Don't do much pulling on the flywheel by wedging between it and the face of the block. Same for driving/hitting on the end of the crankshaft etc. The main bearing on the opposite end is also the thrust bearing and it is held in the block by a dowel pin which has come out on many a pony motor. This will result in the crankshaft moving in and out as much as 1/4".
the pony motor is covered in the SRB for the engine. In your case the D318 4 1/2" bore 6 cylinder diesel
Here's a pony specs page for the dimensions.
Every flwheel I have pulled was with two ball peen hammers and a cat bar. Place bar behind flywheel to hold away from bearing. Place ball of one hammer on end of crankshaft and tap the head of hammer with second hammer. Saves a lot of time.
Never had a problem pulling flywheels as Cat recommended.
In the shops I managed you would receive a safety violation writeup for using hammers in that fashion.
I ended up using a 10-ton two leg puller on mine, along with 12 months of soaking with PBlaster and then some heat. It was on there.... Echo the comments being careful with hitting the crank axially - it doesn't really stand up to that sort of activity too well. Since you're going to look at the crank, take advantage and check out the bearings and the fit with the dowel - if it's at all loose, drill a new hole.
Cheers,
Neil

Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
