D10T - 777F - D8T Cam failures

[Gavin84w]

Just had 5th Cam failure in 7000hrs on our D10T. Hope these updated cams and higher oil pressure works. Can't afford anymore.

Something radically wrong there, i have customers with 12000hr D10T,s and everything is original, we adjust valves as per OEM and change oil 250hrs.

If the machine has Productlink and you are hooked in to visionlink you can look up the flashfiles from sitting at your desk.

We have access to Vision Link, but what is the product link?

We're overhauling a D10T right at this very moment and the engine had 17,000 hours on it (for reasons I don't want to go into here) when it was removed - not a single cam failure.

Product link is the hardware on the machine, vision link is the software on your computer.

Late Breaking News ...............!!!

We have 2 x D10T (one new last December & one recently overhauled with a Reman engine in it) that are producing soot at double the values of what we've been used to seeing before. We see around 35-40% soot @ 250 hours on oil compared to around half that for our older tractors where engines have not been replaced yet. Only difference I can see is that the newer engines are using a software about 3-5 generations newer than what's in the older tractors.

Key will be the D10T we got back last Friday from overhaul with a Reman engine (and of course latest available software) in it. You can bet we'll be watching the SOS on that one really closely.

I have officially run the flag up the pole with Cat on this one. Watch this space ............

Currently running several of the updated Cams in D10T and 777F. Also the updated oil pump spring is completed when the cam and rockers are updated. Hope this is the fix, we are currently doing 3-4 cams a month right now. Almost every time we open one up to do the recommended valve set we find a shot roller and spalled cam!! Costing us big bucks.

I am told Cat has released another letter on Camshafts, Rockers and Rollers. Has anyone seen it yet?

Specifically what machine model and S/N prefix are we talking about..?

I found this today after doing a set of injectors on an RJG prefix machine.

That's a Service Magazine. What post #47 was enquiring about was a factory Support Program. For RJG-prefix D10T there were 2 programs published on 5/5/14 titled "replacing the upper valve train mechanism on certain D10T tractors". I have no info other than that.

Just had to replace a cam in a dump truck with a C15. Never had an issue in any truck prior.

Yeah, found they finally published a new service letter for it. PS52662, After failure only.

That letter doesn't come up for me, must be dealer access?

It won't come up on Customer SIS-web. However you can use it to browbeat your dealer if you have a cam or follower failure.
