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.

Re: Engine rebuild

@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...

Re: Stripping down for painting

Id get a shorter fuse too as theres only a small contact area with the long fuse fitted. Looks like youve got a 30mm fuse in a 25mm fuse carrier??

Re: Selectamatic linkage bounce

Ok. If you think you are drawing air in, you could put a hose onto the rear camels hump tapping and run some oil into a clean bucket to see if theres air coming through with the oil. Dont let the gearbox oil level get too low before pouring the oil back in!!

880 selectamatic history

Does anyone know if theres a development/modification history of the 880 in existance as a single document? Ive got a list of around 50 changes/milestones that Ive come across but wondered if there was ever any sort of official log??

Re: Selectamatic linkage bounce

I also think I’m drawing in air on suction side( this improves on steep climb ) due to oil level probably. Not sure if Ive missed something, but if the oil level is low its probably best to fill to the top mark on the dip stick. If the oil is anything other than clean and clear probably best to cha...

Re: DB885 Starting Difficulties

Just for peace-of-mind, I haven't had the battery charger on it for 3 weeks. It's also stood idle for 2-3 days @ a time and started right up. Even on sub-20 degree mornings. A new battery is on the agenda for next week. Why a new battery? Battery sounds fine. Sounds like you may have had an issue a...
