That 39MT looks like it would of been sweet. Oh well, next time.

The 40MT is in with the help of a neighbor. No way was that going in without help. Had to drop the small pans under the engine and push it up while the neighbor put the bolts in. It cranks fast and in the right direction. Glad thats done.

Well he said $1200-$2400 depending on what it needs, and I just kind of posted the average.

Weather is currently putting a damper on my plans. Hopefully one day I have a shop this thing fits in.
I had one off of my 13x 955L a few years ago by a retired Cat fuel system guy that has been doing fuel pumps for many years and it cost me $800 but his quote was like yours,it depends on what it takes,so I came out lucky too.

It lives! Last night I Finished installing the pump, ran the block heater a few hours, bled everything, and it fired up.

This morning I ran the block heater a few hours again then got to work with it.

It sounds good. Runs strong. No bogging down. Idle sounds smoother than before.

I STILL have to purge air out of the pump each time I start it. It’s sucking air somewhere still.

The fuel pressure gauge is dipping almost to zero when I’m running hard but the machine doesn’t bog down. Most of the time it was between the 11 o clock and 1 o clock positions (see picture).

I’m thinking about swapping my old hand primer pump back on. The new one I got from cat has fuel coming out around the plunger when I’m using it, so I’m guessing thats not right! Picture attached.

Another one of my random thoughts: Should I bleed air out of the line going to the fuel gauge?
I'm thinking this is where you're getting air.

I ran the machine for numerous days digging and loading shale. Everything is back to good.

I lost two bucket teeth and found them with a metal detector.

Current to do list:
- reattach those two teeth
- install new glow plugs and harness
- change engine oil and filter

Thanks to everyone who helped this year. I learned a lot, fixed a lot, and got a lot of work done on the property.

I added a 1937 R5 dozer to collection and now I'm adding another old cat.

A friend hooked me up with a deal on a 1963 44A D6B with a cable blade. Runs and tracks nice. I am getting it next weekend. It seems I have the antique heavy equipment addiction now.

Yesterday was the last warm day for awhile so I retrieved the 955L from the back of the property and brought it up to the house for some maintenance.

Engine oil change was uneventful. I still had the front belly plates off from replacing the starter so that saved time.

No one told me the glow plugs would be so much fun. I had never replaced glow plugs before. Now I know the build up on them makes the stem larger than the hole it went in, but with the help of kroil, vise grips, and patience I replaced them.

Now to tend to the rest of the fluid levels, replace the transmission temperature gauge that quit working, and reattach two bucket teeth that came off.

I did some reading on diesel coolant additive. I didn't know anything about it until I saw it mentioned in another forum here. I have been adding normal green coolant when needed or when I did some work. Does anyone have a recommendation for an additive? Draining and refilling with premixed diesel coolant isn't too exciting for my wallet, but if everyone says just do that then I might have to. I still run a little warmer than I like if I don't keep the radiator blown out and run it in the "sweet spot" of engine rpm.

Post a photo of the coolant container showing what specification it meets. It is likely that different advice would be necessary depending on what the coolant you are currently using actually is.

This is what I buy and mix with distilled water:

  • Free of phosphate, borates, nitrites, silicates, and amines
  • Protects against corrosion of cooling systems metals, including aluminum
  • High-quality defoamer which is non-harmful to hoses, plastics, or gaskets
  • Premium quality, extended life antifreeze/coolant
  • Meets ASTM D3306

G..G..G..Granville.........!! Fetch your cloth.
If it meets ASTM D3306 that is a light-duty coolant, the sort of thing you would use in your pickup truck cooling system for example.
You really need a Heavy Duty coolant that meets the requirements of ASTM D4985, such as the example below. Alternatively have a word with your Cat dealer and ask them what their price is for Cat ELC coolant.

“Next time” u run into gp’s that are swollen like that, spray’m down like u did.. THEN, chuck’m up in a cordless drill and spin it while your pushing and pulling.. it makes short work outta a crappy job..
BE SURE to keep the drill straight, otherwise you’ll snap a gp.. & that’s no bueno.

Called a dealer and 5 gal buckets of ELC are $84.06 - $16.81 per gal.

The Cat ELC is prediluded, right? I found the Cat ELC adheres to ASTM D3306 and D6210, but not D4985.

My local Rural King has this heavy duty option: https://www.ruralking.com/providence-heavy-duty-precharged-antifreeze-concentrate
  • No initial charge of SCAs required
  • Meets or exceeds: ASTM D3306, ASTM D6210, TMC RP329
  • Service life of 300,000 miles | 6,000 hours of offroad use*
That would be the most economical option if it is suitable, as it is cheap per gallon and sold as a concentrate.

For me to reference later:

ASTM D3306: Ethylene glycol based coolant for automobile and light duty service; can be high silicate or low silicate (less
than 250ppm as Si).
ASTM D4985: Low-silicate ethylene glycol based coolant for heavy-duty engines requiring a precharge of supplemental
coolant additive (SCA)
ASTM D6210: Fully-formulated ethylene glycol based coolant for heavy-duty engines; containing a minimum of 2400ppm
nitrite (1200ppm in 50/50) or 1560 nitrite plus molybdate (780ppm in 50/50); does not require an initial charge of SCA.

Note: ASTM D3306, D4985, and D6210 all incorporate the following individual tests. If an antifreeze meets any of these
standards, it also meets the following:
• ASTM D1384: Corrosion in glassware
• ASTM D4340: Corrosion of cast aluminium alloys under heat-rejected conditions.
• ASTM D2570: Simulated service corrosion testing
• ASTM D2809: Cavitation erosion/corrosin in aluminum water pumps

I see a lot more antifreeze these days that specifically says for diesel engines or HD diesel engines. On older machines I'd imagine there wasn't much difference in antifreeze types. Would switching to a newer type on an older machine be beneficial, harmful or not make much difference?
