Turf Gator Clutch Options


We currently have five TX turf gators that we use on our golf course along with a 2010 Gas HPX. They are 2007 to 2011 model years. Most have around 2,000 hours on them. I was curious what options are out there as far as primary clutch and secondary clutch replacements besides the dealer. The Turf gators are all Kawasaki FJ400D and the HPX is FJ400D v-twin

The primary clutches have never been apart according to the records. Most of the TX gators seem to shift fine, the HPX has a groove on the bottom of the clutch sheeve so it does not engage properly.

The secondary clutches have had new buttons put in before and some have been apart. On one of them the sheeve has a slight bend to it but is still usable.

I have taken apart snowmobile clutches before so I understand the workings of them. I have heard that MBdiagman on here does clutch repair as well. Would it be worth repairing a 2K hour clutch or should it just be replaced? What kind of aftermarket support is there for replacement clutches or a good priced vendor to deal with? I am not looking for speed, just reliability and longevity.

Thanks for any help

Firstly unless you want to modify the machines there are no options

For me 2k on a clutch thats worn calls for a replacement.

That being said however i have seen tons of clutches work untill they simply died.

Firstly, grooves or bumps on the sheaves is a replacement without a doubt in my opinion.
Again ive seen them where the customer chugged on but its not healthy for the belt either.

Secondly if you know how clutches work these are actually rebuildable to some extent.
This is a hpx driver clutch and you can replace the "clutch spider" when the rollers get worn and is a job we do often aswell

Now we dont do alot of the tx clutches and we normally replace them outright but theres a spider kit for these aswell.

Hell if i know if they are even available because like i said ive never done a spider on a tx.

Lastly the rear varios only wear on the tracks and the little rubbers wear out.
Here we simply call them little [email protected] on the rear vario so excuse my lack of terminology lol.
Again the runner thingies can be replaced but only if the metal is not worn or weird looking.
Once theyll look bad youll notice soon enough.
The rear once will normally not break in any place other than wear out an those spots or develop play

So to be honest: replace the front hpx vario, repair the rear if possible and inspect the tx varios for damage play etc.
If they get sticky or have alot of movement on the shaft its time to move on.

Adendum: clean them, check rollers on spider and also check the aluminium that the spider slides in as this will also wear.

And again: once the alumium on the rear of the sheave or the sheaves are worn its game over.

Thanks for the reply.

In your opinion if the primary clutch is replaced should the secondary clutch be replaced as well so they work as a set? Thanks for the diagrams.

I replaced a primary and secondary clutch on a Kawai 400FE club car recently. The original clutch on there didn't seem terrible to me but what a difference new clutches made!

No need to change them as a set, usually for some odd duck reason if the rear vario is worn the front is upon inspection likely to be bad aswell in 8 out of 10 cases.

But ive seen rears outlive 2 or 3 front varios.
Rear varios dont do much except follow the front while it does the backbreaking work.
It simply wears and fades out over time
Again the sheave could wear here aswell but there isnt any slippage here either.
Again, sheave with bumps are bad but i hardly see that happen unless the customer really makes it to the end of the lifespan

That new vario feeling is also gained by cleaning it once in a while by the way 😉 varios like to be cleaned and you wont believe what kind of dust could be in them.

My floating half is missing something. I don't see any sign of the bearing it shows in the picture (6x4th)or even a snap ring groove. The hole diameter is .080 larger then the shaft. Its been clanking for years and I finally decided to look at it thinking it would just be the wear pucks but they are fine. Can't believe I'd have to tool and die something to fix this or spend $650 for a new primary. They don't even give part numbers for the pieces they show. Any thought?

I would replace it if its missing parts, rebuilding a clutch is a specialist job.

But you can ask mbdiagman if he can help you.
If its salvageable he can fix it

Not really a specialist job pretty basic stuff compared to the automation equipment I build. Talked with The parts guy at Deere and he sees what I mean about the part numbers not being shown. So he's making some calls to get more info. They might be included in the spider box just not shown. I'll keep yous posted.
