Japanese Timing Gears for 2F?

[oregonfj]

I found these on Ebay. Seller says they are made in Japan by Zuiko. Anybody use them? I'm somewhat leary of using the chinese ITM's after reading post here and would almost rather re-use my original toyota gears. They look like they are in good shape but I dont know how much longer the elastomer damper part will last.

There is another thread that I think was Jim Chenoweth who suggested a different solid cam gear, made by a US vendor and he also suggested keeping you crank gear that is on the engine, I wished if I had read that first, I bought this set from Joe, he has been critized by many on this board but I have always had good luck dealing with him, I thought the tolerances were good so I am going with them in my rebuild. My original cam gear I though initially looked good but after closer examination the rubber was all brittle and began to fall out, so solid gear it was. Best, Larry added linky

Did you contact them and they told you they were Japanese made, 'cuz I would think that is something they would list on the auction - When they don't it's usually because it's Chinese parts... There are Japanese Companies that manuf in China, too... I'd verify, if possible.

Or, these are USA made, Melling/Sealed Power:

Brew, can you verify if the gear set was made in Japan ?

His email response said made in Japan, but heck I'll take the American Mellings any day. Thanks for the link.

Just to clarify - ITM parts for the 2F are manufactured in the Republic of Taiwan and not China. Manufacturers in Taiwan that have made OEM parts for Toyota in the past. This was based upon a conversation I had with an ITM rep.

As far as your cam gears - It was recommended to me to make sure the gears have the elastomeric coupling to absorb chatter in the valve train. If it is solid the valve train can be noisy and excessive wear can occur. I bought Toyota gears.

I checked the boxes they both say made in Japan. Zuiko Ductile co

That's good to know. Thanks for checking. I might buy a set...

The Melling boxed gears are made by Zuiko in Japan.

Cheapest place to get them is Northern auto part.

I think Jim moonlights for Wikipedia ... JimCipedia ?

I think Jim is one of the reasons I am on this board.

I just pulled my 75 2f apart and noticed the cam gear is some sort of plastic/composite. It has small cracks from the center hole out to the smaller holes so I'm going to replace. Did Toyota ever use these stock or was it already replaced? I think I will go with the Melling from northern auto.

does it look like this? this is factory on f motors, don't know how long it lasted, but jim does

My 2/71 has the steel gear with the elastomeric ring. It's original...?

 

[Cruiserdrew]

Pretty sure a 3FE motor has a plastic composite cam gear. Looks like some 1Fs did too. Very cool.

A 75 2F, should have had a metal gear with the elastomer. Not sure how the one referenced in post #11 would have ended up with the composite gear unless It was previously redone.

I also have a vague memory that old Chevy motors from the 50s had a composite gear too.

 

[FJ40Jim]

Early F engines up through 69-ish? are composite, then steel through 1987, then back to composite through the end of 3F production. Dunno what gear is stock in HD engines for forklifts or FA dumptrucks.

 

[aquatech3]

Nuclearlemon. My 75 has the same gear yes. It was definitely the original motor too. Strange how they jumped back and forth from metal to
Composite. I ordered a Melling today so I feel pretty good about putting the metal gear in instead. Time will tell.
