Expert Answers about Performance Tool

  • Is a Solar Powered Battery Charger Good for Charging a Trailer Battery that Powers a Winch
  • A solar powered charger such as # PTW2997 is a great option but can take a long time to charge a battery; especially a battery large enough to power a winch. If you go solar make sure that the battery is fully charged before winching so that the charge (hopefully) lasts the whole time you need the winch. That way you aren't relying on a charger to charge up the battery since it will take a while. Another option is a DC to DC charger that you can keep mounted on the trailer and attach...

  • How Many Watts Does 12 Volt Heater PTW5009 Draw and is it Ceramic
  • Heater # PTW5009 draws 13 amps at 12 volts which equals out to about 156 watts. I did a little research and from what I could find it is not ceramic.

  • Do Mobile Home Axles Have Weight Capacity Rating
  • Mobile home axles are designed for a one time use and do not have a load rating. You may be able to find hubs and drums and other hub components for the specific spindles you have on the axles but that can be very difficult as mobile home axles typically have non-standard sizes. I have attached a drawing that shows where you would need to measure on your spindle for the replacement components. You will want to measure the spindle in the places where the bearing ride and also the inside...

  • Recommended Jack Stands For Long-Term Trailer Storage To Protect Tires
  • The best way to preserve your tires is to put the trailer up on jack stands, partially deflate the tires and protect them from UV rays which shouldn't be an issue in garage storage. As a general rule of thumb, trailer tires should be replaced every 6 to 8 years regardless of wear. Even though an older tire might appear to have plenty of tread left on it, dry rot and cracking can cause tire failure. You mentioned age not being the issue, so the only cause of separation is misuse or manufacturer...

  • How to Determine the Replacement Hubs for a 2002 Magic Tilt Trailer
  • To determine what the correct replacement hubs are for your Magic Tilt trailer there is a little bit of information that we will need. We will need to find out inner diameter of both the Inner and Outer Bearings as well as the inner diameter of the Grease Seal. To ensure that your current wheels are compatible with the hub that you get you will need to make sure that you also have the appropriate bolt pattern on your hub. If you remove one of your current hubs you should be able to see...

  • Hub and Parts Replacement for Dexter Axle
  • You can use a different bolt pattern as long as the bearing numbers are the same. The easiest way for you to identify the replacement parts you are going to need for the hub is by identifying the inner and outer bearing numbers on your old hubs, which will be stamped directly on the bearings themselves. You would also be able to do this by measuring the spindle to the thousandths of an inch by using a digital caliper such as # PTW80157; you can use the attached photo as a guide for what...

  • How to Select Replacement Grease Seals for Boat Trailers
  • Thank you for the grease seal part numbers you provided. I was not able to find a seal cross reference for these so to select replacements your best bet is to measure your spindle diameters and hub bores to get the required inner and outer seal diameters. Use a precision digital caliper like # PTW80157. Then use the linked page and simply click on the filters for your inner and outer seal diameters to see the options in that size. You can also click on your preference for single- or...

  • Using Brake Adjustment Tool on Drop Axle
  • The # W80630 brake adjustment tool we offer is two sided. One side has a 90 degree bend in it that makes accessing the brake adjuster on a drop spindle much easier. The # W80630 tool will work just fine for you.

  • How to Measure Hub Bore to Find Correct Size Bearing Buddy Bearing Protector
  • To find the correct Bearing Buddy grease cap for your Rockwood camper trailer you can measure either the hub's bore (please see linked photo), where the grease cap installs, or you can measure the existing grease cap's outer diameter. The hub is a more reliable place to measure since a grease cap can be deformed when it is pulled from the hub. This measurement needs to be very precise - to three one-thousandths of an inch, such as 1.234-inches as an example. We offer a cost-effective...

  • Solar Panel Charger that Could be Used to Charge Stored RV Battery
  • If your batteries are all wired together in parallel you could use the Solar Panel charger part # PTW2997 which can give up to a 2.5 watt charge in sunlight. It wouldn't do much but it would keep a charged battery topped off if you had sunlight.

  • Recommended Jack Stands to Elevate Boat and Trailer for Storage with Weight Off Tires
  • For your boat trailer, to keep the weight off the tires for storage, I recommend the 2-Ton Jack Stands - Qty 2 # PTW41021. Each jack can hold 4,000 lbs, but I recommend using 4 of these spaced as evenly as possible to keep the weight off the wheels and then just use the trailer jack for a 5th point of support and balance.

