flan,
lol, ouch. Sucks for them. Good find.
Hamilton has been working to refine / streamline the kit to make it more affordable in terms of the component cost. Still going to be labor intensive for the install though. It can be done without lifting the cab, but lifting the cab is by far the preferred method. Especially considering there’s a potential for complications like stuck cam bearings.
Ditto
Although they didn’t rectify the source of the “tick”, it’s a good thing they did the cam and lifter swap on this engine. The cam lobe with partial wear contact at the peak of the ramp, as well as the lifter above it, were destined for premature failure. That level of partial wear on the lobe is indicative of a lifter / roller assembly that was not running parallel to the cam. Would be caused by either a poorly machined roller axle bore in the lifter body, and / or a roller that was not uniform in its bore. Either one (or both) would create a scenario where all of the force applied between the roller lifter and cam contact patch was being applied to one side of the roller rather than across the whole width.
I had not heard about that refinement, where did you hear about that? I’d be curious to see what it takes to make something like that more affordable. I did see wagler will be releasing their own solid tappet kit in the coming months.
For anyone who didn’t have time to watch the whole thing they diagnosed the truck, felt very strongly through diagnosis the noise was valve train, disassembled the truck found evidence to support their diagnosis, put it back together to have it start making the noise again…
If the Hamilton kit was on sale for 95% off, then maybe I could halfway afford to pay the labor to have it installed.
Its communist California, so like EVERYTHING in communist California, its way more than anywhere else... and not as good. Pay more, get less..... the democrat way.
I figured as much. Although I was born there and spent my toddler years there, I have had absolutely no desire to step foot in that state due to my personal “convictions”. Same reason I never stop when passing through Illinois. I refuse to spend my money in commie states. Minnesota same. Too bad, beautiful scenery, but I don’t travel where my constitutional rights are not respected. I still see the need in the cam/lifter change due to the metal and wear they found. Those flagged lifters are asking for trouble.
Even with the cheapest labor in the country, it’s still a minimum eight thousand dollar job if you have a shop do it.
do you know if Hamilton is working on a kit for the 2025+ trucks? i see Wagler has a flat tappet conversion kit out/coming out soon, but I wonder if they will have a kit for the 2025+ trucks as well. i think Manton is making some of the components for the Wagler kit.
I do not know if any of them are working on a 2025+ kit. However, I would assume that this would be the case given that the valvetrain remains largely unchanged and they’re in the business of selling parts. They’ll need to keep up to be competitive.
Hamilton and DNR Customs are working on a kit for the 2025+ trucks. It will be mor expensive due to the new rocker arms.
Anytime you see restrictions on parts, it’s usually either due to low production volume or a re-design due to flawed parts.
Expect around roughly 30 hours of labor with all the little odd and ends like, fluids, gaskets, etc..etc.. The cab has to be lifted or engine pulled for this job to be done....both of my trucks, the rear main seal always had to be replaced due to leaks...go figure...And depending how many miles are on your truck..some things should be replaced as preventative maintenance while you're in there..best time to do it...I always updated the valve springs and bridges and got rid of that plastic heater hose nipple...and its the best time for a coolant bypass...ALL of that stuff adds up in the end.
