    535 frame hydraulic plug leaking

    Today was only the second time I started my 535 LTB (successor and nearly identical to 4500) and noticed a new leak coming from the [i:1b5b33f833]driver's side[/i:1b5b33f833] frame hydraulic plug. I'm pretty sure it wasn't leaking last year, but there is a decent size oil puddle where it was...

    755 backhoe Blown a hose

    There's probably a cheaper option. You can get a replacement hose online, for a little over $60. My local shop wanted at least $25 more, so it will depend on how quickly you need it and how many hoses you decide to change. The part number for the six big/main hoses is D8NND558EA (aka LBP 291016).

    Elementary lube questions - Ford 535

    I tried all of the easy answers, but it wasn't going to work. There was no movement at all. I did end up drilling it. Most of the shavings seemed to come out of the hole, rather than in, and I tried to clean those up as much as possible. I ended with a 15/64 bit to try to avoid enlarging the...

    Elementary lube questions - Ford 535

    I really appreciate the helpful advice. Regarding the press-in zerk, after better exploration, I now realize that there is something just below the outer surface. It appears to be metal and has a hole in the center. I suspect this is a broken-off fitting. How do I remove it? Am I going to...

    Elementary lube questions - Ford 535

    Regarding my 1977 Ford 535: 1. On my left spindle (?), there is a grease fitting on the top and the bottom. On the right, there is no fitting on the bottom. There's a hole, but it doesn't feel like it's threaded. I tried to screw in a Zerk fitting, but there was nothing for it to screw...

    Parking brake not holding on 535

    No enclosed cab, just an OROPS. It does have the T handle. I looked for a parts diagram on the NH website and couldn't find one for this. I'll crawl underneath and see if I can figure out where to add the washers you suggested. Thanks.

    Parking brake not holding on 535

    The parking brake on my 535 ([u:24ca0f564e]very[/u:24ca0f564e] similar to 4500) is not holding well on even a slight incline. It feels like there's less tension on the handle than when I got the tractor three years ago. The actual brakes still seem to work well and it doesn't feel like I'm...

    750 Backhoe hose replacement

    Myron, I certainly agree that working on the hydraulic hoses is easier with the backhoe off, but do you have any secrets for getting the quick couplers connected/disconnected. Mine are a nightmare. Even after letting the thing sit overnight, moving all of the levers back and forth to try to...

    750 Backhoe hose replacement

    Myron, you're absolutely correct that rounding the corners is better. It's on my "to do" list, you know, the one that you never get around to. I downloaded the parts diagram from New Holland and color-coded the six primary backhoe lines. This might help somebody who gets them mixed up...

    750 Backhoe hose replacement

    There's a similar thread with photos [u:6f917072ff]here[/u:6f917072ff]. I did this last year and was too cheap to replace my boom hoses while I was changing the others. Guess what I'm doing this week? I bought the $28 flare nut wrench. It's unused because it's still too fat for most of the...

    535 thermostat or temperature sender problem?

    Thanks very much for the helpful replies. I'm glad to know that I'm not risking blowing a head gasket from a closed thermostat. As far as I can tell, it's a 1977. I don't get near a dealer very often, but eventually I'll get there. But my luck will be that the CNH part does the same...

    535 thermostat or temperature sender problem?

    When I bought my 535 two years ago, the temperature gauge wasn't working. I recently installed a block heater, changed the radiator hoses, changed the coolant, and replaced the temperature sender unit. The connector tab had broken off. The sender I got from the tractor dealer 75 miles away...

    Power steering turns wheels left (535)

    Sean in PA, thanks for your help again. I finally found the adjusting turnbuckle buried at the bottom of the front compartment. I heard too many stories as a kid of farmers having an arm torn off by a PTO, so I was nervous about the spinning hydraulic pump linkage. I tried making the...

    Removal of 755 backhoe attachment from 4500

    Those "quick connects" are anything but quick. They were a nightmare to get apart and a nightmare to get back together. It takes two people pushing and pulling at the same time in a space designed for none. It makes me never want to take my backhoe off again. In an effort to fix a few small...

    Time to add some winter heaters to 4500.

    It is CNH Part #86590140 and they can be had for less than $40. I just installed one on my 535 which is very similar to the 4500 (seems to be its successor). I used a very large punch (about 1/2" flat round end) and tapped the edge of the freeze plug three or four times until it just swung in...

    How to operate 535 3-point hitch (Gannon setup)?

    I finally was able to test things out again. It appears that the hydraulic lift system is working. It was probably working all along, but I was just too impatient and didn't realize how slowly and silently the pistons move. I haven't tried moving the flow control (missing knob) yet to see...

    How to operate 535 3-point hitch (Gannon setup)?

    Oh...OH! What a dope I am. :oops: For some reason, I assumed that the 3-point hitch pump must be in the rear axle. So every time someone mentioned an engine-mounted pump, I [i:3f301b5c67]assumed[/i:3f301b5c67] they were referring to the pump in the front that powers the loader and backhoe...
