My mate, he had his Series 60 in getting work done at Detroit dealer in Sydney, they replaced the front cam gear, went for the road test and it fell OFF! The valves of the engine were hammered into the head so tight, they could not be removed, and they had to give him a new complete cylinder head LOL
Friend wanted me to overhaul his 60 series and I told him to take it to Frieghtliner and pay their price and get a dealer warranty good at any dealer..They overhauled it and yes it was expensive but it burned oil shortly after the overhaul.Frieghtliner said there was a recall on the liner kits and overhauled it again at no charge. Don't think they would help an independent shop in that case...just laugh at you
Volvo D13 engine breaks the inlet roller if not set valve gap correctly. The roller ends up bouncing on the cam at certain rpm and it cracks roller and takes out the cam lobe.
I agree with most of what you said. However the compressor doesn't depend or require boosted air. Driving down the highway most of the time your off boost. Yes keep a clean filter on it but ive done all mine and everyone i know did theirs and never any issues. In fact we saw longer life spans on our compressors
The older style ones took it directly from the intake manifold which introduces turbocharger oil blow by into the air compressor head. The new style ones do not however, they take it from directly after the engine air filter. I was going to say something to the effect of what you had said, the air compressor does not required pre-pressurized air.
Detroit had such a problem with the ceramic rollers failing they had a service bulletin for transit engines with service part numbers to use steel rollers. I prefer to use those on truck and marine engines when going into them even though they didn't have as big a problem as the transit engines. As far as the air compressor, the particular Bendix compressor that appears to be does not require boosted intake air. The reason for boosted air to the air compressor was not because it's cleaner, but because the in theory when the compressor is unloaded the air pressure from the intake will help keep the rings sealed and the compressor won't pass as much oil as one naturally aspirated. Many OEM instillations used silicone hose for the compressor intakes as well, not my first choice but it's not "wrong" either. I agree that the gas engine valve cover breather shoved in the intake hose isn't the right way to do a compressor filter tho!
@@MrTheHillfolk That was probably quite a sight! That was one of those looks great on paper designs. But overall, the 60's are great engines and what engine hasn't had at least some growing pains.
@@speedandmarine9066 Yea man stuff happens. It was depressing seeing the 2 stroke line condensed to 1 single line though. If I like the 60 series, a lot. It is simple, has decent power,and the cost isn't too bad. Good all around workhorse.
Design choice for the Detroit 60 series for wear resistance. People think that the ceramic is not as hard as the cam lobe, on the contrary, the ceramic rollers they made for these rocker arms are far harder than the steel. Hence why this one cracked and broke. I've heard of people dropping these rocker arms on the ground and the ceramic shattering from the impact.
I believe who ever did the overhead messed up. Probably set one too tight, piston hit the valve and shattered the roller. The ceramic is softer than steel obviously. I would check for engine over speed codes as well just in case.
ThinAir Diesel I was at the factory in 99 for training. During the tour we saw they popped a ceramic roller in a 60 and they were picking the pieces out with a grease covered stick. The 2 stroke production would end a few months later, glad I got to see a little bit of history.
They say at overhaul for replacing the balancer in manual 😀. Did you see any rust in that hole we have also had these valves bind in the head so much so that when you hit it with a hammer it sounded like it was part of the head real sharp Ting. Did you see any tap marks on the Piston?
Brian I would like to get you to look at my 359 with a bigcam 3 I live in tn I don't know much about these but I'd like you to straighten it out for me
Had a detroit 60 series do the same thing on all intake rockers replaced all intake rockers and reran the rack. Runs good. Do know what's causing the issue but I've seen a few
Same here. Happened on #2 fuel injector follower. It’s a material failure, Detroit came to our shop because it’s happened so much across the country. Moral of the story is, drivers love Detroit’s for fuel mileage, mechanics hate them, and this mechanic is one of them. Worthless boat anchors in my opinion.
@@Seveneleven44 TOTAL BS Bro. You can get a two year old to work on a series 60. If you're speaking about a DD13,15 or 16 then that's different. ANY preemission engine if properly maintained is NOT a boat anchor. You sound like a simp for that statement kid.
What you're trying to say re the previous rebuild is that it absolutely REEKS of AMATUERISM. Umm re the bent valve, that begs the question how? It is unlikely the piston hit the valve and smashed off the rocker. How can it? - short of a foreign object. Maybe it ate a fitting or a compressor vane or a bolt/nut etc. I reason what may have happened during dodgy brothers rebuild is the cam was put in the head and they tightened the rockershaft without consideration of the position the pistons were in, ie the motor wasn't timed. They realised what was happening but not before they cracked an arm which went unnoticed and it developed into this - just an idea.
Just did an in frame on a DDEC VI series 60 and we fired it up and road tested, one of the reman injectors failed along with the follower cap in the fuel cam follower. Fucking Detroit’s are garbage. Cry all you want about fuel mileage, there’s a reason they are significantly cheaper to rebuild than Cummins and CAT. Boat anchors. Just like the “hallowed” Mack e9 V8’s. Never understood the admiration, they’re junk in my opinion.

Ceramic rollers are actually harder than steel just more britel they don't take shock loading at all
The rollers are ceramic not steel?

Ceramic has low lubrication requirements and can carry a heck of a load , just don’t shock it or else blammo
Trying to establish CAN network between Woodward Easygen 3500XT and DDEC 4. Please help

The ceramic is way more harder than steel, thus verry brittle.

What do you think, they set the valve lash too tight when they ran the rack?
Thanks for share you expertise
i myself have seen a few of those rollers break mostly on the injectors bent valve been a reman head id be looking for warranty

S475 or S480 borg warner turbo?
S475
11.1 & 12.7 were great motors, the 14.0 i've had a few ptoblems
14l is a great engine the egr and Vgt are the only emission components on it, it's so simple
Ddec was better than ddec5

Squarehead for you...
DDEC IV I thought was a wastegated Engine. Didn't see a wastegate on the turbo?
I have a DDEC IV non-wastegated in my glider
Depends on thr build..all my Detroit's had or got gateless. Turbos
@@Stephen-carr ddec iv has wastegate but can be changed
They all come with waste gate u can change the turbo
DDEC 5 used a vgt turbo, no waste gate on any of the automotive engines, I don't know about marine or industrial
maybe bad valve adjustmenr
dampner is filled with oil not jell
They definitely aren't filled with oil.
