    Default Cat D6B Info please

    Hello, Im new to the site. I recently purchased a Caterpillar D6B off a man that purchased it off my grandfather in the 1970s. My grandfather had many dozers over the years D2, D6 9U,D6B, D6C, couple of D8H's, and a D8K. But sadly over the years he sold them off long before i was born. He passed away a few years ago. So i took it upon myself to try and find one of his old dozers and make an attempt to restore it. I stumbled upon his old D6B by speaking to a few old fellas that knew him. The tractor is very rough but I only paid the price of scrap for it. I was able to fire up the pony motor but could not get the main engine to crank. Pulled the plug from the base pan and all that came out was black sludge, followed by antifreeze. I believe the head is split open due to the exhaust being cracked off at the manifold. If anyone would be able to give me info on the dozer the serial number is 44A 8232. Ill post a few pics.
    Thanks Stephen

    Still has the can on the exhaust pipe, so may not be so bad. Maybe head gasket, PC chamber or sleeve. Hope the water in the crankcase is not from a cracked head. D333 heads usually are hard to find. You won't know until you get into it though.

    We rebuilt one in a 12E grader that had a wrist pin fail after the oil pump locked up. That took a new block where the connecting rod beat the casting up! It had been sitting out in the weather in central Alabama for several years without the head and the remaining cylinders were STUCK! Got to try several tricks I have learned on here before it came loose.

    Good luck!

    Oh, where are you? Will help to recommend sources.
    D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time

    So I posted this thread about 3 years ago. I finally went and took this D6B home a couple of weeks ago. I'm currently in the process of trying to get this dozer running but I know that the head is cracked. I'm wondering if a D333 engine is the only engine that will work in this tractor or if another engine will bolt up and be operational. I'm in Newfoundland Canada and parts and engines for these old tractors are very hard to find around here.

    I would get the casting number off of yours to make sure it's the right one.

    Jump on that head regardless - you can always sell it later since they are hard to find
    Cheers,

    Don't know where they get that number.
    Original head for 44A8232 is a 8M0694
    Late version is a 5S1884, casting #2S2970

    Something's fishy there somewhere...that crank sure ain't out of a 6-cyl. engine...
