It would seem I bought a red headed step child here. Even going to the local Massey dealer they could not give me any detailed information. Serial no. not listed. I need to purchase shop and parts manuals but need to know if they will apply. I believe it is a mid 70's MF40 Industrial. It has a MF32 Loader S/N L810010847 with dual bucket cylinders, 3 point hitch arms, with all controls. 152UA Perkins, Original S/N 389469D per Owners manual. S/N on block is 152UA131161D. Std clutched xmsn with a lever on the left for forward and reverse. Looks like the previous owners bought a short block, no rust on the unpainted block but head is yellow. I have an issue with compression gases pressurizing the cooling system, I hope it is just a head gasket. I bought the gasket but do not know the torque for the head. Any help would be greatly appreciated
 
head bolt torque is 60 ft. pounds
if you go to the link agco I supplied you can scroll down past the dealer log on and click were it says
guest user click the box that says view books
on the next page type 40 into model and in the all brand box change it for Massey
if you want to check parts for the loader put 32 in model as its listed as a seperate unit from the
base tractor as they were add ones
this will at least get you correct part numbers
BTW this site sells parts for MF 40's too
agco
 
According to the data I have the MF40 you have should have disk brakes. The engine should either a Perkins AD3.152 diesel, or AG3.152 gas engine. Going by the 9A 207276 serial number it was a 1974 year model. The 1975 year model serial number started out with 9A 207681, and up (last year of the MF40 industrial).
 
Thanks for the information, I really appreciate it. I am new to this site so thanks for the quick response. This is a great tractor and I intend to restore it. For it's size it is quite powerful. Much better than the 9N I grew up with. It came with a set of forks and a bucket but had the a combination platform/receiver hitch mounted on the back. It was most likely used in the orchards around here.
 
I found not only was the head gasket blown, but #2 liner is cracked at the top between #2 and #3 cyl. It runs down about 1/4". I don't think it is to the water jacket yet. I have about a days worth the work I have to get done so I am going to put it back together and hope it lasts. That being said it looks like major overhaul time. Any thought on who would be the best ones to go through for overhaul kits? I am very skeptical about buying short or long blocks as the warranty usually is very short. Does anyone know the average number of hours you get from a 152 3 cyl. diesel?
 
The Perkins is a dry sleeve block so it's probably only the sleeve is cracked. If the engine has good oil pressure, and the rear main seal is not leaking you can do a "in tractor" (in frame) rebuild. You would only need to remove the oil pan to take the pistons, and sleeves out. As to how long the engine lasts my brother has a 1965 MF150 with the 3.152 diesel. He bought the tractor used in 1975, and the only thing he has done to this day to the engine besides replacing the filters, oil, and coolant is replace the lift pump, thermostat, and a leaking head gasket. So the Perkins 3.152 engines are super reliable (for 51 years in my brothers case) if you take good are of it.
 
I am only into this tractor including purchase price about $800. I have so far bought the tractor, repack kit for the 2 bucket cyls, loader valve repack kit, head gasket and a new battery. I am a equipment mech by trade so the rebuild should be just parts. This one is worth restoring I think. Thx again all you guys for the info
 
I was really fortunate. Fully restored I am hoping to be in around 4K. I have never worked with the Perkins before. Mostly bigger CAT and Isuzu engines. I do love this old tractor though, should serve me the rest of my life anyway. She is a bit beat up but made from good steel. I will post some pictures sometime soon. have a great day.
 
I know. If you want a backhoe that is mechanically the same quality as CAT without the fancy cab. Buy a JCB. same machine. They both come from the same factory. Same goes for Hitachi/John Deere when it comes to excavators. My professional preference is Komatsu. at least you own your entire machine. :)
 
I've run Cat, JCB, Hitachi, Komatsu, etc way back when I was a equipment operator. The Komatsu are pretty good machines, if I can't have a Cat dozer, Komatsu dozers are just as good. The only excavator (or other types of equipment) I hate are John Deere, especially their excavators!
 
I am an Operating Engineer. Switched over from aerospace sometime back. I have worked with all of them. My job is to keep the vendors from coming to visit. Once we went global it all changed, different strategies by different companies. Just depends where you want to spend your money. Cheap buy ins usually means they withhold more information so they make it up on service calls. This is especially truth when it comes to software.
