Removing pony motor from flywheel housing

More
4 years 5 months ago #216164 by Dan
Hi All,
I haven't pulled the pony motor off my D2 4U crawler before, but now it is necessary. I have disconnected everything required including all the sneaky cap bolts and nuts. Now I find the engine is securely stuck to the gasket stuck to the housing. Using a sling in the manner shown in the service manual, my question is, how much force can be applied pulling upwards before damage occurs somewhere?
Thanks for any advice,
Always appreciated.

are you sure you got all the bolts out? I forgot what the count is--someone should come along with the number

Two nuts on the left side three nuts on the right and three capscrews between the diesel block and the starting engine from the left side.

Hi dpendzic.
I'm pretty sure I removed all the nuts and cap bolts. 3 under the right cylinder head, 3 under the left cylinder head in an L shape configuration, and 1 longer cap bolt and 1 shorter cap bolt between the pony and diesel engines. by my count it's 6 nuts and 2 cap bolts, 8 in all.

I recall eight (8). Two in front; two on right side Beneath Spark plug ; one on left side Beneath spark plug; one tucked in corner behind the pinion oil cup; two on rear on corners each side of flywheel. Two dowels.

Whe I removed mine the first time a few years ago it was a little tight. Pull it backwards there’s more movement and it’ll free it up off the main to starting engine coolant chamber seal. Make sure the exhaust isn’t getting jammed under something. Drain oil and coolant and remove the compression lever. Don’t pry corners too hard.

Have Fun!
Bernie

Yes your right, just keep lightly nudging it with a pry bar, it should come loose. This is the base gasket. Small holes are for the dowels.

Success! gave it some more serious umph and it broke free. Thank you gentlemen for your advice. I thought it better to ask than risk more trouble. Cheers.

The best utility tool ever made is a standard hive tool. Mann lake supply in Minnesota sells a good strong one.. Spring steel, can sharpen edges to razor sharp. Best pry bar ever for this type problem. Great gasket scraper also. I cant be without 2 of them.
