Liquidator pistons

[certifiable]

I have been off site for awhile but I got the word this spring that there are guys that want std Liquidator pistons.
I talked with Wiseco about the pistons and also the WRIST PIN BEARING since I do not have enough bearings left for another run. I asked Wiseco if they had any 19 mm bearings and told me they did. I wanted to make sure that there was a match, so I sent a sample down to see if it would match up and they spent a few weeks looking for the correct size, last stop being Japan. no go....none available.
As I see it now, that give us two options. One is that you guys will have to talk it up as to who might have any of the JD bearings left. I can get the pistons made......each person has to find bearings. Option two, as presented to me by the Wiseco rep, is that we go with 18 mm pins. Wiseco has an 18 mm bearing that has the proper length and outside diameter dimensions....but an 18 mm inside diameter. Those are the two options.
I can get the run split into two parts......19 mm (you find the bearing) and 18 mm with Wiseco bearings. (Everything else about the piston will be as before).
Ok...you guys talk it up and decide what you want. I would like a committment either way so that each guy gets what he wants and nobody gets disappointed or mad. It will take about a month after everyone makes their decisions.
I think you can leave messages here.....correct me if i'm wrong....or my email address is houge@mnstate.edu and hard line phone is 218-861-6175....cell is 701-261-8214.
thanks,

Larry, as long as they will work on the original Dator rods it doesn't make any difference to me what pin is used, as I won't be able to find any OEM bearings anyway..

But that being said I will need one piston of my order to be with a 19mm pin to match the new Wiseco piston from the other run I've managed to misplace.. The rest of my order can be 18mm pins & bearings..

By the way welcome back on, & thanks for doing this again..

Thanks Larry

Agree with Kenny... As long as they fit the Dator standard rods it makes no difference with me. I believe the outside bearing was 23mm but not 100% sure ..... Also if not to late can you add another 5 sets on to that last number i gave you.

Thanks again

Hello there .I will take mine w the 18mm setup,As long as everthing works with the dator rods .Thanks We sure do appreciate what you are doing.Brock

I have to ask the obvious question here, but if you have these made with 18mm wrist pin bores, then are these basically a 340/S piston? They are both 340cc's and use the same rings. I don't have a Dator piston to compare to a 340/s piston against that's why I'm curious. Sorry if this muddies the water. Just seeking clarification.

Interesting point Troy.

Troy & Todd, I believe that the Dator has the pin location lower on the piston & I think the piston is taller all together on the Dator also, I will ck one each of my pistons this weekend to make sure..

I swear that T-roy never sleeps!! Always thinking!!!!!!!

As Kenny said, the L piston crown is higher and piston is longer than the S piston. I did not have the right stuff to gauge the rod width and do not have an L crank here to check if there is a difference.
good question.

Hey Larry, thanks for doing this!!

Thanks for clearing this up. I have always wondered what the difference was between Dator and S pistons.

well i dont really see any need for me to order 19mm pistons if there are no bearings available for them . i am assuming i can purchase the bearings with the pistons and pins , as things go i could see the 18mm bearings be discontinued or dry up in time and be no longer available too ,at that point the 18mm pistons would be paper weights because there would always be the chance of finding used or nos 19mm ...well a chance !! wade

What???????????????????

[lwb140]

well maybe i wasnt clear i guess , since i dont have any nos 19mm wrist pin bearings laying around . i may as well order pistons that i can get new bearings for . i think its important to order the 18mm bearings for the pistons while they are available especially if they arent used in something pretty common and mainstream . my consern would be that if i purchased pistons to use an 18mm wrist pin and the bearing to make them work on the dator rod became unavailable then those pistons would be ash trays . i wouldnt feel confortable buying pistons that use 18mm wrist pins and not buying the bearing at the same time . in other situations ive seen people try to save money by not buying the required parts to complete a project up front while its available ,then when the parts ,[in this case 18mm wrist pin bearings ]become unobtainium than they are screwed
does anyone know what the 18mm pin bearin fits ?if its something that is still in production it may very well not be an issue ,if those bearings are something that is old stock that supply will run out on that may be a different situation am i crazy ?

so are the 18mm bearings out of something as common as a 350 chevy or as obscure as a 54 studebaker ,are the bearings in deep supply or will they fly off the shelves as jdsledheads order them and the last one of us to order are without , just my thought and conserns ,im sure you guys have this figured out an under control

thanks again guys for taking on this project for us wade

I was confused too.....Larry said that Wiseco has the 18mm bearings, so they're available. Your point is what if they become unavailable later - which is a valid concern, so everyone that needs the bearings should get them with the pistons.

A friend of mine had a 2004 Parts Unlimited catalog at a show over the weekend - I was bummed over all the stuff they used to have available but no longer.
