FEL Sudden drop under load ( update)

Forum Members,
Thanks for the info of possible solutions on the FEL sudden drop N syndrome. Removed the shifter lever cover and ran the 8N this morning and found fluid gushing all over. First thought it was the piston, but found a large 1/2 by 1/2 inch section of gasket suspended in the mechanism of the top cover. I am going to replace it this morning.
Question is, is there something better than picture framing mat board to use as a gasket? The mat board is quite tough. Any thoughts are welcome.

Because of the high pressure involved, I would use a ready made gasket (avail here at YT and other places). No gasket goop on that gasket either.
 
As H-Cooke said get the correct gasket or your going ot be doing it again very soon and it is not fun to do that job. Most any good NH/Ford dealer should have that gasket on hand. Even an O'Reilly's should be able to order you one or this site. I said a dealer first because you can get that today maybe
 
HC,
Checked the parts department and found the gasket set. What am I going to do with all that mat board stored in the shop?:):) Thought about inserting a modified copper grommet into the oil port opening of the gasket. Just a thought.
Have one more theory. My new theory is to wait for a lot of forum input before theorizing.

nless the metal surfaces are damaged, the paper gasket has been the working solution to sealing those parts for over 70 years...no new "invention" needed now.

I'm thinking that grommet is a good recipe for a cracked top cover. It takes very little unevenness on the clamping surfaces to crack a flat casting like that.

hat little "ckick" when you torque down on a cast iron part is a real downer! :cry:
 
Correct gasket and NO type of gasket crude. Trying to fix what has worked for decades does not work with this area of this type/modal of tractor
 
I've done a half doz of these. Just the paper gasket and no sealer. Use some 7/16" bolts with the heads cut off to hold the gasket in place while lowering the top cover into place. I also use a small wedge between the main draft spring and the rear end to hold the cover up while I re-position the control arm.
 
dry paper oe style gasket.. nothing else.

the only other possible mod I would do is have the cover cut for an oring that then sandwiched down onto the deck.. I have seen a fergy with a deck cut oring boss.. etc.

still.. I've done plenty N with paper gasket and have never had to go back in as long as the deck and cover were clean and smooth there.

remember if you put a metal crush gasket around the port.. the cover will not set true, making the outside of the cover be at a different angle, and thus encourage blow out.

the engineers covered this by 1939.. no need to reinvent it.

Sounds like you have had some personal experience along thes lines. Hope it was something cheap like a thermostat housing :roll:
