Thank you very much for the complement. The engine looks very well put together I just used the tank and dash board off the combine your set up will serve you well for years.

Whatever you do, do not, try and run your engine at less than 1,500 RPM it will not like it. These engines were never designed to run lower.
How did u connect the db gearbox?I have the option of 540 or 1000 rpm on the gearbox. I’m sure @fredf said they had gearbox troubles when using theirs in the 540 gear but no issues running in 1000rpm with the engine running at about 1200rpm
Was going to try the first load on 540 anyway just to make sure we have enough power.
Here’s a photo I took before the guard went on. It’s a HRC coupling held on with taper locks - the combine shaft already had a key way the right size, and I cut down the DB input shaft and had a key way machined into it.How did u connect the db gearbox?
I think mine might have been cheaper!!Here’s a photo I took before the guard went on. It’s a HRC coupling held on with taper locks - the combine shaft already had a key way the right size, and I cut down the DB input shaft and had a key way machined into it.
You can also see the new blanking plate I made up for the gearbox, it’s bolted on where the gearbox would originally have been bolted on to the back end of the tractor. It’s got a filling plug and a level plug for the oil, and an oil seal where the shaft goes through. View attachment 909442

And your labour£££££??Probably, this ending up costing just over £1000 including all the bits for the engine rebuild. Don’t think there would have been much change from that by the time I got yours home and modified to 540rpm...

I used to run a gardner lorry rngine at about 1200 rpm on dryer no probA non turbo 6.354 has max torque at 1300rpm, turbo at 1600rpm, with the DB PTO you'd need 1800rpm on the engine to get 540 in the low setting and 1080 rpm to get it if using the high setting.
is the power curve not according to set yup and that will be related to the source of the engine. We used them for irrigating and it was reckoned that you ideally wanted to be running around 1800-2000 RPMA non turbo 6.354 has max torque at 1300rpm, turbo at 1600rpm, with the DB PTO you'd need 1800rpm on the engine to get 540 in the low setting and 1080 rpm to get it if using the high setting.
But that was a right engine and were designed to run at such speeds in industrial use, in the truck in my avatar you could let the revs get down like you say and still it would recover where most engines would have stalled.I used to run a gardner lorry rngine at about 1200 rpm on dryer no prob

Friend bought a really big V8 not sure the source and geared it to run at 1200 thinking it would save fuel but all it did was wreck itself after a few hundred hours. Mind you these second hand engines often had already had one hard life.
I did source an engine from a MF combine which was 25 years old and had only 700 hours on in that time and I know it was genuine, but could not get over somebody buying a new combine to run it for 30 hours a year!

GrantMo you got my story the wrong way we had trouble with the gearbox at 1000 rpm and no bother in 540rpm. Your setup looks good I hope it serves you well.
