I really appreciate what you do, Bug. At 50 years old... I am a novice with nitro, and sometimes I end up watching your videos more than once, for sure. There is so much to learn. I need to find your Facebook group!
Hey brother thank you so much for stopping by I appreciate it and I will show you the group. Nitro RC enthusiasts group on Facebook. I'm an admin look for the guy smoking in dark sunglasses 😎 you will see me around. 🤘🏻🍻💯
@thebug 404 Hey Bug! ... I put in my request to join Nitro RC Enthusiasts a good 24hrs ago... and answered the questions. I have not heard back as to whether I will be allowed to join or not. I wanted to make sure I didn't mess up somehow. What should I do?
Nothing wrong with the block on the HPI But the carbraters are garbage they're really cheesy they don't tune all that great from what I have found and that stupid steel sleeve on the bottom will get loose and then your carburetor will spin in the block no matter how much you tighten it down and then it will get stuck in the block and ruin it.
Got my first engine with ceramic crank bearings. PROTEK Samurai R03. Brand new, Spin the crank and it feels like the balls have flats in them. Unbelievable how rough this thing spins. Ran 1st break in tank, tons of oil out the front bearing. I bought the engine in 2020 and just recently used it. They won’t send out bearings as it’s been a while and I get it. But not impressed and not happy.
Could be a manufacturing defect I'm not sure I haven't dealt with one of those engines before but it would probably be a good idea to replace the bearings to avoid a failure.
@@thebug4046 I put the kids to bed and was going to tear down the engine to yank the bearings out. Before I did though I spun the crack back and forth a lot and I’ll be damned the roughness all of a sudden stopped. Turns smooth as silk now. I don’t get it at all. Removed the backplate and nothing fell out. Clean as a whistle. I guess I’ll run it and break it in and if it keeps leaking I’ll install a double sealed bearing in the front unless someone thinks that is a bad idea. But I’m baffled though why it was turning so rough. 🤔
@@Thedudeabides803 keep in mind the bearings don't seal the engine. It will always leak if it's tuned to rich or to much after run oil was used. I have a video explaining it
@@thebug4046 awesome thanks man, I won’t worry about it then. I have run exclusively and many 2.5 and 3.3. Traxxas engines since 2001. Love your videos on them btw. Who knows they were all probably leaking and I just never noticed. First time with a different engine other than a Fantom .18 I had way back. This engine cost me an arm and a leg comparatively so I am monitoring what’s happening with it with a very scrutinizing eye. Cheers
@@Thedudeabides803 Definitely good engines to learn with for sure since there's such an abundance but yeah when you start getting into these hide all our engines shit gets expensive quick! But yes like I had mentioned with the whole front bearing thing they don't seal it's actually a liquid seal between the crank and the inner case of the engine kind of an interesting design really if you pay close attention to how it's designed. Old European rc car on road engines ran without any kind of seal or shield on the front bearing at all! It's a myth that companies came up with to sell you bearing that you didn't need and when you change out your leaking front bearing for a new one that still leaks Leaves you scratching your head for a minute wondering why and all it is running too rich. 😆 but I'm glad you find the videos helpful! 🍻🤘🏻💯
IV got everything for the 4.6 engine a Piston sleeve and connecting rod set new 50$ any parts for it I got the crank shaft I put in a drill and spin it while use a super fine skatch bright pad I it looks brand new every time 👍👌✌️💯🛠️🍻 the internal bearing for the 4.6 is a different size then any other 28 except for the force I'm not positive but I think that's what the f stand's for. The 4.1 3.5 hpi and the sh28 use the same size bearings and crank shaft size but the hpi 4.6 is actually bigger crank diameter just a fyi 👍👌✌️💯🏎️🍻 savage nation 💪
Nice and yeah I was quite surprised at such a strange bearing size for such a common Taiwanese made engine usually they're all pretty similar or almost the same and yeah I have a new piston and sleeve kit on the way for it as well as A Pull starter and a few other goodies. Should be a good runner once again!
Hey Bug great videos and content love your humor. I had a couple of question on a traxxxas 3.3 bearings? What brand and type would you recommend i use so many to pick from but i don't want to go cheap and have a bearing failure? I would like to change out my conrod and pin can you also recommend one other then a traxxas conrod or is that my only choice? Thanks....
No other rods available for Traxxas engines unfortunately. Just change it out after the first half to full gallon along with the bearings and wrist pin. As far as bearings i run SKF or NTN Bearings or usually in everything without issue. Avoid Traxxas bearings or Chinese bearings or fast Eddie engine bearings are soft stainless steel garbage and don't last. Acer bearings are good or NTN OR SKF. Os lc3 or LC4 Glow plug
@@thebug4046 Thanks bug ill look into the bearings listed. I also will be changing the crank to the RCR crank when i change out the bearings and conrod. I am running a LC3 plug also along with the OS11 carb.
