Hello all, just purchaced a 328 bobcat excavator. Faulty pressure relief valve found which is part#6674259 on bobcat website . is there any place to purchase aftermarket parts? Bobcat online has pretty steep prices. Or place to find spool valve blocks and such used?

Good day
In most instances the spool blocks are manufactured by a third party if you look close there may be a lable or a casting identification if you can post a photo of this we may well be able to help you.

If we can establish the manufacturer of the block we can then try to source alternative parts we are reasonably sure the block is KYB please take a look at attachment.

Thks for the reply. I will attempt to find some markings. What i find disturbing is that when searching for pressure reluef valves many come up for different machines. And all of them reasonably priced. 50-150 bucks. The one i need cant be found anywhere and is way more than that.

Before you go down that street please what is the problem with the valve you have ?
Ok...salt water has rusted this machine badly. The pressure relief valve in question, part# 6674259, is rusted through and leaks profusely. Even while not under pressure and machine off. Ths spool block is a 7 section (5 spool) assembled block. It all dismantles and held together with 2 tie rods. I am posting pics from machine and from bobcat website. Relief valve #12 on diagram is the bad one. It can be located on bobcat online parts under ------300 series 514013001 & above-----, control valve(5 spool). I will try to locate a part stamping but due to it being individual parts i dont think i will be able to. I hope this expains it well. Also....i can find the part right from bobcat but i am absolutely blown away at the high cost for such a common and simple pressure relief valve when most others are 6 times less cost. I fear i may need more valves (rusty spot) . And at these prices it will cost me $10,000 to rebuild a spool block for a 3 ton machine. Just frustrated!!!!!!

Like you have mentioned....possibly i could cross reference the valve to an after market one or factory direct or something like that and i figured the original part number would do but so far nothing. Also figured i couldnt possibly be the only one who has needed this valve and hoped someone had a line on them other than bobcat.

Good day Ft
I can see where the valve is have you a picts of it out and dismantled ? That is certainly rusty has it been swimming in the sea ?

Ya hahahah it looks like it was swimming. If u saw all the pitting else where u would have no doubt it was swimming. Anyways i did not dismantel it yet. Hiring a mechanic to do job. He has more experience than i and considering that i had to sell my first born child for the part i want to make sure this goes as smooth as possible.

From what we can see we feel sure the block is of KYB make or copy, what is of concern if the valve is leaking from the seals if that is the case it could require a minimum of the inlet section replacement.
In your shoes I would be inclined to remove the complete block split it down and make a thorough inspection or you could be chasing a chain with many broken links. See illustration of two tie block.
The format is not uncommon used an many of the Mini -Midi machines may be find a better one at a breakers.

I refer to "Breakers" as dismantlers in some case's machines become uneconomical to repair which are then dismantled and sold as spare parts, it may be worth checking if the valve chest is common to the other Bobcat models (Check part No. with a dealer) you can then make a search on the internet specifying the different models. You can often see such parts for sale on the likes of Ebay ect. I would be some what concerned you have a money pit on your hands as that kind of damage surely is not just isolated to the valve chest.
I hope you find my advise helpful and constructive but it would not be prudent that I ignore the likely outcome.
Kind regards

Thank you so much for the advise. Yes i too have been pondering the same. What is keeping me in the game is the unit shows very little hrs -1200ish. Meter appears to be working Yes it could have been changed but it purrs so nicely. Maybe i am being decieved.

A few of the guys I have contact have been caught in the same trap a couple have turned a negative to positive by dismantling the machine and selling the used parts, one told me he doubled his money. Food for thought maybe.

Well sadly i ordered the part i need. Very expensive and really a sad testament to the poor service after the sale for bobcat . When things are that expensive to keep running its a surprise that people would buy one cuz things break from time to time. And whether for personal or business use the bottom line is the same........higher running costs. I am putting machine together and good chance its going up for sale. Thanks for all the help uffex!!!
