hey harley I know I am becomin a pain in the ass but non the less your my best source of info lol,anyhow I have been workin on my sled finaly got the damn clutch off so here are some questions I have for you.
#1. do I have to keep the dust cover on ,upon pullin it off I had a bunch of black powder dust come out ,seems to me it keeps more in than lets out .

#2. the sping is silver an very week now I like to drag race so what do you think I should put in it a new silver or somethin with more resistance.

#3.I have been lookin at the thunder clutch kit an I can make somethin simlar,or should I stick with what the manual says.( not that I am into following the distructions unless I am completely lost lol).

#4.on the driven clutch the belt drops in alot more than it should anotherwards it doesnt have that little bit above the clutch.

#5.why in the hell does this thing engage so soon I mean we are talkin just fethering the throtle an you had better be hangin on cause the sled will be movin.

so these are just a few of my questions for now trust me I am sure there will be more,you want a good laugh I plan on tryin to set some new race records with this thing even if it is 30 yrs old lol grass drags here we come ready or not lmao anyhow thanx for any info you can provide.

Storm,
#1.. It is recommended to leave the dust cover off. THe black dust is from the guide buttons and fiber washers wearing down. The dust cover would not allow proper cooling and could overheat the bushings in the weights and rollers
2..The original spring was silver, replace with the same or the next one heavier
#3.. I do not know anything about the thunder clutch. Stick with JD
#4...A new belt should not drop down, it should be at least flush. You can remove a shim to remedy this.
#5... If the primary spring is very weak, the clutch will engage prematurely. The factory engagement rpm is 3700 -3900 rpm

in response to #5, what is your idle at? if your engagement is 4000 and your idle is around 3500, you'll be moving quick. all of my idles are set very high so it doesn't bog too much but once i get off the sled starts moving when warmed up. turn your idle down to about 2500 and you should be fine. also leave the dust cover off.

I keep seeing the response to leave the dust covers off, 100C should be left off also correct? Mine is on the clutch yet, did Deere recommend this also over the years?

Hi Guys,

Deere stopped using the dust cover in either mid 76 or 77. It originally came on all the 100-C, 101-C, and early 102-C's.

Just as Harley stated, the clutch runs cooler without it, and that will prolong bushing and belt life. Therefore, it is a good idea to remove the dust can from any Comet clutch that still has it in place. You don't need to remove the clutch to do it, (although it it much easier to put the cover back on with the clutch off), just remove the retainer bolt, and then the cover bolts. The dust can comes off with the cover, as it is samwiched under it. Note that spring tension is pushing on the cover as you unbolt it. Be careful, and consult your service manuals too. Note that this is also a good time to check for worn wieghts, rollers, pins, bushings and springs.

I hope this helps,
-Rainville

I have a question?? If the earlier comet clutches ( 100's & 101's) had a replaceable bushing that the dust can holds in place, wouldn't you have to replace the cover with a new style cover to remove the can if the can holds the bushing in place on the older covers/clutchs??

hey harley not to pick on you but you old timers need to move into the 21st century. the thunder shift weight are a great way to go on the older sleds. it lets you set up the clutch how you want and need it with out buying a ton of weights. me and the old man have this discussing at least twice a week. once you start playing with the weights they are real easy to set up and change. right now i'm running them on 3 of my deeres and they work great.

Wade,

Ken,

I have a couple 100 and 101 sitting here, but I never noticed that the bushing is retained by the dust cover. I don't quite understand how the bushing could pop out with the spring tention against it, but obviously there must be a way.
