Re-use original gasket or not?? (Pics attached)

Hey guys. Would you re-use this original water pump paper gasket when reassembling the tractor? It is from a 1968 Farmall 140 tractor (4 cal gas) and is the original gasket. It's intact and not torn but does have a little peeling. Not much. I just hate to break up a complete engine gasket set for this one.

It would probably be OK with a little sealer smeared on it, but why not pick up some gasket material and make a new one?
 
In a pinch, it COULD be reused with a REASONABLE application of silicone gasket sealer.

It would be EASY to make one from sheet gasket material.

On the other hand, you can still get it from FIAT for some $2, part # 375745R2.

If you are not in a great rush, any dealer should be able to get it for you in a couple of days on a stock order with no shipping charge.
 
Spray a little bit of that red tack gasket adhesive on it. Not like it's a 200 horsepower tractor.
 
It's a (paper) gasket! cut a new one. Poster paper would be a close thickness. If you like black gaskets color the poster paper with a marker the color you like. I have used poster paper for gaskets for year and never had one fail. I have used copy paper for thin paper gaskets.
Paper is paper!

Dick, I have made my own gaskets from cardboard for years as well. However, plain cardboard does not stand up well to water. I have removed the remains of cardboard gaskets from cooling systems that were reduced to mush. I strongly recommend the use of gasket material from an autoparts vendor.
 
(quoted from post at 06:36:30 03/24/17) It may be fine for now but you don't know how long it would be before it fails. I would prefer to use a new one.
thanks for the input guys. I ended up buying a big roll of similar gasket material for $5. Will cut a new one.
 
Black RTV silicone by itself works just fine,garanteed not to leak.
Clean both mating surfaces with brakeclean before coating one with the the silicone,..don't overdue...a little will do a lot. for best result let it dry for 12 hours before exposing to water and oil.
 
I bought individual pump and thermostat housing gaskets for an M not to long back. And that
was from a case/IH dealer. Check into it. That gasket may be acquired without buying a set.
Its hard to tell from the photos weather I would re-use that one. If any chunks of it
pealed off and stuck to the pump or block, I would not re-use it.
I would also not try to re-use it in conjunction with any kind of silicone. It will likely
leak over time if you do. I was a mechanic for over 4 years, and in my experience, I never
seen a gasket silicone combination that didn't end up leaking. I had to replace a lot of
gaskets from do it theirselfers who would end up bringing the leak to me to do it and fix
it right. And all I did was replace the gasket with a new one, only without the silicone.
 
I agree with the comments about not using silicon! Best gasket dressing I've found is HYLOMAR Universal
Blue. It was developed for Rolls Royce. Looks like Permatex is packaging it again for sale in the US.
The last time I needed some I went into my stupid NAPA store, asked the manager if they had it or could get
it, guy looked up their webpage said it sounded like some good stuff then ignored me till I walked out a
minute or two later. Worst auto parts store EVER!

Good job RTR! I agree also with avoiding the RTV silicone. It has its places, but I have found when taking things apart a few years after using it that moisture works in between the silicone and any steel or cast iron, and it is no longer serving any purpose.

he key to get RTV to work flawlessly is to clean the mating surfaces well. RTV silicone is used extensively factory in the automotive industry as oil pan and valve cover etc gaskets. I've used it for many years and never had nothing leak ever.This stuff sticks and seals so well once it is cured(10-12 hrs) that the parts can be hard to separate again.
