Question, are the o-rings that came with the new section the same size as the ones used between the old sections?
The reason I ask is, I can buy 3469149201 KA10 Intersection seal kit from White House, Hy-Power or Tidyco but I'm having trouble locating 3459149004 Unit 10 Intersection seal kit (pre October 1986) except from a Parker Distributor here in the US $14.80 each
White House told me their;
V8093 KONTAK UNIT 10 SPOOL KIT is Parker 3459149003 $3.38520 USD
V8091 KA10 INTERSECTION SEAL KIT is Parker 3469149201 $9.10780 USD
V8031 POPPET VALVE TYPE UNIT 10 PRE 1986 is Parker 3459149006 $22.6970 USD
V8031 should be a Parker 3469149112 ALDCV-KIT
V8015 KA10 MAIN RELIEF VALVE (CARTRIDGE) is Parker 3459002001 $31.7886 USD
I received a quote from a Parker Distributor here in the US for the 3459002001 Externally Adjustable Main Relief Valve $285.44 That same valve V8015 KA10 MAIN RELIEF VALVE (CARTRIDGE) is $31.7886 USD from White House.
As a matter of fact, I received a quote from that Parker Distributor for all the seal kits for my Kontak Unit 10 Valve and their prices are all more than double what it would cost me to buy from White House including shipping.
3459149003 Spool Seal Kit $24.50
3469149112 Check Valve Kit $43.97
Tidyco (http://www.tidyco.co.uk) has some prices that are lower than White House.
Sorry for the delay, I only just saw this post.
My BH 108 Owners manual has the date November 1, 1986 printed on the front cover. I'm not certain if that means my backhoe was manufactured after Oct 1986 or just the manual was. However I can tell you this... I ordered a new pre-1986 Load Check Valve from White House and the valve they sent me (which was clearly marked pre-1986 on the package) would not fit my valve. I would assume that means my bh is not pre-1986.
Having said that... the O-rings that came with the new Unit10 valve I received from White House were the same as the O-rings used in my valve but keep in mind that my Owner's Manual is dated November 1, 1986.
I already had the O-ring kits for connecting the valve segments together so I didn't need to order those kits from Parker or White House. For reasons that escape me, the end cap O-ring kit is different from the valve segment kits... why?
The larger O-ring (I think about 1") I needed for the end cap I found on e-Bay for 5 bucks (package of 100). I also bought two O-Ring assortment packs from Harbor Freight, Item# 67554 (US) and Item# 67580 (metric). Each package contains almost 400 O-rings of various standard sizes. I got them for about 10 bucks each during one of Harbor Freights never ending special sales events.
