As I get time and money to go through my new to me MF390 I have been doing the little routine maintenance items. This week was the fuel filter. The old one was leaking a little and I felt I just needed to change it. So I did. After I changed it I used the primer lever on the lift pump to bleed...

Now that the 390 has been around for a little bit I have found out a few things about it. First off it is still smoking badly due to blowby. Bummer but not the end of creation. It runs really well and has been pulling a 15 foot cut Woods Batwing mower around this week probably about 10 hours so...

Well as a friend and I have stepped up our hay operations substantially this year (went from 8 acres to 58) it became time to add a remote to the 135. I bought the tisco kit HV4211 with the ts300 isolator valve and the fender mounted control valve. Installation was very simple. During...

Saturday while picking up and moving a rake from the John Deere dealer for a friend I noticed they had a Massey 390 parked in the used tractor section of their yard. It is a 4wd with a Massey 838 loader. Looks pretty rough but that usually means it might be in my price range. If this is too...

I am in the process of rebuilding the wobble box on my 489 haybine. It's complete but I am lacking the torque specs for the castle nuts on the wobble shaft. Anyone know what it's supposed to be? Also wondering how to set the side to side adjustment shims for the drive yoke. Any particular...

I have the opportunity to purchase a 2135 industrial that's equipped as a forklift. It has a deck and all the controls and basically runs around backwards in relation to a normal tractor. It will reach 21 ft high and has a side shift as well. I've been using it around my farm since last Friday...

Well now that I've gotten the steering sorted out on my tractor (finally) I am looking to add a remote for my haybine. I know there are remotes available I just want to make sure I am getting the right one. Since my tractor is an Orchard model is has the 165 rear axle. What I don't know is...

Has anyone here ever worked on a 135 orchard power steering assembly? I am trying to figure out why mine doesn't have check ball assemblies in the steering valve. It has machined cylindrical spacers with a center hole to replace the check ball assemblies. There is no recess in them for the check...

I will first confess that the extent of my hydraulic knowledge is centered around rotary gear pumps used in the chemical industry and the things I've learned fooling with my MF 135 tractors' steering system. Let me first apologize for the length of this post but it's been a long saga that leads...

Well most of you probably saw my other thread on this subject. I hope I'm not muddying things up with this one but it seems my issues might be outside of the scope of the other thread. After really looking things over I have determined that I am getting a pressure spike in valve spool assembly...

Today while bush hogging around my place the hydraulic valve on my power steering started gushing fluid. At the same instant my steering wheel got loose and the retaining nut came off. I still have mechanical steering albeit with a wobbly steering wheel. My thought is that the retaining nut let...

Well having spent some time on my tractor now (about 6 hours) I have noticed that it turns significantly sharper to the left than the right. It seems the two steering cylinders are not the same and the right one is binding on itself when pulled in all the way. I need to measure them and see what...

Today I just made a deal for a 135 Orchard. The previous owner had it listed as a 70' model but admitted that he wasn't exactly sure. It's a 3 cylinder perkins gas engine. The tires are good and it has some 21.5" wide turf tires on it. It also came with a rear blade. The good; Runs really...

Hello all. First I want say I am really enjoying this site. Been reading it for about a week now and have been researching plenty on here for opinions and good/bad issues with all kinds of tractors. On to my questions. I have 49 acres. 28 of which are cleared and pasture established on about 15...
