Cam shaft bearings are seized in Dewalt DPD3100 presure washer. does anyone know where to purchase the roller bearings. can not find a part number, do not want to purchase new pump

take the old bearing to a bearing retailer and the number on the bearing identifies it so you will get a new bearing from them (CBC, Timken,SKF )

Remove the rocker cover to ascertain the damage done . It may not be bearings but seized valve in the head. To fix cam bearings properly it may necessitate the head removal and machining both the head surface and then the bearings should be line bored to realign the cam shaft correctly. Some Nissan products have the cam bearing housings adjustable with shims to align the holes correctly and if not done will break the cam shaft. IT may be the cam shaft is broken and jammed . What ever it will not be just a case of putting in new bearings until you have the head and bearing alignment checked out by an engineering shop.

see if it has a low oil shut off and the oil is just at the level

Remove Items 122 (Un;loader) and 138 (Thermail relief). Clean them up as best you can with a nylon brush under some slow running water. Dis-assemble the unloader valve completly to clean (both ends). Then lubrcate them with White Grease and reinstall both parts AFTER placing White grease in the cavity the valves mount into. Very briefly... Test water flow with the engine not running Then start the unit with water off and let run 30 seconds. Turn off engine. Turn ON water supply and test water flow engine OFF. Note you will get a certain amount of white grease initially that passes through the unit. Start unit and rapidly actuate the trigger 1/2 second on 1/2 second off multiple times to force the unloader valve to cycle.

You can get parts here if either of the valves have completly failed:

In the Pump Dewalt recommends
DeWalt DP70 Pressure Washer Pump OilIn the engine Dewalt Recommends
SAE 10W-30 is recommended for general use

Take the hose off the gun and see if water comes out. If so the gun has to be taken apart and cleaned. Also where the water hose goes in to the machine there is a screen filter which you might have to clean if water is not comming out on the gun side. Use a screwdriver and pry it out carefully around the edges Clean the screen with a wire brush and put it back in and try it.

The coupler that the nozzle goes into uses a 1/4" EPDM o-ring. This o-ring needs to be replaced. You can find them at most major hardware stores or purchase them by contact us at 800.247.8103 or visiting www.landanw.com.

Hi

Just try the following steps

• Inspect the water supply connections
• Inspect the drain hose
• Inspect the water pump
• Inspect outer tub for cracks or corrosion
• Inspect the tub seal
• Inspect the tub bearing

Good luck
