Members,

I have another thread going but I believe I may have figured out some new information since that thread started. First off I noticed a leak on my SCV which has 3 valves. At first I believe the leak to be around the couplings coming into the SCV but after further cleaning and inspection it is no doubt coming from where the housing mates between the 2 valves, the 3rd valve, and the tractor. Attached are pictures of what I am talking about. Where the yellow lines I have drawn are the leak areas. There is not a gasket between these housings but rather tubes and o rings internally. Would you advise buying new o rings and tubes or just the seal kit (re45959)which is o rings I am assuming, I cannot find any description of what part 45959 exactly comes with ? Per Jdparts.com I will need 6 tubes @25.00 so they are getting expensive quick. Also would it be recommended during reassembly to put some formagasket or something similar when mating the valves together? Also is a parts diagram showing tubes which are 3 & 4. Thanks for any help you can give. Chase

I would think that the tubes should not need replacement, and I'd just get a whole o ring assortment that JD should have along with their other little misc "kit's" like roll pins, grease zerks, etc. I'd skip trying any type of sealant and leave that for a later option. You might have a talk with one of the mechanics or service writer while your in there about your leaks.

Ditto on what Rusty stated about no sealant or tubes required BUT I'd be hesitant to substitute any o-ring as o-ring are manufactured from different type materials & hardness. Below is the spec's listed by JD for o-ring(key 10).