It has a very small amount of it yes. But but DO NOT use sodium hydroxide it will destroy your engine parts in seconds and leave you will a pile of junk. Use a strong alcohol or cook the parts in green coolent outside away from people or animals. Or use brake parts cleaner
The only thing I can think of that would be different would be the amount of porting it has you'd have to analyze both photos to make sure they're the same or different.
Thank you! I wish I could give this a double thumbs up - much appreciated.✌ I thought my Savage was a 4.6 as I ordered that rear bearing for mine, and it didn't match the original size (13x24x6) and not a 14x25x6. Also my piston had a full skirt (no cut-out) is that weird or what? I just did a bit of research after watching your video and by the looks of it (based on the bearing size of 13x24x6) it looks like the Savage I purchased is a 4.1 (not a 4.6). Pretty hard to tell the difference between a 4.1 and 4.6 (without opening it up) - shame me once...
They may have had different versions. Always good practice to take out the existing bearing, measure and order from there. That way there isn't any chance to get the wrong size. Some manufactures even used the same block for different engine types (so they look the same/similar) but, all of the internals are different (crank especially). Did you ended up getting the correct size bearing for your rebuild?
@@a2rc Yes, I ordered it this week and should have it by tomorrow - made for the .21 to the .25 (apparently they are the same rear bearing). This is also my first engine with no cut-out of piston skirt too...
@@th3duke1 That's apart of why I enjoy rebuilding engines so much. They are like easter eggs lol they all have different surprises inside. I am glad you have the bearing ordered! You will have her running again in no time
Hey, TheBug404! I have a Traxxas Jato and, when I rev the engine in the air, no issue, the tires blow and the 2º gear engages smothly. Same when I put the car on the ground, the car moves with no problem. But, the thing is when I accelerate to the maximium on the ground, the car struggles to engage the 2º gear, while the enigne seems to wind freely in high revs, like without any friccion. I own this Jato for 2 years and never had this problem. The cluchshoes and the springs are fine. I teared down the shiftbox and everything is fine. I replaced the bearings, they're new, and thigten the screws, flywheel, etc... Can u guess what is going on?
That's hard to say without seeing it or hearing it it could be too rich it could be too lean it could have a fuel or exhaust system leak it could have a plug that's on the way out. Put a fresh OS lc3 glow plug in and open the high speed needle. If it gets worse then lean the high speed needle till best performance is achieved. If it has the plastic exhaust sometimes they melt and clog the pipe. Make sure the fuel tank is not leaking. Or the exhaust is not leaking. Very important!!!
Hey man not too bad and the dynamite 28 is made by SH different company but they are both very good engines and nice and interchangeable between their other brands. I hope your back is getting better soon!?
@@ofnaguycarlwatts8602 Sounds good buddy and yeah it's getting there slowly but surely still got a long road ahead of me driving me nuts I can tell you that much!
Hi bug what's a good piston and sleeve for a picco p3 .28 and do you know of a good replacement pinch bolt for the losi 454 carb? That pinch bolt bolt is hard to find.
The picco p3 is discontinued a long time ago. You will have to send the engine to RB Mods to have it pinched and get fresh bearings. As for a losi 454 it's literally just a rebrand SH 28 P8. Any SH big block or Dynamite big red pinch bolt carb starter crankshaft bearings etc will fit that engine.
It even has the fang off the ports that fource does I don't recall seeing fangs in other dynamite engines I'm thinking the engine was made by fource for dynamite
Hey to all if anyone can help me new to nitro rc an I have a o.s. 18cvr on a traxxas tmaxx takes time to start then when it does fire off runs for like 5 to 10 seconds then shuts down is it blown up or is it a easy fix?
If it was blown up it wouldn't run at all. It's kind of hard to diagnose that over a text like this I would suggest putting a new plug in as well as using fresh fuel and making sure you have no fuel or exhaust system leaks. GLOW PLUG OS #7 fuel 20 or 30% nitro no more than 12% oil. Also be sure to check out the Nitro RC enthusiasts group on Facebook Be sure to answer the 3 questions and posts a video of the issue. I'm an admin guy in dark sunglasses 😎 see you there! 🍻

Any time
Super clean is sodium hydroxide? I ask because this product is not available here

@@thebug4046 yeah, not going to put it haha, pure sodium hydroxide is going to corrode aluminum in a fraction of seconds lol.
I need a crankshaft for this same engine. What is a good cheap crankshaft that will work?
Dynamite 28RTR is the same for parts. Same with the force 28R
Awesome vids mate! Do you know the difference between force cp2804/5a piston/sleeve set and cp2804/5b??
