It would cost too much for them to actually do R&D some times. Ya sure they fit, "lets order them from a company out of the country and sell them as being a fitting part because we have done testing of our own and they work"
Obviously not, if I yanked mine back of after 2200 miles of use and had rubbing, and their solution to this "new found common problem" is to run two front $6.00 gaskets since it seems only a few people are having these problems, that just shows me that they did no testing other than slapping a set on a motor and said "yup, these fit, lets sell em, cause people will buy them if they know they will work cause they trust us".
Just burns my butt when people we should trust to do the research of the products they sell, fail us like this, and get busted on it, and their solution is a double front gasket. I just have to LOL at these people.
You know who I really feel sorry for...is the poor guy on "the other forum" who had his snag on his oil pump cover and his chain break sending valves into pistons and pretty much trashing his motor. Some said it was an install error...I beg to differ after seeing everyone else's rubbing issues.
I thought machining the oil pump cover down some would be a fix, compared to running two front gaskets and mis aligning things on the front of the motor, but Reptile did both, and still had a failure. Lucky it wasn't an engine failure all together. What the one guy who discovered the "missing chamfer" found, and what Reptile experienced is more than enough proof for me to yank mine and have the inside of the back side of the crank gear machined on a lathe here locally.
It was no time at all to do this work here once we figured out what angle to machine it at. It took him about 5 minutes to load it into the scroll chuck, center it with a dial indicator and set up the rest of the lathe, and then about 5 minutes to machine it. Nothing to it. Ran me $10.00 whoopie doo. Cheaper than costing me a motor thats for damn sure.
Sorry for the vent, just still pissed that company's pull this stuff on their customers. It it were me, and my company...this would of never happened in the first place. But personally if I were them now, I would be buying a whole bunch of crank gears from the company's who make the double rollers they are selling, and have them all machined ahead of time, and send them out to EVERY customer who can verify they purchased a timing set from them, and send them out a FREE machined crank gear, AND a new front timing cover gasket as a way of saying "sorry, we lied about our R&D, and these working just fine." But thats just me...and how I would run my business so I could sleep at night. But I guess everyone has different morals.
