Questions: Does your company sell a bolt on timing pointer for the L134 engines? Or is there a any suggestions on how to set TDC on the pulley? Thanks
Question By: Lucas on Apr 24 2014 12:00 AM
They really dont make anything like that. You should be able to get that from your flywheel markings.

Questions: I have a 46 CJ2A that I have had for years... It runs great & lots of fun, until I heard a noise coming from the crank pully. I removed the fan belt and noticed that the pully was very loose and rotated back and forth on the crank shaft ?? I tried tighting the crank shaft bolt which was tight and did not fix the problem? Do you think the pully key failed or do you think the pully & key need to be replaced? How do you get the old pully off without damaging it? What kind of puller do I need?
Question By: Richie on Jan 17 2013 12:00 AM
There is a key that locks it into place. That is probably worn. I would take a look at that. You will probably have to go buy a puller to get it off.

Questions: What machining is required for proper fit? Do you sell the key that goes between the pulley and the crank? Are the sheaves for wide or narrow belts?
Question By: Kirk on Jan 1 1970 12:00 AM
They are for the narrow belts. You have to lathe the inside diameter hole to fit.
Answer By: Willys Tech on Jan 18 2011 12:00 AM
Questions: Is the pulley diameter wide enough to fit an M38A1? Original is 6 3/8.
Question By: Jasper on Oct 23 2010 12:00 AM
Yes this should work just fine for it.
