|
|
I seem to recall a solinoid operated 24 volt M38 starter. Is there such a thing? A fellow/friend with a sore foot is wondering. I see 12 volt starters, but I'm not sure the tooth count for a CJ5 ring gear is the same as military. 124, 129 tooth counts? Confusing. You could tap one of the 12 volt batterys , but the modern solinoid starter may not work with the flywheel. Anyone done this? Thanks, John |

John, The 124 tooth flywheel is peculiar to the early unsealed M38 bell housing. The 129 is common to both the CJ5 and all the M38A1's. This of course assumes we are talking stock jeeps. The stock prestolite CJ5 12 volt starter uses a 129 tooth flywheel. It is a followthru Bendix drive which means the force to move the bendix drive gear in mesh with the flywheel is rotational thru the starter's electric motor. This all means you could have a shop rewind the CJ5 starter for 24 volt. This would only leave the need for a 24 volt intermittent duty solenoid rated above 200 amps which should not be too hard to find. _________________ Wes K

Brothers Oilleaker and Wes have always got my six, thanks friends. It's my M38 and unfortunately my foot. A chronic condition from injury years ago.
A great deal of pressure is applied to a small area on the starter plunger to
activate the starter.
The jeep is stock 24V, 129 T flywheel, MCZ4001UT starter. Can the manual switch on the stock MCZ4001UT be replaced with a 24V elect solenoid? Then perhaps mod the orig foot plunger to activate the solenoid?? Interesting possibilities..
Scratch that idea. A quick trip to the Ord 9 clearly shows the starter drive is yoke actuated by the same lever that actuates the switch. I just need to "cowboy up" and beat the medical condition. And I will. _________________ keep 'em rollin'

Thanks for your reply Wes. We even considered tapping a 12 , running a separate battery cable for one of the new 12 volt starters if it would mesh with his flywheel and bolt pattern. Leave all else stock. John |

Rick,
Give me a call..... Rob in Boise....I may have a 12 v starter or two... if you're interested..... you can get me at flxdsn@gmail.com I think you came by my shop a while back.
I remember Ron F had a unique 24 v solenoid operated starter on ebay a while back....looked homemade but well thought out.
a few M38a1's in the shop right now Also another friend finishing one up right now.....soon to be a few more in Boise....
Rgds,
Rob _________________ ldt465 |

There are dozens of old starters with electrical solenoids used to move the bendix into contact with the flywheel. They work fine. The Chevies 55-59 used one. The problem is adapting one to the MCZ4001UT starter. Tearing up a flywheel and pulling a flywheel off is the result of a less than perfect adaptation. Only a fool would take that route instead of adapting a stock CJ5 12 volt starter which we know will not damage the flywheel and we know fits the hole. _________________ Wes K
