fork lift carriage rollers.....

[frank horton]

OK....so the lower carriage rollers have gone on my 2000, Komatsu 2.5 ton f/l.....
I'll replace all 4.....
No problem, phone the parts supplier/all makes and the dealer but both say that the mast is non standard......
It seems over here the factory supplies the new f/l then the dealer orders a seperate comp to build the mast to the clients req's.....

There's no build plate on the mast.....so no idea who made it, esp as its so old......

My question what's the norm with the rollers....
A seperate bearing pressed into the roller or is the roller induction hardened and is the outter ring of the bearing....?

Apart from being a heavy job without proper facilities it's gonna be a marathon....
so wanted the new rollers in stock before strip down as I dont want 3,5tons of metal getting in the way......

any suggestions....

ps.....this is like living in the boonies engineering wise......
so has anyone machined out hardened rollers to fit a bearing.....?
I can get all kinds of bearings locally no problem......
anything f/l parts related are couriered down from the industrial north of Greece.....and it's not very reliable....
so in house / local repairs are a must.........
after 3.5 years here still not found an engineers, and all my machines are still in travel crates.......dohhhhh.....

thanks for any help.....

I've changed mine... they're not pressed on at all, they slide right on/off

one was a bit stuck, came off easily with a leaver bar tho

the way to do them is lift the carriage up so the mast behind it is in the air, put something in under that bit of mast to stop it coming down and then lower the carriage so it drops out of the bottom

don't have the mast too high in the air

thanks Knighty
but it's the actual roller bearing that I'm on about....
not worried about getting the entire roller of it's spigot.....
what did the bearing look like.....? obviously a ball race.......
was the ball race a seperate piece pressed into the roller body........?

I think they are a separate bearing inside the roller kept in with a circlip.

I'm not surer what you mean by the actual roller beating?

all of mine are the same, it's a single bearing with a big outer race?

random photos from google... but they're the same as all of mine
