Questions: I have attached the engine to the bell housing and through the access port it looks like there is 1.5 inches between the bearing that is pushed into the clutch fingers. The clutch pushes all the way to the floor and barely makes contact. Did I forget something or how do I adjust this without pulling engine again?
Question By: Roger on Sep 11 2020 2:37 AM
Probably a free pedal travel issue. I would adjust your release cable to the proper measurement.

Questions: will this fit my 1960 DJ-3B?
Question By: AJ DeWitt on Feb 3 2020 6:40 PM
Yes, as long as this is the same 8.5 inch clutch.
Answer By: Willys Jeep Parts Tech on Feb 3 2020 11:05 AM
Questions: I put in a new 8.5" clutch kit in my 62 cj3b, the the throw out bearing sits over an 1" from the pressure plate fingers. even if I depress the clutch pedal all the way down the the throw out bearing doesn't touch the fingers on the pressure plate. any thoughts as to what happened ? I put the old clutch out for trash a long time ago. so I don't have a org to compare to
Question By: brian on Jan 29 2020 7:28 PM
You have to set your free pedal travel correctly with your release cable. The proper measurement is 1" free pedal travel.

Questions: I just installed this kit on a newly rebuilt L134 in a 49 Jeepster. First off the fork in the kit was way too small so I had to re-use the old one. Then the bearing would not press onto the collar so I had to re-use the old collar with the new bearing. Once all that hassle was over it appeared to work however once we put the engine back in it does not work. I don't have anymore travel on the fork to adjust and my freshly rebuilt engine will not go into gear. So what is wrong with the clutch you sold me? I refuse to take my engine back out so Monday I will have it towed to a shop to have them put yet another new clutch in. If they tell me the wrong clutch is in it I am going to be furious!
Question By: Phil on Aug 31 2019 1:24 AM
This kit is not for a Willys Jeepster. You need part number: 930731ROD - that is the differences you are describing. Please email happy to help out.

Questions: I've got a 52 pickup with the F134. is this the correct clutch. Also the clutch appears to be adjusted nearly all the way out but it doesn't seem to release so it dies taking off in 1rst. i'm assuming this is all clutch related does that sound correct?
Question By: Brian Mclaughlin on Sep 1 2018 1:02 PM
This should be the correct kit but it could also have a 9-1/4" clutch. I would double check the measurement of yours before ordering. Thanks
Answer By: Willys Jeep Parts Tech on Sep 4 2018 7:42 AM

Questions: I will be installing a rebuilt F134 in my 54 truck. Which clutch kit do I need. The chart shows the 8 1/2 as correct only through 53. I will not be doing this work myself and want to have the correct clutch assembly for the shop that will be replacing the engine. I will not be pulling the engine prior to taking it to the shop.
Question By: Stan Howe on Feb 28 2015 12:00 AM
If you have what is most likely a 1953 Willys Truck with a 4-134 F head engine then you should be 8.5 clutch. This will be the one for you.

Questions: 1948 CJ2A T90 transmission. How do I know if this was a cable or solid clutch linkage assembly. It has a solid linkage, but it is bent to fit the bell housing.
Question By: Bret on Sep 6 2014 12:00 AM
If its a CJ-2A then they used a clutch release cable originally.

Questions: I have a 49 cj with a 231 ci V6 gm engine. Trans is t90. What clutch would I use for a replacement?
Question By: Roy Moulesong on Aug 19 2013 12:00 AM
It just depends if they kept the original flywheel or used the one out fo the unoriginal engine. You will have to check.

Questions: I have a 1957 cj5 and my clutch doesn't engage until about the last inch of pedal travel. Is there an adjustment that will fix that and get me to the engaging at an 1.50 off the floor parameter, or am I looking at a new clutch?
Question By: sean on Jul 28 2013 12:00 AM
You need to adjust your clutch release cable to accomplish this. You usually want about 1.5 free pedal travel.
Answer By: Willys Tech on Jul 29 2013 12:00 AM
Questions: My cj2a has what appears to be a Rockford clutch. What is the distance from the clutch fingers to the throwing bearing measured through the bell housing access panel after assembly? Mine seems excessive as the yoke must travel a fair distance before contact is made stretching the spring significantly.
Question By: Julius on Mar 29 2013 12:00 AM
You should have approx 1-1/2 of free pedal travel before it engauges the clutch.

Questions: i have a 1957 cj5 ,it has a 9 and a quarter inch clutch and presure plate my flywheel has a set of holes to take either one ,how do i order a kit for the lager clutch kit ,is bigger better?or should i go with the original8 and a half
Question By: louis on Mar 3 2013 12:00 AM
I would look at the wear pattern on you flywheel to make sure it will accept the 9.25 But if you have both drilled on there you could go with either. The 8.5 is plenty heavy duty.

Questions: Is there a way to measure the clutch diameter on a 1960 CJ-5 without removing it from the vehicle?
Question By: Tom on Oct 18 2012 12:00 AM
Remove the access cover on top the bellhousing. You can usually get a tape measure down there...

Questions: I am going to replace the clutch in my cj2a with PTO by removing the engine, as I want to check rear main oil seal and do some clean up/maintenance on engine while doing clutch. I believe it is easier than crawling under and removing trans/transfer case and PTO due to no lift. Question: is it better to take the engine out with the bell housing (disconnect from trans) or without (disconnect between bell housing and engine)? Thanks in advance.
Question By: Patrick McCauley on May 3 2016 7:14 PM
If you have a lift it is easier to drop the bell housing with the transmission. If you do want to pull the engine it may be easier to take the bell housing with it too...
