New Toyota Tundra’s Recalled for Spun Crank Bearing

[Renze]

It’s really pretty sad what happened to Mack.

You mean their E7 replaced with Volvo engines ?
Renault owned them before Volvo bought Renault Vehicules Industrieles.. If you rip the Renault badge off a valve cover, theres Volvo written underneath.

Most brands of trucks were bought out and consolidated here, in the 60s. Britain had lots, and now their ERF and Foden are rebadged Daf, all under Paccar. Germany had several dozen of brands, now only two..

I forgot to include the reply from the service manager.
He told me around 85,xxx miles was when those trucks began to leak oil.
I might have to swallow my pride and buy a different brand next time.

Don't matter what you buy. They're ALL junk now. So just keep getting what you like and roll the dice, LOL

Planetary end reduction is standard here on anything above 11.5 ton or 25.350 pounds.
All above mentioned construction trucks in Europe have planetary reduction, and 13 or 14 ton axles even though 19 ton is legally permitted on tandems.

And 110k is 50 ton, is that tandem or triple ? Because AFAIK Freightliner uses Sisu planetary axles if any

Rigid Axles - Sisuaxles - Professionals in axles

Available in single – tandem – tridem combination. Single or dual tyre mounting. Deeper ratios and higher weight ratings for slow moving applications.

Here in Europe, single order heavy duty oul field trucks are the domain of Titan which uses Mercedes components

In the old days there was Berliet, later taken over by Renault which is now Volvo. With a Clark box and Cunmins VT1810 V12 it was the worlds biggest truck in 1957. Neither of them still builds trucks this big.

The Stars have Axle Tech, which used to be Rockwell. Axle Tech and Sisu are the only two that can be ordered in Canada as far as I'm aware.

Daf nowadays uses Meritor. Their own 13 tonne planetary axle was introduced in the early 80s, and was dominant in the then evolving tractorpulling scene in Holland. Rolls Royce Griffon in front and 30.5R32 tires on the back (the big Tundras werent around untill the mid 80s, let alone the Michelin 1050s) and they held.

6 or 7 years ago i saw a Scania 164 V8 puller truck, estimated 2500hp, with a Daf 13 ton axle. Thats blasphemy to Scania enthusiasts, but hey, they needed a cheap axle that kept together

Off course the market has moved away from planetary reduction: when i was a kid, they even put them on garbage trucks to save the clutch at this start/stop work (yup, no Allison) so they arent as commonly available as they used to. Nowadays garbage trucks have an AMT with low 1st gear, and the fuel penalty of a planetary axle is avoided.
Off course modern truck engines have max torque between 1000 and 1600rpm, while 40 years ago the turbo would barely spool up under 1600rpm. That has decreased the need for ultra low gear reductions too. Plus, a crawl gear in the main gearbox costs less fuel than a planetary reduction..

Planetary reductions nowadays are found on construction vehicles and heavy haulage above 80 ton, in Europe.

Oh, a good story from my old neighbour who drove a garbage truck: the pencil pushers at the officr thought they could move a 25 ton garbage truck with a 7 liter engine if it had an Allison, it would cost the same as an 11 liter with an AMT.
Drivers hated it, because when they had the PTO engaged the truck would auto idle at 1200rpm. And at 1200rpm the Allison would not have enough output torque to climb a kerbstone ! So they often had to disengage PTO to be able to manually throttle over a kerbstone or one of the many speed bumps in small inner city streets.
Next to that, blending in after the on-ramp driving back to headquarter, you required a death wish. The highway crossing the city is elevated so that the small roads can pass underneath it every 500 meter or so. But if they had to climb onto highway level from a standstill with 25 ton and 270hp they could just hit 35mph at the end of the blend-in lane, do they could either emergency brake and wait till rush hour was over, or steer into the lane hoping that other traffic would move over.

Not sure, but i think those Titan oilfield trucks use Kessler axles. Kessler is big in AT crane axles, among others, Liebherr uses them.

They dont make on-highway axles: you just cant build mass produced, cheap to the cent but still reliable, within the same corporate culture as bespoke, heavy duty, using extra steel in the limited production numbers is cheaper than engineering weight savings to the gramme, heavy duty limited production axles.

Thats why i think sooner or later a small scale specialty builder will jump in and build these severe duty trucks instead of Western Star, which is held back too much by the corporate structure and mass production mindset that the FL mothership has...


For the same reason, Agco quit Terra Gator just after modernising their entire product line up. Then Ploeger/Oxbo hired the former Terra Gator product manager/sales chief and started building slurry trikes: As a builder of harvest machines, with a peak during summer to get products moved to the fields in autumn, the peak of slurry machines in winter to move them in the field in spring, fit their production scheme voids like a glove. As well as the production numbers that come with specialty machines fit Oxbo/Ploeger much better than Agco.

I didn’t know Cummins owned Meritor.

I have a Meritor 16K front axle and a Meritor 30K rear axle with driver controlled locking differential in my IH-7500.
My transfer case is also a Meritor MTC 4210.
And of course the Allison RDS 3000 5 speed with PTO provision.

Really, that’s sad but true.
I cannot believe how unreliable and complicated things have gotten. Even now, they still have trouble with reliability and high operating costs.

Whatever the future brings: more decades of diesels, or natural gas or hydrogen combustion, fuel cell or battery electric: The trucks of the future will need to be powered either way.

The safest bet Cummins could make for the next century, is bet on the entire power system between gas pedal and wheel. Whatever it is going to look like in the future.

The Tundra's are still having engine problems. This one didn't even get 2k miles on it and needs an engine.

So, I Just Bought a 2025 Toyota Tundra TRD PRO Hybrid, Headed Out to Maryland, Made it 400 Miles and the Engine Locked Up With Only 1,528 On My Truck

Hopefully the new fuel agnostic B 6.7 Cummins will be a winner which I believe it will be since they build/built great 5.9's and 6.7's not to mention the larger engines.

Cummins 6.7-liter gas engine part of new fuel agnostic strategy

Makes me think of the Ford world series tractor engines, build the diesel first, test the daylights out of it, and then make a head for the gas or propane version.

If it can live a long life as a diesel with the increased compression required, for gas use reliability- the engine is already overbuilt.
