Roller lifter pushrod seat

Post  68galaxie on October 14th 2014, 9:33 pm

Has anyone seen this before?


Crower severe duty Hippo lifter. All other lifters look great. Time on lifter 20 minutes maybe, mostly idling and a couple of second gear blasts down the road.

Looks like machining chatter. This lifter is the one where I had experienced valve tip wear. Engine builder thought lack of oil or soft valve tip.
Looks like one would not get much oil up the push rod on this one?

?

it could have had a machining flaw and made the marks in the beginning of start up and then smoothed its self out, thats why you got the lifter tick??? (its a thought) confused

Crower should replace the lifter i.m.o.

could it possibly be valve float?

You can see that the seat area has what looks like chatter marks - not a smooth machined surface (like the rest of the lifter push rod seats)
I am not sure valve float would cause the poorly machined surface?

I sent the picture to Crower - haven't heard a whisper yet. I don't actually expect any response. I am not a big purchaser of Crower parts - just a
floor sweeper.

That looks like chatter from breakage or dull tooling.

Have you talked with any one? I'm pretty sure they would be willing to take care of it. I can contact Dan if you'd like.

I agree...it looks like a QC issue from tool chatter.

I did not look closely enough at the push rod seats in the new lifters. Actually when the lifers are new and no wear ring visible it is difficult to see.
I had no idea I needed to inspect the lifter push rod seats - I guess I have learned a lesson - trust no one!!

The only contact at Crower I have is their email tech line. I have no idea who I would talk to.
Do you have an email addy for Dan?

I think its more a matter of-despite the best efforts of quality safeguards in place, honest mistakes happen. The human element pretty much leaves it on our shoulders to inspect and approve what we put in our engines. These companies have the best intentions to put out quality products but sometimes one will slip through the cracks.

Need to call them on The phone and talk with somebody. Emails generally don't get someone's attention., especially sending Something to a general account.

IF its a QC issue,i agree it is good too look things over before installing.BUT,a high end manufacturer like Crower,a guy shouldn't have too worry if its QC is up to snuff before you install it. I'm sure though that Crower will take care of it if its a QC issue.

Update

Post  68galaxie on January 23rd 2015, 10:42 am

Well I have been waiting a long time to get a response from Crower.
I called on the telephone and chatter with Jerry. He said to send him pictures of the lifter seat. I did. December 4, 2014.
I waited a week and sent him another email asking if he received the pictures I sent (as I had not had any response). His reply in capital letters: YES I SENT IT TO THE MACHINE SHOP

I guess its Crower's way of saying PFO?
I have now waited another 6 weeks no response. I just sent off another email to Jerry.
A very polite one as I do not want to piss him off again.

I know Crower components are usually well made, but when you do have a problem who do you call or what do you do? get lawyers involved over a $100.00 pair of lifters?

WTF? Really, that is the product support one gets from Crower? I feel like throwing the other 7 pairs of lifters in the garbage and purchasing something else.
