the machine shop this morning. He said he's taken in 5 engines this week. He put me in line for the first week in June.

I was planning on resealing the engine eventually but definitely not rebuilding and not now. I suppose the bright side is that I can marry the trans/TC to the engine prior to installing. Not really much of a bright side...

 

[Skeet]

Should have it out tomorrow night

Bolts to attach to the 1 ton HF stand

 

[Skeet]

Those bolts are long enough for the 2 lower arms. The 2 upper arms that have to thread directly through the plate need 2 of these

Really deep grooves in the harmonic balancer.

Ouch!

 

[Skeet]

Those grooves seem to match the timing cover more than the seal. Maybe @65swb45, @FJ40Jim or @orangefj45 have seen it before...

This is all eerily similar to my '74 i just picked up. Following!

Interesting thread, you have the right amount of drive!

 

[Skeet]

Rebuilding the trans/tc. As @65swb45 has said, “the wear between the tail shaft and tc input gear is cumulative”.
Is there a remedy for the play between the two?

 

[Skeet]

Possible solution:
@orangefj45 sells a modified Terrain Tamer TC input gear with a longer contact area to engage the unworn area of the shaft. It doesn't state that it fits the 40 series, however. Anyone have experience with this part?

Just talked with Georg and those input gears won't work for the 1 piece TC since they are too large to fit through the PTO window. Only solution is new tail shaft and gear.

I just got done making the same assessment for @HKforte. All it took was this: put worn input gear on unworn section of tailshaft to determine how worn the input gear was. Take new input gear and put it on worn tailshaft to determine how much backlash noise you were going to hear under your seat every time you went from drive to coast and back again.

He had me replace both.

The truly sad part was that the input gear didn’t have a lot of miles on it; it was an Orion with maybe only 10k on it. But the previous rebuilder did not think the tailshaft needed to be replaced.

Sounds like money well spent on 2 new parts.

I stock them if you wish to purchase from me.

Ready for the machine shop

Half way there.
It’s hard to feel good about finishing the TC with that trans mocking you in the background.

Spacer between the trans and TC has a pretty good groove worn from the gear.
