We have owned our Cat 318BL for about 4 or 5 years & need to do an engine rebuild on it, planning on getting a long block from someone at an industrial engine shop to rebuild a long block for us. Our machine ser # is 3LR00468 & believe the machine to be about year 2000. Who knows if it has the original motor in it & the motor shop asked about supplying the original machine ser # for the motor itself. Is that possible for someone to on the fourm to check records to see what engine ser # came with it out of the factory, say on SIS? Engine is a 3046T in the unit.
May have serial number 1/: inside cab below the seat. 2: engine block on turbo side below the manifold near the front ( radiator end). It will normally have the engine number there. 3: by the rams on the cab?
This is the only tag I could find on the engine by crawling around the top of the engine compartment. I never looked in the cab below the seat, but the only tag by the lift rams is the model & ser # of the machine itself. I can look in the cab next time out.
Engine S/N for 3LR00468 comes up in the “as shipped” consist as 5XK26356. Someone may be able to post a screenshot but I’m only working from a phone.
I went back out to the machine & looked at the bottom of the seat; found this tag at the base of the seat. Numbers for what I believe the engine ser to be are: 5XK26356 162-6268. Does that look like a good number? Looks like your are right Nige!
It helps a lot when you know the number you’re looking for.... 162-6268 is the engine Arrangement Number.
Cut the oil filter apart...…….not good!!
Well you did say it was going in for a rebuild! So I guess it is time.
We have had the rebuilt engine back for the past week or so (long block) & finally got a break in the weather today to drop it in. We used a reputable rebuild company to supply us with the long block & we sent our core back & received full credit. After the engine was in we found one slip up, where the rebuilder forgot to tighten one glow plug & it blew out, after running for about one minute! Not good! It did mark the threads slightly, but we were able to thread it back in & tighten it ok. Left it run for about 1/2 hr after we got past the hiccup & so far so good, everything sounds good. They offer a 1 yr guarantee on the rebuild & I made them aware of the glow plug. Mistakes can happen & did..... New water pump, new rad hoses for added insurance. When should we do the first oil change? 30 hrs perhaps? Any special precautions to take for "break in"?
Hi, I normally like to change oil & filter at 50 hours but going on my 320 handbook maintenance changes [not a new motor] @ 100 hours depending on the sulphur content---- if greater than 1.5% by weight ?? then every 50 hours. Initially changing @ 30 hours first off is OK unless you feel otherwise. Filters down my way are cheap $26NZ?? so wouldn't hurt. To me working a machine they deserve to be cared for so hope this helps you.
Believe it or not but the OEM has no recommendations for the first oil change on a new or rebuilt engine. IMHO for a recent rebuild 50 hours would be fine, althougha lot depends on how long it takes you to rack up the hours - you may prefer to change the oil after a certain time. Don't forget to cut the oil filter for inspection when you do the oil change. As regards the "break in" just don't let it lug too hard for the first 20 hours or so.
And I would add to the last don't just let it sit there running with no load. Sure give it a little time to warm up but then put it to work. There is a big difference between working an engine and abusing an engine!
Good point Kshansen working the machine important not just idling
