Sylvan Sanctum (?) - Ford E350 7.3 Powerstroke Type III Ambulance - Family Van

Here's what I got off... (baby steps, baby steps...)



Pulley seems fine, so I might just try to get someone to press in new bearings for me.

Yeah, Id say those bearings are toast :sombrero:

My Mccoy miller conversion high idles if the parking brake is on......

All ambulance should high idle with p brake on. Federal requirement for certification. Some people are startled and think it's a runaway. Some are convinced the engine Will scatter and never use it.

It will be interesting to see how this requirement is impacted by all of the new EPA anti-idling laws. Maybe, they will issue a waiver for emergency vehicles or something?

And there was much rejoicing:



I bought bearings (Nochi $5 and change) and knocked them (gently) in with my wife's help, heating the pulley on the plate on the stove and pressing ice on the bearing between whacks. Remounted the pulley, put the belt back on and fired everything up. It works!

Current project: removing the driver's side rear cupboards - to clear the wall for windows.

Also needed: a front-end alignment.

Looks good, and I know you're glad to get that done! Now on to the fun stuff..

That's an interesting looking hammer.

 

[IdaSHO]

Also looks to be a shielded bearing instead of a proper sealed bearing

 

[Herbie]

That's an interesting looking hammer.

Straight-pein hammer - a blacksmithing tool. The narrow edge allows thinning material via fullering against the anvil. Similar to a cross-pein, but more ergonomic for certain kinds of work.

What will that mean for me? The bearing bits that were left didn't show me rubber seals or anything, so I just asked for the metal ones.

Got it, thanks!

The photos of the destroyed bearing you posted shows the seal(s)


Running shielded vs sealed...

The bearings will run cooler, but will become contaminated and fail sooner due to the metal shields not sealing as well as the rubber contact seals.


Would I swap them out now?


Probably not. Just be sure to use the correct bearing if/when the shielded one fails.

It could very well last forever, but being under hood in a vehicle I really doubt it.

Moisture intrusion will be its downfall.

I have to change the tensioner on my 460 every year. It gets packed with silt, the bearings are junk.
