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...

Re: 990 3 way take off valve

Its been awhile but I think the 3 way valve is pretty simple. I had mine off and apart years ago. I ended up making some new knobs and threaded shafts. I used some cheep orings when assembling and had leaks, I purchased the correct part number parts from caseIH, and all is good now. I do not know if...

Re: Voltage Stabiliser - Posotive or Negative Earth (885)

I don't know about the 885 but on some of the older mechanical voltage regulators, the output voltage is adjustable, I was able to get an old lucas one working with the help of a DB Lucas technical report I got off the web someplace. Unfortunately it is too large to post here.

Re: Replacing DB885 Axle Housing Seals

Scottusa, What is the name of the local fastener shop that has the BSF bolts? I wonder if they might have a branch near me. The closest I have found is brittishfasteners.com which is several hundred miles so its mail order when I need one or make my own, the BSF tap and die set has come in handy for...

Re: Replacing DB885 Axle Housing Seals

I got the replacement shoes and the long and short copper rivets from davidbrownparts.com. Easy to replace. I could not find a supplier in the US.

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...
