FJ62/3FE sheared one of the serpentine pulleys (1 Viewer)

[TheElegantFox]

Alright, I think I'm going to coordinate with a local shop on getting this repair done but I need to do some leg work on parts supply, it looks like the main pulley is available from Toyota: Toyota Land Cruiser Pulley, crankshaft. Engine - 1347061030 - Genuine Toyota Part - https://parts.toyota.com/p/Toyota__Land-Cruiser/Engine-Crankshaft-Pulley/63133970/1347061030.html

As well as the crank key: Toyota Land Cruiser Gear or sprocket, crankshaft timing. Engine - 1352161010 - Genuine Toyota Part - https://parts.toyota.com/p/Toyota__Land-Cruiser/GEAR-OR-SPROCKET--CRANKSHAFT-TIMING/62993127/1352161010.html?clickSource=relatedProduct

Would this be a good way to go?

You're going to need a new timing cover seal, also.

Hard to tell from the one pic, but is your keyway on the crank snout wallowed out or ok?

For the Harmonic Balancer certainly you can't beat the OE Toyota, but there are aftermarket from Dayco that are under $200 if the price of admission of the new OE is an ouchie. I didn't read where 3_pups said he had a used 3FE pulley, which would be fine, too, if available.

Good luck.

The keyway seems intact. Which part would be the harmonic balancer?

Looks like the timing seal is still available direct: 1132861010 - Gasket, timing gear or chain cover. Engine - Genuine Toyota Part - https://parts.toyota.com/p/Toyota__/Engine-Timing-Cover-Gasket/62991446/1132861010.html

HB is the pulley that disintegrated.

You're very lucky that thing didn't let go at high speed...

Also, you linked to the Cover gasket... The round rubber seal that is around the crank snout is what will need replace.

And you're gonna have to find a new crank nut. NLA from Toyota

Ah ok so harmonic balancer = crank pulley.

Looks like these folks have a crank nut: https://shop.cruiserparts.net/index.php?main_page=product_info&products_id=39667

Would this be the seal needed? https://shop.cruiserparts.net/index.php?main_page=product_info&products_id=61917

Looks like I can get the belts from here: https://www.coolcruisers.com/fanbetofj81.html

and a replacement for the shredded fan: OEM Radiator Fan for '79 to '90 Land Cruiser FJ40 FJ55 FJ60 FJ62 - https://www.cityracerllc.com/products/oem-radiator-fan-for-79-to-90-land-cruiser-fj40-fj55-fj60-fj62-1 I need to verify that I've got an OEM fan blade/housing first though. Also looks like a used one could work: https://shop.cruiserparts.net/index...info&cPath=2_4851_3270_3288&products_id=33237

 

[Spike Strip]

Those all look good.

If you look on rockauto.com you can get the Aisin fan (OEM) for around $40

The correct timing cover seal is linked above. Looks like below:

I do have the pulley, nut and most likely a key, trying not to peddle wares in tech.

the seal can be finnicky in the timing cover, caution is advised, the cover is easy to deform if using extra force

We can try something in the DMs

Any better pics of the crank keyway? The sort of failure that I see in my nightmares. One of my biggest fears running my 2F daily is the HB letting go at speed. As @Spike Strip mentions very fortunate this wasn't worse. GL.

This is something you really need to verify

 

[Spike Strip]

Need a pic of the 'trough' (keyway) that's cut into the snout

Need a picture of where the keyway is inserted into the crankshaft. Its not in this picture.

 

[TheElegantFox]

Ah ok, do I need to disassemble further?

 

[tmxmotorsports]

No you should be able to get a picture of it as it is.

 

[Spike Strip]

In your other pix it's at about 7 o'clock on the snout if you haven't moved the engine

 

[TheElegantFox]

I was totally turned around on what I was supposed to be looking at, here’s a picture of it

It doesn’t seem mangled at all.

Alright, after working with 3_puppies(many thanks!), I've sourced the crank pulley/harmonic balancer/crank nut/key + fan blade/shroud. I've ordered a new set of fan belts and an oil seal. Should that be about it for the parts on this job?
