1555 diesel hard to start

bv · Feb 11, 2014

Are the 1555 diesels harder to start than the other Oliver diesels and if so why?

My dads 1555 was hard to start in winter.We used to put tractor and spreader in back row of dairy barn.It wouldn't start today and it has 1650 gas engine now.Its just been cold,it ran fine just the other day.I have had a super 88, 1650, 1950T,WHITE 2-70,American 60.Best starting was 1950T and the American 60.Hope that helps.

never had a 1555 but knew a guy who did his started easy every time i was around, id assume there direct injection like the others of that time they start fine its indirect inj. that needs the can of starting fluid , we had a 1655 diesel that would start fine even in cold weather just have good batterys & heat it with button , my 1855 diesel will start at 32 deg. with out heating it at all & if you have a gas engine that wont start in the cold its just worn out , oliver's gas tractors where one of the easiest starting engine ive ever had

If I recall correctly a 1555 was a Lanova or pre-combustion diesel and won't start as well as a good direct injection.

However, with good rings and the head set up correctly they start pretty well.

I don't recommend ether. That is about the easiest motor to make knock that I have personally seen. The one I fixed had 5 out of 6 top rings broken.

Its not wore out yet . Going to get more gas after work today.Its starts after only few revolutions and a little choke. They had lavonia injection ,back in early 80,s rebuilt 1555 engine and head was rebuilt. It started better but both my 1555 and 1650 with lavonia injection started hard.We also had block heaters on all diesels and 1950T Started best in winter.Greg

Same situation/combustion chamber as 77/770 & 88/880. If the valves are set incorrectly and the valve seats are sunk too far into the head it wont start well. New seats with valves basically flush with the head, rings, pistons, sleeves tight and in good shape along with a gear reduction starter and it will fire right off as well as any new tractor.

On the 770's 1550-1555's I been doing I think it helps to set the pressure up on the injectors. I always test them for spray an not to drip but I also crank the pressure up to 1900#. It seems to help as long as the injection pump is up to snuff also. I think it atomizes the fuel better an they seem to start pretty good! But the cylinder head is the biggest problem. In the old days everyone would do a quickly valve job an after the years of a couple of those the valves get way too far in the head an you loose all your compression, especially for a good start!
Good luck

Remember they also had a larger higher speed starter.
