You should be able to spin the PTO with the engine off

Definitely not the safest thing to do!

If you are pretty mechanical, it isn't terrible, but the seat and the rear transmission cover to inspect the PTO. I believe that the clutch is removed by removing the top PTO shaft from the rear, but the service manual shows that the rear end has to be separated from the transmission. Not sure...

And, do you have rocks?

Does it ever stop? Sounds like a hydraulic “wet clutch” PTO and either the solenoid valve that the switch controls is stuck or not hooked up. Also, the PTO brake is worn, the brake actuator is bad or the hydraulic system for the PTO is leaking by internally, but this usually causes the PTO...

You probably got the timing retarded too much. Or you put in incorrect plugs. Did you try and time it again?

The screws missing are not critical as the lug nuts and wheel hold the drum on. To replace the axle seal, the axle will have to be removed and disassembled.

Thanks Sportsman762 for responding as someone with MF experience should have answered sooner, but you have responded and that is great. I was working on my phone this morning and didn't have an answer until just now too. The link here is the pump with the notes that FordnMassey needs to...

Replacement with one to another shouldn’t be a problem, but I will investigate to see differences for rebuilding

Probably not real difficult, but it will sure get them to muscle up. You might ask this question on Allis Chalmers Forum: https://www.allischalmers.com/forum/forums.html

It probably has glow plugs, do they work? Is the fuel system and fuel clean? Do the injectors atomize fuel?

May have to heat the fitting after draining the coolant if PB Blaster or similar doesn’t work.

Pretty sure that one just pulls out. The ones that have to be pushed on have another internal snap ring in the barrel and I don't see any in the parts book

Copied parts book including both Maki 525 and 546.

The Maki 546 and 525 are odd as I thought Antonio Carraro tractors were just 4wd, equal sized tired, articulated tractors. Something new all the time! Stuart B and ptsg

Screw them all.....? But are they tightening the flywheel against the crank. It doesn't look like it

Basically, are the bolts too long and going all the way to the bottom of the hole, stopping before tightening the flywheel

Hard to say, but with that play, I would think it would throw it out of balance. In any case, there shouldn't be any play between the two. Are the bolts bottoming out before they can tighten the flywheel to the crank?

I would certainly figure a method to tighten the fit. It could be what contributed to the broken crank.

Okay, different crankshaft explains a little more. A pin is good, but you still need a tight fit flywheel to crank with or without a pin. Is it the bolts are bottoming out in the crank that is preventing the looseness?

I started to say that, but the parts book doesn't show one. It would help, but there looks like there is clearance between flywheel and crank

It should be tight. Are your bolts original? There is a shim, 187886M1 that can be used if the bolts are bottoming or hanging on the bolt shoulder. You could also trim the bolt length, but you need to determine what is causing this

Probably an updated/standardized industry size since your excavator was made

Ford did have the 756C backhoe subframe mounted available for the TC21, 6’ dig depth. As previously stated, it would probably not be cost effective and may be slow. I also agree that mounting a backhoe on that tractor is not a great choice as the rear end housing is aluminum and could break...

.22 mag or .357 snake shot load. If not readily available, I use a shovel carefully placed to sever the head.

Yes they did. The sales manager at Coastal Tractor in Salinas was a Howard Rotavator rep prior to that position. I can remember that model that you have (I have an E2 I believe) and the big M models that would till behind 100+ hp tractors. Heavy, heavy duty.

Wow, that’s an oldie!

First off, that is a ZF axle from Germany, not Carraro from Italy. There are aftermarket parts for both manufacturers for many of the hard parts, but few steering kits for Carraro and practically none for ZF. Anyway, the Deere 2555 uses an APL325 axle and the seal kit is AL70934, about $140 from...

Also, tractor fluid has additives for friction materials.

WAC (World Agritech Corp.) markets the Sicma mower in addition to the Caroni. World Agritech Corp (WAC) - IM - DN Equipment Parts link: Sicma:Finish Mower:All Sicma Finish Mowers:All Sicma Finish Mower Parts

They are time consuming to remove, but other than removing the steering wheel, which can be difficult even with the right puller, it might be worth the time to clean and seal with something like the following...

Could be the original valve, I assume it is electrically activated, or circuit has closed. If we know what it is you’re working with, we can armchair diagnose for you

Oh gosh, you are correct. I have been under the weather and was thinking of a TN, not TC!

You're a good son! Enjoy the time you have with your dad. Glad we could help.

The starter sounds like it is weak if you jumped the starter spade terminal. More correct, the solenoid may be weak to the point that the solenoid engages the starter gear, but not enough to make contact with the internal motor connection in the solenoid. Or, the contact points are burned enough...

The rear weights are 105# each. Generally, 4 weights is a good counterbalance.

Not knowing that unit, I would guess about 8 gallons

First, let’s talk about the numbers. 2708 lb. Operating weight is how much the machine weighs. Lift capacity is 760 lb. what the loader can lift…no more. And that may be figured at the bucket pivot pins, but may be figured 12-24” from the pivot pin. Tipping load is figured by lifting the loader...

Welcome to TBN. Regarding your 1973 instrument pane. Yes, and???

Glad it was a fairly easy fix and that it is working again

The button on the left side of the dash is for the thermostart manifold heater. Push it in when you are cranking, not before. BUT, it sounds like something else is going on. Does it smoke at all when you try to start? Do you have the throttle open all the way?

Does the relief open slightly when you pull the sector handle all the way back or just in general lifting the 3 pt?

Not really a time on the engine or the calendar, but being they are both 20+ years old, from a preventative maintenance perspective, it wouldn’t be a bad idea to do so. It beats waiting for water to start weeping from the seal in the middle of whatever you doing. You can also grab the fan (when...

There is no top or bottom to that bearing. The bearing washer goes in first, followed by the bearing, followed by another washer and finally the retaining ring. The bearing may be greasable, but the housing is for a non-greasable bearing. If it is a greasable housing and has a hole in the...

I am not sure about the draft other than there is a linkage problem under the 3pt top cover. The leaking down of the hitch is probably the lift cylinder seal is worn out. Both require removing the top cover to repair.

Is this a Case IH 885 or a David Brown Case 885? Whatever version, the PTO shaft may come out the back of the tractor and it is being held by a bearing from coming out the front.

I agree that engineers don’t necessarily have to see the fruits of their labor after it has been in the field, nor do they have to disassemble their works of art. The safety switch mandates are different for every series and size of tractor. The smaller the tractor, ie: lawn tractor, the more...

Masseys are strange in that respect. Their hydraulic system is not normal. Glad you figured it out

Welcome to TBN. #25 boot in the diagram attached is kind of pricey, but Messicks or any New Holland dealer can get it for you. https://www.messicks.com/commoncatalog?vendor=nh&modelId=148605 How many weights do you need?

No need for more pictures. The parts are pretty common. The front axle may be a Dana 44 or 60 axle from some of the research I have done. I like the story and what you have done. Let us know how we can help. This is a great story
