H brake disc

I

Well-known Member
Does anyone have a source besides Case/IH for the fine spline brake discs for an early H?
 
Don't think that attachment for a H was common enough for the aftermarket to make a disc for that hub, not sure though maybe someone knows a source. You may find a place to reline or sell you the lining to repair yours if the plates are still good. If you don't mind me asking, what is the cost at the dealer?
 
Ian, are these brakes after market add on? My book show disc on 1953 H's after serial #391358 which would be a very late 1953. The only disc it shows is 5 5/8 x3 3/8 10 spline an those retail for $13.41 each and should cost about $11.00 plus ups. Good luck gene PS. I don't anything about a fine spline.
 
W.A.R.R, another company made some of the parts, but the kit or attachment was sold by IH for tractors below the serial # you mentioned. Bull pinion gears had to be changed on a early H that used a key in brake drum to the splined type for the special hub in disc brake kit to work on those models though.
 
Ian - If H has aftermarket (Lambert) disk brakes, any good clutch and brake shop should be able to reline the old disks.

Or it's one of the last production H's factory equipped with IHC disk brakes (10 spline hub) Super H disks fit and are readily available.
 
On the M, they had a double splined hub that fit over the stock bull pinion shaft then the disk brakes set over that shaft. I did find that an oliver Super 88 disk brake was the same spline as the M with lambert brakes. I dont know about the H, but the 88 disks were a direct swap for the lambert brakes I had to find disks for, and found em by accident! I can recut a new set of brake disks with the proper spline if I had the spline in question. Hope this helps, ChadS

[b:88a7a672ce]Chad,
I believe you are right about the Oliver brakes. I think the H brake discs are a different diameter than the M but use the same spline. If the Oliver 88 discs are the same spline but the the diameter is larger you can lathe them down. BTW the discs are still available from CIH as p/n 1975451C3.

The part number for the Oliver 77 and 88 brake discs is 106724A. 7 inch outside diameter, 4 inch inside diameter, 29 spline.
 

After doing a bit more research, I doubt if the Oliver parts will interchange. I found out the original Lambert discs are 5 5/8" O.D. 2 3/4" I.D. and 26 teeth as opposed to the Oliver 4"I.D. and 29 teeth.
 
Chads on the H disc brake attachment # 358255 R91 they used the same actuator as the late H and SH used on that disc brake set up, so I would guess the OD of brake disc would be around the same as SH, 300 ETC. Never thought to keep track of the ID and OD measurements in the past. H used the same type splined hub on bull pinion as the M you mentioned. IH started offering the disc brake attachment to replace M band type in 1952. Don't have any proof of when H was first offered, but probably around the same time. Some information shows some of the disc brakes parts from Lambert and some shows Auto specialties. I'm guessing some of the adapter parts was made by IH. Also still checking on the 3 heads we discused awhile back. Have 2 of the heads and waiting on the other to see. You were probably right on the SH head, the problem is to many places show valves of different lengths. Going to look at real thing and see whoes information is correct. Dave
 
Rusty does it show 6 X 3-1/8 for a M. I had that wrote down but didn't write enough info along with it to be sure on a answer.
 
Yes were refering to the attachment IH sold to convert band brakes to disc. They used the stock M or H bull pinion used with band brakes as long as it was the splined type and the stock band type brake pedal. Outside covers used 3 mounting bolts instead of 5.
 
I want to correct myself on the 88 brake,,, its not a 88, the one to use for the M lambert disk breakes is off a MM UB. bout a 1/8 bigger around, which does fit, and its the same spline as the M-Lambert hub. On the heads,,,, kerosine heads for the H, I was thinking took a different valve than a gas H head. Reson for that might be how deep the chamber is on a kerosine head, VS the gas head, they moved the valves up higher in the head away from the piston, and did not change the actual overall thickeness of the H head. Im certain on the 8043DD head only being on any SH no matter the production year. Ive got a eary 53, and had worked on a late stage 2 SH and both had 8043DD heads. I know the 8043DD Sh head was an indetical casting to the 300-350 gas heads in design as far as the casting, Im 95% positive they take the same valves. 8043DD ports are not the same as a H 8043 gas head. The H gas head can yeild more cyl pressure when machined for best performance, but the 300-350 head will out flow the H head by quite a bit when a little port work is done. Chad
 
Thank you for all the replys. I didn't get back to a computer till today (the 31st). They are the 26 spline conversion ones. Just ended up getting them from CIH dealer.
