Slipper for my xls
 

Hi guys I need a layshaft and slipper for my xls runner...can anyone help me out?

I think from reading Luke's thread that the U1214 Bosscat unit is a good option and enables RW spurs to be used......all help much appreciated.

Dan

What are you going to be running through it pal lipos or nicads as if your useing lipos you will need the bosscat one which are like rocking horse do do but if your not running that power through it you could use the wasp or Procat slipper.

I have drawn up a conversion shaft for my bosscat to run a modern slipper (b4 style) but I don't know how popular this would be. Seems like a few out there want to run their old cars with modern power

Tell me more I would be very interested in 1 or maybe 2 if you could get one to fit the mms layshaft

I luckily picked up a BossCat slipper assembly from Paul (CAT3K)... but i've realised since just how few & far between they seem to be :bored: - i'm also surprised just how popular the Bosscat 'Sport' must have been!

I'd be interested in a layshaft being machined that allows the use of a double disc slipper assembly - as this has got to be better than the single disc BossCat Item... would be nice if it used parts from a later Schumacher e.g K1 or Cougar SV or KF (to keep it all the same brand)

As Dan says, any chance of a SV based slipper conversion?

Would be interested in a lay shaft if it stayed with schuey parts..

That's the type of input I was hoping for, thanks guys. I wasn't sure if a b4 type dual slipper would be preferred for simplicity and ease of parts, or if I should keep it Shuey. I'll do some checking with my machinist and see if he is willing to experiment. I just ordered a sv2 slipper set from a US seller so I should have it soon to experiment with

You could even go for a sx3 slipper assembly if you wanted to keep it shumacher thay are easy to get hold of

I tried to look up the sx3 exploded view and manual- both are offline at schumacher...but from looking at the pieces they are very similar to the cougar as far as the square drive and such. I will need to get the sx3 hubs in my hand before I can say for sure but they look very compatible with my idea for the shaft.

Just seen all your replys guys!

I'd also be interested in the layshaft to use a modern slipper!

I'm not familiar with either the Cougar SV or CAT SX3 slipper assemblies.... but either way it would be best if any manufactured layshaft used parts that could still be purchased from Schumacher (so presumably from a car in the current line-up)

I "think" the slipper plates are the same or very similar between the SV and SX3/KF.

In all honesty though, the bosscat slipper can amost certainly cope with as much power as the rest of the xls transmission can take!! The frustrating thing for me is that I've probably thrown away enough bosscat (same as CAT 2000/3000/fireblade) slipper plates / pads over the years to keep this forum's users going!!

Well, that was the reason I was thinking B4 style, as that opens it up to losi (even hydradrive), associated and others. That top shaft is also much easier to fabricate. I will probably start with a B4 style and then progress to the Schuey. A bearing adapter will have to be made as well, as the bosscat slipper is the bearing adapter.

As far as the compatibility- will the Bosscat share compatibility with others assuming the drive pin holes are in the stock location? For example, would a original Cougar, Topcat etc use the same shaft? I haven't done my research.

The 2wd cars would (I assume) be different since they only have a single belt/drive pulley as opposed to the double pulley with (space between for the main long belt) on Bosscat/ProCat.

I'm not sure which of the original CATs (SWB, XL or XLS) had the original 'integrator' system - but anyone wanting to run any sort of slipper on their CAT would have to upgrade to a drum diff & fixed layshaft pulleys.

All above had the inegrator .

I've made a slipper for my ProCat that uses the layshaft from an original Schumacher procat option slipper set but with a modern Schuey spur and slipper pads. This involved turning some custom ali slipper plates, making a T profile lock nut (as the slipper shaft was a little short). Spring is from a Team C slipper.

I run it with a MMS one piece drum diff. All of this would be completely compatible with the earlier CATs and probably BossCats too.
It works perfectly with lipos and 8.5 motor on high grip astro and so far no transmission problems.

My design was based on reusing existing parts wherever possible with minimal new manufacture but really a new layshaft that was long enough to accept a standard nylock nut would have helped.

3 words Nigel...

Make me one!

I wish I could Dan, but I no longer have easy access to a lathe.
:-(

I also ran a bosscat slipper in my procat with an 8.5T brushless and lipo indoors on carpet and found the weak point to be the tooth pitch of the belts and diffs. I did get a price to have some new MMS style diffs machined but lost my way with it some what and it is now on the back burner. Thread here if anyone is interested:

The SV2 slipper showed up today and I have taken the measurements- I think I have a game plan to make it fit. It will require a special bearing adapter for the slipper side, because the old slipper inner hub was the adapter and of course a special layshaft

I'll be really interested to see what you come up with gomachv.
There certainly seems to be demand for a good slipper solution.
Keep us posted.

Here's some pics of mine, think I've got a sketch somewhere too, I'll post it if I can find it, in case that's of any use to you.

Found my fag packet sketch! ...

I suddenly remembered sending it to Derbydan, how's your ProCAT coming along Dan?
Do I need to get ready to race? ;)

Ndpd I like your solution well made I can't wait to see the outcome of gomachv's if only I had a lathe :thumbdown:

this is the drawing i will present to the machinist. The bearing adapter is split, otherwise you couldnt load the pulley half onto the slipper side.

I want it.

NOW :)

Looks like a great start.
But, where is the spring going to sit?
Unless I'm missing something, I can't see how you would adjust slipper tension?

The drawing does not show the long threaded setscrew that will hold the locknut, exactly like the old losi design. The hole you see will be threaded. The SV2 adjusted on the other side, strange setup

Cash waiting.... :)

Just so ya know im serious....just grabbed this today. It's a toy, but should be fine for taking the shafts from 3/16 to 4mm....and after I build the fixture I should be able to cross drill the pin holes too

That's mint I would love the space to have one of them O the bits I could make myself. When there done pal I'll have at least one of you

Errm, not just yet Nigel! I'm hoping to get a few bits back from Fibrelyte soon... then its on with the build :thumbsup:

Oooooo what have you been spending on then I've got to wait a few days till I can put a order in :thumbdown:

Guys if its just the shaft you need making I might be able to get a few made, but I woul need a shaft to copy, please let me know as I need one too :)

Thanks for the offer Jiffy!
Lets have a chat one tuesday night at Silverstone (I'm not there this week).
