Machinests measure clearance off the installing pistons, this is a royal F%#ck up, totaly amazing people can do work like this, the engine tech had to grab the wrong pistons. You can win in a court of law (small claims) and never get paid, be prepared to trash talk the business. Let's hope they step up.

 

True. Wouldn't think that the piston would have much to do with oil pressure tho. Pressure points from my understanding are the pinion bushing, rockers, and push rods everything else is "splash" fed so to speak. But I could be wrong. Still in quote stage with mechanic. There master mechanic has been doing the work and he has had to be away from the shop the last few days. Will talk to him on this when he gets back. Not as much conserned with pressure now from reading other threads but if he suggests the rebuild or replacement is more of the question. I believe the ss pumps provide more flow of oil to bottom end at idle.

 

In my opinion you should never hook a pressure gauge to a Harley. Most people don't understand the difference between shell bearings and rollers. Your car needs lots of pressure, your Harley doesn't. If the oil light goes out at idle you have enough pressure for a Harley. Having enough oil round the bearing will make it last a very long time. Having more than you need won't extend the life of the bearing as evidenced by the thousands of Harley motors that go for ever on the stock pump.

You can fit what you like but some of the after market gear out there uses paranoia as a marketing tool. Its only the lifters that really need pressure on a Harley.

 

Spanners,
You mean two .020" pistons don't make it .040"??? LOL!!!!!

lol, you would have thought so eh?

 

Thanks spanners they verdict is still out at this point. Was just a thought I had and the other mechanic suggested it while it was this far apart and the pump being a 93 it might be beneficial to do it now. He said it was about 4 hours labor to remove and install a pump plus whatever damage it might cause if it goes out. I have no way of telling how many miles it has on it or even if it came on the bike. With old builders record so far it could be junk. New place said about 150 to rebuild pump. About 350 for new. Just don't want to tear this all down next year cause of a pump. Guess now I am asking you new or rebuild.

 

the shop that did this will not end up fixing the second issue - that being the pistons were causing a real hardship for the engines roller bearings, the engines 45 degree angle and the way harley motors are designed, that sort of chuckling in the cylinder has already dented both cylinder bores, and put strain on the lower units roller bearings -- a couple of 100 miles after they fix whats up with it now it will probly fall apart -- SORRY to be the bearer of thas sort of bad news --- johnjzjz

 

I really don't think so....roller bearings don't die from being shaken about...if they did then my Ironhead would never have survived...it ran for moths with no oil pressure until I installed a new pressure light and found the cam bush was rooted.

Don't make pronouncements like "it will fall apart in 100 miles" when you have no facts to back you up.

 

As I said to HarDlife.....its your dollar...those pumps can eat gravel and still work, I have seen some awfully scored pumps delivering great oil flow.

If ya got the dollars they will buy you peace of mind...I don't need peace of mind, I fix my own bikes

 

I have owned a bike shop since 1965 and still operate it today, its nice to hear you once owned an iron head and from that experence know what happens inside one, the Pronouncement was from experence not owner ship

Prehaps you could enlighten me, my shop used a metal dumpster in the past, from the offerings to the God of speed - you probly would not believe what i have seen roller bearings do and from what -- johnjzjz
