According to what I can see the original engine for a 7MB-prefix D7G is a 3306 of 10Z prefix.
However here's the kicker. There are over 100 different arrangements of 3306 machine engine alone,and that's not counting industrial and genset applications.
If you have a specific 10Z engine in mind to go into the tractor post the Serial Number here, also post the Serial Number of the engine that's in it now.
D7G ser # is 7MB02959. original engine ser # is 1TF03652. I am proposing to fit serial # 10Z10185 cat 3306. What changes do i need to make for it to go straight in ? and at the 200hp setting ?
Interesting.
(As you can see Nige,) SIS shows 7MB2959 as a D7G 1997 build, but my old skool serial number index shows 1984 build with a 44V engine. What little information there is gives us a transmission serial number of 7KA7650, but the only option for this tranny in a 7MB is for a series 2 5000-up serial number.
1TF comes up as a 3306 vehicular engine from 1987 and both tractor and engine were made in Indonesia.
7MB should be similar a 65V or 92V, so I'm going to take a stab at 4N4506 being the correct engine arr for this machine, and say that the 1TF isn't the correct engine.
Your 2 possible replacements are no problem but I'm having trouble tracking down the details of the original engine S/N 1TF03652. Is there an Engine Arrangement Part Number listed on the Serial Number plate ..?
It looks like 10Z10185 is also a 1W0543 arr from a D7G, so if your original engine is arr#1W0543, the 10Z should drop straight in.
Have you seen a plate on either engine that makes you think they are different horsepowers? I can only see 3 test specs for that arr# and they are all around the 200hp mark.
Have you looked in the cab for the original serial # plate riveted in there? It may be a bit battered, but if you can read it it will tell you the serial and arr # of the engine the machine was originallly shipped with.
At first glance, no. This list shows what has to be changed. It looks a lot, but sometimes the difference between say the front gear groups for example may only be a couple of upgraded bolts. If you were serious about using this particular engine, you would have to sit down with the two parts books and go through the listed groups and see what the differences were.
