Re: Spun bearing on 990

I do not have much experience rebuilding engines but would assume you will need a new connecting rod. I think you should be able to measure the crankshaft diameter to see if it is within spec (from service manual). Might be a good idea to pull the pistons out and try to get an idea of overall cost b...

Re: Hydraulic take off on db 25

I flushed out the transmission in my late 900 (pre implematic) with diesel. I had found the gauze disconnected and filled with water and crud. I think I have had just about every hydrauliuc component apart and cleaned (3ph valves, ram cylinder and TCU valve and pump). I don't know if diesel was the ...

900 seat and mudguard

I have started working on seat and mudguard. I have more time than money at this point so am trying to repair and reuse as many parts as possible. I know the seat support system is not correct but am not too sure what it is supposed to look like. I am repairing the battery box and am using a photo f...

Re: Cropmaster steering

As you turn the wheel back and forth look closely for any vertical movement in the steering wheel. This would indicate a problem with the spherical ball bearing at the top of the steering column. You may or may not see any sideways wobble. If all is tight at the top it must be something at the botto...

Re: Cropmaster engine and tractor numbers

I think the 900 engine is same or similar to Cropmaster, it certainly has little in common with my 990 implematic. Can you tell me what the "back side plate" is? Is this the cover over the pushrods? There is a flat machined surface below the rear pushrod cover on my 900, I have cleaned this area but...

Re: Cropmaster engine and tractor numbers

Geoff, any chance you could provide a photo of the location? I am afraid I am not following your description. I assume it must be someplace you can see without disassembling the tractor? The only number I have ever found on my 900 tractor is 030 on the engine. Thanks

Re: Referb injectors

I understand the need to have the bores clean but wonder if a very light coat of grease will keep rust off the injector or bore?

Re: Gear Lever Rubber Boots

I replaced the ones on my late 900, they would not stay in place on the transmission, I ended up cleaning up the casting a little with an angle grinder to make a better lip, and installing them with silicone gasket sealer. They have held up good since then. The boots came from davidbrownparts

Re: Break pedal removal.

I have a 990 that had one of the brake pedals seized to the shaft many years ago, I ended up cutting part of the right foot rest to get the pedal off, Unfortunately I don't remember all the details but I did get a fairly good looking weld when putting it back together that you can still see if you l...

Re: 880 Selectamatic poor starting

I agree with Rid54, Check for good flow from bleed screws with engine cranking, Others more knowledgeable than me have said a rebuilt engine needs to be broken in with some hard work. I would certainty do a compression test and service injectors before rebuilding injection pump. Not sure about where...

Re: Interchangeability of parts

On a similar issue with 900 which may be same axle as your 30, The correct Timken tapered wheel bearing, 19283X with 19138X cost more than the entire tractor. Some measuring found National 30207 for $ 18 from Rock Auto, they fit OK, are slightly wider than the Timken and have a 14 degree cone instea...

Re: king pins

In my 900 late manual there is a spec for king pin end float of only 0.002" to 0.006" or 0.05 to 0.15 mm. All the parts had worn on mine so I fit new washers of custom thickness to get a snug fit. I think some float is not a big problem because the weight of the tractor will always be pushing down a...

Re: 885 Loader Removal

It seems like the lift ram orientation is also determined which end is removed when the loader is removed. On my 990 the cylinder end is down and it stays with the tractor when removing the bucket. On the 885 photo it looks like the cylinder stays with the loader. The hydraulic tubing connects to th...

Re: 900 front axle surprise

On to the new parts and reassembly. One side of tractor had the correct Timken tapered wheel bearing, 19283X with 19138X . The other side had SNR 30207. I could not find the Timken bearings for a suitable price locally so bought National 30207 for $ 18 from Rock Auto, they fit OK, are slightly wider...
