Pic from work today if anyone's interested lol. I don't do much work like this these days as I'm normally playing with wires or every 3rd week on my late shift doing brake down call outs. It's a short engine change on a cf75 tipper. The things been putting diesel in the oil. All avenues have been explored now and the customer is a little pissed lol. So Daf technical ok'ed a new engine as it must be the block at fault as the main fuel gallery and 6 pumping units sit in the block. It's a big old job .

Good old DAF's, you get many gearbox issues? Our local TNT man is always moaning like fuck about his lorry

ajamesc

yeah lol I've rebuilt loads they use zf box's the small 5 and 6 speed ones are famous for nose cone bearings. Done a few eaton ones but to be fair a lot is syncro wear due to drivers

creator

Other than the size of the engines are they much harder/easier to work on and change than a car? Wished id of gone trucks instead of cars the money is so much better

ajamesc

As a hole easier as the bits are a lot bigger and not so fiddelly lol. It can be hard work as bits are heavy but some systems like braking suspension and emissions control are a fair bit more involved than cars.

More pics more pics.......... Did you take the engine out the top I take it.


We had a few lf.s in our fleet and they have been spot on.

gingeRS

Which engine is it? Euro 4 mx or trx? I know the 10 and 13 litre daf engines inside and out, I've never seen a fuel pump gallery crack though

YOREVOL

we run isbe cummins in our daf's, we've got 7 and only 2 engine failures in 6years 650000 km. drivers abuse them as well, the throttle pedal is an on/off switch to them.

ajamesc

Its a euro 5 mx and it won't be cracked it will be a porous block that's faulty some wear around the fuel gallery.

ajamesc

Yeah lifted out from the side with the fork lift and the boom. I've done almost every job there is to do on an lf lol from engine diff and gearbox re builds to changing most parts on the thing! Done loads of Pistons and block re bores with liners fitted. Wear they have got hot and driven to the point they pick up. Also changed the crank in one once that had only done about 300km it spun a shell lol

are they wet liners bud ? all mine bar one are and there a bit of piss no messing just 6 piston and liner packs and job done

if they are wet do they suffer with counterbore wear issues ? all ours have over the years with rebuild after rebuild and eventually needed machineing and a 30 thou shim putting in to bring it back to spec

mind you id guess some of our cats are knocking on for 60000 hours though on the chassis/casings

ajamesc

LF engines that I'm talking about in the above comment have no liners but we fit liners to them after a piston has picked up and marked the bore so the block can be re used. But I have done one that got plus size Pistons in all 6 pots after a re bore that was a good job as it was a bare block strip down. I've also fitted one over size piston in a few times lol makes no difference really!
The engine above is wet liners

ajamesc

the above engine dose suffer from liner lift as the block rots and lifts the liner it catches people out as the think its the head gasket! You have to measure the liner height. If they have lifted you pull the liner out then there's a new liner with a larger rim at the top and you cut the block with a special tool and fit the new liner so it sits at the correct height

weve had the same mate, last one I did was a liner that had a 6 thou discrepancy on the flange after 7000 hours ? I put 1 piston and liner in and a new 30 thou counterbore shim and its done about 700 hours now touch wood still all good out working in good health.

Daf's are shit. Oil in the water. Crack the blocks the flywheel housin crack. And the wiring is shit. And the price of part are well over the top

ajamesc

Lol I work on them every day and see them and good reliable trucks. Every make has its faults Man Volvo Scania they all do! Only ever seen a flywheel housing need replacing due to driver abuse letting the clutch go to a point it took the casing out as well never seen a block crack? In the 14 years I've been doing it this is the only engine ive changed due to a block at fault! Most engines are changed due to driver abuse.

karl mcghee

i like big engines easy to work on nothing gets in your way

am currently rebuilding a transit after melted pistons

ajamesc

We have a van shop as we do fiat ford and ldv a few sprinters as well. I stay out of there lol

gingeRS

Good to see an old eup engine

Daf have gone common rail for euro 6

ajamesc

yep the big engine is now commen rail but has 2 two unit pumps supplying it. Euro 6 is very complicated and will take some getting used too lol the emissions system is very involved

steveboyslim

Looks like a fair bit of work, how many hours ?
One of the chaps on corsasport works for Audi did a 40+ hour job on an Audi R8 V10 in just over 10 minutes see Looks like HGV work is easier.

Steve

ajamesc

Daf give you 16 hours! I'm 12 in and the engine is back in the chassis. Got a fair bit left to do lol. But warranty work like this is very tight on time. They are more generous with other jobs like brake changes and servicing so you make up hours to cover jobs Like this

vroooom ptssssh

Are you actually for real or do you genuinly think he done that job in just over 10 minutes?

Cool pics matey. The engine is massive.

More like 10 hours. Even thats good going.

steveboyslim

40 hours work, I do not think he works that fast, I was just making the point that some jobs on certain cars involve a lot of work and that working on commercial vehicles may look daunting when in fact it is just that the parts are much larger.

Steve

ajamesc

The parts may be larger but mark my words on a 8 legger its a struggle to get the box out and it had a large pto plus the engine is very tight in the chassis and a struggle to get out with that hi ab and walk way. That's a very involved job lol
