belt tensioner -- rebuild possibility

[YNOT]

G/Day beansathome-- thanks for heads up on your repair -- from pics it appears that only bushes may have been worn -- only too easy to replace --
but note the ferret advice & if possible use Aecetal ( as opposed to nylon ) for replacement bushes -- on Tony's photo the actual " journal / clevis ends also appeared worn & some minor machining would be reqd . Congrats on your repair -- replacement ( especially at what appears to be exorbitant cost ) of whole system appeared extravagant waste. Regards Jim.

Correct, the insert that goes in the middle of the bush is also worn.

G/Day The Ferret,
Gee mate 'time on m/c's say miller 15 min ( no real set up issues ) lathe for 2x bushes Acetal ( cuts & finishes dreamy ) 20 min. -- mtls say $ 5.00
don't look too bad --- BUT haven't had a look at actual part to evaluate structural integrity in journal area although from photo looks ok. -- some quick calcs say we don't need lots of parent metal to far exceed expected loads -- looks like Glen William just jury rigged his with apparent success
will assess part when in hand and talk later. RegardsJim.

G/Day Glenn. thanks for posting your repair-- done a good job by the sound of it -- all relevant to the designed function of that part ( non rotating uni-directional compression ) you may have to add The Ferret's suggestion of Acetal bushes in the near future as the nylon may prove ( as original ) too soft -- I suspect what happens with this part is excessive wear of nylon bush allows eccentric load of idlet pulley & destroys idler bearing ---
really Nissan Design fault should possibly have been a recall --- if it was Ibet they would soon have supplied a repair kit PRONTO.- -- FULL MARKS for your innovation. Regards Jim.

i wish mine was only the bushes. when i pulled it off the car it literaly fell apart i had to cut the belt to get it off. the center shaft in the tensioner was actualy bent and worne down.
so i had to replace it or i would have looked at just the bushes.. i dont think any one relises how easy this is to repair on there own.
i would love to have some spare bushes on hand. its a commen problem

G/Day Tony, OK mate ,put the part in your truck -- will be heading to warmer climes in few weeks -- have to go thru Moree --will swing over to your district & meet -- a mobile mechanic yes figures - too wide experience repertoire to be in dealership or similar. -- from other replies a repair / change over replacement for this item ( s) looks feasible. would be good to have a couple in the kit.-- I think I can re-design/construct original to eliminate defect or at least extend service life to that which Nissan has /was known for. Being a mobile mechanic you should PM me on jbuild45@yahoo.com.au . BTW should you ever wish for a career change you would make a great candidate for a training officer in the Coal industry.
on OT that work done by Dad is awesome -- might be able to meet the master!! Regards Jim.

Just be wary mate, there are about six grades of Acetal, some are soft like the green, some are a bit harder like the blue, there is black and white.
Some turn off with an endless swarf and are a pain as they fly everywhere and wrap around the chuck, you need to back off every few secs to break the swarf.
I use a white one, can't put ma hand on the code number, but it comes off in a powder form, is very hard and you can get a good finish off the tool, standard Hi-speed tips are good, wear a mask.
Rpm about 1500 seems the go but watch the heat, tends ta drag with being gready, fine cuts seem to work better when close.
Cheers, ferret

G/Day mate, thanks for the info -- you are spot on -- I have the black in stock is hard & wears well - used it for replacement bushes on conveyors -- given good service,machines well -- the white you mentioned might be better if it is harder as I suspect original is crushing out due to constant static load -no rotation to speak of -- haven't seen part in the skin yet-- will let u know when am at it. Regards Jim.
