I got the TigerDrive S689 and the RB Cover for it, installed it but it is not turning over the engine looks like the tigerdrive shaft is not wide enough to make proper contact with the one way bearing anyone else tried this ? am i doing something wrong here ?

I have the same problem. Rody is there a one way bearing from RB Products to fix this problem?

We did not encounter these problems..., have you the possibility to measure the diameter of the shaft which is going into the one-way bearing. Please use a digital calipers if you have one.

hmm, unfortunatly I do not have access to one, I dont know if JAD has one, however I have been in contact with the tigerdrive people and they say they only have 2 shafts 8mm and 6mm. I would expect that we must be using the 6mm shaft as the based on current tolerances 8mm would not fit at all. I have been looking at the possiblity that when the shaft is in place it is not long ebough to contact the one way bearing completly tho at a glance that seems fine. my other guess is that maybe the stock rb shaft is a bit larger than 6mm is that so Rody ?

The Shaft for the one-way bearing needs to be 6.00mm and from the sample we have tested the shaft was long enough, so we do not know what exactly is the problem here.

hmm, the odd thing is rody that if i put back the pull start there is no problems, hence why I figured that maybe their shaft was smaller or yours larger, maybe by 1/4 mm or there abouts. it could also be that since I've been using my engine with its pull start for a while that the one way has become 'fitted' to it and maybe I need to get a new one way bearing. But before I buy a new one way I'd like your feedback on whether this makes any sence at all

I do not think that the problem is the one-way bearing, I think more that the problem as you describe it is related to the diameter of the shaft supplied with the tigerdrive system.

I would tend to agree with that I suspect that the tolerances may be different to a +- 1/4 MM this would explain the differences but to determine which is which it would need to be checked with a very accurate caliper, and unfortunately I don't have one

I am having a hard time finding a shop that has got the tigerdrive backplate. The only place where i found it was rbproducts.com... where to buy one?

Rody, the shaft from the Tigerdrive is definately smaller than the stock unit I soaked the One way bearing in nitro cleaning fuel on satuarday got it to hook up with the tigerdrive long enough to start it ran it for a while shut it down then it would'nt catch again I pulled it out and had a look and I can see where the one way bearing seems to be making slight contact with the conrob (metal has been rubbed) in addition when I shift the rod arround in the one way I can feel a certain amount of play.

These stories kinda make me affraid to buy a tigerdrive system for my 728. I I only knew for sure it wouldn't fail. I just want an electric start possibility for my non startbox compatible savage

Thanks Rody, I have already ordered a new one way as soon as I get a hold of it I'll let you know, beyond that issue the tigerdrive solution work very well. Tobberloth do you have an extended chassis on your Savage ?

Nope Reecek I've still got the stock TVP's. I've been told that if I want the Tigerdrive to work (to be able to start it)I have to Dremel my TVP a bit to get some space for the starter shaft.
I think that's why you ask?

tobberloth - yeh, thats right you're gonna have to cut a hole in your tvp and dremel away some of the rear cross beam as well as a compromise I trimmed away some of the plastic top on the tigerdrive to get the space reqd. I havn't seen any problems this adjustement has created. i understand the extended TVP's don't have that problem, I'm thinking of getting some lowered extended TVPs myself

Do you have a picture for me reecek, so I can see what you mean and what you have done exactly? I am not thinking of getting a pair of extended TVP's right now. If I do, they're gonna be carbon ones.

SUTblue2 - The roto-start that is used with the TM728 is the Tigerdrive, coupled with a special backplate from RB. We were discussing some issues that we were having involving the one way bearing in this configuration. It is conceivable that you could take the rotostart and the roto-start (i'm assuming you mean the one that comes with the savage) and fabricate something the big problem there is the shaft, maybe you could get one made that could be used. I also don't know if the roto-start is strong enough for use on the RB.

why i ask.. the schumacher mention made me think of a issue most do not know..
high in castor oil content, or bluethunder (what every they use for a oil) makes a internal 1 way bearign slip ALOT, ive had to flood engines on that fuel to get fuel to wash the oil reidue out of the bearing.. it slips so bad you would think the pull start is not even hooked up to the engine..
one of you with it does not work at all do me a favor.. pull the glow plug out, remove it completly, lay a rag over it, flood it real good then clear it out and try again to see fi it works.. i ONLY suggest someone who knows what they are doing to try this.. this is one of the reasons i use odonnal fuels.. traxxas/bluethunder/hpi/monster all make them slip.. i cannot get rb fuel so no idea on that..
posted
tobberloth - sent those pics to you, sorry for the delay coudn find my digital camera.
crsmp5 - I'll give that a try later in the week but I'm still more concerned that the one way as it is now works fine with the pull start shaft and not with the tigerdrive shaft, if I do a good cleaning of the bearing I can get it to hold, for a while then it slips again - hence why i suspect that the tigerdrive shaft is smaller that then RB

well give my idea a shot.. ive seen this issue way to much on savages, the fuel sits int eh warm engine, evaporates, leving a oil residue.. let us know what ya find.. roto start on a savage really brings this issue to life also..
posted
Yep, CRS is right, to much oil content in your fuel will cause the internal one way bearing to slip, making you think that there is a problem with the bearing. I had this same problem when using Traxxas top fuel (16%) oil. Once I switched to O'Donnell race blend the one way bearing started working again, and has ever since the switch.

Reecek, thanks for the photo's. I understand what you meant now. Maybe extended TVP's are better but you will have to buy a longer dogbone too.
CRS, I have been experiencing the slipping of the bearing after degreasing it with motor spray for the first time. Prior to that next day I've never had slipping issues so I do not think the monster fuel contains a lot of castor.

Tobberloth These guys have one that uses the same dogbones - http://www.rockconcepts.net/ Thinking about trying one myself, I want a lowered TVP but I don't want to be too much longer and this seems to suit my requirements

Well that certainly looks nice (although I don't really get the tilted fueltank idea)but it's very pricey. And would you think that 1/8 inch extra length will be enough for the tiger drive to fit without drilling holes in the TVP's? 1/8 inch isn't a lot...

tobberloth- nope you're gonna have to drill the hole in the TVP, but you probably wont have to grind the rear cross member which is what bothered me the most, and yeah It is quite pricey! can get some others for half that but they all stretch the truck

Well another advantage with extended TVP's is that I can use the long RB header. It now touches the shock, but I do want to use that header.

Is it this one you mean CRS http://www.neweramodels.com/item.cgi?part_id=522? Have you tested this one yourself and what are your findings? I was keen on having everything from RB but if this fits on my stock chassis... And while I am typing anyway, do those Mugen composite clutch shoes fit on the Savage 25 RTR 3-shoe clutch unit without mods?

inside port, as you can see they used the side of the pipe to make the opening, why its oval
those are lowered .5" tvps i had designed, on stock tvps it clears the shock without issues.. the header/pipe i raised up to keep it from rubbing the tvp is the only reason the spring is close..

Looks good... Has it lowered your temps something or did it only supply extra low end torque?Did you experience a big noticeable change in performance? Thanks, and nice shocks btw

the 063 lowered the temps along with knowing that if the LSN is too rich it makes it run hot, it feels like it has a little more bottom end, but it just fits so much nicer its worth it.. not crappy cast potmetal like stock..
posted
It really resembles the #01316P now I compare them. I think I'll put this on my "next purchases" list..
BTW I did not know a too rich LSN can raise the engine temps too! I have to keep that in mind.
