d950-a-t possibly d950 already toasted?:eek: Did you check the here? located on left front engine frame rail. ALso check the right side frame rail. A lot of parts available for this engine or a reman engine is about $1800 if unsure if you can rebuild it.

May not ship to United States.
Even if they did, shipping of engine from Brisbane, Australia plus shipping of core to Brisbane, Australia would be kind of expensive. o_O

Yes D950's are worth rebuilding.
You really can't easily swap it out for any other motor series.

There is no definitive answer to lettering behind the number, and I've never had it give me an issue as far as parts or a rebuild goes.


You will have to strip the motor down and send it to a machine shop to have the sleeves installed and bored, the rest can be done without any real special tools.
Here is one rebuild kit.

Unique to the B20 is the hydraulic pump is driven in front by the crankshaft. Not sure if the block is special. Had one for 23 years and they are tough and ever so handy on the farm. Failed injector hurt the engine and couldn’t find a replacement within budget. Sold it for 25% of I bought it for and upgraded to B26.
