    Confused Taylor soft serve

    Hi I am working on a 30 year old two head machine this unit should be in the graveyard. It has 409A in hopper compressor, 408A on one side and 134A on the other side. The complaint was ice cream not coming out fast enough and product spoiling in hopper. I think the ice cream problem can be solved my using metal scrapers instead of plastic and correct me if I am wrong. The ice cream temp is 19 degress. The hopper refrigerator is working good but I do get temp difference from the front to back 37 degrees in front and over 50 in back can this be a bearing problem on the auger? Next question is can this problem be solved? Thanks Paul

    I just fix one last week.
    Problem is the gear box worned -out.
    And I have to replace the bearing kit and lubrication.
    Have you replace the bearing kit every half year?

    Let me guess, the hopper used to be R-12, and is a cap tube system. If my guess is right, try recovering the R-409 and replacing the cap tube and filter. When R-409 was first introduced, it was advertised as a drop in replacement for R-12, later they found that the cap tube wouldn't work, and recommended it be replaced with a longer one. Take the compressor hp and cross reference it on a Supco cap tube chart, as the factory isn't going to have any recommendations.

    Yes the hopper used to be r-12 but it has a new compressor with 409A in it, I am not sure if the tech that replaced this compressor changed the cap tube or not I will take your advice and check this out. Thanks Paul

    recover the ref in the hopper system and replace the cap tube you'll have to contact your local distributer to get the part because taylor wont deal with you direct and as far as it not coming out fast enough has nothing to do with scraper blades (plastic is better) when the product came out what was the temp and also when you replace the cap tube and recharge it put new mix in it and wait about 2-3 hours before you check your hopper temp due to with out an agitator the temp will vary but not that much

    and also did your pressures seem wierd on the hopper system

    Okay good advice it is my understanding that the metal blades will last longer as well as scrape the ice cream off the tube better and help with temp. The ice cream temp is 19 degrees, I am guessing that the plastic blades aren't scraping enough off cylinder wall and it is building up. Correct me if I am wrong. I am not sure what the pressure should be on 409A I dont have much expierance with it but when I checked the chart I am going on memory here it has been a while I think the temp was -15 according to pressure. I would like to investigate a different refrigerant for this compressor I will have to look it up. Do you think bearings have anything to do with this I am not sure as both sides are doing the same thing. Thanks Paul

    We have used R 414 in hopper with success. We also recommend tune up kits, which include blades, every six months or so. I don't think bearings are the problem, some Taylor machines require a special alignment tool(Wendy's frosty machines) and bearings are a real pain to change. Your product temp seems ok(18-20). I'd check what overrun they have the machine set for and also check the density setting potentiometer.

    Hi Thanks for the reply! I am still green when it comes to taylor machines I did tell my customer that I knew nothing about this machine but that I would take on the challenge if he would be willing to be patient, he agreed and he has been very patient I did find out from an employee of his that he has had four other guys out to fix this machine and I am the only one that could get it to make ice cream. My question to your reply is did you have to change cap tube when you used 414 in hopper compressor? How do you check overun? And what is a Potentiometer and how do you check and adjust this? Thanks again paul
