Red ones are Big ends 8 in total to which the con rods are attached. And are nuts.

Blue are mains 6 in total which clamp the crankshaft to the cylinder block. And are Bolts.

As you can see the mains are bigger in size.

Would we need to tighten mains if we didn’t loosen them when we were taking the pistons?

Picked up this 880 implematic at the start of December. It's very original, some period mods, only two owners before myself.

Doesn't need much doing, rewiring it, water pump and the front axle needs rebuilding after a life loading dung

 

[Netherfield]

If I knew they'd been torqued correctly last time then no, If I didn't know who did them last time then yes.

Having said that while the tractors in the state it's in I'd be wanting to see the condition of the bearing shells anyway.

not my tractor but one of what may have been to come, it is a genuine picture of a tractor labelled the Z model
apparently under the drivers seat is a full power shift gearbox
not sure where the driver stored the ladder to get on

 

[Courier]

Never short of parts books or maintenance manuals, he would just ring publication and have them sent to his office, he got me the piston tool and a valve seat cutter, but they were well used and being replaced by new ones and would have only ended in the scrap bin.

Only other useful items were crankshafts, and these were also destined for the scrap bin because the journals had been damaged, 10thou regrind cured that but of course you couldn't send new tractors out with them fitted, although a large amount of 3 cylinder engines went out with liners fitted, someone had bored the block wrongly on a night shift operation, reckoned they couldn't afford scrap all those blocks, they were sent out to a former employee who now worked for himself locally.

Almost eyerybody who worked in O block (Engines) who had a Ford or British Leyland car had a spare alternator 'borrowed' from the factory, all they had to do was drop one and damage the end case and it was declared scrap, then if you needed to fit it to your car just swap the old cover over.

Sounds nearly as bad as the IH Doncaster Wheatley Hall Road plant where complete wheels and tyres would disappear into the canal/river at the back of the plant and float over to the other bank for retrieval…

I dont think it was a great sucess. I think the power train made it extremley sluggish

Where some of the tractors where parked was at the side of farmland, bloke used to come in to the local, 'anything you want let me know' toplinks, link arms and various pins were were easy prey for him, batteries and silencers were not fitted until they left the place. Never took him up on it, and he did get caught one night by the security guards, although empty handed.

When they moved the parts dept to Batley, lots of parts were ferried across from Meltham, one of the drivers was bragging he could get any part anybody wanted, someone asked him for a suspension seat, but nothing came of it.

Some of the errors made by purchasing, tropical radiators made for hot countries, parts got asked for 20 for spares, somebody ordered 200 from Serck's, 180 ended up in a local scrapyard, security man went with them to see the wrecking ball squash them.

Parts sent a memo to Father in law wanting crankshafts for discontinued models, he set a team on to work weekends on overtime to machine them, they sat in parts for months and then got returned for scrapping.

One chap came in at weekend to repair a machine in the engine dept, security let him park his car right at the side of the machine, he left Sat afternoon and came back Sunday to finish the job, he didn't turn up at his place of employment on Monday, his vehicle had come off the road and crashed down a banking side, the boot of his car was filled with alternators.

Could anyone here message the admins on the dbtc forum and ask them to approve my registration (same username). Could use some specialist knowledge and I don't do Facebook

What a shame that David Brown wasted all his money building Aston Martins
They were so far ahead of the field

996 number 2 in for some engine work

This one thinks it's a Ford and has water in the oil. Also looks like it's been running on coal.
@Selectamatic you'll be glad to see I took the pipes off before the head this time..

 

[Boohoo]

Engine work turned into an engine swap.

Both pictures of the same tractor?
How many engines has it had as I would think a spin on oil filter would be rare on a non Q cab model

Same tractor. 1976 pre Q cab 996 that had a replacement engine out of a very late 996 or early 1390 before I bought it less than 18 months ago. That engine had been bored and lined but started putting water in the oil and we found metal in the oil too. Pulled the engine apart and found big ends and mains scored, the thrust washers chewed and the crank ruined. Bought a replacement 1976 engine so back to original type oil filter. It'll get a remanufactured clutch too in the hope we never have to split it again.

Well it has a David Brown engine in it, does it qualify?
