Perkins 4-154 Injector Seals

[SV Demeter]

Im trying to source a set of spare injector seals for my 4-154. These are the rubber seals that go between the injector and the head. I tried TAD in Virginina and Sheri told me:

The injector rubber seals are no longer available from Perkins.

I see that one on my engine looks like it is close to failing but I dont want to take it apart if this is going to mean the death of my diesel.

Try Foley's in Massachusetts or any tractor dealer.

Post where you find them. I would like to buy a set for mine

So far not ha ving much luck. Foley emailed back quickly asking if I was looking for the copper washers that seal the injectors to the head. I replied no I am looking for the rubber ones that look like a big O-ring or rubber donut. No further response. Im going to work on the boat tonight after work and will try and take a photo to send the guys at foley. If these seals are as critical as I think they are and I cant find a replacement/spare Im thinking im sorta F*#^ed! Cant believe I would have to replace this engine with ony 2k hours on it because injector seals are NLA but I was warned about the trouble in finding parts for the 4154...

Injector shops usually carry seals. Are you sure they are not copper like the 4108?

Is your Perkins American or Japanese?

Part #0920113 injector washer. it is an O-ring...but any vi ton O-ring of that size will work. O-rings are easy to get. check with your local Diesel shop, they should have something that will work .I'm looking for a engine kit myself, please keep us 154 owners informed on your search....Ed

This photo shows the seal, its orange. It does appear to just be an o-ring. I guess Im not wondering jsut what it does if the copper washers are in fact doing the sealing job. I suppose the ting to do will be to remove one and measure it then try Mcmaster or others. I sent the photo to Foley to see if they had an "Alternative" solution if this partis in fact NLA.

I have a 4-154 aiso and do not have these seals, I do use the copper seals and just had the injectors and pump reuilt. I am having an overheating problem now and the cooling system is clear. I have heard the injectors can cause overheating, could your seals stop that problem?

[SV Demeter]

I would not think these seals would impact cooling but I do think injector timing can impact operating temp.I have not had any cooling issues yet... I would check your exhaust for restrictions and carbon build up, esp in the mixing elbow. Another thing is to flush the heat exchanger with acid but you want to be careful doing that.

Huh? E.P. I've got a 4-154, too (1983) and it doesn't have those seals. I recently pulled the injectors and had them serviced--just gooped them up good with anti-sieze (that P-Tex product) when I put them back in and they have worked great (knocking wood, knocking wood, kocking wood). Here are two guys in Florida that are worth a call.

Diesel Injector Services/Riviera Beach, FL: (561) 844-8999. These are GREAT guys to work with-very straight up and knowledgable as well as affordable.

Complete Yacht Service/Ft Liquordale, FL: (954) 462-6977. These are Perkins dealers who helped me get some parts. Have your serial # ready and they should (hopefully) be able to help or offer an alternative.

GOOD LUCK!!

I took a look at my 4.154 a few days ago & it does have some sort of rubber seals under the injectors

[Mark Zarley]

Lehmans have a similar seal, it is only available in the complete gasket kit.

At this stage I am really wondering what if anything these particular seals even do. The more I look at the one that is failing the more it looks like just a ring cut from a piece of rubber hose. I would like to know just what is its purpose?

They could be a silicone compound for heat distribution/conductability or insulation.
