Chainsaw Bar Sprocket Nose Tip for Tsumura 48FV34 3/8 058 063 Gauge 11 Tooth

Genuine Tsumura replacement sprocket nose tip — part number 48FV34

Bring a worn Tsumura bar back to life. The nose sprocket is the part that wears out first on a replaceable-tip bar, and swapping it is far cheaper than replacing the whole bar. Made in Japan.

A note on gauge:

Tsumura list 48FV34 as a .063" gauge nose. In practice it also runs on .058" gauge bars — the nose groove is slightly wider than the chain needs, which causes no problems. We have sold it for both gauges for years without issue. It will not suit .050" gauge bars.

Suits:

Tsumura replaceable-nose guide bars in 3/8" pitch - .058" or .063" gauge. If your bar takes a different pitch or gauge, you need a different nose — get in touch with your bar details and we'll point you to the right one.

Fitting it:

This is a workshop job rather than a field repair, but it's straightforward with the right tools:

Drill or punch out the three rivets holding the old nose
Slide the old nose out and fit the new one
Place the rivets through the mounting holes
Peen the rivet heads flat with a ball-peen hammer, working against a heavy, solid surface such as an anvil or vice

The rivets are included, so there is nothing else to buy.

Take your time peening — the rivets need to be properly flattened to hold the nose securely under load.
