rebuilding and engine ever worth it?

[NooP]

It seems like if you were to rebuild an engine properly.(meaning piston and sleeve, connecting rod, bearings, screws, and seals.) For most companies it seems like youll be pretty damn close to the cost of the complete new engine. If there is anything about this hobby I dont like, its that the rebuild cost of the engines seem to be rediculous.

For wat it's worth, I've always figured it's just plain easier to buy a new engine instead fo rebuilding. I mean the price of most of the rebuild parts you and generally buy another engine.

Have to aggree with EP. I do like the pinches I've seen from OSRocket and would go that route b4 droping money on a new mill. From what I've see his work restores an engine back to tighter than factory and requires a breakin and last for as long as the original. After a few pinches then pick up the latest new powerplant.

I forgot to say, when my $400 engines break and if the rebuild cost is anywhere near the cost of a new engine I will willingly buy a new engine vs trying to rebuild the existing engines.

You don't always have to replace all of the parts like the bearings and things, you could just replace the piston and sleeve for about 50 bucks and you have a whole new engine without spending all that money.

 

[El Pirata]

Yeah but since you've got the engine torn down to that point it's better to be safe than sorry and replace everything. I mean would you not be ticked off to no end if you just rebuilt your engine and right after you finish breaking it in you burn up some bearings you opted not to replace during the rebuild?

 

[AC48]

I'm just saying that if you didn't have the money to buy an engine you could just replace the piston and sleeve. Sometimes it isn't worth it to replace the whole engine.

Show me a decent engine that has the a piston and sleeve for 50. Off the top of my head, I think some of the wasp piston and sleeve go for right around 50. But every other brand and some of wasps engines rebuild prices are rediculous.

My point of this post was not to ask if it was worth rebuilding or not. I already know that rebuilding an rc engine is hardly ever worth it. My complaint is that it should be worth it. We should be able to rebuild our engines for a decent price, but because these engines are so simple and have very few components, rebuilding means replacing more than half the engine which consist of bearings, gaskets, screws, crank shaft, connecting rod, and piston and sleeve. Because that is pretty much the whole engine minus head and block, the price is extremely high and unreasonable to rebuild.

It would be nice to rebuild our engines for reasonable prices, but it just not seem like something that can ever happen because of money.

just my Thank you and have a nice day.

Thanks. You just made me think of looking into the price of rebuilding my monsters. I mean since it's a $400 engine, I wonder if the rebuild parts are priced accordingly higher so that people will opt to buy a new engine rather than rebuilding. Hmmmm...

when I looked on tower, they dont even offer the parts to rebuild it.

When my Traxxas Pro.15 wore out, I priced a piston/sleeve and crank bearings for it, and found that for about $10 more, I could buy a complete new engine...I guess if you had some $400 Novarossi, then rebuilding would be worth it. But for the average basher, go get a new engine.

Here is the piston and sleeve for a 140.00 dollar engine, the 12 R SS:

You can't tell me that the 12 R SS isn't a decent engine because I have one and it is great. You can rebuild this engine for like 34 dollars. To me, that sounds like it is worth insted of buying another 140 dollar engine.

 

[El Pirata]

There's more to rebuilding an engine than just replacing the pistin and sleeve. There's the crank shaft, rod, bearings, gaskets, etc... These items add up fast when rebuilding an engine. So let's say you blow $100 total for everything to rebuild the engine. For $40 more you get a brand new never used fully warrantied engine.

 

[AC48]

You don't have to replace those.

You're right, if you wanted to replace all those things it would be better to get a whole new engine, but you can just replace the piston and sleeve when you loose compression. By doing this you will regain compression and hp without buying a new engine but then you would have old other parts like the con rod, crank shaft, ect... That's all I'm saying.

If your talking about the Wasp .18 Id just spend the extra $30 and get a new one. Either way your gonna have to rebrake it in, but with a new one at least you wont have the extra time of rebuilding it.

You can use HPI's engine exchange for the 12r SS it will only cost you 99.00$ . You just have to send them you'r old 12r SS, i think it is a better deal then rebuilding.

We'll take my engine for example, retail is like $390 +/-. The price of a new piston and new sleeve is $176 direct from Trinity. The crank is another $175. Heck, that's almost the price of the engine itself.

 

[alkyula]

there is a hole crapload of feedback (i think like 300+?) on guys that are 100% satified with the results of the osrocket pinch on ebay...in all youll be spending about 18$ to ship it and have it pinched. some people even said the pinch was better than factory..and power was great after osrocket. now this does not include any wear you may have in the rod, wrist pin, crank, or bearings..but i feel as though even if you blew a con rod or a bearing after doing an 18$ pinch...big deal..afterwards you can pick up a bigger better brand new mill, if not..then you got a hella of a deal on a basically brand new (compression/power wise) engine.

 

[AC48]

I guess for some engines, like cheaper ones, it is better to rebuild, and other more expensive ones it is better to buy a new one.

What engine do you have that costs 390?

You have to keep in mind that by the time you loose compression, most of the other parts are already worn.

Thats a damn good deal in my book. Whats a good .12 roar legal hpi engine? I think I'm going to take that route.
