BR00.45-Z-1014-08A | Repair kit for crankcase sealing surface (Titanium Putty H. P) 2-component material with acetone universal quick-cleaner Order no.: 10765 | ITW Devcon Industrial Products GmbH |
1 | Seal all coolant bores (1) to be machined with fabricated stop plugs (2). |
2 | Mask off remaining coolant, engine oil, pushrod, cylinder head bolt and cylinder bores at crankcase sealing surface with tape. |
Surfaces to be machined must largely be left blank. |
3 | Clean surfaces to be machined with corrosion pits and/or pittings (arrow) extensively around coolant bores with a wire brush until these surfaces are metallic bright. |
W01.40-1079-11
4 | Bore corrosion pits and/or pittings (arrow) with a ball cutter Ø 5 mm (depth 0.7 to 1.0 mm). |
Use hand drill. |
5 | Degrease surfaces to be machined extensively around coolant bores with acetone universal quick cleaner . |
W01.40-1080-12
6 | Mix both 2component materials (base material and hardener) in the correct mixing ratio at the volume 3:1 or the weight 4.3:1 with a putty knife for at least 4 min. |
The 2-component material mixture should have a consistent color, ideally not have any air bubbles, be putty-like and free of lumps. |
7 | Apply 2-component material mixture so that planar using a putty knife onto the area (arrow) to be machined. |
To obtain a smooth surface, wet putty knife with water and rub over 2-component material mixture. |
W01.40-1081-11
8 | Allow 2-component material mixture to cure at a room temperature of 20 °C for approx. 4 h. |
The curing time will take longer for a low room temperature. Never use an open flame for heating purposes. |
9 | Remove excess 2-component material mixture using a putty knife, carefully scrape repair points so that flat if necessary. |
10 | Remove tape at crankcase sealing surface and clean tape points |
11 | Pull stop plugs out of coolant bores using a pliers. |
