L1501 - L185F core plug replacement

[thespanishfarmer]

Hi all.

When using my L1501 a few days ago, I noticed that I had a few drips of water leaking from some where on the left side of the engine block. Using it again today and the few drips had become a lot worse. I stopped it right away (well after getting back to the tractor shed) and removed the alternator and starter motor to get access to where the core plugs (or freeze plugs) are situated. The front one has a hole in it and needs replacing.

Three questions if I may please.

1. First and foremost, what is the technique involved in the removal and replacement of the core plugs ? I don't want to just start banging around with a screw driver and hammer !!!!)
2. I noticed when researching the forums that a previous semi related thread had quoted the part number 15221-03383. The Kubota parts list I have shows part number 15221-03380. Does this make any difference to the actual part ordered ?
3. Given I have the correct part number, how easy is it for me to obtain a new set of three core plugs ? Messicks wont deliver outside of the US.
I will be contacting the supplier of my tractor here in Spain first but if I have no joy there, I will have to try and start sourcing them from elsewhere.

As usual, any advice will be gratefully received.

Personally I dont think that you will have a problem getting replacement "core or freeze plugs." If you do not have success in getting them from your tractor dealer look to an auto parts store. These are not really Kubota specific technology. Only critical bits is the diameter and flange height. although several different flange heights should work. I myself have not changed a plug on one of my kubotas, I have on other engines. On those, I tapped on one side until I could get leverage under the plug and worked it out. clean the hole in the block of any built up crud. Place the plug against the hole and using a socket similar in size to the plug tap the new one in. in the beginning it may take more of a tap to get started. thats pretty much it. Just hit where your aiming with the hammer. Dont slip and break something else by accident. Thats my process, i'm sure others will have there own way as well.

Hi Kytim.

Sounds like good advice to me - thank you. Of all the years I have worked on different types of engine, I have never needed to change a core plug.

I will just have to wait for the dealer to get back to me now.

Gary,

Whenever I have had to replace a freeze plug, I have always used a punch or a screwdriver and hammer to knock one side into the hole then grab the plug with a set of pliers to pull it out. It doesn't take a lot of tapping to get it loose.

A socket that fits inside the new plug works for a driving tool to install them; although a bearing and race installation tool works also. I have always stopped driving the plug in when the flange is level with the block, and never had any leaks.

Thanks Robert.

I managed to remove the plug today by 'gently' tapping with a punch and screwdriver and then pliers. I was speaking to a friend down the road later today and he told me (too late) that the best way to remove a core plug is to drill a hole in the centre and screw in a large (fat) self tapping screw and then use a claw hammer to lever it out by the screw. This way, the pulling of the screw contracts the plug in the centre and it is easier to remove - food for thought if I need to remove one again.

The supplier has emailed me back and states that the tractor is still covered by their warranty and he has put a new plug in the post for me.

I have measured the old plug and it seems to be 32mm. They are available on ebay (UK) for not a lot of pennies for a pack of five. I will measure the new plug when it arrives and then get a batch in stock just in case.
If I don't need them, they will be handy ashtrays in the workshop!!!

Cheers guys.
