Want to change the fanbelt on this .What bolts to remove to allow enough access down on the coupler ?i am guess unbolt at flywheel and back it off? Are there bolts on the pump that have to be removed ? Havent crawled under in the snow to check yet .

I remember changing belt on them is a pain there is a bolt on the piece that the pump spline goes into that has to be loosened I also remember dropping the counter weight loosen the pump and pull it out of spline I sure would wait till spring if it was me
Thanks .Sounds like a plan .Hopefully the belt lasts till spring and i'll back to you then.

I think it would be ok for emergency fix but I think the right belt would make me have piece of mind

Actually have a couple of link belts for emergencies, up on the wall in the garage.
If it’s not a serpentine belt, like my Case is, I would definitely run a Link Belt, forever.
As much as I despised them 30 years ago, these days, the seem to last better than all the cheap crap coming from China or wherever.
I have had a couple of Link Belts on some stuff that’s been on for over a decade. The sheaves are so worn and didn’t feel like replacing, on my father’s old 9n and a beast of a JD mower drive belt that previously burned up 2 supposedly Kevlar belts.
Have no idea, why they are so tough.
Still, I generally like to fix things correctly but as i get older, just want it working.
That damn JD mower has had the deck rebushed and re pinned twice and still was burning up drive belts.

Mine is just a regular 1/2 x 60 inch v-belt for the alternator

A link belt would be a viable option for you.

I changed the belts on my 426 and it was not that hard. The splines were a bit stiff but some Kroil and a prybar did the trick. It was 3 or 4 bolts on the coupler.
Would something like this work Dave?https://www.amazon.ca/Wadoy-Adjusta...Q4NN/ref=cm_cr_arp_d_product_top?ie=UTF8&th=1
So the bolts that hold the coupler to the flywheel/harmonic balancer then all of it slides towards the front pump and all?Is the pump not held to the frame?

You do know there are clamp bolts on pump spline side
Never looked .So thats how it slides back
Just crawled under and had a look.Looks like fun to even get at those clamp bolts

Correct, Link Belt till spring.
Then procrastination will fit the bill and who wants to lay under a backhoe.
By then, the Link Belt will have grown on you.
Lol

That's a great idea .Will the one i posted with the link above work or do i need something better?And now my next question.All 3 loader cylinders leak .I bought 3 seal kits to repair them.I tried earlier this afternoon to loosen one of the end caps and no go.Had an 18 inch pipe wrench and a bar and it didn't budge.Everything on these seems to be a pain lol

Yep, the Link belt you had will work as long as it’s long enough and it’s a standard V-belt pulleys.
Haven’t had a 416 for 20 years but remember it as a V-belt.
Do not be that guy.
Buy the right spanner wrench, look for other threads on using a ratchet strap or quick clamps to keep it on if you’re doing it yourself.
Use a peening method, if it’s really bad, try not to use heat.
Protect the chrome rod with a split paper towel tube and some tape, or whatever else works.
Use the pin that the cylinder it came out of to hold it for taking off the piston nut, instead of fighting with a vice
Use a minimum 1/2 air impact to get the piston nut off, making sure to have a good air supply and oil the crap out of the gun, just before use.
I always snap the bolt, right on the end, with a 5 pound hammer, just to let it know it’s going to come off one way or the other.
If you don’t have a tourqe multiplier to re-tourqe, which I don’t, use other measures or take it to a hydraulic shop.
I always clean the threads of the bolt and the rod, heat the rod end with the threads up to 2-250 degrees and using red LockTite, make sure my compressor is at max PSI and run it right in.
Good Luck!
