4age gilmer belt drive question

[ke_25]

Hey,

jut been to the engine balances.. and my crank pulley for 4age has a little bit of play, i assume the hoel is about .5 to 1mm difference in size, and teh rebuilder siad this is to of concern, and should be "tight" fit?... has anyone else come accross this?

Cheers Shaun

[Rob_GTZ]

Yep it should be a very tight fit, if it is able to move it will cause damage to the pulley, the crank key & keyway. There was a guy in dunedin who had this happen after running his gilmours for 10000 kms

Agreed, I'd be very wary of running unbraded/chinese quality pulleys sold thru trademe etc. Quite often they're poorly balanced and made of crap quality aluminium, and tolerances more measurable with a tape measure than a DTI/Micrometer.

[Mr Revhead]

most definitely that is a major concern
return it to where you got it from and get a refund/replacement

um the ones on tm are NZ made, the seller states that and NOT china made. so looks like the china bashing not always work.
poor quality nz made crap

IIRC they don't have the harmonic rubber bit in the middle of the lower pulley, right?

correct.

[ke_25]

Hey, yeah I was wondering if anyone else had this with gilmers..or if it was just my set, and appears someone has. I will get in contact with the guy and see what he says.. Yeah I thought it should be very tight fit.. It's rwd application and needed them to get round my loss of my ae86 pulley..and liked idea of gilmers!!

What's wrong with solid pulleys?? And has anyone ran the t3 pulleys? These may be my only other option if I can't get the gilmers sorted ,

Cheers for your help..,

The rubber core ones are harmonic balancers.
Since your engine is being balanced perhaps once you sort the issue of it being a loose fit you could have your pulley balanced along with the crank etc.

[ke_25]

Yeah crank etc Is being balanced ATM... They said they door allindividual thn together to male sure there's no 'stack up' he said thati should me able to put the engine together with that all balanced minus the crank pulley andnit should be fine being a light pulley once I sort it, and just get that balanced individually.

[frost]

no it dont work like that. balancing is to do with the entire assembly
crank pully with bolt, crank, flywheel with bolts, clutch cover with bolts.

they need all of it to balance the rotating assembly. in most cases they drill material out of the flywheel to balance it but sometimes from the front pulley too. if you dont have all of that then your wasting money

[ke_25]

he siad tehy do they crank alsone, the fly wheel alone, and the pulley alone, then place them all together to check there is no stack up across the whole system? t check it is all fine. and them he said he can make sure the pulley is balanced, the rest of it will be (crankk and flywheel assembles iwth all bolts) and it shoudl be fine?

[Bazda]

Yes thats fine, as long as you get the pulley balanced really good alone it will be fine.

As for harmonic balancers, with gilmore systems there is alot less stress on the belt as you dont have to make it as tight as a v belt system. So its better than having a solid v belt pulley.

And it needs to be tight.

Personally I would be buying a Ross harmonic balancer.

[ke_25]

they onyl do these for fwd applications i was to believe?

If you contact them, they can do for anything.

I was trying to do a group buy to lower the price but no one wanted one.

[rollaholic]

whats the TM user name for the gilmer stuff?

one of the guys on GD works at endeavor engineering in TGA, and has had some of their gilmers on his car for quite a while now. i haven't spoken to him in ages but dont think hes ever had any issues with them

his username is hachigo on GD if you want to hit him up

im not convinced i see the point of a gilmer drive system on NA 4age though

(or have you got a blower on it? i hope so! <3)

[ke_25]

not a n/a.. just a turbo.. and wishing to push 30psi plus! its in RWD and i have seemed to of lost my rwd crank pulley, as running the ae86 set up on my 20v.. so this was a option. Yes its thoruhg allen at endevour engineering, got it all back from balancers today and th crank pulley does have slight play, i can her it tapping when i rock it. will wait for their reply, cannot really fault there craftman ship, the quality is amazing. i just want to get this sorted, it sould be a one off problem..

i did notice on a k series which the key way wore it out.. they manufactures a steel inner, i think this may be a option. still waiting for his reply, he was great to deal with.

[jondee86]

Some people might call it a harmonic balancer, but if it has rubber or
urethane or silicone fluid, it is a harmonic DAMPER. Its purpose is
not to compensate for static or dynamic out of balance. It is there for
damping (absorbing) potentially damaging torsional vibrations.

See here... http://www.fluidampr.com/HOWITWORKS.htm for
a better explanation.

They are a solid (or not so solid) alloy pulley, if there were problems with the strength of the alloy; perhaps a steel insert for the pulley where it fits on to the crank, an option?

not really as the insert could spin it self free after a while. you could grub screw the insert but then that causes more trouble. after that your better off buying a better quality pulley,
