Tear Down of a RB Industrial Engine

[Dutchrebuild]

Bought this beast for a song yesterday...now time to rip er down. Pretty much everything gets scrapped except block and crank and some trinkets. Was advertised as a 440 but of course it's probably a 413. Supposed to be a 1977. The front pad has nothing stamped on it.
The block casting number of 40068081 is a complete unknown to me...and I thought I knew them all. Bore measurements will tell all!

Ready to go on the engine stand...and the scrap pile grows...

The balancer is unique to steel crank industrial RB engines.
The whole distributor set up is also unique

Looks like you got a free distributor spacer. Nice.

 

[Dutchrebuild]

Yup... usually only on marine and industrial engines...don't see them on motorhome versions

That tag on the valve cover should be punched for the engine size. Most likely came out of a 700 or larger truck. For sure not a motor home with that ignition, carb, and governor.

Interesting, I've never seen a Holey tag on a distributor before.

Manual tach drive. What did it come out of?

 

[Dutchrebuild]

Believe it or not, I bought it from a Amish guy....he thought it was from a ditch digger

Probably a reverse rotation engine, may have adjustable rockers. Crank oil seal surface ////// maybe wrong \\\\\ if you use it on standard rotation build. Remove them and put correct ones? To costly?

 

[Dutchrebuild]

No evidence of reverse rotation...normal car starter

Normal rockers...and evidence of a rebuild...bore is .040 413

Manual tach drive. What did it come out of?

The HD trucks of that vintage also had a cable drive tachometer.

Painted red might make sense in the industrial line. All the 70 and newer as I remember were light blue in color.

Typical with HD Truck and industrial.

 

[Dutchrebuild]

That's it for today! Gotta prep for the horrible weather that's heading out way. Tomorrow I'll tear down the short block...stay tuned!

Did Holley remanufacture distributors?

 

[Dutchrebuild]

Date coded to engine with a Chrysler part number

Did Holley remanufacture distributors?

Probably because of the governor.

Is that intake exhaust or coolant heated?
