almighty15 Posted March 1, 2015 Share Posted March 1, 2015 The wheel on my new KM Baja keeps coming off. The pin that holds the hex on keeps coming out when in use and I put it back in and after a while it comes out again. Luckily I've managed to find it each time but it shouldn't be doing it at all Any idea how to fix it? These ideally should of been threaded and screwed in.

shdaxner Posted March 1, 2015 Share Posted March 1, 2015 is it a similar setup to 8th scale whereby there is a grub screw inside the axle bit which when tightened holds the pin in place? Quote Link to comment Share on other sites More sharing options...
Renllek Posted March 1, 2015 Share Posted March 1, 2015 If you have a look down the end of the outer drive there 'should' be an allen bolt. you assemble everything, put the pin through and then tighten that allen bolt up. That stops the pin from falling out. 1 Quote Link to comment Share on other sites More sharing options...
.AJ. Posted March 1, 2015 Share Posted March 1, 2015 Put a cable tie round the hex to stop the pin popping out Quote Link to comment Share on other sites More sharing options...
Tug Posted March 1, 2015 Share Posted March 1, 2015 Or insulation tape. Quote Link to comment Share on other sites More sharing options...

Renllek Posted March 1, 2015 Share Posted March 1, 2015 That did the trick!! Major respect!! I only knew that cos i had to strip the rear hub lastnight as i snapped one of the parts in a roll, had to hammer the pin out with a drift. stopped for 5 minutes while i had a smoke. While i was doing that i gave all the parts a good inspection and noticed the allen bolt, was much easier getting the pin back in after that!! haha Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted March 1, 2015 Share Posted March 1, 2015 To avoid embarassing problems.... 1) Go to HPI website 2) Download Baja SS manual 3) Read the document section relevant to whatever part of your car is giving you grief.... And THEN break out the tools HPI give the manual as a free download, and it is well worth having 2 Quote Link to comment Share on other sites More sharing options...

almighty15 Posted March 1, 2015 Author Share Posted March 1, 2015 My buggy already came with a manual and exploded views, I just never thought to look at it. Quote Link to comment Share on other sites More sharing options...
flatout! Posted March 1, 2015 Share Posted March 1, 2015 I tried all them things, tape, rubber shaft boot cut down, locktite, tape and a rubber band, not one kept these pins in, iv put a nut and bolt on there with a spring washer and iv never had any trouble since, i used the bolts out of the top rear shock tower of a fg style rear end 5th scale, there only half thred to, they have a smooth shoulder on the top part of the bolt, purfect so the threds don't chafe the hell out of the axel and your alloy hex, Quote Link to comment Share on other sites More sharing options...
Renllek Posted March 1, 2015 Share Posted March 1, 2015 i got the exploded view but no manual that i can recall, but yes i didnt think of looking at that first, have only ever used it for part numbers when i needed a new part. Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted March 1, 2015 Share Posted March 1, 2015 Make sure you get the SS one .... the SS is the kit version, and it shows step by step builds for each section. http://www.hpiracing.com/instructions/10610 Very handy, and just as relevant to a KM 2 Quote Link to comment Share on other sites More sharing options...
