Makita Dcs520 with broken casing for bumper spike

[Jim372xp]

I found this enoyning little problem today on my 520.Problem is I don't know what to do now, I took the bumper spike off so its not stopping me using the saw but it's repairing it to put the spike back on that concerns me, do you think it's possible to tig weld it in situ without stripping saw down or would welding it in situ put to much heat into the crank case and damage gaskets and seals etc , your thoughts gentleman please :confused1:

i broke my 115 which has the same body as your saw on the other side but mine broke off the av casting watching with interest as i stripped mine down for parts

Forget welding it, there is a lot of magnesium in the casing alloy and personally, I don't think it will work.

 

My suggestion is to take off the chain catcher and the dog spikes, modify the lower part of the dogs by welding in a further plate so it mounts to the chain catcher mount - you could even make a chain catcher in to the assembly but it would be of steel rather than aluminium which may cause damage to a chain when coming off.

 

DON'T leave the chain catcher off if you do this for obvious reasons!

Is it possible to make a little plate that has 2 holes in, one to mount using the chain catcher fixing and bolt the the spike through the other?

You evev seen that film "Twins",I am 6'2"that makes you the short fat one:lol:

Fat yes. Short no. 6 foot 4 here.

Make a new chain catcher , out of aluminium , that's long enough to bolt through the dog and epoxy the broken piece back in place.

Shavey that sounds very unfortunate that you have to break a perfectly good saw for parts, I was thinking about my problem and thought of welding a piece of steel to the bumper spike and fitting it on the clutch cover side and using the bar studs and nuts to keep it in place like whats on my mates husky 281 set up.
