Savage's Main Spur Gear is breaking very Quickly....Do U Know Why...?[:@]

alvinl

It's your mesh. My 1st spur stripped very easily. My 2nd one is on about 1 1/2 gallons and no signs of wear. The mesh from the factory was too loose. It was adjusted as loose as possible. I did not discover this until I put it back together after stripping my first spur gear. Check your mesh, do not just put it back to the factory settings. The more I deal with these trucks the more I am starting to see that people are right when they tell you to always tear your new RTR truck down and check everything.

Thank U alvinl,

i try every setting positions of slipper cluch.But its quckly burn or broke.

Does it identical Savage Problem,or HPI's Gap?

alvinl

Here's what I did. Tighten the slipper down all the way, then back it off 1/4 a turn. Now adjust the mesh between the spur and the clutch bell. Put a doubled piece of paper between the spur and clutch bell. Tighten the mesh by moving the motor towards the spur. Snug it up but not overly tight. Tighten all the screws down, and make sure the motor is not adjusted crooked or it will just strip the spur again. Now remove the paper. It should be crinkled but not ripped. Now turn the spur gear all the way around a couple times. It should turn freely with no binding. If all is good, take one motor screw out at a time and apply blue loctite to it. Put the screw back in and do the other 3 one at a time. Let it dry and take her out for a test run.

I am not an expert at this, but others here helped me when I was in your spot. The guys here are very helpful and I read several posts before I had a clue how to adjust the mesh. Just make sure sure you do not get the motor crooked when adjusting and the spur moves freely with no binding. Let us know how it turns out.

i replaced the steel spur insted of nylon one.i mean HPI could have steel spur in standart Kit.So there is no nylon problem.

As i understood Savage is a Entry Level RC Truck.

Maybe they replaced many Spurs or other gears to prepare advertorial Download Movie.

i thank u for your assistance alvinl.

I HIGHLY reccomend going back to the plastic spur gear.
If you're new to rc's and MT's you have to learn how to do certain maintaince issues. If you do not know how to adjust the spur properly and go to a metal gear you will ruin your clutch bell.
Once you learn to get the mesh right a plastic gear will last a long time. My current one has been on for nearly a gallon.
Also, it kind of sounds like you are confusing slipper clutch adjustment and gear mesh. They are two seperate and distinct adjustments and both need to be done properly if you don't want to keep destroying spur gears.
Reread Alvinl's last post, he explained how to do it very well.

Most RTR's are considered "entry level" only because they do not require assembly. All hobby quality rc's have a learning curve. Contrary to what RTR implys, very few rc vehicles are REALLY ready to run straight from the box. This is a hobby and these trucks are far more complicated and sophisticated than department store toys.
And, for the record, the Savage is one of the more dificult MT's to work on

Nylon Spur Gear Changing Process, Can NOT be a Hobby.(hpi Savage RTR)

This must be such as MONEY TRAP...!

Gears close : O.K

Multiple Slipper Cluch Adjustment : O.K
.................................................. ...........
RESULT: BROKEN or BURNED Spur Gear.
***its Totally MONEY TRAP***

u could NOT Know Everything , But u must learn that Steel Gear is Fundamental Solve.

CatchMeIfYouCan

hmmm... $3 spur or replace $70 trany or what ever else. Youll learn

wrchobby

i catch u somehow, couse your spur going 2 meltdown anyway.....clever one...

DaveG55

You're quite correct, I do not know everything. I never claimed to. I do know that I've been playing with and working on rc vehicles for nearly 40 years. How long have you? I also know that in cases where newbies complain and don't listen to experenced help that they end up spending LOTS of money. I also know that you WILL destroy something more expensive with that steel spur gear AND that you will blame it on the truck. And, finally, I KNOW that you will NEVER be happy with that truck.
I wish you luck but I seriously doubt that it will help you very much.

I had problems with plastic spur gears. I went steel and have run almost TWELVE gallons with it with no tranny problems, no clutchbell problems or no drivetrain problems for that matter. If the slipper is set to tight you will break something. If set correctly, it will do it's job, and not destroy your drivetrain.

tmodlin

Look man. You started out asking one of the most frequently asked questions on the board. I would have never guessed that you have any experience at all with RCs just going off your first post. I, like Dave55, highly recommend setting the spur gear mesh properly and the slipper properly before you go and spend money where it is not needed. Sure, you might put the new steel spur on and never have a problem but the chances of that are unlikely if you cant even set the mesh properly to begin with.

