Lds 426-2 ip

I saw that someone on the board got one of these and just wonder about the interchange. It looks like a late code G pump and that I believe acording to the TM's has the HH that was oil lubed. If that is correct then this lower unit could not use the newer head without the oil block off kit. The HH also could not be taken off and used on the newer lower unit as it would need the lube oil and no passage is on the outher lower unit IP. Thoughts?

humm... what is better lubed or not? common sence would say any mechanical part lubed is a good thing. i have a general idea how the IPs work and know the fuel needs to have lubrication propertys, but does that have anything to do with this lubed and not lubed IPs that you speak of?

Still reading about the specs of this pump and if it puts out a bigger CC of fuel.
Just trying to find out more and learn .What truck would this have been in?

LDS 427-2 engines were used in M35A1, M275A1, and other M44A1 series trucks from about 1960 to 1964.
the oil under pressure does not only lubricate the fuel plunger, but also helps keeping fuel from leaking past the plunger into the lower part of the injection pump.
i do not have the TM here, so i don't know how parts interchange.

James, are you refering to a "newer" model HD9065A replacement head WO/ oiling passages? Are they even available?

In case you mean the original AMBAC heads lately offered (HD90100A), see what I found here regarding interchange: http://www.steelsoldiers.com/deuce/62682-m35a1-lives-finally-vid-link-event.html#post742227

so are any of the LD/LDT-465 IP's oiled in this fashon? I looked a little bit in the TM and didnt see anything. All of the IP's have a little different specs, so i ofted wondered what was the best IP they put on the multifuels. you know, some have droop screws (which i think was only turbocharged engines), some had some kind of oil filter on the pump itself, etc.

Good info thanks Gringeltaube. No have not seen any of the 9065A yet.
Wildchild from the little reading I get they were only on early and late code G pumps.

Thought one of the pumps gave a bigger shot.
