Re: 990 project

Welcome, looks like a good project, best trick I have is look up the part number on the caseih parts website. Then put that number in your favorite web browser.
Get the proper owners manual and plan on changing all the fluids and filters.

Re: Replacing DB885 Axle Housing Seals

On the 900 those 2 holes are threaded. A simple special tool is bolted to those holes. 2 more threaded holes in the bar are used to pull that part strait out. It came out easy. There are 2 seals inside that part. I assume the 885 is the same. I may have a diagram or some photos someplace if you like...

Re: David Brown 995

This picture picture looks a lot more like a $2000 tractor than the first one! In my area the old DB tractors don't sell very fast so you could probably negotiate a better price especially if it needs any work to be functional.

Re: 900 front axle surprise

Thanks for the comments, I used 1/8" 7018 rods because they were handy, in hindsight I should have bought some smaller rods or dragged out the mig welder. There was no center hole in the end of the ************ axel but I think I could of mounted the stub axle in the 4 jaw chuck and supported the ax...

Re: 900 front axle surprise

I decided to try welding and thought I would post some photos even tho this is a tractor forum and not machine shop forum. I ground off the old threads and added weld to one side then re-drilled the cross holes thru the weld and repeated on the other side. Built some fixtures to mount on the milling...

Re: Engine rebuild

I think there are a list of things you should carefully look at before and as the engine is being disassembled to try to see what problems are there. Here are a few ideas, I am sure there are others more knowledgeable than me that can add to it. Already mentioned, compression test, make note of RPM,...

Re: 900 front axle surprise

If I had a large enough lathe, I would build up the threaded section with weld, mount the stub axle between centers, turn down the welded area to the correct diameter and rethread it. I have done this type of repair on other parts. I think it would be possible to do it on a milling machine with a bo...

Re: 900 front axle surprise

I do like the idea of building up the damaged thread area with weld and cutting new threads, My lathe is a little too small so I am not sure how I would get it back to round after welding. Have to think about that some more.

Re: 900 front axle surprise

Thanks for the replies, I had not thought about legality. I was thinking of a 2 inch piece of high strength threaded rod screwed into the end of the stub axle and held with permanent grade locktite. I guess some other smaller bolt or pin to hold it in place would be added insurance? I am thinking th...

900 front axle surprise

You never know what you will find on an old tractor. Here the axle nut has been welded to the stub axle. There is a stack of washers under the nut but still several mm of gap. The roller bearings were OK on this side but shot on the other side. As expected the threads on the stub axle are shot. When...

Re: 990 hard to start and excessive white smoke while running

Check fuel delivery (check at a bleed screw on the injection pump when cranking ). Check injection timing. Checking bleed screw when cranking is an interesting idea, I saw a pretty good stream come out from the lower bleed screw on the injection pump, is this all pressure from the lift pump or some...

Re: 1594 Hydra starting problems - smoke but no fire.

My 990 implematic has an ether plug on the intake manifold, it is about 1" dia plastic plug with a bit of felt. The instructions say add ether to the felt and replace. I have found (from someone on this forum years ago), that directing a propane blowtorch into this opening helps with starting better...

Re: 1594 Hydra starting problems - smoke but no fire.

GeoffDeal, I found exactly the same thing, some careful measurements showed that the pump stroke was way less with the engine running than using the hand prime. You can actually feel this by putting some pressure on the hand pump lever as the engine is cranking. You can feel it moving a small amount...

Re: 1594 Hydra starting problems - smoke but no fire.

Is there any accepted way to check that the lift pump and filters are working properly, supplying the proper pressure? For example on fuel injection cars there is a test point where you attach a pressure gauge to the common rail. I wonder measuring pressure at the bleed fitting at the filter output ...
