KF82 Cam & Cam Gears

KRAZYMATT

I have a 91 club car ds the motor is disasembled right now and i noticed on the camshaft where the gear is rivited to the cam shaft it is missing the metal plate that is shown in the pictures i see of new cam shaft online? is this plate needed seems like it must act as a stifferener? i know some of the lawnmower kawasaki engines the goverenor is in that location? just wondering the purpose of the metal plate on the club car motors was since they are goverened in the rear end? also the cam gear has some play liek the rivits arnt pulled in tight? i dont know if they were tight when it once had the metal plate and it was removed and now has slop? is there away to smash these rivits tighter so the cam gear stays tight to the cam shaft or is some side to side play normal? (about 1/8")

This shows a new cam with the metal plate.

Here is my cam

And this picture was taken pushing the gear up against the land on the cam and pushing the rivit back to show the slop in the rivits...

I would think you would need the plate, they should be easy to locate because there are a lot of dead cam gears out there. I have heard of people replacing the rivets with grade 8 nuts & bolts & permanent Loctite on the threads.

i had thought about it but the rivits are about the size of a #10 bolt.

Sometimes nylon gears will get brittle, (not sure about club car) I would be careful if you decide to press or hammer those rivets tight. Might be better go go with bolt/nut & loctite.
That first picture shows some chewed up areas on those gears, did you have some chips floating around? Make sure you get them all out.

I didn't say size 8 I said grade 8, make sure to use a guality nut and bolt no matter what size they are if you go that route.

Good Luck

i ended up using 2" #8-32 sockethead cap screws & a couple washers. (i chose the 2" length because it gave me almost full size unthreaded rod 1 1/2" through the cam and gear and just enough thread to lock it down with a nylock.) ran a nylock all the way down to nip it up tight then cut the excess of with a cut off wheel. used red loctite on the threads. seems to be holding fine.

yes the case was flushed out. the previous owner had snapped a rod and repleaced it but it looked like when it broke the oil level sensor took a hit but was never fixed. it was pretty beat up. when i got it apart and oil drained i found 1 of the 3 small mounting screws for the oil level sensor in the bottom of the case, im guessing that must of sloshed around between the crank and the cam gear and caused those small nicks in the cam gear. the gear engagement seemed to be plenty also the fact that they are helicol gears helped in this situation. removed the oil level sensor all together and re assembled the motor. seems to be fine!
