I have a '48 Pony, developed a knocking at the rear of the engine, replaced a bad clutch and throw out bearing but the knock remains. Engine runs good so I assumed it was ok, not sure now.
This started this after I foolishly tried to bump start it, she ran great before this.
Does anyone have info on the Continental Model N62, L-Head engine or an idea what my grief may be? Thanks!
Randy

Hey Ken,Alan... Appreciate the help, I think I'll pull the engine again and have another look around and hopefully it won't be anything too bad!
Alan, I will check that flywheel, that is the right area!
Bump start is some ass#$%e popping the clutch on a Pony to start her and breaking it, won't happen twice!!!

For those who haven't tried it yet but are forced to in the future....

Better to hand crank it over, they start easily even with a pretty dead baterry. Barring that, I think the 'safest' way to 'bump start' is not a bump start and popping the clutch at all...I have done this once with no problem or damage at all.... Put it in 3rd gear (HIGHEST gear), leave the clutch alone, chain on the front of it somewhere (I had my front plow), ease out the slack in the chain, and pull SLOWLY - when she starts up, push the clutch in so you don't rear-end the puller. Gentle way to do it...

Hope this saves someone from some damage on down the line, but pull or bump starting anything risks damage, so even this use with great caution - cheaper to own a handcrank.

For the original question, if it doesnt go away, look to see if you bent the shaft in the torque tube or have something out of alignment that is causing a wobble. Could also be something as simple as a pilot bushing problem (did you replace it when you did the clutch?)

Good Luck... -Ken (in NY)

Did your oil presure change any? Are you sure your flywheel's tight? Also what in the heck is a bump start?

Randy: Be sure your noise is in the engine before you rebuild it. Try shorting out one cylinder at a time while running & knocking to see if you can tell if any one cyl. causes the noise. Try pushing the clutch pedal down also because the drive shaft from the clutch to the transmission could be rattling. If you find that the noise is NOT in the engine you could run it under a light load for a little while to see if it disappears. After having my clutch out the driveshaft rattled for a while then stopped. Good Luck, Ken