So no, your credentials dont mean jack to me. If you have been RCing for 22 plus years you have missed out on a lot of much needed information.

DaveG55

Golllyyyy geeee,
All that experence and defeated by a plastic gear.
Seems like you would have figured that out long ago, especially since you say you're an HPI dealer.
As I said, good luck to you.
Now feel free to have that last word.

I rather not take the risk of destroying a 70 dollar tranny thank you very much. You can replace the spur gear over 20 times, and it will not cost you as much as the tranny costs

wrchobby

Dave Said that,
"All that experence and defeated by a plastic gear."
i said,
There is NO need to experience 4 Fourty Years, to solve this Problem(am i right)
i try to tell you ,This is a Factory Gap.
Finally i couldnt to tell you.

Look what Bagged97 said that,

"I had problems with plastic spur gears. I went steel and have run almost TWELVE gallons with it with no tranny problems, no clutchbell problems or no drivetrain problems for that matter. If the slipper is set to tight you will break something. If set correctly, it will do it's job, and not destroy your drivetrain. "



tmodlin Said that,

"Look man,I, like Dave55"
"So no, your credentials dont mean jack to me"

i don't care who likes whos....we didn't discuss that;
Who u are.....?
if my credentials didnt mean jack to you,why did you reply and barge into the thread.

Look guys what i m gonna say,

There is 3 ways 2 Learn

1-) to try to find out the Right Thing------- Almost Impossible.

2-)to mimic------------------------------------The Easiest Way to Learn

3-)to had been tring--------------------------The most SUFFER way to Learn.

And how do we know what he did to his car to make it hold up.

Do urself a favor, and stick with plastic

Philster

Experience tells us: A steel spur can work, and so can a plastic one. The steel one costs $70.

A poorly adjusted mesh with a plastic spur will cost you a plastic spur ($3). Properly set, however, it will last and last and last.

A steel spur does indeed place other drivetrain parts at risk, if the slipper doesn't work. In cases where the spur would break first, likely a tranny part will give way first.

Alot of people run steel and get away with it. But for 70 bucks, and for the risk you incur, should you really skip out on plastic, when we all know that when set properly, it will not strip???

Make sure that the engine mount screw are tight.

bagged97

When set correctly, plastic will last. However, over time it will wear out (dirt, pebbles, slipper friction ect). Steel will not wear out, so when set correctly, it should last forever. Besides, a steel gear is not $70. I've seen them on e-bay for as little as $20. I'm not arguing, but if one can't keep something a simple as a slipper clutch set properly, how much other junk do they not know how to adjust which leads to a broken down truck?

CatchMeIfYouCan

It does all matter if its set properly, but the plastic spur gear is also a stress point. If you make a driver error like landing on the gas on a big air something is going to give! The ? is where do you want it to snap.....hmmm $3 or hmmm.

I know I run with about 6 other savys on the weekends and one of us does run a steel spur and has never had to replace it and is a smart ^&* about that. But he has also gone threw a 2 speed a 3 speed and a rear end, and wonders why none of us replaced any of that yet? hmmm.

I prefer plastic spur gears. If the mesh is set correctly, the teeth will not strip unless a rock or something gets jammed into the mesh. If the spur dies from anything other than stripped teeth, it is generally a symptom of a problem somewhere else in the truck. Melted spur centers are often a sign of a slipper that is slipping too much. Melted teeth are often a sign of slipping clutch shoes.

bagged97

The gear is not supposed to break, it's supposed to slip. The weak point link is the slipper action, not the slipper gear.

Geeza!

Hi, I also wouldn't us metal spur gears, even the new HPI ones, as already said, plastic spur gears will last a long time if they're set up properly.

My trucks get plenty of abuse, they all run plastic spur gears, without any issues, also i have peace of mind running plastic SG's.

I have my SG's fully tightened, meshed properly, job done!

wrchobby

So u do urself a favor too, & stop beating about the bush; tell me frankly,

Why do u defance to plastic against the HSS one.(76 RockWell Hardeness)
