Atlas Air/Hydraulic Pump with Plastic Reservoir This is a power unit, not a tool. It takes an existing hydraulic cylinder that is currently raised by hand or by foot and converts it to air power: shop air goes in, up to 10,000 PSI of hydraulic pressure comes out, and the operator's hands stay free. Atlas lists it under part number ATEHTTLA5100, it is the featured power unit on the Atlas "Hi-Rise" motorcycle/ATV lift, and it is the replacement pump for the Atlas HT1005 motorcycle/ATV lift and for many of the Atlas rolling bridge jacks. That last sentence is why most people are reading this page. A pump has stopped building pressure, or a jack that was fine for years now takes forty strokes to get a wheel off the ground, and the question is whether the machine needs replacing or just the thing that pushes the oil. Usually it is the latter. What it actually changes The cylinder, the ram, the frame and the lifting geometry of your existing equipment are untouched. All that changes is how oil gets to the cylinder. Instead of a lever or a foot pedal driving a small piston by muscle, a compressed-air motor drives the hydraulic section for you, and a foot pedal becomes a control rather than a source of effort. On a rolling bridge jack under a four-post lift — where you are already crouched, already reaching, and already holding something — that difference is the entire job. The rated hydraulic pressure is 10,000 PSI. That is the pump's ceiling, not the pressure your cylinder will see in normal work; it is headroom, and headroom is what keeps a power unit from being the weak link when a cold cylinder is stiff or a load sits badly on the pads. Will It Fit? This unit is small enough to mount almost anywhere on a machine: 12" long, 7" wide, 4" high, and 22 lbs on the shipping scale. Before you order, check three things against your equipment and your shop air: Air supply. Working pneumatic pressure is 90-175 PSI. Any reasonably sized shop compressor covers that range, but a small pancake compressor that struggles to hold the bottom of it will make the pump feel slow — this is an air-driven unit and it is only as good as the air behind it. Air inlet. 1/4" (1BNPT). That is a standard shop-air fitting size. Hydraulic outlet. 3/8" (1BPT). Your hose or hard line has to land on that port, and this is the connection people get wrong when they are adapting a pump to a cylinder it did not originally ship with. Reservoir capacity. 200 IN3 of useable oil — a little under a gallon. A cylinder with a long stroke and a large bore draws more oil than a short one, so if you are converting something that did not come with this pump, confirm your cylinder's displacement is inside that figure. Those four checks are the buyer's responsibility, not ours, and they are worth ten minutes with a tape and a thread gauge. If you are unsure whether your cylinder is a match, send us the model of the equipment before you order rather than after. The plastic reservoir is a deliberate choice Reservoirs on power units of this size are usually steel. This one is a heavy-duty plastic housing, and the trade is straightforward: it keeps the unit light enough to carry one-handed and to bolt onto a rolling jack without adding meaningful weight to something you push around a bay all day, and it cannot rust from the inside when condensation collects in the oil — which is the way steel reservoirs on air-driven units normally fail. Steel takes an impact better. If your unit lives on a bench in a busy shop, that is worth knowing; if it lives on a jack or a motorcycle lift, the weight saving is the bigger deal. Foot-pedal operation The control is a foot pedal, which sounds like a detail and is not. Lifting a motorcycle or an ATV is a two-handed job — you are steadying the machine while it comes off its wheels. A pedal means the pressure control is on the floor where your foot already is, so nothing about raising the load requires you to let go. Perfect For Owners of an Atlas HT1005 or an Atlas rolling bridge jack whose original pump has failed — this is the direct replacement. Home garages converting a hand-pumped jack or press to air, where the shop compressor is already in the corner doing nothing between jobs. Commercial shops that want the same lifting equipment to stop being the slowest part of a wheel-off service. Anyone with a cylinder and no pump — a salvaged press, a shop-built fixture, a machine whose power unit is long discontinued. What's in the Box Our data sheet for this listing covers the air/hydraulic power unit itself with its plastic reservoir. It does not itemise hoses, fittings, mounting hardware or hydraulic oil. If your conversion needs any of those, ask us in writing before you order rather than assuming they are in the carton. Specifications Type Air/hydraulic power unit, foot-pedal operated Rated pressure 10,000 PSI Working pneumatic pressure 90-175 PSI Useable oil capacity 200 IN3 Hydraulic outlet 3/8" (1BPT) Air inlet 1/4" (1BNPT) Overall dimensions 12" L x 7" W x 4" H Reservoir Heavy-duty plastic Shipping weight 22 lbs Listings and approvals, stated honestly The product data we hold for this pump records no third-party safety listing or independent laboratory approval, and we are not going to imply one it does not claim. That is not a defect — power units of this class are frequently sold on the manufacturer's own specification — but if your insurer, your employer's equipment policy or a local inspector requires documented third-party approval on shop equipment, ask us in writing before you buy and we will tell you what documentation exists rather than guessing on a product page. Shipping and Delivery Shipping is quoted live at checkout for your address in the lower 48 rather than baked into this page, because carrier rates move. At a 22 lb shipping weight and a 12" x 7" x 4" carton this is a parcel-sized item rather than a crated freight shipment, so no forklift, no appointment and no unloading plan is needed at your end. Warehouse pickup is available from our Atlas locations if that suits you better. Whichever way it arrives, look the carton over before you sign for it and note any damage on the delivery paperwork at the time — a note written on the receipt is evidence, and a phone call the next day is not. Warranty This listing does not publish a warranty term, so we are not going to state one. The claims process and current terms are on our warranty claims page, and if a term in writing matters to your purchasing decision, ask us for it before you order. One thing that applies regardless: if a pump fails, do not open it up before you have started a claim. Disassembly is the single most common reason a legitimate claim on a sealed power unit gets refused.
