I found a OMI for your 6A blade for your D6B on eBay for a low price.

I did find a reference a few weeks back regarding the addition of the 0 but not the 2 regarding serial conversion. I did not know it applied to parts numbers as well.

 

you misunderstood. what i meant was you might have to add one or more zeros to get a six character p/n. i wasnt real clear with that point. some of the older part numbers have been superseed to other items too. a google search can be helpful here. if the cat parts data base has the info it will show some of the superseeded parts and list the new part number

craig your correct paypal isnt secure either.

a solution is a prepaid debit card if they get the details they only have that info and access to that money.

I was being facetious with my comments about PayPal and other credit cards. Security measures have greatly improved over the years. I was actually venting my frustration at people being afraid to use cards. I shouldn't have done that.
The most foolproof way to pay is by a CASHIERS CHECK that can be purchased at any bank. The cashiers check is paid through the BANK'S account and doesn't have any of the purchaser's info on it. The cashiers check is imprinted with the exact amount desired so there is no "unused balance" wasted as is the case with prepaid cards.
The prepaid credit cards can be a victim of scams when purchased from an open display.

the ones im refering to are reloadable.

Greetings all,

Last comment on Paypal... they will refund with little or no hassle. I'll not bore you on the supposedly guaranteed funds of a cashiers check. All points are well taken. Craig, while I am happy to join ACMOC please don't hold your breath waiting for a cashiers check. It's all I can do to squeeze time out of the day to address all the irons I have in the fire as it is. Unfortunately this won't be one of my higher priorities and I rarely get to the bank.

Thank you Craig for the manual on the blade. I have ordered it and it is on it's way. Can a hydraulic tilt arm be affixed to this style blade? I will be using the dozer to grade new roads and I have this vision of having to get on and off and back on the dozer many times through the day with the current manual variant.

I understand now tranzkid88 what you are saying on the part number.

Again, thank you both.

Hi, hdokes.
Your 6A blade would require to hydraulic tilt cylinders working opposite directions to be 'technically correct'. How-wevver, some people have only fitted one tilt cylinder and gotten some tilt action, I'm guessing with pretty worn blade angle/tilt braces.

One cylinder works on a straight or semi-U blade very well, thank you, but an angle blade is a vastly different geometry. One side would be fighting against the other.

Just my 0.02.

Hi there Deas Plant, the blade I have is a straight blade, I assume indicative of the 6A you are referring to.  I am pleased to hear that it may be possible to affix a hydraulic tilt cylinder even to one side. Now to determine where I might find one. 
 

Hi, hdokes.
If you have a straight blade, one ram is all you need but make sure it is a good one. There can be a LOTTTT of loading placed on a tilt cylinder under certain conditions.

Just my 0.02.

6a is the angle blade. 6s is the straight blade.
