Cat 12 Grader Brake Line

King, living way up there you need to have a Double Flaring Tool and a Bender. Then get a 25 foot roll of every size tube and matching flare nuts.
Later Bob

bob - the King is looking for a rubber hose .. a bender and a roll of Bundy tube ain't going to do him much good, there .. 😄

King - You wouldn't believe this .. but I haven't got anything as modern as a 99E parts catalog .. so I looked up the old 9K catalog .. got the P/N .. and then checked the NPR, just on a hunch that hose never changed in nearly 30 years .. and I was right!! ..

The hose P/N is 4B8761 .. and if you keep a spare on hand, it will fit nearly every rigid frame Cat grader built, that's fitted with brakes, from 1938 to the early 1970's .. 😮

KoO Well I searched that CAT number on the Napa web site and no good, but I did run it on the CAT part number search and crossed it over to a Napa number UP 4900 here is it's description.

Brake Hose End Type : 7/16" - 20 & 7/16" - 24 Internal.
Brake Hose Gasket Part # : 1243
Brake Hose Length : 17.688"
Caution Statement : Do Not Use w/ Petroleum-Based Fluids - Designed Only For Use w/ DOT Approved Silicone- Or Glycol-Based Brake Fluids.

Hope this helps. Here is a pic.

HI king I have a 99e 4491-up parts manual and the line r.h. is 4d6957 and the L.h.is 4d6958

KoO I tried to cross both numbers that Gemdozer posted to Napa and both are no go, and they do not interchange to any other numbers on the Cat interchange.

Gemdozer - I'm not too sure on where you got those 2 P/No's from, Hector .. but the 4B8761 hose is listed in the Cat NPR, as fitting 12E graders 99E1 to 99E14170.

I Found These Number In Page 86b Parts Manual 99e Forme34780 And In Page 86 You Can Have Too The Part Number 2f5495 Rh And 4d4192 Lh
Tube Ass.

thansk guys, the telephones are up and working and i got a hold of buddy barry 1200 kms in the south and he will swing by napa and pick up 2 brake lines. when he returns to the great white north is when we will find out if they fit. if not i'll have new brake hoses for my monster truck, LOL.

thansk

King - I'm pretty sure you'll be right with that NAPA hose that jmvmopar did a good job of finding.
I am still at a loss, at to where the other P/N hoses, that Hector found, fit.
I don't have any 99E parts books, not even on fiche, so I can't see what he has found.
They may have been some kind of hose variations that Cat tried sometime, to save a dollar .. but they then found they didn't work, and went back to the original.
