Multico PM20, PM21 morticer parts

Parts for the Multico PM20 and PM21: chisel bushes, the brass-tipped chisel screw, chisel setting jigs, the MCL cone sharpener, the side stop assembly and the timber clamp handle. Three more parts are for one version only: the gas strut fits early PM20s, the 115 V capacitor the PM20 built for the US, and the bolt kit PM5634 door stands made up to 2002.

Choose a chisel bush by the collar of your chisel, not by its cutting width.

Frequently asked questions

Which chisel bush do I need?

Measure the round collar at the top of your chisel, not its cutting width. Chisels made for imported machines have a ¾″ (19 mm) collar and take the PM3875 bush; chisels made for British machines have a 13/16″ (20.6 mm) collar and take the PM3921. A ⅝″ (15.9 mm) collar takes the PM4146. All three are listed for the Multico PM10, PM12, PM16, PM20, PM21, PM22 and PM22T.

What gap should I leave between the bit and the chisel?

About 0.8 mm (1/32″) for chisels up to ¾″, and about 1.6 mm (1/16″) for larger ones. Set it with a coin as a spacer.

Which gas strut does my PM20 take?

The H-43.5059 strut is listed for early PM20 machines only. For a later PM20 or a PM21, send us the machine's serial number, or a photo of the head and the strut, before you order, and we'll check which strut it takes. Support the head before you take the old strut off.

Do you have parts for a US 115 V PM20?

Yes: the H-54.5001 motor capacitor is listed for the PM20 built for the US, which runs on 115 V. Before you order, check the voltage on your machine's rating plate and the values printed on the old capacitor. Unplug the machine before you open the motor's terminal cover.

Part not listed?

Send us the Multico part number, or a photo of the part and your machine's model, and we'll check.
