SEIZED ENGINE REBUILD - Ya don't wanna go through what I am!

Posted by Ken McWilliams on September 27, 2001 at 05:42:29 from (38.232.245.248):

I bought a CASE 310D crawler a few weeks ago with a seized engine. It had sat outside for several years with the exhaust pipe unprotected. I tried several methods to break it loose, but concluded that it would have to be taken apart.

When the head was removed, #1,#2, & #3 were badly rusted and #4 was unaffected. I pounded on the tops of the pistons and couldn't move anything. The engine was still in the crawler, so I got under it and pounded on the piston's wrist pin bosses to no avail except to break chunks off of the bosses.

The journals on the crankshaft were positioned at 9:00 o'clock and 3:00 o'clock. I loosenened the rod caps and got #2 & #3 to move, but the rods couldn't be removed because the journal position caused the rods to hit the block and prevented them from being removed out the top.

I removed the engine from the crawler, and placed the engine on a stand. With the engine up-side-down, I then, loosened and lifted out the crankshaft. Then I drove #2 and #3 out the top of the block. They broke loose reasonably easy. Piston #1, however, wouldn't budge. With nothing to lose at this point, I pounded on the bottom of #1 piston until something started to move. It drove the sleeve out with the piston! Afterwards, I needed to salvage the connecting rod, so I had to split the #1 sleeve down the side with a grinder to remove the piston.

Here's the surprise. I'm getting ready to buy a rebuild kit. It is supposedly a Gas 148 engine with 3-3/8" bore (at least that's what all the specifications that I've seen indicates). All 4 sleeves measure 3.435" bore. Three of the pistons measure 3.425" diameter. Piston #4 measures around 3.350" diameter. The #4 piston shakes loosely in the bore.

The #4 must have really hammered while running after the previous "rebuild". The former rebuild on this engine looks to be somewhat fresh. The #4 piston didn't have any carbon on the top, it was still bright and shiney. The valves and springs were new, and it had a fresh mill job on the head.

This crawler doesn't have a Gas 148 engine, but some other size. What is it?

Who ever rebuilt it assumed it was a G-148 engine. A G-148 piston (assuming a 3-3/8" diameter bore) was installed in #4 bore, but it didn't fit by about .075" on the diameter. (3.350" diameter piston in a 3.435" diameter bore.)

Can anyone tell me what engine is in this CASE 310D crawler?

Here's the data:
Crawler S/N 3014456 It should be a 310D?
Engine S/N 277S10202
Engine Casting number: GWC / D270
Connecting rod number: G-11340 (Maybe G-11840, the "3" could be an "8".)
Bore measures: Actual = 3.435" (Should be 3.375" for a gas 148).
