Karcher K2.65 Jet washer

MOTOR PLANET GEAR WHEEL Both of the gears were mashed, so needed replacing, cheap fix rather than scraping the unit, but you will need to replace the Oil within the pump housing, this has got to be of the correct type, can’t just use car engine oil, Cost of this is around £17.00 for a Lt, but you will only need about 120ml, lots left over, still better the a full replacement, if you have decent DIY skills this is not a too bad job. What my unit did before I discover what had failed, hope this can help others..? • With water supply on, No leaks seen • When power applied, unit would just run continually • Water spray availably from lance but not under presser

Great product easy to fit

Planet gear wheels arrived quickly and fitted perfectly in Karcher K2 compact washer to replace the mashed gear wheels. However unit still leaking on one cylinder. Can't decide whether to scrap the washer as beyond economical repair (BER) as new cylinder head is £60. when new washer is around £80...... Decisions, decisions!

Refreshingly cheap & easy

Nice to find a cheap single replacement part rather than having to buy a module / set of components. You have to take the motor off to fit them which actually turns out to be straightforward with no hidden springs, escaping bearings or unpleasant surprises. Need to clean out the debris of the old wheels Easy to fit. Just push them into place You do need to lubricate the area though, so need pressure washer grade oil to hand

Good morning. I would like to ask you if this product (MOTOR PLANET WHEEL Part Number: RS823371) is compatible with my washing machine which is Karcher K2.38M.
By ATHANASIOS - ATHENS - 21/10/2019
Hi Athanasios, thanks for your question. There are a few different versions of the K2.38, so we'd need to know the TYP number from the rating plate to be sure. Once you've found this, please fill out a part enquiry and we can look in to this for you.

When assembling the new Motor Planet Wheels, do I need to put some sort of oil in with them. As the old 1s were broken into loads of bits and flakes of plastic inside the pump. The reason I stripped it down was the fan stayed on continuously, once turned on and the inside of the washer casing had some sort of oil all over it.
By Steven - Sunderland - 23/08/2020
Hi Steven, I'm afraid we're unable to offer technical or fitting advice. I'd recommend contacting an engineer to see if they're able to help. Please accept our apologies.
