8.2 detroit diesel anyone???

[Whiskeydan]

I have a 8.2 DD "Fuelpincher" in my 2 ton F600 that has developed a front crank seal leak. ( Or, something very close to the front seal. )

I'm wondering if replacing the seal will require any special tool.

Any old diesel mechanics here familiar with the 8.2?

I did a short internet search to see if it was something I had worked on in the past but I was not. I have only worked on the oldrer 2 cycle diesels.
In general all engine companies have there special crank damper/pully pullers and seal drivers. If there is enough room use them you often do not need the special tools.
For the older 2 cycle engine (at the Long Beach Naval Ship Yard) there was no special tool for pulling the Crank Damper/pulley or a special front seal driver. But the tool room did have a large assortment of Jaw type gear pullers and such.
You have to use your own judgement. A jaw type gear puller with the jaws on the pulley can bend the pulley lips or even cause a separation of the rubber damper part from the rest of the pulley.
Most often the Crank Damper/pulley has drilled and threaded holes ready made for a puller. You need good quality bolts (grade #8) long enoug to work with the puller you are going to use and thick washers to go under the bolt heads. These are the safest to use as you are pulling on the correct part. If your local auto parts store cannot rent you one (often free) that will work there are tool rental shops that can.
Any auto parts store should have slide hammers with "Seal Hooks" to pull the seal out easily and they often rent them for free.

Is that the old 53 series, 71 series, or 92 series 2-cycle? If so, I'm pretty sure the front seal is housed in a bolt-on casting. So replacing the seal is easy with the pulley off. If not, should still not be a problem replacing the seal using common shop tools.

The 8.2 was a four stroke 500ci V8. The cam has three lobes for each bore. Intake, exhaust and injector pushrods are driven by these. Injection is very unique and complex requiring special tools, which are getting rare these days, to set up properly.
This was a common marine engine and is found in older school buses and med size trucks.
Its very fuel efficient but was unpopular as it was underpowered, not very rebuildable and could not meet emission requirements.
