Looking for a hydraulic head for a M35A2

[PaFarmer]

My piston is sticking again. I removed hydraulic head once before and after cleaning it ran fine, but now months later the piston keeps sticking. All the big vendors that pop up on a google search or out of stock.

Hello Frank.

I have a very good used complete fuel pump assembly including timing gear for a reasonable offer.
Is clean ready to install.

I did a little digging and note that the Chinese manufacturer is still offering these.
They are made by Chinahanji and are a drop-in for our PSB6 AMBAC pumps.
Old threads exist here; for a while these heads were on eBay. They have been looked over by people that know this stuff and found to be well made and, in details, improved compared to the original.

I have zero affiliation or trade interest. I do, however, own one of these HH, installed in an LDT engine.

If you are in dire straits and need a factory new HH for the LDT-465 engine, here is the contact info that I found:

Read some of the older posts from around 2010 with regards to these and also the nozzles; the nozzles also work well, provided they send the correct ones!

This may or may not help, but some people have a spare engine for parts, so you may wish to expand your search and look for a complete spare engine.

When I found a spare engine, the whole was less than what people charge for the pump.

Just an idea.

Not sure where to plug this ...been years since I've been in SS.....I'm in great need of someone to help me " correctly" time a HH, ....I've tried one method I was given just find out it was incorrect.....I do not have a TM, I am a diesel tech. for a railroad so I'm not totally stupid to these thing but this one is pissing me off if you can help or lead me in a direction I'd appreciate it.
Thanks.

Hey Nick!
The TMs are available for download free on this site. I did so many HH replacements at one time, I could do them with one hand tied behind my back, blindfolded, underwater, at night. But the last was almost 10 years ago, and I've slept since then so now I forget.

I recommend downloading the TM and printing off the pages you need. There is a bit of a trick to it, but if I could figure it out, anybody can.

This is what you are looking for:

Injection Pump Timing

Thanks to Gimpyrobb aka Chris. There is the easy way to find correct TDC on the harmonic balancer than taking off the valve cover if we are just checking timing. Take off the oil fill cap and look for the valve that is just forward of the fill hole. You should just be able to see the #2 exhaust...

I ordered and received two hydraulic heads from Lutong. they were $142 each and came to about $200 each with shipping. Took about 2 weeks. No hassles. They look good. I will get it installed this weekend.
