no speed

[biggus]

I have a 16hp tecumsch engine on a 70s scrambler,and its real slow.I'm sure my riding mower will out run it and its over 12 years old with the same hp.The engine seems to run ok,has good pulling power,and rev's up fine with belt off .With engine off I checked to see if acc. was opening all the way when I pressed gas pedal and it was.The choke is open to.The engine don't rev up when pulling so I'm sure nothing is slipping.It just don't wind on up when moving.My acc. linkage is hooked to a lever on bottom of engine block,from that lever a spring and rod hook to carb. I don't know if that lever on bottom of engine is acting like some kind of governer. Any help would be appreciated

if your throttle linkage is all good, i would think your problem would be in your clutches not engaging correctly. probably rusted on the shafts or something

ok,it is a governor holding back the engine from running. I unhooked it and engine seems to run fine .Now I just need to modify linkage to hook up acc. Meanwhile since it's been sitting, now I have lost all steering.See some fluid under 1 rear slave cyl. and possibly some at frt. steering cyls. I had tried bleeding system before but I beleive all the hydraulic cyls. need rebuilding or replacing. Anyone know where I can get some good cyls. are overhaul kits?

Note I have saved but never dealt with, just what I was told but.......

mrscrambler@ juno.com = seal kit

I believe it is complete seal kit for the slave and master cylinders. Let me know if you find out.

Gee Larry, where did u hear that?

the origional belt replacement for a scrambler is a napa 6013, i think, you might want to put a new one on...... and a spare too, saves alot of time later.....

replacements are.....sks 6206 2rsgem and 6206 2rsc3 kuyo's

seal kit

I never did get a response from mrscrambler@juno.com about a seal kit for the slave cyls and steering master cyls. Also I would like to know is there a transmission anyone could recommend that could be adapted to my old scrambler which does not have one?Sure would like to have a reverse. If there is, where do I get one and any idea what one should cost?

scrambler

still haven' got the steering fixed so maybe I don't need reverse

scrambler

i had a scrambler at one time and reverse was a big deal to me so i found out comet made a F-N-R transmission that i was going to adapt into my scrambler but instead i made a deal on a maxII and got rid of the scrambler you can still find those transmissions on ebay they are about $300 tho

[LarryW]

I would look into adapting a fnr trans from a polaris quad. You know it will handle the power and I was watching them for a while and you could get them pretty cheap on ebay.

trans

I haven't been able to locate any fnr trans. on ebay are anywhere else.

Here is an example of what Im talking about. This has H,L,N,R. It is also for a 4x4 so there is an extra output for running a jetpump, prop.... You dont really need the 4x4, it was just cheapest one I found. Dont buy a "buy it now" , just be patient and you could get them for like $50 plus shipping. Not a expert but polaris trail blazer are fnr and trail boss are HLNR and both are 2wd to help you search.

I can help out with the seals. There are 3 different seal sizes for the trans. The brake block cylinders are one size and the steering slave and master were the same on the early machines. I think the steering slave were changed when they went to the square block. Do you have the square steering slave block or round?
I also purchased a Polaris trans for a similar retrofit. All the ATV fnr trans have a built in reduction and will effect the overall performance of the vehicle. I don't think the scrambler dry clutch will handle the extra torque from the Polaris trans. The Scramblers dry clutch is on the high speed side of the overall gear reduction and the surface area and spring pressure are calculated for that. I have installed a t-20 in my race scrambler that works well but its a lot of effort to install.

seals

I have the square steering slave blocks.Also would like to know what kinds of brake pads for steering would work and where to find them.I have heard the pads are glued on,if true what is best glue for them so no chance of them coming off?
