Gaterman GP-1023 Lifters Long Term Wear

[rbabos]

Bearing Skate from SYN Oils 

Excuse my ignorance but if there is enough friction to wear from "skating" would there not be enough friction to roll the bearing?

Skate can occur for other reasons too. In a case of a lifter it could be not maintaining full contact on the cam at all times. No oil will save this slip chatter effect.

I think it was skating because the roller bearing was going out.  Like I said earlier, you can really feel it (the notchiness) in the bearing.

What do you guys think the spring pressure should be at installed height with a cam like that CR575?

I've got one Gaterman (front exhaust) that bleeds down overnight=cold rattle for 30 seconds. Just came in from re-adjusting, no difference. The SE pushrods have about 78,000 miles on them, so maybe an end on that one has a wear pattern unlike the others and is the culprit.  Do any of you replace the pushrods after a certain amount of miles?

I have a similar situation, front exhaust a bit noisy when cold. When the motors warm its better, but always a slight tick. I readjusted them last year, and again last weekend. Still there. The noise doesn't bother me so much as, it wasn't there in the beginning. These have around 7,600 miles on them.

Could also be the chicken or egg conditon. Which caused what first?
Can't help on the springs.

My front exhaust knocks terribly on cold start, takes about 15 seconds to quiet down, then very quiet. Have about 10K on the lifters.

Guess my reply didn't take;
Anyway my front exhaust knocks terribly on start up (cold) gets quiet after about 15-20 seconds, then is very quiet until it sit's overnight again.

Brian...I thought you was going to give the S&S premium lifters a try?
I was going to ask you the other day if you did...and how you liked them.
Hold out a little...I think there is going to be a new lifter come out real soon...I can't say no more than that  [attach=0]

Here are some 99c lifters with 3k miles on them I took out today, bone stock bike syn3.

[No Cents]

damn Joe...are those pit marks on two of them...can you feel that with your finger?
It looks like you could.

Did you happen to check the clearances of the lifters to the alignment pins?

I was, but that was when building the 124, before the 107 went sour. I wasn't planning to replace these just to replace them. But late in the year the front exhaust started talking a little. Did I ever mention I'm hard on things?

Will most likely buy a set of the S&S premium lifters this Spring and try them out.

[jrgreene1968]

I hate reading this thread..ive got a new set of the gatermans I was gonna install along with a 98" etc..but now im wandering if maybe I should try a different brand. Im running woods now..actually not impressed with the woods..got 1 that bleeds down from time to time. Are the s&s premiums better?

[Deye76]

Since the "B" lifters are no more it's probably a crap shoot. Can't believe how many times in the last 40 years, that the next new lifter coming out will be  "it".

Don't let a thread like this put you off, install those Gatermans.

I took a set of Gaterman out last week on my 120 with 25K miles,  put in a set of S&S premiums w/ limiters,  I set these one turn back,  the Gaterman were set at 3.5 turns with S.E. Taper rods.   Got 500 miles on the S&S already and like them, nice and quiet on cold starts and hot.   definitely quieter than the Gatermans.

Got a 13 in today with stock lifters with one that takes a few seconds to pump up on each start, will be interesting to see if they look like yours.

I'm definitely not saying they're bad lifters.

As I believe given enough time, heavy springs, high lift cams, I can tear any brand up...   

[JohnCA58]

I agree with you.  Gatermans that came out look good.   Just going to play it safe and change out at 25K mile.   Called PM service

Heck!  25K on lifters and your not happy with that?  I do 15K between changes and happy with that!   I have run 662-2's and 640's and have never had a quieter or better performing lifter.  2 sets into it and they came out looking like the day they went in.  No complaints here.  Personally I would not push a twin cam lifter in a performance cam profile past 15K.  Too many factors involved and a lot of pressures on those lifters.
Very cheap and easy item to replace so I personally see no need to push the threshold.

I could feel it with the end of my pocket screwdriver.

I'll snap some pics tomorow but the cams are not as bad as the lifters.

I did and they were both .008 with the 99c and .006 with the 850-1 lifters.  Gotta start getting some oversized pins in stock.

[N-gin]

Curious if anyone measured the radial play on the axle?

So the lifter rollers are frosted and the cam looks good?

You have never installed a new set and had one or two , that wouldn't stay pumped up ?
It blows my mind that you can install something that is brand new and it isn't as good as what you took out .
It used to be so easy . Now it takes a prayer meeting every time you install half these B knock off's

[TweekmyTwin]

Seems the last two set I installed ( Gaterman's ) had one lifter never pump up on each motor. My luck with them has been bad so back to Fueling or S & S. Just my experience but most of you guys are having great luck.. I could use some...

Shaking a dead chicken helps..

Chicken or No Chicken , I went back in and Loosened my lifters to re set them...

EVERY Time  a thread like this I THINK I can hear noise.
Never,,, "Did" that sewing machine sound change BUT I "did" the re-set of the gatermans to 3T+3 to 4 flats from 3T of original setting... (21/22 flats on SE slender's at 24thrds per inch).

I Thought I could hear More noise on a 3 day run here in Az. Now, I really hear no difference than the Original sewing machine noise that was there before the added adjustment. (Never checked further to check pin play or looks of the lifter..... felt no need there)

When I first set them they sounded like they do now and Only IMAGINATION and Muffled ears make a Sound change here.

Have you ever notice; when your ears have Not Popped you can hear every noise in the motor... Better than a stethoscope...

If I would only quit reading about the problems and wait until I have or Hear them OR like many do AND I Will : change out at 25,000 miles........ 11 thous to go.....