  • What Does the Brake Spoon # W80630 Do
  • The brake spoon part # W80630 that you referenced is designed to adjust the tightness of brake assemblies so that they operate as they should. As long as you have drum brakes on the axle you are referring to this product should work well for you. Check out the video (see link). Beginning at the 4:23 mark, our installer shows how to adjust your trailer brakes.

  • Will the 2.5-Watt Solar Battery Charger Part # PTW2997 Overcharge a Battery
  • I spoke to my contact at Performance Tool (PT) and they informed me that you should have no concerns with the 2.5-Watt Solar Battery Charger part # PTW2997 overcharging your trailer battery. The battery charger has a built-in mechanism that prevents the unit from overcharging.

  • Initial Adjustment Of Electric Self-Adjusting Brakes On Trailer
  • We find that at times the self-adjusting brakes need to be manually adjusted the first time when they are installed. You can do this by going to a parking lot with the trailer attached. Then drive the trailer in an empty parking lot and apply the brake a number of times to get the proper adjustment. To initially adjust the brakes, you will need to raise the trailer and secure it on adequate capacity jack stands. Check that the wheel and drum rotate freely. Do not lift or support trailer...

  • Why Not Set Trailer Aligner # PTW1276 Balls So that They Touch When Aligned
  • The problem with having the balls touch when they are lined up perfectly is that you'd have to mount the two pieces of the part # PTW1276 so close to the ball on the ball mount and the front edge of the coupler that it might interfere before the balls were able to touch. What would most likely happen is the that coupler would hit the base of the ball mounted on the truck and push it back before the balls would touch. That's why they are best to be used as a way to get the left and right...

  • How to Measure Hub Bore to Select Correct Bearing Buddy Grease Caps
  • Bearing Buddy grease caps are selected based on the hub's bore diameter. Please see the linked photo. This measurement needs to be taken using a precision caliper like # PTW80157 to the nearest thousandth of an inch, e.g. 1.234-inches. (We have about 60 different hubs for 3500-lb axles so this is why you'll need to measure). Once you know your hub bore diameter you can use the linked page to select the Bearing Buddy grease caps to fit them. Note that some hubs have a threaded bore while...

  • Locating Trailer Bearing Kit for 1995 Coleman Cedar Pop Up Camper
  • In order to determine the correct bearing kit you need for the hubs on your 1995 Coleman Cedar Pop Up Camper, you will need to pull a hub and check for the bearing numbers. The numbers should be stamped onto the bearings themselves. If you cannot locate or read the numbers, you can also take a few measurements along the spindle where the bearings sit with a digital caliper like # PTW80157 (see attached image). If you are able to tell me these measurements, or the numbers that you find on...

  • Can You Find Bearing Sizes Needed Based On Vin Number?
  • Unfortunately most manufacturers of trailers like your EZ Load do not keep the complete list of parts based on VIN. The best way for us to ensure we get you the correct bearings are to pull your hubs and look at the bearing numbers printed on the face of the bearing. The next best way is to have you measure your spindle where the bearings sit with a digital caliper like # PTW80157 and take some pictures for us. The sizes are very precise, so that is the best way for us to help you get...

  • Adding Electric Brakes To ShoreLandr Boat Trailer
  • I did some research on your ShoreLandr trailer and found it has a weight capacity of just under 3,000-lbs. To add electric brakes to your trailer I recommend part # AKEBRK-35R-SA for the right hand and part # AKEBRK-35L-SA for the left side of the trailer. These assemblies have a 4-bolt brake mounting flange pattern. For a hub and drum I recommend part # AKHD-550-35-K. This hub and drum assembly includes Inner bearing (L68149) and race, outer bearing (L44649) and race, grease seal,...

  • Selecting Replacement Grease Caps for Harbor Freight Folding Trailer
  • I reviewed the online parts list for the Harbor Freight folding trailer 62647 but no specifics are provided for the grease caps required. This is not uncommon for bargain trailers, which often use unusual parts combinations. You will want to measure the hubs' outer bore to determine the size of grease cap you need. This measurement needs to be very precise to ensure a good fit. You'll need a precision caliper like # PTW80157 to measure to the nearest thousandth, e.g. 1.234-inches. Then,...

  • How to Measure to Determine Replacement Grease Seal for Vintage Trailer
  • I linked our main page for trailer grease seals which has filters that allow you to select parts based on dimensions and other features, such as single-lip or double-lip types. We do not offer any seals with your exact inner and outer dimensions. If you can, re-check those dimensions using a precision digital caliper like # PTW80157. It is best to measure the spindle and the hub bore rather than the original seal part since the seal can become distorted with age and wear. The seal...
