12e grader

Most likely a replacement engine out of something else.......can't tell you what. The later 3304/3306 etc was the first engine series that had a separate/different engine serial number from the machines they were installed in.

The 99E is an oil clutch machine so its unlikely to need replacement.

Still was the old knuckle buster manual control box. Wear gloves! You really want to run this thing and see that the circle turn mechanism and lift on each side works well enough. You can force the blade down and pick the front wheels off the ground if the lift clutches are good.

Been several threads about old graders here lately. Deas has contributed a lot of pointers on them.

Can anybody tell me what engine this is off of serial #.

96F is the 14D series grader, 1964.

Can anybody tell me what engine this is off of serial #.

99E0551 is a 1959 12E model with D333a engine
96F1407 is a 1964 14D model with D333Ta engine

You'd have to get up into the early 70's to get into the 3306's or the late 60's to get the D333c's with 4-3/4" bores.

Any one have any ideas on the numbers stamped under the serial plate in the pics. It sounds like it has a different engine from original. I'm wondering if these stamps might indicate a rebuild.
Thanks for info.

I don't recognize those stamped numbers as being anything meaningful other than 1964 production is s/n 1101 to 1590. May be some engine parts interchanged????

So the d333 from 1964 era still doesn't have the best reputation or were they fixed by then.
Old Magnet it stands to reason your previous post about early engine failures as to why this grader has a different engine than it came with.

Improvements were made throughout D330/333a production to where they became a pretty good engine at the D330/333C's with the best becoming the 3304/3306's but by then most of the changes were with bolt on items. Production requirements for those early engines have long since passed and are certainly adequate for the occasional use applications provided parts are still available and the operator is aware of wear limitations, operating temperatures, cooling requirements etc. in other words can baby their units.
