Distributor

[Can1991Ram]

Is there any differences between the 2.0 litre with a carb distributor and the distributor in my 1991 2.4 litre with Fuel Injection?

[geezer101]

No vac advance on the 4G64 distributor. They are both the same as far as gear drive and body dimensions so they will interchange.

I'm assuming the 2.0 is a hall effect dizzy too?

[geezer101]

Yes. AFAIK none of the trucks after 4G32 Gen 1's had points or optical triggered ignitions in them.

I wonder if there is a way I could change it to a magnetic pickup... I should pull out my 2.0 distributor and have a look.

Can1991Ram ~ permission to add other distributor questions to your thread..?

I need a 1986 (4X4 truck) vacuum advance diaphragm actuator but I can only find a 1984 actuator on eBay ~> will it fit on the 1986 distributor..? It looks similar/same...

Question #2 ~ O'Reilly's has a rebuilt Cardone distributor for my truck on the island $153.00 core $85.00 ~ should I just buy the Cardone unit or try fixing mine ? My dist has new ignition module cap & rotor ~

Here is O'Reilly's dist: https://www.oreillyauto.com/detail/b...r-ram-50?pos=0

NEED ADVICE

I would get the rebuild. Then you know it has good bearing and has been thoroughly checked.. plus has a warranty

I hear you bro - fixing n fixing n fixing only to keep finding more things to fix NOT to mention rework of fixes that don't completely fix !!! Today I ordered a 1989 MM dist vac advance actuator unit from my local O'Reillys -- $23 shipped they said if it don't fit return no problem for full refund -- on paper it looks like it might work -- if not, O'Reillys has one cardone rebuilt 1986 dist on Oahu hmmm I'll get it then if my attempted fix don't work --
Mah truck is gobbling gas like it has a hole in the gas tank !!! I'm gonna rev it with timing light to see if centrifigal advance works & vacuum gauge the dist vac hose to check for ported vacuum proper operation

Can1991Ram ~ Thanks again for allowing me to add my distributor info to your thread ~

1) Installed a new distributor vacuum advance unit on my 1986 Dodge Power Ram 50 with California emissions and Mitsubishi distributor

2) Internet does not list any vac units for 1985 & 1986 MM or Dodge Ram50 trucks ~ the closest year they list is 1987 to 1989 ~ other older & newer years have units listed ~

3) I took a chance and bought the 1987 to 1989 vacuum actuator and it's a perfect fit on my 1986 truck and can be installed without removing the distributor (just need an offset Phillips screw driver) ~ OH it came with two new mounting screws too ~ not cadmium gold plated tho but the silver plating looks good ~ the OReilly part is also "Made in Japan" ~ no need to buy a rebuilt distributor
both centrifugal & vacuum advance work fine now ~

4) This is the unit I bought from O'Reillys:
