| Hello all, has anyone used the steer clutch springs from general gear? I got my order of disks and springs Friday the replacements look like die springs the pressure checks @ 220lbs aprox on the springs but the 62 year oem rusty ones checked 250 to 285 @3 11/6 inch, oem spec shows 235 to 265 thats only 66% im concerned any input would be appreciated. the unit is a 62 or 63 hd11e. |

In general General Gear gets good reviews. But If you have specs for springs and a way to test them it make sense to check. No matter how hard one tries most stuff comes from China. I had a new to me 1950's Cat D6. Steering fine until it was not. Pull one steering clutch and you stopped. I want to say springs were less than 1/2 of spec. But my tester was not the greatest. Set a bathroom scale in my hydraulic press, pressed spring to what ever the length for spec was. Read what the bathroom scale read.

| That is certainly a substantial difference. I bought new ones at Fresno Tractor years back, might be worth a try. |

yes i did test them used a short stroke hydraulic cyl 2 inch bore filled with oil and a pressure gauge installed in the port and the quil on my cnc mill to push the spring down on the rod to checking height 3 11/16 inch then used a hydraulic force calculator from baum hydraulic to psi to calculate 335 and 365 psi 365 =115 at gauge reading i think 106 was 335# i checked 4 new springs 2 were 60#,1 was 65 and 1 was 72#.Next i stood on the end of the cyl and balanced on it it come out to me weighing 220 lbs, the bathroom scales showed 223 lbs so i feel its a solid test. i have some pics in my phone of fixture and readings i will try and post. I called general gear they seemed like good people i'm probably going to send them back , i do feel the were probably imported parts. The thing that sucks i work as a maint mech in a 2,000,000 square foot caterpillar facility in morton il and its not a d6 .

All I can say is your numbers check out correctly on my calculator; it certainly appears that you have weak springs  |

| Like Les said your numbers are correct, 2 inch bore is 3.14159 sq in, so simply multiply your pressure reading by 3.14159. Those springs don't look like the ones I have, mine are round stock like the old ones you show. When I rebuilt my clutches the springs in one side were broke to hell. it looked as though somebody stacked round stock lock washers where springs used to be, they were all broke into 1 coil turn each. I still don't understand that. |

ok im going to take a stab in the dark here; mainly as HD11 books aren,t where i am. BUT is your HD11E a wet backend one ?? Wet backend clutch springs are alot stronger than the standard dry backend steering clutch springs; which is probably what general gear supplied you with. . ? Part numbers from the right books will tell the storys ! ------------- tits tyres and tracks they all cost you money |

| no the replacements were a die spring type we use a few around the plant on vertical conveyors. ok here's the deal on the dozer i bought it broken a couple months ago with a broken bevel gear shaft. Someone local was parting out a hd11e serial number 12000 and change my hd11e is 7464 dry clutches and hydraulicly boosted steering and wet clutch trans. Misreading the manuals i went down and removed all the clutches, brake drums, bands, and bevel gear and shaft and blade cylinders there are a lot of differences in the machines steer clutches the way they are acuated the bevel gear is the same the shaft is .340 wider from brgs out and brake drums are .340 narrower.my pinion and bevel gear were worn a little mostly the bevel gear i used the bevel gear and shaft set the bearing preload per the manual and the backlash by moving the side shims came out at.007 backlash spec is .008to.014. then i decided to make up for the extra shaft length be making new yoke buttons from drill rod and heat treated then hardened to about 60 rockwell c scale a file is 65. Everything looks good so i ordered clutches, brake linings, and springs. Between me and my son we want to build ponds it prabably wont need to run 100 to 150 hours i only have 5000 in it and parts. So if it breaks i can at least scrap it, and yes the wet springs are longer and pressure is like 750 lbs i think it has to be higher because 50% less surface area from grooves in the frictions and oil. |

| I decided to try and cutdown the wet springs heat and fold the tails regrind the bases the picked 8 wet springs and 8 dry springs alternated them 4 in a cross on each hub my total calculated pressure from all 8 springs are in the 3750lb range at 3 11/16 but the wet springs build pressure quicker when compressed farther so i hope it works i will let you know how it turns out figured i had the parts and they were not really good so i might as well try. |
