[jaf302]

Just found this site and thought maybe someone can help. Have a MF135 with an ad152 perkins. Bought it as a basket case, engine out and all apart.Have experience rebuilding before this project. Now the problem,engine has new crank, all bearing clearances checked. New oil pump. oil pressure gauge very erratic when running.removed oil pan and riged up pressureoil feed to engine. No big leaks untill I turned the engine with a wrench. Large leak in front cover. Removed cover, leak occurs when idler gear lube hole lines up with hole on the boss the gear rides on. No serial number on block,nadda,zip. was ther a change up in the blocks,hub and gear? or is a restrictor plug missing? (whew) sorry for the long story but does anybody have any ideas? thanks in advance Paul Jaffer

Have you got any pictures?? Is the hole threaded like there could have been a restrictor at one time. Have you looked at a parts diagram of the engine to see what if any parts are missing??

Thanks Mattman, No pictures, and no parts books for the engine. I believe the block or short block was changed before I got the tractor because of the missing serial number on the engine. Tractor is in storage right now and all together. I wonder if there was a changeup inthe front of the block in later years. My tractor is very early, I forgert the year right now,but it is the firsr or second year they made them. Does anybody know where I can call to get a good breakdown of the engine thru the years? Does anybody here have any info on the differences thru the years on this engine? Thanks Paul Jaffer

I have a 1964 MF-135 diesel that I bought in Jul06 and have been pecking away at a refurbishment ever since. It's a standard 135 set up to squat low for mowing and discing work in the olive orchards around here.

I checked my info that I got from Big Dean Austin, an expert on MF tractors of that vintage. Unfortunately his AOL website is gone and Dean isn't in the best of health.

However, I do have Big Dean's servicing CD. Here's what he says about leaks in the front of the engine.

Don't know if this will help. Let me know if you need more info and I'll try to dig some up.

My 135 has an oil leak somewhere in the front of the engine. I guess I'll have to drop the oil pan to troubleshoot the problem. Not looking forward to that job since that "pan" is a steel casting that weighs a ton.

Hey jaf if you have got a bit of time up your sleeve i can ask my boss when he gets back to work next week (he gets to go on holidays) he started his apprenticeship on te20 and has worked on massey ever since so he is pretty knowledgable on these old bangers

can't healp with the leak.. bt ont he eratic gauge.. could be a cheap non compensated gauge.. a restrictor will help that..

Soundguy,Thanks but the gauge is showing the problem, every time the hole in the idler gear lines up with the hole in the hub that it rides on the oil pressure drops off to almost nothing. As soon as they don't line up oil pressure is normal. Flusher, VERY nice job on the old girl. I guess what I need is someone with a set of Perkins parts books with the different years to see if there is some mis-matched parts on the front of this engine. thanks Paul

I have all sorts of Perkins manuals up to and including 1984 serial #'s. Not sure if I can help, but willing to try. The Perkins AD3-152 is almost a family member with me! Had this'n since new in '71!

Finaly got a little time before work to catch up here. Farmwithjunk, if you have part books for the different years I need to see if there is different part numbers for different years when it comes to the gear train and idler hub.My best guess is that a replacement short block was fitted(or empty block) before I got this tractor. Then they used the orignial gear train and that is when the problem started. When I got the tractor the rod bearings were wiped out and the crankshaft was .070 thousands out of round. One new rod and a new crank, pistons and sleeves and valve job later and here I am Thanks Paul

I'll spend a few minutes going through the parts book later on today and get back with you on what I find.
