Re: Purchased a Cropmaster - Have a few questions

I think that if you want to retain the original reg num on the 880 you have to show some official record linking the reg num to the tractor. If the green log book is showing the tractor serial number and the original reg then I beleive that should be sufficient to get a new record set up at DVLA, an...

Re: 780 selectamatic loader spool challenge...

By the photos the return hoses come back to the spool valve, any return should dump back to a suitable connection to the gearbox this applies to using a double acting valve on a single acting cylinder or cylinders. The same applies when using a single cylinder on remote double acting plug ins the s...

Re: 880A Selectamatic information request

On my 880 the 2 tubes run from under the back of the seat then follow the front of the PTO housing round until they get level with the underneath of the ram shaft bearing housing. At this point they run horizontal out towards the mudguards and finish there. The brackets are held in place by a couple...

Re: 780 selectamatic loader spool challenge...

When you have the quadrant lever in the select position you have to hold it against the spring to get full pressure to external equipment such as your loader. If youre not pulling the lever fully back and holding it against the spring you may not be getting enough pressure to get the rams to move. T...

Re: 780 selectamatic loader spool challenge...

Its definitely a super loader with a powered bucket tip. The spool block looks new, certainly compared to the loader- did the guy you got it from say he had it working?

Re: Oil prerssure

The OP asked where is the bypass valve and as far as I know, as cobbadog said, the bypass valve is in the filter housing, item 22 in the linked parts drawing.

Re: 990 project

Try ebay for secondhand parts but watch prices for a while to know what the going rate is. Unless youve got a reliable service history, Id start by changing all fluids and filters and flushing first if the original fluid looks really neglected. Some tinsel round the top of the cab would look good to...

Re: DB780 Hydraulic Pump Outlet Diameter.

The outlet on the spare 880 pump I have is 20.6mm or 13/16 inch. There was a change of pump manufacturer on the 880 in Feb 67, but I think the old and new pumps were interchangeable so there wouldnt gave been a change in outlet bore??

Re: Engine rebuild

Theres already at least 3 other topics on what appears to be this same tractor, one titled blow back, one titled fuel injectors and one titled 996 starting problems. Might be worth resurrecting the "996 starting problem" topic as this one is starting to cover exactly what has already been said!!

If I have caused any confusion or troubles I'm sorry and I apologize.
I dont think you caused any confusion as it was quite clear your suggestions were generic and intended to be nothing but helpful. No need to be sorry, or to apologise.

Re: Engine rebuild

Old tractor engines are relatively simple compared to modern engines so if you work methodically you should be able to strip and rebuild an engine with the aid of a manual and this forum. A bit of practice on an old 4 stroke engine will help with confidence and understanding of how bits fit together...

Re: Engine rebuild

Forgot to say that if you do want to strip the engine but arent to confident, you could get an old car engine from a scrap yard and strip that to get a feel for whats inside an engine. Youll probably struggle to find one, but an old push rod engine would be ideal.

@patrick. You had a previous post on poor starting and there was never any conclusive findings but vague suggestions from your trusted mechanic about a variety of possible causes. Did you ever do a compression test To check engine condition? Ive just had a quick look at the original thread and your ...

Re: Selectamatic linkage bounce

Hi guys, fitted a new suction pipe o ring and re assembled, the hydraulics were instantly sorted , all the symptoms are sorted except the linkage is slow to drop on high revs? Is this typical of an old 880 or do I need to have a look at that ? Many thanks to all who helped and as ollek said ( any a...
