Kracher HD801B pressure washer

Hi

The HD801B is making a lot of noise, dismatling the pump and running the motor with only the gearbox on its ok. Can you advise if I need to look at replacing the bearing, and at the same time the gaskets and piston bushes etc. Do you supply a kit for the pump end over haul?

Thanks

HI Robert

can you tell me if the bearing race( blastic ring with ball bearings) is intact?
are the pistons ends intact?
if all looking ok it may be a bypass noise comming from the pump head its self, they can sound very loud (like there about to blow up). when they are just simply blocked.
my advise would first to reassamble the piston guidance fill with oil, leave the pump head off and then run the motor, there are 2 self tapping holes in the piston housing that will hold the guideance in place, then see if its still noisy

Hello Steve

The bearing race is intact, I'll reassemble and test, do you have a blow-up diagram of the pump as I'm not sure where these parts are?

There is a gap at the bottom of the pump assembly between the two pump halves where the oil pours out, I think the previous repair left something out as the oil pours out through the gap in the casting, that's why I suspected the bearing failing as it must have run dry for a while. A diagram would help if you have one on the web.

Many thanks

Robert

Hi Steve

I've found a diagram for the HD801B, I've aslo assembled the pump, run it only to find that bearing 5 in the diagram (part 6.401-332.0) has failed damaging the end of the shaft 13 (part 5.471.088.0) and I suspect oil seal 4 (part 7.367-018.0) also damaged. Can you asdvise how to get the housing (part 5.039-146.0) off the motor as it seams to be a press fit?

I'll need to replace bearing, oil seal, o ring, shaft and cheese head screw, any other parts I should replace?

Thanks

Hi, Robert. once the 4 bolts that hold the housing onto the motor it should pull off, there not pressed on, the parts needede can be ordered from http://www.cleanstuff.co.uk just place the numbers into the search minus the dots and dashes and the last 0.

please check the conection on the end of item 6 (swash plate) this should be bolted to the end of item 13

Hi Steve

I needed the machine sooner so I've taken it to the shop, which was closer than I expected in Stanmore.

THanks for your help in this.

Kind regards
