[DeTomaso] Seals

[Stephen Nelson]

Previously I wrote (7/3/14 - see below) that I have found seals for the
original clutch slave cylinder on 5332.  While the seals from Sealco were
the right inner and outer diameter, they were made of a stiff material which
would not stretch around the piston for installation.  So, back to the
drawing board.  Searched the web for seals that matched the 5/8 inch ID, and
1 inch OD, made out of something that would stretch appropriately.  Also
hoped to find seals that would fill the roughly ¼ inch slot (0.28 inch) in
the pistons.  No luck.  But I did find seals that matched the inner and
outer diameters but were slightly thinner (3/16 inch) at
https://www.herculesus.com/ .   The same outfit had backing rings that were
0.070 inch thick to help fill up the slot.  The attached pictures show my
piston with both an original seal and a new seal with backing ring.  

 

The backing rings are pretty stiff – make good backing rings.  I did cut the
ring so it could slip into the slot – fits in nicely.

 

Part numbers are:

 

Seal – HRU 18-0.62-18 (SKU 13978) - $1.89 each

Backing Ring – 870-48 (SKU 119238) – Come in pack of 10 - $6.375

 

Not real sure one needs the backing ring, but it does lie in nicely.

 

Hope this helps someone wanting to use an original slave cylinder.

Stephen,

 

Did this seal fit the stock piston?  If so can you give us the sealco part

number?

Got to the point I needed seals for the clutch slave cylinder on 5332.

Talked to Dennis at my favorite supplier - Panty Perf - he doesn't carry.

So, tried a couple of seal outfits here in Portland.  Unanimous opinion -

people don't carry seals any more, but one shop did manage to find a 1 inch

piston that would go in, and all I would have to do is turn a different cup

on the end that the rod goes into.

 

 

So, being from OKC - I called Sealco in OKC.  http://www.sealcompany.com/

God bless Sealco.  I used to live in OKC - needed any kind of seal they had

it.  And yup, like $3.30 each - no problem.

 

 

 

Youse guys need seals - Call Sealco!
