Removing, rebuilding, reinstalling Hydraulic Head

[skywrangler]

This is a great thread! Read the whole thing and study the pictures. One question though since I have not seen this issue here or elsewhere. The 3 armed retainer for the button on the HH.... Is it supposed to have 2 or 3 clip parts that hook over the edge. Mine only has 2 and I suspect there are supposed to be 3. While the 2 remaining hold the the button in, it probably is not correct and one of the arms has broken at the bend to form a third clip.. Am I correct that there should be 3 clips fitting over the edge and not 2 to hold the button in? thanks, Scott

Ok in reviewing this thread I now see from the 3rd image, page 1, 3rd post, that the button retainer indeed does have 3 clips, one per arm... darn... mine only has 2..... Clearly the clip has been shed... God knows where it is and what consequence there may be.... Any suggestions? Parts source??? would seem crazy to buy a $1000 remanufactured pump for one part.... thanks... Scott

The search engine here is great! After searching "button" it seems the button retaining clip is an issue...

I believe some guys were getting them from Ambec. I can't say for sure though.

Hi, Ambac is the place to order that from. The contact person is Melody Feaster at Phone: 800-628-6894

The part you need is a RG 902 retainer. It is only a few dollars....I just bought a couple recently...... Good luck

I think that you're the first person here I have ever read saying that.

Thanks for this thread. I am helping a friend who bought a used duece that was ran on fryer oil and the plunger is stuck . the bottom button looks rough and scored . It fell into the pump when I pulled the head . I got it and the retainer out with a magnet .Does Ambac have the button as well ?

Pulling out my HH tomorrow for new gaskets. This thread has been a HUGE help to me. Big thank you to all involved!

 

[scboolitcaster]

The gasket for the fuel shutoff cover (I think it's official name might be the timing window cover) looks like some kind of wire mesh.

Mine needs replacing (broke). What material do you guys use for those? It looks like I could get one from Oshkosh but I'd rather not pay 10 bucks + shipping for a little gasket. Plus I want to put it back together this afternoon.

It holds back oil when all is well I think.

There little to no pressure on it. I would think a roll of gasket material and making your own should be fine.

That's what I'ma gonna do. The TM calls for a gasket .020 thick, which is a replacement for one .031 thick.. So I'm buying some 1/32 Karropak from o'Reilly.
It also calls for the equivalent of Permatex #3 gasket sealer. But I want to be able to get it apart again, so I'm going with something a little less adhesive.

ok hi. im sure this has been asked on here before but i am at work so i dont have time to read through everything, but i need help. my plunger broke on our deuce, i need a part number and place to purchase that along with what i believe to be the button. i had gotten the part number for the retainer, so im good with that. also is there any place to buy the o rings needed instead of trying to find somewhere to go that actually knows how to look o-ring sizes. thanks in advance for info. much appreciated.

I'm not sure if you can buy them from Ambec or not. If all goes well DHL will be delivering me 5 new units on Friday. If interested let me know.

 

[nadeau191]

how much for a unit??

 

[kennys@wi.rr.com]

When they get here I will see what size flat rate box they fit in and post it as a sale ad then. No need to upset any of the mods by listing parts for sale in a regular post.

I got my hands on two trucks last weekend, one is running great, drove it home, the other won't start, hydraulic head was stuck. Found the clip, it's ok ad the button has one little ding on the edge and I already stoned it. The plunger guide is broken and I'll order a couple in am, my question is what is suppose to be under the 12 point plug on the side?

 

[kennys@wi.rr.com]

Think of the star bolt as a plug that you don't play with.

If you need a head for any reason let me know, I have a few new heads left.

 

[texas30cal]

Too late, my buddy pulled it before I got there, there was only a spring under it, is that correct?

 

[kennys@wi.rr.com]

A Spring, a check ball and a crush washer as I recall.

 

[texas30cal]

I got it all cleaned up, there is the 12 point plug that uses a tapered seat to seal against the hyd head, then a spring, and it was stuck pretty good but in the bottom of the hole is a pointed needle valve similar to what's in a carburetor except it is steel , any of this sound right?
