Unfortunately, it was a poor experience with order 250491. It covered 30 items, 59 articles at a cost of $696.39. First Crowlwey told me that are waitng for ten articles to complete the order and then ship in one package. I received a unexpected box with 3 gaskets that DIDN'T BELONG TO THE ORDER. After claims were found and shipped the 10 articles that were waiting for. Crowley maitained the the point that the 3 gaskets were the 20 articles missing, but never explained why shipped splitted in two shippins when the agreement was one and where are my 20 lost articles and my money. IT WAS GREAT DISORDER AND A REAL DISASTER

Still waiting on one part that when I ordered was told it was in stock. Also, $8 for an O ring. Sure, I get it, nothing is free but I would rather see a realistic price and be told there's a minimum charge for any order. Also, there may be value in grouping items into repair kits. I ordered water intake screens and had to order individual screens, screws and nuts. Logically, that should be a kit.

Their parts breakdowns are very good, but in my particular application, they were not all the correct part #s. Their pricing is very reasonable. Trying to get a real parts person to help you on the phone with the right part selections can take a while. All in all, I would definitely order from them again.
