Tanaka ECS 3500 Oil pump
« on: January 27, 2018, 02:03:31 am »
In the late 90s someone left a Tanaka ECS 3500 in my shop and never came back.
The complaint was it wouldnt start. But if fuel is poured into the inlet, it would start, over rev and stop.
The guy was supposed to pay a fee upfront as advance, but promising to return, but never came back
Last week since it was sitting there occupying space I thought I would sell it as scrap. But when all the dust was wiped off I noticed it had not been used much and decided to get it going if possible, business being virtually at a standstill in 2018 I had all the time I needed.
It took me about 20 minutes to confirm the cause of the problem. A ripped inlet manifold probably from over enthusiasm when freeing a stuck guidebar .
Parts for a Tanaka a rarity, I managed to modify the manifold of a cheap Zenoah clone from China and the engine fired up at the first attempt and runs as sweetly as it did when it came out of its box years ago.
But, now I find a real problem. The oil pump seems to be kaput.
From the old contents of the oil tank I gathered that the guy who owned this saw had been using used motor oil of the worst kind, with a lot of metal sediments.
There was no oil pickup body and the oil tube had a big tear.
Once more I delved into that Zenoah clone for its oil tube and pickup body.
Still no oil. I think the pump is a goner.
Are parts for this saw still available? Expensive or reasonable?
If possible I would like to get this saw to full working condition and keep it.

See if you can find an Hitachi lookup.  doesn't show Hitachi any more.  I needed a clutch for a CS51EAP Hitachi(Tanaka TCS51EAP) clutch was half what it showed under Tanaka same clutch.
