To add information.


The male fitting is 20mm X1.5, and have a exterior cone end about 30


The female end is the same 20mm x1.5 . It have a shoulder sleeves to help support the flared end of the hard line.


It look very much like an British pipe tread but with the cone reverse.

Good day.


I'm refurbishing a 81 Belarus 420. In the process of that, I'm changing a few things.
I'm trying to find what obscure hydraulic fitting they used on the hard line.


Where I'm from there is not much "non standard" fitting.
But I can order.


I'm looking for the connections that tie hard line to hard like. It the same as the banjo on the hydraulic valve.


Can anyone help

MT3-82 with a driving steer axle. The nut that holds the pitman arm to the bottom of the sector shaft for the steering gear has come loose. The threaded end of the sector shaft is buggered up, but looks to be salvage-able. The driving steer axle is close enough to keep the nut captured. I am unsure if the smart move is to pull the pins and drop the steer axle down for access with the tractor supported... -or- unhook everything from the power steering group and pull it out.

  I favor dropping the axle for access. The pins appear to be hollow and threaded, for pulling.

My question... the pins have the part number 52-2301058-A according to the parts information I have. In the parts book they are called "swing axle". Does anyone know with certainty what size bolt and correct thread pitch these pins have?? Is there a puller group made for pulling these pins?? they appear to go into blind holes from both ends.
  Thank you for any information!!

MTZ Tractors - Old Models (Belarus) / Re: 822 electrical problems

My 825 has a hood decal stating 822.  I replaced the ignition switch and the interlock relay.  The grounding switch was disconnected at the time.  I smelled something burning and the series/parallel switch was smoking...   I have'nt figured out what caused this.........  The wiring is really a pain.  The wires all look the same color.  I have not really found a wiring diagram that fits the tractor.  The one on page A5-9E appears to be the closest....   Has anyone had experience with the wiring on these??   I have a spare series/[arallel switch.  If this does not fix it then I am going to have to rewire it to 24V start with the gauges running on 12V.  I have a 24v self exciting alternator.  I really don't want to go to all that work right now as I will have to remove the loader to do all that work.  Hanging over the side of the loader is not fun..

I have changed the keyed starter switch on the dash but the starer will not crank.  When started, the indicator light on the left of the dash goes out.  The s tarter does not engage after the tractor has run up to speed as it did before.  However, the ammeter is not indicating the alternator is  charging.  The schematic I have shows a 50amp fuse labeled PB50 or PV50 the location is stated as front dashboard, but I have not found one there yet.  Does anyone have any experience??

MTZ Tractors - Old Models (Belarus) / 822 electrical problems
« Last post by damengineer on March 09, 2020, 10:44:48 AM »
My 822 would not start, the starter would not engage.  24V switch would acturate but no starter.  One of hte screws that holds the solenoid onto the starter had vibrated out and the solenoid case was out of alignment.  However, after getting it all together I started up and drove about 300 ft and the starter engaged.  I staopped and restarted it and after it ran about 15 seconds the starter again engaged.  I finally had to quit.  It appears the interlock relay is bad.  I have ordered both relays in the circuit and another ignition switch as my switch is frozen and I had connected a switch to the 24v switch to actuate the starter.  Perhaps the ignition switch is stuck in start position and causing the problem.  If replacement does not work, then complete rewiring is in order...

I have chained a post to the tracks of a dozer to get it unstuck.  When it got to the end of the tracks, it broke the chain, so use an old chain..    You can also chain a post to the outside of the tire so it will dig in the ground as it comes around.  works well if the tires are wider than the fenders.  Also can chain a short piece of log to the outside of the tire and stop just before it hits the fender...

MTZ Tractors - Old Models (Belarus) / Re: Belarus/MTZ hydraulic pump upgrade
« Last post by damengineer on March 09, 2020, 10:32:36 AM »
Talked to Ray and he also said the pump was a left hand rotation.  However I found this one on Ebay that is for the MTZ 80 & 82 which I believe is the same tractor as my 822 & 8345.  I believe this pump can be run either direction.   I am going to try it. 
here is the link...https://www.ebay.com/itm/NSH-50YZ-3L-NSH50U3-BELARUS-HYDRAULIC-PUMP/142606509566
