for the third year I use this kit
Perfect

1st overhaul for me of the engine with replacement of filters and turbine received quickly and replacement nikel I recommend this product

It was nice to be able to buy all the service parts I required without searching for part numbers

Very useful

Thank you for the quick forwarding of the kit to the marina and not to my home address

Is not installed yet.

everything went well, only that the oil filters are smaller than the originals of my engines, the attacks and the rings were identical. I hope the difference in size doesn't cause oil circulation problems

Product corresponding to the request, fast delivery....
I recommend......

no complaints

So far so good. The impeller does not have the wear tones on the end faces and has a few fewer fins than the original. Yes, the dimensions are correct, but the execution is very simple as a replica. The filter actually comes from a manufacturer, the thread and seal diameter also fits, but the overall diameter (housing) is significantly smaller (min. 10mm) and also shorter in height. I will NOT mount this for the Bay of Biscay and the Atlantic! Baltic Sea for later, no problem but not for the transfer.

For engine maintenance.
Kit is listed wrong with you so far. But you have already reacted.
I received a corrected, different order without impeller and seals properly.
It's all ok.
Many Thanks

Oil Filter not compatible with my engine

The impeller is just a little too high, making it difficult to put the cover back on. The original from Yanmar only has 9 blades, the part here doesn't fit!
The paper seal supplied is unusable. The holes are in the wrong place.

Oil filter too small, diesel fine filter has no opening for the water sensor, impeller quality is questionable, it is full of residue from the injection molding tool.

The diesel (fine) filter (H173WK) included in the service kit has exactly the same dimensions as the original Yanmar oil (!) filter and fits EXACTLY on the oil filter housing of the Yanmar 4JH4EA, both in terms of the diameter of the sealing ring and the thread of the screw connection!!

On the other hand, the oil filter (H97W06) included in the service kit is only half the size of the original oil filter.

The description of the service kit lacks a clear list of the Hengst part numbers indicating which filters are included. Furthermore, the impeller included in the service kit looks very cheap. Rubber flanks are leftover from production and must be laboriously removed to avoid them eventually ending up in the heat exchanger.

A resounding NO to this service kit and my sincere disappointment to SVB, where the quality should be checked more closely!

These are not the filters for the 4JH4...
