timberjack brake
« on: July 07, 2012, 05:03:24 PM »
I am working on my timberjack 200  and the brake needs work.  its a drum brake mounted on the transfercase.  It needs all new springs, shoes and wheel cylinder.  I was just curious to know if anyone knows if these parts cross to any automotive stuff. Also, has anyone on here ever converted the drum to a disc.  Thanks, Eric

i have been thinking about a disc conversion for a while. i think it would be the cats meow
with a little bit of machining and welding there should be a solution to the poor drum brake setup

I worked on a 230 TJ a while back that a guy put a rotor and caliper off of a Ford escort. Looked professional and didnt require much modifying to make it work. He said the rotor bolted up but he had to machine the center of it out a little.

I'm currently converting my 201B to a disc brake system.I am using a rotor and caliper off of a dodge dakota 4x4.I was taking pics as I go so I can put it on here when I'm finished but I had to stop my progress because I had to rebuild a 353 and just as that one went out the door another buddie lost his skidder engine so now it's another 353 to do.Is your transfer case a Rockwell or a New Process?

Thanks for the replies.  Bushmechanic some photos would be great.  As fas as what tranfercase I have maybe you can help me out with that.  There are some numbers cast into the pto housing but i cant get my head in there to read them.  The only thing i can read is a tag that say timberjack rebuilt part   Any help would be great.  Im new to skidders.

Hey EricR that is a New Process transfer case,they were popular in all the 200 series skidders right up to when the Eaton gear started showing up in the 80's.Those brakes are notorious for trouble and it seems that the disc conversions seem to work better.As for crossing up the parts to automotive I can't help you there I always got new parts from Timberparts in New Brunswick,they always had what I wanted in stock,sometimes it was a bit pricey but you can't make money with a parked machine!Now my old skidder is only used for snow clearing so I can wait to "get er done". :D

Hey EricR, Im not sure where your located but I'm in Western Pa. I am fortunate to have a skidder repair shop 50 miles from my home. I purchased a master cylinder and all the brake hardware in the drum for a total cost of $393.
I didn't think it was to bad of a cost considering the great feature it gives a skidder. Oh, and I had a new brake hose made that goes from the brake lock lever to the drum for $29. If you don't need the master cylinder than minus $137. I checked my local NAPA store and they had nothing of the sort. If you go through a John Deere dealer you will pay way more.

If you happen to run in to a junk S8 IH  get the rotor, caliper, master cylinder and the caliper mount off it.

The S8 IH had a disk brake off the tran and one on the rear drive shaft in front of rear hosing, both had the same parts, double disk brake system.

My dad put one on his C5, off the transfer case, you can weld or bolt the caliper mount on.

I removed the drum brakes from my TJ 201 many years ago.
 Recently I adapted and mounted a Honda rotor and caliber on the rear drive shaft and it brakes really well. The atco lever is my parking brake.

This looks  like the same setup as on a 240D I had. I think it was a 58 ford 3/4 ton wheel cylinder, but you still have to use your old cups. Had the brakes re-lined at local brake shop. That plate should unbolt so you can put it all back together at the work bench instead of standing on your head to do it.

Oh, an be sure to have the lower adjuster adjusted up prior to install, that way you can adjust the top one after everything is back together (easy one to reach).

As small as those brake shoes are, no wonder many people say they don't last long. They seemed to last ok for me, but I don't use the foot brake very often on a skidder.

Hi,  I have a 1978 timberjack 230D, missing all of the internals to the old disk drum brakes.  (I am getting a price of like $500. for all the internals including the caliper).    I would LOVE to see photo's of your conversion to a disk braking systems and what I have to do to make it happen.   I really would like to convert it to a disk braking system.   Any help is really appreciated.   I am especially curious how you were able to mount the disk caliper to the trans.  Thank you in advance!!!  Scott

Did anyone ever do the disc conversion then add a micro lock valve to the line to act as the park brake?  Would that work? The micro locks look interesting but I have not used one on anything yet.

Never trust a mico lock. Well never trust any parking brake but especially the mico lock they have been known to leak off.

My Pettibone has a disc brake, and a MICO lock on it. However, the MICO has never worked, so I can't say how effective it is. The machine came O.E. with a disc and lever parking brake, butit was disconnected by a previous owner.

OK, thanks for the info, lads.  When the disc conversion is done, what is used for the parking brake?

Build a pinion brake conversion using rear caliper off a cadillac eldorado or ford explorer with 8.8 rear.  They both had hydraulic disc brake with a cable actuated cam clamp.  Just set up your manual parking lever.  If you ever rip a line youll still have mechanical emergency stopping.  I recommend one on each pinion and a habd brake off a cab abd chassis truck is probably the longest cables you'll find.  You can always make them up by soldering metal slugs or trimmed off bolts to aircraft cable.  Steel brakeline works fine for a housing but i cut a few saw slits in it at the low points for water drain and fill em full of gear oil.  Oversize for a loose cable fit inside or theyll jam up.

  For sleeve adjusters i weld a nut to a plate and bore a thru hole in a short bolt, then a blind hole register in the head for the brakeline to seat in.  The bolt threads in and out of the plate to fine adjust the housing length.  Welding a baby vice grip to the other end that needs to be actuated has worked fine for me on redneck solutions.  Stick cable tail into vice grip jaw and chomp down. 

Rock auto is about the cheapest youll find either caliper.  Theyre spendy
